Dead, malformed, and wilted foliage is an indicator of contamination.
Also, the ill patient may be the first indicator that a BW agent has been dispersed.
The presence of dust is an immediate indicator of contamination.
The switch proper is on the rear of the switchboard, and the hand wheel dial and indicator on the front.
Stuffing rings prevent leakage; these consist of alternate grooves and collars in shaft and bearing, like the grooves in an indicator piston.
The switch proper is placed on the rear of the board with hand wheel, dial, and indicator only on the front side.
A late improvement in this indicator consists in the rotating disc, which, being carried by friction may be moved to the starting point where the raised knobs coincide.
There was no need, for the indicator said, "Empty.
Still her downward speed was less than the rate of the upward draft, for the rate of climb indicator told the frenzied girl that the plane was being lifted fourteen hundred feet per minute.
The active needles of the altimeter and rate of climb indicator were the only visible signs that Will-o'-the-Wisp was moving at all.
By this time the indicator on Will-o'-the-Wisp's altimeter marked a height of between eight and nine thousand feet.
The indicator moves over the line of letters, and indicates the letters of the message, one by one.
He undid his heavy leather coat and fumbled in an inside pocket just as the indicator announced that the wireless was working.

A small goods-office is built at one end, in which is fixed the pedestal and leverindicator of the cart-weighing machine.
The indicator is then swung out of the way, and the piece turned.
This indicator can also be used for "catching" fractional threads.
When the end of this indicator (which is one of a number of types on the market) is brought into contact with the revolving button, the vibration of the pointer I shows how much the button runs out of true.
The indicator is held in the lathe toolpost and the contact point beneath the dial is brought against the work.
The uniformity of the distance x at each end is then tested by placing the mandrel upon the offset centers and rotating it, by hand, with a dial indicator in contact at first one end and then the other.
Indicator used when Cutting Threads] =Indicator or Chasing Dial for Catching Threads.
This indicator has a pointer A the end of which is conical and enters the punch mark.
As the use of the indicator when cutting fractional threads is liable to result in error, it is better to keep the half-nuts in engagement and return the carriage by reversing the lathe.
One of these marks would then be set central with the lathe spindle by using a center test indicator as shown in Fig.
The center test indicator is used for setting a center-punch mark, the position of which corresponds with the center or axis of the hole to be bored, in alignment with the axis of the lathe spindle.
The particularindicator illustrated is of the dial type, any error in the location of the button being shown by a hand over a dial having graduations representing thousandths of an inch.
Arcot fell into step with the planet as it moved about in its orbit, and watched the speed indicator carefully.
Jack craned his neck to look at the depth dial and noted the indicator hand was pointing at seventy-two feet.
Here also was the depth dial and the indicator bands that showed when the ship was going down or ascending again, the figures being marked off in feet on the dial just like a clock.
The hands of the indicator began to spin around and the Dewey, relieved of every pound of ballast, shot upward like a rocket.
In a few minutes the indicator hand pointed to zero and the Monitor's officers realized that now their craft was riding awash with her deck fully exposed.
In case the engine becomes overheated, the indicator will register above 180 degrees Fahr.
If no heat whatever is lost by any cause, the line will be traced over and over again by the indicator pencil, the cooling by expansion doing work precisely equalling the heating by compression.
The first is known as the maximum theoretical efficiency of a perfect engine (represented by the lines in the indicator diagram).
To the uninitiated, indicator cards are considerable of a mystery; to those capable of reading them they form an index relative to the action of any engine.
There are two outlets from the pump, each entering the hollow crank-shaft, and there is a branch from each outlet pipe to a circulation indicator convenient to the operator.
It was intended more especially for importers and exchange brokers, and was furnished at a lower price than the indicator service.
An automatic pressure indicatorhad been devised and put in connection with the main circuits.
The Gould and Fisk crowd had cornered gold, and had run the quotations up faster than the indicator could follow.
He obtained the desired speed and load with a friction brake; also regulator of speed; but waited for an indicator to verify it.
Our first engine compelled the inventing and making of a suitable engine indicator to indicate it--the Tabor.
It was at this juncture that Edison reached New York, and according to his own statement found shelter at night in the battery-room of the Gold Indicator Company, having meantime applied for a position as operator with the Western Union.
The indicator was composed of several wheels; on the circumference of each wheel were the numerals; and one wheel had fractions.
Gold fell to 132, and it took us all night to get the indicator back to that quotation.
The "fraction" drum of the indicator could be driven in either direction, known as the advance and retrograde movements, and was divided and marked in eighths.
I kept this position, made many improvements, devised several stock tickers, until the Gold & Stock Telegraph Company consolidated with the Gold Indicator Company.
The work of Edison on the gold-indicator had thrown him into close relationship with Mr. Franklin L.
One indicator looked upon the Gold Room; the other opened toward the street.
His hand was upon the indicator of the wheat dial of the Board of Trade, and he moved it through as many or as few of the degrees of the circle as he chose.
On the wall overhead, the indicator on the dial was rocking back and forth, like the mast of a ship caught in a monsoon.
On the great dial against the eastern wall the indicator stood--sentinel fashion--at ninety-three.
Above the indicator upon the great dial there seemed to be an invisible, inexplicable magnet that lifted it higher and higher, for all the strenuous efforts of the Bears to drag it down.
Over the Chicago Wheat Pit the hand of the greatindicator stood at seventy-five cents.
The object of Mr. Alexander Taylor's indicator is to measure and show by simple inspection the metacentric height under every condition of loading, and therefore to make known the stability of the vessel.
G M, is then determined either by calculations, or more correctly by experiment, by varying the position of weights of known magnitude, or by the stability indicator itself.
Far below, in the blockhouse, the indicator light on the control panel changed from green to red.
With an anxious eye on his air-speed indicator he gave it a little more throttle, then felt the struts compress as the wheels hit.
At a word from Captain Restronguet the quartermaster set the engine room telegraph indicator to stop; another movement, a gentle hiss betokened the admittance of water into one of the sub-compartments of the vessel.
The submersion indicator pointed to thirty-four feet, a depth that allowed the "Aphrodite" to pass under the keel of the deepest draughted battleship afloat, with five feet to spare.
Then he consulted his compass, put the indicator of his traveling machine to the word "up," and shot swiftly into the air.
The sailors squatted in the loops, and Rob swung the vine over his shoulders and turned the indicator of the traveling machine to "up.
This was the first time he had slept with the indicator at zero.
If I keep on as I am I shall be sure to reach land of some sort, in time, and when I wish to return home I can set the indicator to the northwest and that will take me directly back to Boston.
When he reached a point just above the town he put the indicatorto the zero mark and remained stationary, while he examined the place.
When you have risen as high as you wish, set the indicator to the point of the compass you want to follow and you will be carried by the proper electric force in that direction.
Having slipped away from the Turk and attained a fair altitude, he set the indicator at zero and paused long enough to consult his map and decide what direction it was best for him to take.
He turned the indicator of his traveling machine and immediately rose into the air, followed by a startled exclamation from the President of France.
So much time had been consumed at the desert oasis that he felt he must now hasten if he wished to reach home by Saturday afternoon; so, having quickly come to a decision, he turned the indicator and began a swift flight into the east.
Turning the indicator to the word "up" he found, to his joy and relief, that it would yet obey the influence of the power of repulsion.
He pointed the indicator to the word "down," and at once began dropping through the air.
Rob writhed and groaned at losing his possessions in this way, and while his hands were fastened behind him tried to feel for and touch the indicator of the traveling machine.
He turned the indicator and mounted skyward, to the unbounded amazement of the fishermen, who stared after him with round eyes and wide open mouths.
Pendulum indicators are usually connected up as shown in this figure, except that the bell is generally enclosed in the indicator case.
The Pendulum Indicator we have recently patented is entirely self-contained.
This form of indicator consists usually of a permanent bar magnet pivoted near its centre, so that it can hang vertically between the two poles of an electro-magnet placed at its lower extremity.
We close this chapter with an engraving of a very compact and neat form of dropindicator devised by Messrs.
Or the same thing may be taking place at the junction with the relays or at the indicator cases.
As the pendulum, after performing several oscillations, comes to rest by itself in front of the aperture, this indicator requires no setting.
This vane or card hangs just before the aperture in the indicator frame.
C and C, to the extreme right of the indicator frame, are brought from the same battery to work the indicator and contained relay.
The wind box goes to the player picking up the indicator on top of it who then places it in front of him to mark the seat of East Wind.
He is the one to take charge of the East Wind indicatorand placing the South Wind indicator on top to indicate the South Wind round, hands the box to the original East Wind who now becomes the first East Wind of the South Wind round.
West Wind indicator opposite to East, North Wind to the left and South Wind to the right of him (East).
The players then look at their indicators; the one drawing the East Wind indicator becomes East Wind, and occupies the seat marked by the wind box.
He then arranges the whole lot in a perpendicular straight line in front of them all face downward, placing the box with the wind indicator still on top of it in any order he pleases.
I handed Harold a speed indicator which I had just received, (Fig.
Without suggestion from me he soon held this rubber shoe against the end of the axle of the emery wheel and counted, not thirty-eight, but thirty-six revolutions of the wheel of the speed indicator in one minute.
The Indicator The case of the indicator is built of thin wood--the material of an old cigar box will do--9 in.
Where a large amount of this work is to be done, as in automobile and motorboat repairing, it is necessary to have an indicator to save time.
Illustration: A Simple Pocket Indicator for Finding the Negative Wire in Battery Cable Lines] To use, connect the terminals to the battery lines, and the end of the wire in the solution giving off bubbles is the negative wire.
Illustration: The Indicator Box with Coil, Needle and Scale, as It is Used in Connection with the Anemometer (Fig.
The indicator consists of a strip of paper which will reach around the bottle neck and is divided into 24 equal parts representing hours and half hours.
A cheap indicator for this purpose can be made of a 6-in.
A Polarity Indicator Lines in a cable or the ends of connections at a distance from the battery must be tested to determine the polarity.
By this method, an accidental shifting of the indicator is almost impossible.
These wires should be weather-proof, insulated, attached as shown, and running to and connecting the indicator with the anemometer at NN, Fig.
Hsü Shên uses no fewer than 540 of these indicators, and even when the indicatorto a character is satisfactorily ascertained, it still remains to search through all the characters under that particular group.
The solution is allowed to settle, and the clear liquid decanted into a stoppered bottle labelled "chromate indicator for chlorine.
Add a few drops of the chromate indicatorand continue the addition of the silver nitrate until the yellow colour of the solution becomes permanently tinted red, after shaking.
It is used as an indicator in volumetric silver assaying, and for the separation of iodine from bromine.
Where the finishing-point depends upon the absence of a precipitate and no outside-indicator is used.
An excess of the chromate is required to complete the reaction, so that the point at which an indicator shows the presence of undecomposed chromate cannot be satisfactorily taken as the finish.
Another plan is to have thin blotting-paper, moistened with a solution of the indicator and dried; a drop of the solution to be tested placed on this shows the characteristic change.
