There are two diaphragms of gauze in the burner head to prevent firing back, and one in the nozzle portion of the burner.
Sound waves constantly vibrate such diaphragmsas panes of windows and the walls of houses.
The vibration of one of the diaphragms changes the potential of the other pair; the degree of attraction thus is varied, so that vibration of the diaphragm and sound waves result.
The two diaphragmsof each instrument are kept drawn towards each other because their unlike charges attract each other.
Vibration of Diaphragms:--Sound waves in air have the power to move other diaphragms than that of the ear.
The diaphragms became thin iron disks, instead of membranes carrying iron; the electromagnet cores were made of permanently magnetized steel instead of temporarily magnetized soft iron, and the battery was omitted from the line.
It consisted of elasticdiaphragms on steel frames attached to the ends of the cars, the faces of the diaphragms when the train was made up, pressing firmly against each other by powerful spiral springs which held them in position.
These tongues are firmly inserted in the diaphragms and fixed to the magnet, as shown.
The number of diaphragms required is always one less than the degree of multiplicity of the continuity.
In proof of this view, it is cited that diaphragms much too rigid, or charged with irregularly distributed masses over the surface, or pierced with holes, or otherwise evidently unfitted for the purpose, are available for transmission.
Corrugated iron was used for the diaphragms instead of sheet iron as it was more easily maintained in a vertical position.
The purpose of thesediaphragms was to provide weak sections in the walls, so that if there was any tendency to crack it would occur along the line of the diaphragms.
The results obtained by using diaphragms have been quite satisfactory, and cracks approximately straight and vertical have usually appeared opposite the diaphragms soon after the forms were removed.
An effort to control the cracks was made by placing corrugated-iron diaphragms in the form, dividing each 50-ft.
Inside of concrete form for lower-face wall, showing drains, tie rods, diaphragms and methods employed for tying in the form in addition to braces outside.
The concrete was mixed wet, and was not rammed; the stone was spaded back from the face, and no facing mixture or facing diaphragms were used.
No facing mixture or facing diaphragms were used, but the stone was spaded away from the face of the wall as the concrete was laid.
Tom had rigged up a jointed, clawlike mechanical arrangement with sensitive diaphragms in its "finger tips.
The diaphragms were connected to a transistorized circuit designed to modulate the field current to the electromagnets.
There it is caused to spread by muslin or felt diaphragms so that no perceptible current of air strikes the eggs.
When sound-waves struck these hemispheres, the diaphragms would respond.
It consisted of a lot of tiny diaphragms set in a big hemisphere.
All these various diaphragms fall or recede for inspiration, rise or advance for expiration; the function of a diaphragm being exercised in conformity with the manner in which it is approached.
The gas from this pipe comes into the valve chamber and passes alternately into the diaphragms and their chambers, as the valve ports V are opened and closed by the action of the meter.
While the meter is in operation, one of the diaphragms and one of the case compartments are filling while the others are emptying.
Stipitate; valves with transverse puncta, bent along the transverse axis, cuneate, with diaphragms at the ends.
Forms like Stauroneis but with diaphragmsat the ends.
In telephone receivers we may employ disks or diaphragms of any thickness up to six inches (Bell, Breguet, and others).
In diaphragms of sufficient thickness this kind of motion would exist alone.
We can go still further, and employ diaphragms of scarcely any stiffness and elasticity without altering their essential telephonic properties, the reproduction of a continuous series of sounds, accords, and timbres.
The various types of diaphragm cells that have been commercially operated are of two varieties: (1) cells with submerged diaphragms and (2) cells in which the electrolyte comes in contact with one face only of an unsubmerged diaphragm.
As my grip upon him made audiphone contact, his agonized scream rattled the diaphragms of my ear grids with horrible, deafening intensity.
Diaphragms can be placed across either extremity, or at various sections, to confine the mixtures of gas and air in which the tests are made.
These paper diaphragms are used to assist in confining a gas-and-air mixture.
The commander had before him a bewildering array of controls, while near his ears were the diaphragms that, by their buzzing sound, would give telephonic warning of any obstruction.
But the diaphragms acted over a wider area than the lamp, the beams of which were necessarily dimmed by the density of the water.
This sectional drainage is effected by dividing the interior into diaphragmssomewhat inclined to the horizontal, so that the water of condensation is removed as fast as formed and does not flow from the upper tubes over those beneath.
The headers are usually of malleable cast iron with diaphragms cast in them, but sometimes steel has been employed, the bottoms being closed by a riveted steel plate, and the diaphragms being made of the same material.
The contacts consisted of minute hammers resting on metal points fixed to the centre of diaphragms which closed the end of the experimental pipes.
The sound wave was usually originated by firing a pistol into the pipe furnished with diaphragms and contact pieces.
The nozzles in the diaphragms and the intermediates do not, except in the lowest stage, take up the entire circumference, but are proportioned to the progressive expansion of steam as it descends toward the condenser.
Plate diaphragms of full girder depth and particularly stiff were carried right across the bridge at the centre of the spans, and over the piers.
The structure was, as a consequence of the examination, efficiently braced by diaphragms between the ribs, and diagonals following the arch ribs round from springing to springing, with satisfactory results.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "diaphragms" in a variety of sentences. We hope that you will now be able to make sentences using this word.
