Whilst engaged at the Surrey Institution he invented the oxyhydrogen blow-pipe.
He finally developed the "lime-light" by directing an oxyhydrogen flame upon a piece of lime and this device was adapted to search-lights and to indoor projection.
But the best results are obtained from the oxycalcium and oxyhydrogen burners.
When two bags are required (as in the case of the oxyhydrogen light), the double pressure-board (Fig.
Having explained the oxycalcium lamp and jet, we have now to describe the oxyhydrogen jet, by which the brightest form of lime-light is produced.
In the oxyhydrogen jet there is also complete safety if care is taken not to fill up the hydrogen-bag with oxygen, and vice versâ.
The light obtained by the oxycalcium arrangement, although not equal to the oxyhydrogen light, is admirably adapted for exhibitions on a moderate scale, and it requires only one gas-bag.
The lime-holder of the oxyhydrogen jet is made to slide, so as to be capable of being moved towards or away from the point of the jet.
Oxyhydrogen microscope, a form of microscope arranged so as to use the light produced by burning lime or limestone under a current of oxyhydrogen gas.
Defn: Of or pertaining to a mixture of oxygen and hydrogen; as, oxyhydrogen gas.
The oxyhydrogen flame, for example, consists of hot aqueous vapour.
Coke, whether brought to a white heat by the electric current, or by the oxyhydrogen jet, pours out invisible rays with augmented energy, as its light is increased.
It is whiter than iron, harder than silver, infusible in the strongest heat of our furnaces, and melts only when exposed to the highest temperature obtained by Deville's oxyhydrogen gas furnace.
The specific gravity of osmium in the pulverulent form is about 10; but after having been heated to the fusing point of rhodium in the oxyhydrogen jet, it acquires a density of 21.
When perfectly dry, and after having been submitted to a gentle heat, one end of these sticks is brought into the termination of the flame of an oxyhydrogen blowpipe, until a portion of the mass is fused into a small globule.
The anhydrous oxide BaO fuses in the oxyhydrogen flame.
It is infusible in the furnace and even at the temperature of the oxyhydrogen flame.
Alumina itself is so refractory that it cannot be melted save by the oxyhydrogen blowpipe or the electric arc, and except in the molten state it is not susceptible of decomposition by any chemical reagent.
When acetylene was first introduced on a commercial scale attempts were made to utilize its great heat of combustion by using it in conjunction with oxygen in the oxyhydrogen blowpipe.
When the oxyhydrogen lamp is used, the screen is placed ten feet away from the light, and the artist's hands at three feet from the same, and consequently at seven from the screen.
For a small screen theoxyhydrogen light will be sufficient.
A jet of coal gas is insufficient, but the oxyhydrogen light is sufficiently intense.
While the oxyhydrogen flame is intensely hot, it is almost non-luminous.
It has been used also as a source of heat and light in the oxyhydrogen blowpipe.
While the temperature of the flame is not so high as that of the oxyhydrogen blowpipe, it nevertheless suffices for most chemical operations carried out in the laboratory.
Why is oxygen passed through the inner tube of the oxyhydrogen blowpipe rather than the outer?
The oxyhydrogen blowpipe, used to effect this combination, consists of a small tube placed within a larger one, as shown in Fig.
It is insoluble in water and in most chemical reagents, and requires the hottest oxyhydrogen flame for fusion.
Heated intensely, as in theoxyhydrogen flame, it gives a brilliant light called the lime light.
It melts in the oxyhydrogen blowpipe and in the electric furnace; it is harder than gold and is a good conductor of electricity.
During the last great European war in 1932, while three emperors, two kings and several princes were parleying together, a monster oxyhydrogen shell exploded near them and created fearful havoc.
At three minutes to 7 the engineers and conductor come on board; the former to place the powerful oxyhydrogen charge in the great breech-loading tube, the latter to close the doors against ingress or egress.
The only difference between quartz in theoxyhydrogen jet and quartz in the arc is that in the first you make threads and in the second are blown bubbles.
It is possible to make any quantity of very fine quartz fiber without a bow and arrow at all, by simply drawing out a rod of quartz over and over again in a strong oxyhydrogen jet.
To the tail of the arrow is attached a fine rod of quartz which has been melted and drawn out in the oxyhydrogen jet.
This is then allowed to fall through an oxyhydrogen flame.
Another product of the oxyhydrogen flame is the quartz fibres which are used for suspending the needles in the finest galvanometers.
Hotter even than oxyhydrogen is the oxyacetylene flame, which at its hottest point reaches nearly 3500 deg.
The oxyhydrogen jet has been known for many years as the best means of producing the light for a magic lantern.
But the oxyhydrogenjet is now employed in many factories for the welding of metals.
The oxyhydrogen flame has a temperature of about 2000 deg.
Then with a stick of brass wire in the left hand, and an oxyhydrogen blowpipe in the right, we should direct the flame from the pipe on to the metal until, at one point, the sides of the groove were beginning to melt.
The oxyhydrogen light is very hot indeed, the spirit flame with the sodium is comparatively weak and cool.
The lime light is made by directing the jet of an oxyhydrogen blowpipe against a cylinder of lime.
Cheap oxygen would greatly increase the light derivable from oil and gas, as proved in the brilliancy of an oxyhydrogen jet.
We have found that articulate speech can be reproduced by the oxyhydrogen light, and even by a beam from a kerosene lamp.
Winn, of Truro, has suggested that the oxyhydrogen lamp may be made subservient to horticulture in the dark days of winter.
The oxyhydrogenflame that burns the diamond and volatilizes platinum; then came the Drummond lime-light that is visible as a star sixty miles away; now followed Dobereiner’s lamp that ignites itself when you lift a latch.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "oxyhydrogen" in a variety of sentences. We hope that you will now be able to make sentences using this word.
