This is made as follows:-- Chromic acid 1 gramme 45 grains.
The velocity and hence the current of the Gramme machine can be regulated, and so the action of the brakes.
The engineers, however, seem to prefer that the current be obtained by means of a small Gramme machine, driven direct by a Brotherhood three-cylinder engine, the steam for which is obtained from the locomotive.
In the water thus prepared he completely submerges a 20 grammeflask containing 15 grammes of the oil to be tested.
In short, thanks to the rubber, M, we have an ordinary Gramme collector in that portion of the circuit comprised between the brushes, and a collector with a breakage of the circuit in the portion to the right.
Compared with the Gramme machine, from an absolutely theoretical point of view, the Pfaundler apparatus presents undoubted advantages.
The first solution was thought of by Gramme in 1871, and is represented diagramatically in Fig.
At all events, it is probable that the system has grown old since Gramme invented his collector.
We may figure the apparatus to our mind very well if we suppose that in the Gramme ring a half and almost two-thirds of the core are removed, and the spirals are movable around the said core.
In the application of the Kravogl motor to the generation of continuous currents, Professor Pfaundler now proposes to ingeniously utilize the Gramme collector.
It is of slight consequence whether Gramme knew of this experiment or not, for the glory that attaches to his name could not be diminished for all that.
The ferrocyanide solution is standardized by dissolving 1 gramme of pure zinc in 6 cc.
One gramme of the ore is treated in a flask with a mixture of nitric and sulphuric acids and evaporated until all the nitric acid is expelled.
One gramme of ore is usually taken for assay and treated in a small flask or beaker with 10 cc.
Seven grammes of an impure muddy sediment-leaving spring water containing half a gramme of native sulphate of zinc containing iron.
A mixture of 16 grammes glycerine, 8 grammes hyposulphite of soda, 1 gramme sugar of lead (or an equivalent quantity of Liq.
Per | 1 gramme | of energy, or Name of Substance | cent.
The solution of lecithin employed for this purpose should be prepared by dissolving 1 gramme of lecithin in 100 grammes of pure methylic alcohol.
When cerium nitrate is converted by heat into cerium oxide, the expansion which takes place is practically nil, the ceria obtained from a gramme of the nitrate occupying about the same space as the original nitrate.
Staite patented a process for manufacturing carbons for this purpose, but only after the invention of the Gramme dynamo in 1870 any great demand arose for them.
The rotation is effected by means of a small Gramme motor on a vertical axis, fitted with a speed governor, and supplied with current from a battery of primary cells.
Fontaine states that Gramme had previously told him that he had done the same thing with his machines.
It is advisable to procure a set of gramme weights and to get accustomed to them, which is not by any means difficult.
Accordingly he built himself Gramme bipolars, four polar machines and a Gramme alternation to supply current for Gablacoff candles.
In order not to multiply the solutions, take the ordinary chloride of gold, used for fixing the impressions, and which is composed of 1 gramme of chloride of gold and 50 grains of hyposulphate of soda, to a quart of distilled water.
The Gramme machine, for example, which ignites the Jablochkoff candles on the Thames Embankment and at the Holborn Viaduct, delivers four currents, each passing through its own circuit.
Gramme to the construction of his beautiful machine.
The Siemens and the Gramme machines delivered direct currents, while those of Holmes and the Alliance Company delivered alternating currents.
Wilde's principle, it may be added, is also applied on the Thames Embankment and the Holborn Viaduct; a small Gramme machine being used in each case to excite the electro-magnets of the large one.
They prove the great superiority both of the Gramme machine and of the small Siemens machine over the Alliance.
Gramme subsequently so modified his machine as to produce alternating currents.
One gramme of clean mastic is dissolved in eighty-seven grammes of absolute alcohol, and the transparent solution is allowed to drop into a beaker containing clear water, kept briskly stirred.
One of the machines there experimented with was a Gramme dynamo, used as a motor.
The results I have already given for egg-albumin tend to show that 1 gramme of pure albumin, free from inorganic salts, when dissolved in a moderate amount of water will combine with about 30 c.
This, as has been previously stated, was found to be the case, and Drechsel obtained from ten grammes of a double salt of lysatin and silver one gramme of urea nitrate, by simple boiling with baryta water.
To separate 1 gramme of salt requires the performance of work PV against the osmotic pressure P, where V is the corresponding diminution in the volume of the solution.
An equivalent gramme molecule is a weight in grammes equal numerically to the chemical equivalent of the salt.
Thomson calculates that, allowing only one electron to each atom in a gramme of hydrogen, the tiny globule of gas will contain as much energy as would be obtained by burning thirty-five tons of coal.
In the same epochal year that ushered in the Franco-Prussian War and the Gramme machine, the Hyatts invented celluloid.
Coming as it did so soon after the invention of the Gramme dynamo, it waked the minds of men with a sudden start, and opened a dazzling avenue of anticipation of discoveries and inventions yet to come.
Such is the large volume of oxygen necessary for the development of one gramme of yeast when the plant can assimilate this gas after the manner of an ordinary fungus.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "gramme" in a variety of sentences. We hope that you will now be able to make sentences using this word.
