Granted: 1898-01-22
Abstract: 6651. Hargreaves, J. R. March 13. Gas and like engines, cylinders for. The m a i n cylinder A is made with as small a clearance space as possible, so that the spent gases are entirely swept out in the exhaust stroke. An auxiliary cylinder C mounted on the main cylinder receives the compressed charge at the end of the compression-stroke, but during the exhaust and suction strokes its piston D, which is weighted or held down by springs, occupies its lowest position as shown. Air is admitted freely into the upper end of the cylinder C through a valve E which leaves only a small aperture for the exit of air, so as to produce a cushioning effect on the piston D when the latter is forced up by the compression-stroke of the main piston. Springs F, F<1> prevent knocking.

Granted: 1900-12-08
Abstract: 1457. Barnes, W. Jan. 23. Chlorine.-The compartments of an electrolytic apparatus are placed in connection with a vacuum apparatus, so that the gases evolved are withdrawn rapidly, and polarization is prevented. In the form of apparatus shown, which is suitable for electrolysing saline solutions, such as ammonium chloride, the salt is placed in a feeding-reservoir A, which is provided with rotating mixing-arms a, and is led from it by a tube a<6>, having regulating-taps a<7> which continuously drop the solution to intermediate reservoirs A<1>, one for the cathode, and the other for the anode compartment of the cell, which is closed airtight. From the reservoirs A' the liquid flows to closed automaticfeed regulators B, through pipes b having an insulating section b<1> and a thermometer b<2>. The regulators have float valves b<9> and mains b<3> with side branches leading to the corresponding anode B<3> or cathode compartment B<4>. The cell is divided into these compartments by a diaphragm porous in its lower portion, and is provided with an anode b<11> and a cathode connected up to a dynamo &c. C. The cover is formed in sections b<21>, with a rubber layer b<22> between each pair of sections, and also between the cover and the sides. The cover is secured by swinging bolts b<25>. The cell is supported upon insulators I. Each compartment is provided with a gauge glass b<5> and a liquid draw-off pipe f, having an insulating-section f and leading to tanks F, F<1>, from which the liquid can be led to a single stand-pipe f<12> arranged for testing purposes, and thence forced by a pump to an auxiliary reservoir A<2>, where it may be further treated, and fed back to the feeding- reservoir A. The anode compartment B<3>, the automatic-feed regulator B, and the tank F for the liquid from the anode compartment are all connected to an exhaust main d' leading to an exhaust pump D, from which the gas, such as chlorine, evolved in the process may be led by a tube D<2> away for storage or use. Similarly, the parts B', B, and F<1>, on the cathode side, are connected to the exhaust main d<7> and pump D', having an outlet d<2> for gas, such as ammonia. Suitable cocks, pressure gauges, &c. are provided as indicated. On a commercial scale, a large number of cells may be used, all the anode compartments being connected to one regulator and exhaust, and all the cathode compartments to another. If no gas is evolved from one of the compartments, that one need not be connected with a vacuum apparatus. Some modifications are described and illustrated. In one, the cell is divided into an inner (anode) compartment, and outer (cathode) compartment. In another, one or both of the electrodes may be a hollow perforated rotary cylinder, while in a third the electrodes are blocks carried from a cross-bar. In another form, the compartments are separated by a non-porous plate extending from the top of the cell so as just to dip into the electrolyte.
