Abstract: 222,856. Elektrizitats - Akt. - Ges. vorm. Schuckert & Co., (Assignees of Petz, F.). Oct. 3, 1923, [Convention date]. Cells; diaphragms; electrodes; hydrogen and oxygen, obtaining.-In a cell having walls of cement or like resistant material with which the electrodes are in contact, one or more metal layers are embedded in the walls in the zone between adjacent electrodes. The metal insertions are stated to diminish leakage of current through the walls by their polarizing action. In one form, Fig. 1, bipolar electrodes e<1> .. e<3> and diaphragms d<1> .. d<2> set in metal frames r<1>, r<2> are fitted closely in grooves t in the wall T and iron plates z<1>, z<2> extend from the bottom of the diaphragm grooves to the opposite side of the wall. In a modification the iron plates are situated between the electrodes and the diaphragms and are provided with flanges at the inner end extending nearly to the adjacent electrode and diaphragm. Each diaphragm man be connected to one but only one plate. In another modification, the metallic insertions comprise a set of channel plates z<9> - - z<14>, Fig. 3, whose flanges enter the recesses of a second set of channel plates z<15> - - z<19>, without making contact therewith. The plates may be rolled or bent from sheet metal. In a cell for generating oxygen and hydrogen by electrolysis of hot lye, the bottom 1, Fig. 4, and the side walls are made in the manner described; the end walls S<3>, S<4> are of sheet iron and are welded to the outermost embedded plates of the other walls. The side walls are provided with vertical grooves adjoining those in the bottom into which the electrodes fit. End electrodes e<4>, e<5> may be provided or the walls S<3>, S<4> may serve as such. Gas collecting bells g rest on cornices a, b at the top of the electrodes and diaphragms respectively. The cornices are covered with yielding insulating material such as asbestos fabric. Spaces f open to the atmosphere are left between the gas-bells g. The bells are connected alternately by pipes having flanged connections to two manifolds h<1>, h<2>. Insulators i are inserted between adjacent sections of the manifolds. The bells may be of insulating material or of metal; in the, latter case they function as polarizing electrodes in the same manner as the insertions in the walls. The joints between the bells and the side walls of the tank may be packed and the bells brought into contact with the adjacent embedded plates. Perforated metal sheets n are welded to the working ,electrodes,. The electrodes may be dished as shown at e<6> to provide a cathode chamber approximately twice the volume of the anode chamber. The same result may be obtained by using ordinary electrodes with Z frames or by suitable spacing of the grooves receiving the electrodes and diaphragms.

Title: An improved synthesis of hydrocarbons
IPC: C07C1/04
Filed: 1946-07-29
Abstract: In the synthesis of hydrocarbons from carbon monoxide and hydrogen using a fluidized catalyst, steam is added to assist in suspending the catalyst whereby a higher ratio of catalyst to synthesis gases may be maintained.  Synthesis gas produced at high temperature, for example from methane and steam, may be cooled to the synthesis temperature, say, 400-600 DEG  F., by introducing a water spray, thereby producing the steam.  Methane, steam and CO2 in a ratio 1 : 1.6 : 0.7 are passed through a nickel-kaolin-magnesia catalyst at 1500 DEG  F. and a pressure up to 200 p.s.i. to give a 1 : 2 mixture of CO : H2.  Water is injected into the exit line and the cooled gases, into which a catalyst of cobalt-kieselguhr-thoria of 50-400 mesh is fed from a standpipe provided with gas taps for injection of steam, pass to the synthesis chamber.  Reactants flow upwardly at 1/2 -5 ft./sec. to maintain a fluidized state.

Filed: 1925-09-12
Abstract: 240,153. Archaouloff, V. Sept. 17, 1924, [Convention date]. Cylinders receiving liquid fuel. -To prevent formation of carbon around the spraying orifices 2 of a fuel injector, an air pocket 6 is formed between the injection valve 4 and orifices 2, such that during the compression and expansion strokes air will be forced to or from this pocket through the spraying orifices. The passage 5 leading from the injection valve 4 projects below the level of the orifices 2, except in nozzles so small that capillarity will suffice to retain the oil in the passage 5 between the injections. During the period of injection, the air in the chamber 6 is highly compressed by the fuel, which rises above the level of the orifices. After the closing of the valve 4, injection continues until the excess fuel has been discharged and the orifices are again uncovered and scavenged. The invention may be applied to an injector intended to be used in a horizontal position bv forming the outlet from the passage 5 in the side of the projection x.

Abstract: 543,386. Fuze-setting apparatus. MEFINA SOC. ANON. Aug. 8, 1939, No. 22901. Convention date, Feb. 10, 1939. [Classes 9 (i) and 92 (ii)] " Loading time " elapsing between the removal of a projectile having a clockwork fuze from the fuze-setter and the firing of the gun is provided for in an apparatus in which the gun is fired automatically when two motor - controlled electric-contacts meet, one contact being moved in register with the running-down of the fuze and the other contact being controlled by the predictor. The fuze-setter A is adjusted by two handles B, C, differential D and worm gear F. The handle B is used for the basic setting in accordance with the indication given by a predictor-controlled pointer H. The handle C is used to apply a correction for "loading-time" and if necessary for movement of target to or from the gun site. The fuze-setter spindle E is also geared by gears K, K<SP>1</SP> to a sleeve L carrying a pawl N which engages an abutment O on the drum P of a friction clutch. The drum carries one of the two motor-controlled contacts R. The second contact S is driven by a motor J<SP>1</SP> under control of the predictor. When the shell Z is withdrawn from the fuze-setter A, its clockwork commences to run and simultaneously the fuze-setter, through levers U, U' slides a sleeve V on the hollow shaft L and rocks the pawl N out of engagement with the abutment O. This permits a motor M, synchronized with the working of the time fuze, to drive the drum P and rotate the contact R in the path of the contact S. The contacts R, S meet when the instantaneous fuze-time agrees with the predictor indication, and the gun-firing circuit T is then closed and the gun fired automatically.

[Class 103 (i)] Release valve for automatic vacuum brakes in which a valve 20 controlled by a diaphragm 17 influenced by the vacuum in the train pipe 36 and in the lower chamber 11 of the brake cylinder and adapted, on release of the brakes, to connect the lower chamber of the brake cylinder to a vacuum reservoir connected to a chamber 19, comprises a non-return valve 26 between the train pipe chamber 12 and the chamber 19 which isolates the train pipe from the lower chamber of the brake cylinder and the vacuum release reservoir during brake release. On brake application, the increased pressure in the train pipe transmitted through passage 15 to the chamber 12 depresses the diaphragm 17 controlling the valve 20 and closes this valve. When the train pipe pressure is reduced on release of the brakes, the valve 20 reopens to connect the lower chamber 11 to the vacuum reservoir. The consequent reduced pressure below the diaphragm recloses the valve and by a series of train pipe pressure reductions a graduated release is obtained. The lower chamber 11 and the vacuum reservoir are completely evacuated past the check valve 26. The release valve is combined with a graduated application valve 6 which is raised by increase in train pipe pressure below a diaphragm 13 to admit atmospheric air through an air strainer 4 to the chamber 11. The consequent increased pressure above the diaphragm 13 recloses the valve and by a series of train pipe pressure increases, a graduated application is obtained.
