IPC: F04B39/02
Filed: 1919-04-07
Abstract: 125,586. Bruand, E. April 13, 1918, [Convention date]. Pump-actuating mechanism; valves, arrangement of; heat of compression, absorbing; regulating compression.-In an air-compressor comprising. a doubleacting piston containing the crank of a driving crankshaft and a rod connecting the crank to one end of the piston, a single cam-actuated inlet valve and an automatic outlet valve are provided at each end of the cylinder, the inlet valves being held open during compression when the pressure in the reservoir reaches a certain value. As shown, the cylinder is cast in one with a metal base, and provided with removable end covers carrying the inlet and outlet valves b<1>, b<2>, c<1>, c<2>, Fig. 4. The piston comprises heads d<1>, d<2>, connected by a member d of smaller diameter formed with openings d<4>, Fig. 4, and d<5>, Fig. 5, the driving-shaft passes through a bearing e<2> in the opening d<5> and is formed with a crank within the piston connected by a rod f to its head d<2>. The air entering by a port h<1> passes through a space h<2> between the base and its support, and through channels h to the inlet valves. These are disk valves closed by springs and opened at intervals by levers operated through rods k<1>, k<2>, Fig. 6, which are actuated through rollers k<3> on their other ends by a cam l on the shaft e. A second cam m on the same shaft acts on rollers n, the spindles of which move in grooves in a rocking plate o<2> which is acted on by a piston p, subject to the receiver pressure when the latter reaches its maximum, so as to turn the plate into a position where the rollers n are interposed between the rollers k<3> and the cam m. In this position, the inlet valves are held open during the compression strokes except for a slight interval at the end of the stroke which provides for cushioning. When the receiver pressure drops, the plate o<2> is retracted by springs, the air behind the piston being allowed to escape to atmosphere. Cooling is effected by water chambers w, w<1> in the sides and end covers of the cylinder. Lubricating-oil is contained under pressure in a reservoir x above the cylinder, connected with the left-hand compression chamber through a passage 1 provided with a regulating- screw 5 and a non-return valve 2. Passages leading through external glass tubes lead the oil to the ends of the cylinders and to the bearing e<2> of the driving-shaft. Excess oil passing to the bottom of the cylinder is led through a passage 16 to a pump 10, Fig. 6, the piston of which is mounted on the rod k<2>, and forced back to the reservoir. The cover of the reservoir is secured by screw plugs y on one of which a gauge 14 may be provided. The cylinder may be divided, leaving a space in the middle permitting a longer stroke. The ends of the cylinder may be of different dimensions.

Title: Improvements in or relating to cathode ray devices
IPC: H01J31/12
Filed: 1939-03-20
Abstract: 526,534. Cathode-ray tubes. ELECTRICAL RESEARCH PRODUCTS, Inc. March 20, 1939, No. 8774. Convention date, March 31, 1938. [Class 39 (i)] A primary beam of electrons A moves to-andfro along a linear path on a target 12 emitting secondary electrons B which are accelerated by an electrode 63 and pass through an opening C therein parallel to this path and scan an adjacent fluorescent screen 61 along a corresponding linear path. The light from the screen 61 may emerge as shown coaxially with the axis of the multi-anode gun producing the beam A, the target 12 and electrode 63 being inclined to this axis. In modifications the target 12 is on this axis and inclined and emits secondary electrons to a lateral fluorescent strip which may emit light through a slot in the accelerating electrode 63 or may be in or on the wall of the tube. The electrode 63 may be spaced from the fluorescent strip or formed as a metal cover or coating on the fluorescent material which may be on a glass support. Electrodes 13 operated in push-pull or one at a fixed potential deflect the beam A to scan the linear path and a magnetic field 51 brings this path to a correct place on the target 12. In a television transmitter, a lens 18 focuses the light through a film moved continuously or in steps on to a photo-electric cell. The light may be modulated by deflecting the beam A laterally of the linear path on the target by a second pair of deflecting plates, the beam B being thus laterally displaced and so axially cut off either at the side of the opening C or at a slotted cover on the fluorescent strip. The modulated light may be focused on to a moving film to make a track record or may be transversely moved as by mirrors to project an image on a screen.

Abstract: 271,422. Rihosek, J., Leuchter, R. L., and Hardy Maschinenfabrik und Giesserei Akt.-Ges. May 19, 1926. [Convention date]. Addition to 260,250. Fluid-pressure.-In valve mechanism for effecting the graduated release of single chamber fluid pressure brake apparatus as described in the parent Specification, the auxiliary device for cutting off the release valve. from the train-pipe during the application of the brakes is adapted also to cut off the main control valve from the train-pipe during the release of the brakes. The main control valve comprises a piston 31 operating a slide valve 34 under the control of the pressure in the train-pipe 30 and that in the auxiliary reservoir 39 which is supplied from the train-pipe through the passage 32. The release valve comprises a piston 7 connected to the brake cylinder exhaust valve 10 and subject to the opposing pressures in the auxiliary reservoir 39 and a chamber 12. The auxiliary valve comprises a piston 19 connected directly to a valve 21 and by means of a spring 51 to a valve 52 disposed in a chamber 13 which is connected by the pipe 14 to the train-pipe 30. The chambers above and below the piston 19 are connected respectively to the atmosphere by port 17 and to a port in the seat of the main control valve 34 by the pipe 15. A passage 54 with a non-return valve 55 may also be provided in the casing of the auxiliary valve. In running conditions as shown in Fig. 1, the valve 52 is open and the train-pipe 30 is connected through the chamber 13 to the piston chamber of the main valve 34 so that the brake cylinder 38 is open to atmosphere through the main valve 34, the passage 53 in the piston chamber of the auxiliary valve and port 17. The chamber 12 of the release valve is cut off from the train-pipe by the valve 21. A step-by-step application of the brakes may be effected by sucaessive reductions of the train-pipe pressure whereby the brake cylinder is connected to the auxiliary reservoir by the main valve 34 and graduating valve 56 in the known manner. If the train-pipe pressure is thus raised the valve 34 connects the brake cylinder to the chamber of the piston 19 of the auxiliary valve which is thus raised to close the valve 52 and open the valve 21. The train-pipe pressure acting on the piston 7 of the release valve then opens the valve 10 and the brake cylinder exhausts through the port 3 until this pressure has equalized with that in the auxiliary reservoir through a passage 5 past the piston 7 when the exhaust valve 10 is again closed. A step-by-step reduction of the brake cylinder pressure may thus be obtained until this pressure has fallen sufficiently to enable the trainpipe pressure acting in the valve 21 to return the piston 19 and permit further exhaust through the port 17, If the train-pipe pressure is reduced after a releasing step, the valves 52 and 55 open to transmit the pressure reduction to the chamber of the main valve and effect a further application of the brakes.
