Title: Improvements in or relating to the introduction and removal of granular solid materials into or from closed chambers at increased pressure
IPC: C10J3/50
Filed: 1950-10-31
Abstract: 699,747. Pneumatic conveyers; screw conveyers; step-by-step conveyers; hoppers. KOPPERS, GES., H. Oct. 31, 1950 [Oct, 31, 1949], No. 26563/50. Class 78 (i). In apparatus for transferring finely divided solid material, e.g. fuel, from a chamber at relatively low pressure to a chamber at higher pressure, the chambers are connected by a channel-like passage in which there is formed, by compression of the material, a gas impermeable sealing plug which preferably is pressed against a resistance member arranged at the high pressure end of the channel, the compressed material on or after transfer into the high pressure chamber being divided finely by a grinding device. The lower pressure chamber 4, Fig. 1, is connected to the high pressure chamber 10 by a cylindrical passage 5 which is constricted at 7. A.piston 6, which is reciprocated in the part 5 by a crank 8 and connecting rod 9, compresses the material therein into a plug and simultaneously discharges a part of the material from the constriction 7 into the chamber 10. The material may be compressed more than once. In a modification the material is forced by a worm 28, Fig. 2, into the constriction 32 leading to the high pressure chamber 33 and against a rotary grinding head 35, the shaft 36 of which is yieldably supported, e.g. by steel springs 41. Carrier gas is admitted at high pressure through approximately tangential nozzles into the enlargement 48 and conveys material through a branch 34 to a conduit. Another modification, Fig. 3, is designed for use with a receiving chamber under very high pressure. In this construction the material is fed and compressed by a reciprocating plunger 61 mounted in a yoke 62 which is reciprocated by cranks 66. The grinding head 73 is resiliently mounted as before. Powdered material falls from the chamber 75 through the pipe 86 into the chamber 87 from which it is forced by the worm 88 into the blast apparatus 89. In a further modification, Fig. 4, material from the hopper 115 falls on to a rotatable plate 117 from which it is swept by a plough 125 into a pipe 127 connected to the passage 105 in which the reciprocating plunger 106 works. The pressure to which the material is subjected is varied by adjusting the position of the pin 129. Material passes from the compression chamber 105 into the chamber 132 containing a rotary grinder 133, the ribs or teeth of which co-operate with ribs 135 on the walls. From this chamber material is forced by gas supplied by nozzles 146 through an annular passage between a pear-shaped member. 145 below and rotating with the grinder.

Title: Improvements in the production of composite metal articles
IPC: B22F1/17
Filed: 1936-02-14
Abstract: 463,775. Making composite plates and bearings. HARDY METALLURGICAL CO. Feb. 14, 1936, No. 26565. Convention date, Sept. 24, 1935. Divided out of 459,336. [Classes 83 (ii) and 83 (iv)] Soldering; welding.-A coherent mass formed by compressing and heating metal powder particles having cores of a metal of relatively low melting point, and coatings of a metal of a higher melting point and which does not alloy readily with the metal of the core in all proportions, as claimed in Specification 459,336, is secured to a metal backing by subjecting the backing and the coherent mass to pressure and to a temperature lying between the melting points of the core and coating metals. In the manufacture of a composite bearing a coherent mass of particles of lead coated with copper is produced as described in Specification 459,336 and is compressed in contact with a cleaned backing of steel, copper, or bronze at a temperature between the melting points of lead and copper (327 to 1083 C.) in an atmosphere of hydrogen. Alternatively, the sheet is rolled under slight pressure on a copper or bronze backing sheet previously roughened by electroplating, sand-blasting, or by fusing on a thin layer of coarse copper powder, after which the assembly is heated at a temperature lying between the melting points of lead and copper. The backing layer may be tinned. A steel backing is cleaned and dipped in molten tin, and heated to above 450 C. in a reducing atmosphere in contact with the copper-lead coherent mass. In a modification the tinned backing sheet is heated to 450 C. in hydrogen, and the other layer is then applied. To facilitate welding by diffusion, a thin layer of copper powder may be placed in the mould in which the coherent mass is initially formed by sintering, the copper coating so formed being placed in contact with the backing sheet in the welding operation. Specification 441,177, [Group II], also is referred to.

Title: Ball bearing testing device
IPC: G01M13/04
Filed: 1956-09-06
Abstract: 812,194. Photo-electric testing of ball bearings. BENDIX AVIATION CORPORATION. Sept. 6, 1956 [Sept. 7, 1955], No. 27361/56. Class 40 (3). The starting or " break-away " torque of a ball-bearing assembly is measured a predetermined number of times by a photo-sensitive device and counter circuit coupled thereto. Vanes or buckets 46 on the rotor 40 of the test bearing 45 are driven by air passing through a motorized valve 21 and a nozzle 47. A scanning  disc 44 mounted on the rotor interrupts a light beam passing to photo-electric tube 49. The pulsed signal is received by a pulse amplifier 23 and passed to a pulse counter 26, a pass relay 27, a cycle counter 28 and a green light 66, as well as to a pulse interval detector 24, a motor relay 23 and the motorized air valve 21. As shown in Fig. 4, the stem 61 and the slotted lining 60, 70 are driven by motor 50 through gearing 19 and against the spring 71 so that progressively varying amounts of air are fed through. Control is exercised by two limit switches 52<SP>1</SP>, 53 set for 50 degrees and 150 degrees of rotation, and by clutch 51 which engages planetary carrier 19. In testing a bearing, start button 76 is actuated and clutch 79 is energized and held and the cycle counter 28 is set. The air-valve clutch 51 and motor 52 are energized and controlled air passes to the nozzle 47 rotating the buckets carried by the bearing after overcoming the break-away friction. The pulses generated by the scanning disc are amplified and passe d to the counter 26 and to pulse interval detector 24. The counted pulses charge a condenser to a point where pass relay 27 operates and doenergizes the clutch 51 of the air valve. If the pulse intervals are correct, the charge on condenser 102 is maintained. When the bearing has stopped, the relay 25 is de-energized, closing contacts 105, 106 and restarting the motor 50 and the operating clutch 51 to initiate another cycle for the bearing. When the cycle counter 28 receives the last pulse it is designed to count, clutch mechanism 79 is released cutting off the motor 50 and energizing a green light. If the bearing is faulty and its break-away friction too high, it does not rotate when the air from nozzle 47 is applied and a pressure-sensitive diaphragm 115 expands moving a needle 116 until it reaches a reject point where contacts 118, 119 close energizing a reject relay 29 and a red lamp 120 and restoring all circuits to starting position. A safety relay 30 in the filament supply circuit also returns circuit conditions to starting and energizes an amber lamp. Air pressure failure operating limit switch 53 also de-energizes the safety relay 30. Switch 18 enables the motorized air valve motor to be maintained in operation for calibration of the maximum starting torque conditions.
