Patent GB-531453-A (GB)
Title: Improvements in and relating to control means for air or gas compressors
IPC: F04B49/02
Filed: 1939-07-24
Abstract: 531,453. Fluid-pressure servomotors. ADAMSON & CO., Ltd., D., and SLOAN, D. T. July 24, 1939, No. 21403. [Class 135] A governing device for an air or gas compressor driven by a prime mover is adapted to prevent overspeeding of such compressors when under light load. The inlet valve 6 of the compressor is controlled by a piston rod 9 attached to a piston 7 in a cylinder 8 fitted with an oil inlet 10 for admitting oil at a constant pressure which tends to raise the piston 7 and valve 6 to dotted line positions in which the valve 6 is fully open and the compressor working under load. When no load is on the piston tends to drop to its lowest position and the valve 6 is then closed. The cylinder 8 is fitted with apertures 11, 12 connected by valves 13. 14, Fig. 2, respectively, to a source of air supply and to an oil outlet, so that when the valves 13, 14 are opened the piston 7 assumes an intermediate position in which the valve 6 is partially closed, and in this position ventopenings 25 on a member attached to the rod 9 are at such a level that air from a chamber 26 connected to the high pressure chamber can escape to atmosphere, whereas when the rod 9 is fully raised the openings 15 are cut off from the atmosphere. The valves 13, 14 are operated by a lever 16 when this is depressed by a cam 19 on a spring-controlled shaft 26. This shaft is normally prevented from rotating clockwise under the action of its spring by engagement of the end of the lever 16 with a stop 18 on the cam 19. The cam 19 may be brought into action by an emergency centrifugal governor which depresses the lever 16 when the compressor overspeeds when off-loaded, or the cam may be hand-actuated by rotating the shaft 26 counter-clockwise. A stop 23 on a lever 22 holds the cam in its depressed position until the apparatus is properly reset.
Patent GB-290081-A (GB)
Title: Improvements in tractors
IPC: B62D11/08
Filed: 1927-08-15
Abstract: 290,081. Marks, E. C. R., (Harnischfeger Corporation). Aug. 15, 1927. Gearing for stopping and starting machinery. - Clutches and brakes for driving and steering a tractor are actuated by a single cam means adapted to (1) apply both clutches and release both brakes, (2) release both clutches and apply both brakes, or (3) apply either clutch and the opposite brake. A power shaft 2 carries two pinions 3 which can be clutched to the shaft so as to drive gear wheels 5 on shafts 7 carrying sprocket wheels driving endless tracks 10. Each gear wheel 3 can be connected to the shaft 2 by a clutch 33 and can be held, when disconnected, by a brake 64 the clutch and brake being operated in succession by a lever 60 mounted on a shaft 42. The two levers 60 corresponding to the two tracks carry rollers 61, 81, working in a common groove 62, formed in a gear wheel 63 which can be rotated when desired by a hand-wheel and pinion 87 carried by the turntable. The pinion is normally not in mesh with the wheel 63, so that rotation of the turntable does not affect the clutches and brakes. In the position shown in Fig. 15, the rollers 61, 81 are at their maximum distance from the turntable centre, both clutches are disengaged, and both brakes are applied. In this position a stop 90 in the cam groove bears against the roller 81 which thus prevents further rotation of the cam wheel 63 in the clockwise direction. On rotation of the wheel in the counterclockwise direction the following operations occur successively :-(1) The right-hand brake is released and its clutch is engaged, the left-hand side being unaffected, so that the righthand track alone is driven and the tractor steers to the left, (2) the right-hand clutch remains engaged, the left-hand brake is released, and its clutch is engaged, so that both tracks are driven and the tractor moves in a straight line, and (3) the right-hand clutch is disengaged and its brake is applied, the left-hand side being unaffected, so that the left-hand track alone is driven and the tractor steers to the right. In the last position the stop 90 bears against the roller 61 which thus prevents further rotation of the cam-wheel. The clutch 33 is actuated by a fork 46, Figs. 4 and 5, loosely mounted on the shaft 42 and connected through a spring 57 to an arm 38 fixed on the shaft 42. The spring 57 is compressed between a seat 49 formed on the fork 46 and a collar 58 secured on a bolt 53 pivoted to the arm 38. Disengagement of the clutch is effected by a direct contact between lugs 39 on the arm 38 and the seat 49 on the fork 46, whilst for engagement of the clutch the arm 38 presses on the fork through the spring 57 which can be compressed if the clutch teeth are not in position for immediate engagement. The brake band 64 is tightened by means of a shaft 70 which is connected to the shaft 42, so as to be operated thereby, by a link 77 and arms on the shafts.

Title: Improvements in or relating to porous metallic material
IPC: B01D39/12
Filed: 1958-07-08
Abstract: Porous material is manufactured from one or more sheets having metal portions overlying one another by subjecting the sheet or sheets to a cleaning operation, the subjecting the sheet or sheets to pressure so that the overlying portions firmly contact one another, sintering the overlying portions together while under pressure, and finally annealing the sintered material at a lower temperature while maintaining it flat.  A rolling process may precede and/or follow the sintering step.  When sheets of perforated or expanded metal are used, they may be so arranged that the holes are partially out of register with those of an adjacent sheet; when sheets of superimposed wire gauze are employed (preferably having a hollander weave) the warp and weft strands of one sheet are arranged to be at an angle to those of an adjacent sheet.  A reduction in pore size may be brought about by the rolling operation.  The sintering operation may be facilitated by etching or crimping the metal at the points of contact.
