Abstract: 506,561. Reciprocating pumps. AMERICAN ENGINEERING CO. March 23, 1938, No. 8941. Comention date, March 24, 1937. [Class 102 (i)] [Also in Group XXIX] Liquid pressure motors 154 operated by a pump 140 are controlled by a main . valve 163 controlled bv a second valve 175 operated by the pump pressure opposed by an auxiliary source of pressure supplied, e.g. by a pump 198. The motor supply and discharge pipes 151, 152 are connected to the upper ends of valve elements 190, 184 respectively; the opposite ends of the valves being subjected to the auxiliary pressure. At the end of the motor stroke, pump pressure builds up in the supply pipe 151 and moves valve 190 against the opposing pressure to connect the upper end of a cylinder 170 to pump pressure, thereby reversing the main valve 163 and the motors. In an alternative arrangement, Fig. 1, the main valve controls supply and discharge of nuid to a motor 19 for reversing the main pump 1. The main and pilot valves are in this case arranged at right-angles i-ii the same casing tmdttttttched to the motor 19. The main valve is operated by pump pressure on one or other of its ends. The stroke of the pump 1 is adjusted by rotating a handwheel 132 to vary the position of collars 130, 131 on either side of a bridge 122 carried by the reversing mechanism of the pump. U.S.A. Specifications 1,077,979 and 1,656,034 are referred to.

Abstract: 876,820. Automatic discharge from endless conveyers. SCHUHUND SATTLERMASCHINENBAU LEIPZIG VEB. March 17, 1959, No. 9281/59. Class 78 (1). Carriers 5 are supported at 9 and are propelled by endless chain 11 so that they transport containers 2 around a closed circuit of discharge stations. Each container is hooked at 15 on to its carrier 5 and carries two adjustable contacts 3 and a fixed contact 4 (Fig. 6), which contacts are manually given a setting to correspond with and to engage respective levers 17 at the predetermined discharge station to cause the container to be unhooked at 15 from its carrier and so discharged. Discharge operation.-The discharge of a container is effected by flap 24 pivoted at 27. It is influenced upwards by the weight of link 33 acting via lever 30 upon the flap at 28, and this clockwise rotation about 27 is resisted by the three levers 17, which levers are pivotable about respective vertical pins 19 and bear against projections 25 disposed on flap 24. When all three contacts 3 and 4 simultaneously and rotatably flick all three levers 17 off their respective projections 25, flap 24 is free to be pressed upwards by lever 30 at 28 so that the edge 37 of the flap engages and lifts bar 15 of the container to allow the container to slide down the discharge station 6. At the latter station it rests on trigger 35 so as to cause the linkage 32, 33, 30 to withdraw support from flap 24. The latter therefore falls thus moving out of engagement with levers 17. Subsequent containers then pass and flick the levers 17 without effect and no discharge of a second container can be made at the same station till trigger 35 is allowed to rise by the removal of the first container.

Abstract: 1421587 Small arms BENELLI SpA DIVISIONE ARMI 27 Feb 1973 [29 Feb 1972] 9501/73 Heading F3C An automatic pistol has a fixed barrel, Fig. 1, a cartridge receiver breech 10 having grooves 8 therein, Fig. 4, a recoiling bolt carrier 2, Fig. 1, a bolt 3 having transverse ribs 7, Fig. 6, which co-operate with the grooves 8 of the breech 10, and has a link 4, Fig. 1, having one end received in a cavity 19 formed in the bolt 3 and the other end engaged by an inner surface of the carrier 2 and by a stop element 5 which is coupled to the latter. The bolt 3 is urged towards the breech 10 by a spring 6 which is mounted on a rod 17 located in a housing 15, the latter being attached to the carrier 2. The spring 6 has one end thereof engaging a surface 18 of the breech 10 and the other end engaging a flange of the housing 15. Thus the force of the spring 6 is conveyed to the bolt 3 via the carrier 2 and its stop element 5 and via the link 4. The bolt 3 engages a cartridge case 20 which is in the barrel 1 and has a hole 21, Fig. 7, formed therein to receive a firing pin 13, Fig. 1. On firing the pistol the pin 13 is struck by a hammer 14 to urge it against the cartridge detonator, whereupon explosion of the charge is effected. The inertia of the bolt carrier 2 tends to maintain its position relative to the other parts of the pistol and is assisted by the forces of the spring 6 and the explosive gases, both of which act through the link 4. The bolt is then recoiled by the gases, the ribs 7 are disengaged from the grooves 8, this operation being facilitated by the provision of inclined surfaces 12, 11 at the ribs and grooves respectively, and the cartridge case 20 is ejected. The bolt 3 and its carrier 2 are returned by the spring 6 and a new cartridge is positioned in the barrel 1.

IPC: B41N3/00
Filed: 1929-03-25
Abstract: 330,674. Trist, A. R. March 25, 1929. Printing-surfaces; etching.-An intaglio printing-plate is formed with a dot image produced by the use of a photogravure screen and the recesses are surfaced to enable them to retain ink applied by rollers associated with means such as a scraper for removing ink from the non-printing areas. Preferably the plate comprises an iron base coated electrolytically with nickel and on which a layer of chromium is electrolytically applied. Local resists of colloidal material are applied to the chromium by photographic means, these resists being supplemented if necessary by an electrolytically-deposited layer of nickel; in this case, the chromium is first activated by generating hydrogen thereon. The nickel nesists are formed by etching with a fluid which tends to harden the colloid material. The exposed chromium is removed with a mixture of hydrochloric acid and glycerine, and the nickel thus exposed is removed electrolytically. The iron thus exposed is oxidized or otherwise roughened to enable it to retain ink.

Abstract: 1,173,232. Respiratory apparatus. AIR REDUCTION CO. Inc. 1 March, 1967 [11 March, 1966], No. 9716/67. Heading A5T. {Also in Divisions B7 and F2] A mixture of gases for breathing is supplied to a diver in a manner such that the proportions of the gases in the mixture are varied automatically according to the depth of the diver. As shown, the diving apparatus supplies helium 26 and oxygen 36 to the diver 14 via valves and pressure regulators 26c, 36c, a flow control means 22, a mixer 46, a surge tank 48, regulating devices 54, 58, and a hose 12. The flow control means 22 (see also Figure 2, not shown) includes solenoid controlled on-off valves (32A, 42A, 72A) supplying the gases in response to a pressure actuated switch 60 in the tank 48, and a solenoid controlled valve (32C) dependant through a hose 18 on the depth of the diver and arranged to automatically increase the proportion of helium in the breathing mixture as the diver descends. The regulating device 54 (see also Figure 4, not shown) automatically maintains the pressure of the gas mixture flowing to the diver above that of the surrounding water, or it may be bypassed by the manual regulator 58. The apparatus may be controlled manually using valves (72B, 32B, 42B) which by-pass the valves automatically controlling the gas proportions. An alternative apparatus (Figure 2, not shown) includes a source (66) of nitrogen which may also be added to the breathing mixture automatically or manually as the diver descends. This apparatus includes a second surge tank (248) which may be filled with gas of a slightly different composition to that of the first surge tank 48 so that the diver may be supplied, in manual operation, in turn from both tanks as he ascends or descends. The apparatus also includes a second group of cylinders 78 containing gas of a predetermined mixture for emergency use. The valves (32C, 72C) controlling the flow of gas in accordance with the divers depth utilize contoured cams and cam followers (Figure 5, 6, not shown).

Filed: 1943-06-17
Abstract: 565,906. Extracting cores. FLOWERS, P. E. June 17, 1943, No. 9738. Convention date, April 9, 1942. [Class 83 (i)] [Also in Group XXIX] A device for selectively moving a core first in one direction and then in the other, includes an intensifier adapted to exert intensified pressure on the core to start its movement in the second direction. The core is mounted on a rod 26 connected to a piston 13 in a fixed cylinder 9 and is ex. tracted by admitting pressure fluid at 10 while ex. hausting at 11. The pressure fluid forces down a piston 20, against the action of a spring 29, thereby forcing fluid at a greater pressure from the chamber 23 through a passage 27 into the cylinder 9 below the piston 13 which is thereby moved up to start the core. Fluid in the space 20b passes via a passage 33 and one - way valve 34 to exhaust. This movement of the piston 20 uncovers a port 32 and admits fluid pressure from 10 direct to the lower end of the cylinder, thus completing the extraction. When the pressure at 10 is released, the spring 29 returns the piston 20 to its original position, the spaces 20b and 23 being refilled via passages 30 and 27 from the lower end of the cylinder 9. When pressure is admitted at 11 and exhausted at 10, the core is inserted in the mould by downward movement of the piston 13, the fluid in the lower end of the cylinder 9 escaping via passages 31 and 33.
