Title: Fuel injection apparatus for internal combustion engines
IPC: F02M59/18
Filed: 1962-04-05
Abstract: 943,370. Fuel injection pumps. KLOCKNERHUMBOLDT-DEUTZ A.G. April 5, 1962 [April 7, 1961], No. 13140/62. Headings F1A and F1B. In a fuel injection pump having a piston 5 operated by a piston 13 which is moved on the suction stroke by pressure liquid supplied by a pump 1 through passage 6 to a space 12 and on the injection stroke by a spring 14 when the pressure in chamber 12 is released through pipe 36, a valve 4 controls the pressure supply and release pipes 6, 36, and the release pipe 36 contains a throttle which increases in area as each injection progresses. The pump 1 supplies pressurised fuel through pipe 7 to the pump inlet port 30 and the pump spill port 22 is connected to a drain pipe 17. The valve 4 actuated by an engine driven cam 33, opens passage 6 to the chamber 12 at the end of each injection so that piston 13 is forced down. When the valve 4 is lifted to initiate injection, passage 6 is closed and a tapering groove 35 connects chamber 12 to the release pipe 36, whereby spring 14 starts to raise piston 13 and pump piston 5. As valve 4 rises, the increasing depth of groove 35 increases the rate of escape of liquid from chamber 12 and the rate of injection increases. The valve 4 is guided by a pin 37 which may be adjustable. In a modification, Fig. 3, the groove 35 is of constant depth and the variable throttle in the release pipe 36 is formed by a tapering groove 49 in the wall of piston 13. The piston 13 may be adjusted angularly by an eccentric pin 53 to vary the effect of groove 49, and this adjustment may be effected by the pump control rod 58, Fig. 6, which conjointly adjusts the angular position of the pump piston 5 through an eccentric pin 60. A pump unit as shown in Fig. 6 may be combined with an injection nozzle for each engine cylinder, and the separate control rods 58 may be connected to separate hydraulic pistons which are controlled simultaneously by an hydraulic control system.
Patent GB-132778-A (GB)
IPC: D03C17/00
Abstract: 132,778. Damm, A. G. Sept. 14, 1918, [Convention date]. Cards, punching.-In jacquardcard punching-apparatus of the type wherein selenium cells are used as described in Specification 116,897, the camera is dispensed with, light from a lamp or lamps 4, Fig 1, passing through the apertures in an opaque screen and through the transparent part of the pattern or design 1 and acting directly on the selenium cells 2. The timing of the closing of the various circuits from a source of currents S and conductors 10, 6 is controlled by a commutator 9 comprising electrically-connected disks on a shaft 7 and corresponding brushes a, b, c, d, Figs. 1 and 2. The figure on the design may be in opaque colour or transparent paper, and the weave or binding in the figure and ground is provided for by using sheets 43, 44 of suitably-perforated non-conducting material passing over metal cylinders 29, 30. The lamp circuit is first closed and certain selenium cells 2 are illuminated whereby currents from the brush c and conductors 12 pass through corresponding electro-magnets 13, and corresponding armatures 42 are attracted, whereby relay circuits are closed and corresponding electromagnets 18 are energized. Armatures 41 connected by link rods 38 to levers 25 are thus attracted, so that certain of the levers 25 are moved against spring action into the positions shown in dotted lines. The levers 25 are electrically connected by brushes 24 and conductors 22 to electro-magnets 23, and certain of them make contact by means of their contact studs 27, 28 projecting through the perforations in the sheets 43, 44 with the metal cylinders 29, 30, which are electrically connected by brushes 31a and conductors 31, 19<a> to the commutator brush d, whereby certain electro-magnets 23 are energized. The corresponding armatures 32 are attracted and by means of elastic connexions certain punches 34 are moved into inclined positions against spring action, so that when the punching-head 40 descends, corresponding punches 48 are not operated. When an armature 32 is attracted, a corresponding contact member 21 is raised by means of a rod 35 into contact with a contactmember 20, and switch circuits are closed through the conductors 19, whereby the energized magnets 23 are maintained energized after the circuits from the brush c to the selenium cells have been broken, thus enabling these circuits to be closed for a short time only. All the holes in one longitudinal row of the jacquard card are punched at one time. The cylinders 29, 30 are rotated by special gearing. The opening in the screen is of such a form and size as to correspond with one small square of the pattern designing paper.
