Title: Fuel injection equipment including an hydraulic shuttle vlave
IPC: F02B75/02
Filed: 1973-01-23
Abstract: 1386191 Fuel injection pumps AMBAC INDUSTRIES Inc 23 Jan 1973 [24 Jan 1972] 3362/73 Heading F1A The delivery passage 54, Fig. 4, of a fuel injection pump 20 is alternately connected by a shuttle valve 58 to discharge passages 60, 62 leading to individual injection nozzles, the shuttle valve 58 being reciprocated in a bore 56 in synchronism with the pumping plunger 26 by fluid pressure acting alternately on its ends. Fluid is alternately supplied to and exhausted from each end of the bore 56 through a respective port 64a or 66a, Fig. 2, in a distributer porting plate 160, Fig. 3, and a passage connecting each port to the respective end of the bore 56. Each passage extends through a cover plate 84, the pump housing 76 and its side cover, a sleeve 98 supporting the pump barrel 28, a delivery valve holder 108 and a housing 52 containing the bore 56 for the shuttle 58. The ports 64a, 66a alternately register with arcuate high and low pressure/recesses 162, 164 in the lower gear 140 of a gear pump 138 which supplies fuel to the pump working chamber 106 during the suction stroke of the plunger 26. The recess 164 is in permanent communication with a drain and the recess 162 with the delivery passage 146 of the gear pump 138. To enable the gear pump 138 and distributer porting plate 160 to be removed for maintenance without disturbing the lobed cam 30 of the pump, the lower gear 140 has a stub shaft 148 splined to the cam shaft 32. A shaft 158 keyed to the upper gear 142 provides the input for a governor (not shown). Three constructional forms of shuttle valve 58 are described, two of which being operable to maintain pressure in whichever of the passages 60, 62 is not being supplied with fuel to be injected. In the embodiment shown, Fig. 7, this is achieved by a ball valve 192 disposed in an axial bore 184, 184b in the shuttle 58. Thus when actuating fuel is admitted to, say, the righthand end of the bore 56, the shuttle and the ball 92 move to their left positions shown. Accordingly, the pump delivery flows from passage 54, via an annular chamber 196, to the passage 62; at the same time pressure is prevented from collapsing in the passage 60 by the communication established by the ball valve 192 and ports 204 between the passage 60 and the righthand end of the bore 56. The quantity delivered by the plunger 26 is controlled in conventional manner by displacement of a rack 114 which controls the angular position of the plunger with respect to a spill port 126. By providing additional pumping plungers, each with an additional shuttle valve, further pairs of engine cylinders can be supplied with fuel.

Title: Improvements in and relating to abrasive elements for abrading tools
IPC: B24D9/04
Filed: 1933-02-04
Abstract: 404,150. Paper and like tubes. WARBURTON, R. E. L., 42, Rutland Gate, London. Feb. 4, 1933, No. 3467. [Class 99 (ii).] A tubular abrasive element or sleeve for use on the hub or other rotary part of an abrading- machine is formed by winding spirally a strip 1 of abrasive-coated material on a former or mandrel, the strip consisting of a backing sheet 2 having abrasive 3 secured by adhesive 4 over a portion of the width of the strip, and leaving an uncoated portion 8. When the strip is wound, the coated portion engages only over the uncoated portion of the next convolution, being secured by adhesive ; the strip may be wound to form a long sleeve, from which portions of the desired length may be cut, and the sheet 2 may be coated on a portion of both sides so that short lengths may be turned inside out for utilizing the original inner coating. In a modification, the strip is wound on a permanent mandrel in the form of a paper &c. tube, the uncoated edge of the strip being omitted and the edges of the convolutions abutting. In a further modification, Fig. 6, for use with fine abrasive, the strip has an abrasive coated portion 3a secured to a backing sheet 2, so that the coated portion overhangs the sheet 2 by a margin 8a of width equal to that of the uncoated portion 8. The element may be given a contoured surface by moulding, or the ends of a cylindrical length may be turned inwardly as described in Specification 404,151.
Patent GB-1186508-A (GB)
Title: Improvements in or relating to Photographic Cameras
IPC: G03B17/42
Filed: 1968-01-23
Abstract: 1,186,508. Camera mechanism. BALDAWERKE PHOTOGRAPHISCHE GER€TE UND KUNSTSTOFF R. GRUNTER K.G. Jan.23, 1968 [Jan.24, 1967], No.3536/68. Heading G2A. A camera in which a flash cube socket is rotated by the film transport mechanism has means for locking the said mechanism after rotation of the said flash cube has been completed. One embodiment is illustrated by Fig.3 and the remainder (not shown) of Figs. 1-6. Film transport is operated by a wheel 3, which is connected to the film supply spool when the camera casing is closed. Wheel 3 also drives a toothed disc (34) which, via a clutch connection, rotates the flash cube holder or socket (26). The locking mechanism comprises a slider 43, to which a lever 55 is pivoted at 54. An edge 56<SP>1</SP> of lever 55 can be brought into or out of engagement with the knurled edge 57 of wheel 3, this being the actual locking action. An end 47 of slider 43 extends into the plane of the film 44, and the other end 49 into the plane of the release plunger 66, 67. When a film is loaded into the camera, the leader has no perforations, so that the slider 43 is pushed to the right Fig.3 (not shown) by reason of its end 48 abutting against film 44. The locking edge 56<SP>1</SP> is therefore disengaged from wheel 3, and the other end 58 of the lever intercepts the release plunger path to prevent an exposure being made. The film can now be advanced by wheel 3, but the flash cube holder is prevented from rotating, the clutch merely slipping. When the first film perforation is reached end 47 of slider 43, urged by a spring 52, moves to the left, and engages in the perforation. Transport wheel 3 is engaged and locked, and shutter release 66 is free to move downwards. During this movement it engages a sloping end 49 of slider 43, drawing it to the right again and locking it against retraction. Further operation of wheel 3 now advances the film and also rotates the flash cube holder. When the next film perforation is reached, slider 43 once more retracts to lock the transport. If the camera contains no film, the clutch connection to the flash cube holder becomes ineffective, but the shutter release can still be operated for demonstration purposes. A second embodiment Figs.7-10 (not shown) is of rather more elaborate construction which provides a more precise and reliable operation.
