Abstract: 1,165,435. Rotary positive-displacement pumps. P. VULLIEZ. Oct. 5, 1967 [Oct. 6, 1966; Sept.29, 1967], No. 45466/67. Heading F1F. A rotary positive-displacement pump of the gyratory-piston type comprises a fixed body 10 defining an annular cavity 15 that contains a partannular piston, or movable member, 16 and an arcuate partition 11a between a suction passage 27 and a pair of delivery orifices furnished with non-return valves 31, 32, which orifices are controlled by the piston as it gyrates while being driven by mechanism including a rotatable shaft 26 and three crank-shafts 20 whose crank-pins 18 are lodged in bearings within the piston, eccentrics on the shaft 26 and the crank-shafts being synchronously coupled to one another by a member 24. A mass or weight 25 on the shaft 26 effects dynamic balancing. Bellows 23 enclose each of the crankshafts and parts associated therewith, and a semicylindrical member 19 pivotally connects one end of the piston to the body 10. The piston is rendered in sliding contact with the body 10 such that working fluid is displaced on its radially innermost and outermost sides when it gyrates. The member 24 and the shaft 26 may be dispensed with, the piston then being driven by one of the crank-shafts. In each of two other embodiments, Fig. 3 and Figs. 4 and 5 (not shown), the piston or movable member has the configuration of a spiral, the laterial walls of the cavity containing the piston being of generally similar shape. In another embodiment, Fig. 6, two pistons, or movable members 16a, 16b of spiral shape are provided, these members being driven in antiphase relationship with each other by respective crank-pins (18a, 18b, Fig. 7, not shown), on three crank-shafts 20, one of which is connected to external driving means. A common suction passage 27 communicates with two spaces between the pistons, a single discharge non-return 31 being provided adjacent the centres of the pistons. One of the pistons may be rendered fixed relative to the body 10. A further embodiment, Figs. 8 and 9 (not shown), is generally similar to that according to (Figs. 4 and 5,) the mechanism for driving the piston being basically similar to that shown in Figs. 1 and 2. It is indicated that the pump may be used as a vacuum-pump.

Abstract: 1428088 Injection moulding machines BRITISH SHOE CO Ltd 29 Oct 1974 [29 Oct 1973] 46648/74 Heading B5A Moulding apparatus comprising a mould part 1 movable by a mould cylinder 5 and piston 6 relative to a fixed mould part 2, includes a control system comprising a control piston 36 in a cylinder 16 having one end connected to the mould cylinder 5 and its other end connected to a fluid pressure source 15, whereby the control piston 36 moves in unison with the mould piston 6, a valve 28 for preventing return of fluid to the source 15 when the mould part 1 and piston 6 are moving in one direction, and an adjustable stop means 38, 40 for limiting movement of the control piston 36 and consequently of the mould piston 6 and mould part 1. The apparatus can be used for moulding microcellular shoe soles by two methods (i) by injecting a predetermined quantity of sole material and controlling the mould opening movement during expansion, and (ii) "squash moulding" by injecting into a partly opened mould which is then fully closed. In the first method, if the pressure within the mould cavity is insufficient to raise the mould part 1, air under pressure is fed into chamber 7 of cylinder 5 to assist mould opening. When mould part 1 begins to rise a microswtich 32 is closed to actuate a solenoid 30 and de-energize a solenoid 45, thereby closing valve 28 and opening a valve 42 to vent the top of the reservoir 15 to atmosphere. Fluid from chamber 8 of cylinder 5 flows into chamber 23 of cylinder 16 causing piston 36 to rise until stopped by nut 40 engaging a fixed plate 34. Pistons 36, 6 and mould part 1 are simultaneously stopped. For the second method the microswitch 32 is closed when the mould is closed. A pressure intensifier (50), Fig. 2 (not shown), may be inserted in the line 18 between the reservoir 15 and the cylinders 5 and 16.

Title: Data display apparatus
IPC: G09G1/10
Filed: 1966-10-24
Abstract: 1,139,057. Cathode - ray tube displays. INTERNATIONAL BUSINESS MACHINES CORP. 24 Oct., 1966 [9 Nov., 1965], No. 47519/66. Heading H4T. The beam of a cathode-ray display tube 12 (Fig. 1) is deflected along a path approximating to a straight line (see Fig. 4) by the application, successively to the X and Y deflection means, of one or more incremental deflections the particular axis receiving more than one incremental deflection being determined by the slope of the particular trace. The slope in the form of a binary number and always expressed as a number less than unity is fed to a register 36 and to an adder 56, a signal indicative of the form of the slope so expressed, i.e. #Y/#X or #X/#Y being fed to a trigger 38 and other signals indicative of the signs of #X and #Y being fed to triggers 32 and 34 respectively. Additionally, the number of incremental deflections which each component #X and #Y deflection requires is set up in counters 28 and 30 respectively. In operation, the first clock pulse fed via gates 52, 51 operates via either gate 43 or 45 as selected by the slope indicative input from trigger 38 to step counters 28 or 30 down by one increment and via that one of gates 47 ... 50 selected by the sign triggers 32, 34 to step counter 22 or 24 up or down by one count and provide via the appropriate D/A connector 18 or 20 an incremental deflection along either the X or Y axis of the tube. The clock pulse additionally operates ADD gate 54 and adds the slope in register 36 to the slope, in this case to itself, already in adder 56. If the result of this addition exceeds unity the " carry " (from the most significant phase 58) is utilized to produce, via a single shot multivibrator 62, a pulse of one clock period duration which inhibits gate 51 and opens gate 42 so that the second clock pulse is effective via either gate 44 or 46 determined by trigger 38, to step down counter 28 or 30 and via the appropriate gate 47 . . 50 to produce a further incremental deflection. The gates 43 ... 46 and trigger 38 are so connected that if the first clock pulse results in an incremental deflection in the Y direction and the result of the addition of the slope to adder 56 produces a " carry " the second clock pulse results in an incremental deflection in the X direction. In this case no operation of ADD gate 54 is effected. If, however, the addition results in a number less than unity the second clock pulse results in a further deflection in the Y direction and a further addition is effected via ADD gate 54. This cycle of operation, as depicted in Fig. 3, where the slope is considered for convenience as 0À7, continues until both of the counters 28 and 30 have been reduced to zero when the output of AND gate 68 inhibits further clock pulses via gate 52.
