Abstract: 1,011,601. Reciprocating pumps. JOSEPH LUCAS (INDUSTRIES) Ltd. Nov. 27, 1963 [Nov. 27, 1962], No. 44849/62. Heading F1A. In a rotating cylinder swash plate pump with arcuate inlet and outlet ports 19, 20 in a stationary block 18, pressure pulsations in the outlet port 20 are reduced by at least one piston 24 actuated by a cam 26 so as to increase the volume of the space 20 at instants corresponding to peak pressures therein. In the nine cylinder pump shown, the outlet port 20 is provided with three pulse reducing pistons 24 actuated by a cam 26 on the rotating pump shaft with three flats 27 thereon. The flats 27 actuate the pistons 24 in turn so that as each pump bore 15 registers with the port 20, a piston is driven radially outwardly to counteract the slight drop in pressure and mid-way between the instants when successive pump bores 15 start to register with port 20, a piston 24 is caused by a flat 27 to move radially inwards to minimise the pressure peak which normally occurs at this instant.

Filed: 1973-09-28
Abstract: 1403820 Buckles INTERNATIONAL ENG SERVICE Inc 28 Sept 1973 45535/73 Heading E2A  A seat belt buckle assembly comprises a tongue 16 for attachment to a belt part 14, the tongue having an opening 20, a buckle member 10 attachable to a second belt part 12, a latch 48 pivoting in the buckle member to engage in the tongue opening, a release member 70 pivotally mounted in the buckle member to release the latch and is releasably engageable with the latch to prevent its removal from the tongue member and a spring member 60 which urges the latch towards removal from the tongue opening in response to the release motion of the release member. The buckle member comprises a housing 86 for a channel shaped member 28 with side openings 40, 42 in which lateral fingers 50, 52 on the latch 48 pivot.

Title: Improvements relating to filling apparatus
IPC: B67C3/06
Filed: 1961-12-20
Abstract: 966,246. Bottling. SEITZ-WERKE G.m.b.H. Dec. 20, 1961 [Dec. 24, 1960], No. 45628/61. Heading B8T. A rotary multi-head counter-pressure type filler includes an annular liquid chamber 10, Fig. 1, an annular chamber 12 from which compressed gas, e.g. air, is supplied to pressurize a vessel, e.g. a bottle to be liquid filled, and a chamber 38, Fig. 3, for the reception of gas from the vessel when liquid is being supplied to it. Each filling head 13 has a filling tube 16 supplied via a passage 26 and a valve 28; the latter is urged by a spring 29 towards its open position but is held closed by an eccentric 22 on a valve shaft 21. The latter is turned about its axis by a star-wheel 20 having arms which strike corresponding stops as the filler rotates; thus a valve face 19 attached to the shaft is turned relative a fixed valve disc 18, whereby to control the flow of compressed gas to and from the bottle. The valve disc and face have passages therein which, depending on the position of the star-wheel, interengage to control the gas flow therethrough. As shown in Figs. 1 and 2, a passage 30 feeds compressed gas from the chamber 12 to a passage in the valve, and a passage 31 leads from the valve to the upper end of the filler tube 16 to act as an equalizing passage. A further passage 32 extends from the valve to supply the bottle. A return air passage 33 leads from the filling tube to a passage 34 containing a float 35 for closing the return air passage when the liquid rises therein. The return air passage leads via the valve to a passage 36 and the chamber 38. Initially, the valve 18, 19 enables compressed gas to pass through the passage 32 into the bottle; the star-wheel is then turned so that gas may flow directly from the bottle to the chamber 38, by-passing the float 35. Further movement of the star-wheel causes the liquid valve 28 to be opened, thereby filling the bottle, and the displaced gas passes to the chamber 38. When the liquid level reaches the opening 33a, Fig. 2, it flows up the passages 33, 34. The float closes the return air path. The starwheel is again turned to bring the passages 31, 32 and 34 into communication, whereby liquid in the tube 16 and in the return air passage is fed into the bottle. Continued wheel movement connects the passages 31, 32 and 34 to a pressure release port 46 so relieving pressure through a throttle 40 and passage 39. The bottle is then removed from the filler, after which the star-wheel moves to a position where compressed gas is blown through the air return passages and filling tube to remove any liquid therein. In the modification of Fig. 4 the liquid filling tube is replaced by a part 52 having an air return tube 49 about which the liquid flows to the bottle which is applied to a centring device 54 supported by rods.

Title: Method and apparatus for radiant energy measurement of impedance  transitions in media for identification and other purposes
IPC: G01V1/37
Filed: 1973-10-01
Abstract: 1447873 Wave-energy impedance transition measurement BOLT BERANEK & NEWMAN Inc 1 Oct 1973 [16 Oct 1972] 45735/73 Heading H4D Impedance transistions in a medium are measured by transmitting wave energy into it in a predetermined direction, receiving the energy returned from the medium, deconvolving the transmitted and received energy to produce a reflection impulse-response function, and integrating this function to provide an impedance-transition measurement which may be compared with properties of known media to identify the nature of the medium. The waveenergy may be acoustic, visible or invisible light, radio, microwave or heat. The invention is applicable to seismic exploration, non- destructive testing of laminates, and medical diagnosis. In the Fig. 1 embodiment for investigating the nature and gas content of marine sediments 5, an acoustic pulse source 1 and receivers 2, 3 are supported by a frame 4. Clock pulse generator 6 and the receiver 2 position are adjusted such that the wave travel times from source 1 to a receiver and between receivers are integral multiples of the clock pulse interval, to simplify received signal processing. Closure of switch 8 triggers source 1 and the sweep of a CRO 10 on which the receiver signals are monitored. The receiver signals are sampled, preferably at the Nyquist minimum rate, at intervals defined by the clock pulses and are recorded at 20, 21. From the samples the downgoing (transmitted) and returning waveforms are computed. The two computed waveforms are then convolved, the convolution result is integrated with respect to time, and the resulting acoustic impedance measure is displayed as a function of the wave travel time in the sediments 5. Source 1 may be directional and actuated repeatedly so that successive waveform signals can be averaged to enhance the signal-to-noise ratio. Mechanical or electronic scanning of transducer arrays is also envisaged. The apparatus may be towed by a ship. A single receiver movable vertically may be used instead of the two receivers shown. Receiver signal samples are obtainable by analysis of a photograph of the CRO display.

Abstract: 1,015,144. Moulding reinforced plastics bars. BARMER MASCHINENFABRIK A.G. Dec. 13, 1962, No. 47142/62. Heading B5A. In making bars, e.g. of T, H, U or L section, strands or woven bands of glass-fibre 1 (Fig. 1) are impregnated with a curable polyester resin and then continuously covered with a layer of thermoplastic (nylon-6 or high-density polyethylene) in an extruder 10, the thermoplastic having a melting point above the resin curing temperature. The curing of the resin may thereby be initiated, in which case shaping of the bar (Fig. 3) follows at once. Alternatively, quick cooling of the bar emerging from the extruder may prevent curing, and the semifinished bar is wound on to a reel 13 for storage and is later reheated, shaped and cured. Strands 1 are resin-impregnated in vat 2 and sprayed with short fibres in chamber 5, to reinforce the final bar transversely. The strands are brought together, sprayed with more short fibres in chamber 8, coated in extruder 10 and the thermoplastic coating cooled in bath 11. The bar is shaped and cured by alternate heating chambers 14, 15, 16 and rollers 17, 18. The rollers may be changed to form a bar of varying cross-section. The formed bar may be still incompletely cured, being later longitudinally curved or wound into a helical spring and then cured. Several curved bars may be used to form a leaf spring.
