Abstract: 950,008. Moulding-machines. OSBORN MANUFACTURING CO. Dec. 8, 1961 [Aug. 24, 1961], No. 44103/61. Heading B3F. A moulding machine comprises a frame 2, a squeeze ram assembly fixedly mounted on the upper part of the frame, a horizontally movable squeeze head 82, and means for shutting the squeeze head to a position beneath the ram assembly in which position it can move vertically under the action of the squeeze ram. The squeeze head 82 is shuttled horizontally by a sand carriage 36 to which it is loosely coupled by a pin 92. The sand carriage assembly is moved by cylinders 60, 61 between a position in which it receives sand from a hopper 27 and a position over a flask in position on the pattern P, and comprises louvres 52 controlled by cylinders 48, 49 to discharge sand into the flask. Movement of the carriage to the sand discharging position beneath the squeeze ram assembly places the squeeze head in the position shown dotted in Fig. 1, and drags a flask F by means of a latch 67 into position on to rollers 143, 144 carried by a frame 130 supported by the pattern table and vertically movable by cylinders 137, 138 between an upper position in line with the conveyer sections 72, 165 to receive a flask, and the lower position shown in Fig. 1 in which the flask is placed on the pattern plate. The pattern table is mounted on a jolt piston 111. After discharge of sand into the flask, the carriage 36 is retracted to the position beneath the hopper 27 for recharging, bringing the squeeze head 82 on to the rollers 100 of a frame 20 forming part of the squeeze ram assembly. The squeeze head is then moved down to compact the sand, the initial movement causing spring- loaded latches 171, 172, Fig. 3, to hold the squeeze head in the frame 20. The rollers 143, 144 of the vertically movable frame 130 are supported by short-stroke pistons 139, 140 which in their lowermost position bring the rollers below the tops of draw pins 162, Fig. 5, which then support the mould during its stripping from the pattern by elevation of the frame 130 by the cylinders 137, 138. The pistons 139, 140 are then elevated to lift the mould from the draw pins and align on the rollers 143, 144 with the exit conveyer 165.

Box ends E are stored in hoppers 44 and the lowermost is removed by a stripper block 124 on a chain 48 and turned by guides through approximately 90 degrees and subsequently engaged by pusher element 166 on the chain 48 and fed to an elevator assembly Fig. 9A. An exit gate gate on the hoppers is spring-loaded to avoid jamming. At the elevator rises, members 172 lift the ends E into engagement with flat M. Each flat has previously been placed manually on a table 52 where cam operated fingers 58 push it between nip rolls 62, 66 so that it is fed across the path of the rising end pieces E. The elevator is raised by cam (198, Fig. 2B) and associated levers (202, 212, Fig. 2B) the cam being shaped to give the initial rising movement and three subsequent dwells for the stapling The flats are supported on ramp plates 284, Fig. 9A, and folding members 298, Fig. 10, fold down the flat against the ends E. Springs 300 urge the members 298 inwardly and rollers 306 engaging cams 304 move them outwardly as the elevator descends. Previously assembled boxes C, Fig. 9A, are raised by lower boxes subsequently formed and are held by pawls 450, the uppermost box being removed to an exit plate by rollers 460 on push arms 70 driven intermittently by a chain 364. The drive means comprises a main motor 50 and a motor 64 driving the flat feeding means. If either of the end pieces of the flat are absent sensing switches will stop the machine. Similarly any jam-up of the conveyer chain 48 will cause a chain-overload switch to be operated to stop the machine. A stapling mechanism is provided at each box carrier and draws wire W from a reel and feeds it by rolls 408, 418, Fig. 13, to a tube 442 and then to a former 346 which bends the wire to U-shape Fig. 17 adjacent the box ends E. A driver 348 inserts the staple and in so doing rocks the former 346 so that its nose is withdrawn from the staple. The staple former and driver are cam operated and the former is set 60 degrees in advance of the driver. The box walls are inclined slightly towards their tops consequently each stapling mechanism is moved slightly inwardly between each of the three staple insertions, this is accomplished by cam plates (338, Fig. 11A) the boxes being assembled with their bases uppermost.

Title: Anti-wheel-slip device for motor vehicles
IPC: B60T8/175
Filed: 1971-09-30
Abstract: 1361425 Preventing wheel-spin ALFRED TEVES GmbH 30 Sept 1971 [7 Oct 1970] 45535/71 Heading F2F To prevent wheel-spin, a vehicle anti-skid system is used, during acceleration of the vehicle, to automatically brake any wheel which accelerates too quickly. The principle may be applied to systems which release pressure fluid from the brake line or to systems which operate by increasing its volume. In the first kind, Fig. 1, pressure from master cylinder 1 to brake 2 is normally released by valve 6 under control of wheel speed sensor 8 through electronic controls 9, 10, 11, 12 and amplifier 13. An input valve 3 is also controlled by amplifier 14. For the purpose of this invention, the anti-wheel-spin function is switched in by control 15 which connects a trigger 16 which opens a valve 18 through amplifier 17 to draw pressure from store 20 to brake the wheel at 2. In the other system, shown in Fig. 3, pressure from master cylinder 26 to brake 27 passes through a displacement cylinder 28 connected to pressure store 35 by valve 34 and to reservoir 38 by valve 37. A sensor 39 controls these valves through circuits 40, 41, 42, 43, 44 and 45. Excessive deceleration operates these valves to cut off the reservoir and connect the accumulator to chamber 32 of the displacement cylinder 28. This closes pressure-feed valve 28 and so increases the volume as to reduce the braking pressure. In order to prevent wheel-slip, an additional trigger 48 opens a switch 49 in circuit 50 energized by manual closure of switch 51 and also acting on the valves 34 and 37 to feed the brake from the cylinder 28 under the action of spring 47.

Abstract: 1401466 Filter and addition SEITZ-WERKE GmbH 10 Oct 1972 [11 Oct 1971] 46601/72 Heading B1D A system is provided for continuously adding varying quantities of two separate filter aids to a stream of beer flow from a storage tank 13 to a filter 10, one filter aid being for the removal of permanently present yeast sediment whilst the other is for the removal of albumen sediment which only deposits on cooling of the beer. The two filter aids are added by metering devices 23, 24 controlled by electric motors 29, 30 and provided with flowmeters 27, 28 to measure the amount of filter aid flowing per unit time in lines 25 and 26 and thus being added. A pair of turbidimeters 18 and 19 mounted in series in a bromie conduit 17 off the main fluid flow line 11 measure the amount of sediment. The first turbidimenter 18 measures the total amount of sediment (yeast plus albumen). The second turbidmeter has a heating zone 20 positioned upstream to re-dissolve the albumen. This turbidimeter thus measures only the amount of yeast sediment. A flow-meter 15 measures the total amount of beer flowing. The valve from the turbidimeter 19 is fed directly a, b, c, to a multiplication stage 37 where it is combined with the flowmeter value to give the amount of yeast sediment per unit time. This value is then compared in an actual-value comparison stage 39 with the amount of corresponding filter and being added by metering device 23 and as measured by flow meter 27 and the motor 29 and, hence, amount of filter aid being added is varied accordingly. The values from turbidimeter 19 is also led together with that from turbidimeter 18 to a subtraction stage 35 the product of which is a value corresponding to the amount of albumen sediment. This value is then treated similarly in a second multiplication stage 36 and actual-value comparison stage 38 to adjust the amount of filter aid being added by metering device 24. The filter aids added may be two different kieselguhrs.
