Title: Filters
IPC: C01B32/384
Filed: 1964-09-03
Abstract: A filter element, for use in a cigarette, cigar or pipe, comprises activated carbon granules bonded together by polyethylene, polypropylene or a mixture or copolymer thereof. The carbon may constitute 50-95% of the element by weight, and minor amounts of natural, synthetic or metal fibres, fibrous carbon or comminuted wood pulp may be included.  The carbon granules are much larger than the plastics particles, which are applied in powder form (50 microns diameter) or in an aqueous emulsion.  The granules and plastics may be extruded as a rod, with heating to soften the plastics bonding the granules together. Alternatively the carbon/plastics mixture is formed on a belt which is deformed to form it into a rod and heated, or the mixture is entrained in a gas stream and fed into a forming tube where it is bonded by injecting steam.  The rods formed in each case are subsequently wrapped, cut up and incorporated in cigarettes.ALSO:A filter element, for use in a cigarette, cigar or pipe, comprises activated carbon granules bonded together by polyethylene, polypropylene or a mixture or copolymer thereof.

Title: Improvements in or relating to pre-boarding machines
IPC: D06C5/00
Filed: 1953-12-30
Abstract: A pre-boarding machine for stockings comprises a steam chamber 10 having a vertically slidable door 11, two wheeled carriages 27 carrying formers 28, rails <PICT:0759525/IV(c)/1> <PICT:0759525/IV(c)/2> 26 on which one carriage at a time is movable into and out of the chamber 10, and pivot bearings 31 on the carriages which may engage with hooks 42 on brackets 51 slidable transversely to the machine on rollers 43 and rails 44.  The carriages may be pivoted by engagement of the bearings 31 with the hooks 42 to tilt out of engagement with the rails 26 into engagement with transverse rails 35, 36, or vice versa, whereby each carriage may be moved out of the chamber 10 on rails 26 and then transversely away from the chamber to permit the other carriage to be moved along the rails 35, 36 and then into the chamber.  In operation, when the carriage enters the chamber 10 it pushes back a plunger 46, compresses a spring 80, and releases a spindle 70 which springs up to close an electric switch 73 and lock behind a stop 45 to hold the carriage in position.  The switch 73 starts a motor 60, Fig. 2, which rotates a cam shaft 61 in an anti-clockwise direction. The door cams 67 raise the counterweighted door 11 through levers 17, 15, and immediately this is done a cam 64 operates a steam inlet valve 20, the steam pressing the door against a seal 12. After treatment the cam 64 releases the inlet valve 20 and a cam 65 opens an exhaust valve 21.  Following this the door cams open the door which drops into a well 13.  As the door reaches its open position a pin 77 on a cam 66 contacts a block 72 on the spindle 70 and depresses it until the block is clear of a roller 74 on the switch arm 75.  The spindle releases the block 45 and the carriage is then pushed manually from the chamber, the spring-loaded spindle 46 then re-engaging and holding down the spindle 70 (Fig. 7, not shown).  The pin 77 now clears the block 72, and the notch 78 in the periphery of cam 66 allows the roller 79 and switch arm 75 to spring forward and break the motor circuit.  When pushed from the chamber 10 the wheels 32 of the carriage run on the rails 26 until a retaining block 40 disengages from a holding rail 41 and the pivot bearings 31 engage hooks 42, the carriage may then be tilted out of engagement with the rails 26 so that the rollers 33, 34 may enter the rails 35, 36.  The rollers enter the rails through chamfered holes (Fig. 4, not shown), which lift the carriage very slightly to take its weight from the pivots 31. When the carriage is pivoted to an upright position it is engaged by pins 57 of a slidable strip 55 so that when the carriage is moved transversely the other carriage, which is also engaged by the pins 57, is dragged into entry position in front of the chamber.

Abstract: 1484946 Logic NAIGAI INDUSTRIES Inc 19 Aug 1974 [13 Sept 1973 29 Nov 1973] 36334/74 Heading G4H A logic circuit includes a plurality of unit circuits each comprising a NAND element having at least two input terminals and an inverter element connected to one input of the NAND element, the unit circuits being mounted on identical circuit boards and being interconnected in one of only two modes, wherein in one of the two modes the outputs of two unit circuits are connected to one another such that the two unit circuits are equivalent to two contact relays connected with their contacts in parallel and in the second mode the output from the NAND element of one unit circuit is connected to the inverter at the input of the NAND element of the second unit circuit such that the two unit circuits are equivalent to two contact relays connected with their contacts in series. The other input of each NAND corresponds to the coil of the relay and may include an inverter in series with it. A multi-contact relay is simulated by having the second-mentioned inputs to the NANDs connected in common, this common connection between supplied by a parallel circuit of two branches with one inverter in one branch and two inverters in series in the other branch, one branch or the other being used according as normally-open or normally-closed contacts are to be simulated. Terminals may be provided permitting connections to be inserted in use to give normally-closed or normally-open operation for all the NANDs or some normallyclosed and some normally-open, as desired. A capacitor may be inserted for delayed operation. The circuitry is implemented in integrated form on a stack of circuit boards which are interconnected. Each board simulates two (or one) multi-contact relays and includes a D.C. stabilized power supply circuit. Each board has indicators (LEDs) for the power supply and relay-analogues. An external mechanical switch may control the logic circuit via an interface circuit to eliminate contact chatter, the logic circuit controlling a relay, lamp, TRIAC or A.C. circuit, via an amplifier/driver.

Title: Railway vehicle bogie
IPC: B61F5/44
Filed: 1959-10-27
Abstract: 936,802. Railway vehicle undercarriages. GENERAL STEEL INDUSTRIES Inc. Oct. 27, 1959 [Nov. 20, 1958; March 5, 1959], No. 36456/59. Class 103(6). A railway vehicle bogie Figs. 1, 2 -and 3, comprises three parallel and vertically movable axles 2, 3, 4 each driven by a motor M, and a radial truck having a single idler axle 6 the rigid bogie frame being supported by the driven axles and on the truck which has bolster 42, Fig. 3, movable transversely of the truck frame 37 against the action of a resilient centering device including two pairs of pivoted sector members 43. An equalizing system provided at each side of the bogie frame comprises a pair of yokes 9 bearing at 10 on the axle box 7 of the middle driven axle, the ends of the yoke pair being pivotally connected to pairs of pendant links 13 in turn pivotally connected to the ends of pairs of longitudinally directed rigid beams 16 having goose-necks engaging at 18 with the axle boxes of the end driven axles. The bogie frame side members 22 are mounted on coil springs 20 carried by the beam pairs 16. The yokes of each pair and the beams of each pair are dispersed on opposite sides of the side member 22 as shown in Fig. 1. The truck frame 37 supported from the axle boxes of the axle 6 by springs 35, is connected to the bogie frame by diverging links 48 having at each end elongated rubber bush-type vertical pivots 50, 52. Referring more particularly to Figs 3, 9 and 11 the truck frame transoms 40,41 each pivotally carry a pair of segmented members 43 having circular edges 83 engaging sloping bearing surfaces 100 carried by the underside of the bolster 44 having a pivotal connection 46, 46a with the bogie frame. As shown in Figs. 9 and 11 the flanges of opposed members 43 are joined together and arched over the axle 6 at 84 and depending teeth 101 on the bolster engage in apertures 102 in the arches. Each member 43 has press-fitted therein, a resilient bush comprised of inner and outer metal sleeves 87, 85 and a rubber sleeve 86. The sleeve 87 is prevented from rotation relative to the trunk frame by having serrated end surfaces 96 frictionally engaged by the head 77, of a pin 76 passing through the resilient bush, and the inner face of the transom. The pin 76 is secured in position by a nut 95. As the bolster moves laterally of the truck frame when the truck enters a curve, the movement is resisted by the rubber sleeves in shear. In order to achieve a substantially constant resistance throughout the range of bolster movement the slope of the bearings 100 varies as shown in Fig. 12. The arrangement of the links 48 ensures that the axle 6 will be radially directed as it moves over a curved truck. If provision is made for lateral movement of the axle 3 then the depending links 13 can also pivot about axes extending longitudinally of the logic frame but lateral movement of the beams 16 is prevented by providing them with end extensions engaging bearing surfaces of the pedestal legs for the axle box, all as described with reference to Figs. 4 to 8 (not shown).
