IPC: B65G59/00
Filed: 1968-09-17
Abstract: 1,246,137. Feeding sheets. USM CORP. 17 Sept., 1968 [18 Sept., 1967], No. 44124/68. Heading B8R. Apparatus for feeding plies of fabric material from a stack to a receiving surface comprises a suction member carried on a support movable between pick-up and depositing positions and a stripper which is relatively movable with respect to the suction member for disengaging a ply therefrom at the receiving surface, both the suction member and the stripper being movable towards or away from the receiving surface at the depositing position. General arrangement, Fig. 1. An elevator 12 supports a pallet 32 on which stacks S 1 , S 2  are located, and is mounted on track 22 for vertical movement under the action of endless chain 26 and sprockets 28, 30, the sprocket 30 being positively driven. A carrier arm 14 provides support for a work head 16 comprising a carriage 46 which is reciprocable along an arm 44 under the action of double-acting fluid-pressure cylinder 42. The carriage 46 supports a plurality of separating devices 60, each connected to tubular members 58. In use, plies of fabric can be separated alternately from stacks S 1 , S 2 , and delivered to a single receiving station by the devices 68, or the plies can be separated in turn from a single stack and fed to two alternative locations. Fixed limit switches LS2, LS3 and adjustable limit switches LS4, LS5, control these functions, the switches being actuated by a flange 80 on the carriage 48, and switches LS3, LS4 and LS5 being equipped with shock absorbers 70, 76, 78. Separating means (Fig. 6).-Each separating device 60 comprises an outer cylinder 116, a hollow tubular member 128 and, interposed therebetween, a stripping element 132; the lower end of tubular member 128 supports ply-gripping means in the form of card cloth 146. The tubular member 128 and stripping element 132 are biased by springs 142, 144, movement being limited by pin 140 which co-operates with slotted openings 136, 138 in the movable elements. Suction is applied to tubular member 128 through horizontal tubular member 58, and air lines 112, 114 supply pressure to tubular member 128 and stripping element 132 for controlled movement against the bias of springs 142, 144. In operation, (a) tubular member 128 is extended and suction applied to grip a ply with the card cloth, Fig. 6 ; (b) the member 128 is retracted with the ply remaining thereon, (Fig. 7, not shown); (c) the carriage 46 travels to depositing position where the member 128 is again lowered (Fig. 8, not shown); (d) stripper member 132 is lowered to contact the ply (Fig. 9, not shown); (e) suction is cut off, and member 128 is retracted (Fig. 10, not shown), effectively stripping the ply therefrom; (f) and member 132 is retracted, leaving the ply at the receiving station. Separation of single sheets is aided by vacuum means 64, Fig. 1, acting on the edge of a stack.

Title: Improvements in or relating to nuclear reactors
IPC: G21C3/33
Filed: 1962-11-28
Abstract: 963,565. Reactors. GENERAL DYNAMICS CORPORATION. Nov. 28, 1962 [Dec. 4, 1961], No. 45072/62. Drawings to Specification Heading G6C. In a high temperature helium gas cooled reactor, the fuel elements are purged of gaseous fission products by part of the coolant, the fission products passing into containers within the pressure vessel. The spaces in the pressure vessel above the reactor, and between the core and the pressure vessel are in contact with the coolant gas before it flows through the core so as to be maintained at the temperature of the coolant intake and to balance the thrusts of the coolant gas against the core upper and lower surfaces. The core is formed of fuel element clusters and is surrounded by a graphite reflector and steel thermal shields. In one embodiment, each cluster is formed of several elements grouped round a central rod of moderator. Each element comprises a vertical cylindrical container of graphite or bery- 11ia having a low permeability to fission products anda high permeability to helium. Annual shaped fuel pieces are mounted round a central spine of, e.g. graphite. The top and bottom closures of the container are of porous graphite and metal respectively to permit a purge stream of coolant gas to flow through the top closure, down inside the element and out through apertures in the lower closure to a fission product trap. The central rod comprises a graphite tube into which a lifting or reactivity control rods may be inserted. The fuel element clusters may expand vertically upwards at their upper supports. Each fuel piece may be U235, Pu and the fertile material U238, Th. 232 together with a moderator. The fuel particles are carbides, coated with the moderator and the pieces are formed by sintering. In a second embodiment the core is formed of elements similar to those of the first embodiment but the coolant gas flows into and out of the pressure vessel through concentric tubes. Specification 948, 313 is referred to.

Title: Manufacture of multi-groove pulleys
IPC: F16H55/44
Filed: 1974-10-18
Abstract: 1480769 Making pulleys; spinning ASPRO Inc 18 Oct 1974 [19 Oct 1973] 45163/74 Headings B3A and B3J  A multi V-groove sheet-metal pulley, Fig. 4 (not shown), is made from a cup-shaped blank in two spinning operations, two grooves being formed in the cylindrical side wall adjacent the base in the first operation and at least a third groove being formed in the side wall in the second operation. Formed by pressing and trimming operations, the starting blank has a hub 83 and a reinforcing ring 84 both attached as by welding. Apparatus for spinning the first pair of grooves comprises a known machine in which the headstock spindle and possibly also the tailstock spindle are driven and relatively movable axially. The machine is provided with headstock and tailstock dies and rolls for spinning the grooves. A third groove is spun in a second machine similar to the first but with different dies and rollers. The headstock dies for the first machine include a sleeve 13, Fig. 6, on which the blank is supported with its free end 86 lodged in a groove 51. Within the sleeve 13 is a spool 17, 15, 18 formed with radial slots 26, Fig. 13, to receive the shanks 35 of die elements 34 expanded, against the action of return springs 45, by an hydraulically-operated mandrel 54. Springs 22 press the spool towards the tailstock which has ring dies 61, 62, 63 bearing on the blank. During spinning by rolls 72, 73 the tailstock moves towards the headstock, and roll 73 moves into engagement with roll 72, Fig. 7. As the rolls 72, 73 are withdrawn from the roughly-formed grooves 93, finishing rolls 77, 78, Fig. 8, are moved into the grooves and the spool 17, 15, 18 moved by the tailstock against a stop collar 11, collapsing springs 22 and completing the first two V-grooves 99. For the second spinning operation the intermediate blank is mounted on a sleeve 105, Fig. 16, in which there is a spool 109, 107, 110, similar to the spool for the first operation, and carrying radially expansible die segments 125. A single rough-forming roll 159 is used, followed by a finish-forming operation, Fig. 17, in which three rolls 164, 165, 166 are used two of which maintain the shape of the previously-formed grooves and the third 164 displaces a clampsleeve 140 to expose the retained margin of the workpiece during the forming operation.

Abstract: 1355999 Comparators ING C OLIVETTI & C SpA 28 Sept 1971 [30 Sept 1970 26 Aug 1971] 45192/71 Heading G4H In apparatus for digitally comparing a desired dimension F of a member with the actual measured dimension M, further desired intermediate dimensions spaced from the desired dimension by amounts A 1 , A 2  ... are added to or subtracted from the desired dimension F and the resultant dimensions T 1 , T 2  ... compared with the measured dimension M. As described, the desired dimension F relative to a datum is entered as a six digit member and a sign bit by positioning each of six contacts (19, Fig. 2, not shown) on one of ten leads and a further contact on one of two sign leads. The contacts are enabled sequentially by a timing circuit 16 (Fig. 1) to supply the digit to a binary encoder 27. The absolute value of the desired dimension is compared with the absolute value of the measured dimension (detected by a position measurer detecting the position of a tool working the member) in a magnitude comparator 17<SP>1</SP> to supply a signal on lead I or II to a sign comparator 17<SP>11</SP>. In dependence on the relative signs of the actual and desired dimensions either a lamp 29 or lamp 31 is lit. The amounts A 1 , A 2 , A 3  are similarly entered as positive three digit numbers and after encoding to binary form either added to or subtracted from the dimension F in dependence on the output of comparator 17<SP>11</SP>. The outputs T1, T2, T3 of the adder 40 are then similarly compared with the actual measurement to give a signal on one of two leads. During alternate cycles of operations the measured dimension M is compared with the dimension T2 and, in dependence on the relative value of M, F and T2, in the other cycle the dimension M is compared with either the dimension T1 or T3 under the control of logic circuitry 44 (Fig. 4, not shown). The comparator outputs are fed via pairs of gates 69, 70; 58, 59; 71, 72, one pair being enabled in dependence on which dimension is being compared with the measured input, so that an associated lamp X, Y, Z is lit when M>T 1 , M>T 2 , M>T 3  respectively. When equality exists between the actual and desired dimensions both the lamps 29, 31 are extinguished and the tool is stopped. In another embodiment the input may be derived from punched tape. This embodiment also allows incremental values to be entered in place of the intermediate dimension.

Title: A method of continuously casting metals in short watercooled continuous casting moulds

Abstract: 1,070,497. Continuous casting machines. VEREINIGTE LEIGHTMETALL - WERKE G.m.b.H. Oct. 29, 1965 [Nov. 28, 1964], No. 45936/65. Heading B3F. In a method of continuously casting metal in a short water-cooled mould the emergent casting is cooled by pulsating sprays of water or like coolant directed thereon. The pulsations may take the form of spraying periods interrupted by periods in which the spray is completely cut off or of modulations of the spraying pressure. It is stated that by varying the length of these periods, and/or the spraying pressure the surface temperature of the casting can be controlled over a greater range of temperatures than is possible merebly by controlling the quantity of cooling water supplied to the sprays. This is stated to be due to the effect of a protective layer of steam formed at the surface of the casting when small quantities of cooling water are sprayed without any pulsating effect. Air-cooling, either by a steady or pulsating compressed-air supply may be employed with the pulsating water-spray and the casting may be immersed in a water-bath immediately after being spray-cooled.
