Title: Improvements in or relating to refuelling machines for nuclear reactors
Inventor: LONG EVERETT
IPC: G21C11/02
Filed: 1959-01-29
Abstract: 897,452. Handling nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 22, 1960 [Jan. 29, 1959: June 3, 1959], Nos. 3295/59 and 18958/59. Class 39(4). The base 10 of a reactor refuelling machine comprises shielding 12 built up of blocks 39a..39d, the blocks 39a, 39b being hinged at 40 to the remainder of the shielding to permit access to the enclosed space, such access permitting manual coupling of the machine hoist (not shown) with an assembly including fuel elements. A recess 13 around the underside of the blocks receives verticallymovable shielding 14 which may close the space between the bottom of the machine and the reactor charge face 36. The shielding 14 is in two parts 41, 141, extending, respectively, beneath the blocks 39a, 39d, the part 41 being raised by a handle 44 and gearing 43. Interlocks are provided to prevent operation of the machine with the blocks 39a, 39b in the open position and a further interlock prevents closure of the blocks 39a, whilst an operator is within the machine. Specifications 873,858, 897,448 and 897,454 are referred to.
Patent GB-164414-A (GB)
Title: Improvements in or relating to the manufacture of hair-pins or other articles formedby bending and shaping cylindrical blanks
IPC: B29C53/08
Filed: 1920-02-03
Abstract: 164,414. Percival, S., (Viscoloid Co.). Feb. 3, 1920. Pins, dress and like. -In making hair pins from cylindrical blanks the blanks are transferred from a hopper to a heating table, along which they are rolled and from which they are transferred one at a time to centering guides, from which they are moved by dies which bend them to shape. The blanks 20, Fig. 4, are fed from a hopper 21 with converging walls by a number of spaced felt-covered segmental discs 41, which are mounted on a shaft 40, Fig. 2, oscillated through levers 39, 38, 37 bv a cam 35 on a shaft 34 driven from the main shaft 25 by gears 33, 32, 31, 29, 28, 27. The blanks are then rolled along the steam table 22 by a reciprocating plate 56 with a felt or rubber bottom so as to prevent warping of or to straighten the blanks. The plate has two pairs of bars 55 resting on corresponding cams 54 on a pair of shafts 53, 59 connected together by links 60. The shafts 53, 59 are oscillated to lift the plate by a cam 45, Fig. 8, on the shaft 30 engaging a spring-retracted lever 47 so as to force a projection 50 carried thereby into contact with an arm 52 on the shaft 53. When the plate is raised it is forced rearwards by a cam 63 on the shaft 34. It then falls and is pulled forward by a spring while in contact with the blanks to roll them along the table 22 one by one down an inclined wall 67 into a notch 24 in a roll 23, Fig. 4, which is oscillated to transfer the blank under a guard 69 on to a guide 68 from which it drops on to the table 71. The roll is oscillated by a rack bar 77, Fig. 2, passing between a pinion 79 in the roll shaft, and a guide roll 78, the bar being connected to a lever 76 operated by a cam 74 on the shaft 73. The ends of the blank are received in recesses in pivoted arms 107 with inclined side walls 105 and an inclined end wall 106 so as to centre the blank. The arms are held in their raised positions by projections 108, thereon engaging the pivoted benders 97, but drop by gravity when the benders move forward to bend the blank round the formers 98, 99, 100. The benders 97 are mounted on shafts 95 provided with spiral springs so that the benders are normally in their inoperative position. The shafts are provided with pinions and are oscillated to perform the bending operation by a pair of rack bars 92 operated by cams 90, Fig. 4. The blank is shaped round the pin 98 by a spring-pressed die 115, mounted on a rod 113 which is retracted by a cam 110. The completed article is pressed through the opening 102 by the head 87 of a plunger 84 which is pressed by a cam 80 against the action of a spring 86. The article is cooled by water passages 120. The shaft 30 is mounted on a casing 118 containing lubricating oil and provided with a drain 119.

Title: Improvements in or relating to sheet feeding mechanism for printing machines
IPC: B65H3/08
Filed: 1926-02-05
Abstract: 265,380. Linotype & Machinery, Ltd., Shuttleworth, J., and Worrall, T. Feb. 5, 1926. Sheet-separators.-In sheet-feeding mechanism for printing-machines of the kind in which the sheets are separated by a suction lifter 1 provided with devices for raising and lowering it and tilting it during the vertical movement, the devices are simultaneously adjustable as a single unit transversely of the feed board. The holder 24 of the lifter 1 is pivotally mounted by studs 2 in a fork on the end of a rod 3 carried by a frame 4 which is reciprocated vertically by a cam 5 splined to a shaft 7, along which the frame and its associated parts are adjustable as a single unit. These parts include a bracket 13 and a cam 17 connected to the cam 5 and movable therewith. The frame 4 straddles a guiding shaft 8. The cam 17 operates to give a tilting movement to the lifter 1 by acting on a roller 16 on a lever arm 15 connected to a rod 10 provided with a plate 22 for acting on a stud 23 on the holder 24 in which the lifter 1 is mounted. The extent of the reciprocation of the rod 10 is governed by a stop 19 and screw 20, and the rod moves in guides attached to the bracket 13. In addition to the transverse adjustment of the lifter 1, it may be reciprocated in a longitudinal direction by means of a link 25 and a lever 26 splined to the shaft 8, which is oscillated when longitudinal movement of the lifter 1 is required. Clips 27 on bracket 13 engage a boss 30 on the lever 26 to cause the lever 26 to move transversely with the rest of the mechanism.

Abstract: 964,737. Weighing apparatus. FREDERICK PARKER Ltd. Jan. 31, 1963 [Jan. 31, 1962], No. 3766/62. Heading G1W. [Also in Division F2] An air valve (see Division F2), rotatable by a trip rod 21, has two actuated positions wherein an inlet A and outlet B are connected together whilst an exhaust passage 25a is isolated, these two positions being defined by diametral ducts 15, 16 in the valve member which intersect at right angles and co-operate with aligned inlet and outlet passages 24a, 25a in the body. Rotation of the valve member in opposite directions from the position shown to align one or other of the ducts 15, 16 with the passages 24a, 25a brings the rod 21 against one or other of two stops 22, 23. The device is adapted to be slidably mounted and locked by a screw 5 on the weighing scale of the hopper fed weighing apparatus disclosed in Specification 907,134, the position being indicated by a pointer 6. Inlet A may be connected to a compressed air supply and outlet B to one end of the reversing valve controlling the pneumatic door closing unit. As the weight of the material increases in the weigher, the pointer 32 moves until, at the preset weight, it turns the trip rod 21 in either direction to initiate, through the reversing valve, the closing of the bin door. This movement may allow air pressure to reach a connection C and act on a resetting piston 20 of the valve. The space 8 surrounding the outer end of this piston is vented to atmosphere.
