IPC: F42B33/00
Filed: 1925-07-21
Abstract: 257,389. Greenwood & Batley, Ltd., and Barker, J. H. July 21, 1925. Projectiles, making.-Apparatus is provided for distributing bullet jackets and cores into recesses in trays and causing the cores to be fed into the jackets. As shown, a number of rocking platforms 49, Fig. 1, are arranged on trunnions 16 on a table 5, the rocking movement being transmitted to the trunnions 16 by levers 21, hooked links 22, levers 20, and horizontal bar 31 connected by an eccentric pin 38 to a disc 40 on a shaft 41 driven by a belt. A hopper 52 is detachably mounted on each rocking platform. The hopper has a conical upper part tapering to a tubular chamber 51, Fig. 7, covered by a fixed tray 56 and open at the bottom for the reception of a free tray 62. A quantity of bullet jackets is placed in one of these hoppers, with an empty tray 62 in its base, and the hopper secured by bands 88 or otherwise on a platform 49. The corresponding hooked link 22 is then swung about a pivot 28 on the lever 20 to make its notch 23 engage a pin 30 on the lever 21, whereupon the platform receives the rocking motion. This causes the jackets to fall point first through holes in the fixed tray 56 into recesses in the tray 62. These trays are then removed, and any vacant recess filled by hand. Meanwhile, a tray 65, Fig. 16, is placed in a box 64, aluminium core tips 2 are spread over the tray and find their way individually base downwards into the holes of the tray, and the box is then closed by means of a side-piece 69, a sliding drawplate 67, and the lid 68. The box is then turned upside down by hand or by means of a cage 76, Fig. 30, into which it is inserted, the cage being mounted on trunnions 77 nearer one side to facilitate the swinging over. The inverted box and its lid are then removed, leaving the tray 65 with the tips 2 resting on the drawplate 67. This assemblage is placed over the tray 59, Fig. 22, previously loaded with jackets 3, an empty tray 66 being interposed provided with flared holes for accurately positioning the jackets and guiding the tips into them, when the drawplate 67 is pulled out. The tray 59 with the jackets and tips is then put in the chamber 51 of a hopper 52 filled with lead cores, which, when the hopper is rocked, pass through the holes in the fixed tray 56 and fall into the jackets in the tray 59 below. The parts are then assembled as shown in Fig. 27, and can be pressed to the completed shape, Fig. 29, by any known method. The lead cores 1 are made cylindrical with hemispherical ends 85, which are deformed in the pressing operation.

Title: Nuclear reactor fuelling installation
IPC: G21C13/067
Filed: 1969-04-14
Abstract: 1,260,684. Fuelling reactors. ATOMIC ENERGY OF CANADA Ltd. 14 April, 1969 [15 April, 1968], No. 18965/69. Heading G6C. The Specification relates to the fuelling arrangement disclosed in Specification 1,260,682 and gives further details of the stop mechanism W disclosed in Specification 1,260,685. As shown, the piston 286, which is driven by differential pressure applied to passages 288, 289, moves the rod 308 to the left to pivot detents 280, 281 about a pin 282 to grip a protruding annular ridge 293 formed on a member 253 situated at the lower end of a fuel element string 253 and thus prevent movement of the string along its longitudinal axis. To prevent unwanted movement. of the piston 286 to the right to release the grip on the ridge 293 in the event of failure of the fluid supply to the passages 288, 289, an auxiliary locking piston 500 slidable on a fixed member 503 is biased by a spring 501 against a stop 507. A spring collet 502 having resilient fingers 504 is connected to the piston 286 so that when the piston moves to the left the ends of the fingers displace the locking piston 500 to the left and noses 505 on the fingers ride over a shoulder 506 on the fixed member 503. The piston 500 then retracts to lock the fingers 504 to the member 503 as shown. When differential pressure is admitted to the passages 288, 289 to release the detents 280, 281 the pressure first moves the locking piston 500 to the left to release the fingers 504 and then moves the piston 286 to the right. A rack and pinion gear 510, 511 driven by a coupling 310 attached to the rod 308 gives an indication of the-position of the detents 280, 281 by a potentiometer 512.
