Abstract: 1457446 Microprogrammed cash register DSO "IZOT" 10 Dec 1973 [10 Dec 1972] 57199/73 Heading G4A A microprogram controlled cash register has a magnetic core store providing both working and microprogram storage and a data preservation device activated in response to faults. The core store 1 is arbitrarily divided into two parts storing working data and microprograms, the parts being addressed by a microprogram address counter 3 and an address register 9 in conjunction with an access device 4, the data &c. being read out into register 8. Instructions are fed in via a keyboard input device 19 and are executed by a corresponding microprogram. Six microprogram control registers 10-15 are connected as shown with a microcommand decoder 2, a binary/binary-decimal arithmetic unit 17 (binary for microcommands and binary-decimal for data) and a comparator 16. The system also includes a printer 21, display 22, and a transfer device 18, e.g. for connection to a remote processor. A sensor 6 detects faults, e.g. power failure or excessive temperature, and causes an "interrupt" microprogram to be activated to store the address counter and various other register contents and to switch off various supply voltages in a fixed sequence, the power for this purpose being derived in the case of a power failure from the energy stores within the system. When the power is restored or the system is otherwise switched on the system is reactivated, the voltage supplies being switched on in the correct sequence, controlling timing oscillator 7 being activated, and the various register contents restored to allow the operation to continue from the point of interruption.

Title: Nuclear Fuel-Element
Inventor: LASS JAMES LLOYD
IPC: G21C3/16
Filed: 1966-12-28
Abstract: 1,173,928. Fuel elements. GENERAL ELECTRIC CO. 28 Dec., 1966 [26 Jan., 1966], No. 57996/66. Heading G6C. A fuel element comprises nuclear fuel 50 housed in an elongated cladding tube 45, the upper end of which includes a plenum chamber 54 to collect fission product gases, with welded end plugs 46, 48 sealing the ends of the tube, at least one thin metal wafer, e.g. wafers 102, 102<SP>1</SP> being disposed between the fuel and the lower end plug 48 to provide thermal interfaces both between the fuel and the wafer(s) and between the wafer(s) and the plug to reduce the quantity of heat transferred from the fuel to the plug 48 and thus prevent excessive stresses from being formed in the welded connection between the plug 48 and the cladding tube 45. The two thin metal wafers 102, 102<SP>1</SP> are triangular and have rounded apexes, one wafer being displaced through 60 degrees with respect to the other. The cladding tube is preferably made of Zr and the wafers of Zr or stainless steel. The use of triangular wafers is particularly advantageous in that when such wafers are inserted into the upper end of the cladding tube, which is tilted so that the wafers ride down the tube, they invariably come to rest flat against the face of either the end plug or another wafer which has already been inserted. Circular wafers, for example, when inserted in this manner frequently come to rest on their edges at the bottom of the tube. A fuel element assembly (Fig. 1, not shown) is described comprising a plurality of fuel elements of the above construction.

The control mechanism may include two concertina-type bellows each attached to the same piston at one end and plate 3 at the other, the respective bellows being inflated or deflated so that the piston actuates said second arm. The whole of plate 3 may be rotated by motor 31 and gear 32 so that successive layers of materials 35 and 35' may be deposited, covers 11 being closed while deposition is not required, and a piezo-electric deposit-thickness measuring device may be used. Dish 2 may be provided with O-ring seals so that with the substrate in place and cover 11 closed, the dish may be evacuated via a hole 23 Fig. 1 (not shown) before insertion into apparatus 30, which may then be evacuated without the risk of dust contamination of the substrate during pumping.

Abstract: 1,253,816. Mudguards. R. CUEVAS. 12 Dec., 1968 [22 Dec., 1967; 21 Oct., 1968], No. 59135/68. Heading B7J. A vehicle wheel mud flap comprises a flap portion 11 attachable to a vehicle wing 6 by means of a ball-and-socket joint formed by two substantially trapezoidal jaws 1, 2 each having a concave part and a flat base part with a U- shaped spacer 8 placed between the jaws, and screws 4, 5 passing through the jaw 1 and one leg of the spacer to bear upon the other leg, thus clamping the wing 6 between two flat surfaces. A square hoop 3 acts as a retaining pivot so that when the screws 4, 5 grip the edge of the wing 6 the ball 7 of the joint is gripped between the concave parts of the jaws 1, 2. The ball 7 is mounted on a tube 9 in which is fitted a bead 10 on the flap portion 11. In a second embodiment (Fig. 3, not shown) lugs are situated on the leg of the spacer where the screws bear such that when the screws are tightened the lugs grip and slightly punch the wing. Also in this embodiment an inwardly projecting lug is mounted on a jaw which lug will penetrate slightly into the ball. Moreover the flap portion has slots connected by screws to an arm carried by the ball.

Abstract: 1,208,649. Valves. LOKVAL (PTY.) Ltd. 12 Dec., 1968, No. 59156/68. Heading F2V. A float-controlled valve including a hollow body 10 having an inlet 16 and an outlet 20, a displaceable valve element 54 seating on the inlet side and being connected to a piston 50 on the inlet side and an axially ported member 58 on the outlet side; a cylinder 36 in which the piston 50 is sealingly slidable; a float-operated actuating lever 30 pivotally mounted on the body 10, and a biased member 90, 92 associated with and movable within limits relative to the actuating lever 30 and adapted to engage the ported member 58 to maintain the open position of the valve until the actuating lever 30 has returned to substantially a normal position; the arrangement is such that with the valve element 54 off the valve seat the valve is open in full bore whereas the opening and closing of the valve is substantially instantaneous. The actuating lever 30 provides a screwthreaded socket 82 into which the float carrying arm is screwed. The lever 30 pivots about a pin 68 to alter the position of the pair of arms 90, 92 carried on the pivot pin 68. The load arm portion 28 of the lever 30 extends to a bar 78 of member 72. In operation, fluid under pressure enters the inlet 16, flows through the hole 66, the ports 102 to the outlet 32. The spring 70 produces a downward pressure on the piston 50 but the movement is blocked by virtue of the rim of the member 58 resting on the arm 90 (Fig. 2, not shown). As the liquid level rises, the lever 30 is rotated anticlockwise whereupon, at a predetermined level of liquid, the set-screw 100 engages the arm 90 and causes it to rotate in an anticlockwise direction. Eventually the arm 90 no longer acts as a strut and the valve element 54 and member 58 travel rapidly downwardly to close the valve (Fig. 1).

Abstract: 602,004. Photo-electrically testing dimensions. HURLEY, S. C. July 12, 1945, No. 17816. Convention date, July 17, 1944. [Class 40 (iii)] To test the dimensions of a rounded article, e.g. a cylinder, it is viewed by photo-electric cells while being rotated. The articles 10, Fig. 1, are fed forward, along a V channel, to be engaged by rotating members 1, 2 which are periodically lifted by the action of cam 19 to release the tested article. The article under test is rotated by member 2 against a stop, and is viewed by cells 38, Fig. 6, to test its diameter and by cells 39 ... 42 to test its length ; the dimensions are correct if cells 38, 39 and 42 are unilluminated while cells 40, 41 are illuminated. The cells may be placed to test the dimensions of hour-glass shaped articles, Figs. 2 and 8 (not shown) ; bevelled cylinders, Fig. 9 (not shown) ; cones, Fig. 11 (not shown) ; and the trueness of end faces of cylinders, Fig. 10 (not shown). In a modification, the rotating members 1, 2 are pressed downwards by springs, Fig. 4 (not shown). The light from a source 60, Fig. 13, may fall on a suitable mirror 63 co-operating with cells 64, 65 to produce a magnified effect. Several such mirrors may co-operate with other cells to test other dimensions, Figs. 16 ... 19 (not shown). The cells 64, 65, Fig. 15, may be connected in a bridge to control a thermionic valve 78 to actuate compressed air valves to eject the tested article from the V channel into other testing zones or into appropriate containers ; cells 79, 80 testing another dimension are similarly connected, and relay 76 operates when the article satisfies both tests ; further cells 82, 83 may be added to test a further dimension.
