Patent GB-2130412-A (GB)
Title: Electronic money purse
Inventor: HALPERN JOHN WOLFGANG
IPC: G07F7/08
Filed: 1983-02-21
Abstract: The essence of the invention is a socalled "data bit variable spacer generator", block 79 which contributes to the generation of a control output "c" from a combinatory logic circuit group 78. The logic level of "c" determines whether a clear data bit from buffer 82 is to be sent or a random bit from block RMG. The 'variable data bit spacer generator' is controlled by a number of parallel bit outputs from registers SH1 and SH2 which hold a cipher key after being conditioned by other logic inputs derived from key parity flip flops (FF1 and FF2) and clear data bit levels from block 81. Registers SH1 and SH2 shift and recirculate when the c - output is high. Similar principles are used when data are deciphered. The circuit is suitable for integration with other functions on a single substrate chip. <IMAGE>

Title: Nuclear reactor having a shutdown device reacting in dependence upon the neutron flux
Inventor: GERWIN DR HELMUT
IPC: G21C7/107
Filed: 1983-06-10
Abstract: A nuclear reactor shutdown system responsive to neutron flux level consists of a heat sensitive operating element (18) and a substance reacting with neutrons to generate heat and, under excess neutron flux, cause the element to operate. In the invention the response to neutron flux is stabilised against consumption of the substance by reaction with neutrons. This is done by use of a substance which reacts layerwise, or by use of a mixture of fissionable and fertile substances. <IMAGE>
Patent GB-2119427-A (GB)
Title: Handling apparatus for pipe and other tubulars
Inventor: FRIAS ROBERT
IPC: E21B19/15
Filed: 1981-11-20
Abstract: An apparatus for transferring tubulars between pipe racks (R) and a drilling rig floor including a stationary trough (54) located below and extending towards the drilling rig (D) and a movable trough (60) aligned with the stationary trough having one end (62) supported on the drilling rig floor and the other end (64) powered to move between a lower position for transferring pipe to and from the stationary trough and an upper position for transferring pipe to and from the drilling rig floor. Two pairs of legs (190, 192) extending between pipe racks and the stationary trough are provided. Chain driven lugs (194, 196) driven by a single shaft (210) engage a length of pipe and carry it along the length of the legs. A portion (80) of the stationary trough in the loading location is caused to tilt between a tilted position for accepting pipe from the loading legs and a level position flush with the rest of the stationary trough whereby pipe may easily slide to and from the movable trough. A fluid actuated cylinder (244) having a ball and socket mechanism (246, 249) mounted on a lift plate (251) at one end of the cylinder is mounted underneath the apparatus at its center of gravity. The cylinder is extended, the lift plate engages a truck bed lifting the apparatus and the apparatus is pivoted about the ball and socket mechanism until the apparatus is aligned with the desired location and powered winches (w) drag it into position.

Title: High pressure chambers
Inventor: BURROW REGINALD EDWIN DOWNTON
IPC: B63C11/32
Filed: 1983-07-28
Abstract: A high pressure chamber, for example for simulating conditions in deep ocean, comprises a cylinder (6) within which there is the hollow interior (4), of the chamber, and a closure member (24) for closing an opening of the chamber interior, the chamber further comprising locking elements (26) which are movable between a release position, in which they are disposed outwards of the periphery of the closure member (24) to allow the closure member (24) to be removed from the opening, and a locking position, in which they engage edge regions of the closure member (24) to prevent removal of the closure member (24) from the opening, the locking elements (26 or 42) being operable by control members (32) which extend through the wall (6) to actuating means (30) disposed at or adjacent the exterior of the cylinder (6). In this high pressure chamber, because the locking elements, which may be additional to or part of the control members, are operated from the exterior of the cylinder, neither the locking elements themselves nor the actuating means obstruct access to the hollow interior of the chamber when the closure member is removed. <IMAGE>

Title: Ultrasonic wire bonder and method of manufacturing a semiconductor therewith
Inventor: ARDERN WILLIAM
IPC: B23K20/00
Filed: 1985-07-08
Abstract: The bonder is provided with a single bonding head 10 which has two bonding wedges and grooves for location of wires W1, W2 under the wedges and two guides through a tongue 10A at the rear of the bonding head. It is used to perform the simultaneous bonding of two connecting wires on the contact area 2 of a semiconductor device 3 and on a conductor 5 associated with the contact area. The bonding time required for two wires of a given diameter is the same as that required to bond a single wire of the same diameter, thus twin connecting wires may be provided in half the bonding cycle time and the wire spacing is accurately determined without operator intervention. The bonder is of particular use in the manufacture of triac devices where the wires can be accurately spaced one over a first sector, the other over a second sector of the triac structure, on a contact area common to both sectors of the triac. <IMAGE>

Title: Radio control bait and tackle dispenser
Inventor: DUGGAN KEVIN
IPC: A01K97/02
Filed: 1988-01-28
Abstract: The Radio Control Bait And Tackle Dispenser has a body 1, propelled along by propeller 29, the speed of which can be varied through a radio control set (not shown). A container 2 can be elevated and lowered to allow bait to be off-loaded into the water. The speed and distance of elevation and lowering also being controlled through the radio control set. Two terminal tackle trays 3 allow up to two sets of terminal tackle to be conveyed to a required water location with or without a loaded container. The said terminal tackle can be off loaded into the water by the application of line pressure by the angler when the required location is reached. The container bait and terminal can thus be made to assume close positons on the water bed. <IMAGE>
