Title: Improvements relating to wafer scale integrated circuits
Inventor: WESTMORE RICHARD J
IPC: G11C29/00
Filed: 1985-09-30
Abstract: The drawing represents part of an integrated circuit wafer comprising modules represented by the squares, including defective modules denoted by a cross. The modules include configuration logic which enables them to be grown into a chain of good modules. The line (24) extending through modules (20 to 23) represents part of a maximum length chain which has been grown by use of a first algorithm which adds modules to the chain, tests them one by one, discards them if they are defective, tries new test directions and retracts the chain by backing out of modules when no new directions are available. The algorithm adopts the longest chain which it finds. Broken lines (25 and 26) indicate branches through good modules which have been backed out of during the course of finding the longest chain. A second algorithm is employed to find good modules (26) which have been backed out of but which can be brought into the chain by a deviation thereof as indicated by the U shaped line (27). The second algorithm enables the length of the chain to be increased, i.e. the efficiency of incorporation of good modules is increased.

Title: Safety system for iaser-utilising facility
Inventor: EDWARDS STANLEY ALFRED
IPC: F16P3/00
Filed: 1986-02-24
Abstract: A laser beam-utilising facility is provided within a screening arrangement (22) which is opaque to infrared radiation but may be transparent to visible light. The screening arrangement is externally monitored by an infra-red sensor (18) which may be of a fixed or scanning type.

Patent GB-2177816-A (GB)
Title: Photographic reproduction
Inventor: BALL FRANCIS DENNIS
IPC: G03F3/00
Filed: 1986-07-17
Abstract: A monochrome picture is produced by printing in different prime colours using plates prepared by a photographic process. An original picture is first screened to obtain a dot image with the desired contrasts. The parameters that give this, such as aperture and exposure time, give data for the printing plates. In one method, the original picture is screened again for each of the prime colours, each time with the parameters proportioned in accordance with the contribution to be made by the respective colour. The dot image plates or films are then used in known manner to prepare the printing plates. In another method, the plates can be prepared without this intermediate stage, by means of making plates or films photographically using information from the first screening.

Title: Nuclear reactor-based power source
Inventor: TAN WILLIAM PEK SENG
IPC: G21D5/02
Filed: 1987-07-28
Abstract: A nuclear reactor-based power source operates on a closed Brayton Cycle using helium or helium/xenon coolant gas with a particle fuel reactor 18. The reactor 18 is selectively operable to provide different output modes, one of which involves the production of relatively short duration, high energy output bursts. The power source is provided with thermal storage materials having a range of melting points and high latent heats of fusion so that large amounts of waste heat can be absorbed during the burst mode of operation. The reactor 18 has a selectively operable radiator 47 associated with its coolant circuit so that the extent of waste heat dissipation can be varied according to the mode of operation of the reactor 18. Heat pipes 44 couple waste heat to the radiator 47. The core comprises circular fuel rods each containing enriched fuel particles dispersed between concentric porous tubes of a frit material (Fig. 5A, not shown). Tube core is surrounded by an annular reflector in which rotatable drums of reflector material are arranged, each drum including a peripheral sliver of neutron absorber for control purposes (Fig. 5, not shown). Additional control is provided by a central control rod comprising a neutron multiplier section and a neutron absorber section. <IMAGE>
