Patent GB-2174518-A (GB)
Title: Wafer scale integrated circuit
Inventor: CATT IVOR
IPC: G11C29/00
Filed: 1985-04-15
Abstract: An integrated circuit wafer comprises an array of chips (10A, 10B) provided with logic enabling the chips to connect up to each other under the control of commands sent along a forward path through the already connected chips and back through a return path. Growth is attempted in the directions NE, S, W and D, in turn where D is a diagonal direction which is NW for chips 10A and SE for chips 10B. Tests are made as each chip is added to the grown path. Defective chips are avoided by changing the growth direction to select another chip. In order to increase efficiency of growth to include all or virtually all good chips, a form of branching growth is permitted. Growth may take place in more than one direction from a single chip but the path of interconnection remains a single path. More particularly, when branching growth takes place from a chip, the return path thereto is directed into the forward path of another chip whose return path is directed into the return path leaving the chip from which the branching growth has occurred. The potential upstream chips and the potential downstream chips for any given chip from two mutually exclusive groups. For example a 10A chip has potential upstream chips in direction NE, S, W and NW but has potential downstream chips in directions N, E, SE relative to the 10 chip.

Title: Induction motor drive circuits
Inventor: WILLIAMS BARRY WAYNE
IPC: H02P8/14
Filed: 1985-05-20
Abstract: A drive circuit for an induction motor with a pair of antiphase windings (3,4; 5,6; 7,8) associated with each phase of the motor has a d.c. power supply, and a switching arrangement (T3-8, DF3-8) supplying each winding in only one direction, controlled by a frequency control circuit. The switching arrangement comprises a bridge circuit having a first transistor (T3; T5; T7) connected between one supply rail and a first end of one winding (3; 5; 7) of the winding pair, and a second transistor (T4; T6; T8) connected between the other supply rail and a first end of the other winding (4; 6; 8) of the winding pair of the same polarity as the first end of the one winding. Thus only two transistors rated at the supply voltage are required for each phase of the motor. <IMAGE>

Title: Improvements in or relating to a humidity sensor
Inventor: ALLEN DONALD CHARLES
IPC: G01N27/12
Filed: 1985-06-26
Abstract: A sensor for measuring the relative humidity within a closed container electrically comprises a plastics plug 4 screwed into an aperture in the wall 1 of the container and projecting into the container. An electrical connector 10 sealingly fitted in the plug provides socket contacts on the outside of the container, and, on the inside of the container, two metal prongs 12, 14 between which a band 16 of salt- impregnated tape is stretched, The humidity within the container is measured by measuring the electrical resistance between the prongs 12, 14. A water vapour permeable membrane in the form of a cover 18 of silicone rubber is fitted over the inner end of plug 4 to enclose the prongs 12, 14 and band 16. The cover 18 serves to render the sensor relatively insensitive to short term variations in humidity which need not indicate exhaustion or failure of a desiccant used to keep the relative humidity within the container low, but may arise from a temperature charge, for example. <IMAGE>
