Title: Electrical insulation device
IPC: H05B7/00
Filed: 1979-03-16
Abstract: Electrical insulation is provided between two parts of a structure intended for exposure to high temperature radiation from a heat on source, e.g. the interior wall 2 of an electrical discharge furnace, by providing a slot 1 in the structure positioned so that the base of the slot cannot view the heat source 4 directly. The sporadic discharge between the arc electrode 3 and the adjacent part of the insulating wall 2 when its insulating properties are reduced by increasing temperature is prevented, a sporadic discharge occuring instead across the slot 1, The slot may have flared lips, sides generally angled away from each other in the direction of increasing temperature, provisions 9 for a flow of gas in the same direction and provision 8 for cooling the material bridging the base of the slot to a temperature at which it may be electrically insulating. <IMAGE>

Title: Anti-collision vehicle radar system
IPC: G01S13/93
Filed: 1979-04-18
Abstract: An anti-collision vehicle radar system (12) overcomes interference from radar systems on other vehicles by providing a radar transmitter (15) having a transmitting antenna (14) which transmits a radar beam having circular polarization with a particular direction of rotation of the polarization, a radar receiver (18) for receiving the reflected radar beam and including a receiving antenna (16) which discriminates in favour or received signals having circular polarization with the particular direction of rotation but which discriminates against received signals having circular polarization with the opposite direction of rotation.

Title: Elevating nutrient-rich ocean water
IPC: A01K61/00
Filed: 1978-08-21
Abstract: Nutrient-rich water from the aphotic zone of the ocean, which normally begins at about 100 to 200 meters below the ocean surface, is desalinated or partially desalinated in situ using electro-dialysis means (12) while leaving the nutrients in the water. The nutrient- rich desalinated water thus obtained, being of lesser density than the surrounding seawater, naturally rises through conduit (20) into the relatively nutrient-poor photic zone of the ocean and is dispersed therein, thus increasing the concentration of nutrients in the photic zone near the surface of the ocean. This increases the fertility of the near-surface photic zone, and thus increases the supply of harvestable food fish from the near-surface photic zone. <IMAGE>

Title: Method of controlling penetration of dopant into semiconductor devices
IPC: H01L21/22
Filed: 1979-10-10
Abstract: In a method of fabricating a semiconductor device, a region containing a first species of ionised dopant formed by diffusion into a body of semiconductor material, creates an internal electric field which provides a barrier against the penetration of a second species of ionised dopant from a first region into a selected region of the semiconductor body. In the application of the method to the fabrication of a monolithic infra-red charge coupled device comprising detectors 1, ionised dopant is diffused into the semiconductor substrate 10 to render it sensitive to infra-red radiation, and the barrier layer 12, which is formed by diffusion into layer 11 of ionised dopant, serves to prevent the penetration of dopant from substrate 10 into the epitaxial layer 11. <IMAGE>
