Abstract: 1,241,269. Nuclear power plant. BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd., and ENGLISH ELECTRIC CO. Ltd. 18 Dec., 1970 [23 Dec., 1969], No. 62548/69. Heading G6C. The heated gas coolant from the reactor core 10 is supplied via ducts 18 to a number of gas turbine units 15 disposed in respective pods 14 within the thickness of the wall of the concrete pressure vessel 12. The gas returns via ducts 16 and the upstream and downstream sides 20, 22 of the core are isolated from each other by a peripheral seal 24 extending between the core and the pressure vessel wall, this seal having a number of ports 26 normally closed by valves 28. The turbine units 15 generate electricity, the electrical load demand being sensed by a device 34 controlling the valves 28 through mechanical connections 30. Thus, should a rapid reduction in load demand occur the valves 28 are opened by a desired amount so that a proportion of the coolant from the ducts 16 by-passes the core 10 and flows through the ports 26.

Abstract: 1,274,775. Crystallization apparatus. C. O. C. E. I. S.A. and F. LAURENTY. 31 Dec., 1969 [31 Dec., 1968], No. 63468/69. Heading B1G. A device for crystallization by direct contact of a solution with an inert, immiscible heat-transfer fluid comprises a crystallization enclosure 10 containing a plurality of superposed stages A, B, C. Each stage contains a fluidization chamber 11A, B, C which is closed on all sides except at its top 12A, B, C which is perforated. Heat transfer fluid is fed into the chambers and each stage has a collector 21A, B, C for the fluid whereby transfer between stages is effected. The solution is fed in at the bottom and rises through the stages, there being spaces between stages allowing this. As the solution rises crystals form and fall to the bottom for collection. As described the fluid is circulated in countercurrent to the solution via a heat exchanger 26. The chambers may be divided by partitions 14 into spaces 13. A crystal fragmenting device 48 may be provided at the top for controlling the number of crystals to be grown. Chambers 11 may be staggered relative to each other along the height of the enclosure. Crystals of Ca(NO 3 ) 2  may be so obtained from a solution resulting from the extraction of calcium salts from natural phosphate using HNO 3 ; the fluid may then be "white spirit".

Title: Optical fibre connector
IPC: G02B6/36
Filed: 1978-10-10
Abstract: A connector for optical fibres uses the thickness of a piece of metallic foil to space an optical fibre from a known plane and utilises the metallic foil to hold the optical fibre. Two portions are provided each with an optical fibre retained by metallic foil 14 and a third member 16 is used to align the optical fibres in one plane by abuttment against the metallic foil and in a further plane by use of for example a groove.

Patent GB-2055315-A (GB)
Title: Die casting method
IPC: B22D27/11
Filed: 1979-02-14
Abstract: Die casting method in which a molten metal is injected into a die cavity (30) for cast products through a sprue (31) and also applied with pressure by means of a pressure plunger (36) through a pressure channel (17) communicating with the die cavity (30) at a location other than the sprue (31). According to this invention, upon the application of pressure, the molten metal in the pressure channel (17) may be extruded into the die cavity to form an expanded flow so that the application of pressure is always carried out with a stable pressure. A part of the die-cast product solidified in the die cavity (30), which part is substantially opposed posed to the pressure channel (17), is cut along the moving direction of the plunger (36) across a sectional area larger than that of the pressure channel (17), in order to remove a portion where surface defects and or segregation may be apt to grow so that the strength and/or workability of the die-cast products is/are deteriorated. Further, holes or grooves caused by said cutting are used for parts of configuration of products. This method is adapted for the mass production of products such as housings of compressors, pumps and the like, which is to be used under high-pressure conditions or to be subjected to precision working. <IMAGE>
