Title: Thermal control material
IPC: B32B7/025
Filed: 1980-11-05
Abstract: A multiple-layer material for use e.g. as thermal blankets on spacecraft includes inner and outer thermally insulating layers (1, 2) and an intermediate electrically conductive layer (3), the outer insulating layer (1) having a thickness such that many of the bombarding electrons will come to rest at or near the conductive layer and the resulting charge be conducted away. The material may comprise flexible plastic inner and outer layers or be in the form of glass tiles. Material is also usable in other situations where electrical charge build-up may be a problem, e.g. for insulating explosive liquid containers. The electrically conductive layer e.g. Al, could be coated on one of the thermally insulating layers by vacuum deposition, prior to the other such layer being stuck on by an adhesive, or the two thermally insulating layers could be stuck to one another by a layer of adhesive loaded with conductive metal (e.g. Al or Ag) powder. An optional further conductive layer (4) may be applied to the outside of layer (2). <IMAGE>

Patent GB-2097121-A (GB)
Title: Directional acoustic receiving array
IPC: G01S3/80
Filed: 1981-04-21
Abstract: An acoustic telescope (Fig. 1) comprises an array 9 of omnidirectional microphone transducers 10 signals of which are delayed by different amounts in delay elements 13 by a microprocessor 14 which forms a directional reception beam for the array. The signals on each microphone channel are split into a number of bands by filters B1....Bm and corresponding band limited signals from all channels processed band-by-band in processing means PB1, PB2 etc. in which the signals are subject to amplitude shading (20) or pattern multiplication (23) to increase or decrease respectively the received beam width in relation to the desired beam width. At frequencies above that for which the desired beam width is natural the beam is broadened and for those below narrowed to equalise the beam widths for all the band limited signals irrespective of frequency. The signals are mixed at 26 to provide a real-time audio output of sources only from within the region of the desired beam width. Microphone signals may be recorded for replay and a different beam pattern imposed on them. Multiple arrays may be combined to define a beam in more dimensions. The acoustic telescope may be employed in a reconnaissance system (Fig.3, not shown) in which the transducer signals are transmitted to a ground station where beam forming, processing and listening are controlled and take place. <IMAGE>

Patent GB-2104326-A (GB)
Title: A pulse generator
Inventor: RICHARDSON ROBERT
IPC: G01S7/282
Filed: 1981-08-08
Abstract: A pulse generator is operative to produce a series of very short, high energy pulses by allowing a reactive network to charge periodically from a d.c. power supply over a relatively long interval, and then rapidly discharging the accumulated energy into a load. The generator is intended for use in a radar transmitter. The peak level to which the reactive network charges is dependent on the charging period, and the invention enables the peak level to be controlled by charging the network via an inductor, and allowing the inductor current to build up to a substantial level before charging of the network commences. When the inductor current reached a required level, it is diverted to the reactive network. In this way a series of high power pulses having uniform peak levels is generated in a very convenient manner. <IMAGE>

Title: Stabilizing element
IPC: B63B43/14
Filed: 1981-09-30
Abstract: Semi-submersible platform structures for drilling for natural resources in pelagic areas may be equipped with so much fixed equipment at deck level that their stability becomes insufficient. In order to improve the stability, such a platform is provided with one or more stabilizing elements (6) which are placed aft on the platform. The stabilizing element (6) extends between a submerged buoyancy body (1) of the platform and its deck (4) and has a constant cross-section up to the deck (4). For example, it can comprise a cylinder (7) with a tapering lower portion (9). The connection between the lower portion (9) of the element (6) and the buoyancy body (1) can have a connection (13) which is arranged to rupture before the buoyancy body can be damaged should the stabilizing element (6) be subjected to strong collision forces. The stabilizing element (6) can be connected at the top to the deck (4) of the structure by means of a connecting link (8) which permits a certain resilient rotation about horizontal axes. <IMAGE>

Title: Control method for liquid waste processing
Inventor: HORIUCHI SUSUMU
IPC: C02F1/66
Filed: 1982-04-14
Abstract: In processing liquid waste using a demineraliser resin, e.g. in the condensate treatment stage of a nuclear power plant, the timing of the regeneration of the resin is predicted by measuring the electricity conductivity of the waste after it has been demineralised. The time at which there will be liquid waste produced by the resin regeneration system can therefore be estimated and the probable amount assessed. This waste is to be passed to at least a pair of collector tanks and from there processed, e.g. by evaporation, and stored to ensure there is no delay in regenerating the demineraliser resin, the available space in the collector tanks is measured and the waste passed to the processing stage at a time and in an amount such that sufficient collector tank space is available at the estimated regeneration time. An appropriate control system is used.

Title: Trailer/launching apparatus
Inventor: FISHER ERNEST ENOS
IPC: B60P3/10
Filed: 1983-05-05
Abstract: A boat trailer 1 has variable buoyancy units 3a, 3b, 3c and 3d so that the buoyancy of the trailer may be raised before the trailer and boat are launched into the water and so that the trailer floats with the boat. The buoyancy of the trailer is then lowered by lowering the buoyancy of units 3a, 3b, 3c, 3d until the trailer sinks leaving the boat floating on the water. The buoyancy units 3a, 3b, 3c, 3d may be connected to any convenient pressure source and, for example may be connected to a compressor driven from a vehicle engine. In an alternative embodiment a standard trailer and boat may be driven onto variable support means 41 located at a launching site and the variable support means operated to lower the boat into the water whilst allowing the trailer to sink in a controlled manner. The trailer/launching apparatus may also be used to retrieve a boat from the water. <IMAGE>
