Title: Superplastic forming of sandwich panel
Inventor: TSUZUKU TAKAYUKI
IPC: B21D26/059
Filed: 1992-12-18
Abstract: A method for making a metallic sandwich panel, in which the cost of the forming dies is reduced relative to prior art methods, machining to adjust the sheet thickness of the face sheets after shaping is avoided, freedom in the design of the panel is made possible, and panels having smooth outer surfaces can be produced.

Title: Self routing optical switch
Inventor: EVERARD JEREMY KENNETH ARTHUR
IPC: H04Q3/52
Filed: 1993-02-19
Abstract: A self routing optical switch consists of a non-linear material 1 surrounded by an array of reflecting or semi- reflecting mirrors or surfaces 3, 4, 5. These reflecting surfaces reflect some light from the non-linear material back to the non-linear material. An optical signal beam or optical data packet incident on the non-linear material is routed to a selected reflecting surface by including the destination address in the optical signal in the form of the autocorrelation function of the optical signal. The destination is selected by arranging for the round tip propagation time between the non- linear material and the semi-reflecting surface to be equal to the time delay between any two peaks in the autocorrelation function. The address and hence autocorrelation function can be changed by varying any combination of the amplitude, phase, frequency or polarisation of the optical signal. This routing information could be in a header or in the data itself and could be removed afterwards if required. This system has the capability to route most of the input signal down the wanted route. A holographic grating may be used to direct light between the reflecting surfaces and the non-linear material (Figures 8-14). <IMAGE>

Patent GB-2275770-A (GB)
Title: X-Y position based on reflected light
Inventor: TIBAZARWA AUGUSTINE KAMUGISHA
IPC: G06F3/033
Filed: 1993-03-04
Abstract: A bounded region 1 has a light source and a light reflective and sensitive boundary. The rays of the source may be made to take a definite (deterministic) path, and thus produce a deterministic light intensity profile on the light sensitive boundary. Thus an opaque object placed in the rays' path, will alter the expected intensity. By comparing the expected and the measured intensity profiles of the sensor, the straight line containing the opaque object can then be established. A second light source producing a second beam will give a different straight line, and the spatial intersection of these two lines is thus the X-Y position of the object. By appropriately switching on/off the two sources, it should be possible to minimize interference. <IMAGE>

Title: Domestic hot water heating system
Inventor: GLEDHILL HOUGHTON AINSWORTH
IPC: F24H9/12
Filed: 1993-09-03
Abstract: In a storage water heating system, pressure relief is provided by a pressure relief valve unit 16 which is combined with the float control means which controls the inflow of cold water into the system via a feed and expansion tank 12. The pressure relieved water is prevented from flowing into the feed and expansion tank and is discharged to waste e.g. via the feed and expansion tank overflow 56. Alternatively, a pressure relief valve 60 communicates with the overflow 56 via a pipe 62. Excess pressure may arise downstream of a non-return valve 52 due to heating of mains pressure secondary water by a heat exchanger 42 within the hot water storage tank 10. <IMAGE>

Title: Radar
Inventor: RICHARDSON MICHAEL RICHARD
IPC: G01S13/34
Filed: 1993-11-06
Abstract: A homodyne FMCW radar, suitable for mounting on a vehicle for collision avoidance or cruise control, emits a single cycle of "up-sweep" 30, "down-sweep 32 then constant frequency 36 from each of a plurality of antennas (16, 18, 20, fig 1) in turn. During periods of constant frequency, the beat signals from the up-sweep and the down-sweep are Fourier transformed separately, and peaks in the resultant spectra are tracked independently. Estimates of target velocities are obtained from the rate of change of frequency (assuming constant velocity), whence target range can be obtained from frequency. Finally ranges and velocities obtained from the up-sweep can be associated with those from the down-sweep. Effects of acceleration can be incorporated to improve the association. This enables a low false alarm rate to be achieved, even in the presence of a large number of targets, range-Doppler ambiguity, intermittent returns or high noise. Digital signal processor 26 also receives speedometer and steering signals, and controls engine power, brakes, etc. <IMAGE>

Title: Polymeric articles and materials
Inventor: TAYLOR PAUL ANTHONY
IPC: B29C48/10
Filed: 1993-04-23
Abstract: Improvements in the manufacture of multi-layer organic polymer composites are described, particularly applicable to composites including adjacent layers of a relatively water-soluble polymer (e.g. partially hydrolysed polyvinyl alcohol) and a relatively water-insoluble polymer (e.g. fully hydrolysed polyvinyl alcohol). The extruded layers are brought together within the die housing or by nipping means external to the die, or the relatively water-insoluble layer may be coated onto the relatively water-soluble layer. Specific designs of die are claimed, as are specific extrudable compositions and apparatus for conveying the same to the dies. The invention makes available for the first time a range of articles in which plastic parts are water-compatible in normal use but are completely degradable on contact with water during disposal, such as WC-disposable sanitary articles and water-degradable rigid containers for oil and petrol.

Abstract: An underwater soil excavation apparatus or a marine vehicle propulsion apparatus comprising a tube 11 in which a propeller 17 is mounted for rotation. A circumferential disc mounted variable geometry piston drive 21 is mounted to the tips of the propeller blades and protrudes into and is enclosed by a circular chamber 25 around the outer periphery of the tube. Water pumped into the circular chamber opens hinged vanes 26 that form pistons in the chamber and cause the propeller to rotate and thereby draw water through the tube from an inlet at one end to an outlet at the other. The apparatus is particularly useful for excavating holes and trenches in the seabed and uncovering buried structures in the seabed. When mounted on a submerged vehicle or stucture the apparatus can be used to propel or orientate the object. <IMAGE>

A decoder selecting device is responsive to a decoder select signal to select a decoder, thereby controlling voluntarily the timing of latch signal generation. Display signal input in the time division manner is latched in first and second latch circuits through the latch signal. Thereafter, the display signal is transferred to a signal electrode driving circuit 78 through a line memory to display an image on a matrix panel 82.
