Title: Ceramic welding process and powder mixture for use in same
Inventor: ZVOSEC CHARLES MICHAEL
IPC: C04B35/04
Filed: 1990-07-17
Abstract: In ceramic welding processes, oxidising gas and a mixture of refractory and fuel powders are projected against a surface and the fuel is burnt to generate sufficient heat that the refractory powder becomes at least partially melted or softened and a cohesive refractory mass is progressively built up against that surface. In order to reduce any tendency for the weld mass to include a low-grade refractory phase and thus promote the refractoriness of that weld mass, the fuel powder is present in a proportion of not more than 15% by weight of the total mixture and comprises at least two metals selected from aluminium, magnesium, chromium and zirconium, at least the major part by weight of the refractory powder consists of one or more of magnesia, aluminia and chromic oxide, and the molar proportions of silica and calcium oxide present in the refractory powder (if any) satisfy the following expression:      {SiO2} % </= 0.2 + {CaO} %. The elements of the fuel may be present in the form of an alloy.

Title: Facsimile systems
Inventor: TAKAHASI CHUSEI
IPC: H04N1/00
Filed: 1991-01-30
Abstract: A mobile facsimile telecommunications system utilizes an automobile telephone system as a transmission path.

Patent GB-913404-A (GB)
Abstract: 913,404. Spring upholstery. GREAVES & THOMAS Ltd., and COBB, W. R. July 31, 1961, No. 27706/61. Class 52 (4). Sinuous springs 14 are attached to the frame 10 of a chair by means of a clip 17 which at one end has a tongue 25 which engages the frame along the indent 23 and at the opposite end has a rounded portion 29 which engages the spring. The top surface 18 and face 24 of the indent 23 enclose an acute angle X around which the tongue 25 engages and the hook part 26 rests in an indent 22 on the opposite side to the indent 23 and raises the clip 17 slightly so that the centre of the end portion 27 of the spring is in line with the top surface 18 and the apex of the angle X. In a modification (shown in dotted lines), the indent 23 is replaced by a slot. In another modification the indent 22 is removed, the hook part 26 shortened and the surface 18 inclined slightly away from the angle X so that the tension of the spring still acts through the apex of angle X. In yet a further modification the frame member may be rotated through a right angle and the clip engaging similar indents on the outside surface of the frame. The end 28 of the spring is offset to prevent easy withdrawal and the rounded portion 29 is swaged or flared at 30 to avoid fretting between the clip and spring. The indents instead of being continuous may be separate for each clip.

Title: Hexagon-socket keeper for horseshoes
Inventor: CARDRICK ARTHUR WILLIAM
IPC: A01L11/00
Filed: 1992-02-22
Abstract: A hexagon-socket keeper screw for protecting threaded stud-holes in horseshoes has the mouth of the socket expanded to produce an almost circular entry which tapers into the hexagon socket at a depth of about two thread pitches. The expansion of the upper thread pitches is chosen so that the keeper can be tightened into a standard tapped hole leaving up to about one thread pitch exposed. The high grade alloy steel from which the keeper is made is used in a hardened state without the standard temper to improve toughness.

Title: Heat transfer between fuel and air in supersonic jet engine
Inventor: GRIEB HUBERT
IPC: F02C7/18
Filed: 1992-09-24
Abstract: A device for cooling intake air of a supersonic jet engine 1,for subsequent use as a cooling fluid, comprises a heat exchanger 12 in which the temperature of the air (supplied by line 11) is reduced by means of heat transfer between the air and a cryogenic fuel (supplied by line 15) to be burnt in the engine 1. In order to keep the operating temperatures of the heat exchanger within manageable limits, a partial stream T, of the fuel is recirculated and a partial stream L of the air is deflected downstream of the heat exchanger 12 and is mixed with air upstream of the heat exchanger 12 to reduce the temperature. Blowers 21, 23 assist return flow of vaporised fuel and air respectively. Details of two alternative heat exchanger constructions are given (figures 2 to 6) both providing for the blower-assisted return flow of air. <IMAGE>

Title: Condition monitoring systems
Inventor: SMITH JAMES DEREK
IPC: G01M13/02
Filed: 1992-10-22
Abstract: The presence of high frequency vibration pulses is used to monitor conditions at surfaces of components in rolling and/or sliding contact, e.g. a pair of gear wheels 33, 34. Signals output by accelerometers 31, 32 are merged and high frequency components, e.g. in the range 20kHz to 200kHz, are enhanced by a signal enhancer 38 and processed by a signal processor 39 to detect vibration pulses emitted due to contact at the interface. A warning signal is output by a go/no go indicator 40 if processed parameters exceed acceptable limits. The system may be used to detect direct surface contact due to failure of oil supply or indirect contact arising from the presence of debris particles in the oil. <IMAGE>

Title: Timepiece with synchronising means
Inventor: OGIYAMA MORIYASU
IPC: G04G5/00
Filed: 1992-11-19
Abstract: A timepiece is provided which can economize power consumption by executing a time data receiving operation from a radio signal only when necessary. The time data reception operation starts in response to a signal generated when power (e.g. battery) is turned on. When a time data is correctly detected at 3, the current time is adjusted at 5, and the correction time error is stored at 6. When the correcting time error is 5 sec or more, the next time data is received at a predetermined adjustment time determined at 10. If the correction time error data is less than 5 sec no reception operation is executed, and a new data obtained by adding one sec to the stored correction time error data is stored as a new correction time error data thus allowing a longer time period to elapse before the next comparison is made. <IMAGE>

Patent GB-2273353-A (GB)
Title: Security device
Inventor: HENLEY COLIN STEPHEN
IPC: G07D7/12
Filed: 1993-11-29
Abstract: The device for detecting security strips in thin transparent or translucent sheets comprises an enclosed scanning chamber (1) adapted to allow the passage of a bank note or similar security (12). The note passes between one or more rows of infra-red radiation sources (10) and matching rows of associated infra-red radiation detectors (11) spaced from the radiation sources within the scanning chamber. The output signal from each detector depends upon the presence or absence of an infra-red opaque object. Logic means is arranged to receive the output signals from each row of detectors and provides a strip detection signal if half or more of the signals in a row are substantially reduced. The strip detection signal initiates an output signal such as an audible warning and/or illumination of an indicator light. The logic output from each row may be fed to a latching circuit with a limited latch duration. Simultaneous latching of the latching circuits is detected and used to operate the output signal and to reset the latch circuits. The device is responsive to the width of the security strip. <IMAGE>
