Patent GB-2138652-A (GB)
Title: Distributed PABX
Inventor: MEEK THOMAS ROBERT
IPC: H04M1/733
Filed: 1983-04-23
Abstract: A distributed telephone exchange has a number of nodal stations (1,2,3, ..., 10) each serving a sub-area of the area served by the exchange. Associated with each nodal station there is a number of cordless sub- stations. Communication between cordless sub-stations and nodal stations uses radio (or possibly infra-red) links, where communication between nodal stations is via a coaxial (or optical fibre) cable which interconnects the nodal stations. The cordless stations and nodal stations use low-power transmitters, and the localizations of their signals is assisted by attenuation in buildings' walls, etc. The exchange uses TDM (or possibly TDM/FDM), and it has a control circuit (CON), which may be combined with one of the nodal stations. This control circuit allots time slots in the cycle to the various nodal stations, and if one nodal is overloaded, it allots time slots to it from other stations. There is also an interface to a public telephone system. <IMAGE>

Title: 6 beta -Halopenicillanic acid derivatives
Inventor: VON DAEHNE DR WELF
IPC: C07D499/00
Filed: 1983-07-20
Abstract: A method is disclosed of preparing in essentially pure form penicillanic acid derivatives of the formula I   <IMAGE> in which X stands for chlorine, bromine or iodine, pharmaceutically acceptable, non-toxic salts of the compounds of formula I, and pharmaceutically acceptable, easily hydrolysable esters thereof, including salts of such esters. The 6 beta -halopenicillanic acids of formula I are potent inhibitors of  beta - lactamases from a variety of gram- positive and gram-negative bacteria, making the 6 beta -halopenicillanic acids as well as their salts and easily hydrolysable esters valuable in human and veterinary medicine. The derivatives of formula I and the salts and esters thereof are prepared by separating by chromatography or fractional crystallisation 6 beta -halopenicillanic acid or salt or ester thereof from a mixture comprising the 6 beta -halo derivative and the corresponding 6 alpha -halo and/or 6,6-dihalo derivatives. The mixture may be prepared by epimerization of a 6 alpha -halo derivative or by selective reduction with a boranate of a 6,6-dihalo derivative.
Patent GB-2152823-A (GB)
Title: Dice game apparatus
Inventor: COSTER ORA
IPC: A63F9/04
Filed: 1984-01-13
Abstract: A flat carrier member 1 has seatings 3 each shaped so as to trap a respective dice, but to allow it to turn freely, this being facilitated by slight rounding of the edges and corners of the dice, each seating being formed with circular openings in opposite faces 3 of the carrier member through which portions of the dice project and are visible. When rubbed between the hands of a player, the dice can thus roll over quite freely. The thickness of the carrier member 1 is slightly less than that of the individual dice so that when placed on a flat surface, the dice are turned so that one face lies flat on the surface and the opposite face is clearly visible. As illustrated, the faces of the dice are marked with letters for the playing of a spelling game. <IMAGE>

Title: Optical transmitter distortion compensation circuit
Inventor: KAISER NORBERT
IPC: H04B10/50
Filed: 1984-11-16
Abstract: The circuit for compensating third-order distortion caused by a laser (3) in a signal to be transmitted contains a pre-equaliser (2) ahead of the laser (3) and an evaluating circuit (4) which senses the distortion in the signal at the output of the laser (3) and controls the pre-equaliser (2). A test signal generator (5) feeds a first out of band test signal (fo) into the pre-equaliser (2), and the third-order distortion of this signal at the output of the laser (3) is compared in the evaluating circuit (4) with a second test signal (3fo) having three times the frequency of the first test signal (fo). The comparison gives a manipulated variable (I) for the pre-equaliser (2). <IMAGE>

Patent GB-2166311-A (GB)
Title: Receiving apparatus
Inventor: DAWSON JOHN HOWARD
IPC: G01S7/285
Filed: 1985-10-23
Abstract: Received signals, for example in a radar system, are often divided at 6, Figure 1 (39 Figure 2) into I(0 DEG  phase shift) and Q (90 DEG phase shift) signals, or are split (at 65 Figure 5, 68 Figure 6) into in-phase signals (7,9 Figure 5 and 40, 41 Figure 6) and processed separately. However, the channels along which the two signals travel almost invariably have different characteristics, introducing errors. By homodyne mixing the I and Q signals or split in phase signals at 8 and 10 with a sequence of phase shifted signals from an oscillator 2 the I and Q or split in phase signals, or inversions of them, are switched between the two channels X and Y. After processing, they are recombined and since they have passed along both channels errors due to differences in the channels X and Y tend to be reduced. <IMAGE>

Title: An etch technique for metal mask definition
Inventor: BRAMBLEY DAVID ROBERT
IPC: G03F1/80
Filed: 1986-04-01
Abstract: A technique (figure 3), for high resolution feature mask definition, in which a selectively non-erodable masking layer (1) is defined using electron resist (7) and electron lithography, and used in the selective etching of a metal coating (3). Another selective etchant is used subsequently to remove the masking material (1). The metal coating (3) is typically of chrome and may be selectively etched using a chlorine/oxygen plasma. The masking material (1) may be silicon dioxide and etched using a hydrogen containing fluorocarbon (eg. CF4/H2; CHF3). Alternatively, it may be of aluminium and etched using a chlorine, boron trichloride or carbon tetrachloride plasma. Other masking materials may be used eg. titanium, silicon, germanium or nickel. The masking layer may be formed using electron resist above the layer material (figures 1 to 3). Alternatively, the masking material and electron resist may be applied in reverse order and a float-off process used (figure 6).
Patent GB-2193980-A (GB)
Title: Fabric
Inventor: MC KENTY CAROLINE ANNE
IPC: D04B1/20
Filed: 1986-06-13
Abstract: A precursor fabric of open construction, preferably a weft- knitted fabric, is formed from two or more yarns which exhibit different heat shrink characteristics. Heat treatment is effected to produce differential contraction of the yarns. The precursor may be made by knitting or weaving. By using thermoplastic yarns in combination with low shrink yarns such as those of natural fibres it is possible to produce structural fabrics having interesting and useful properties. The shrinkable yarns may form a ground fabric in combination with low shrink pile yarns. Alternatively as shown the shrinkable yarns may form localised bands of one or more courses. Stiff ribs may result which can be formed into three tubes or the like e.g. by sewing or glueing. The heat shrinking step may be performed while the fabric is under restraint or on a mould. Either type of yarn may be inlaid. The shrinkable yarn may be an elastomer. End uses include chair backs, supportive or decorative wear and impact-protective wear. <IMAGE>
