Patent GB-2186871-A (GB)
IPC: C01B31/30
Filed: 1986-01-16
Abstract: Preparation of metal carbides, nitrides, borides, silicides and phosphides, also metal alloys and pure metals, by providing a precursor in which there are organic ligands bonded to the metal or metals, such precursor having the element X also bonded directly or indirectly to the metal or metals, the ligand-metal bonding being weaker than the X-metal bonding whereby on pyrolysis the product MaXb results in which M represents the metal or metals, X represents C, N, B, Si, P and a and b represent the atomic proportions of M and X. The subscript b may be zero if an alloy or pure metal is to be prepared. The product MaXb can be prepared by relatively low temperature pyrolysis and the precursor can be used as a solution or a low melting solid. This enables one to apply a surface coating or to shape the precursor into a fiber, rod or other shape and to pyrolyze the coating or shaped article. M is a transition, lanthanide or actinide metal or tin.

Title: Device for connecting elongate objects
Inventor: GADSDEN JOHN ARTHUR
IPC: F16L47/22
Filed: 1987-02-09
Abstract: A device for connecting objects such as rigid pipes that are used to convey fluids. The device comprises a rigid tube (38) and a heat-shrinkable skirt (41). Inside the skirts are located a bonding inserts (40) of thermosetting adhesive, which is attached to a barrier insert (42). The two pipes to be connected are inserted into either end of the tube such that each pipe fits snugly within a swaged-open end of the tube. The device is then heated causing the skirts (41) to recover and the bonding inserts (40) to melt and flow into the connection between the pipes and the tube. The barrier inserts (42) prevent the adhesive of the bonding insert from flowing away from the connection. <IMAGE>

Patent GB-2246910-A (GB)
Title: Antenna
Inventor: BRANSON SIDNEY JOHN
IPC: G01S5/14
Filed: 1991-04-29
Abstract: A quadrifilar radio frequency antenna intended primarily for receiving signals from an earth orbiting satellite for navigation has four helical wire elements (10A-10D) shaped and arranged so as to define a cylindrical envelope (12). The elements (10A-10D) are co-extensive in the axial direction of the envelope and are mounted at their opposite ends in two printed circuit boards (16, 17) lying in spaced apart planes perpendicular to the axis (14) with the end parts of the elements being soldered to conductor tracks on the boards (16, 17), the tracks constituting impedance elements between the helical elements (10A-10D) and between the helical elements and (10A-10D) and an axially located coaxial feeder (18). The conductor tracks are such that the effective length of one pair (10A, 10B) of helical elements and associated impedance elements is greater than that of the other pair (10C, 10D) and associated impedance elements. In this way, phase quadrature between the two pairs is obtained at the operating frequency without using differently shaped helical elements, and with little or no adjustment of the elements in the manufacturing process. <IMAGE>

Title: A recoil redirecting gun.
Inventor: DUCOLON JR FREDRIC DAN
IPC: F41A25/10
Filed: 1991-05-14
Abstract: A recoil-redirecting mechanism for a gun includes a recoil-absorbing spring (1), a fixed pulley (4) mounted on the frame (17), and a travelling pulley (8) mounted on a longitudinally reciprocating block (2) which is longitudinally slidable relative to the frame (17) substantially parallel to and independent from the gun barrel assembly (7, 27, 28). A cable (3) having a first end fixed relative to the frame (17) operably extends over and is reversed in direction by the travelling pulley (8), further extends over and is reversed in direction by the fixed pulley (4), and has a second end fixed to the gun barrel assembly (7, 27, 28). The spring (1) biases the gun barrel assembly (7, 27, 28) and reciprocating block (2) so that, when the gun is fired, the gun barrel assembly (7, 27, 28) recoils rearwardly exerting rearwardly-directed force on the spring (1) and the second end of the cable means (3). The cable means (3) in turn, exerts force on the pulleys (4, 8) to thereby cause the block (2) to slide forwardly and to exert forwardly-directed force on the spring (1). An alternative embodiment provides a fixed gun barrel assembly with blow-back bolt. <IMAGE>

Title: Skill-with-prizes machine
Inventor: CHADWICK NEVILLE DALE
IPC: A63F9/18
Filed: 1992-02-24
Abstract: In a skill-with-prizes machine, the questions available to pose to a player are a relatively small subset of a much larger number of questions in the machine's memory unit. The active subset of questions changes during the working life of the machine. A large proportion of the questions in the new active subset are common to the preceding subset with a relatively small number of new questions. The change in subset may occur as a result of a predetermined event, such as a given time, number of games or the value of prizes awarded.   In this manner the commercial viability of a machine is maintained, whilst still rewarding the skill and knowledge of a regular user.
Patent GB-2254743-A (GB)
Title: Vector logic precharge circuits
Inventor: YETTER JEFFRY D
IPC: G06F7/52
Filed: 1992-03-11
Abstract: A logic system uses mousetrap logic gates 100 which implement vector logic. In a vector logic system, any number of valid vector logic states and one invalid vector logic state is defined by the logic signals on a set of logic paths. An invalid logic state is defined as the case when all logic paths exhibit a low logic signal. A valid vector logic state can be defined in a variety of ways. As described a valid vector logic state is defined as the case when one and only one of said logic paths exhibits a high logic signal. Furthermore, mousetrap logic gates 100 which can be connected directly in series and/ or parallel to collectively perform logic functions, implement the foregoing logic scheme. Each mousetrap logic gate 100 has an arming mechanism 108, ladder logic 110, and a buffer 112. A precharge is supplied by the arming mechanism 108 to the buffer 112. Incoming logic is operated upon by the ladder logic 110 and used to trigger the precharged buffer 112. Each of the mousetrap gates 100 is self-timed so that no output exists until all necessary valid inputs are present. <IMAGE>

Patent GB-929796-A (GB)
IPC: H03K5/15
Abstract: 929,796. Multiplex pulse signalling; transistor multi-stable state circuits. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Feb. 3, 1961 [Feb. 10, 1960], No. 4727/60. Classes 40 (5) and 40 (6). [Also in Group XIX] In a distributer for a time division multiplex system, e.g. a pulse code modulation system, a plurality of transistors TR1 to TRn are connected in a ring circuit so that only one transistor at a time is conducting, the biasing being arranged through diode clamps D1 to Dn so that initially the base of the transistor TR1 is slightly more negative than the base of the remaining transistors in the ring circuit and TR1 is conducting and the remaining transistors cut off. As described, V 4 = - 6 volts, V 1 =V 2 = +24 volts, V 3 =0 and V 5 = - 0.3 volts. A normally non-conducting transistor TRs is caused to conduct by the application of negative-going control pulses Vs to its base thus causing TR 1 to be cut off. The collector potential of TR1 falls and the base potential of TR2 also falls until diode D2 is cut off and capacitor C1 discharges via resistor RB2. At the end of the control pulse TR3 is cut off and since transistor TR2 now has the most negative base potential it conducts and the remaining transistors in the ring are cut off, the discharge rate of C1 being arranged so that the base of TR2 remains sufficiently negative to maintain the transistor conducting until the next control pulse. At the next control pulse TRs conducts cutting off TR2 and the cycle is repeated. C1 continues to discharge until the base of TR2 is clamped to earth potential V 3  by the diode D2 again conducting. The output pulses appear in the intervals between the control pulses as positive-going pulses over leads T1 to Tn. Additional series base resistors RT1 to RTn sharpen the leading edge of the pulses. The potential fed from the collector of the transistor Tn to the base of transistor TR1 may be adjusted to compensate for the different base potential of TR1. To produce output pulses of the same length as the control pulses rather than equal to the interval between them positivegoing control pulses with the positive peaks at zero volts may be used.
