Patent GB-2267413-A (GB)
Title: Ring detect propagator
Inventor: MCFARQUHAR LORD HARRY
IPC: H04M19/04
Filed: 1992-05-30
Abstract: A ring detect propagator P will detect ringing signals in a telephone line or extension line L1 it is connected to or attached to. Upon ring detect the propagator will prepare to transmit its identity code via a medium such as radio waves or infra-red light. Transmission will occur when the propagator cannot detect transmissions from other propagators. Other propagators within range will receive the transmitted identity code, as will purpose-built receiver pagers. A pager will emit an audible or visual signal if a received code corresponds to its own identity code. A propagator will also transmit other propagator codes it has previously recorded. Transmissions will also be initiated when ring has not been detected but when the propagator has recorded other propagator identity codes. A propagator will not record identity codes which are already recorded within it, nor will it record identity codes which it has recently transmitted. <IMAGE>

Title: Container-closure assembly including a screw-cap having anti-backoff teeth
Inventor: SHAY JOSEPH J
IPC: B65D55/12
Filed: 1992-09-28
Abstract: A container-closure assembly comprises a container moulded of relatively soft plastic and a closure cap (10) moulded of relatively hard plastic and having a top wall (16) and a continuous side wall (14). Threads are formed on both the finish of the container and inward on the side wall of the cap. The threads of the cap comprise three threaded segments (22) spaced about the inner circumference of the side wall. The segments include an inward upwardly sloping rib, the upper surface of which is formed with a plurality of wedge-shaped teeth (26). In use, the closure is screwed on to the top of the container finish and the teeth dig onto the underside of the threads on the finish causing the instantaneous elastic deformation of the plastic of the finish to anchor the cap against removal. <IMAGE>

Title: Converter for a switched reluctance motor drive
Inventor: DAVIS REX MOUNTFORD
IPC: H02P25/08
Filed: 1993-01-13
Abstract: A thyristor bridge inverter 10 is connected to a switched reluctance (SR) convertor 51 - 56, 61 - 66 and to an ac source of voltage 11, without requiring a transformer, so that no circulating currents between a diode bridge rectifier 2 and the inverter 10 are possible.

Title: Fluorescent lamp starting and operating circuit
Inventor: KELLY JAMES GLENTON
IPC: H05B41/295
Filed: 1993-06-19
Abstract: A resonant start circuit for a discharge lamp includes a resonant combination of capacitance 7 and inductance and is used with an inverter 1, the frequency of operation of which may be varied. Initially at a value at which heater current passes through cathodes 17, 18 of the lamp, the frequency is swept to a value at which the resonant circuit resonates to provide a high voltage to start the lamp 3. In this invention the resonant circuit resonates at an harmonic, preferably the third harmonic, of the frequency of the inverter. In the preferred circuit the lamp cathodes are preheated at 100 to 140 kHz, as the frequency is swept down to 80 kHz the circuit resonates at 240 kHz and the lamp is subsequently run at 50 kHz. A practical circuit has a leakage reactance transformer 13, 14, 15, 16a, 16b connected to provide the cathode heating current and contributing to the inductance of the resonant circuit. The transformer has primary windings 13, 14, 15 which are well coupled to one another, but are not well coupled to the secondary windings 16. <IMAGE>

Title: Digital radio mobile frequency supervision
Inventor: LINDELL KARL BO
IPC: H04B17/00
Filed: 1993-09-08
Abstract: The frequency stability of the signals transmitted by a plurality of mobile stations (M1 - M10) to an associated base station (B1 - B10) within a radio network is supervised by first generating a reference signal (112) at the base station. The signals received from the mobile stations are compared to the reference signal (112) and a difference signal is generated. The difference signal is compared to first and second error values and if the difference exceeds the first error value, the mobile is summoned for a service adjustment. If the difference exceeds the second error value, the mobile is disabled from further transmissions. <IMAGE>

Abstract: 932,112. Labels. MAICO ELECTRONICS Inc. Nov. 25, 1959 [Dec. 12, 1958], No. 40087/59. Class 73. [Also in Group XXX] In apparatus for magnetically identifying a succession of material units (see Group XXX) the identification characteristics comprise magnetisable areas or tabs 22 arranged vertically and horizontally and each polarised with a predetermined orientation of magnetic polarity to provide a code.

Patent GB-2278463-A (GB)
Title: Central heating control system
Inventor: MCNAIR HENRY PETRIE
IPC: G05D23/19
Filed: 1994-05-23
Abstract: A boiler control system includes a room temperature sensor 10 which utilises radio transmission to send temperature information via antenna 11 to receiver 15 via antenna 16. The receiver will provide an output to a control unit 18 to cause actuation of the boiler 19 for example if the room temperature falls below a preset value. The temperature selected can be varied by means of up/down keys 13/14 on the sensor 10. Temperature information can be displayed by means of display 12. Unique coding identifies the transmitting sensor and transmission can be sequenced on a number of frequencies to reduce the risk of reception failure. Additional temperature sensors including a hand held unit each with a unique identity code can be used and transmission time is varied to avoid coincident transmission from the sensors. Telephone linkage for a number of devices can be provided. <IMAGE>

Title: Inert and energetic prepolymers co-cured with isocyanate
Inventor: HONEY PETER JAMES
IPC: C08G18/50
Filed: 1994-12-22
Abstract: Two or more isocyanate-curable pre-polymers having chemically different character can be cured together to provide an elastomer having advantageous physical and mechanical properties. In particular an appropriate combination of a chemically relatively inert prepolymer such as a hydroxy-terminated polybutadiene, polyether or polyester with a more energetic material of these classes but containing nitro-, nitrato-, azido- or sulphur pentafluoride substituents, can be used to produce co-cured elastomers having desired properties of burn rate, specific impulse, total calorific value etc. which make them suitable for use as binders for propellants, explosives and pyrotechnics. The conventional use of otherwise unsatisfactory additives for altering elastomer properties can thereby be avoided.

Title: Cable sealing and locking device
Inventor: FOSS RAYMOND CHARLES
IPC: H02G15/013
Filed: 1995-03-01
Abstract: A cable locking and sealing device comprises an elongate body of elastomeric material formed with at least one through-passage for receiving a cable and at least one longitudinal slit 17 extending down at least a portion of its length. The interior of the through-passage is formed with a series of annular ribs 19 which each taper in depth towards a point adjacent the longitudinal slit 17. When the device is pulled into an entry port, its elongate body becomes radially compressed thereby holding the cable firmly in place: however, the sealing effect of the ribs 19 against the cable is not compromised by any relative longitudinal displacement of the portions of the body either side of the slit 17. The device has external annular projections either side of an entry port to prevent axial movement of the device.

Filed: 1996-01-19
Abstract: A brake system with ABS and ASR includes return pumps 25, 25', induction valves ASV, change-over valves USV, and inlet and outlet valves EV, AV. The return pumps and/or the change-over valves and/or the induction valves can be controlled automatically in dependence on a signal representative of brake pedal 40 actuation and resulting from pedal or master cylinder piston travel, master cylinder pressure, or rate of change of master cylinder pressure. The system will increase wheel brake pressure on brake fade and "panic" braking being sensed.
