Patent GB-866464-A (GB)
Abstract: 866,464. Spark ignition devices. BENDIX CORPORATION. April 2, 1959 [April 21, 1958], No. 11265/59. Class 7(4). A spark ignition device comprises an elongated ceramic member 16 supporting a central electrode 21 and a protective metal shell 14 surrounding the ceramic member and radially spaced a short distance from the surface of the ceramic member at a zone adjacent the inner end of the device, and having an inwardly directed flange 26 underlying and abutting the inner end of the ceramic member, the flange being provided with at least one aperture communicating with the space between the ceramic insulator and the shell and an opening 52, 54 being formed through the wall of the shell at a location remote from the flange. As shown an electrically semi-conductive annular body 29 tightly embraces the lower end of the central electrode 21 and overlies flange 26. The semi-conductive body 29 is preferably bonded to the insulator in a manner described. The annular member 32 is of metal such as copper and the compression ring 33 is made of metal such as stainless steel. Members 32 and 33 are held in place by a layer of hard solder 36. The diaphragm 25 may be made of a heatresistant nickel iron alloy and has its outer flange 39 soldered or brazed to the metallized inner wall surface 40 of the insulator portion 20. A flange 41 is adapted to be received in a counterbore at the outer end of an opening in the side wall (not shown) of an engine housing. A key or lug 42 is adapted to be received in a device locating recess in the engine housing. The retaining nut 44 retains the device in the opening. The spark discharge device is so constructed and arranged as to provide access for gases within the engine housing to the outer surface of the leg 17 of ihe insulator 16 throughout the major portion of the length thereof inwardly of the spark gap thereby to prevent undue progressive build-up of temperature in the insulator. Further the lower end of the wall of shell portion 14 is circumferentially divided for a substantial length upwardly from the spark gap so as to allow engine gases also effectively to cool the lower end of the shell. Member 45 is integrally connected to the main body of the shell at shoulder 47 as by welding. The outer metal shell or housing is made for example of heat resistant nickel alloy. The device may be used in various types of engines such as jet or ram jet engines.

Title: Telephone apparatus
Inventor: DOCHERTY BRIAN GERARD
IPC: H04M17/02
Filed: 1988-04-13
Abstract: A microprocessor (4) responds to dialling pulses and to payment (or absence of payment) via a coin validation unit (9) to control a speech synthesiser (5) which produces spoken messages on a telephone line (6) and/or on a speaker (3) to prompt the user into making payment for use of a telephone. The apparatus may be arranged to automatically "cut-off" the telephone upon non-payment. The apparatus may be arranged to produce messages on the line which disrupt communication, but without automatically "cutting-off" at any time. Date relating to operation of the apparatus (e.g. charging rate) may be entered into the apparatus by the user. The microprocessor (4) causes the synthesiser (5) to produce spoken prompts for guiding the user as the user enters the data.

Title: Induction loop driving ampliflier
Inventor: PIETERS LEON ANDRE
IPC: H04R27/02
Filed: 1989-03-17
Abstract: An audio frequency amplifier particularly for an induction loop system (19) wherein the input to said amplifier, consisting of stages (17, 18), includes a variable cut-off low pass filter (13). This filter controls the bandwidth of the amplifier in response to the detection of conditions approaching overloading of the amplifier by high amplitude high frequency signal components in such a manner as to reduce the high frequency response of the amplifier during periods when said high amplitude high frequency signal components might otherwise overload the amplifier. The filter (13) is controlled by a signal derived from the output of the amplifier (18), and fed via overload sensor (21) and time constant (22). The arrangement avoids resultant distortion of the amplifier output signal and also avoids the generation of radio frequency interference signals in the induction loop (19) connected to the amplifier output. The amplifier may be a current-driving amplifier or a voltage-driving amplifier.

Patent GB-2232292-A (GB)
Title: Data transfer
Inventor: SNYDER JOHN HARVEY
IPC: G11B27/034
Filed: 1990-03-29
Abstract: A method for putting photograph, film or video information as still images, via a digital process, onto a magnetic mastertape that is used for pressing an optical video-disc, which avoids the individual editing of each still image to be done within the transfer process. The still images are captured digitally and either stored on magnetic cartridge as an interim measure before transfer, or fed direct into a solid state video-recorder that is used to put the still images down onto the mastertape in one block, synchronous to the playback speed of the optical video-disc player. In this way "n" different and individual still images put down onto the mastertape in one block, without "n" individual edits, would occupy the correct space on the magnetic mastertape, so as to represent "n" separate images and frames at normal playback speed on the optical video-disc.

Title: Image forming apparatus with a photoconductive element
Inventor: NAKASHIMA YOSHIHIRO
IPC: G03G15/02
Filed: 1991-07-19
Abstract: An image forming apparatus for uniformly charging the surface of a photoconductive element (4) heated by heater (13) exposing the charged surface of the photoconductive element imagewise to electrostatically form a latent image via optics (3), sensing the charge on an exposed area by sensor (20), and developing the latent image by a toner at station (7). A linear equation is produced (see Fig 6) which is a reference representative of the input-output characteristic of a sensor responsive to the surface potential of the photoconductive element. The linear equation is used to calculate an accurate surface potential matching the output of the sensor irrespective of the distance of the sensor from the photoconductor. A bias voltage for development of similar image forming condition is controlled on the basis of the calculated surface potential. <IMAGE>

Title: I.C. engine fuel supply system
Inventor: CASARI JOHN
IPC: F02M37/08
Filed: 1991-08-23
Abstract: The system comprises a fuel tank 1, a reservoir 8 for fuel, a fuel pump 9, a change-over valve 11 to which the tank, the reservoir and the pump are connected, fuel metering equipment 2, a feed duct 4 for feeding of fuel from the pump to the metering equipment, a return duct 5 or a throttled branch duct from the pump outlet for filling of the reservoir, and a unit 6 for controlling the pump, the motoring equipment and the change-over valve. The control unit 6 is arranged to switch the changeover valve 11 when the engine 3 is cold so that fuel is pumped by the pump 9 out of the reservoir 8 into the feed duct 4 and to switch the valve when the engine is warm so that the pump conveys fuel out of the tank 1 into the feed duct. The use of the reservoir 8 when the engine is cold ensures that the same fuel is used for starting as was used when the engine was last operating in the warm state. This ensures that the equipment 2 is set for the fuel in use at starting regardless of refilling of the tank 1. <IMAGE>
