Title: Conductive strip heating element
Inventor: MCWILLIAMS JOSEPH ANTHONY
IPC: H05B3/74
Filed: 1994-06-24
Abstract: An electrical heating element for a radiant electric heater comprises an elongate electrically conductive strip (1) for partial embedding edgewise in a base of thermal and electrical insulation material (3), the strip being composed of an elongate continuous upper portion and an elongate discontinuous lower portion integral with the continuous portion, the discontinuous portion being intended for embedding in the base and being provided with a plurality of discontinuities therein comprising slots or slits (4) extending from that edge of the discontinuous portion of the strip which is to be embedded. The width of the slots or slits (4) and of material (40) of the discontinuous portion of the strip therebetween is selected to be sufficiently small such that during operation of the element in a heater, thermally induced mechanical stress in the strip is reduced to a level such as to inhibit crack formation in the strip. <IMAGE>

Title: Optical voice data transfer between recorders
Inventor: TERUI NOBUO
IPC: H04B10/114
Filed: 1995-04-13
Abstract: A portable unit 1 records voice data from microphone 3 in a SRAM, EEPROM, flash memory or similar 10. When the portable equipment is placed alongside desk-top equipment 2, permanent magnet 21 closes reed switch 25 whereupon desk unit 2 activates electromagnet 24 to close reed switch 20 in the portable equipment. The contents of memory 10 in the portable unit 1 are then converted into optical form, transmitted to the desktop unit 2 and stored there in memory 10 which may be a flash memory, magnetooptical disk, or magnetic disk or tape. A variant of the desk-top equipment (fig 7) uses a semiconductor memory (103) in the first instance, from which the data is transferred for analog storage on magnetic tape (130). A switch (107) enables the contents of either memory to be reproduced audibly (112).   <IMAGE>

Title: Separation and reovery of self-adhesive composite material
Inventor: GREINER RALPH
IPC: B03B5/28
Filed: 1996-02-27
Abstract: A method for the single-type recovery of plastic materials from starting pieces of a multiple composite material 1, 2, comprises  (a) comminuting the starting pieces into particles of a size compatible with the process; (b) cooling the shreds of composite material to temperatures below room temperature; (c) in a cold state, subjecting the pieces to a mechanical alternating bending stress and/or a shearing stress, to separate the films 3 from the prepreg pieces 1, 2; and (d) subjecting the mixture of film clippings and free prepreg pieces to a wet, density-selective, flotation-like float and sink separation, the films floating the free prepeg pieces sinking.  The process is used for the recovery of pieces of prepreg fabric from flexible cutting residues in which prepreg webs or similar self-adhesive webs are lined with films 3 on both sides. Comminuted composite pieces (18) are fed into a cooling region (4), the cooling being water optionally containing anti-freeze. The pieces are subjected to bending and shearing stress by rollers (9, 10) and are fed into a separation region (6). Gas is passed through a porous plate 12 and components (1, 2 and 3) accumulate bubbles; due to the different densities of the components the films (3) float to the surface and the pieces of fabric sink onto an air-permeable discharge belt (13).

Title: Inflatable flying canopy
Inventor: THOMPSON JOSEPH
IPC: B64D17/02
Filed: 1997-02-10
Abstract: An aerodynamic canopy is defined by upper and lower sheets (1)(figure 2) and 2, supported by a framework and joined together to define an aerofoil shape, when free-stream air is admitted via a mouth 12, to the space defined between the sheets to inflate the canopy.

Title: Preventing damage to a compression-ignition i.c. engine when a fuelling fault occurs by relieving the combustion chamber pressure to the intake side
Inventor: POLACH WILHELM
IPC: F02M25/07
Filed: 1998-09-08
Abstract: In the event of a fault in an electrically controlled injection valve 15 or the electric control unit 10 such that high pressure fuel is injected continuously, the pressure in the combustion chamber rises above the normal maximum pressure and a pressure relief valve 27 opens to allow the burning gas to escape from the combustion chamber directly by the shortest path to the intake side 2 of the engine 1 via a relief line 26. This reduces the amount of fresh atmospheric oxygen which can enter the engine on each further induction stroke and so reduces the risk of destructive combustion. If the control device 10 detects the resulting disruption in driving power, eg by engine speed fluctuations, the injectors 15 or the high pressure injection pump 18 may be closed down. Alternatively the EGR return valve 6 may be fully opened while the air throttle 8 is held closed thus starving the engine of oxygen. The EGR return path may be kept short to assist the continuing combustion of incorrectly injected fuel.

Abstract: A current sensing circuit 30, for use with a switching rectifier circuit D1,D2 in a power supply circuit for a load, includes an inductor 32 which is provided at a position in the circuit which sees an alternating or discontinuous current. When diode D2 is forward biased, the load current flows through inductor 32 which stores energy. When diode D2 is reverse biased, the energy stored in inductor 32 is dissipated in a rectifier and filter circuit R1,D3,C2,R2. The output 34 is applied to an amplifier and feedback circuit (not shown), used to control the output of the power supply circuit and to limit the current.
