Title: Friction element such as a brake pad
IPC: F16D55/22
Filed: 1981-02-11
Abstract: The element is adapted to frictionally engage a movable tack e.g. a baking surface on a disc, ring, drum or band and comprises a support (13) to which is secured a friction lining (14), the support being formed with a gradually varying thickness (e.g. at e and E) so that the distribution R of the pressures P over the application face (18) of the lining conforms to a pre-selected distribution, for example and as shown a uniform distribution. The ability to vary the distribution of pressures over the application face enables the wear pattern of the lining to be controlled. A number of embodiments are disclosed, e.g. in Figs. 1-4 thickness of support (13) is lower at e where support is acted on by a piston (15). Variation in thickness of support may be formed by provision of ribs produced by corrugations. The ribs may have reinforcements. Patterns of ribs are disclosed. Details of composition of the support and lining are given- and production of the element by moulding. <IMAGE>

Title: Galvanic cell
IPC: H01M6/16
Filed: 1981-08-18
Abstract: The invention provides a galvanic cell comprising a negative lithium electrode, a non-aqueous electrolyte and a reducible positive electrode, wherein the electrolyte is a solution of a conducting salt in a mixture of diglycol dimethyl ether and ethylene sulphite. Preferably a 1 molar solution of one of the salts LiPF6, LiClO4 and LiAsF6 in a mixture of diglycol dimethyl ether and ethylene sulphite is used as the electrolyte. The high boiling points of the solvent components (160 DEG C and 173 DEG C) ensure, on account of the low vapour pressure, that the cell is safe to handle. The electrolyte conductivity is almost 10<2> OMEGA <-1>.cm<-1>. The stability of the electrolyte with respect to the electrode materials is manifested in the good storability of the cell. CrOx, Bi2O3, Pb3O4 and MnO2 are suitable as positive electrode materials.

Title: Laminated panel and method of making such a panel
Inventor: ADAMS RONALD W
IPC: B60R13/02
Filed: 1982-08-27
Abstract: A cushioned decorative panel comprises a non-woven substrate 10 having a surface layer composed of thermoplastic fibres, e.g. polypropylene, a decorative surface fabric sheet 12, and a piece of foam 14 between the sheets 10 and 12. The panel is formed in a mould 18 having male and female halves 22 and 16 defining a mould cavity.

Title: Automatic transmission control
Inventor: YOUNG ALASTAIR JOHN
IPC: F16H61/02
Filed: 1983-03-24
Abstract: Electro-hydraulic control system for an automatic power transmission providing forward ratios, neutral and reverse gear ratio in which forward ratio changes are effected under power by releasing one clutch (12 or 13) interconnecting the transmission input and output through one engaged gearset simultaneously with engaging another clutch (13 or 12 respectively) interconnecting the input and output through another engaged gearset. The control system comprises five hydraulic gear actuators (GA1, GA2, GA3, GA4, GAR) each for engaging and disengaging a separate gearset and three electro-hydraulic valves (A,B,C) for controlling the supply of hydraulic fluid from a pump (PP) to the hydraulic gear actuators in response to ratio selection signals derived in an electronic control system (EC). A manually operable mode selector valve (MV) is arranged to supply the electrohydraulic valves with fluid under pressure from pump (PP) when a driving mode is selected thereby but to cut off fluid pressure supply from the electro-hydraulic valves when a non-driving mode such as neutral is selected. Reverse gear actuator (GAR) and first gear actuator (GA1) are selected by the same ratio selection signals (A = 0, B=1,C=1,) and pressure is distributed to the appropriate one of these gear selectors through the mode selector valve in dependence on whether a forward driving mode or reverse is selected thereby.

Title: Apparatus for transmitting electromagnetic energy
Inventor: MIGDAL RICHARD
IPC: H03L7/07
Filed: 1983-07-11
Abstract: Plural R.F. transmitters 2A, ... e.g. for heating a nuclear fusion torus, are phase-locked as slaves to one 2A that is set up as the master by means of switches 4, 5. Each transmitter has a main voltage- controlled oscillator 8 and a second voltage-controlled oscillator 24. From master 2A the output of the oscillator 24 is passed along a line 19A to a central combiner/splitter 20 from which it is passed along lines 21A, 21B, 21C and 21D of equal length to all transmitters. The signal returned on line 21A to the master 2A phase-compared at 23 with the oscillator 8 output to control the V.C.O. 24 so as to make its phase, after returning from the central distribution point 20, the same as that of the oscillator 8. In slaves 2B, 2C, 2D the output of the phase sensitive detector 23 after adjustment at 25 is used to control the frequency of the slave V.C.O. 8 momentarily to phase-lock it to that of the master 2A. The frequency of the master V.C.O. 8 is tuned to minimise back reflection from radiating element 1A by means of an A.F. oscillator 14 which modulates the frequency of the oscillator 8; and means 9 and 12 for measuring the reflection co- efficient from the radiating element 1A. The variations in reflection coefficient are phase-compared 16 with the A.F. oscillator output to control the frequency of the oscillator 8. <IMAGE>
