Title: Hot press mounting of ceramic tiles on to thermoplastic film - using facial support leaving reverse exposed for installation
IPC: E04F13/08
Filed: 1974-12-06
Abstract: Panels comprising groups of ceramic tiles mounted side by side on a support film with sufficient inter tile spacing for accepting grouting etc., where the tiles are mounted by hot pressing the external faces against a thermoplastic film which forms an interfacial seal against the tile and/or glaze thereon. Leaving the rear faces of the tiles exposed makes subsequent installation on to a wall or floor surface relatively easy. The face film may be stripped off afterwards or retained as a protective (transparent) cover.

Title: Control circuit for semiconductor switching device - makes use of two opposed current generators and includes two differential amplifiers
Inventor: BOURREAU GEORGES ROGER
IPC: H03K17/74
Filed: 1974-12-18
Abstract: The control circuit for semiconductor switching means (3) using at least one diode (31) in parallel with a resistor (32) employs two current generators (G1, G2) providing currents of equal value but of opposite sense, and two associated differential amplifiers. The latter are each provided by two similar transistors (11, 12, 21, 22) the emitter-collector circuits of which form two branches, respectively connected to the two terminals of the switching means (3). The bases of the two transistors which are connected to the same terminal of the switching means (3), simultaneously receive a voltage pulse from a control input, such that the ratio of the currents provided by each differential amplifier is altered.

Title: Composite rubber-bonded panels - of thermoplastic foam and corrugated card for lightweight, stiff heat resistant vehicle head linings etc.
Inventor: ROTH JACQUES
IPC: B60R13/02
Filed: 1975-02-05
Abstract: Shaped composite panels made by bonding together a layer of corrugated cardboard, a pre-fabricated sheet of (thermoplastic) foam and a superficial covering material, the bonding agent being coatings of solns. of a rubber based adhesive. The opposite face of the cardboard layer is normally also partially or completely covered with adhesive bonded foam, and the laminated layers are then hot pressed to obtain the required shape and cure the adhesive. Used for mfr. of decorative panels, display panels, vehicle roof linings. The composite panel has a higher stiffness/wt. ratio, esp. if heated, than thermoformed unreinforced plastic sheet, and is not as susceptive to local physical damage as structures relying on the corrugated profile of cardboard.

Inventor: LEVY IRA S
IPC: C22F1/18
Filed: 1975-04-15
Abstract: An alloy comprising >=95% Zr and at least one of Cr, Sn Nb, Fe, Ta, Ni and Al which is thoroughly annealed is treated by subjecting the alloy to a tensile creep strain of 3-10% while holding in a temp. range at which creep will occur yet which is below the temp. for significant recovery by loading at a strain rate of 0.001-0.01 inch/inch/minute until the tensile creep strain is obtd. and holding at the final load for at least 15 mins.

Title: To variable speed hydraulic motor - has slide valve to contro number of cylinders connected to fluid circuit
IPC: F03C1/40
Filed: 1975-07-16
Abstract: The hydraulic motor has a rotor with a number of radial cylinders housing pistons actuated by rollers running against the inner surface of the cam ring. Hydraulic fluid is supplied through the central block by means of the holes and the ports to the orifices. As the rotor rotates the orifices are connected alternately to the inlet and the outlet. The slide valve which is operated hydraulically or by any other suitable means controls the number of cylinders which are connected to the pressure supply passage and the return passage, thus changing the motor speed although the volumetric flow of the hydraulic fluid remains constant.

Title: Connection between external aerial receiver - using capacitor coupling and glass dielectric
IPC: H01Q1/32
Filed: 1975-08-12
Abstract: This form of aerial connector is particularly applicable to car radios, and avoids the need to cut holes in the car bodywork to permit enetry of the aerial cable. A coupling capacitor is formed by fixing two metal foils (1, 2) on either side of a window (6), typically the windscreen. The foils are opposite each other, and the inner one (1) is connected to the receiving equipment (7), whilst the outer (2) is electrically connected to an aerial (4) held in a suitable support bracket (3). In most cases it is beneficial to pass the signal through a low noise amplifier with a high input impedance before applying it to the receiver.

Title: Glass wall or window surveillance system - has ultra sonic transmitter and receiver placed in opposite corners of glass window
Inventor: LAKESTANI FEREYDOUN
IPC: G08B13/04
Filed: 1975-11-14
Abstract: On the glass wall, window or partition are placed at opposite corners an ultra sonic generator transducer (2) and an ultra sonic receiving transducer (5). The ultra-sonic generator (5) is excited by an electrical oscillator (3) to which is connected a conductor (4). The receiver (5) is connected to the input of an amplifier (7) by a conductor (6). The output of the amplifier (7) is connected by a conductor (8) to a peak detector (9) which is connected to a shafting circuit (11) whose output (12) is fed to an alarm device. The ultra sonic waves that the generator (2) applies to the glass (1) is propagated in it and these waves reach the detector (5). This detector (5) transmits a corresponding signal which is amplified and then passed to the detector demodulator (9) which gives a constant level in the absence of perturbations. When perturbations are present the demodulatior gives out a variable signal which stabilises itself when the disturbance disappears.

Title: Detection of interface between hard and soft water - to initiate regeneration of ion exchange resin in water softeners (BE180676)
Inventor: JOHN CLAUS
IPC: B01J47/14
Filed: 1975-12-19
Abstract: In a method for establishing the interface between two differently conditioned liqs., esp. water, using electrical conductivity measurements, the electrical resistance of the liq. is determined by a bridge circuit in each of two equal lengths of a flow path of the liq. which lie one after the other. The bridge circuits generate an electrical signal as a result of a difference in the resistance they measure and the signal is fed to an indication, or control element. The detector is unaffected by the comparatively slow variations in dissolved chlorine, oxygen, sodium sulphate etc. occasioned by outside influences. Max. utilisation of exchange resin and min. consumption of regenerating soln. is achieved. Reduced content of dissolved salts is achieved.

Title: Emergency release for vehicle safety belt - uses shock to exert pull on spring loaded dashpot to release ball bearing sleeve after time delay
IPC: B60R22/32
Filed: 1976-09-29
Abstract: The emergency release is fitted to a vehicle safety belt and disengages this automatically after a shock. It comprises a cylinder (1) fixed to the bodywork (22) and cast containing a spring loaded piston (2, 5). The assembly forms an oil filled dashpot (3, 14), its rod (6) attached to the belt (16) fixing by means of a sleeve (13). Ball bearings (8, 14) in grooves (7, 15) hold this and another sleeve (11) together as a joint, spring biased (12) to prevent dislodgement of the balls. A shock pulls the dashpot piston along the cylinder, the spring returning this after a delay. This movement dislodges the balls in their sleeves, releading these and the belt.
