Title: Muscle stimulation appts. using electrodes on skin - circuit enables duration of pulse trains to be controlled
IPC: A61N1/36
Filed: 1973-09-12
Abstract: A device to stimulate the muscles by applying pulses through electrodes placed on the skin is designed to enable the user to control the duration of the pulse trains as well as the amplitude. A clocking device (2) supplies square wave pulses to a frequency divider (3) which feeds two frequencies (B, C) to a bistable oscillator (5) from which is obtained a rectangular pulse (D) at short duration proportional to C and spaced by a time double that of B. By means of contactors (7, 8) for the signals B & C, the duration and spacking of the pulses applies to the skin can be controlled. Part of the output of the divider (3) is fed as a signal E to a three stage frequency divider (9a, 9b, 9c) and a further oscillator (16) in an arrangement with a further contactor (14) by means of which the ratio between the pulse trains and their intervals can be changeD.

Title: Fuel economiser for IC engine - has system injecting water vapour in air-fuel mixture
IPC: F02M25/06
Filed: 1973-12-24
Abstract: The equipment consists of components to add water vapour to the air/fuel mixture in the air intake of an internal combustion engine. The vapour will break down into oxygen and hydrogen at the combustion temperature, thus releasing oxygen for more complete combustion. The water vapour is supplied in the mixture intake duct of the carburettor. The amount of vapour supplied depends on the throttle valve opening. The water is heated electrically and supplied as a vapour. An atomiser (6) ensures adequate mixing in the duct. An alternative detail is to supply the water through a float chamber and diffuser as in a conventional carburettor.

Title: Incombustible cable trough - is moulded from a sand and cement mixture with reinforcement
IPC: H02G3/04
Filed: 1974-02-07
Abstract: This cable trough is moulded from a mixture of cement, silicious sand of 0.8mm granular size, plastifying agent and water. One form of mould can have a flat bottom with hinged sides. The top of the cable trough can have returned or rebated edges and therefore the internal parts of the mould need to be made from multiple pieces (9, 11, 13, 14). Cut-outs and cable holes can be incorporated into the mould. The moulding can be reinforced by metal rods or glass-fibre etc. This provides a cable trough that is incombustible with good tensile and compression characteristics.

Title: Tape feed control system - with sensing of tape between a store and user apparatus to control feed
IPC: D05B35/06
Filed: 1974-05-14
Abstract: Tape is withdrawn from a source and fed via a guide to a user apparatus. A movable device senses the amount of tape between the source and the guide and, by its position, controls the rate of withdrawal of the tape from the source. Process is applicable to supplying tape from a reel to a sewing machine. When using elastic tape it is difficult to control feed to a sewing machine at constant tension. New feed system supplies tape at constant tension.

Title: Measurement of heat used in central heating system - uses two thermocouple junctions powering voltmeter eliminating power supplies
Inventor: LEGER PIERRE
IPC: G01K17/18
Filed: 1974-12-19
Abstract: Measurement of heat used in a hot water central heating system employs a thermocouple with one junction attached to the inlet and one junction attached to the outlet. The junctions power a voltmeter giving temperature difference thus eliminating the need for mains or battery power supplies. One thermocouple junction (4) is attached to the hot water pipe (1) of a central heating system and a second junction (5) is attached to the return flow pipe (2). The junctions are connected to a voltmeter (10) measuring temperature difference. Water flow is measured by a flowmeter (D) driving a cam (11) with a spar (12) which causes a second cam (14) with steps (15) to but against the voltmeter pointer (19). During descent the second cam operates a ratchet (21) on a counter (22) giving heat used.

Title: Air supply measuring device for I.C. engine - computes air speed from phase difference of ultrasonic wave at two detectors
IPC: F02D41/18
Filed: 1975-01-28
Abstract: The measurement of air flow in the inlet pipes of internal combustion engines ensures that correct operation nd correct air to fuel ratios are being achieved. An ultrasonic generator (14) is mounted symmetrically with respect to two ultrasonic receivers (16, 18) on an air inlet pipe (10) attached to the filter (12) on an engine. The generator is powered from a high frequency oscillator (20) which is modulated (22) by a lower frequency. Two filters or discriminators (24, 26) separate the carrier from the modulating signals for phase difference calculations (28) for the received signals. The modulating signal is identically processed (30) and the signals are then mixed (32) to obtain air speed from which mass flow is obtained. A control circuit (36) provides mixture and timing control signals for the fuel injectors.

Title: Lead acid accumulator separator - made of microporous resin coated plastic mat with conical dimple impressions
IPC: H01M50/491
Filed: 1975-10-21
Abstract: The separators for a lead-acid accumulator are made of thin carrier layer with large pores to which a solution of a resin, a solvent and a fluid miscible with the solvent has been applied and dried. Dimples are impressed into this foil to contact the positive plates with their points and the negative plates with their flate parts and to act as spacers, filled with electrolyte. This results in separators of high mechanical strength by a partial closure of the micropores. The remaining pores act as filters for heavy metal poisons so that the battery life is lengthened. The separators ensure a high capacity for the accumulator.
