Title: Battery cell base cup coated with high oxidn potential metal - to prevent leakage of electrolyte during long storage
IPC: H01M6/08
Filed: 1973-11-28
Abstract: A battery cell is claimed having a positive electrode, an electrolyte a negative electrode container and a small cup, at least the surface of which is made of an electrically conducting matl. surrounding the base of the container. A plastic sheath covers the lateral wall of the container and is turned back over the periphery of the cup while a waterproof seal prevents loss of electrolyte between the cup and the sheat. The conducting matl. is stainless at normal redn. potentials of the prod. discharged at the positive electrode since its normal oxidn. potential is higher than the said redn. potential. Specifically the positive electrode is MnO2-based and the conductor is Cu, Ag or Au or a varnish based on C.

Title: Laser beam electrical current transmission system - has light amplifier transmitter generating concentrated coherent high flux light beams towards two receiver reflectors
IPC: H01T23/00
Filed: 1974-11-14
Abstract: Laser electrical transmission system uses as its current path the air ionised by the laser radiation and it uses a light amplifying transmitter tube. Transmission is stimulated by radiations generating concentrated beams of coherent light, of high flux towards two reflector conductors connected to a receiver. The system uses two transmission tubes (1, 2) which direct ultraviolet light onto two laser beams (5, 6) ionise the ambient air along their radiation path. At the end of the laser tubes are placed lenses (7, 8) which neither absorb nor reflect the radiation, but which are conducting.

Title: Self-controlled single-phase thyristor inverter - operates in parallel with several inverters and uses preset frequencies for inverter control
Inventor: CHAPRONT PIERRE
IPC: H02M7/48
Filed: 1974-12-26
Abstract: The thyristors are controlled by control elements determining the operating frequency and the current flow cut-off angle. When one invertor current (i) lag increases, or lead decreases with respect to the output voltage (u) of other invertors, this invertor frequency is increased, and when the current lead is increasing or lag decreasing, its frequency is reduced in accordance with a specified formula. Preset frequencies for the individual inverters so affect the respective control elements (42) as to provide the frequency dependent control. Preferably voltages (uo) are also preset for the individual inverters for changing the current flow cut-off angle of the thyristors.

Title: Seal between two chambers between which materials pass - through connector duct, is effected by injecting pressure fluid into duct
Inventor: DIVOUX MICHEL
IPC: D06B23/16
Filed: 1975-04-07
Abstract: A material to be treated to two separate processes in two separate treatment chambers passes from one chamber to the other chamber through a duct which is slightly larger than the dimensions of the material. A seal between the chambers is effected by injecting sealing fluid into the duct via distribution chambers connecting with the duct. The pressure of the sealing fluid is greater than the highest pressure existing in either chamber. The device is used for treating e.g. textile webs, natural or synthetic yarns; metal wires or sheets; semi-conductors etc. The material can move continuously from one process to another without an intermediate stage, thereby speeding up operation.

Title: Gas analysis by conductimetric cell - using recycled deionised water with ion exchange resin under reduced pressure
IPC: G01N27/06
Filed: 1975-04-10
Abstract: The conductimetric analysis of gases comprises (1) deionising a soln. (esp. water) by passing it through an ion-exchange resin bed (2) mixing the soln. with the gas at a pressure of 100-700 min. Hg (3) passing the resulting soln. through a conductimetric cell (4) measuring the electrical conductivity of the soln. and (5) recycling the soln. through the resin bed. The method is for the detection and determination of water soluble gases. The use of a reduced pressure in forming the bubble stream enables the sensitivity of the appts. to be reduced by altering the saturation level for the gas. The range of application of the method is thus greater (cf prior art) and it can be used e.g. to detect the CO2 concn. in exhaled breath.

Title: Mesh sheets used as packing to distribute fluids - have spaced oversize threads making them self-spacing and self-supporting
IPC: F28F25/08
Filed: 1975-12-19
Abstract: A packed body for distributing fluids, at least one of which is a liq., includes sheets of interwoven mesh for the packing. Alternate sheets of the mesh have one thread in each gp. of the warp threads parallel to the fluid flow, of a larger cross-section than the rest. This larger section thread is spaced every 2-10 threads. All the weft threads across the fluid flow are of the smaller cross-section. In instances where the fluids are to be kept separate sheets of mesh with the larger section threads can also be spaced between two continuous plates or can be positioned between two sheets of uniform mesh with continuous sheets on the outer side of the uniform mesh sheets. The passages formed between the mesh sheets with larger section threads and the uniform mesh or continuous sheets make up the fluid flow area. The body contg. the mesh sheets as packing has distributors to ensure that the fluids flow down their respective passages. Used for packing in distn. columns or scrubbers, e.g. wet scrubbers for removing particles from flue gases. The mesh sheets can be assembled without spacers and the larger section threads touch adjacent sheets at regular intervals giving adequate mutual support.

IPC: H04N3/18
Filed: 1976-02-16
Abstract: The electron beam of a cathode ray tube is deflected vertically by a circuit (8, 13 - 14) which operates with high efficiency and low power requirement. The driving power of the circuit (8, 13 - 14) is coupled to the vertical deflection coil (18) via circuit elements (13, 17), in the form of pulses derived from the horizontal deflection wave. The pulses in the first part of the vertical sweep interval are of one polarity and become continuously smaller, whereas in the second part of the vertical sweep interval they are of the other polarity and become continuously larger, so that the current in saw-tooth form (26) is generated.

Title: Car warning generator using radio - with broadband generator responsive to other cars horn to overcome sound insulation of car body
IPC: G08B1/08
Filed: 1976-03-24
Abstract: The warning generator produces a whistle or other sound on a car radio in response to the sound of the horn of another car. A broadband signal generator (11) is coupled via a BP shaping filter (13) to a modulator (15). The modulator modulates the roadband signal with the output of an oscillator (17) whose frequency lies in the radio band and which is controlled by the receipt of an audio signal. The modulator output is used to modulate a carrier-wave (21) which is then BP filtered and amplified to produce the interference signal. This signal is transmitted to produce the warning tone on other car radios.
