Inventor: HALL CLIFFORD JAMES
IPC: H01M4/23
Filed: 1959-05-01
Abstract: 871,348. Batteries. CHLORIDE BATTERIES Ltd. April 5, 1960 [May 1, 1959], No. 14901/59. Drawings to Specification. Class 53. A lead-acid accumulator which can be stored in the dry charged state has a negative plate in which the particles of reduced lead are protected against oxidation by a coating of a lead soap. The coating may be made by mixing a fatty acid with the lead oxide and sulphuric acid with which the negative electrode is pasted. The fatty acid may have a melting-point below or above the temperature which the mixture attains; if it is above, the acid may be mixed as an aqueous emulsion with the lead oxide and sulphuric acid. After the electrode has been formed electrolytically the particles of reduced lead remain coated with the soap formed by the reaction of the lead oxide with the fatty acid. The fatty acid preferably contains at least ten carbon atoms and may be saturated or unsaturated, for example stearic, palmitic or oleic acid. Substituted fatty acids may also be used, for example hydroxystearic acid and ricinoleic acids. The quantity of acid used is from 0.02 to 0.25% of the weight of the lead oxide. The negative plate is inserted in a cell with a conventional positive plate, and when required for use the cell is filled with sulphuric acid of 35% concentration which decomposes the lead soap on the negative plate.

Title: Means for integrating the periods during which the arc voltage of an electric arc welding circuit is maintained between predetermined minimum and maximum values
IPC: B23K9/10
Filed: 1946-05-17
Abstract: 619,963. Supply meters; current and duration meters. QUASI-ARC CO., Ltd., and OLIVER, J.-R. May 17, 1946, No. 14949. [Class 37] Means for integrating the period during which the arc voltage of an electric arc welding circuit 19 is maintained between predetermined minimum and maximum values comprises a time recorder 11, adapted to be connected to a source of energy independent of the arc welding circuit, and a relay system 16 and 17 associated with the welding circuit and operable to interrupt the transmission of energy from the source to the recorder wherever the arc voltage falls outside the predetermined values. A revolution counter 11 is driven by a constant speed motor 10 connected to a suitable source of current, two serially-connected switches 14 and 15 being included in one lead 12 from the motor 10 to the source. Two relays 16 and 17 are each connected across the arc welding terminals, and they are so selected that relay 16 closes switch 14 at a voltage across the arcwelding terminals of 60, and opens it at 10 volts, whilst relay 17 opens switch 15 at 60 volts, and closes it at 45 volts. Hence switches 14 and 15 are only both closed for voltages lying between 45 and 10, and hence it is only between these values that revolution counter 11 records the time. Alternatively, the revolution counter may be driven by a clockwork motor, the spindle of which carries a friction disc co-operating with a brake operated by the relays. The mechanical arrangement is such that the brake is only inoperative between voltages of 45 to 10.

Title: Improvements in or relating to electro-mechanical transducers employing dielectric elements
IPC: H04R17/00
Filed: 1949-06-03
Abstract: 663,423. Piezo-electric crystals. BRUSH DEVELOPMENT CO. June 3, 1949 [June 12, 1948], No. 14949/49. Class 40 (viii). A piezo-electric element comprises a body of polycrystalline dielectric of generally tubular form arranged so that bending of the tube about its central axis causes extension of one portion of the side wall and compression of the opposite portion of the side wall to generate opposite voltages between pairs of electrodes mounted on the inside and outside surfaces of the side wall portions. In Figs. 1 and 3, a cylindrical element 21 of pre-polarized titanate ceramic is fixed to a base 22 and has oppositely arranged external electrodes 29, 30 and a continuous internal electrode 28. A shaft 23 extending from a cap 24 fixed on the free end of the element may cause bending of the cylinder about its longitudinal axis, to compress one side wall and simultaneously extend the opposite side wall. This generates voltages of opposite polarity on electrodes 29, 30. In a modification, Figs. 4-6 (not shown), the element is tapered from the base towards the free end, to give uniform stress distribution on bending. In Fig. 7 the element is in the form of a tube curved through a semi-circle, and fixed at one end to a base 42. Oppositely placed electrodes 49, 50 co-operate with an internal electrode (not shown). As thus arranged the cumulative bending movement due to an applied voltage produces a movement of the free end in a direction at 58 degrees to the transverse section of the free end, that is, along the length of a shaft 43. In a further embodiment, Fig. 12, the element is in the form of a flattened tube 51 of barium titanate having a single internal electrode 78, and a pair of external electrodes 79, 80. Then, on bending, one side wall is stretched while the other wall is compressed thus giving opposite voltages on the outer electrodes. The ends of the element are connected respectively to a stylus yoke and to a base as described in Specification 663,421. The tubular elements may be made by the method described in Specification 663,424. Specifications 648,403, 648,404, 659,869, [Group XL (c)], and 663,422, are referred to.
