Title: Improvements relating to diaphragms for use in ion exchange processes
Inventor: HONEY ERIC MAURICE O'CONNER
IPC: C08J5/22
Filed: 1953-05-18
Abstract: Diaphragms for use in electrolytic and ion-exchange processes are produced by incorporating in a thermoplastic polymer fine granules of an ion-exchange resin with the aid of a solvent which gels the thermoplastic polymer to produce a dough, shaping the latter as by extrusion, sheeting or calendering into diaphragm form, and removing the solvent by evaporation.  The polymer may be polyvinyl chloride, a copolymer of vinyl chloride and vinyl acetate or vinylidene chloride or polyethylene, and the solvent may be dimethyl cyclohexanone, butyl acetate or xylene, which may contain a diluent such as white spirit. Polypropylene sebacate may be incorporated as plasticizer.  The mixture from which the dough is made may contain a leachable ingredient such as sodium chloride which may be removed after evaporation of the solvent so that the diaphragm contains pores through which liquids may diffuse.  The ion-exchange resin may be a cation exchange resin of the phenolic type containing nuclear sulphonic hydroxyl groups or an anion exchange resin of the phenolic type containing amino and phenolic hydroxyl groups.  Reference has been directed by the Comptroller to Specifications 719,315 and 721,161.

Title: Improvements in the commutation of contact converters
IPC: H02M7/62
Filed: 1953-05-13
Abstract: 783,209. Converting. WIDAKOWICH, M. May 13, 1955 [May 14, 1954], No. 13870/55. Class 38 (2). In a converting circuit in which a load 11 having in parallel a capacitor 12 is supplied with A.C. from a D.C. source 8, 9 through vibratory reversing switch 1, operation is improved by connecting in the circuit so as to carry load current in one direction only, an inductor 10 which, preferably, is unsaturated upon closure of the contacts and tends to saturation upon opening. Rectifier 13 in parallel with the inductor allows dissipation of the energy stored in the latter. The resistance of the circuit 10, 13 is reduced to decrease the voltage rise on contact opening, and to allow time for complete dissipation of energy before, the inductor carries more current, an inductor-rectifier circuit may be connected in each side of the supply, Fig. 2 (not shown). In a modification, rectifier 13 is connected in series with a capacitor across the two input contacts of the converter. Each component is shunted by an impedance so that the voltage across the capacitor is that of the supply, Fig. 3 (not shown). Capacitor 14 stabilizes the input voltage. The inductor core may be premagnetized, e.g. by a permanent magnet or have a small air gap.

Abstract: 424,332. Conductors for dynamoelectric machines. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin) May 15, 1933, No. 14079. Convention date, May 14, 1932. [Class 35] The invention relates to the stator windings of alternating current machines and its object is to overcome the lack of uniformity of current distribution due to end stray fields in the end connectors which are divided axially and disposed in two banks or planes. It is explained that the end stray field has two components, namely, one due to the current in the conductor itself and another due to currents in the adjacent connector plane. According to the invention, the ends of the connector sections are kept separate from each other at one end at least of the connector and joined through sectional slot conductors or conductor groups to corresponding connector sections at the other end of the machine whereby E.M.F. differences at one end of the machine due to one of the stray field components are opposed by similar E.M.F.'s at the other end of the machine whilst the second component of stray field is compensated within each connector by transposition of its parallel sections. Figs. 2b, 2<c> show the two ends of a subdivided slot conductor c joined to involute end connectors which are also subdivided and arranged in two axial planes. The fields due to the currents in the connectors themselves are represented in direction and magnitude by the small diagrams E<1>, E<2> and the fields due to currents in the adjacent connector planes by the diagrams F<1>, F<2>. By means of the transposition at k, the effects of the fields E<1>, E<2> are compensated within each end connector, and by means of the transposition at h, the effect of the fields F<1>, F<2> at one end is opposed by the corresponding effect at the other end. Connections are also described in which the effects of the fields F<1>, F<2> are compensated within each involute and the effects of the E<1>, E<2> fields at one end of the machine are opposed by those at the other end.

Title: Improvements in high-frequency signalling systems
IPC: H03H2/00
Filed: 1938-05-11
Abstract: 514,641. Valve circuits for wireless reception. JOHNSON LABORATORIES, Inc. May 11, 1938, No. 14079. Convention date, May 17, 1937. [Classes 40 (iii) and 40 (v)] [Also in Group XXXV] In a radio receiver in which an aerial 6 is coupled to the first valve 8 through a parallel resonant circuit including capacity elements 4, 5 and an inductive element 2, tuning over a wide frequency range is effected by displacement of a magnetic core 3 relatively to the coil 2 and the core is so designed that the ratio of inductive reactance to resistance is substantially constant. This means that the resistance must vary inversely as the first power of the frequency and has the result -that the ratio of output to input voltage is substantially constant for all frequencies. The correct design is obtained by suitable choice of the shape of the core, the type and distribution of the magnetic material, and the kind of particle insulation and binder employed. In one design, the coil has a three-bank winding of 15/44 Litz wire and is 1.625 inches long and 0.34 inch in 'diameter, and the core is 1.875 inches long and 0.3125 inch in diameter, the end of the core which enters the coil first being of very finely-divided low-loss magnetic material and the remainder of a coarser and less-expensive material. As an alternative to the arrangement shown, the aerial may be connected to the junction of condenser 5 and coil 2, the junction of condensers 4, 5 and the cathode of the valve 8 being grounded.
