Title: Magnetic core switching circuit
IPC: H03K17/80
Filed: 1959-09-11
Abstract: 897,092. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. Sept. 11, 1959 [Sept. 12, 1958], No. 31039/59. Class 40 (9). Series-connected input coils 3, 4, Fig. 1, and series-connected output coils 3<SP>1</SP>, 4<SP>1</SP> are wound one on each core 1, 2 and a control winding 5 is wound on both cores, the arrangement being such that equal and opposite transients are induced in the series-connected coils by a control pulse, thereby eliminating the effect of the transients. A switching element coupled between an input/output circuit for a magnetic recording drum and one of the read/write heads of the drum comprises coils 3, 3<SP>1</SP> and 4, 4<SP>1</SP> wound diametrically opposite one another on ferrite cores 1, 2 and having between them a common saturation control winding 5. Assuming no saturating current is passing through winding 5, information signals may pass between the coils 3, 4 and 3<SP>1</SP>, 4<SP>1</SP> in either direction. On passage through winding 5 of a saturating rectangular pulse for track selection purposes, the information signals are blocked by saturation of the core but coils 3, 4 and 3<SP>1</SP>, 4<SP>1</SP> being in series opposition cancel any transients induced in the respective circuits. The write pulses W, Fig. 4, applied to the input are square topped and the read pulses R are sinusoidal, the sinusoidal pulses being of considerably smaller amplitude than the write pulses. Phase modulation is used to represent " binary bits " (0 and 1). The control pulses are of relatively long duration. Where the information pulses have a D.C. component a reset pulse is introduced into the control winding. Coils 3, 4 (also 3<SP>1</SP>, 4<SP>1</SP>) may be wound from the same length of wire and placed on cores 1, 2 in a similar manner, core 2 then being inverted and winding 5 wound about both cores.

Title: Process for the production of amino carboxylic acids
Inventor: ITIN MARCO
IPC: C07D201/16
Filed: 1955-10-31
Abstract: Amino carboxylic acids are prepared by treating aqueous solutions of the corresponding lactams with a sulphonated resin cation exchanger and separating the resulting amino carboxylic acid therefrom by treatment with ammonia solution.  The process may be carried out continuously and the resulting ammonia solutions of the amino carboxylic acids may be concentrated by repeated use in the separation stage.  The aminocarboxylic acids are preferably obtained from their weak ammoniacal solutions by evaporation at low temperature in vacuo.  Nuclear sulphonated polystyroles are specified as cation exchangers.  The lactam starting material may be dissolved in water alone or in a mixture of water with a miscible organic solvent such as an alcohol.  The examples describe the preparation of e -amino caproic acid from e -caprolactam.

Title: Rechargeable electrodes utilizing unsintered fluorocarbon binder
Inventor: RAMPEL GUY
IPC: H01M4/04
Filed: 1969-06-23
Abstract: 1,268,713. Rechargeable electrodes. GENERAL ELECTRIC CO. 23 June, 1969 [3 July, 1968], No. 31663/69. Heading HlB. Rechargeable electrodes are prepared by associating a current collector with a finely divided active material, intimately associating the active material with a dispersion in a liquid carrier of a fibrous linear hydrophobic fluorocarbon polymer and irreversibly breaking the suspension at atemperaturebelowthesintering temperature of the polymer to form a cohesive body comprising the active material and a fibrous interconnecting matrix of the polymer. The active material and the polymer can be associated to form a cohesive paste which is applied to the current collector or the active material on the current collector can be impregnated with the dispersion. The dispersion is broken by heating below the sintering temperature to volatilize the carrier (usually water) or by freezing followed by thawing or by increasing the pH or by solvent extraction of the carrier. Any surfactant in the dispersion is removed in the heating step or by washing. The active material may be Zn ZnO, Cd, CdO, Ni, NiO, Cu, CuO, Ag, Ag20 or HgO. When Zn is used in the formation of pasted electrodes either the surfactant is left in the paste until after the pasting operation or more preferably the paste is lubricated by amalgamation of the Zn and/or by the replacement of some Zn by ZnO.

Title: Improvements in multi-stage impulse turbines for steam or gas
IPC: F01D1/04
Filed: 1922-11-21
Abstract: 189,457. Akt.-Ges. Brown, Boveri, et Cie. Nov. 26, 1921, [Convention date]. Axial-flow type.-In order to dispense with, or reduce the number of, the fixed partitions separating the pressure stages of a multi-stage impulse turbine, the inlet and outlet edges of the stator guide-blades c terminate nearer the shaft than the edges of the adjacent wheel blades b, with the result that the motive fluid entering the guide-blades c has a suction action on the space e, and on passing out has a pressure action on the space between the two wheels, thereby equalizing the pressure throughout the space to a value p<11> lying between the values p<2>, p<3> on either side of the guide-blades, and obviating the need for a partition. The wheel rim may be provided with projections h, i for deflecting the stream of motive fluid towards and awav from the guide members. The axial thrust is taken by thrust bearing, or by a balance piston, or by a duplex arrangement of the turbine. Impulse stages without partitions may be combined in the same casing with either impulse stages fitted with partitions, a reaction turbine of the kind described in Specification 175,971, or with both. As described in Specification 124,734, in connection with reaction turbines, the guide blades may be made much wider than the wheel blades to permit of increased width for the wheel hubs.
