Abstract: 604,754. Thermal switches. PIERCE FOUNDATION, J. B. Nov. 8, 1944, No. 21965. Convention date, Jan. 8. [Class 38 (v)] In an overload circuit-breaker wherein overload causes a bimetallic current-carrying contact disc 29 to snap out of engagement with fixed contacts 12, compensation for variations of ambient temperature is provided by means of a second bimetallic disc 26. In the form shown, the switch, besides being responsive to overload, may be moved " on " or " off " by energization of a coil 14 or 15, the bimetal disc 26 acting then as a bowed snap spring to give a quick movement. When the switch has been opened by overload, the disc 29 remains in the dotted position on cooling, but may be reset by successive energizations of coils 15, 14.

Abstract: A process for carrying out reactions in which sodium borohydride is a reactant comprises using as a reaction medium a liquid, a minor proportion of which comprises one or more linear polyethers and a major component of which is a liquid in which sodium borohydride is substantially insoluble.  The linear polyether may be derived from diethylene, triethylene and tetraethylene glycols or di-, tri- and tetra-1:2-propylene glycols, dialkyl ethers of diethylene glycol, e.g. the dimethyl ether, being preferred.  Preferably the linear polyether constitutes 1-20% by weight of the major component.  The major component may be more volatile than the linear polyether component and may have a boiling point below 120 DEG C.  Specified major components are dimethyl ether, diethyl ether, tetrahydrofuran and tetrahydropyran and mixtures thereof, dioxan, hydrocarbons and halogenated hydrocarbons.  If desired the reactants may be brought together in the liquid which is the major component and thereafter the linear polyether may be added thereto.  In examples the use of sodium borohydride is described for the preparation of (1) diborane, (2) dichloroborane and (3) trimethylamine dichloroborane. Specification 873,267 is referred to.ALSO:A process for carrying out reactions in which sodium borohydride is a reactant comprises using as a reaction medium a liquid, a minor proportion of which comprises one or more linear polyethers and a major component of which is a liquid in which sodium borohydride is substantially insoluble.

IPC: C01B3/36
Filed: 1959-06-29
Abstract: 878,579. Producing town gas from natural gas. CONCH INTERNATIONAL METHANE Ltd. June 29, 1959, No. 22306/59. Drawings to Specification. Class 55 (2). The calorific value of a natural gas containing methane and heavier hydrocarbons is reduced by a process comprising the steps of separating at least a portion of the heavier hydrocarbons from the natural gas, converting the separated heavier hydrocarbons by partial combustion with air into a gas containing hydrogen and carbon monoxide and blending the thus produced gas with the natural gas from which the heavier hydrocarbons were separated. The gas containing hydrogen and carbon monoxide may be reacted with steam in the presence of a catalyst and the resulting gas with or without removal of carbon dioxide may be used to blend with the natural gas from which the heavier hydrocarbons were separated. The air and heavier hydrocarbons may be preheated to about 1,000‹ F. before partial combustion which is effected at a temperature of about 2,500‹ F. The air may be dried (see Group XIII) by washing with glycol before it is preheated. The natural gas may be in liquefied form and the separation of the heavier hydrocarbons may be effected by vaporizing the liquefied natural gas in a fractionating column (see Group XXVIII).

Abstract: 731,617. Transformers. ENGLISH ELECTRIC CO., Ltd. Sept. 4, 1953 [Sept. 5, 1952], No. 22380/52. Drawings to Specification. Class 38(2). A transformer has a high voltage winding which is split into a number of serially connected disc-like coils wound with round wire, each coil being wrapped-after being woundwith a conductive covering, one end of the covering being connected to an end of the coil whilst the other end of the coil is connected to the covering of the adjacent coil. Thus the covering of a coil constitutes an active turn of the coil and also serves as the connecting means between one coil and an adjacent one. Further, the conductive wrapping introduces capacity between the windings of each coil and the wrapping thereof. The wrapping may be a copper tape or an insulating tape coated on one side with a conductive layer.

Apparatus for producing optical images comprises an objective lens having a single light transmissive area and adjustable means effective over separate parts of that area to determine the lateral confines of those parts and/or to deflect or deviate light transmitted through one part in relation to that transmitted through another part. The kinematograph camera shown in Fig. 1 has shutter at 115, film at 11 and objective elements 19, 28 movable for focusing by means of a threaded ring 15 by means of which portions 13, 17 of the mount are relatively axially adjustable. Between the lens elements is a device indicated at 30, shown in elevation in Fig. 2, and comprising a number of diaphragm leaves 36, individually adjustable vertically by means of screw adjustment 33. The lower half of the lens aperture is covered by a mask 37. Also disposed between the lens elements is the device 23 comprising a number of narrow transparent parallel-sided strips 70, 71, 72, 73 extending the width of the lens. A worm gear adjustment mechanism provides equal but opposite rotation of the strips 71, 72 about their longitudinal axes with, at the same time, equal and opposite rotations of the strips 70, 73 also, the rotations of the latter being greater than of 71, 72.
