[Class 53] A battery consists of zinc and carbon plates with intervening layers of electrolyte and depolarizer arranged in the form of a sandwich, the edges of the battery being sealed with a thin elastic and waterproof skin applied by dipping, spraying or brushing. Rubber may be used for this purpose and several layers may be used alternating with layers of varnish, the outer layer consisting of a binder of any thickness. The varnish and binder may consist of an organic gum or resin with rubber, tar, bitumen, &c. The binder may be applied by placing the battery with the elastic skin applied in a container which is then filled with the binder. The rubber solution used for sealing may contain vulcanizing agents. The Provisional Specification states that the layers of electrolyte and depolarizer may be made by forcing the materials from separate containers through a slot-shaped nozzle. The ribbons so formed are superposed to form a tablet the edges of which may be coated with bituminous paint or a quick-drying dope. The electrolyte and depolarizer may alternatively be applied to open mesh tape or fabric, and the cells may be formed with spaces to receive a small quantity of liquid electrolyte.

Abstract: 934,844. Corrugating asbestos cement sheets. JOHNS-MANVILLE CORPORATION. March 31, 1962, No. 12477/62. Class 87(2). An uncured asbestos cement sheet is corrugated by placing it on a perforated fabric drawn tautly across a die, having a plurality of depressions and spaced sections, and applying a differential fluid pressure force on the fabric and sheet and moving the sections towards each other thus causing the fabric and sheet to enter the die depressions. The die A has logitudinally extending die boxes 1, 2 and 3 with box 1 being fixed and boxes 2 and 3 being mounted for lateral movement to and away from box 1 along spindles 21 and 40 by motors 32 (not shown). The box tops are formed of perforated metal sheets 4, 10, 14 to give the desired corrugated surface when the boxes are in their nearest positions to each other. A pliable perforated fabric sheet 49 such as neoprene coated glass cloth is stretched over surfaces 4, 10, 14 when boxes 2 and 3 are in their outwardly extended positions and secured by conventional means. An uncured asbestoscement sheet 51 is then laid over the fabric 49 and a vacuum is applied to the box system via perforated walls 6, 12, 17 from a source 52 (not shown), with motors 32 holding boxes 2 and 3 in their extended position to force the sheet against the fabric. The motors are reversed and the unit is closed towards stops 60 and 57 pulling the sheet 51 in towards the contours of the curved depressed sections of the upper surfaces. When boxes 2 and 3 have reached their innermost position relative to each other thus forming a complete set of depressions the vacuum is destroyed and the sheet removed for curing.

Filed: 1942-09-09
Abstract: 556,999. Roll-film adapters for cameras. JOHNSON, N. G. Sept. 9, 1942, No. 12711. [Class 98 (i)] An adapter for the use of kinematograph film with plate and film pack cameras comprises a casing a in which are provided means for the reception of a cassette e, mechanism for feeding the film through the required distance for each exposure and for re-winding it into the cassette, and a removable frame c by which the adaptor is secured to the camera. The frame c includes a slide c<SP>1</SP> and a mask defining the exposure area, which is formed in the case shown by a plate d which fits in the runners on the back of the camera and is provided with an exposure aperture d<SP>1</SP>. The frame c is interchangeable with others for use with different cameras. The film winding mechanism shown comprises a take-up spool f rotated by an external knob which also, through a slipping clutch and gears h, i, rotates a shaft j carrying sprockets which engage in the film perforations. When the required length of film has been fed, as the result of one revolution of the shaft j, the movement is arrested by a pin n on the wheel i engaging the arm o<SP>2</SP> of a bellcrank lever. This lever is turned by an external knob to the inoperative position shown in broken lines when the film is again to be fed, and returned during feeding to the locking position by the engagement of the pin n wih the other arm o<SP>1</SP>. A counting-disc is frictionally driven by the winding-knob, which advances it at each setting owing to the gear h having one tooth less than the gear i so that the winding knob makes slighly more than one revolution. When the film is to be re-wound a roller s which is carried by pivoted arms is moved from the full-line to the broken-line position, in which it disengages the film from the sprockets.

Title: Means for breaking up air flow over streamline bodies
IPC: H01Q19/12
Filed: 1944-07-06
Abstract: 582,598. Aerials. BRITISH THOMSON-HOUSTON CO., Ltd., and BOWEN, A. July 6, 1944, No. 12932. [Class 40 (v)] Undesired forces on a body subjected to air flow such as a parabolic aerial reflector, are reduced by means comprising a fixed fin located behind the leading edge and extending approximately normal to the surface, for breaking up the streamline flow of air over the body. The parabolic reflector 1 associated with the dipole 2 is mounted on a head 3 which is in turn mounted for rotation about a vertical axis on pillar 4, the centre of mass of the reflector being displaced from the pillar axis. The force produced by wind provides a torque, which is only zero when the centre of mass of the mirror and pillar axis lie along the wind direction, and tends to increase the speed of rotation on one side of the pillar and decrease it on the other side. The ring 5 attached to the outer surface of the reflector substantially normal to the surface, disturbs the streamline flow over the reflector and reduces this additional variable torque imposed on the reflector during rotation.

Title: Manufacture of new basic products
IPC: C08G73/02
Filed: 1936-05-07
Abstract: Basic products are made by reacting the primary amide of a carboxylic acid derived from a naturally occurring oil, fat, or wax or a mixture of such amides with three or more molecular proportions of ethylene imine at elevated temperature, if desired in presence of a catalyst. The products may combine with acids to form salts.  Catalysts specified are sodium hydroxide or a surface-active substance such as silica gel or kieselguhr.  Three to forty molecular proportions of ethylene imine are preferred, but larger quantities may be used. Primary amides of the following acids are specified; caproic, caprylic, capric, lauric, myristic, palmitic, stearic, hydroxystearic, oleic, linoleic, linolenic, ricinoleic, elaidic, undecylenic and erucic, and mixtures of these acids derived from natural oils such as coconut oil, palm oil, palm-kernel oil, rapeseed oil, linseed oil, cotton seed oil, the acids obtainable by fat hydrogenation processes, and the acids of waxes of vegetable, animal, or mineral origin such as beeswax, carnauba wax, montan wax.  Salts of the products may be formed by treatment with aqueous acids or by dissolving in an organic solvent, such as benzene, chloroform or ethanol, and treatment with acids, e.g. by passing in gaseous hydrogen chloride.  The aqueous solutions of the salts are useful in textile treatment processes.  In an example, stearic acid amide is heated to 130 DEG  C. for 10 hours with ethylene imine in presence of aqueous sodium hydroxide; the product is dissolved in ethanol and treated with hydrogen chloride.  Samples have been furnished under Sect. 2 (5) of products prepared by (A) reacting mixed amides derived from the fatty acids of coconut oil with five molecular proportions of ethylene imine in a closed vessel for 12 hours at 130 DEG  C. in presence of a little water to give a basic intermediate product, which is then treated with hydrogen chloride in ethanol and acetone; (B) reacting the intermediate product under (A) with a further five molecular proportions of ethylene imine; (C) reacting the product obtained under B with a further five molecular proportions of ethylene imine; (D) dissolving the product of (C) in acetone and treating with hydrogen chloride; (E) reacting lauric acid amide with five proportions of ethylene imine and a little water in a closed vessel at 160 DEG  C. for 14 hours, and then reacting the product with a further five proportions of ethylene imine.  These products are stated to be foaming agents.
