Title: Improvements in or relating to secondary electric batteries
IPC: H01M50/566
Filed: 1950-12-06
Abstract: 701,642. Batteries ; direct connections between conductors. YARDENY INTERNATIONAL CORPORATION. Dec. 6, 1950 [Dec. 6, 1949], No. 29914/50. Classes 38 (1) and 53 An accumulator is provided with a valved gas exit comprising a perforated seat 27 in the cover which is normally closed by a ball 30 pressed against the seat by a plug 29 of sponge rubber. Below the gas exit is a loose baffle 43 resting on a felt strip 44 supported on the electrodes. The latter may consist of a negative plate 24 of compressed powdered zinc or zinc oxide surrounded by wrappings of absorbent paper and regenerated cellulose. The zinc oxide may be made into a paste with kaolin and electrolyte which may be a solution of caustic potash. Embracing the negative electrode on two faces is the positive electrode 23 which consists of powdered silver or its oxide enclosed in regenerated cellulose wrappings. The terminal wires 35, 36 leading from the electrodes are connected by solder 39 to terminal caps 37 which rest on washers 41. Fig. 7 shows a modification in which the gas exit 127 is situated at the bottom of the battery and is closed by a plug of sponge rubber 129. A loose baffle 143 is supported by three legs 106 and carries a felt disc 144, an apertured spacer 108 and the positive and negative electrodes 123, 124, the latter of which is connected to a metal cap 101 through solder 139, a metal insert 137 and a spring washer 104. Before insertion in the battery the positive electrode is prepared by suspending it in a bath of electrolyte contained in an outer vessel from which the air can be exhausted to remove air from the electrode and cause it to become saturated with electrolyte. Figs. 5 and 6 show a method of connecting the wire 35 to the cap 37. Pieces of solder 39<SP>1</SP> are introduced into the inverted cap and the cover of the battery 'carrying the wire 35 lowered till the boss 31 enters'the cap and causes the wire to buckle. The cover is then inverted into the position shown in Fig. 6 and the solder melted by heating electrodes 52, 53, pressure being simultaneously applied by a member 51 to force the cap into contact with the washer 41. Specifications 680,793, 682,164, 682,165, 698,405, 701,641 and 701,644 are referred to.

Title: An improved process for the continuous separation of sulphur from sulphur solutions
IPC: C01B17/033
Filed: 1925-11-26
Abstract: 249,044. Legeler, E. July 6. 1925. [Convention date]. Sulphur.-In a process for the continuous separation of sulphur from sulphur solutions, the solution is introduced into a vessel G heated on all sides and in this vessel is allowed to drip on to a device B which is heated up to the boiling-point of the solvent and at least up to the melting-point of the sulphur. The device B, which may be in the form of a segment of a sphere or a double-walled sieve, or may be conical or the like, vaporizes the solvent, which passes away through the pipe C and melts the sulphur which runs down to the bottom of the chamber for continuous or intermittent removal.

Title: Improved vibration damper
IPC: F16F7/112
Filed: 1955-10-20
Abstract: 771,048. Damped dynamic vibration absorbers. GENERAL MOTORS CORPORATION. Oct. 20, 1955 [Nov. 15, 1954], No. 29995/55. Class 108(3). A vibration damper comprises a closed cylinder 12 having a concentric hollow shaft 24 on which an annular weight 26 is slidably disposed and resiliently held between the ends of the cylinder, the weight 26 having an external seal 56 to engage the inner wall of the cylinder 12 to divide the latter into two chambers 62 and 64, which are connected through ports 58 and 60 leading to the interior of the shaft 24. As shown, the weight 26 has a threaded extension 28 by means of which it is connected to a coil spring 32, the other end of which is threadedly connected to a member 36 rigid with the end of the cylinder 12. The weight 26 has upper and lower bearings 48, 50, which frictionally engage the shaft 24. In a modification, Fig. 4 (not shown), the weight 26 is mounted between upper and lower springs 32. In operation, high-frequency low-amplitude oscillations experienced by the cylinder 12, result in out-of-phase oscillations of the weight 26 which are damped by flow of air through the ports 58 and 60. This action causes a fine mist to be formed between the air and a small quantity of lubricant which is contained in the cylinder.

Abstract: 394,863. Motors. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Oct. 27, 1932, No. 30158. Convention date, Aug. 19. [Class 35.] Motors with unwound iron armatures.-Some of the stator poles of a synchronous motor particularly for clock driving are movable to produce an unsymmetrical pole distribution whereby the motor can be made either self-starting or non-self-starting. The stator comprises an iron core 1 having pole-pieces 2, 3 at its ends. The ends of the pieces 2, 3 are divided to form poles 4.. 11 which extend through holes in a copper ring 13. Alternate holes in the ring 13 are interrupted by slots 14 so that there is a complete copper circuit around the poles 4, 7, 8, 11 whereby a rotating field is produced when the coil 15 is energized. The rotor consists of a toothed steel disc 16 made by stamping, the teeth 17 being bent as shown in Fig. 1. Alternatively it may consist of a number of connected discs. The stator poles 8 .. 11 of the pole-piece 3 are connected to a lever 20 capable of being rocked against a spring 24; the displacement of these poles reduces the locking tendency of the stator poles on the rotor teeth so that the motor can start asychronously by reason of the production of eddy currents in the rotor. Movement of the polepiece 3 may be effected electrically.

Abstract: 1340419 Porous coated materials SOC ITALIANA RESINE SIR SpA 30 June 1971 [1 July 1970] 30628/71 Heading B2E [Also in Division B5] Poromeric materials consist of non-woven fabric used as a backing, a coagulated foam intermediate layer and a micro porous polyurethane film attached to the intermediate layer, the intermediate layer being obtained by coagulating the foam obtained by entraining air in an aqueous latex having a polymer solids content of at least 45% by weight, the amount of air entrained being such that the volume ratio of latex air is from 2:1 to 1:2. The latex may comprise acrylic, methacrylic, vinyl, butadiene, styrene-butadiene or acrylonitrile polymers or copolymers of two or more of these monomers, or polyamides or polyurethanes. The films may be coagulated by heating, gelling, or irradiation. The poromeric materials may be produced by: a) spreading the foam onto a thin layer of micro-porous polyurethane film, coagulating the foam, and glueing a non-woven fabric under the surface of the coagulated foam; b) spreading the foam directly onto the non- woven fabric and applying the micro porous polyurethane surface coating, e.g. by glueing on a preformed micro porous layer or by forming the micro porous layer directly on the surface of the hardened foam, or by distributing small particles of polyurethane by a thousand-point stamping machine; or c) spreading the foam both onto the non-woven fabric and onto a thin layer of micro porous polyurethane film, drying the products and then combining them by rolling in a calender under heat with their foamy parts in contact. The fibres of the non-woven fabrics may be natural, e.g. cotton, wool or artificial, e.g. rayon or synthetic, e.g. polyamide, acrylic, polyester, alone or mixtures thereof.

On the slide 5 are two adjustable screwed push bars 22, 23 adapted to engage the ends of the slide 16, so that when the slide 5 nears the end of a stroke in one direction, the bar 22 pushes the slide 16 up its inclined groove, thus lifting the guide 12 to press the knife blade against the wheel 7. At the end of the reverse stroke of the slide 5, when the blade is ground, the bar 23 pushes the slide 16 down the groove, thus lowering the guide 12 so that the blade falls away from the wheel 7, and may be removed &c. ; the movement of the slide is stopped by engagement of the stops 20, 21 with the slide 19. The slide 19 is adjustable to compensate for wear of the wheel 7, and to bring the work into proper relation with the wheel.
