Title: Magnetic recording and reproduction of sounds and like signals
IPC: G11B5/64
Filed: 1946-01-24
Abstract: In a method of producing an austenitic steel wire or tape for magnetic records (see Groups XXII and XXXVIII), an annealed austenitic stainless steel wire or tape is cold-worked to such a degree that the crystalline lattice strains are not relieved to any appreciable extent, preferably to such a stage that the carbides are just about to be precipitated.  They may then be heat treated to produce a material having a ratio R of inductive coercivity to remanence of not less than .15.  Graphs, Figs. 3-7 (not shown), show the variation of remanence and inductive coercivity (a) when 12 per cent Cr-12 per cent Ni steel is heated to temperatures of 510 DEG -480 DEG C. respectively; (b) with time when 12 per cent Cr-12 per cent Ni steels of different tensile strengths and of different degrees of cold-working, are heated at 510 DEG C. for different periods (and then water quenched) up to 30 minutes; (c) when 12 per cent Cr-12 per cent Ni steels are heated for 5 minutes at temperatures ranging from 450 DEG C.-650 DEG C. and then water quenched; (d) when 18 per cent Cr-8 per cent Ni steels are heated for 5 minutes at temperatures ranging from 450 DEG C.-850 DEG C. and then water quenched.

[Class 138(ii)] An ironing-machine comprises a roll 6, a relatively-movable shoe 7 which is disposed between the roll and the position normally occupied by the operator and is of a girth not greater than 15 inches so that it may receive telescopically a sleeve of a man's shirt of a normal range of sizes, and a support 10 at the end of the shoe having a girth substantially the same as, or less than, the girth of the shoe at least for a length sufficient to accommodate in bunched form thereon a sleeve of the shirt, said shoe and support being peripherally unobstructed to enable the sleeve to be drawn on to the shoe and support. The padded roll 6 is supported at one end, in the construction shown in Figs 1 and 2, by the lateral arm 8 at the top of an upright 9 which is pivoted at 12 to the base 5; the support 10 for the shoe 7 is pivoted to the base at 11. An operating handle 13 for moving the shoe and roll towards and away from each other is pivoted to the lower end of the upright 9 and connected by a link 16 to the lower end of the upright 10. For driving the roll, an electric motor 18 and reduction gear 19, Fig. 3, are mounted inside the roll on a hollow shaft 20. This shaft carries bearings 22 for spiders 21 for supporting the roll, and is carried by a sleeve 23 on the arm 8 of the support 9. The shoe 7 comprises an openended hollow casing 31, Fig. 6, which is made of insulating material and is provided on its inner face with an electric heating-element 32 covered by a metallic ironing surface 33. In a modified construction (Figs. 7 and 8, not shown), the roll is carried on a fixed support and the shoe, which is supported on a pivoted upright at the opposite end of the machine, is movable to and from the roll by a lever pivoted to the base and connected by a link with the lower end of the pivoted upright. In operation, one sleeve and the body of the garment being ironed are telescoped over the shoe so as to be arranged in bunched position over the shoe support, and the second sleeve is then telescoped into ironing position on the shoe. One half of the latter sleeve is then ironed, after which the shoe is withdrawn in order to permit the sleeve to be positioned for ironing the other half; this sleeve is then withdrawn so as to permit the ironing of, first, the body portion of the garment and, then, the other sleeve. Operation of the handle 13 is effective to start rotation of the roll and control the heating resistance of the element 32.

Title: Improvements in or relating to the treatment of straw, hay, grass, reeds and like materials for the production of animal food stuffs
IPC: A23K10/32
Filed: 1940-04-15
Abstract: 541,960. Food for animals; apparatus for preparation of pulp; obtaining cellulose. PRICE, H. T. April 15, 1940, No. 2877. [Class 5 (ii)]- [Also in Groups IV and VIII] Compressed bales of straw, hay, grass, reeds, megasse, &c. with or without cereals or protein, are charged into digesters 1, 2, water at about 212‹F. and under pressure of 200-600 1bs. per square inch is admitted to digester 1 through inlet 3, air escapes through a cock 3a, and the straw is allowed to soak for 15 minutes to 1 hour; before the introduction of the water, the air may be drawn off. The water, containing various matters in solution, is drawn off into a tank 14 and thence pumped into digester 2, fresh hot water being added to this digester. When the straw in digester 2 has soaked, the soaked straw in each digester is heated either by hot gases supplied to the outside of the digesters from, e.g. a boiler 6 or, as shown by steam from the boiler which enters the digesters via cocks 5,. leaves by cocks 5a, is superheated at 7 and re-enters via pipes 9. Excess steam from digester 1 may preheat the straw in digester 2. By this treatment the straw is disrupted and softened. The treated'straw is passed to a disintegrator where it is converted into a meal, and then dried. The dryer 15 may be heated by steam from a digester. The liquid from the digesters is added to the straw before or during the disintegrating or drying operations. Liquid separated during disintegration may be returned before or during drying. Carbohydrates condensed from the steam may be returned to the disintegrator. If a higher proportion of nutritious matter is required in the finished material than was contained in the original straw, some of the straw, for example that charged into digester 1, may be used for paper-making, the liquid with which it has been treated being passed to the disintegrator.

Abstract: 1,211,333. Fuel batteries; secondary batteries; preventing corrosion. VARTA A.G. 17 Jan., 1969 [25 Jan., 1968], No. 2903/69. Heading H1B. [Also in Division C7] A corrodible part of the electrolyte circuit of an electrochemical device which comprises at least one negative electrode or hydrogen diffusion electrode having an electrochemical potential approaching the reversible hydrogen potential, is protected against corrosion by an additional electrode having the same electrochemical character as the negative or hydrogen diffusion electrode which is connected to the electrolyte circuit and to the corrodible part. The corrodible part is one which does not corrode in the electrolyte until the potential is more positive than the hydrogen potential. Preferably a second additional electrode placed on the opposite side of the corrodible part in the electrolyte system is connected to the first additional electrode. The second additional electrode may be replaced by the most negative electrode in the device which is then connected to the first additional electrode. Ionic conduction between the additional electrode and the most positive electrode in the device is reduced by making the thread of electrolyte between the two in the electrolyte circuit of high electrical resistance. The additional electrode can be conductively connected to the positive electrode through a resistance. As shown in Fig. 1, a fuel-battery electrolyte cooler 8 is protected by additional hydrogen electrode 6 connected thereto. Corrosion protection of a MeOH/O 2  fuel battery and a Ni/Cd alkaline battery with circulating electrolyte (Figs. 4 and 6, not shown). In the latter case the additional electrode is a hydrogen electrode supplied with hydrogen by an electrolyser powered by the battery.

A variable resistance device of the continuous rotation type includes a toroidal support, a coil having a plurality of turns wound on the support and consisting of a live portion and a dead portion, and a contact member in sliding contact with successive turns of the coil along a contact path, the turn at each end of the dead portion being severed at a point not on the contact path, and the number of turns in the dead portion being greater than the number of turns simultaneously engageable by the contact member. A resistance element 19 (Figs. 2, 4) comprises a helical winding of resistance wire 30 extending over substantially the whole length of a toroidal support 28 (Fig. 1). A terminal lead 70 is near but spaced from one end of the wire 30 and a terminal lead 71 is near but spaced from the other end of the wire 30. The wire 30 is severed between each lead and the adjacent wire end. Preferably a plurality of severed points 75 are provided at each end. Before severing the wire 30 a coating 58 (Fig. 3) of enamel is applied over 270 degrees of the surface of support 20 to prevent displacement of the turns. Alternatively, the entire surface of the support 20 may first be coated with enamel and a portion of enamel extending over 90 degrees removed. The toroid is preferably of enamelled copper wire, the enamel being polyvinyl formal polyester or phenolic epoxy resin. Severing of the wire 30 is performed under the enamel coating 58 by a sharp-edged tool 76, Fig. 5, or by contacting electrical leads 77, 78 to adjacent regions of a single turn of wire and " blowing " the section between the leads with current from a source 80. The resistance element is situated in a two-part housing 10 (Fig. 1) together with a wiper 51 (Fig. 2). The wiper 51 is continuously rotatable by a shaft 31 and the wiper moves equally smoothly over the live and dead portions. Electrical connection from a terminal 55 to the wiper 51 is provided by a brush 56 riding on a bush 50 which also serves to attach wiper contact arm 39 to a block 33 carried by shaft 31. The resistance element 19 is made by providing an elongate deformable core, helically winding resistance wire on the core and bending the core to form a substantially closed ring.

Title: Improvements in or relating to machines and methods for corrugating tubes
Inventor: PENROSE JAMES RONALD
IPC: H01B13/00
Filed: 1954-02-01
Abstract: 791,514. Corrugating. GENERAL ELECTRIC CO., Ltd. Jan. 31, 1955 [Feb. 1, 1954], No. 2943/54. Class 83 (4). A tube is helically corrugated by the relative rotation around the tube and in engagement therewith of a member, having a concave working surface lying in a plane inclined to a plane perpendicular to the axis of the tube, as the tube moves axially relative to the corrugating member. Stainless steel tubing 8 is secured at one end in a clamp 24 which is advanced by a lead screw to push the tube through a corrugating head 7 rotated around the tubing 8 by a sleeve 14. An annular corrugating member 1 carried by the head 7 is mounted in bearings 4, in a block 9 adjustable in the head 7 by a screw 10 to vary the eccentricity of the annular member 1 with respect to the tubing 8 to be corrugated. The annular corrugating member 1 is inclined, at the helix angle to be given to the corrugations, to a plane normal to the axis of the tubing. The diameter of the circular aperture in the annular member 1 may be less than of the overall diameter of the corrugated tube or if a portion of the tubing is to be passed through the head 7 without corrugation, the aperture may be larger than the diameter of the uncorrugated tube. The radius of curvature of the profile of the rim of the aperture is less than the desired radius of curvature at the root of the corrugations. The tubing 8 is supported just prior to the point of corrugation by an external bush 19 and an internal mandrel 22, tubular or solid and of steel or wood, which latter may be loose in the tubing 8 being urged back by the squeezing action of the corrugating member, such movement being resisted by the frictional engagement with the tubing or by fluid pressure or spring means. Alternatively, as shown, a steel rod 23 which may carry the mandrel 22, may be fixed by a clamp 27. The head 7 may carry more than one corrugating tool arranged to act successively. The tool 1 may comprise a part annular member 1, Fig. 5, rotated around the tubing, which member may have a working surface in the form of a parabola or part of an Archimedean spiral subtending 180 degrees with the radius of curvature decreasing from the uncorrugated to the corrugated part of the tube. The tube 8 may be rotated and the tool 1 kept stationary. The machine may be coupled to tube forming and welding apparatus. Specification 791,513 is referred to.
