Patent GB-1045997-A (GB)
Title: Strands or yarns composed of coated filaments of heat softenable material
Inventor: JENKINS RICHARD GEORGE CHRISTO
IPC: D02G3/18
Filed: 1965-04-29
Abstract: Glass or synthetic resin fibres are coated with steel, zinc, copper aluminium, nickel, tin, lead or alloys e.g. Babbit metal including 14.1% antimony by draining them past electrically heated containers or the metal having slots in a graphite coating face.ALSO:Flexible, wear- and abrasion-resistant, coated multifilament yarns or cords e.g. for tyre reinforcement, are made by flowing streams of heat-softenable materials e.g. glass or synthetic resin, from a molten source, alternating the streams into continuous filaments and simultaneously separating them into two p  or more lineally moving groups, applying different coating materials to the filaments of different groups so that all filaments in each group are similarly coated, and collecting the group into a unitary assembly.  Some filaments of an assembly may be uncoated.  Yarns &c., may be twisted and/or intertwisted, formed into ropes or into woven or non-woven (net, scrim, mesh) fabrics in which the intersections of the yarns may be bonded or fused.  One or more of the coating materials may be metal e.g. zinc, copper, aluminium, nickel, tin, lead or alloys or combinations thereof (and which may form or be coated or plated with a protective or lubricating film of the metal chloride, phosphate, or sulphide, or graphite or of corrosion resistant metal such as indium) applied by evaporation, plating, chemical reduction or spray, or a synthetic resin e.g. polyamide, epoxy resin.  A synthetic resin may be applied to one group and a catalyst therefor e.g. hexamethylene, or to another group, or a resin and excess catalyst may be applied to one group and another resin, curable by the same catalyst, to another group, the or both resins being cured as by heating at any subsequent stage of the yarn or cord, rope or fabric formation.  Different component reactant materials e.g. solvent solution of adipyl chloride and an aqueous solution of hexane diamine, may be applied simultaneously or sequentially to one or each group and reacted subsequently to form a synthetic resin which may fix or bond the filaments.  If the yarn (or products thereof) contain a metallic component, then it may be heated electro-inductively.  Prior to the final collection of the filaments, the different groups may receive different second coatings or finishes e.g. a size including, perhaps, lubricants such as petroleum or vegetable oils, molybdenum disulphide, or materials such as resorcinol formaldehyde latex which render the yarns &c., compatible with a material with which they are combined or the adhesive therefor. One or more single or composite applicators of coating materials, which may also effect the separation of filaments into groups, are positioned (perhaps in succession) at such a distance from the station where the filamentary streams originate that the temperature of the filaments thereat is commensurate with the particular coating methods and materials employed.

Abstract: 665,513. Feeding sheets. STAMMINGER, P. July 13 1949 [July 20, 1948], No. 18462/49. Class 100 (i). In a device for feeding sheets to a printing- machine the sheets 2 are each lifted from the top of a pile 1 by central suckers 3, 4 and carried thereby to feed-tapes 11, 12, 15, 16 on a feedtable 9, and inclined fixed guide plates 5, 6 are provided below the sheet at each side of the suckers to support the end portions of the sheet, the two lateral tape-conveying rollers 7, 8 being offset with respect to the central tape-conveying roller 10 to accommodate the guide plates.

Title: Improved electromagnetically controlled driving mechanism
IPC: H02K17/30
Filed: 1954-06-24
Abstract: 748,255. Dynamo-electric machines. SCHMID, W. K. June 24, 1954 [June 29, 1953], No. 18534/54. Class 35. An electric motor, or electromagnetic coupling or brake, is controlled by feeding it with current impulses whose duration may be modified to control the speed of the drive and whose intensity may be modified by means of a resistance to prevent jerky action. The regulated speed motor shown in Fig. 2 comprises a stator 1 driving a wound rotor 4 and carried on the rotor shaft 8 by means of a ball bearing, a further rotor 11 which serves to drive a friction disc 15 at substantially constant speed. A friction wheel 16 which engages the disc 15 is radially adjustable so that the speed of its shaft 28 may be controlled by a hand wheel 17. An insulating disc 32 (see Fig. 2a) is secured to motor shaft 8 and carries sets of contacts 40-46 engaged by fixed contacts 33, 34 of which contact 33 is adjustable towards the other contact to alter the duration of the current impulses under the control of hand wheel 17. The disc 32 also carries contacts 47-52 which are connected to contacts 40-46 and may be bridged by a sliding segment 31 driven round by the shaft 28 whose speed has been preset by handwheel 17. At starting, rotation of the disc 15 causes the segment 31 to move over to contacts 66, 67 by which the winding on the rotor 4 is short-circuited thus allowing it to start. If the motor is running at its preset speed, i.e. the speed of disc 32 is equal to the speed of shaft 28, the segment 31 bridges contacts 40-44 so that the short-circuit periods are of a certain duration, however if the speed rises or falls with respect to this speed more or less segments are covered which so modifies the duration of the impulses as to correct the speed variation. A variable resistance 62 controlled by a contact arm secured to a ratchet wheel 53 rotated by a pawl 63 on the segment arm 30 serves to control the current impulses when jerky motion of the segment rotates the ratchet. Extreme motion of the pawl causes it to engage a stop 65 which lifts the pawl. A modification is shown in which the resistance slider is controlled pneumatically or hydraulically. The invention may be applied to a motor with axially slidable conical rotor. It is described how the invention may be applied to an electromagnetic coupling or brake, two separate machines on a single shaft and in a single housing being used if desired. The current impulses may be magnified by passing through relays. Specifications 630,677 and 740,603 are referred to.

An open-celled foam rubber article is prepared by introducing into a solution of an unsaturated hydrocarbon polymer rubber in an inert organic solvent a curvative system for the rubber, foaming the solution and allowing it to cure at least until the foam is self-supporting, freezing the foam, removing the solvent therefrom, and completing the cure of the foam. The curative system may operate at room temperature. The preferred system is a mono- or multicyclic dimethyol phenol curative for the polymer and a Lewis acid or sulphonic acid. The preferred phenolic curative is a halogen-containing dimethyol phenol, e.g. a bromomethyl alkylated phenol formaldehyde resin. The preferred Lewis acid is anhydrous stannic chloride. The preferred amount of phenolic curative is from 1% to 20% by weight and the preferred amount of Lewis acid is from 0.1 % to 8% by weight, both based on the weight of the polymer. The preferred rubbers are an ethylone-propylene-diene terpolymer, cis-polybut adiene, balata and butyl rubber. The preferred foaming method is by application of gas under pressure to the solution so that it is absorbed and subsequent expansion of the pressurized cement into a space at lower pressure, the solution preferably being agitated in contact with the pressurized gas.
