Title: Production of composite textile materials
IPC: D04H13/00
Filed: 1972-07-14
Abstract: 1392373 Laminates OBERLAUSITZER TEXTILBETRIEBE VEB 14 July 1972 33063/72 Heading B5N [Also in Division D1] A composite textile material is produced by stitching a layer consisting of threads or fibres of a fibre fleece which extend substantially transversely in relation to the longitudinal direction of the layer, on to a previously manufactured base layer, e.g. a woven or knitted fabric or fibre sheet, by means of longitudinally extending parallel chain stitch seams using a single- or multi-thread stitching material consisting of fibre material components of which at least one has a lower softening range than the other fibre component or components used, and subjecting the composite material so produced to a heat treatment in which only the fibre component with the lower softening range is rendered heatsealable and adheres to the fibres or threads in contact with it. Stitching materials comprising two-component fibre materials of the side-onside, core-sheath or matrix fibril types may be used. The stitching material may comprise a mixture of polypropylene and polyester fibres, a mixture of fibres of vinyl chloride/vinyl acetate or vinylidene chloride copolymer and viscose rayon, cotton or polyester fibres or a mixture of polyethylene terephthalate or polyamide and polyolefin fibres. Heat shrinkable threads and texturized filaments may also be used. Heating may be effected with infra-red radiation or hot air. Pile fabrics may be produced by cutting the fibre layer between the joining seams.

Title: Improvements in processes for hardening copper and copper alloys
IPC: C22F1/08
Filed: 1936-12-02
Abstract: In a process for hardening copper and copper alloys, the metal is first chilled to about the freezing point of water, heated out of contact with the atmosphere in a liquid batch, such as beef tallow, to a temperature slightly above the boiling point of water, e.g. 240 DEG  F., immersed in a hot cleansing solution, dried and cooled.  The process may be repeated until the desired hardness is obtained, the chilling temperature then being 10 DEG  F. below zero, and the temperature of the heating bath being raised 40 DEG  F. for each subsequent treatment, the upper limit of the temperature of the bath not exceeding 400 DEG  F.  Instead of beef tallow, other oils such as mineral oils, petroleum jelly, vegetable oils or other animal fats may be used and soap solution may be used as the cleansing solution. The treatment of a copper alloy containing 60,81 per cent of copper, 35.85 of zinc, 2,93 of lead and 0,24 of tin is described.

Abstract: 1,019,280. Endless conveyers. M. VON BUSHE, and T. ALTENBRACHT, [trading as TH. KIESERLING & ALBRECHT]. Aug. 17, 1964 [Sept. 25, 1963], No. 33617/64. Heading B8A. Pipes 2 pass from an hydraulic testing press 1 to claws 7 on four laterally spaced endless conveyer chains 8a-8d (8a only visible in Fig. 2). Each of the latter has the same number of links but the link lengths vary in order that the overall lengths of the chains may be different (Fig. 3, not shown). The chains are thus guided by respective channel members 15 (Fig. 4, not shown) which determine the chain paths. The pipes are thus brought into a position in which they are inclined to the horizontal. This effects drainage of testing water. The inclination of the pipes is assisted by the action of magnets 18 carried by chains 17, 18, driven in synchronism with the chains 8a-8d.

Abstract: 615,219. Air compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and DAVIDSON, 1. M. Dec. 13, 1945, No. 33836. Drawings to Specification. [Class 110 (i)] In an axial or radial flow bladed compressor the gas enters the rotor with supersonic velocity relative to the rotor blades causing a compression shock system which rotates with the rotor. The leading edge of each blade has its trailing surface substantially in the line of the relative velocity and its leading surface at an angle sufficient to set up a shock system, but not so great as to cause the shock waves to form up-stream in the stator passages. Preferably, the gas velocity relative to the stator blades and that relative to the rotor blades at outlet are sub-sonic. The blades may have a bi-convex profile. A stage according to the invention may be compounded with ordinary stages, and, with oppositely-running rotors. There may be more than one stage according to the invention. Reference has been directed by the Comptroller to Specification 622,049.

[Classes 39 (i) and 40 (v)] In devices with the current to an anode controlled by trans verse deflection of the electron stream as ir the parent Specification, the cathode rays are made parallel without an intersection, before they reach a diaphragm aperture which is electron-op tically reproduced ir the plane of the anode A slit 5<1> in a dia phragm 5 is reproduced in the plane of the anodes 10, 11 by the field 21 between boxshaped electrodes 8, 9, placed beyond the deflecting plates 6, 7. Rays from the cathode 1 are made parallel before reaching the slit 5<1> by a preliminary concentrating system of two box-shaped electrodes 2, 4 and a diaphragm 3. The electrodes are biassed as shown, and the electrodes 2, 4 are at low potential, preferably connected to the cathode 1. The anodes 10, 11 as well as the electrode 8, may be earthed if the electrode 9 is long to screen the anodes from the field 21, or if a net 9<a>, preferably of coarse mesh and connected to the electrode 9 is placed in front of the anodes. The control potentials 14 are applied to one deflecting plate 6 and a reversed-phase output is obtained from the resistance 19 in the circuit of the anode 10. Increased amplification may be produced by coupling the anode 10 to the other deflecting-plate 7 through a condenser 18 and potentiometer 15 as shown. The degree of back coupling may be so great that the ray has only two stable positions and is thrown from one to the other when the potential 14 exceeds a certain value, a relay dependent on a threshold value being thus obtained. The ray is statically screened by the electrodes. Dimensions and voltages are specified. The Specification as open to inspection under Sect. 91 comprises also anodes with bent outer edges and the circuits described in Specification 451,021. This subject-matter does not appear in the Specification as accepted.
