Title: Apparatus for twisting two or more threads
IPC: D01H1/00
Filed: 1931-03-18
Abstract: 364,938. Twisting or doubling yarns. KARSCH, A., 39, Comeniusstrasse, Dresden, Germany. March 18, 1931, No. 8292. [Class 120 (ii).] In apparatus for twisting together, by means of a twist tube, two or more threads running from a cop or bobbin, an adjustable braking device is arranged directly above the cop and below the twist tube, the twist tube being rotated in the same direction as and faster than the cop, whereby a preliminary twist is imparted to the thread between the cop and the braking device, the twist being undone and the final twist in the opposite direction being imparted by the twist tube. The material may be moistened on its passage to the twist tube. The preliminary twist put into the yarn h between the revolving cop a and the adjustable yarn-braking device e is taken out by the twist tube b between the braking device e and the twist tube, so that the yarn is in an untwisted state somewhere between these two points, and whilst in this state it may be moistened in the water tube m. The yarn retains a permanent twist above the twist tube, passes through the drawing rollers c and is wound into a package. The bracket k carrying the guide d and the adjustable braking device e is vertically adjustable.

Title: Vehicle steering mechanisms
Inventor: BRIGGS WALTER HENRY
IPC: B62D3/12
Filed: 1966-02-25
Abstract: 1,104,205. Toothed gearing. BURMAN & SONS Ltd. 8 Feb., 1967 [25 Feb., 1966], No. 8366/66. Heading F2Q. In a vehicle steering mechanism comprising a rack 10 meshed by a pinion 11 on a steering shaft 12, collars 15, 16 are freely mounted on the shaft 12 on the side of the pinion 11 remote from the driver and wedging means acting between the collars 15, 16 are adapted to force the collars axially apart upon relative rotation between them in one direction and are adapted to permit the collars to move axially closer to each other upon relative rotation in the opposite direction. The collars 15, 16 are located between the end of pinion 11 and a further collar 21 secured to the shaft 12. The wedging means comprise a plurality of balls or rollers 17 located in coacting tapered grooves 18 formed in adjacent axial faces of the collars 15, 16. Friction pads 19, 20 are mounted in a housing 14 and are adapted to co-operate with the peripheries of collars 15, 16 respectively. When the driver turns shaft 12 in one direction or the other, the interaction between the rack 10 and pinion 11 will produce a small lateral displacement of the shaft sufficient to bring one of the collars 15, 16 into engagement with the associated pad 19, 20 thereby braking the collar and causing relative rotation between the collars 15, 16 in a direction to permit them to take up relative positions of minimum axial separation. If a force is transmitted to the shaft 12 from the road wheels of the vehicle, the opposite action occurs, and the collars 15, 16 are forced apart against the axial abutments to exert a resistance to movement of the shaft 12. An adjustable screw 22 engages the end of the shaft 12 in order to load the mechanism, and a torsion spring 23 interconnects the collars 15, 16 so as to tend to displace them towards the position of maximum separation.

The latter axis is identical with the diad axis of symmetry of the crystal. The X axis lies at an angle of 105¢ degrees to an axis perpendicular to the Y axis and in the major surface of normal growth. The Z axis completes the set of rectangular axes.

Title: Improvements in or relating to laminated magnetic structures
IPC: H02K1/14
Filed: 1948-03-25
Abstract: 646,528. Cores for dynamo-electric machines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. March 25, 1948, No. 8822. Convention date, March 29, 1947. [Class 35] The core of a small dynamo, e.g. cycle dynamo is composed of two or more superimposed laminations having a disc or annular form save for tongues which initially were approximately tangential to the lamination circumference but have been bent to form polepieces in planes which are edge-on to the lines of force of the magnetic field such that the edges of the inner and/or outer polepieces lie on a surface of a revolution. Figs. 1, 2 show plates 1, 2, 3 provided with tags 4, 6, 7 respectively, each of which extends more or less tangentially. The tags 4, 6, 7 are bent over dotted lines 5 so as to extend perpendicularly to the plane of Fig. 1, which results in the form shown in Fig. 2. The position of the lateral edges of the bent-over tags depends upon the endwise direction of the tags. With truly tangentiallydirected tags the lateral edges of the same side of the bent-over tags lie on the surface of an imaginary cylinder, whereas with tags, e.g. directed as those 17, the said edges would lie on the surface of a truncated cone. Fig. 6 shows a section of a hub dynamo having six rings 1-3 each pair of which is provided with a cylindrical part 23. Imbricated pole-pieces are formed by the bent-over tags 18, 26 projecting from righthand side and left-hand side rings respectively. An annular permanent magnet 27 with two annular plates 28 provided with alternate polepieces 29 surrounds the magnetic structure built from the plates 1, 2, 3.

Title: Improvements in or relating to the manufacture of shoes
IPC: A43B23/08
Filed: 1924-04-11
Abstract: 236,988. British United Shoe Machinery Co., Ltd., and Ricks, F. April 11, 1924. Stiffeners.-In order to render a stiffened shoe resistant to excessive heat, a thermoplastic stiffener is supplemented by a stiffening agent which is stiff at temperatures required to soften the thermoplastic stiffener and which requires to be softened by an agency other than heat. In the construction shown, a thermoplastic stiffener 8 is stitched to the edge of the vamp 3 between layers 6. 10 of swansdown or the like. A heatresistant stiffener 4, for example of fabric coated with water-soluble material of a gummy nature, is placed with its thinned edge between the overlapping portions of the toe cap 2 and vamp. The stiffeners are softened, the one by heat and the other by water before lasting. The stiffener 4 is preferably shorter than the stiffener 8 so that it does not extend over the shoe bottom after lasting. In a modification, a thermoplastic stiffener is coated on one or both sides with the heat-resistant stiffening agent. Such a stiffener may be softened by moist heat. Alternatively a thermoplastic stiffener may be dipped just prior to use in a heat-resistant stiffening agent, or may be used with an upper or lining coated with such an agent. In the latter case, an intermediate layer of lining material may be so coated. In another modification, the thinned edge of a thermoplastic stiffener is provided, particularly at the rear edge, with an extension margin of fabric impregnated with the heat resistant agent, so that the body of the stiffener derives its strength from a thermoplastic agent and the edge from an agent of a different character. In the assembly of a shoe, the heat-resistant element may be introduced into the shoe in a limp condition, and the thermoplastic-element stiff, and the shoe may then be placed in a heated press to soften and cement the thermoplastic element into the upper. Specifications 18174/13 and 210,161 are referred to.
