Title: Improvements in or relating to the manufacture of composite artificial filaments
IPC: D01D5/32
Filed: 1944-02-29
Abstract: Crimped composite artificial filaments are obtained by forming composite filaments having at least two eccentrically arranged components of different shrinkage characteristics, stretching the filaments beyond the elastic limit of at least one of the components, relaxing the filaments while in an at least partially softened condition obtained by softening before, during or after stretching, and bringing the filaments into unsoftened condition while retaining them in relaxed condition.  The composite filaments may be obtained by extruding two or more different spinning compositions through adjacent orifices or extruding them in separate or only partially intermingled phases through a common orifice or a plurality thereof into a gaseous or liquid setting medium as described in Specification 579,081, and the setting medium may function by either a cooling, precipitating or evaporative effect.  Any filament-forming materials or solutions which differ in composition, origin or characteristics such as differing solutions of viscose, proteins such as casein or soya bean protein, cellulose derivatives such as cellulose acetate or ethyl cellulose, and resins such as nylon, vinyl resins such as the copolymers of vinyl chloride and vinyl acetate and the vinylidene halides, may be employed.  Alternatively, two or more materials of different classes may be combined such as a protein with a viscose, a protein with a cellulose acetate or a cellulose acetate with a vinyl resin.  One or more of the filament components is softened with, e.g. hot or cold water, or heat or swelling agents, before or after stretching, and the stretched filaments are cooled or dried in a relaxed state to set the crimp. If two thermoplastic components having different shrinkage characteristics at a given temperature are combined, the after-stretched composite filaments may be crimped by subjecting them in relaxed condition to the given temperature. Stretching may be effected on the composite filaments as they come from any stage of the liquid after-treatment process to which they are usually subjected, and when a stretch is applied to the filaments during their production, the amount of after-stretch is reduced accordingly.

Title: Improved joining means for pre-formed walls
IPC: E04C2/04
Filed: 1945-02-15
Abstract: 588,393. Walls. EVENNETT, F. F. Feb. 15, 1945, No. 3758. [Class 20 (iv)] In joining means for two walls, one wall is formed with an extension which has a greater dimension at its extremity than at its root and a hole or recess is formed in an adjoining or abutting wall, which recess is smaller at its mouth than at its root and large enough at its small end to permit of the free insertion therein of the larger end of the extension. As shown in Fig. 3, a wall A is formed with a recess into which is inserted an extension on the wall B, with a wedge W holding the walls together. The recess and extension may be formed as dovetail slots and tenons or have one or more straight sides. Where the recess is formed as a blind hole as in Fig. 5, the adjoining wall F is formed with a recess above the extension thereon to enable the wedge W to be driven in from the inside. Two or more walls may be joined together, e.g., as shown in Fig. 16, two adjoining walls M and N are formed one with an extension and the other a recess and each is formed with half of a recess for engagement by an extension on a third wall P abutting them at right angles. A wall of storey-height would be provided with more than one joining extension or recess.

Abstract: 564,766. Temperature - responsive actuating elements. WILCOLATOR CO. March 17, 1943, No. 4336. Convention date, July 31, 1942. [Class 64 (ii)] [Also in Groups XXIX and XXXVII] To obtain a snap action on rise or fall in temperature for operating a switch or valve, a strip 21, which may be of metal, with a permanent curvature across its length, is held as between end brackets 28, 34 under compression such that it buckles to be curved along its length. On rise in temperature, the mounting of the end supports, shown as a channel member 22, expands and the strip snaps into contact, for example, with a contact 50 adjustably mounted above the strip. ' Grooves 21a in the strip accentuate the action. By using highexpansion metal for the support 22 and low expansion metal for the strip 21, an ordinary thermally acting switch is obtained. If metal of similar expansibility is used for both, then the apparatus would function as a fire alarm, owing to the casing receiving the heat first. In a modification, Fig. 9, to enable the parts of the device to be free from carrying current, the contact 86 and a co-operating contact 89 are both insulated, the latter being supported by a springy strip 90 which normally keeps the insulated back 94 of the contact in contact with the actuating strip 81. U.S.A. Specification 2,253,552 is referred to.
