Abstract: 941,493. Polyester filaments. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 22, 1962 [Jan. 30, 1961], No. 3439/61. Drawings to Specification. Heading B5B. [Also in Division C3] Melt-spun filaments are made from polyesters of aromatic dicarboxylic acids containing not more than 0.5% of an organopolysiloxane fluid, e.g. 0.05-0.2% of dimethylpolysiloxane. Organopolysiloxanes used may contain alkyl, aryl, substituted alkyl, substituted aryl, alkaryl, aralkyl, or alkenyl groups, examples including methyl, octyl, phenyl, γ-trifluoro-propyl, γ- cyanopropyl, tetrachlorophenyl, vinyl and alkyl groups, and preferably should not contain any silicon-bonded hydrogen atoms. Organopolysiloxane fluids used may be entirely linear or up to about 10% of the silicon atoms may be crosslinked. They may also be end-stopped if desired, e.g. with trimethylsilyl groups. The polyester may be one derived from terephthalic acid, especially polyethylene terephthalate, polyesters of ethylene glycol with a mixture of terephthalic/5 (sodium sulpho) isophthalic acids, with a mixture of terephthalic and isophthalic acids, or with a mixture of terephthalic and another dibasic acid, e.g. sebacic or adipic acid, or a hydroxy carboxylic acid, e.g. p-hydroxybenzoic acid. Polyesters of terephthalic acid with a glycol other than ethylene glycol, e.g. 1: 4-bis-(hydroxymethyl) cyclohexane may also be used. Filaments so made have a greatly reduced tendency to break during spinning.

Title: Improvements in or relating to control systems for direct current electric motors
IPC: H02P7/292
Filed: 1948-02-11
Abstract: 643,771. Automatic speed control systems. GENERAL ELECTRIC CO., Ltd., and DALE, S. H. Feb. 11, 1948, No. 4044. [Class 38 (iv)] [Also in Group XXXVII] A speed control circuit for a D.C. motor supplied by grid controlled rectifiers, includes a non-linear thermionic amplifier which compensates for the non-linearity of the speed/loadcurrent characteristic of the motor. Transformer 8 and rectifiers 3 and 4, connected for full-wave rectification, supply a shunt or separately excited D.C. motor 1. The D.C. voltage is, controlled by the rectifier grids being connected to a phase shifting network 15 which includes a saturable reactor 16 controlled by a triode 17 directly coupled to a second triode 26. The grid-cathode voltage of this valve is the resultant of the rectifier output voltage, an adjustable reference voltage tapped off a battery 23, and a voltage appearing across resistor 21. This voltage increases non-linearly with increase in motor load current since a voltage proportional to motor current is obtained either from current transformer connected in the anode circuits of the rectifiers, or from a device 30 which comprises a pair of saturable reactors controlling an A.C. supply according to the D.C. load current, and applied in opposition to a reference source 29 to the control grid of a, variable-mu tetrode 28 which is operated over a suitably curved portion of the Ia/Vg characteristic. Thus the rectifier output rises with increase in load current and compensates for the non-linear drooping speed/ load-current characteristic of the motor. Specification 663,772 is referred to.

Title: Improvements in or relating to bonded fibrous sheet material
IPC: D04H1/48
Filed: 1959-02-05
Abstract: 915,682. Bonded fibre fabrics; laminates. MOBGENSTERN, D. Feb. 5, 1959 [Aug. 4. 1958], No. 4135/59. Class 140. A needled fabric is characterized by having at least one layer of adhesively-bonded fibres interiorly thereof and individual fibres extending from one side of the said layer to the other side through needle perforations in the said layer. The fabric may be made by forming a fleece of fibres, coating a surface thereof with an adhesive binder to form a thin layer of bonded fibres, drying the said surface and then needling the unbonded fibre fleece through the layer of dried adhesive binder. A single needling operation on each side may be carried out. Specified fibres are cattle hair, horse hair, wool, cotton, linen, palma, cocoa, asbestos, glass, metal, rayon, acetate, nylon. Specified binders are natural or synthetic rubber, vinyl resins, isocyanate resins, polyamides, polyacrylates. The fleece may be formed by airdeposition, carding or garnetting. The binder may be applied by spraying. As shown (Fig. 1), a fibre fleece 7 has one surface 6 spray coated with binder and dried. Fig. 2 shows the same fleece after needling, whereby individual fibres 8 have been forced through the bonded layer 6 causing them to protrude on the upper side of layer 6 and in effect form a new outermost surface layer 9 binding the existence of adhesive bonded layer 6 from visual discernment. Both surfaces of the fleece may be coated before needling. In Fig. 4 two layers of fleece 17, 17<SP>1</SP>, each having an adhesive coated outer layer 6, 6<SP>1</SP> are placed with the latter layers face to face, dried to set the adhesive and then needled in both directions whereby fibres 8 from layer 17 are forced into layer 17<SP>1</SP> and fibres 8 from layer 17<SP>1</SP> are forced into layer 17, thereby thoroughly interlocking the layers into an integral needled fabric. The outer surfaces of the combined layers may be lightly coated with adhesive to bind loose fibres. Examples disclose the carrying out of the invention with fleeces of cotton, nylon, wool, wool and nylon, cotton and nylon, acetate and nylon fibres; and with binders consisting of polyvinyl chloride, acrylic resin and casein, nitrile rubber, polyamide resin, nitrile rubber and melamine formaldehyde polytmethane compound.
