Abstract: 1308287 Amplifier gain control SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 9 Nov 1971 [12 May 1971] 52019/71 Headings H3T and H4R A controlled amplitude sound-frequency signal Vu having a similar form and frequency to an input signal Vi is derived therefrom by filtering at E a pulse-width modulated signal Vc, obtained by comparing at D the input Vi and a triangular wave Vt formed at C from a square wave generated at A and fed through an amplifier B, whose gain is controlled by the D.C. level resulting from peak-rectifying the input Vi at F. The pulse-width modulated output Vc from D, which may be a Schmidt trigger, has its high value when Vt exceeds Vi (Fig. 3, not shown) and vice versa; and when Vi increases so that the pulse widths tend to change, the triangular wave also increases to offset the pulse width change and so reduce changes in output amplitude. The peak rectifier F is transistorized (Fig. 4, not shown) and includes a variable resistor to set the time constant thereof. The amplifier G includes a transistor and Zener diode arranged to prevent the output falling below a minimum level, so as to determine the point (S, Fig. 1, not shown) at which the amplitude control becomes effective. Compression and expansion is mentioned.

Abstract: 1,144,777. Embossing. DUNLOP SEMTAX Ltd. 1 Dec., 1966 [16 Dec., 1965], No. 53541/65. Heading B6J. Embossed effects are obtained on the surface of an expanded thermoplastic resinous composition by subjecting a selected portion of the surface of an expansible resinous composition to treatment to render it less thermoplastic and expanding the composition whereby untreated portions of the surface rise above the level of the treated portions. The treatment preferably comprises applying to the surface a cross linkable substance and a cross linking agent. Alternatively cross linking of the cross linkable substance may be by heat or radiation. Suitable cross linkable substances are unsaturated esters e.g. allyl methacrylate, diallyl fumarate, triethylene glycol dimethacrylate, ethylene glycol dimethacrylate, tetraethylene glycol dimethacrylate 1, 3-butylene glycol dimethacrylate, polyethylene glycol dimethacrylate, trimethylol propane trimethacrylate, tetrahydrofurfuryl methacrylate and cyclohexyl methacrylate. Cross linking agents specified are tertiary butyl perbenzoate and methylethylketone peroxide. The treatment of selected portions of the surface may be by printing with a conventional ink comprising a thermoplastic polymer or copolymer, e.g. vinyl chloride vinyl acetate copolymer, a pigment and a plasticizer (e.g. a phthalate ester plasticizer) a part or all of which plasticizer has been replaced with a polyfunctional ester listed above, the whole preferably being carried by a suitable liquid medium e.g. cyclohexanone, methyl ethyl ketone, or tetrahydrofuran. Methyl isobutyl ketone and xylene may also be present. A cross linking agent (as listed above) may also be present. The thermoplastic resinous composition to be treated may be polyvinyl chloride or a vinyl copolymer together with a plasticizer, e.g. dioctyl; phthalate, a blowing agent, e.g. azodicarbonamide, a stabilizer e.g. a mixture of cadmium and zinc.soaps, and pigments. Colouring material may also be applied to the surface of the resinous composition before or after or concurrently with the treatment to provide the less thermoplastic portions. After application of the printing ink or other colouring material a sealing agent, e.g. clear P.V.C. paste or a solution of P.V.C. may be applied. The sealing agent may be applied after expansion of the resin and may in this .case be a cross linking agent, e.g. polyurethane or an unsaturated ester (as listed above).

Filed: 1966-12-17
Abstract: 1,155,120. Producing yarns by film fibrillation. CIGARETTE COMPONENTS Ltd. 7 Dec., 1967 [17 Dec., 1966], No. 56579/66. Heading B5B. Yarn is produced from a narrow elongate film strip of synthetic organic thermoplastic material having a cross-sectional area which is appropriate to the desired denier of the yarn, the film strip having been oriented longitudinally by stretching it to strengthen it in the longitudinal direction and weaken it in the transverse direction. Alternatively the film strip may have been slit from a supply reel of film which has been so stretched. The stretched film strip is then passed through a rotative or a non-rotative false twist inducing member without passing around any member extending across the passage of the yarn therein, so that the film strip is caused to split along lines parallel with the longitudinal direction. The false twisting may be carried out first in one sense and then in the opposite sense. After false twisting the yarn may be given a true twist. The film strips may consist of a stereoregular polypropylene or a copolymer of styrene and propylene. The film strips may be stretched in air at an elevated temperature, preferably between 140‹ and 100‹ C., and the stretch ratio used may be between 7: 1 and 13: 1. After stretching, the film may be heat-set at a lower temperature in a relaxed condition. In an example, a polypropylene film 277 mm. wide and 0À046 mm. thick is slit longitudinally into strips 7 mm. wide, stretched at a stretch ratio of 9:1 at a temperature of 150‹ C., passed under minimal tension into an oven at 120‹ C. at a speed of 100 meters/minute and the stretched film strips which now have a thickness of 0À015 mm. are wound up on centre cores. These are placed in an oven at 135‹ C. for two hours, thereafter brought to a woollen yarn ring spinning frame, and the film strips are withdrawn from the centre cores at 20 metres/minute and passed through two counter rotating false twist tubes revolving at 2200 r.p.m. The yarns thereby formed are wound on to ring spindles and twisted. The false and true twisting treatments of the longitudinally oriented film strips may be effected upon a condenser yarn ring spinning frame, for example, a woollen yarn ring spinning frame.
