Patent GB-1063772-A (GB)
Title: Synthetic strand and method of manufacture
IPC: B29D7/00
Filed: 1964-02-10
Abstract: A synthetic strand useful as, or for making, ropes, twines, cords, or strings, comprises a twisted, elongated film of synthetic, polymeric material having a high degree of molecular orientation so as to provide a large number of lines of potential or incipient cleavage in a direction parallel to the longitudinal edges of the film and slit, parallel to said edges, along some but not all of said lines of potential or incipient cleavage.  A film is cut to the desired width, drawn 8-20 times to fully orient it and passed into a gas jet so that the turbulence of the gas causes the film to slit along some of its lines of potential cleavage. p  The jet may have a slot or circular-shaped film opening.  The slit film is then twisted-e.g. on a ring spindle-and/or combined with other slit films which are twisted together and heat set.  The film may be formed of a crystalline polyethylene, polypropylene-which may contain a black pigment for ultraviolet degradation resistance and an autioxidant for heat resistance-or polyallomer.

Title: Improvements in coating process and product
IPC: D21H19/58
Filed: 1963-02-14
Abstract: A fibrous, cellulosic paper substrate having a visually continuous, microporous, print-receptive coating (comprising a major weight proportion of a finely divided solid filler and a minor proportion of at least partly coalesced non-water-absorptive, film-forming, heat-softenable resin particles which bond the filler particles into a film and secure the film to the substrate) is produced by forming a layer of the coating material on the substrate, e.g. by depositing an aqueous suspension of the filler and resin particles thereon and allowing the water to drain off or into the substrate, and passing the substrate with the coating material through the nip of a pair of turning rolls, at least that roll contacting the coated side being a heated finishing roll e.g. of smooth chromium, whilst at least that part of the substrate adjacent to the coating layer is sufficiently wet with water to be permanently pressure-deformable, thereby to cause the resin particles at least partly to coalesce to form the completed coating.  Specified resins are polyvinylidene chloride, P.V.C., P.V.A., copolymers of vinyl chloride, vinylidene chloride and polyethylene, copolymers of alkyl esters of acrylic and methacrylic acids with one or more monomers such as acrylic acid, methacrylic acid, vinyl acetate and vinyl chloride.  Up to 50% by weight of rubbery non-water-absorptive polymers e.g. styrene/butadiene and acrylonitrile/butadiene (with or without styrene) copolymers. Specified fillers are clay, CaCO3, TiO2 and ZnO. Optionally, the coating may also comprise a lubricant (which lubricates the finishing surface) e.g. a high-melting sugarcane, paraffin or oxidised hydrocarbon wax and conventional additions e.g. dyes, plasticizers, viscosity regulators and dispersants. Processes are described in which the coating material is applied during the paper-making operation, the stock is dried and rewetted before the final finishing step and wherein the coating is applied as an aqueous dispersion and only partially dried immediately before the finishing step.

Title: Improvements in and relating to combined television and sound receiver circuits
IPC: H04N5/62
Filed: 1948-02-27
Abstract: 663,167 Multiplex systems. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 27 1948 [June 14, 1946], No. 6120/48. Class 40(v)' A picture signal carrier modulated in amplitude, and an audio signal carrier of different frequency modulated in frequency, are received in a common receiver and passed through a common channel, at the output of which they are mixed in a rectifier or like device to produce both the television signal and an audio-modulated sub-carrier of the difference frequency. Such a system is described in Specification 639,926. According to the present invention, in order that the audio signal may still be produced if the television carrier is not received, a local source of oscillations is started up when such failure occurs. As shown in Fig. 2, the two carriers, which may be 4.5 mc. apart in the 40-50 mc. range, are received on the aerial 1, reduced in frequency by heterodyning at the stage 2, and amplified at the I.F. stage 4. The two LF. waves are then fed to a detector 39, the output of which includes the detected picture signal and a 4.5 mc. sub-carrier modulated by the audio signal. This mixture is amplified at 42 and fed to a separating filter 7, Fig. 2 (not shown), which passes the picture signals to the amplifier 8 and reproducer 44, and diverts the higherfrequency sub-carrier through a limiter 10, discriminator 11, and audio amplifier 13 to a loud-speaker 14. Should the picture signal fail, a local oscillator 47 starts up and feeds a wave to the coil 40 and detector 39 equal in frequency to the picture I.F. Reception of the picture signal creates a negative inhibiting voltage at the grid of the oscillator 47 owing to the action of the rectifier 45 of the D.C. restorer circuit 45, 46. The oscillator 47 may alternatively be controlled by an anode supply switch 52. In a further modification, the local oscillator control voltage is derived by a rectifier connected to a circuit coupled to the coil 40 and tuned to the picture I.F. Fig. 3 (not shown).

Abstract: 540,252. Barium and lead sulphates. RENWICK, F. F., and TASKER, H. S. April 9, 1940, No. 6430. [Class 1 (iii)] [Also in Groups XL and XX] As an intensifier in X- or gamma ray photography a solid solution of the crystals of barium sulphate and lead sulphate is used either in the form of a layer separate from the silver halide emulsion or mixed therewith. The sulphates should be substantially pure and free from iron, manganese, chromium, copper, nickel, cobalt, silver, arsenic, antimony and silica. From 1 to 40 per cent. of the lead sulphate may be used in the solution, to which calcium and/or strontium sulphate may be added. The mixture is fired at 'a temperature between 600‹C. and 1150‹C.; it may be done in the presence of a flux such as sodium or magnesium sulphate which is subsequently dissolved out. The sulphates may be produced by double decomposition from solutions of barium and lead nitrates and sulphuric acid or soluble sulphates separately the resulting sulphates after drying being mixed, ground, and fired, or the two sulphates may be prepared from a single solution. In another method barium chloride and lead nitrate in solution are added to sodium sulphate dissolved in weak hydrochloric acid. The intensification effect depends on the proportion of lead sulphate in the mixture and on the temperature and length of fixing. In determining the intensification factor a layer of 20 grams per square decimetre is employed. In use the fluorescent layer may be used on a separate support or the sulphates may be dispersed through the silver halide emulsion. In other arrangements the sulphates are dispersed in a colloid carrier which may be used as a layer in front of or behind the emulsion or in the support. The sulphate layer may be dissolved away or stripped off before development of the emulsion. Two emulsion layers one on each side of the support may be used.
