Patent GB-408729-A (GB)
Title: Improvements in or relating to a process for the manufacture of rubber products
Filed: 1932-11-18
Abstract: Porous or microporous rubber products are produced by converting a rubber dispersion into a gel by the addition of a hydrolysable ester of an acid, which if added in sufficient quantity in the free state would cause coagulation, and vulcanizing the gel under such conditions as to prevent evaporation of the liquid in the pores. Preferably the amount of ester added is not sufficient to cause gelling until the dispersion is heated, as for example in a mould or by a heated die.  A preferred ester is triacetin.  An example is given.  When the mixture is extruded through a heated die, a soap, e.g. ammonium oleate, is preferably added.  When battery separators are being made, strengthening ribs may be provided by pressing the moulded gel along the desired lines to provide ribs of compact non-porous rubber.

Title: Thermoplastic film production
Inventor: SANDIFORD DENIS JAMES HENRY
IPC: B29C48/08
Filed: 1965-07-30
Abstract: 1,129,136. Films. IMPERIAL CHEMCIAL INDUSTRIES Ltd. 5 July, 1966 [30 July, 1965; 24 Jan., 1966], Nos. 32703/65 and 3101/66. Heading B5B. In a process for quenching a molten thermoplastic film which has been freshly extruded on to a moving casting surface and wherein an electrostatic charge is deposited on the upper surface of the cast film from an electrode situated near the film surface, and maintained at a large electrostatic potential difference from the casting surface such that the film is caused to adhere thereto, means are applied to maintain the electrode substantially free from deposits arising from condensation of vapours of volatile matter in the thermoplastic material, or from the decomposition products of such volatile matter. When the electrode is a wire, such means may take the form of (a) a scraper plate having an orifice just sufficient to allow passage of the clean wire, (b), a bath containing a solvent for the deposit, or (c) a method of reducing the contaminant concentration in the vicinity of the electrode. In the case of (a) or (b) the scraper or bath may be passed periodically along the wire, or a continuous electrode wire may be used, which is continuously moved through the scraper or bath. In case (c) an air blower or vacuum device may be used to remove the volatiles from the electrode vicinity. Another method of performing the invention consists in unwinding a clean wire from a reel at one side of the die orifice and winding the slightly contaminated wire on a reel on the other side, at such a speed that the wire accummulates substantially no deposit. Suitable thermoplastics are polyolefine polymers and copolymers polyethyleneterephthalate, polyamides, PVC, polyoxymethylene or poly -3,3-bischloromethyl oxacyclobutane. Volatile materials are U-V and heat stabilizers, and antistatic agents, Polypropylene, containing 2-hydroxy-4-methoxy benzophenone is exemplified.
