Title: Improvements in and relating to the production of shaped articles from organic thermoplastic materials
Inventor: KLIENE RONALD IAN
IPC: B29C41/02
Filed: 1963-10-15
Abstract: 1,058,586. Moulding hollow articles. IMPERIAL CHEMICAL INDUSTRIES Ltd. Oct. 5, 1964, No. 40645/63. Heading B5A. A box, crate, drum or like open-mouthed hollow article is moulded from an organic thermoplastic material by rotational casting in a mould, one surface of which has projections 4 into the mould cavity, the material being introduced into the cavity in such amounts that the walls of the moulding 6 become fused at 7 opposite the projections but are elsewhere separated by cavities. As shown, the mould is in the form of a pair of mould plates 1, 2 secured by clips 3. The articles may be formed in two or more parts which are subsequently joined together, for example by welding. For producing tubular bodies the mould is rotated about its longitudinal axis only, and for other articles the mould is rotated about two or more axes, for example two at right angles. The mould may be treated in an oven, by radiant heat or by electrical heaters in or around the mould walls, and cooled by water or cold air. A solid thermoplastic, e.g. polythene, polyproplene, unplasticized polyvinyl chloride and vinyl chloride/vinyl acetate polymer, may be introduced into the mould, heating the mould before and/or during its rotation. Alternatively a fluid polymer/plasticizer paste, e.g. polyvinyl chloride, is introduced into the mould, rotating the mould at a temperature below the paste setting temperature, and then heating the mould to gel the paste. The solid thermoplastic material is preferably powdered, granular or in other particulate form with a bulk density such as to fill the mould substantially completely. Preferably the bulk density of the material will be not exceeding 0.75 times the specific gravity of the thermoplastic material. In a preferred embodiment polythene with a melt flow index of 20 and specific gravity of 0.924 is cut into granules passing an 8-inch sieve and with a bulk density of 0.40 grams per c.c. fills a mould having a space between the plates of 0.25 and 0.5 inch. The mould is closed and then rotated about its longitudinal and transverse axes and while rotated it is heated for 10 minutes in an oven at 205‹ C. and then cooled in water. The finished panel had walls of 0.15 inch wide between ribs which were 0À6 inch wide at the wall joints.

The metal core may be degreased, etched and/or sand blasted, and heated to 100‹C before application of the bonding agent. The bonding agent which may be a polymer or a resin is applied as a solution in a volatile solvent.

Title: Electrolyte method of forming a coloured oxide film on the surface of aluminium or an aluminium alloy
IPC: C25D11/14
Filed: 1974-09-19
Abstract: 1486631 Colour-anodizing aluminium NIPPON LIGHT METAL CO Ltd and RIKEN LIGHT METAL INDUSTRY CO Ltd 19 Sept 1974 [21 Sept 1973] 40810/74 Heading C7B Al or an alloy thereof with or without an anodized oxide layer is coloured by electrolysis while connected as at least one electrode in a bath containing a colour-forming metal salt using a pulsating voltage of which the polarity is reversed at intervals longer than the single pulse period. The voltage may be half-wave rectified single-phase AC, optionally derived by phase control with an Si rectifier, or may be an essentially rectangular wave, e.g. derived from a commercial multi-phase AC. The positive and negative pulses may be symmetrical with a peak voltage Vp of 50-150V, a pulse duration of 2-500 mSec, a pulse period of 1-1000 mSec and a phase reversal frequency of 0À2-240 sec. Advantageously the decay time of charges stored in the cell from Vp to Vp is within 1/3h where h is the quiescent time between pulses, (h may be 18mSec) and this may be achieved by adding a parallel variable resistor in the circuit, e.g. from 10-500#. When multi-phase AC is used the pulse period may be based on the unit period of the AC. Treatment at 0À2-11 A/dm<SP>2</SP> is specified for 60 min to give a coating of 0À8-30Á thick. An acidic bath based on H 2 SO 4 , malonic, maleic, malic, oxalic, sulphosalicylic, sulphamic or tartaric acid is useful, containing such salts as Ag 2 SO 4 , AgNO 3  HAuCl 4 , Na 2 SeO 3 , CuSO 4 , SuSO 4 , NiSO 4  or CoSO 4 . Conventional cleaning treatments may be used, or the negative pulses may be used to achieve degreasing.

Title: Fabric material
IPC: D04H13/00
Filed: 1965-10-01
Abstract: The resilient firmness of fabric materials comprising a woven base fabric with filamentary fibres needled therein is improved by impregnating them with rubber or a synthetic elastomer, e.g. neoprene, nitrile rubber or a vinyl, silicone or urethane elastomer and then curing or gelling the rubber or synthetic elastomer.  Curing or gelling may be effected with calendering or pressing.  The base fabric may be woven from synthetic fibre yarns, e.g. polyester or nylon yarns, or natural fibre yarns, e.g. cotton or yarns blended from natural and synthetic fibres.  The fibres which are needled in may be natural or synthetic and during needling 500-2500 penetrations per square inch may be made, the base fabric preferably being supported under tension in the direction of the lengthwise yarns during needling.  If the woven base fabric contains synthetic yarns the fabric material may be stabilised by heating either before and/or after needling but prior to impregnation.  If the woven base fabric contains natural fibre yarns stabilisation may be effected by carrying out the needling step with the woven base fabric under substantial tension.  Impregnation may be effected by immersion or by applying a layer of latex to the fabric material and causing it to be absorbed with or without heat and/or pressure.  The impregnated materials may be coated with rubber or a synthetic elastomer after drying and prior to curing or gelling.  The materials may be used for conveyor belts or in gaskets, diaphragms, bushings or washers.ALSO:The resilient firmness of fabric materials comprising a woven base fabric with filamentary fibres needled therein is improved by impregnating them with rubber or a synthetic elastomer, e.g. neoprene, nitrile rubber or a vinyl, silicone or urethane elastomer, drying, coating them with rubber or a synthetic elastomer and then curing or gelling the rubber or synthetic elastomer.
