Title: Method of making a moulded article
IPC: B29C67/00
Filed: 1975-11-21
Abstract: 1519520 Compression moulding extruded working material FURUKAWA ELECTRIC CO Ltd 21 Nov 1975 [21 Nov 1974 (2)] 47923/75 Heading B5A An article having a minimal amount of residual stress is made by compression moulding a rodlike extrudate having a diameter of at least 15 mm. in a metal mould having a grooved surface. Preferably the extrudate has a diameter of at least 50 mm. and is at a temperature of at least 180‹ C. after extrusion. Compression is preferably effected under 5-100 kg./cm.<SP>2</SP> for times between 1 and 20 minutes and in a mould having grooves with a depth and width of between 5 and 10 mm. and a temperature of 10-80‹ C. Preferably the grooves of the mould spaced 200-300 mm. at the most from each other. The process is useful in utilizing scrap thermoplastic material, either on its own or with virgin material to form articles between 5 and 15 mm. thick such as flanges for cable reels or pallets. The extrudate may comprise a core covered by a sheath to give a skinned article and may contain a fibrous or metallic reinforcing agent. A foaming agent, to give a light weight article, may also be included. Typical working materials are polyethylene, cross-linked and non-cross-linked, and polypropylene and the metallic reinforcement may be included by using a diced metal covered strip as the working material. In a first example, a flange for an electric wire reel was made by extruding a rod of waste polyethylene, coiling the rod in a lower metal mould plate furnished with annular and radial grooves 2, and compression moulding using an upper metal mould formed with grooves 4. In a second example such a flange with a metal reinforced core was made using a core rod derived from a diced aluminium coated polythene sheet and a sheath of waste polyethylene. In a third example a flange was compression moulded from an extrudate comprising a core of crosslinked low density polythene and a sheath of non-cross-linked low density polythene.

Patent GB-483427-A (GB)
Abstract: 483,427. Directive wireless signalling. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENTFABRIEKEN. May 11, 1937, No. 13419. Convention date, May 14, 1936. [Class 40 (v)] In a visual indicator for directive reception of a dot-dash radio beacon system, the audiofrequency signals after transformation into impulse combinations, are applied to the. control grids of a pair of push-pull valves, the common anode circuit of which is arranged to bias the valves to cut-off at the first impulse, the sign of which indicates direction. Audiofrequency signals from the output of a receiver are supplied to terminals K3, K4, and are rectified, and then amplified in the valve V1. Voltage impulses are produced in the secondary of transformer T2, the initial sign of which is dependent upon whether the signal is a dot or dash, and are fed to the push-pull valves V2, V3 in whose anode circuit are connected the meter M and potentiometer ACB. The valves V2, V3 are biassed so near cut-off that when a signal is applied the total anode current increases and condenser C2 is charged through the rectifier G by the potential drop across a resistance R9. The condenser C2 discharges through resistances RIO, R11 and biasses the valves to cut-off. The time constants are so arranged that the circuit only responds to the first impulse produced by a dot or dash, so that the deflection of the meter indicates deviation. Specification 463,694 is referred to. The Specification as open to inspection under Sect. 91 describes an arrangement Fig. 1 (Cancelled) for deriving the required dot-dash off course signals from an ordinary transmitter. The outputs from the frame aerial R and the non-directional aerial are combined in series and supplied via terminals K1, K2 to the input of the circuit of Fig. 1. The polarity of the voltage of transformer secondary S3 is periodically reversed by operation of switch 2 which causes rectifier W or W2 to be in the conductive condition. Switches 1 and 2 are operated by relay Rl which closes when the condenser C1 has charged to a certain voltage through resistance R8, the condenser then discharging relatively rapidly through resistance R7. In this way the time intervals during which the relay is energized' and de-energized, causing the aerial outputs to be added in like or opposite phase, differ in length according to the difference in duration between dashes and dots. This subjectmatter does not appear in the Specification. as accepted.
