Patent GB-2020699-A (GB)
Title: Electroplating a hollow laminated body
IPC: C25D7/04
Filed: 1979-05-09
Abstract: A hollow laminated body e.g. a container or a pipe comprises a base body 1 consisting of fibres in a hardenable plastics matrix, with a metal surface layer 2 which in the illustrated case is the interior of the body, but could be the exterior thereof. To facilitate application of the metal layer 2, and to ensure secure anchorage thereof to the body 1, carbon fibres are used as the fibres in the body 1 and the metal layer 2 is a galvanic coating. In producing the hollow laminated body, the surface to be coated, of the base body 11 is treated before the galvanic coating step, either by exposing the carbon fibres at said surface or by applying a conductive medium, such as a conductive lacquer, thereto. <IMAGE>

Title: Condensation method and apparatus
IPC: F28B3/04
Filed: 1981-05-22
Abstract: A storage tank 2, containing a volatile liquid such as petrol, has a vapour recovery pipeline 32 with a valve 34 in it. The pipeline 32 terminates at the top of a condenser 38 fitted with a spray head 40 for spraying liquid nitrogen into the condenser 38. The flow of liquid nitrogen to the spray head 40 is controlled by valve 44 which opens upon the pressure in the ullage space 6 of the vessel 2, as sensed by pressure sensor 30, reaching a first chosen value. Thus, the condenser is pre-cooled. On the pressure in the ullage space 6 reaching a second value, higher than the first valve 34 opens and vapour flows through the pipeline 32 into the condenser 38 where it is condensed by the liquid nitrogen. The resulting condensate is returned to the tank 2 via a phase separator 52. <IMAGE>

Title: Method of exfoliating coating of coated optical fiber and exfoliating tool therefor
IPC: G02B6/245
Filed: 1982-03-24
Abstract: A method of exfoliating the coating of a coated optical fiber, which method has the steps of producing a longitudinal crack in the coating layer of the optical fiber cleaving the coating into a plurality of cleaved strip pieces while longitudinally growing the crack, and then outwardly bending off the strip pieces. The exfoliating tool is constructed to conveniently cleave the coating layer of the optical fiber and to cut the cleaved strip pieces. Thus, it does not damage the optical fiber upon exfoliating of the coating layer from the coated optical fiber, and can efficiently exfoliate the coating of the optical fiber. The tool may take the form of a sleeve or ring having knife edges, or a pair of split pieces 6', 6'' mounted at the end of grips 11', 11''. <IMAGE>

Title: Cutting machines
IPC: B23B29/034
Filed: 1982-04-28
Abstract: A spindle assembly (8) for a cutting machine comprises a spindle (10) and a cutting head (22), from which a cutting tool (24) projects radially. In operation, an hydraulic force is applied between the cutting head 22 and the spindle (10) (specifically a flange (20) to which the cutting head (22) is secured, and a housing (26) mounted on the spindle (10)) to cause the longitudinal axis of the cutting head (22) to become inclined to the longitudinal axis L/A. of the spindle (10). Thus the cutting head (24) circumscribes a circle of larger radius; when the cutting operation is concluded, said force is removed, returning the cutting head (22) to a condition of colineality with the spindle (10), wherein the cutting tool (24) circumscribes a circle of smaller radius and can be withdrawn. <IMAGE>
