Title: Mouldings with wooden inserts bonded directly to a plastic core - to make complex profiles with real wood faces
IPC: B29C45/14
Filed: 1974-09-10
Abstract: Composite moldings are prepd. with a wooden surface by lining a recess in a mould cavity with a veneer or layer of wood and then filling the rest of the cavity with an injection moulding material which will bond with the inner surface of the wood. Mouldings covered on opposite faces with pieces of wood are made by bridging the gap between the inserts with pieces of resilient, porous material which allows subsequently injected plastic to flood the interstices of the packing material without fouling the outer face(s) of the wooden insert(s). Esp. suitable for making shapes with sculptured profiles. The surface is of genuine wood, readily prepd. by stamping from prefabricated sheet. The core resin of e.g. polystyrene or polypropylene can be moulded to follow mutli-curvature edge profiles more readily than wood can be machined to corresp. shape. Composite structure does not involve ancillary adhesives.

Title: Trolley for placing boat in or out of water - has four lifting masts pivotal about transverse trolley axes
IPC: B60P3/10
Filed: 1974-10-08
Abstract: The trolley consists of a frame of two longitudinal members and a cross member supported on three wheels, with two parallel wheels rolling on the sides of a launching dock. The trolley is fitted with four vertical masts which pivot about base support brackets. The masts may be inclined to the vertical means of an adjusting bracket located between the members. Fore and aft support slings are attached to the tops of fore and aft pairs of masts. By varying the angle of each pair of masts it is possible to ensure that the pull on the slings is normal to the boat hull profile, thus making slipping impossible.

Title: Light amplifier or image intensifier - has reflecting layers on plane surfaces which are used to reduce due to heating effects
IPC: H01S3/093
Filed: 1974-11-20
Abstract: The light amplifier is designed to minimise distortion effects due to thermal gradients in the body (5) of the amplifying medium. The amplifier has plane faces, the face on which the pump ligth (6) is incident having a coating (7) which is transparent to the pump light and reflecting to the amplified light. The opposite face is coated with a layer (8) reflecting to pump light and transparent to amplified light. The design allows considerable reduction of the temperature gradient constant and reduces the equivalent curve of the sytem without affecting the amplifier gain. The temperature relationship, presuming that the medium is uniform, is given by a mathematical formula.

Title: Metal tank manufacturing system - includes weld flat plates together and passing through curved guides to form rings
IPC: E04H7/06
Filed: 1976-01-29
Abstract: The metal tank manufacturing system assembles the rings forming the tank body by bringing together a series of flat plates one after the other and welding them to each other before the bending operation. The sets formed are then slid along a curve of the same diameter as that of the tank and through special guides performing the bending operation, until the opposite ends are brought together and welded. The system avoids the use of conventional presses and thus greatly reduces the number of handling operations, apart from which the welded plates can be transported flat.
