Title: Anti-fouling covering for sub sea structures
Inventor: ARNOTT THOMAS CHRISTOPHER
IPC: F16L58/16
Filed: 1989-11-17
Abstract: The covering, comprises anti-fouling metal sheeting (13, 13', 20) which is adapted to enclose the surface (11) of a sub sea structure, and which has corrugations (14). The sheeting is in the form of a strip (13) which is transversely corrugated and is adapted to be spirally wound onto the structure. It is copper or copper-nickel. The process for applying the covering (13, 13', 20) to a tubular sub sea structure (11) comprises the steps of coating the surface to be protected with an elastomeric anti-corrosion material, applying the sheeting (13, 13', 20) of anti-fouling metal to the elastomeric material to enclose the structure to be protected, applying a pressure of the area of the sheeting to provide a restricting force thereto and vulcanising the elastomeric material. As the sheeting is corrugated the corrugations (14) allow movement of and changes in the circumference of the elastomeric coating to be accomodated during and after the vulcanisation process without undue stress on the bond between the coating (12) and the metallic covering (13, 13', 20). The sheeting (13, 13', 20) is corrugated such that the corrugations (14) extend longitudinally or substantially longitudinally of the structure (10). The sheeting may be in the form of several individual strips wound transversely onto the structure. The anti-corrosion material may be an epoxy resin which is cured chemically after the metallic sheeting has been wound onto the structure. The structure to be protected is normally an offshore structure but may be a structure for use in deeper waters.

A rotating stool (20) constitutes the connection between two link rods (16 and 18) which are placed in continuation to each other. The one part of the rotating stool (20) is linked to the free end of the first link rod (16) which at its opposite end is pivotally linked to a swinging rod system (26, 28, 30, 32). The second link rod (18) is linked to the other part of the rotating stool and at its other end it is linked to the operation platform (14). The two link rods are pivotal by means of each of their swinging devices (54-70) which are supported on the travelling frame (10, 12) and the rotating stool (20), respectively. The swinging rod system (26, 28, 30, 32) is adapted to communicate a swinging movement to the first link rod (16), the free end of which follows or yet is close to a leadline intersecting this end in one of the end positions of the link rod. At the same time, the rotating stool (20) of the swinging rod system (26, 28, 30, 32) is kept in a mainly horizontal position.

Patent GB-2261774-A (GB)
Title: A connector/adaptor
Inventor: BOWERS REX
IPC: H01R13/627
Filed: 1992-02-05
Abstract: A connector comprises a body with pins (5, 7) for reception in a socket outlet. The body comprises front and back portions which are hinged together, the axis (20) of the hinge being spaced from a peripheral edge (16) of the connector and adjacent to the front face (25) thereof. The back portion (13) has a part (16) extending between the hinge (20) and the peripheral edge (16), whereby the part (16) protrudes beyond the front face (25) when the portions are opened. The protrusion may prevent electrical connection between the pins and the socket outlet. The connector body may clampingly receive a two-pin plug and thereby act as an adaptor (fig 10, not shown). The two parts of the body may be secured by a captive screw (73, figs 17, 18 not shown) held in a cavity of the connector. The screw has a relatively thin shank between a screw-threaded end and a head end. The cavity traps the screw end when the screw is not in use. A hole in the cavity is screw threaded so that the screw may operatively protrude from it. Another hole in the cavity receives the shank. <IMAGE>

Title: Video signal processing
Inventor: BURL MICHAEL
IPC: H04N5/14
Filed: 1992-05-26
Abstract: In a method of video image motion compensation a plurality of motion vectors are derived by techniques such as phase correlation between pairs of images. In order to a produce a set of motion vectors which can be used to define substantially all the motions in an input image sets of vectors are derived from comparisons with preceding and succeeding images and are then combined to produce a set of vectors for assignment to an input image. Once the set of vectors has been derived they are assigned to the input image from where they can be projected to produce a desired output image. The vectors are assigned to individual elemental areas of the image and certain elemental areas have two (or more) vectors assigned to them. <IMAGE>
