Title: Projectile with parachute
Inventor: GREVILLIUS BO
IPC: F42B10/56
Filed: 1984-05-25
Abstract: The invention relates to a compression spring (15, 15') to improve the opening of a parachute (6), specifically a parachute for a pyrotechnical charge, preferably an illuminating charge (3), as soon as the illuminating charge and the parachute have been separated from its carrying ammunition unit in the form of a rocket, projectile or the like. The parachute (6) is folded-up inside a protecting cap (4) in the carrying ammunition unit. The compression spring, in its compressed condition is loosely inserted into the parachute (6) in its protecting cap and is retained in its compressed condition as long as the protecting cap encloses the parachute, but provides a positive separation force to open the parachute (6) as soon as it is free from its protecting cap (4) at the separation from the carrying ammunition unit. The compression spring (15, 15') is preferably a spring wire bent so that a number of legs (21, 22, 23) are formed which by means of its spring force are contacting the inner wall of the protecting cap via the intermediate parachute material. <IMAGE>

Title: Optical apparatus for laser welding pipes
Inventor: CHADWICK JOHN RICHARD
IPC: B23K26/04
Filed: 1984-06-28
Abstract: Laser welding apparatus includes a first mirror whose angle may be adjusted but which is fixed in position and on which a laser beam is incident. The first mirror reflects the laser beam onto a second mirror which may be rotated through at least 180 DEG  about the axis of the articles to be welded and which reflects the laser beam onto a third mirror whose angle may be adjusted and which may be rotated through at least 360 DEG  about the axis of the articles to be welded. The laser beam then passes to a focussing mirror which focusses the beam through a welding nozzle onto the surfaces to be welded. In use, the third mirror is continuously rotated about the entire periphery of the articles to be welded and the positions and/or angles of all the mirrors are adjusted to ensure that the laser beam is transmitted along the desired pathway.

Title: Photo-detector
Inventor: THOMPSON GEORGE HORACE BROOKE
IPC: H01L31/112
Filed: 1984-12-15
Abstract: A photo-detector in the form of an optical field effect transistor comprising a transparent semi- insulating InP substrate (1), a transparent p InP gate region (2), and n InGaAs channel region (3) and source and drain contacts (5,6). Light incident on the bottom face of the substrate is detected. The channel region is thicker and reduced in doping in comparison with a normal JFET in order to achieve efficient light absorption and low gate to source capacitance. The source and drain contacts are interdigitated to increase the area for optical absorption (Fig. 1). Alternatively, the channel region is a composite structure including a lowly doped layer for directing photogenerated carriers to a more highly doped layer (active channel layer) of reduced dimensions of reduced area and upon which strip-like source and drain contacts are disposed. The optical FET structures proposed facilitate integration with other circuit elements. <IMAGE>

Abstract: Apparatus for electroplating or deplating the interior of hollow objects comprises an electrode 4 for insertion into the object 1, a spacer 5 to space and insulate the electrode from the object, and a non-conductive inlet 2 and outlet 3 for sealed connection to the object for the passage of fluid. A method of plating or deplating the interior of a hollow object which is closed at one end comprises inserting a pipe 13 into the interior of an object 7 to be plated, charging the interior of the object with a fluid through the pipe and emptying the object of the fluid on completion of the plating step. The tube 13 may be wrapped spirally around electrode 12 in order to space the electrode from the surface of the tube. One or more of the plating steps may be effected by electroless plating. Tube 7 may be non-conductive. The spacer 5 or pipe 13 may be oscillated. The invention allows objects having an inside diameter of upwards of e.g. 2mm and a length of more than one metre to be uniformly plated. <IMAGE>
