Title: Securing alignment pins for and optical fibre connector using thermally responsive material
IPC: G02B6/38
Filed: 1981-05-19
Abstract: In the manufacture of an optical fibre connector, a component is formed comprising three parallel triangularly-disposed pins 10. These are held in a jig 16 while a sleeve 32 of thermally responsive, e.g. negative temperature coefficient, material, which has been cooled to expand it, is placed around the pins. The sleeve extends beyond the pins and may also receive the front portion 34 of a connector body. As the sleeve 32 warms up it contracts and tightens both onto the pins 10 and the body portion 34. As an alternative to a negative temperature coefficient sleeve, a 'memory effect' metal may be used. The sleeve may be formed by part of the connector body (Fig. 3 not shown) or may be much shorter such that the rear ends of the pins are themselves received within the connector body (Fig. 2 not shown). <IMAGE>

Title: Casing of a gas turbine engine rotor
Inventor: WILKINSON WILFRED HENRY
IPC: F01D11/22
Filed: 1981-11-03
Abstract: In gas turbine jet propulsion engines, the radial extension undergone by rotor blades, when engine acceleration is performed, can result in fouling of the casing surrounding the rotors, with consequent damage to the rotor tips and, reduction in efficiency through excessive clearances having been created, during consequent low pressure operation of the engine. In order to avoid this, the present invention provides a construction in which the casing portion surrounding the rotor blades (16) is formed into a number of rectangular arcuately curved members (28), groups of which are moveable by unison bars (30) in directions radially of the rotor blades (16). The movement of the rotor blades (16) themselves initiates the generation of signals, either by changes in fluid pressure or electrical capacitance, with which to bring about movement of the members (28). The casing (18) going out of round will also initiate generation of the signals. <IMAGE>

Title: Sighting for indirect firing
Inventor: BECKER HERBERT
IPC: F41G3/16
Filed: 1983-07-07
Abstract: In a method of sighting for indirect firing, at a sighting position from which can be seen directly a target which is not visible from a firing position e.g. a gun site, the distances to the target and the firing position and the angles of the sighting position to the target and the firing position are determined and transmitted to the firing position for computation with the help of a range table or the like taking into consideration other variable factors. Use is made at the sighting position, or at or near the firing position when with a gun battery, of a mini-processor into which are inserted the values of the data pertaining to ballistic factors, such as blast pressure, temperature and wind components, the values for the elevation of the gun barrel as a function of the distance from the firing position to the target, and the other established values with reference to distance and angularity. The processor computes the geometrical data for the firing position and the necessary corrections and supplies the effective data for the bearing for aiming at the target and the angle of elevation.

Patent GB-2136720-A (GB)
Title: Joining silicon nitride to metals
Inventor: MOORE JOHN COLLARD
IPC: B23K1/19
Filed: 1983-11-14
Abstract: The problem of joining silicon nitride to a metal or metal alloy is overcome by bonding a surface of the silicon nitride to a layer of aluminium oxide or an aluminium silicon compound or magnesia or magnesium oxide or mullite, then bonding that first layer to a layer of nickel alumina before joining the nickel alumina to the metal or metal alloy by a conventional brazing or welding process. This has the further advantage of accommodating the widely differing coefficients of thermal expansion between the silicon nitride and the metal by the provision of materials between them which have graded coefficients of thermal expansion between the two extreme coefficients of thermal expansion. The method can be used to produce pistons having silicon nitride crown portions joined to aluminium or aluminium alloy piston bodies or to produce gas turbine blade assemblies having silicon nitride aerofoils joined to a metal root.
