Title: Induction Apparatus Monitoring Structural Strains in Liquid-metal-cooled Nuclear Reactor
IPC: G01B7/24
Filed: 1980-06-26
Abstract: The reactor has strain gauges for monitoring the internal structure. Each gauge comprises electrical inductance apparatus wherein the inductance is varied by torsionally straining a ferromagnetic electrical conductor to vary magnetic coupling. The ferromagnetic member is of metal sheathed mineral insulated cable arranged in hairpin form. The hairpin form of the ferromagnetic conductor (1) causes torsion-sensitive signals in the two arms to be additive whilst on undesired signal caused by stray inductive coupling is self-cancelling. Alternatively, the induction apparatus may be a pair of co-axial tubular members of ferromagnetic material with the inner member surrounded by a non-magnetic conductor of solenoid form and having a linear non- magnetic conductor disposed coaxially, the magnetic coupling being created by differential torsional displacement of the tubular members. <IMAGE>

Patent GB-2071454-A (GB)
Title: Testing display systems
IPC: G01C25/00
Filed: 1981-03-03
Abstract: Head-up display units 2 and other display systems are tested by means of a camera 3 having an array 31 of light-responsive elements 310. The signals supplied to the display system to control the disposition of the display representation 200 in the display area 21 of the system, are compared with the output from the camera so as to derive an indication of the difference between the signalled disposition and the actual disposition of the representation. The display unit is mounted for angular displacement about two axes 29 and 30 at right angles to the line-of-sight 23. The width of the display representation is determined by measuring the distance between two points of the same brightness on opposite sides of the centre of the representation, this is done by displacing the image formed on the array across an individual element of the array. The brightness of the display representation is determined by comparison with a source 40 that is switchable between two known brightness levels. <IMAGE>

Title: Composite structure for joining intersecting structural members of an airframe
IPC: B64C1/06
Filed: 1981-04-21
Abstract: A joint between two structural members of composite graphite fibre or other fibre-reinforced material, which may for example form part of the frame of an aircraft, is provided by interdigitated fibres of two bundles 18 and 19 each of which eventually forms one of the structural members 14 and 16.

Title: Holding back pressure on the vent line in a blow out preventer control system
IPC: E21B33/06
Filed: 1982-02-18
Abstract: A blow out preventer control system controlling at least one blow out preventor 10 includes a hydraulic control valve 32 connected between the preventer 10 and a hydraulic pressure source 38 and vent line 42 for opening and closing the blow out preventer in which the blow out preventer is positioned at a higher elevation H than the control valve 32. The time of operation is decreased by holding a back pressure on the vent line 42 for compensating for the loss of venting fluid because of the hydrostatic head H. A predetermined back pressure is held on the venting fluid downstream of the control valve 32 by a resiliently biased check valve 60 connected between the control valve and the vent and which allows venting fluid in excess of the predetermined back pressure but prevents venting of the fluid at less than the predetermined pressure. Preferably the amount of the back pressure is approximately equal to the hydrostatic head. <IMAGE>

Patent GB-2099547-A (GB)
Title: Ball type universal joint and method of manufacture
IPC: F16D3/20
Filed: 1982-05-11
Abstract: A ball type universal joint construction where a ball member is rotatably received in a housing and a bearing structure interposed therebetween in a manner which limits the relative rotational degrees of freedom. The ball member has a spherical surface portion which includes axially extending bearing receiving slots and the housing has a cavity spherical surface portion which includes bearing receiving recesses in registry with the receiving slots. Ball type bearings disposed partially within the recesses and partially within the slots limit movement between the ball member and housing to articulated movement relative to each other. The housing also includes an access opening at one end face having an enlargement through which the ball member can be passed when rotated 90 degrees to its nominal, functioning position. This allows the ball member to be inserted into the housing through the enlargement while at the same time accommodating passage of the bearings into the housing recesses. Thereafter, the ball member is further rotated such that the receiving slots also partially receive the bearings and thus capture the ball member in an articulating, non-rotatable relationship in the housing.
