Patent GB-2173285-A (GB)
Title: A device for projecting and priming an exploding charge laid underground
Inventor: LEVERATTO RENZO
IPC: F42B23/16
Filed: 1986-03-04
Abstract: In an extended range mine of the anti-personnel type, comprising an igniter 2 acting on a projection charge 26 in a casing 17 to be laid underground, and a casing 19, containing main charge 20 and splinters 21, which is ejected by the projecting charge, all of the most sensitive or dangerous elements can be taken out in a single operation. Accordingly a cartridge element 24 which can be taken out comprises detonators 14 and 25 for priming respectively the projection charge 26 and the main charge 20, as well as the projecting charge 26. In operation the gases from charge 26 act on container 19 via conduit 28 and space 23. At a predetermined height a pull string 34 attached to container 17 releases striker 30 to activate detonator 25 and hence auxiliary charge 29 and main charge 20. <IMAGE>

Title: Optical viewing apparatus
Inventor: ROGERS PHILIP JOHN
IPC: G02B23/12
Filed: 1986-05-08
Abstract: Optical viewing apparatus has an objective lens (1) for focussing radiation from a scene or object to form an image on a detector (2) and means (3) for producing a visible display of the image which is viewed through an eye-piece lens (4). The objective lens is designed to impose a substantial level of barrel distortion on the image and the eye-piece lens imposes a substantial level of pincushion distortion on the observer's view to give an appreciably improved central resolution of the viewed field. The radiation focussed by the objective lens may be visible or invisible, e.g. infra-red. <IMAGE>

Patent GB-2197957-A (GB)
Title: Sensor systems
Inventor: DUTTA SUSANTA KUMAR
IPC: G01L19/04
Filed: 1986-11-22
Abstract: A pressure sensing system for compensating the actual pressure value sensed by a pressure transducer 1 uses a CMOS microprocessor 3 to calculate initial correction coefficients for the particular transducer being used from four combinations of pressure sensed by the transducer and temperature sensed by a temperature sensor 2. The correction coefficients are then stored in a memory and used for correcting the sensed pressure values by the microprocessor according to variations in temperature. The microprocessor also programmes analogue compensating circuitry 4 via its input/output port lines to maximise the voltage swing input to the microprocessor by providing coarse corrections to the gain and offset of the signal from the pressure transducer. The object is to simplify the process of calibration, to remove the need for external adjustments of a transducer and to allow changes of transducer type without the need for external adjustments. <IMAGE>

Patent GB-2200728-A (GB)
Title: Viscous shear coupling
Inventor: TAUREG HERBERT
IPC: F16D35/00
Filed: 1987-12-09
Abstract: A viscous shear coupling comprises an inner coupling part and an outer coupling part supported on the inner coupling part to define a sealed annular space wherein are disposed annular plates rotationally fast with the inner coupling part interleaved with annular plates rotationally fast with the outer coupling part, the space being partially filled with a viscous liquid and the remainder of the space occupied by a gas. The plates are provided with perforations (2, 3) whose total volume is greater than the volume of gas contained in the coupling under atmospheric pressure, so that in use gas bubbles (5) in the viscous liquid tend to lodge in the perforations in the plates (upper Fig. 2) rather than between opposed surfaces of the plates (lower Fig. 2), thereby improving the torque transmitting ability of the viscous coupling. <IMAGE>
