Title: Target Training Apparatus
IPC: F41J9/14
Filed: 1981-01-02
Abstract: Target training apparatus comprises a projector, a screen and a weapon fitted with an image intensifier. The image intensifier is responsive to infra-red radiation to produce a visible image and the projector includes beam generating means for generating a beam of radiation which has a visual component and an infra-red component and which transmits a target image to the screen and light control means for reducing the intensity of the visual component in the beam relative to the intensity of the infra-red component, whereby radiation emitted by the target image on the screen can be made representative of that emitted by a target at night or in poor visibility and so that the target image can be used in practice by a trainee marksman who aims the weapon at the target image using the image intensifier and fires from the weapon a projectile which forms a shot hole in the screen. In a preferred embodiment, the projector beam passes through the plane polarizing elements 30, 31, 32 which in the uncrossed condition transmit light to simulate daylight conditions and in a variety of crossed conditions transmit light to simulate a variety of dusk or night conditions. <IMAGE>

Patent GB-2105914-A (GB)
Title: Electromagnetic horns
Inventor: HENDERSON ROBERT IAN
IPC: H01Q13/02
Filed: 1981-08-27
Abstract: A corrugated electromagnetic horn 1 is formed of a loss-less dielectric plastics material 5 which carries the corrugations on its outer surface 7. A layer 8 of copper is formed in contact with the corrugations to constitute the electrically conductive walls of the horn. The corrugations can be machined in a simple manner, since they are readily accessible on the outer surface of the horn. In this way the difficulties generally associated with the manufacture of a corrugated horn, in which corrugations are machined out of solid metal on the rather inaccessible inner surface of the horn, are avoided. The precision with which a horn can be manufactured is therefore greatly increased and furthermore, the resulting product is very much lighter in weight than one machined from solid metal. <IMAGE>

Title: Method of internally coating pipeline and sealant therefor
Inventor: YAMAMOTO MIT SUO
IPC: F16L55/164
Filed: 1981-09-21
Abstract: A pipeline 1 needing leakage repair and/or prevention is filled with a liquid sealant of the aqueous emulsion type and in a foamed state from a foaming device 3. Then excess sealant in the centre of the pipeline is drained from the pipeline, and the sealant remaining on the interior wall of the pipeline is allowed to cure. The sealant is delivered to and drained from the pipeline by a blower 4 under the control of two valves 8, 9, which are selectively operated to connect the blower to the pipeline either via the foaming device or directly. The sealant may comprise an aqueous dispersion of an acrylic polymer containing fine particles of inorganic oxide weakly adhering to each other into aggregations. <IMAGE>

Title: Gas flow control valves
Inventor: FEATHERS LEONARD JOHN
IPC: A62B9/02
Filed: 1983-03-08
Abstract: In a demand valve for breathing apparatus gas flow is controlled by a valve disc 16 in accordance with the pressure in a control chamber 19. Gas vents from chamber 19 through an orifice 21 at a rate dependent upon the deflection of a diaphragm 27 sensitive to respiration and which controls the spacing of a spring arm 22 from the orifice 21. The arm 22 has a set spacing from the orifice 21 such as to provide "positive pressure" operation of the valve when the valve is connected into the mask inlet 5. A lever 36 contacts the inlet 5 and acts through a pin 32 to bias the arm 22 to its "positive pressure" setting through a second spring arm 24. When the valve is disconnected the lever 36 drops to allow the arms 22 and 24 to relax so that the arm 22 moves closer to the orifice 21 and thereby shuts off gas flow past the disc 16. The disc 16 is made has a flat member and takes up the bowed shape shown when held against its seat 14. <IMAGE>

Patent GB-2137545-A (GB)
Title: Screwdriver spanner or socket set
Inventor: GOO-TON LIN
IPC: B25B23/16
Filed: 1983-03-28
Abstract: A handle 2 is adapted to slidably receive a shaft 7 thereby to align a first toothed clutch face 72 on the shaft with a second toothed clutch face 41 in the handle. In this way pressure applied to urge the handle further on to the shaft causes the toothed clutch faces to couple together so that rotation of the handle produces rotation of the shaft. A spring 5 causes the two faces to decouple when the pressure applied to the handle is removed thus allowing free rotation of the handle with respect to the stem. The handle can include at least one slot 11 closed by a disc 13, the slot being adapted to receive drive heads for use with the screwdriver or the like. <IMAGE>

Title: Improvements in or relating to brake systems for tractor vehicle and trailer combinations
Inventor: GRAUEL INGOLF
IPC: B60T8/18
Filed: 1983-10-27
Abstract: Multi-circuit brake actuation member (3) is constructed to control electrical and pressure-medium- operated circuits (III, I and II). A trailer brake control valve (9) is controlled by circuits I and II of which circuit (II) is a pure control circuit from the brake actuation member for improved response. Electrical circuit (III) is used for the electrical control of pressure- control valves (14, 19) on the tractor vehicle and for the electrical control of the trailer brakes via lead 30. In the trailer, electrical and pressure medium control is simultaneous. In the tractor, the electrical control is predominant via solenoid valves 15, 23. Load sensing and anti-skid control means 26, 27 can be employed. If the electrical circuits fail the brakes are controlled by pressure medium. Other variations of tractor control circuits are described. <IMAGE>
