Title: Stowable sighting instrument
IPC: G02B23/16
Filed: 1980-12-17
Abstract: In armoured and fighting vehicles for example, the space available for stowing a sighting instrument is very restricted, whereas in use the instrument should be angularly moveable to cover a wide field of view. An instrument is provided comprising two complementary parts 2, 3 of a bearing, one part 3 being fixed in an aperture in the armour 1, the second part 2 being angularly moveable about a pivoting axis. The optical system comprises elongate objective (5) and ocular (5) portions extending in substantially opposite directions from the second part 2 on either side of the armour, said portions being oppositely offset from the pivoting axis to provide a stowing position for the instrument in which the two portions lie generally alongside the outer and inner sides respectively of the armour. The second part comprises means 15, 25 (e.g. prisms or fibre optics) for optically coupling the objective and ocular portions. The instrument may be a periscope or telescope. Figs. 3 and 4 (not shown) show periscopes having lenses. <IMAGE>

Patent GB-2100492-A (GB)
Title: Game-playing machines
IPC: G07F17/34
Filed: 1982-04-01
Abstract: A fruit machine comprises a control system 1 which supplies drive signals to reels 2 bearing symbols during a main game to cause the reels 2 to rotate at a normal speed such that the symbols appear blurred to the player in response to actuation of a game- initiating button 3 and to come to rest with a combination of symbols in a viewing zone. If this combination is a winning combination a prize is awarded whereas, if it is a feature combination, a slow-spin feature is made available to the player by a feature selector 6. When the slow-spin feature is made available the player may depress a slow-spin initiating button 7 and the reels are then caused to be spun at a slow speed by a normal/slow speed selector 8 such that the symbols can be individually identified as the reels 2 rotate. The player may stop the reels 2 rotating one at a time by depressing stop buttons 9 with the object of obtaining a winning combination in the viewing zone. Alternatively the slow-spin feature may be associated with one or more reels which differ from the reels which are spun during a main game. <IMAGE>

Patent GB-2132357-A (GB)
Title: Buried object location
Inventor: SOTHCOTT PETER
IPC: G01V3/06
Filed: 1982-12-17
Abstract: The detection of electrically non- conductive objects, such as plastics anti-personnel mines, relies on the fact that such an object appears as a local increase in the resistivity of the soil in which it is buried. To monitor the area of ground, an arrangement based on that shown in the drawing is used. Here we have two probes (3, 4) to which a constant level AC is applied, AC to prevent polarization problems, and two more probes (6, 7) to which a voltmeter (5) is provided. The meter reading indicates the potential gradient in the soil, and hence the resistivity thereof. If a non- conductive object is located the resistivity is higher than normal. Various arrays for applying this basic method are described. <IMAGE>

Title: Improvements relating to shelf storage systems
Inventor: ROSE HARRY
IPC: A47B87/02
Filed: 1983-03-14
Abstract: A shelf storage system can be built up in units, modular fashion, from a few basic elements. Side walls (1) have an array of horizontal ribs (4) on each side to receive the downturned lateral flanges (15) of shelves (2). These can be slid into position from the front, selecting any pair of opposed ribs, and they act as spacers for the walls. A rear wall (3) spans the side walls to act as an abutment for the shelves, and the uppermost one is secured to this wall to make it captive. Further units can be added to either side, using one extra side wall and a set of shelves, and the system can also be expanded vertically, with further side walls fitting on top of the existing ones. <IMAGE>

IPC: F24J2/46
Filed: 1984-01-05
Abstract: Apparatus for aligning a solar panel comprising a light tunnel with sides 1,3,5,7 for mounting on the solar panel or its support frame with a closed end 9 of the tunnel in which an aperture 11 is provided so that a beam of sunlight can pass through the tunnel and impinge upon a graduated scale 18 at the other end of the tunnel. The device is so arranged that when it is correctly mounted on a panel and the panel is arranged with its active surface normal to the rays of the sun, the beam of sunlight will impinge upon a centre point of the scale, indicating that the panel should be adjusted for optimum performance. Preferably the tunnel is substantially frusto-triangular in plan with the scale 13 being arranged at one angle the base of the triangle. The panel may be set so that sunlight falls on another scale point, and left so that the bright area moves through the centre to a further point, such that the panel is aligned throughout for sufficient efficiency. <IMAGE>

Title: Temperature control system for electrically heated hose utilizing hose simulator temperature detection
Inventor: LEHRKE KENNETH E
IPC: G05D23/19
Filed: 1983-10-19
Abstract: In coating systems wherein multiple coating components are separately applied by a hose to the point of application and are mixed and applied by a common applicator gun to a surface, e.g., the application of a urethane foam coating to a building roof, the quality of the applied coating is dependent upon the temperature of the coating components as well as the temperature of the surface to be coated, the latter temperature being proportional to the ambient temperature in the vicinity of the point of application. To insure optimum coating quality, the invention incorporates into the hose (16) a heating tape (40) having a resistance heating element (44) closely controlled by an electronic temperature control circuit (18) responsive to both an ambient temperature sensor (22) comprising temperature sensitive resistance (R3) and a hose simulator (60) separated from the hose (16) and having heat loss and absorption characteristics similar to the hose (16) and including a temperature sensing element (70) potted together with a resistor (58) in a mass of epoxy compound (59) to form a module (62) wrapped in an insulation blanket (64). The resistor (58) and sensing element (70) are spaced apart a predetermined distance selected to provide a degree of heat correlation comparable to the rate at which the hose (16) accepts heat from the heating tape (40) so that the temperature of the simulator (60) tracks the temperature of the hose (16) nearly identically.

Title: Soil cultivating implements
Inventor: VAN DER LELY ARY
IPC: A01B29/04
Filed: 1984-07-04
Abstract: A soil cultivating implement has a ground-engaging packer roller 8 located behind soil working members and substantially oblong scrapers 11 co-operate with the external surface of the roller 8 between groups of soil-penetrating teeth 10. Each scraper 11 is carried by a foot 12 mounted at the lower end of an upright arm 13 and each arm 13 is connected to a common carrier 20 of circular cross-section by at least one U-bolt 18 and a pair of clamping shoes 21. The nuts 19 of the U-bolt can be tightened so that each arm 13 can occupy a normal working position (full lines) in which its scraper 11 just makes scraping contact with the cylinder 9 but not such firm contact that rapid wear will occur. The degree of tightness of the nuts 19 is sufficient reliably to maintain this position under normal working conditions but, should a jagged stone or the like become tightly jammed between the neighbouring groups of teeth 10 so that it will tend to damage the scraper 11 and/or its mounting, the U-bolt 18 and shoes 21 will slip angularly around the common carrier 20 to move the scraper 11 into a withdrawn position (broken lines) before any damage occurs. <IMAGE>
