Filed: 1980-06-23
Abstract: Each axle of the vehicle is provided with a respective pressure modulator (15, 16) connected to the intake manifold (21) and in dependence on changes in the distance of a respective axle (18, 20) from the vehicle superstructure the modulators (15, 16) regulate the application of a control pressure to headlight adjusting servomotors (6). Each servomotor (6) contains a working piston (3) which is spring loaded to shorten the illumination range in the event of system failure, the piston (3) being located in the working chamber (5) by a diaphragm (4). The system includes a correction element comprising a pressure modulator (13) connected to manifold (21) and a servomotor (14) which is connected to modulators (15, 16) and causes modulator (13) to feed to each headlight adjusting servomotor (6) a pressure determined by the instantaneous condition of the vehicle suspension. In a modified embodiment modulator 15 is connected to modulator 16 through a simplified correction element and modulator 16 is connected directly to servomotors 6. <IMAGE>

Title: Solar collectors
IPC: F24S10/75
Filed: 1981-04-16
Abstract: A flat plate solar radiation collector panel comprises a number of parallel lengths of an extruded EPDM rubber section which includes tubes for passage of heat exchange liquid. The lengths have engagement formations (4 and 5) at their long edges so that a mat of the engaged lengths may be assembled, and the tubes are connected to a pair of copper headers (11). The undersurface of the tube mat so formed contains no recesses or keying formations. It is secured to a base 7 of the collector panel by a cement which forms a strong bond with the base 7 and a weak bond with the mat. The panel is easy to assemble in situ and, because of the weak bond, to dismantle when required. The tube mat behaves as a single sheet and not as a plurality of separate sections so a weak bond will still retain the mat even if there are areas of failure of the bond between the cement and the mat. <IMAGE>

Title: Device for Limiting the Firing Sector On a Combat Vehicle Particularly a Combat Tank from a Command Station
IPC: F41A17/08
Filed: 1981-06-12
Abstract: A device for limiting the firing sector during training on a combat vehicle, e.g. a combat tank, when supervised from a command station; a radio transmitter being provided at the command station and a radio receiver is provided in the combat vehicle, and wherein the radio transmitter (1) is connected to a device (11) for producing a firing-release signal which consists of two low frequency signals which are independent of each other and the frequencies thereof are not a harmonic one of the other, the radio receiver 2 is connected to a firing- release device 12 which blocks the electrical firing pulse which can be supplied to it by the firing device when no firing-release signal has reached the radio receiver (2), and releases the firing pulse when the complete firing- release signal has been received. By the use of the non-harmonic signals, accidental firing-release cannot occur by the presence of interference signals which may be a harmonic of the control signal. Preferably the firing- release signal is provided with two keying devices one of which controls one of the low frequency signals.
Patent GB-2079970-A (GB)
Title: Improvements in or relating to optical cable elements
IPC: B29C55/22
Filed: 1981-07-09
Abstract: An optical cable element comprising a tube of rubber or plastics material loosely enveloping an optical bundle is made by causing separate optical fibres to travel in the direction of their length, each under a controlled tension, assembling the advancing optical fibres together to form an optical bundle in which the positions of the optical fibres relative to one another are constant and extruding a tube of polymeric material around the advancing optical bundle. The tube is extruded in such a way that its internal diameter is greater than the diameter of the optical bundle and the extruded tube is drawn down to reduce its internal diameter to such an extent that the tube loosely envelops the optical bundle. The drawn down tube is then annealed to reduce the risk of subsequent shrinkage of the tube. <IMAGE>

Title: Method for controlling the emitted heating effect from a furnace which is fired with solid fuel
Inventor: LARSSON CARL RICHARD GOESTA
IPC: F23N1/00
Filed: 1982-01-29
Abstract: Means controlling the emitted heating effect from a furnace which is fired with solid fuel. In the furnace the fuel (11) is fed to a zone of combustion (13) where it is combusted with excess air. Characteristic for the invention is that the fuel (11) is made to create an approximately evenly thick, air pervious layer, in said zone (13). During the combustion the air of combustion is forced from one side of said layer (13) to the other, the over pressure being sufficient for optimal combustion, but independent on the emitted heating effect. The regulation against a decreasing heating effect value is carried out by means of a corresponding screening of the other side of the layer. The regulation against an increasing heating effect value is carried out by means of a corresponding exposure of the other side of the layer, which is equal with a decrease or increase, respectively, of the volume of the zone of combustion (13).

Title: Pressure sensors
Inventor: KIRMAN RICHARD GEORGE
IPC: G01L5/22
Filed: 1983-06-20
Abstract: Automatic (robot) machinery often any incorporates hand-like equipment for grasping/gripping an object. One recurring difficulty is that of providing the hand with feedback enabling it to monitor the exact manner in which the hand is holding the object, specifically to provide useful data as to the shape of the object and its position relative to the hand. The invention provides an area- extensive pressure sensor device, suitable for incorporation into a mechanical hand, that produces an output signal describing the spatial variation of the pressure applied to the device's sensory surface, by use of linear sequential scanning of the sensor surface to give, as a time- based output, a signal corresponding to the position-based pressure, the device comprising: a first, piezoelectric, layer (1) carrying a second, charge sensing, layer (6,7) the output of which is pressure dependent; means (4,2,22) for launching a deformation wave along the piezoelectric layer; and means (28,29,24) for correlating the sensor layer output with the position of the deformation wave. <IMAGE>
