Patent GB-2095505-A (GB)
Title: Automatic focusing
IPC: G03B13/36
Filed: 1982-03-16
Abstract: An automatic focusing system for a zoom lens 1 of a camera in which a beam of infra-red light is directed towards a subject 6 from a light source 4 and a portion of the light beam reflected from the subject 6 back to the camera is sensed by photoelectric means 5. The angle between the emitted and reflected beams is translated by mechanical means into a mechanical movement which is a function of the distance to the point of reflection and the lens 1 is thereby focused. The path of the light beam passes through the lens 1, before reaching the photoelectric means 5. Thus the distance measuring area in the viewfinder is not changed in telephoto and wide-angle modes. <IMAGE>

Title: Fire extinguishers
Inventor: HEATH RICHARD CHARLES
IPC: F16K17/14
Filed: 1983-06-30
Abstract: A fire extinguisher device comprises a container of pressurised extinguishant having a venting port fitted with a burstable diaphragm (49) which is supported externally by means of a backing plate (53). On on removal of the backing plate by an appropriate actuator the pressure of extinguishant can burst the diaphragm to allow discharge of the extinguishant through the venting port. In order to reduce the forces required to actuate the mechanism required for removal of the backing plate, the backing plate is supported by an abutment (54) making rolling contact with a counter surface, such that the release of the backing plate (53) can be effected by rolling, rather than sliding, friction. To enable prolonged resistance of the extinguisher mechanism to harsh conditions, the backing plate and associated actuator mechanism are enclosed within a chamber sealed by means of a secondary burstable diaphragm. The burstable diaphragm may be provided with lines of weakness to promote bursting thereof without discharge of segments from the venting port. <IMAGE>

Title: Fluidised bed shell boilers
Inventor: CROSS HENRY FRANK
IPC: F22B31/00
Filed: 1983-12-16
Abstract: In a fluidised bed shell boiler (20), the sides of the bed within the furnace tube (21) are retained by vertical boiler walls (40) within the furnace tube (21). The walls (40) may include water tubes (41) or be arcuate panels mounted within the furnace tube (Figure 6). Fluidising gas may be fed to fluidising gas ducts (31) communicating with the bed from a plenum chamber including paddles movable into positions closing off at least some of the ducts (31) during initial start up of the boiler to reduce the amount of combustible gas (or hot gases) fed to the ducts (31) when heating the bed to its operating temperature. The ducts (31) may be formed by mounting halfround or U-shaped members on the bottom of the furnace tube (21), the ducts tapering along their lengths such that the gas passing into the bed exits at substantially the same velocity across the width and length of the bed. Control of the bed level may be effected by determining if material is passing out of an aperture set in the bed wall at the height at which the bed is to be maintained and then adding or substracting bed material as required. <IMAGE>

Title: Method of control mill motors speeds in a cold tamdem mill
Inventor: KONDO KATSUYA
IPC: B21B1/28
Filed: 1984-01-31
Abstract: Speed control means 14, 24, 34, 44 54 are employed for the purpose of controlling the speeds of the motors 12, 22, 32, 42, 52 driving roll stands ST1, ST2, ST3, ST4, ST5 of the mill. The speed control means are adapted to perform a drooping characteristic control function of such nature that mill-motor speed is caused to decrease in response to an increase in mill-motor current. A drop in mill-motor speed caused at a stand at which the material being rolled has been threaded is corrected and controlled so that the ratio between the mill-motor speed drop after the material has entered the stand and a speed reference value for the speed control means or the actual speed of the mill-motor is substantially the same between one stand and another. This ensures that the gauge ST5 is reduced to zero quickly after completion of threading. <IMAGE>
