Title: Tempering apparatus for glass sheets
IPC: C03B27/044
Filed: 1980-09-19
Abstract: A tempering assembly for glass sheets comprises a load station conveyor, a furnace conveyor, a quench unit conveyor and an unload station conveyor in succession as well as a drive unit operatively connected to each conveyor and adapted during transport cycles to operate the conveyors synchronously at the same speed to transport glass sheets from each conveyor to the succeeding conveyor and during oscillating cycles between the transport cycles to drive the furnace and quench unit conveyors, as well as the glass sheets thereon, in an oscillating manner, with the furnace and quench unit conveyors being driven at optionally different stroke lengths. To achieve this, the drive motor (5) is coupled to one of the furnace and quench unit conveyors (12,47) via fixed transmission means (25) and to the other conveyor via alternately actuated fixed transmission means (33,34) (during the transport cycle) and variable gear means (37) (during the oscillating cycle). <IMAGE>

Title: A plastics reflector for a headlamp
IPC: F21V29/15
Filed: 1980-10-03
Abstract: A plastics headlamp reflector is moulded or cast with a neck (2) forming a rear opening in which a metal bulb holder (1) is inserted. Integrally moulded arms (12) on the neck have forwardly extending free ends which bear inwardly projecting lugs (13) that engage in openings in the bulb holder to retain it in place. The front faces of the lugs provide locations for the bulb holder so that the same reflector mould part that forms the reflecting surface also forms these locating faces. Resilient bridge portions (16) of a front rim (15) on the neck (2) urge the bulb holder into engagement with said lug front faces. At its rear the bulb holder has a flange (6) closing an annular recess surrounding the neck of the reflector to form a ventilation channel connecting the headlamp interior to the exterior through peripherally spaced openings (9, 10). <IMAGE>

Title: Controlling fluid pressure actuated clutch of drive system
Inventor: SOMMER GORDON MAURICE
IPC: F16D48/04
Filed: 1981-08-13
Abstract: A heavy duty drive system includes a motor adapted to be drivingly connected to apparatus to be driven by means of a clutch unit 20 of the oil shear type which may be selectively actuated by application of fluid pressure. A control valve 26 controlling the application of actuating fluid pressure to the clutch unit is progressively adjusted (ie. closed) during clutch engagement by a stepping motor 98 operated by associated control circuitry so as to accelerate the driven apparatus in a predetermined manner by adjusting the valve successively at different rates, controlled by clock means 128, 134. Several such systems may be utilized to drive a common apparatus in which case the clutch actuating controls may be interconnected so as to provide progressive predetermined delay actuation of the various clutch units. Safety override means are also incorporated to deactuate the clutch unit in response to abnormal operating conditions such as jamming or overloading of the driven apparatus detected by means of a clutch output speed sensor 138. Rotation of a profiled flow-controlling member of the valve 26 in pulsed steps by the motor 98 dislodges contaminants from the valve inlet opening. <IMAGE>

Title: Method of locating non-metallic pipes and conduits laid under the surface of the ground
IPC: G01V3/12
Filed: 1981-12-30
Abstract: Non-metallic pipe or conduit 3, filled with water is caused to act as a dielectric. Transmitter 5' is coupled to the pipe or conduit 3 by way of a suitable coupler-in or buncher device or emitter 1 which generates, in the interior of the pipe or conduit 3, electromagnetic waves which radiate in the axial direction. Scattered or escaping radiation from this advancing electromagnetic wave takes effect also in the environs of the pipe or conduit 3 and spreads through the ground to the surface 6 as at 7. At the surface of the ground is a suitable movable receiving device 9, by movement of which the maximum field strength, and consequently the position of the pipe or conduit laid underground, can be located. <IMAGE>

Title: Background subtraction in a charge transfer device
Inventor: BALLINGALL RONALD ALEXANDER
IPC: H01L21/339
Filed: 1983-04-18
Abstract: In a charge transfer device (Figure 1) an auxiliary charge store and gate (GA) is provided adjacent to the devices input (9)-i.e. adjacent to the device source (S), or to the device first store (beneath GS), or to both. In order to provide background subtraction, charge is transferred back and forth, under auxiliary gate control, between the device input (9) and the auxiliary store (beneath GA) many times during each period of charge integration and a fixed increment of charge is removed for each such transfer. The total charge subtracted each integration period is dependent on the number of transfers; this latter is determined by the frequency of a control signal applied to the auxiliary gate (GA). This frequency may be set manually, or may be servoed by output circuitry in order to set an automatic adaptive threshold. The input to the device may be an infra-red sensitive photodiode (P), a plurality of such input arrangements being interconnected by CCD registers to provide an imaging array. The background subtraction arrangement may be applied to bucket brigade devices as well as CCDs. <IMAGE>
