Title: Non-misting mirror
Inventor: SPORLE DENNIS NORMAN
IPC: A45D42/00
Filed: 1981-07-18
Abstract: A common mirror is caused to be raised in temperature, thus inhibiting the condensation of water vapour on its surface, by the heat transfer from a flexible pouch housed behind the mirror and into which is introduced a quantity of hot water, this being sucked into the pouch through a tube- like nozzle when the mirror stand is actuated in a prescribed manner. The pouch comprises a sealed water-tight bag with an attachment port for the nozzle and containing sponge material. When the mirror stand is pulled forward this is compressed by a pressure plate which is acted on by the inner cranked ends of the stand; reversing the action permits the sponge material to re- expand the bag and suck in water. The nozzle is attached to the pouch by a flexible collar which allows it to be folded and clipped behind the mirror housing. <IMAGE>

Patent GB-2095038-A (GB)
Title: An electric switch with a liquid contact
IPC: H01H29/28
Filed: 1982-03-08
Abstract: A switch comprises contacts (13, 14) and a constantly coherent volume of electrically conductive liquid (1) which, due to surface tension forces, has a minimum-energy state when located in a chamber (12), but an increased energy state when it is deformed on entering a constricted passage (15). Thus the liquid (1) is stable in the chamber (12) when interconnecting the contacts (13, 14) and is unstable when in the passage (15). The liquid (1) is moved by a pressurisable fluid medium in pipes (8, 9) or by an external force on the switch in a suitable direction. A dual chamber embodiment (fig. 1, not shown), acts as a bistable switch; the single chamber case is mono-stable, and a further electrode (16) may be located in the passage (15). The switch may be made attitude- independent by choosing dimensions for chamber (12) and passage (15) and volume of liquid (1) to ensure that surface tension forces predominate over gravity forces. <IMAGE>

Title: Switching off power in a torque sensitive clutch in a power tool
Inventor: FICKLING JOHN EDWARD
IPC: F16D43/208
Filed: 1982-12-09
Abstract: The torque sensitive clutch comprises a driving clutch member (10) and a driven clutch member (12) rotatable relative to one another when the torque transmitted across the clutch exceeds a predetermined value. A timing ring (48) has in one end two inclined grooves (50, 52) in which are located opposite ends of a transverse pin (54). The timing ring is rotatable with the driving clutch member but is axially movable relative thereto. When the timing ring rotates in one direction the ends of the transverse pin are located in the shallower ends of the grooves (50, 52) and when the torque exceeds said predetermined value the timing ring is moved axially away from the driven clutch member, the pin (54) trips a latch mechanism (62) gripping push rod (60) and the push rod moves under spring or fluid pressure to switch off the motor. When the timing ring rotates in the other direction the ends of the pin are located in the deeper ends of the grooves and the pin will not trip the latch mechanism regardless of the torque. Hence, the motor will only switch off when rotating in one direction. <IMAGE>
