Title: Single pole-double throw thermostatic switch
IPC: H01H37/54
Filed: 1981-12-07
Abstract: A single pole double throw thermostatic switch has a resilient contact arm 64 which is movable by a bimetallic disc 18 between a pair of fixed contacts 80, 114, one of which is mounted on a bendable arm 62 so that the gap between the fixed contacts is adjustable by bending the arm 62 prior to attaching a cover 20 to the main switch body. Because the gap is set prior to the final assembly of the switch, substantial increases in precision and reliability are realized since the contacts may be observed during setting thereof. Furthermore, the necessity for an external gap setting adjustment screw on the switch is eliminated. <IMAGE>

Title: Self-resetting door latch
Inventor: JOY BRIAN RICHARD
IPC: A01K11/00
Filed: 1983-06-15
Abstract: In a pet door having an open frame (11) and a top hung flap (12) therein, a latch mechanism (10) allows unobstructed outward opening movement of the flap (12) in direction B, but normally bars inward movement in the opposite direction A thanks to a raised catch (15). The catch is pivoted (at 29) and is held from below in its raised position by a collapsible strut formed by a toggle (17); the toggle is braced by a spring (35) against an abutment (36) which maintains the toggle in an uncollapsed state. When the flap (12) is required to open inwards, an actuator solenoid (19) is energised to thrust the toggle (17) overcentre, away from the abutment, to a collapsible state, whereupon the flap (12) can displace the catch (15) downwardly and swing open the toggle (17) being fully collapsed as the catch is displaced. The spring (35) automatically resets the catch (15) and returns the toggle (17) to its original position against the abutment (36). The catch (15) is mounted on a support cradle (16) (pivoted at 30) to enable the catch to move momentarily out of the way of the flap (12) as the latter swings back to its closed and latched position. <IMAGE>
