Title: Electric circuit breaker with safety reset
IPC: H01H71/16
Filed: 1960-06-09
Abstract: 889,414. Thermal switches. FREY, C. F., and MELVIN, M. F. June 9, 1960, No. 20272/60. Class 38 (5). A circuit-breaker whose contacts are opened by overload current through a thermallyresponsive tripping element has means to prevent the contacts being reclosed by the resetting member until the latter has been deactuated. The circuit-breaker comprises a fixed contact 16 co-operating with a movable contact 24 carried by a blade 23 secured to a tripping element 21 which may be all or partly bimetallic and is fitted with a copper reservoir stud 22. The ends of element 21 are pivoted between the housing end wall 12 and a clip 19 secured in an aperture 18 in the top plate 11, the element 21 being thus compressed to maintain contacts 16, 24 closed (Fig. 1). An L- shaped reset lever comprises a resilient leg 32 joined to a rigid leg 33, leg 32 sliding vertically against the housing end wall 13 and having a hook 34 engageable with the end 23a of the blade 23, whilst leg 33 passes through the aperture 18 to engage a reset pin 26 slidable in apertures in the casing 14 and top plate 11. The current circuit is through a terminal 13a, members 13, 12, 21, 23, 24, 16, and a terminal 17, so that on overload the element 21 snaps upwards to open contacts 16, 24, Fig. 2 (not shown). Subsequent depression of the pin 26 and the end of the leg 33 causes the element 21 to snap downwards, and forces the leg 32 upwards to engage members 23a, 34 and thus prevent closure of contacts 16, 24 (Fig. 3). Release of pin 26 allows contact closure and restoration of the L-shaped lever to the position shown in Fig. 1. The clip 19 may be bi-metallic to provide ambient temperature compensation.

Title: Improvements in device for indicating the pressure of air in containers, particularly in the inner tubes of vehicle tyres
IPC: G01L17/00
Filed: 1936-07-22
Abstract: 478,435. Electric signalling systems. KOEHNE, W. July 22, 1936, No. 20295. [Class 40 (i)] [Also in Group XIX] Relates to devices in which an electrical resistance connected in circuit with indicating-devices varies with the pressure and comprises a casing adapted to be attached to a valve nipple, and in series in the casing an inflating valve, a variable volume airchamber and a resistance varied by movement of the chamber. In Fig. 1, the casing 3 is secured to the tyre nipple 1 by a screwed sleeve 5 and packing 4 depressing the tyre valve 2. The casing 3 contains a non-return inflating valve 7, a duct 11, and a narrow duct 10 leading to an expansible chamber 8 which acts against a carrier 12 on which is a resistance 13 adapted to move past spring contacts 14. A spring 15 is located against the carrier 12 to move it back and also electrically connects the resistance to a contact 17. When the tyre pressure drops from normal, the chamber 8 contracts, the carrier 12 moves to the left and resistance is cut out of a circuit the electrical instrument of which shows a fall in pressure and a lamp which normally just glows becomes brighter. On a rise of pressure beyond normal the lamp becomes extinguished. In a modification, a resistance body is held between the carrier and a fixture and is cornpressed or extended as the carrier moves thus varying its resistance. In a further modification, Fig. 4, the air enters through the passage 10 as before and traverses a narrow annulus surrounding a closed tube 23 carrying on its inner surface the resistance 13 insulated therefrom. The air passes to a space 32 from which through a duct 30 it enters an expansible tube 29 moving it longitudinally. The tube carries spring contact pins 23 engaging the resistance. The air is compressed and acts as a spring to return the expansible tube 29. A contact plug 26 is screwed into an insulating plug 25 screwed into the casing.
