Title: Automatic temp. dependent disconnecting switch - has manual setting element on housing surrounded by annular spring
Inventor: HOFSAESS PETER
IPC: H01H37/54
Filed: 1974-07-09
Abstract: The temperature dependent switch is intended for disconnecting of electric loads when a preset temperature has been exceeded and for manual reconnection of the switching mechanism. It contains a bimetal snap-action disc whose centre part carries a current transmitting element, as in 1790103. The bimetal disc circumference is freely movable and abuts, in its snap-action position, the housing. The current transmission element is surrounded by an annular spring in its switching position, the spring force being smaller than the setting force of the bimetal disc. The housing (1) carries a known manually actuated setting element (5), acting upon the current transmission element (7). The arrangement also contains a counter bearing (12), effective only during the bimetal disc (6) buckling over in its switching-off position.

Title: Information indication with storage capability - involves layer of luminous substance on substrate excited by visible light
Inventor: PRICHODJKO ALEXANDER
IPC: G09F11/00
Filed: 1974-07-16
Abstract: Visible light is emitted if the layer of luminous substance is excited by means of a source of optical irradiation. The layer of luminous substance possesses inherent properties of afterglow. After the layer of luminous substance has been irradiated, a relative movement by mechanical means between the irradiated layer of luminous substance and the source of irradiation, makes the afterglow of the layer of luminous substance visible to the viewer. The duration of afterglow of the layer of luminous substance is influenced by at least one further source of optical radiation. The layer of luminous substance is deposited on the surface of a revolving roller.

Title: Laminated rotor for motor vehicle generator - has radial projections which are bent over to close slots after insertion of winding
Inventor: BANNO HIDEO
IPC: H02K1/06
Filed: 1976-06-19
Abstract: The laminated rotor, for a motor vehicle generator, has its slots designed to accept winding wires of relatively large diameter and to hold a larger number of these wires.
