Title: Remote switching for lighting - uses portable LF modulated VHF transmitter whose oscillator coils act as antenna
IPC: G08C17/00
Filed: 1976-01-26
Abstract: A remotely controlled switch is used to switch the mains supply to control lighting. The oscillator coils of a portable VHF transmitter act as an antenna to eliminate directional effects. The receiver is powered from the mains supply. Signals are transmitted from a modulated Colpitts oscillator circuit whose coils act as radiating elements. Signals are received by a super regenerative HF circuit followed by a pass band filter and limiter with a selective RC filter. Full wave detectors for each switching state have timing circuits to eliminate parasitic signals. The detectors drive a double flip flop whose outputs (Q, Q) control silicon bilateral switches (SBS) causing triacs in the load circuits to conduct.

Title: Cooler e.g. for extruded glass filaments - having hollow vanes containing vaporisable fluid to improve cooling
Inventor: GUNTER CHARLES EARL
IPC: F28D15/02
Filed: 1976-06-28
Abstract: Cooler includes a main cooling reservoir through which cooling fluid (e.g., water) passes and several vanes extending perpendicularly from the main reservoir. The filaments pass over the vanes. The vanes are hollow and have on their inner surface a fabric impregnated with a vaporisable coolant. Heat passing from the filaments onto the vanes causes the coolant to evaporate and circulate within the vanes. Heat from the coolant is transferred, to the cooling fluid in the cooling reservoir. Dissipation of heat generated by the extruded filaments is improved, so that the filaments are cooled more quickly.
