Filed:

Dec 10, 1976

Appl. No.:

5/749232

Inventors:

Paul D. Kayfetz - Bolinas CA
Joseph McHugh - Mill Valley CA
James Dugan - Mill Valley CA

Assignee:

CMA, Inc. - Bridgeport CT

International Classification:

F23Q 232

US Classification:

431125

Abstract:

A device capable of burning household vegetable oil and producing a candle-like flame is disclosed. It includes a heat-resistant upright glass tube within which a fibrous wick is positioned, extending a short distance out the top. For supporting the tube and wick in a generally flat-bottomed container, such as a small drinking glass, a foot or stand having horizontally-extending projections and an upright sleeve may be connected to the bottom of the tube by insertion of the tube end in the sleeve. When the assembled tube, wick and foot are placed in a container and vegetable oil is added, at least to the level of the bottom of the wick, the extending portion of the wick may be ignited to produce a candle-like flame. The container is preferably transparent so that light is radiated in all directions, and a special container may be provided for seating atop a light-transmitting rod, so that light from the flame illuminates the rod.

Abstract:

Apparatus for use in a lighthouse station for automatically maintaining the output of the light source at a predetermined level comprises a chamber for supporting a cathode ray tube face panel and a source of actinic energy located in the chamber. An adjustable controller is employed for energizing the source. A light translator in the form of a quartz rod is disposed adjacent the energy source for monitoring its output. A light responsive device, coupled to the light translator, derives a control signal representative of the instantaneous energy level of the light source. Finally, means responsive to the control signal serves to actuate the controller to maintain the output of the source at a predetermined level.
