Filed:

Jul 14, 1976

Appl. No.:

5/704880

Inventors:

Lorne W. Nelson - Bloomington MN
David J. Sutton - Minneapolis MN

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

G05D 2330

US Classification:

62202

Abstract:

A load shedding control device, for reducing the electrical energy demand of an electrical load apparatus having a load depending upon ambient temperature, having an ambient temperature responsive switch adapted to be connected in a control system of the electrical load apparatus for reducing the use of electrical energy by the electrical load apparatus as the ambient temperature increases. The ambient temperature responsive switch has its control temperature reset by an artificial heater energized proportionally to the percent of operating time of electrical load apparatus, whereby as the desired operating time of the load apparatus increases, the actual operating time is reduced to conserve electrical energy.

Abstract:

An accessory for inflating and deflating inflatable articles comprises a conduit 13, an intake 17, an outtake 19 and an injector 35. In use, conduit 13 functions as a venturi tube for rapid inflation and deflation of inflatable articles, preferably, articles having a large, low pressure air volume. For inflation, outtake 19 is connected to the inflatable article. For deflation, intake 17 is connected to the inflated article. For inflation and deflation, a source of pressurized air, preferably, an electric air compressor is connected to injector 35.
