US Patent:

45508186, Nov 5, 1985

Filed:

Oct 24, 1983

Appl. No.:

6/544791

Inventors:

Robert A. Holliday - Phoenix AZ

International Classification:

G07F 904

US Classification:

194 1D

Abstract:

A coin handling apparatus for use with a vending machine with the coin handling apparatus including an especially configured escrow box which is capable of handling relatively large quantities of coins without the coin jamming and incomplete emptying problems of the prior art. The special escrow box includes a coin return gate and a vend gate which cooperatively form a V-shaped escrow box when the gates are closed. The coin return gate is pivotably movable about a pivot point located at the vertex of the V-shaped escrow box and the vend gate is pivotably movable about a pivot point on its uppermost end so as to completely and rapidly open one entire side of the escrow box when the downwardly extending end of the vend gate is swung away from the vertex of the V-shaped escrow box upon opening of the vend gate.

Abstract:

A duty cycle controller for an air conditioning system. Solid state switches are connected in series with the heating and cooling switches of a thermostat in circuits for energizing the cooling and heating subsystems, respectively, of an air conditioner. A switch control circuit, when enabled, causes the solid state switches to be conductive when set and nonconductive when reset. Timing signals from a counter applied to the switch control circuit determine the state of the switch control circuit and thus the duty cycles for the heating and cooling subsystem. The controller is provided with a safety circuit which disables the switch control circuit to render the solid state switches nonconductive for a predetermined period of time after a power interruption or after a cooling or heating switch of the thermostat opens. The controller assures that each heating and cooling duty cycle begins with a full energization period. The length of the heating and cooling duty cycles can be readily varied.
