Abstract: A timing device for performing a switching function at dusk and at a specific time during the night. A synchronous motor drives a time dial at a first speed during the daylight hours and a double that speed after dusk through a power train including a lever arm driven by an eccentric to engage the teeth of a ratchet gear to rotate a cam assembly which actuates movable contacts through which the motor and a load controlled by the timing device are energized. Projections carried by the time dial engage cam portions formed on a star wheel to rotate the star wheel and the cam assembly to actuate the movable contacts to deenergize the load and the motor.

Abstract: AN ANNUNCIATOR MODULE ADAPTED FOR SELECTIVE OPERATION WITH EITHER A NORMALLY OPEN OR A NORMALLY CLOSED ALARM CONTACT FOR INDICATING BOTH AN ABNORMAL CONDITION OF A VARIABLE AND A RETURN TO NORMAL CONDITION OF THE VARIABLE. THE MODULE INCLUDES A FIRST RELAY HAVING TWO OPPOSITELY POLED WINDINGS EACH ENERGIZED THROUGH A SEPARATE PAIR OF TERMINALS WITH ONE PAIR OF TERMINALS ADAPTED FOR ASSOCIATION WITH A NORMALLY OPEN ALARM CONTACT AND THE OTHER PAIR OF TERMINALS FOR ASSOCIATION WITH A NORMALLY CLOSED ALARM CONTACT. WHEN A NORMALLY OPEN ALARM CONTACT IS USED, THE OTHER TERMINALS ARE CONNECTED BY A REMOVABLE CONDUCTIVE LINK. THE MODULE INCLUDES A SECOND RELAY CONTROLLED BY THE FIRST RELAY, AND A THIRD RELAY, WITH ALL THREE RELAYS CONTROLLING ALARM MEANS SO THAT THE ALARM MEANS IS ACTUATED BOTH WHEN THE VARIABLE BECOMES ABNORMAL AND WHEN THE VARIABLE SUBSEQUENTLY RETURNS TO NORMAL. A FUNC-
TION TEST SWITCH CONTROLS THE SECOND RELAY TO PERMIT A FUNCTION TEST OF THE SECOND AND THIRD RELAYS AND THE ALARM MEANS, AND THE FIRST RELAY CONTROLS USER''S EXTERNAL INFORMATION CIRCUITS. THE ALARM MEANS INCLUDES AN INDICATING LIGHT WHICH IS ADAPTED FOR CONNECTION TO A POWER SOURCE INDEPENDENT OF THE MAIN POWER SOURCE FOR THE MODULE.-

Abstract: A time-delay circuit, preferably for use for delaying application of full voltage to an electric discharge device, including a pair of spaced terminals for connection to a voltage source, a relay including a coil and at least first and second normally open contacts with the relay coil and the first normally open contact being connected in series with the pair of spaced terminals, the second normally open contact when in closed condition connecting one of the aforesaid pair of spaced terminals in series with a third terminal, a thermal delay device including a current-responsive heater and a third normally open contact, the latter contact being closed in response to a predetermined period of current flow through the heater, the heater of the thermal delay device being connected in series with the aforesaid relay coil between the pair of spaced terminals, and the first and third normally open contacts being connected in parallel with the heater of the thermal delay device whereby closure of the third normally open contact in response to the predetermined period of current flow through the heater results in sufficient current flow through the relay coil to effect closure of the first and second normally open contacts, closure of the first normally open contact maintaining energization of the relay coil and effecting deenergization of the heater, and closure of the second normally open contact connecting the third terminal to one of the pair of spaced terminals resulting in full voltage being applied to the electric discharge device.
