Abstract: An automatic ignition control system for controlling the pilot burners and main burners of fuel burning appliances so that these burners are ignited only upon demand is disclosed. The system consists of a main control unit which may be interconnected with conventional main and pilot burners or which may be connected with a new and novel burner specifically designed for the purpose. The main control unit is actuated by suitable thermostats or switches when burner operation is required and operates to open the pilot valve and activate a pilot igniter control circuit. The igniter control circuit may take several forms, depending upon the type of igniter used with the burner, and sensing means are provided to deactivate this igniter control circuit when a pilot flame is detected. If the pilot fails to ignite after a predetermined period of time, the main control deactivates the pilot solenoid and sounds an alarm.

Abstract: The invention is an improved chemical firearm device that is operated and fired by an electro-mechanical system. The firearm device is of a pistol configuration, having a tank-like handle or hand-grip for containing the chemical to be discharged. A dual-action mechanical trigger mechanism is provided for first discharging the chemical through a nozzle in the barrel portion of the pistol-like device, which can be aimed like a pistol toward an assailant or target, and second to ignite the chemical during discharge if desired. An optional action is available whereby the ignition of the already discharged chemical on the assailant, or on the target, may be delayed until desired or needed in a point of close combat with the assailant or at the target. Another optional action is the availability of a high-voltage charge to stun and disable an assailant during close combat without the use of the chemical. Other uses include destruction of pest nests, and similar situations.

In one embodiment, the combustible gas contains a component which reacts with a catalyst to provide an additional heat increment to the gas in order to reduce the amount of electricity required. In other embodiments, a thermo-electric generator, heated by the flame of the lighter, generates electricity which recharges a rechargeable battery.

Abstract: A valve and switch assembly having a rotatably movable actuating mechanism in common. The actuating mechanism acts to actuate both devices when rotated. A latch mechanism, however, prevents rotation of the actuating mechanism when it is rotated to a first position. The latch is deactuated by axially depressing or collapsing the actuating mechanism and then rotating it. An additional unique feature lies in the switch assembly in which the switch contacts are electrically insulated from the actuating mechanism.
