Abstract: In a gas appliance, such as a domestic gas fire or heater, there is provided a gas ignition device comprising a solenoid actuator which is electrically operable to cause a gas valve to initiate a gas flow, an igniter which is electrically operable to ignite the gas flow, and a remote control unit connected to the gas actuator and the igniter by a low voltage line. The control unit incorporates a power supply for providing a low voltage output and a timer circuit for applying the low voltage output to the line by actuation of a relay to cause gas ignition in response to manual actuation of a switch. Such a gas ignition device is advantageous because the remote control unit can be mounted at some distance from the appliance so that none of the circuit components of the remote control unit is subjected to high temperature in use, and there is no requirement for a high voltage supply to the appliance itself and only low voltages are supplied to the inside of the appliance.

Abstract: Method and apparatus are disclosed for checking the responsiveness of a circuit which senses the presence of a flame produced by a burner within a furnace. A programmed processor associated with the circuit measures the time the circuit takes to indicate the presence of a flame. A warning is generated when the measured time exceeds a predetermined allowable time. The allowable time is determined by taking into account the decreased responsiveness of an electrode that indicates the presence of the burner flame.

Abstract: An ignitor includes a first transistor, a transformer, an ignition member, and a switching control member. The first transistor is activated in accordance with supply from a DC power supply to perform switching. The transformer has a primary winding through which a switching current flows via the first transistor, a secondary winding for generating high voltage when the switching current flows through the first winding, and a tertiary winding for generating a control output for controlling the switching of the first transistor in accordance with the high voltage generated in the secondary winding. The ignition member ignites a target object using the high voltage generated in the secondary winding of the transformer. The switching control member prolongs the ON time for the switching of the first transistor in accordance with a decrease in at least one of the ambient temperature and the power supply voltage.

Abstract: An apparatus for outdoor recreation and survival which provides five simultaneous functions: portability, light, heat, a friction ignition system and a liquid heating system. It combines together elements of a burner fueled by a commercially available propane tank, mounted in a housing where the burner can provide both light and heat simultaneously when lit. The apparatus can simultaneously be transported by use of a handle attached to the housing. Light and heat are maximized through the use of reflective surfaces inside the housing which surround the burner. The improvement comprises a friction igniter attached to the housing for the safe and efficient lighting of the burner. The igniter is attached to the housing through a door/framework containing fire resistant glass to protect the user from any flames during ignition and use thereafter. Furthermore, an improved liquid container provides an energy efficient kettle that heats liquids.
