The presently intended use is for providing a cooking grill with a controlled temperature cooking space. An electrically controlled valve having high flow rate and low flow rate settings is interposed in the fuel line for at least one of the burners in the grill. A temperature sensor signals cooking space temperature to a controller that may be a microprocessor. The system includes a keyboard allowing the user to communicate a selected set point to the microprocessor and the microprocessor communicates status to a display.

In a preferred embodiment, the electrically controlled valve is placed in series fuel flow with one of the manually adjustable valves commonly found on cooking grills.

Abstract: A fluid flow control valve uses a servo valve to control the pressure in a main diaphragm chamber defined by a main diaphragm. The main diaphragm carries a main valve element that assumes either a low flow or a high flow position relative to a valve seat depending on which of two states the servo valve is in. When the servo valve is in the one of the two states creating the low flow position of the main valve element, the main diaphragm chamber pressure is regulated by a pressure divider comprising two flow restrictors in series connection between the inlet and outlet chambers of the valve. When in the other of the two states, the servo valve disables the pressure divider and allows the main diaphragm chamber pressure to reach the outlet pressure. The disclosure shows two versions of the invention. One version of the valve enters its low flow state when the servo valve is closed, and the other when its servo valve is open.

Abstract: Gas leakage protection apparatus includes a pressure-differential sealing device and a thermal electricity converting device installed at a burner head for converting the heat of the fire into electric energy which is supplied to a solenoid valve at a bottom of a body to ensure smooth flow of gas through an opening of a gas duct.

Abstract: A turn down device for regulating gas flow within a gas lamp that is of the general type having a lamp post and a mantel. The device has a conduit configured to allow gas to flow therethrough and a gas supply line connected to the conduit for supplying gas under pressure. A poppet valve having a valve seat and a magnetic poppet is provided along the conduit downstream of where the supply line connects to the conduit.

The popper is fabricated so as to have a selected size, shape and mass such that the gas flow from the supply line lifts the poppet away from the valve seat absent attractive forces induced at an electromagnet provided proximate the valve. As varying amounts of sunlight are directed upon the solar cell, electricity travels to the windings of the electromagnet that induces an attractive electromagnetic force upon the valve.

An electrical circuit has a photocell array which causes the electrical circuit to open the valve at dawn with a shot of electricity and closes the valve at night with another shot of electricity. A sensor in the circuit detects when the lamp is lighted and discontinues the spark.

Abstract: A timer for attachment to a stove operated by manually controlled gas control knobs converts an ordinary manually operated stove to a timer controlled stove without requiring a technician to cut in to the gas lines of the stove. The timer includes a housing with a knob rotating shaft mounted in the housing. A knob gripper is mounted on the end of the knob rotating shaft for gripping the manually operated fuel control knob of the stove.

In this way if the fuel control knob of the stove is connected to a fuel valve shaft, rotation of the fuel control knob rotates the fuel valve shaft to limit the flow of fuel to the burner on the stove.

Timing period modifying means are provided for automatically at various times progressively increasing the timing period initiated by the operation of the cigarette lighter, such as by a predetermined fixed percentage. Before the timer starts into operation, a smoking elimination program suitable to the user is selected automatically during a measurement period when the user's cigarette smoking rate is determined.

Abstract: This invention relates to oil burner installations which include a storage tank for the oil and a pump for delivering oil from the storage tank to a burner. When the storage tank is refilled with oil, sediment at the bottom of the tank is stirred up and placed in suspension. If the pump is operated while such sediment remains in suspension, the sediment may be drawn into the fuel line. Upon reaching the burner, such sediment may disable the oil burner installation by clogging the burner orifices.By preventing the oil pump from operating for a predetermined period of time after commencing to transfer oil into the oil storage tank, sediment is allowed to settle once again to the bottom of the tank. After the predetermined interval of time has elapsed, the pump and burner are once again permitted to operate, and the system then draws sediment-free oil into the fuel line and thence to the burner.
