Abstract: The invention relates to a holding tube for a heat treatment plant using injection heating. The holding tube includes a first, fixed section consisting of a conduit (5) of predetermined length and a constant counter pressure valve (6). The holding tube also includes a second, adjustable section. The second, adjustable section consists of a cyclone (7) and an inclining conduit (10) of a predetermined length. In the inclining conduit (10) there is disposed a device (28) for maintaining a defined liquid level in the conduit (10).

Abstract: A gas-fired water heater has a combustion chamber with a bottom wall defined by a perforated flame arrestor plate forming a portion of a flow path through which combustion air may be supplied to a burner structure within the combustion chamber. During firing of the water heater a combustion air shutoff system having a heat-frangible temperature sensing structure disposed within the combustion chamber senses an undesirable temperature increase in the combustion chamber, caused by for example a partial blockage of the flow path, and responsively terminates further air flow into the combustion chamber, thereby shutting down the burner, prior to the creation in the combustion chamber of a predetermined elevated concentration of carbon monoxide.

Abstract: Envisioned at a moment when energy efficient use of natural gas or propane is considered essential to human needs and environment, this device is designed to increase the efficiency of gas-fired-hot-water-tanks. This major household appliance, widely used in North America represents a moderate to heavy consumption of energy. It addresses the problem of heat loss incurred in virtually all domestic hot-water-tank systems. In effect it is the same as closing the vent on a fireplace after the fire is out to prevent the fire created draft from sucking the air from the room. This device prevents air from randomly reaching the flame chamber, controlling it instead. It allows the flame to function as normal, but closes naturally when flame is off, effectively reducing air flow and subsequent heat loss, which would otherwise have continuous negative effect.

Abstract: A flammable vapor detector is used to detect flammable vapors in the event of a volatile organic liquid spill near a gas fired appliance, such as a hot water heater. The appliance is mounted at an elevation above the floor while the detector is mounted at or near the floor where the spill may occur. The detector is connected electrically to a safety gas cut-off solenoid valve in the appliance to urge the valve to cut-off the flow of gas to the appliance in the event that the detector detects flammable vapor. Because the detector is below elevation of the appliance, the detector reacts to higher concentrations of flammable vapors than the concentrations of flammable vapors at the higher elevation of the appliance to turn off the gas to the appliance before the combustion air to the appliance reaches a lower flammability limit. The appliance used to describe the invention is a gas fired hot water heater.

Abstract: In a flow amount control device which control flow amount of fuel to be supplied to a high pressure fuel pump, an opening, which communicates with a port for passing fuel to the high pressure fuel pump, is composed of a first rectangular opening, a second rectangular opening whose circumferential length is larger than that of the first opening, and a third trapezoidal opening bridging between the first and second openings. The port communicates with the first opening, when engine speed is low, and, as the engine speed increases, with the third and second openings. Accordingly, the flow amount of fuel to be discharged from the high pressure fuel pump varies non-linearly and a change of the flow amount thereof is small in engine low speed region.
