摘要:
A cassette type gas cylinder, containing liquefied fuel gas, for giving an alarm when the volume of remaining fuel is reduced to a predetermined level or less in order to provide an advanced notice of replacement of the gas cylinder with a simple structure using burst energy of discharged gas. A valve 12 for opening and closing the discharge of liquefied gas is arranged at the center on one end of a container body 11a. A gas flow channel 17, with one end thereof opened into a gas space formed above the level of the fuel when the gas cylinder is laid horizontally, is connected to the valve 12. A vibrating member 27, for producing a sound when vibrated and caused to collide with a body by the burst of the fuel gas, is disposed in the gas flow channel 17. This vibrating member 27 is connected to a damping member 38 by means of a coupling member 29. The damping member 38 is located below a predetermined level of the liquefied fuel gas, and is subjected to resistance while moving in the liquefied fuel gas. The damping member 38 suppresses the production of a collision sound made by the vibrating member 27 by providing the vibrating member 27 with resistance when the level of the liquefied fuel is above the predetermined level, but does not suppress the production of the collision sound when the level of the liquefied fuel is below the predetermined level, thereby giving an alarm indicating the reduction of remaining fuel.

A small-sized gas ignition device comprising a self-oscillation circuit, a piezo-electric transformer which steps up the output of the self-oscillation circuit, a capacitor which accumulates the output voltage of the piezo-electric transformer, and a discharging gap which is connected in parallel with the capacitor and is adapted to discharge the accumulated voltage for performing gas ignition. With this device gas ignition is obtained with certainty by single operation requiring only a light touch.

In a combustion appliance provided with a combustion wick for sucking up a liquid fuel by the utilization of capillarity and burning it, functions for automatically extinguishing the fire after the combustion has been carried out for a predetermined length of time are constituted with a simple mechanism. The combustion wick (6), which comprises a sucking section for sucking up a liquid fuel by the utilization of capillarity and a burning section for burning the sucked-up liquid fuel, is divided at an intermediate position into a burning section side subdivision (6A) and a sucking section side subdivision (6B). The combustion wick (6) is located such that at least either one of the subdivisions can be moved in a direction that comes into contact with the other and in a direction that separates from the other. The fuel is fed from the sucking section side subdivision (6B) to the burning section side subdivision (6A) when they are brought into contact with each other. The feeding of the fuel is blocked when the subdivisions are separated from each other, and a combustion time is thereby limited.
摘要:
A gas cylinder joined to a gas appliance. Based on the knowledge that a resonance frequency of cassette type gas cylinder does not vary with a residual quantity of gas therein a transmitter and a receiver are placed in positions opposed to a weld zone of the trunk portion of the gas cylinder and which permits an output voltage of the receiver with respect to a residual quantity of the gas to be detected at a specific resonance frequency of the gas cylinder. The resonance frequency is not lower than a predetermined level, the residual quantity of a liquefied gas in the cylinder being detected by transmitting the specific resonance frequency signal from the transmitter and detecting a reception output of not lower than a predetermined level by the receiver. This enables a residual quantity of the gas in the liquefied gas containing cassette type gas cylinder to be detected reliably from the outside.

A gas heater for heating a mat 12 soaked with an insecticide or the like, is heated by a catalyst reaction of a combustion gas, e.g. butane comprises a gas container 1, a gas burner 5 surrounded by a catalyst 6 which are contained in a burner 3 with apertures 3a, through which a pilot flame 81 from a pilot nozzle 8 ignited by a high voltage generator 9 is blown; a main valve 41 for the gas burner 5 and a pilot valve 82 for the pilot nozzle 8 and a high voltage generator 9 are controlled in a interlinked fashion.
摘要:
A liquid fuel burning device comprising a wick for sucking and burning a liquid fuel contained in a fuel tank by capillarity and a vent passage which is provided in a portion other than a fuel passage used by the wick and allows communication between an interior of the fuel tank and the outside air at least during combustion.

A liquid fuel burner has a wick for drawing up by capillarity of a draw-up section liquid fuel composed mainly of alcohol contained in a fuel tank and for burning it at a tip flame-producing section, a wick holder for holding the wick, an igniter for lighting the wick and a closure cap for preventing evaporation capable of sealing the wick openably and closably, and a flame-producing section of the wick is made noncircular in cross-sectional shape to increase the surface area exposed above the wick holder.
摘要:
In a combustion appliance provided with a combustion wick for sucking up a liquid fuel by the utilization of capillarity and burning it, the combustion wick is constituted, such that a flame length in accordance with the application of the combustion appliance can be obtained, such that little change in fuel feed rate may occur due to a change in amount of residual fuel, and such that the flame length may not change. The combustion wick (6) comprises a sucking section (61) for sucking up the liquid fuel and a heat-resistant burning section (62), which are made from different materials and connected to each other.
摘要:
A method for producing a filter for use in a fuel flow rate regulating mechanism has a first step of providing a sheet of microcellular polymer material having upper and lower surfaces, each of the surfaces being fused to prevent fuel flow through the surfaces. The sheet of microcellular polymer material also has formations of continuous air bubbles between the upper and lower surfaces. The method for producing a filter has a second step of heat pressing in the direction of thickness to rearrange certain of the air bubbles, redefining same as independent, nonconnected air bubbles. The method for producing a filter has a third step of transversely punching from the sheet a filter element of prescribed configurations.
