Abstract: A liquid fuel for combustion appliances, in which a combustion wick for sucking up the fuel by the utilization of capillarity is used, contains an alcohol as a principal constituent and contains a hydrocarbon compound, which has approximately the same boiling point as that of the principal constituent, as a flame reaction agent. By the addition of the flame reaction agent, which is not accompanied by the occurrence of clogging of the combustion wick, the combustion flame of an alcohol, which otherwise produces a colorless flame, is colored and its visual perceptibility is thereby enhanced, such that the structure of the combustion appliance may be kept simple and the flame stability may be obtained reliably.

Abstract: 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.

Abstract: A lighting rod is provided with a rod-like top end portion and a main body, the rod-like top end portion being provided with a jetting nozzle for jetting out a gas, the main body being provided with a gas tank, a valve mechanism for opening and closing a path through which the gas is supplied from the gas tank to the jetting nozzle, a piezo-electric unit for generating a discharge voltage for lighting the gas, and an operation member which drives the valve mechanism and the piezo-electric unit in order to carry out a lighting operation. A safety device for the lighting rod includes a locking member which is supported for rotation on the main body to be rotatable between a locking position where it prevents the lighting operation of the operation member and a lock release position where it permits the lighting operation of the operation member, and a spring which urges the locking means toward the locking position.

Abstract: In a high-calorie gas appliance (1) which is set with a replaceable fuel gas cassette (9) containing therein liquefied gas and has a burner (7) for burning vaporized fuel gas from the cassette, a heat transfer plate (15) is mounted on the gas appliance with its one end portion disposed near the burner (7) and its the other end portion in contact with the fuel gas cassette (9) so that a part of heat of combustion at the burner (7) is transferred to the fuel gas cassette (9) to heat the same. Further, a heat accumulator member (2) is disposed in contact with the heat transfer plate (15) in the position of contact of the heat transfer plate with the cassette (9). Thus temperature drop of the liquefied gas due to vaporization latent heat in response to gas supply from the cassette is suppressed, thereby ensuring stable gas supply even if the amount of gas in the cassette upon initiation burning is reduced and ensuring exhaustion of the cassette upon quenching.

Abstract: This invention provides a gas lighter (1) in which a cap (7) can be surely and easily mounted on the lighter body. A chamfer (17) having an inclined surface is formed on one side of a recess (15) on a support post (16) of the lighter body. A trapezoidal resilient tongue (11) projecting inward of the cap (7) is formed at the hook portion (6) of the cap (7). The resilient tongue (11) slides on the inclined surface of the chamfer (17) into the recess (15), whereby the hook portion (6) is brought into engagement with the recess (15).

Abstract: A safety device in a lighting rod comprises a locking member having an engagement section, which interferes with a portion of an operation member and thereby locks the lighting operation of the operation member. The locking member can move in a direction, that intersects with the direction along which the operation member moves. An urging member urges the locking member to a locking direction. The locking member is provided with a lock releasing section, which can be operated in order to move the locking member in a direction, that acts against the urging force of the urging member. The lock releasing section is projected to a position, which stands facing the operating section of the operation member. The lock of the lighting operation is released by operating the lock releasing section of the locking member, and the lighting operation is carried out in this state by operating the operating section of the operation member.

Abstract: A fire-lighting device includes a jetting nozzle for jetting fuel gas, a gas passage for fuel gas to be burned extending from a fuel tank to the jetting nozzle, and a sintered filter made of sintered powder inserted in the gas passage upstream of a small-diameter portion. Provision of the sintered filter prevents obstruction of fuel supply by foreign matter clogging the gas passage at a nozzle plate of the jetting nozzle.

Abstract: 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.

Abstract: 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.
