  • Patent number: 4995806
    Abstract: An oil stove comprises a combustion wick for burning oil, a device for extinguishing the fire at the combustion wick, and a deodorizing device for absorbing or removing gases causing smells that are produced when the burning portion at the combustion wick is extinguished. The deodorizing device comprises gas sensing means for detecting the generation of the gas, and suction means responsive to the gas sensing means for absorbing or removing the gas.

  • Patent number: 4704085
    Abstract: A movable wick type oil stove which comprises a wick for absorbing oil to provide a fire at the top of the wick, wick cylinders defining a space for disposing the wick therein means for moving the wick in the vertical direction along the wick cylinders, and a deodorizing device for absorbing or removing gas causing an undesirable smell and produced when the fire at the top of the wick is extinguished by lowering the wick to a predetermined position. The deodorizing device comprises a suction device, a movement-sensing element for sensing the movement of the wick, and a temperature-sensing element for sensing a temperature around the wick.

  • Patent number: 4577075
    Abstract: An earthing switch for gas-insulated switchgear apparatus is disclosed, in which conductor within an enclosure is provided with a stationary contact, and a moving contact is movably provided to connect with and disconnect from the stationary contact by an operating mechanism within an operating mechanism case which is mounted on a branch tube of the enclosure interposing an insulating plate therebetween. For connecting the moving contact to the enclosure electrically, a plurality of earthing bars are employed, and further, directions of electromagnetic forces generated between the moving contact and individual earthing bars are considered in the connection of the earthing bars. By virtue of the connection of the plurality of earthing bars, the influence of the electromagnetic forces acting on the moving contact can be reduced to a great extent.
