Title: Kerosene combustion wick
Inventor: SHIMIZU EIJI
IPC: F23D3/08
Filed: 1980-07-11
Abstract: PURPOSE: To prevent the production of tar due to the combustion of inferior fuel  and lengthen the service life of the wick by a method wherein a plurality of paper  like thin sheets made of heat resisting fibre are provided along the periphery of the  combustion part of the combustion wick for kerosene stove.  
     CONSTITUTION: The combustion part F of the combustion wick is formed by the paper like thin sheets 3 and a flame spreading wick 2 put one over another and stiched up with glass fibre thread 4. The thin sheets 3 are made of heat resisting  fibre in the size of not more than 4 micrometers such as ceramics or the like made  paper like and bound with organic binder such as polyvinyl acetate or the like. The  flame spreading wick 2 is mainly made of glass fibre, made cylindrically and arranged a little bit protruded above the tip of the sheets 3 in order to quicken the  flame spreading at the time of ignition. Because the sheets 3 are made paper like  with the fibres in the size of not more than 4 micrometers, their capillaries are so  small and many that the amount of oil to be held therewithin is large, resulting in  preventing the temperature of the sheets from being raised and consequently the  durability of the wick against inferior kerosene can be improved.

Title: Butterfly valve
Inventor: NAKANISHI MIKIMA
IPC: F16J15/46
Filed: 1981-06-22
Abstract: PURPOSE:To avoid the displacement of a valve accidentally due to action of fluid and prevent a leak of the fluid, by containing magnetic fluid in an elastic member, arranging the elastic member to the internally peripheral surface of a valve main body and arranging an electromagnet or permanent magnet to the internally peripheral surface of the valve main body or the peripheral edge of a valve plate. CONSTITUTION:A seat ring comprises a bag-state member 22 of thin thickness material and magnetic fluid 21, and is formed as a whole in very rich softness. Accordingly, when a valve is fully closed, the outside of the seat ring can be contacted under pressure to a valve main body by action of an electromagnet 51, further forcibly pressed by fluid pressure in a pipe also to a side wall surface in the downstream side of the annular groove formed by a stepped part 12 of a valve plate and a retainer 11. As a result, even if the seat ring is radially sucked to the outside and displaced, a potential problem for fluid to flow in through the inside of the seat ring and leak to the downstream side can be eliminated.
