Title: Dust collection meter for vacuum cleaner
Inventor: SASADA KIMIO
IPC: A47L9/19
Filed: 1991-08-08
Abstract: PURPOSE:To prevent the suction force of a vacuum cleaner body from lowering without the ambient air flowing into the vacuum cleaner body by fixing one end part of a diaphragm to the opening side of a pipe in an air-tight manner. CONSTITUTION:A bottomed cylindrical part 14 is slidably disposed in a pipe 7, and is urged by a diaphragm 15 toward to the suction port 8 side of the pipe 7 so as to close the suction port 8 of the pipe 7. The resilient diaphragm 15 is expandable disposed in the pipe 7, one end part thereof being fixed to a support part 14 so as to urge the support part 14 toward the suction port 8 of the pipe 7 and the other end part thereof being fixed to the opening 9 side of the pipe 7 in an air-tight manner so as to prevent air from flowing into the vacuum cleaner body from the suction port 8. When the volume of air passing through a dust collecting chamber is reduced due to build-up of dust in the dust collecting chamber so that the pressure of a storage chamber in which a motor driven blower is disposed becomes negative, the support part 14 in a dust collection meter is pressed by the ambient air, and accordingly, it slides so as to indicate the build-up of dust. At this time, the ambient air flows into the pipe 7 from the suction port 8, but is prevented from flowing into the vacuum cleaner body since the end part of the diaphragm 15 is fixed to the opening 9 side of the pipe 7 in the air-tight manner.

IPC: F23G5/30
Filed: 1993-08-11
Abstract: PURPOSE:To provide a fluidized layer incinerator to burn a car shredder dust by which fluidization is not prevented by accumulation of foreign matter on a perforated plate. CONSTITUTION:In a combustion furnace 5, a car shredder dust 6 forms a fluidized layer 9 together with fluid material 7 on a perforated plate 3 by means of combustion air 8. Foreign matter and ash after combustion gather at an upper part 17 of a discharge pipe 10 along the slope of the perforated plate 3. A mixture 18 of the foreign matter and the ash is fed to a foreign matter separator 20 by a screw feeder 29 that is mounted on a lower part of the discharge pipe 10. The mixture 18 moves along a sloping screen 22, and at this time, it is divided to the foreign matter 19 and the fluid material 7 efficiently by vibration given by a vibrator 21. The foreign matter 19 is then carried to a hopper 12 through a foreign matter discharge pipe 24. On the other hand, the fluid material 7 is sent to a fluid material recycling device 26 through slits 23 of the screen 22 by an operation of a double flap valve 25, and further recirculated to the combustion furnace 5 through an airstream transfer line 30 by an inflow of transfer medium gas 28.

Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce noise and wind pressure from a metallic pipe, having a circular cross section by roughening the outer peripheral surface by forming projections on the surface. SOLUTION: The outer peripheral surface of a metallic pipe which has a circular cross section and is made of aluminum, steel, etc., is roughened by forming projections 2 on the surface. The projections 2 are formed by spraying or brushing the paint, etc., mixed with fine glass particles.
