  • Patent number: 5531637
    Abstract: A horizontal full automatic centrifugal fluidizing barrel processing apparatus which does not damage working environment and offers superior working efficiency. When two disk members are rotated together with a revolutionary shaft, a planetary moving mechanism provided in one of the disk members revolves rotary shafts around the revolutionary shaft and rotates the rotary shafts on their axes. Rotary pinching mechanisms installed in the rotary shafts (a part of a barrel pinching mechanism) pinch and rotate airtight cylindrical barrels. Hydraulic cylinders (the remainder of the barrel pinching mechanism) actuate the rotary pinching mechanisms on the side of one of the disk members to release the pinch of the barrels. A barrel handling mechanism 10 carries a released barrel out of the apparatus and set an untreated barrel.

  • Patent number: 5353879
    Abstract: A door includes an apparatus for reducing smoke associated therewith. The door is particularly advantageous in reducing smoke in a fire to thereby allow a firefighter or a victim trapped in a fire to readily indentify an exit. The door includes a nozzle or plurality of nozzles mounted upon the door, with a liquid source connected to the nozzle. Preferably, the door additionally includes a supply of pressurized water therein, with a surface active agent in an amount of 0.

  • Patent number: 5263317
    Abstract: Disclosed is an exhaust gas purifying apparatus for an automobile diesel engine including a pair of electrodes disposed at a predetermined interval in an exhaust path of an automobile diesel engine, and a high voltage power source for applying a high voltage to the pair of electrodes whereby an electric field is generated in a space between the pair of electrodes so as to collect diesel particulates. Since the diesel particulates emitted from a diesel engine are charged heavily in negative, and since the exhaust gas purifying apparatus forms an electric field between the pair of electrodes, the diesel particulates are collected on one of the pair of electrodes.

  • Patent number: 5167813
    Abstract: Disclosed are a process for laminating a functionally gradient material and a laminating apparatus for the same. The process therefor includes a suspending step and a functionally gradient material laminating step. In the functionally gradient material laminating step, solid-liquid separation is carried out to a suspension while varying the mixing rates of the suspension particles contained therein continuously or in a multi-staged stepwise manner. Therefore, the functionally gradient material layer thus laminated offers a composition gradient varying continuously or in a multi-staged stepwise manner in the thicknesswise direction thereof in a superior continuity, and the composition fluctuates less in the planewise direction thereof. In addition, the process and the laminating apparatus have obviated the atomizing and the spraying which adversely affect a working environment.
