  • Patent number: 4850268
    Abstract: A multi-purpose laboratory room for mobile applications. The room comprises a housing structure having an airtight laboratory unit and an entrance unit, an air-conditioning and exhausting equipment unit to be installed in the upper part of the housing structure and a drain processing equipment unit to be equipped in the airtight laboratory unit. The clean levels of the laboratory unit and drain processing can be selected in multiple steps by electrical signal control.The laboratory room is composed of the hollow wall structure in the wall, floor and ceiling, in which air pressure in the hollow parts are controlled. The filter is provided with a heating device. In addition, an autoclave automatic sterilizing device is incorporated for processing drain. A suspension type vibration-isolating device is also equipped.

  • Patent number: 4681210
    Abstract: Apparatus for feeding a bar or several bars in a vertical pile along a predetermined horizontal path extending through a bending station, where the bars are bent into desired shape. A first conveyor has mounted thereto a first gripper assembly, which releasably grips the bar or bars, for feeding successive requires lengths of the bar or bars to the bending station. Arranged collinearly with the first conveyor, a second conveyor has a second gripper assembly and coacts with the first conveyor for transporting the bar or bars through, and away from, the bending station with the progress of bar bending. The second gripper assembly is further movable up and down on the second conveyor. Upon completion of the bending of the bar or bars, the second gripper assembly grips the bent bar or bars while being lowered, then is raised for lifting the bar or bars out of engagement with the bending mechanism at the bending station, and then is transported by the second conveyor away from the bending station.

  • Patent number: 4653367
    Abstract: Two pairs of opposed feed rolls are rotatably mounted on the upstream and downstream sides, respectively, of a bar cutting mechanism with respect to the predetermined traveling direction of the bar. Each feed roll pair comprises a fixed feed roll on one side of the bar and a movable feed roll on the other side, with the movable feed roll being movable toward and away from the fixed feed roll. A drive mechanism constantly rotates each pair of opposed feed rolls, so that the bar is fed only when being pressed against the fixed feed roll by the movable feed roll. The feed roll pair on the downstream side of the cutting mechanism is further jointly movable laterally of the path of the bar against the force of a spring for lessening the load exerted thereon, and for preventing the bending of the bar, when the bar is being cut by the cutting mechanism.
