  • Patent number: 5630362
    Abstract: A refuse compacting device has dewatering capability and in some cases refuse transporting capability wherein refuse is fed into an outer cylinder in which an axially elongate piston is arranged. The piston is capable of reciprocating motion by a drive motor and threadable piston rod and nut arrangement, whereby refuse is forced towards an outlet of the cylinder. The cylinder is provided with apertures for allowing water to escape from the wet refuse as it is compacted against a conically shaped throttling member at the outlet of the cylinder.

  • Patent number: 5558301
    Abstract: In order that the acceleration suffered by the occupant (O) of an aircraft, particularly a rotary-wing aircraft seat in the case of an accident remains below a humanly withstandable limit, no matter what the size of said occupant, a seat is proposed in which a height regulation of the pan or bucket (16), in which the occupant is received, also has the effect of modifying the inclination of the energy absorbers (38). Thus, the vertical component of the retaining force exerted on the pan (16) by said absorbers decreases with the size of the occupant, which leads to the desired result.

  • Patent number: 5556082
    Abstract: A cushion unit includes a shock absorber and a suspension spring. The shock absorber includes an open/close valve and a check valve which are arranged in parallel with each other. To increase the height of a vehicle body, the open/close valve is closed so that a piston pressure chamber is allowed to communicate with a spring bracket pressure chamber via the check valve. This causes a hydraulic fluid in the piston pressure chamber to be supplied into the spring bracket pressure chamber under pressure. Accordingly, a cylinder spring bracket slidably arranged around a cylinder of the shock absorber moves upward due to the pressure increase in the spring bracket pressure chamber. Since a lower end of the suspension spring is held against the cylinder spring bracket, the upward movement of the cylinder spring bracket compresses the suspension spring to increase a reactive force thereof so that the height of the vehicle body is increased due to the increased reactive force of the suspension spring.

  • Patent number: 5356494
    Abstract: The invention relates to a high strength cold rolled steel sheet having excellent non-aging property at room temperature and excellent drawability, said steel sheet having a dual-phase structure composed of a high-temperature transformed ferrite phase and a low-temperature transformed ferrite phase having high dislocation density.The invention also relates a high strength cold rolled steel sheet having excellent non-aging property at room temperature and bake hardenability, as well as excellent drawability. This steel sheet is produced by preparing a hot-rolled steel sheet, cold rolling the hot-rolled steel sheet at a rolling reduction not smaller than 60%, annealing the cold rolled steel sheet at a temperature which is not lower than the .gamma. transformation start temperature but below the A.sub.c3 transformation temperature, and cooling the annealed steel sheet at a rate not smaller than 5.degree. C./sec but not greater than 100.degree. C./sec.

  • Patent number: 5245138
    Abstract: There is disclosed, a gross weight scale for filling material which can be poured or which can flow. The filling material is weighed by means of weighing cells and is filled by way of a filling connection into a bag suspended therefrom and is then compressed. In order to keep the weighing cells free of the compressive forces and so as to be able to check between each filling of the bag, the zero points of the cells in respect of permitted weighing tolerances, the filling connection is constructed as a structural unit which is separate from the filling container and is loosely suspended by means of a hanger arrangement from the weighing cells, which are attached to the filling container, and a decoupling arrangement is provided for bringing the filling connection out of operative engagement with the hanger arrangement.

  • Patent number: 5221138
    Abstract: A light fixture has opposed ends terminating in end panels, the housing having top and bottom walls and sides defining a light-emitting area, the top wall being provided with a rail. A pair of spaced lamp holders for supporting a fluorescent lamp is supported by insertable support means which are secured to the undersurface of the top wall. An elongated reflector extends between the ends of the housing and is positioned in the light-emitting area and fastened to the support means. A conduit-receiving opening is provided in each panel and is covered by a dome plug, each panel also having an opening for removably supporting a circuit plug. In a support system for adjustably supporting several light fixtures in an end-to-end relationship, each fixture having a top provided with a coupling member.

  • Patent number: 5213297
    Abstract: A tire display device having an arm assembly, a pivotable bracket assembly, and a plate assembly, the arm assembly comprising a wall bracket, an arm having one end secured to the wall bracket, and a free end pivotally supporting the pivotable bracket assembly for pivotable movement in a horizontal plane. The bracket assembly, in turn, supports a plate having peripheral flanges provided with slots for admitting respective slide arms having inner ends provided with threaded bores for aligning with respective radially extending slots in the plate so that a bolt can be passed through the slot into the threaded bore for adjustably securing the slide arm on the plate. The other end of the slide arm is provided with a pocket for engaging a bead on the tire. The slidable adjustability of the slide arms permit mounting of tires having different diameters. The plate is provided with a central opening for admitting a flanged bushing which is mountable on a shaft secured to a base of the pivotable bracket.

  • Patent number: 5195691
    Abstract: This invention relates to a tape winder for winding paper tapes, such as are particularly used as printed paper tapes in tape printer for documentation purposes, which tape winder comprises a driven reel hub, feeding and deflecting rollers and a tape tensioner arm. The reel hub is forklike and is laterally extractable to a limited extent and comprises preferably four winding rods, which are spaced 90.degree. apart so that the tape coil can freely be removed from the winder when the reel has been extracted.

  • Patent number: 5076549
    Abstract: A continuous dip-plating apparatus for a steel strip has a pot containing a metal melt which forms a plating bath, a device for causing the steel strip to run through the plating bath such that the steel strip makes a turn around a sink roll in the plating bath so as to be pulled upwardly above the surface of the plating bath, and a wiping device disposed above the pot and adapted for adjusting the amount of deposition of the metal melt to the steel strip. The apparatus further has a pair of flow regulating plates for suppressing deposition of dross to the steel strip. The flow regulating plates are arranged in parallel with and in the vicinity of the portion of the steel strip running upwardly through the plating bath with the upper ends of the flow regulating plates being disposed substantially at the same level as the plating bath.
