  • Patent number: 8869691
    Abstract: A mushroom compost compacting system and method includes a hydraulically activated tamper platen to compact compost held within a mushroom compost receptacle. The tamper platen has engageable arms extendable from opposite ends of the top surface of the platen and that each connect to a respective hydraulic piston or cylinder. The hydraulic pistons or cylinders link to respective ends of a brace bar disposed beneath the floor portion of the compost receptacle. Tamping compression of the tamper platen compresses compost between the tamper platen and the brace bar. In one embodiment, the hydraulic pistons are installed in or joined to fixtures, which fixtures may have trolley wheels therein to permit relative movement between the fixtures and guide rails supporting the fixtures so that the mushroom compost compacting system may be traversed along the length of all or a portion of the compost receptacle.

  • Patent number: 8342086
    Abstract: The invention relates to a drive device (1) for a bending press, in particular a folding press (2), comprising a press frame (3), a press table (9) and a press beam (11) that can be adjusted relative to the press table (9) via a hydraulic system (18) comprising a hydraulic pump (47), controlled drive motor (45), switch and control means and pressure lines and at least one pressure cylinder (12) which can be supplied with at least one pressure medium. The hydraulic system (18) forms a closed system together with a ring line (44) comprising the hydraulic pump (47), control valves (39, 41, 58, 84, 86, 87, 88, 89) and a pressure store (57). The ring line comprises a first line section (51) between a pressure chamber (23) of the pressure cylinder (12) and the hydraulic pump (47) and a second line section (53) between an additional pressure chamber (22) of the pressure cylinder (12) and the hydraulic pump (47).

  • Patent number: 8109314
    Abstract: A portable air clamp for use during lamination of substrates is provided. The clamp includes a top clamp plate, a bottom clamp plate and at least one flexible, expandable tube within a housing of the clamp. The top clamp plate is adjacent to a top housing and the bottom clamp plate is adjacent to a bottom housing. An expandable tube or bladder may be disposed in the top housing or the bottom housing. The clamp may also include alignment devices and mechanisms for ensuring proper alignment of the substrates during the laminating procedure. The clamp is adapted to provide uniform pressure along the surfaces of the substrates to be laminated.

  • Patent number: 6520075
    Abstract: A high precision, all-purpose, double action hydraulic press, which can control the speed, position, and parallelism of each slide, can conduct mold exchanges easily, and prevent the breakthrough phenomenon is provided with an outer slide 4, an inner slide 6, drive cylinders 8 and 9 which drive each of the slides, position detection devices 14 and 15 which detect the position of each of the slides, push pins 13, a damper cylinder 10 which prevents breakthrough phenomenon, and a die plate 5 which is equipped with push pins 13. By controlling the flow in the hydraulic pressure circuit which is connected to each of the drive cylinders, the speed, position, and parallelism of each of the slides are controlled.

  • Patent number: 6481346
    Abstract: The present invention provides an effective compactor apparatus and method for crushing empty recyclable containers. The compactor has a housing for containing the container to be crushed with a plunger that is able to be moved downwardly and rotated within the housing. The combined downward and rotational movement serves to achieve a maximally compressed container. The compressed container is ejected from the housing by further extension of the plunger.
