  • Patent number: 7815037
    Abstract: A conveyor comprises laterally spaced apart lifting/holding slats (12) and laterally spaced apart conveying slats (10) between the lifting/holding slats (12). The conveying slats (10) are advanced in a first direction for conveying a load and are retracted in a second direction for returning them to a start position. The lifting/holding slats (12) have lower portions (62) which reciprocate and upper portions (60) which move up and down. Cams (96, 98) operate in response to longitudinal movement of the lower slat members (62) to raise and lower the upper slat members (60). One end of the upper slat members (60) is connected to a fixed structure (18?) by a pivoting link (110) which pivots to permit up and down movement of the slat member (62) while preventing lengthwise movement of the slat member (62).

  • Patent number: 7604109
    Abstract: A trailer (T) and a dock (D) are provided with substantially identical slat conveyors (10, 12). Each conveyor (10, 12) has alternating conveyor slats (36, 36?) and lifting/holding slats (38, 38?). The trailer (T) is backed up to the dock (D). Upper portions of the lifting/holding slats (38, 38?) are coupled together at their ends. The confronting ends of the conveying slats (36, 36?) are also coupled together. A mechanism carried by the dock (D) raises and lowers the upper portions of the two sets of lifting/holding slats (38, 38?) a drive mechanism carried by the dock (D) where it reciprocates both sets of conveying slats (36, 36?).

  • Patent number: 7497056
    Abstract: A floor/ceiling 10 has downwardly extending ribs (14) separated by downwardly opening channels (16). The floor/ceiling member (10) sits down on a horizontal header (32) that is on top of a building wall that extends perpendicular to the ribs (14) and the channels (16). A preformed wall panel (24) has a lower strip portion (26) that is connected to a side flange (36) on the header (32). Preformed wall panel (24) has upwardly directed peaks (28) and upwardly opening valleys (30). The peaks (28) are sized and shaped to snuggly fit within the ceiling channels (16).

  • Patent number: 7380652
    Abstract: Separate manifold blocks are connected to the ends of tubular piston rod end portions of linear hydraulic motors that are parts of a drive assembly for a reciprocating slat conveyor. The manifold blocks are removably connected together by bolts and when connected complete passageways in the manifold block assembly that connect the linear hydraulic motors with each other and with pressure and return conduits. The end portions of the linear hydraulic motors are connected to transverse mounting frame members by spaced apart clamp assemblies. The clamp connections stiffen the end portions of the linear hydraulic motors and minimize deflection at the centers of the linear hydraulic motors.

  • Patent number: 7316307
    Abstract: An elongated plastic slide bearing (10) comprises a top (30), sidewalls (32, 34) depending from the top (30), and connecting to walls (36, 44, 48 and 38, 46, 50) that form laterally inwardly extending recesses (40, 42). Lock ribs (62, 64) extend upwardly and inwardly from the inner walls (44, 46) of the recesses (40, 42) to upper edges (66, 68). The upper edges (66, 68) are spaced below the bearing top (30). The bearing (10) is adapted to be set down onto a support beam (14) that includes laterally outwardly projecting lock flanges (22, 24) at its top. The lock ribs (62, 64) contact the lock flanges (22, 24). When the bearing (10) is pushed downwardly, the lock ribs (62, 64) bend outwardly and allow the lock ribs (62, 64) to move into a position below the lock flanges (22, 24). When that happens, the lock ribs (62, 64) assume substantially unstressed positions in which their upper edges (66, 68) are below the lock flanges (22, 24).

  • Patent number: 7303380
    Abstract: Corner seal sockets (26) are formed at the end of apex seal slots (58) formed in a rotor (10). A twisted split washer spring (70) is positioned in each socket (26) between the base wall (28) of the socket (26) and the inner end of the corner seal (16). The springs (70) bias the outer end surfaces of the corner seals (16) against the inner side surfaces of the housing sidewalls (20, 22). A radial apex seal slot (32) is formed in each corner seal (16). The base (38) of each slot (32) is substantially semi cylindrical in shape. It and the cylindrical peripheral surface (44) of the corner seal (16) form an arch shaped bight that connects side portions of the corner seals (16) together. End portions of the apex seals (18) extend into the apex seal slots (32) in the corner seals (16). The end portions of the apex seal biasing spring (60) contacts spring abutments (52, 54) which project radially inwardly from the outer ends of the apex seal (18).

  • Patent number: 7286355
    Abstract: A plurality of pouch bodies (14, 16, 18) are supported side-by-side from an assembly that includes a manifold block (26). The manifold block (26) includes an inlet manifold (28) and an outlet manifold (30). A liquid coolant (e.g. water) is delivered into the inlet manifold (28) via an inlet fitting (32). The liquid flows from the inlet manifold (28) into and through inlet passageways (36) which connect the inlet manifold (28) with inlet fittings (22) leading into a common end of the pouch bodies (14, 16, 18). The cooling liquid flows into the pouch bodies (14, 16, 18) and through them to outlet fittings (24) at the opposite ends of the pouch bodies (14, 16, 18). The coolant flows from the outlet fittings (24) through outlet conduits (38) to and into the outlet manifold (30). The coolant flows from outlet manifold 30 out through an outlet port (34). Electronic components to be cooled are placed between the pouch bodies (14, 16, 18).

  • Patent number: 7243779
    Abstract: Fixed conveyor slats (12) in the nature of beams extend over a window in support framework (53, 100, 102, 116, 118) for the movable and fixed slats (10, 12) in a reciprocating slat conveyor.

  • Patent number: 7243780
    Abstract: A screw (114) is rotated to move a head (110, 110?) against a first squeeze bar (30) and through a threaded opening (114) in a second squeeze bar (32), for moving the squeeze bars (30, 32) relatively together. This movement rotates cam bars (100, 102, 104, 106) in position, causing them to move a lower spread bar (24) away from an upper spread bar (22). This pulls downwardly on a bolt (16) which is connected to the lower spread bar (24). As the bolt (16) moves downwardly, its head (18) pushes downwardly on an upper clamp member (52?), moving it towards a lower clamp member (54?). This firmly clamps bottom flanges (78, 80) on a conveyor slat (70) between the upper and lower clamps member (52?, 54?), firmly securing the slat (70) to a transverse drive beam (56?).
