  • 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?).

  • Publication number: 20090162341
    Abstract: A non-cytotoxic protein conjugate for inhibition or reduction of exocytic fusion in a nociceptive sensory afferent cell, comprising: (i) a Targeting Moiety (TM), wherein said TM is an agonist of a receptor present on said nociceptive sensory afferent cell, and wherein said receptor undergoes endocytosis to be incorporated into an endosome within the nociceptive sensory afferent cell; (ii) a non-cytotoxic protease or a fragment thereof, wherein the protease or protease fragment is capable of cleaving a protein of the exocytic fusion apparatus of said nociceptive sensory afferent cell; and (iii) a Translocation Domain, wherein the Translocation Domain translocates the protease or protease fragment from within the endosome, across the endosomal membrane, and into the cytosol of the nociceptive sensory afferent cell. Nucleic acid sequences encoding the protein conjugates, methods of preparing same and uses thereof are also described.

  • Patent number: 7510071
    Abstract: A plow (P) sits down on movable slats (10) of a reciprocating slat conveyor formed of the movable slats (10) and fixed slats (12) which are between the movable slats (10). The movable slats (10) and fixed slats (12) define valley regions between the movable slats (10). The plow (P) has fingers (92, 106) which extend into the valley regions. During the unloading operations, the plow (P) is moved rearwardly by the moveable slats (10), together with the load (L) that is on the conveyor. When the plow (P) reaches the rear end of the conveyor, it tips rearwardly and discharges the remaining portions of the load (L) off from the conveyor. Then, a teather (T) is wound onto a winch and used for pulling the plow (P) forwardly back into a forward parked position (FIG. 15).

  • 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.

  • Publication number: 20080070278
    Abstract: This invention describes a novel agent for the targeted control of a mammalian cell activity, in particular the agent is used to control the interaction of particular cell types with their external environment. The agent has applications as a pharmaceutical for the treatment of a variety of disorders. An agent according to the invention comprises three Domains B, T and E linked together in the following manner: Domain B-Domain T-Domain E where Domain B is the Binding Domain which binds the agent to a Binding Site on the cell which undergoes endocytosis to produce an endosome, Domain T is the Translation Domain which translocates the agent (with or without the Binding Site) from within the endosome across the endosomal membrane into the cytosol of the cell, Domain E is the Effector Domain which inhibits the ability of the Recyclable Membrane Vesicles to transport the Integral Membrane Proteins to the surface of the cell.

  • 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).

  • Publication number: 20070248626
    Abstract: A single polypeptide is provided which comprises first and second domains. The first domain enables the polypeptide to cleave one or more vesicle or plasma-membrane associated proteins essential to exocytosis, and the second domain enables the polypeptide to be translocated into a target cell or increases the solubility of the polypeptide, or both. The polypeptide thus combines useful properties of a clostridial toxin, such as a botulinum or tetanus toxin, without the toxicity associated with the natural molecule. The polypeptide can also contain a third domain that targets it to a specific cell, rendering the polypeptide useful in inhibition of exocytosis in target cells. Fusion proteins comprising the polypeptide, nucleic acids encoding the polypeptide and methods of making the polypeptide are also provided. Controlled activation of the polypeptide is possible and the polypeptide can be incorporated into vaccines and toxin assays.
