Abstract: ABSTRACT        A double-deck transportation vehicle has an elevator platform proportioned to extend across the cargo compartment which is mounted on guide rails for vertical movement between a lowered position, an intermediate position and a fully elevated position.          When in the lowered position, the platform is located at the floor level.  When in the intermediate position, the platform is spaced from the floor and from the roof of the van to provide load storage compartments above and below the platform.  When in the fully elevated position, the platform is raised to about the ceiling level.  The platform drive mechanism is mounted in a drive compartment which is located within the platform.  Elevator cables extend from the drive mechanism to anchor points located adjacent the upper end of the guide rails.  The elevator cables extend within the cargo compartment of the van and are not exposed at the exterior of the van.  A latching mechanism is provided for releaseably latching the platform in the intermediate position.

Abstract: ABSTRACT An annular blowout preventer packer unit is disclosed having an annulus of elastomeric material in which is embedded metallic drive inserts provided in an outward circle about the axis.  Metallic lead inserts are provided in an inward circle about the axis.  The top and bottom plates of the drive inserts have two angled longitudinal forward surfaces which interface with reverse angled adjacent longitudinal rearward surfaces of the top and bottom plates of the lead inserts, respectively. When the BOP piston is closed, the drive inserts cause the lead inserts to advance inwardly a greater radial distance than the advance of the drive inserts.  The result is that less stroke may be required to close the blowout preventer, and a controlled, predictable, uniform movement of the lead inserts is achieved.  The drive inserts top plates are broad across their rearward lon-gitudinal surface operably covering the area behind the lead inserts on closure of the packer unit.  The shape of the drive inserts allows the lead inserts to be driven to a smaller diameter without opening up the back side and causing outer diameter elastomer loss to the unit.

Abstract: ABSTRACT OF THE DISCLOSURE    A self feeding furnace for the combustion or coal and the like consisting of a housing having a bottom, side walls, a first end and a second end.  A platform is spaced from the bottom of the  housing.      The   platform   is  movable longitudinally in relation to the first and second end of the housing.   A wedgeshaped guide having an inclined leading edge and a trailing butt end  is secured between  the side walls  of  the  housing  with  the  leading  edge  immediately adjacent the platform facing the first end of the housing. An auger is secured to the first end of the housing whereby coal may be fed from a hopper onto the platform.   A swing gate is positioned at the second end of the housing.  A drive motor is provided for moving the platform back and forth in a reciprocating  motion.    As the  platform  moves  toward  the second end of the housing burning coal which has accumulated at the first end of the platform is directed up the inclined leading edge of the wedge.  As the platform moves toward the first end of the housing burning coal which has travelled ever the wedge is pushed toward the second end of the housing by the butt end of the wedge.  The burning coal is ultimately reduced to ash and pushed through the swing gate.
