Abstract: A conveyor for transporting a board along a path in a transport direction has an upstream section, a downstream section aligned with the upstream section and defining therewith a horizontal support plane, and a center section between the upstream and downstream sections. The center section is movable from a pass-through position aligned and level with the upstream and downstream sections to an offset position spaced therefrom horizontally or vertically. A platform underneath the center section is moveable vertically, and a lift moves the platform vertically between upper and lower positions. Hooks or grab can, when the center section is in the offset position and the platform is in the lower position, either pull a board off the platform and onto the downstream section or guide and deposit a board from the upstream section onto the platform.

Abstract: A housing for a laboratory appliance with a floor, ceiling, rear wall, side walls and front wall, which together enclose a work space. The front wall is movable between closed position and open positions. A work area in which liquids can be handled is provided in the work space. A filter device for ambient air is connected to the work space via at least one air outlet. At least one air inlet is connected to the environment, and a fan and an air filter are located downstream from the air inlet and upstream from the air outlet. An outflow opening is also located on the housing. The at least one air outlet and the at least one outflow opening are arranged on the housing such that, during operation of the filter device, the filter air stream flows substantially parallel to and along the work area.

Abstract: An anchoring system for use with a downhole tool includes a body with anchor members mounted on the body that pivot radially outward from the body and into engagement with an inner surface of a tubular. Curved slots are provided along a portion of the members and a sliding block has a protrusion that projects into the slots. The slots are curved so that when the block is urged axially within the body, the interaction between the slots and protrusions pivots the members radially outward. A piston is urged through the body to drive the block. Optionally, an elongate helical gear may cooperate with grooves formed in an edge of the members so that rotating the gear pivots the members radially outward.

Abstract: The tubular cutting tool for severing downhole tubulars, the tool having a drive system, a pivoting system, a cutting head, a cutting member, and a lubricant delivery system. Cutting may be accomplished by rotatingly actuating the cutting head with an associated motor and extending the cutting member away from the cutting head. The lubricant delivery system lubricates the respective contacting surfaces of the cutting member and the tubular and is actuated when the cutting member extends from the cutting head.
