International Classification:

B08B 3/00

US Classification:

134147, 134 56 R, 134 941, 1341042, 134105, 134107, 134133, 134137, 134142, 134184, 134200, 134902

Abstract:

Apparatus for pressure processing components is disclosed which includes an improved closure system that minimizes dust-generating parts and allows easy access to the chamber. Ports are provided for introducing and releasing pressurized gases and fluids to and from the processing space. The heating system of the apparatus heats both the cover and the stage inside the pressurized chamber such that cycle time to equilibrate heated, pressurized fluids such as supercritical carbon dioxide inside the chamber are decreased. The apparatus includes a mechanism that raises the stage inside the chamber, pressing it against the fixed cover and sealing the inside of the pressure vessel. In one embodiment a screw-type jack is used to move the component-loaded stage fitted with a deformable o-ring seal a short travel distance to seat against the lid and seal the pressure chamber. In a related embodiment a computer and an electronic stepper motor are used to drive the pressing means in an automated fashion.

Abstract:

A motorcycle lifting device and carrier rack assembly for lifting and carrying a motorcycle on a vehicle is provided. The vehicle has a receiver hitch. The assembly comprises a carrier rail secured to the receiver hitch and alternatingly movable from a stowed position to a deployed position with the carrier rail receiving the motorcycle. A lifting and lowering mechanism lifts the carrier rail from the deployed position to the stowed position and lowers the carrier rail from the deployed position to the stowed position wherein the carrier rail remains substantially parallel to the ground in both the stowed position and the deployed position and during lifting and lowering of the carrier rail.

Abstract:

An extended tool holder for holding a cutting tool and receivable within a standard tool holder is provided. The extended tool holder comprises a body having a shank portion and a collet-receiving portion with an aperture extending through the body. A collet is receivable within the collet-receiving portion of the hollow body with the collet having a plurality of fingers closable about at least a portion of the cutting tool. A draw bolt is receivable within the shank portion of the hollow body and connected to the collet for urging the collet into collet receiving portion of the body wherein upon the collet entering the collet receiving portion, the fingers close about the cutting tool.
