  • Patent number: 6283537
    Abstract: The Invention, a multipurpose utility trailer which converts into a workport or a camper, attaches to a standard axle assembly to become transportable. The frame, skeleton, and body components are welded coated steel, the cargo deck is pressure treated plank and the front deck and steps are coated expanded steel. The Invention is topped with detachable aluminum back cowling panels and a swing-up aluminum nose cowling which all interlock to create a flat, non-corrosive, self draining covering which is suitable for an elevated cargo or bunk platform. Removal of the back cowling panels exposes an open cargo deck with permanent sidewalls. Back cowling panels can be inserted into channels in the tailgate, thus becoming loading ramps. The nose cowling swings up to become a shielded counter top and the front compartment wall swings down and extends across swing-out braces becoming a camper floor.

  • Patent number: 5447003
    Abstract: A lumber predrying/drying kiln comprises a multiplicity of panels, a multiplicity of mats, and resin. Each panel comprises a multiplicity of plates and a block of insulation. The plates comprise fibrous glass strands embedded in a resin. The plates surround and encapsulate each block of insulation. Panels are placed next to each other, and above and/or below each other, end-to-end, to form walls and a roof of the kiln. They are connected with several alternating layers of fiberglass mats and resin wide enough to cover the joint between, and rigidly and structurally connect, the panels.

  • Patent number: 5329982
    Abstract: An internal combustion engine coolant extractor/injector with coupling comprises a tank assembly, an air pressure control assembly and a hose assembly. The air pressure control assembly creates a vacuum in the tank assembly by using the venturi effect. The air pressure control assembly does this by connecting to a compressed air hose. The air from the air hose flows through a venturi chamber creating a vacuum. The vacuum forces air out of the tank, creating a vacuum in the tank. The vacuum is maintained in the tank by means of a valve.A transfer hose is also connected to the tank. The transfer hose is inserted into an automobile radiator; in the alternative, the transfer hose is connected to an automobile radiator by means of a coupling. The valve is then opened. The vacuum in the tank pulls coolant out of the radiator through the transfer hose and into the tank.Coolant is injected or reinjected into the radiator by increasing the air pressure inside of the tank.

  • Patent number: 5088203
    Abstract: An eyeglasses measuring system comprises a fixed light source which projects a light beam onto two reflecting mirrors. The reflecting mirrors split the light beam into two separate light beams. One of the beams is positioned so that it tangentially illuminates the patient's cornea. A target mirror is then moved, by turning an adjustment screw. This adjustment positions the projection path of the second light beam tangentially onto the front surface of the patient's eyeglasses. The distance between the two beams of light is then determined by reading a scale.

  • Patent number: 4927103
    Abstract: A pipe support system comprises a pipe fitting and a pipe support. The pipe fitting is any standard fitting with the addition of two lugs added to the outside surface of the fitting so that they are diagonally opposite each other. The support has two arms joined together at the base and shaped so that they partially wrap around the fitting after installation. The inside surface of each arms is shaped to have a socket, the walls of which fit snugly against the respective lug after installation. The arms are fabricated of a stiff, elastic material so as to allow sufficient flexation of the arms during the installation of the fitting so that the fitting can pass between the tops ends of the arms without the support becoming permanently distorted.

  • Patent number: 4901863
    Abstract: A wood chip sorter comprises a shell (22) which at least partially defines a substantially cylindrical sorting chamber (26) into which wood chips are introduced. The shell (22) has a plurality of rotatable shafts (28) mounted thereon with the axes (72) of the shafts (28) being circularly arranged about a central axis (24) of the shell (22). Each shaft (28) has a plurality of discs (80) mounted at spaced intervals thereon with discs of adjacent shafts (28) intermeshing radially to form essentially axial spaces (84) therebetween. A drive and transmission system (30) revolve the shell (22) about the central axis (24) of the shell (22). A planetary gear system (32) facilitates rotation of the shafts (28) about their axes (72) as the shell (22) revolves. The discs (80) are shaped to have greatest axial width at central portions thereof, and taper to a lesser axial width at their circumference. The discs (80) are formed from an abrasion-resistant material.
