Abstract: A metal-reinforced polyurethane shoe protecting the lower end of a wood support system from shallow water or moisture on a floor, said shoe comprising a high-density polymer impregnating a rust-resistant metal mesh, and attached to the bottom surface of a wood support system by means of a wood screw or like fastener, thereby protecting the wood support system from the water and moisture accumulating on a potentially wet surface, thus preventing the occurrence of dry rot in the lower end of a wood support system.

Abstract: A tension adjuster is mounted on and is part of an external fixation device comprising frame segments rigidly supporting fixation pins that pass through and immobilize fractured bones during rehabilitation. This tension adjuster securely attaches the fixation pins to the frame segments and adjustably applies tension along the fixation pins to more rigidly secure the fixation pins and to improve the immobilization of the fractured bones. The tension adjuster comprises a threaded slotted screw attached to the fixation pins and comprises a mounting nut having an aperture through which is drawn the threaded slotted tension screw while adjusting the tension along the fixation pins. A tapered pin extending into the aperture of the mounting nut and into a chamfered slot of the threaded slotted tension screw, guides the threaded slotted tension screw through the mounting nut during tension adjustments.

Abstract: A wall construction which comprises a wall panel and a conduit in the wall behind the wall panel, a protector secured in the wall in the area in which the conduit is located, the protector comprisng an L-shaped one-piece sheet metal member defining a base portion and a vertical portion being from about two to about eighteen inches wide and from about two to about eight inches high extending vertically behind the wall panel upwardly covering the portion of a wall in which a conduit is located, the base portion being from about two to about eighteen inches wide and extending perpendicular from the vertical portion adjacent a floor or ceiling of the construction from about two to about eight inches, and an indicia portion formed on the base portion extending outwardly from the wall panel for marking the location of a conduit after installation of a wall with the protector therein is described.

Abstract: An automobile air conditioning system for controlling the inside temperature of an automobile to maintain the inside temperature in a comfortable range or to protect the contents of the automobile from becoming overheated on excessively hot days or to prevent freezing on cold days when the automobile is parked or not in use is disclosed.

Abstract: A skimmer for decanting treated liquid from sewage treatment basins comprising a weir, barrier, sealing means and mounting means so constructed and disposed as to define a solids-free decantation zone of increasing size during lowering of the weir during decantation is described.
