Abstract: A blade sharpener includes a support rod, a blade clamping portion which is movable along the support rod, and a guide block which is located along the support rod, the guide block further having a honing tool rod extending through it which allows the honing tool rod to rotate freely about the support rod and substantially away from the horizontal to provide almost limitless motion and incrementally precise angular positioning of the honing tool rod relative to a blade secured within the blade clamping portion.

Abstract: A rotisserie cooking unit has a centrally configured heat source, a pair of removable spit carriers and a pair of removable covers which are configured to provide the function of covering and enclosing the unit and of opening up to serve as drip pans and ash catches.

Abstract: A method and apparatus for supplying and delivering fluids at a constant pressure includes means for measuring fluid pressure, means for measuring fluid flow and means for actuating fluid valves to control fluid pressure and flow through the valves. A programming means is also included so that fluid pressure and flow measurements are processed and the fluid valves are actuated according to a preprogrammed scheme.

Abstract: A fluid dispensing apparatus is provided with at least two identically configured reservoirs, each of which may be functionally adapted to serve as the washer portion or the collecting portion of the apparatus.

Abstract: A veterinary mouth prop is molded from a single piece of radiolucent material and has two external surfaces adapted to engage the occlusal surfaces of the molars on one side of the patient's mouth.

Abstract: A small sharpening device for ice skates that is intended to be carried in a person's pocket, which can be adjusted to fit and to sharpen all existing ice skates having either concave or flat-ground blades. The sharpener has two side pieces that form a gap to fit around the ice skate blade and a central flexible grinding cylinder that as the sharpener is moved back and forth along the skate blade adjusts to and sharpens either concave shaped blades or flat-ground blades. The round central cylinder can be replaced when worn out or when a polygon shaped grinding cylinder is required for certain flat-ground blades. The adjustable, parallel sides prevent the sharpener from rocking from side to side as the device is moved back and forth along the blade.

Abstract: A shift detecting element originates from an element cavity, a portion of which is defined in one portion of a mold section and another portion of which is defined in another cooperating mold section. The detecting element is cast as an appurtenance to a principal casting and is configured such that it can be easily removed from the principal casting. Misalignment or separation is determined by inspection and/or measurement of the cast shift detecting element.

Abstract: A bird feeder assembly has a feed bin and a feed bin cover and utilizes a plurality of extension members and a plurality of complementary shoulder members to slidably and securely engage the feed bin within the feed bin cover.

Abstract: A roof edge fascia system has a base member and a fascia member to secure the edges of a roof-top waterproof membrane and to secure the edges of paving blocks or insulation sheets covering such membrane at the roof edge.

Abstract: A film strip holder for use in backlighted message displays is an extrusion having longitudinally extending, light opaque upper and lower portions and a longitudinally extending light translucent center portion such that a film strip placed between the upper and lower portions is in light transmissive relation to a light source within the display, the holder being engagable in substantially light-tight tongue and groove relationship with adjacent holders.

Abstract: A band saw blade fixture has a number of symmetrically situated pins extending from one side of a flat plate and separated by a void therebetween to hold the abutted ends of a flexible band saw blade therebetween.

Abstract: An automatic off/on circuit for monitoring data receiving devices which turns the power to such devices "off" when data is not received for a first preset period of time and which turns the power to such devices "on" after a second preset period of time to restore reception of transmitted data.
