Abstract: This mitt, which is completely free of asbestos fibers, comprises hand and thumb sections, each of which is made from a wood knit liner enclosed in a layer of woven material made from temperature-resistant aromatic polymide fibers which are sold under the trademark "Kevlar". Layers of aluminum foil and flexible fiberglass are incorporated between the inner and outer layers of the hand section to increase its protective properties. Secured to the outer surface of each section is a pleated pad of flexible material woven from fiberglass yarns. Alternate pleats in each pad overlie intervening pleats, thereby forming spaced, parallel, raised surfaces which come into direct contact with the hot product handled by the person wearing the mitt.

Abstract: A hypoallergenic surgeon's glove with an allergenic elastomeric support glove, such as natural latex, has secured to its inner surface by covalent chemical bonds a barrier glove of a nonallergenic elastomer, such as silicone. Sharp angular flexing in the knuckle area, as well as stretching and snapping during donning, does not crack the barrier glove nor delaminate it from the support glove. This hypoallergenic glove requires only about 1/3 the amount of lubricating donning powder in a natural latex glove. In another example, a slip resistant glove, such as silicone, is secured by covalent chemical bonds to an external surface of the support glove.

Abstract: A watersled towed behind a moving boat is steerable from side to side by a rider pulling on or releasing the handle on a single control rope which is attached to a tow rope. The handle is held at various positions by two cleats connected to a raised section of the top deck of the sled between the rider's legs to facilitate proper operation of the sled. The tow rope is attached to the rear of the sled by being passed through an opening in the hull and knotted. The tow rope is held in proximity to the bottom of the sled by passing the rope through a plastic slide configured to travel within a groove extending the width of the sled. The groove is shaped in an arc having a center at the tow rope attachment point and has end closures to prevent the slide from leaving the groove. The control rope is held forward of the tow rope attachment point by a knot in the tow rope.

Abstract: The object of this invention is to provide a releasable hinge for swingable portions such as a cover and bottom of a container or the like.The releasable hinge comprises a pair of spaced apart, laterally flexible spring fingers projecting from one wall of one portion of the container into a blind notch on an opposed wall of another portion of the container. The side surfaces of the notch are arranged and spaced to flex the fingers together until lateral porjections at the ends thereof nest into complimentary recesses in the side surfaces for hingedly coupling the container portions together. When the container portions are rotated about the projections to a maximum open position of the container, back surfaces on the fingers engage and pivot about the blind end of the notch. Further open movement of the container portions causes the projections to be forced out of the recesses for releasing the hinge and preventing damage to the hinge and/or container portions.

Abstract: At the infeed end of a poultry gizzard processing machine are two roller chains comprising a smaller chain riding piggyback on a larger chain. The larger chain has links which extend past either side of the smaller chain and up to define a platform for supporting the gizzard above the smaller chain. The stomach does not rest on this platform but descends between those links to ride on the smaller chain. The smaller chain moves faster than the larger chain to exert a pulling force on the stomach with respect to the gizzard.

One of the blades has a major portion, behind the edge portion, bent at a substantial angle to the edge portion, away from the other blade, so that the gap behind the edge portions is greater than that between the edge portions themselves. Other embodiments include one or both blades each having a major portion comprising two components, one at an angle to the edge portion away from the other blade, the second component bent, at the same angle, to the first, back toward the other blade. As a result the second component is parallel to the edge portion, but displaced further than it is from the other blade. Additionally, an embodiment is provided in which the razor blade support has resilient apparatus to allow independent motion of the blades.

Abstract: Military organizations typically have exacting rules relating to the positioning of insignia on the uniforms of their personnel. Inasmuch as the rules are typically exacting, manual efforts to properly position the insignia are at best difficult. Aids have been developed to assist the personnel in the positioning of uniform insignia. However, known aids tend to be difficult to operate or tend to be expensive. My improved template for positioning insignia on a military uniform includes a center line marked thereon; none, one or more than one edge positioning guidelines marked thereon; one or more horizontal positioning lines marked thereon; and one or more longitudinal, horizontal slots therein. The center line and/or edge positioning guidelines are for aligning the template substantially parallel with respect to the uniform neckline.

Abstract: A portable gyroscopic compass surveying device includes means for rapidly aligning the apparatus with respect to geographic north, the north finder itself being operated apart from the associated theodolite on its own low mount. The transfer of the azimuth reference data is accomplished optically by sighting the theodolite telescope on a retro-reflector associated with the north finder. Because the north finder is physically separated from the theodolite, sightings may be made by the theodolite operator while the undisturbed north seeking operation is in process, significantly shortening the total time of operation at each station.

Abstract: Apparatus used for the directional surveying of deep wells, i.e., 20,000-25,000 feet (6,096 meters-7,620 meters), and which is specifically identified as a gyroscopic directional surveying instrument having a high pressure and a high temperature capability, e.g., 24,000 pounds per square inch (1,632.65 atmospheres) and 450.degree. F. (232.22.degree. C.). While in its fully assembled configuration, the apparatus may be described as being exceptionally long (or at times unwieldy), e.g., 12-16 feet long (3.66 meters-4.88 meters), it is quite remarkable that it does not exceed three inches (76.2 millimeters) in diameter. Therefore, it may readily be lowered into the small diameter steel casing normally defining the walls of these deep wells. In view of its cumbersomeness, it is significant to note that the apparatus may readily be broken-down into upper and lower sub-assemblies when being transported to or from the well site.

Abstract: A veneer block moisturizing vault which has a single upright openable end which is closeable and exposeable through vertical shifting of a rigid unitary door.
