Abstract: There is disclosed a work clamp and tool guide assembly which comprises a base plate, a crossbar secured to, and extending transversely across, the undersurface of the base plate, first and second upright posts, one each at opposite ends of the crossbar, a guide rail with distal apertures received over the first and second upright posts and locks to fixedly secure the guide rail at preselected heights. The workpiece is clamped between the guide rail and the base plate and can be oriented for right angle cuts by a fence which extends along at least one side of the base plate. A work tool such as a router, saw and the like can be guided across the surface of the workpiece with its edge against the guide rail.

Abstract: There is disclosed a liquid gel composition useful for incorporation in thermoplastic and thermosetting resins. The liquid gel comprises a liquid mixture of certain hydroxyalkyl fatty amines or fatty imidazolium quaternaries which is gelled by an organophilic, expanding lattice clay that is ion exchanged with alkyl ammonium ions. The clay is employed at a sufficient concentration to form a stable gel and is milled into the liquid vehicle to form a gel of a suitable viscosity to permit it to be added to the resin with metering injection equipment. The composition when used at low concentrations in resins enhances the physical properties of the resins by imparting a permanent anti-static characteristic to the resins and by significantly decreasing their brittleness, thereby increasing elongation, impact and tensile strengths of the resins.

Abstract: There is disclosed a hand cover such as a glove or mitten having at least a portion of its frontal surface bearing an outwardly exposed thin pad of reticulated plastic foam. Reticulated plastic foam is a non-capillary, open skeletal fibrous structure that is obtained from open cell plastic foam by destroying a substantial quantity of the cell walls with a suitable treatment, leaving an intertwined skeletal fibrous structure. In various embodiments, the thin pad of reticulated foam overlies the palm, the frontal surfaces of the fingers, the entire frontal surface of the hand, or the entire hand. The reticulated foam provides a vastly superior grip to objects such as tools, bats, rackets and the like.

Abstract: There is disclosed a stable thixotropic suspension of water insoluble animal feed nutrients in an aqueous sugar solution. The method comprises incorporating an ammonium phosphate, sulfate or mixture in an aqueous sugar solution in a sufficient quantity to form a gel, controlling the pH of the gel to a value from about 6.5 to about 7.5 and adjusting the water content of the mixture to provide a viscosity to the product from about 4,000 to about 10,000 centipoises. The resultant gel is an excellent carrier for the suspension of water insoluble nutrients such as, calcium carbonate, calcium sulfate, or insoluble drugs such as monisan. The gel provides a very stable suspension of the water insoluble nutrients, providing shelf life stability in excess of 12 weeks over a wide range of temperature. High temperature stability of the suspension can be further enhanced by including in the supplement a dispersing agent such as gellatinized starch, an alkali metal alginate or a montmorillonite or kaolin clay.

Abstract: There is disclosed a socket retaining ring for use with power driven sockets to fasten the sockets to the plug of the drive tool. The retaining ring comprises a molded, one-piece elastomeric ring having an integral, diametric pin extending from one side substantially across the span of the ring. The retaining ring is used with sockets which have a pinned interconnection to the plug of the drive tool by inserting the flexible diametric pin of the ring into the retaining hole and seating the ring in the peripheral groove about the socket.

Abstract: There is disclosed a hollow form building block useful for toys as a constructional block for play houses, forts, and the like, which is formed of inexpensive sheet material such as corrugated cardboard. The block element is a hollow-form, polyhedron that is provided with end walls, one of which has a polygonal aperture and the other of which has a coacting polygonal raised rim that is formed by folded tabs cut from the end wall and coacting tabs folded from an underlying end wall. The raised rim coacts with the apertures of other block elements to provide element-to-element interconnecting means and the raised rim also functions to secure the hollow-form block structure of the assembled, folded block element.

Abstract: There is disclosed a method for the elimination of the chief impurities in aluminum dross tailings. The dross tailings, which are chiefly particles of aluminum oxide, are suspended in an aqueous slurry and the slurry is heated to a temperature from 185.degree.-225.degree. F. and maintained under liquification pressures and sufficient agitation to insure particle-to-particle attrition that removes an aluminum hydroxide coating which would otherwise inhibit the reaction. The reaction rate is accelerated by chemical and physical additives that can be optionally added to the slurry such as trace quantities of caustic, which serves as a source of hydroxyl ligands to increase the solubility of aluminum hydroxide and/or refractory particles such as ceramic spheres which increase the attrition. Other contaminants present in the dross tailings include aluminum nitride, which is decomposed to aluminum oxide and ammonia, and aluminum carbide which is decomposed to aluminum oxide and methane.

Abstract: There is disclosed a method for the imprinting and decorating rotomolded products. The method comprises the application to the interior surfaces of the mold of a viscous suspension of pigment in a preselected pattern. The suspension is applied to the mold surface in an oil carrier using a vegetable, animal or mineral oil that is inert under the molding conditions and that has a sufficient viscosity at the molding conditions to maintain the film on the mold surfaces. The pattern of the pigment suspension is applied by spraying, brushing, screen printing and the like and, after its application, the conventional rotomolding can be practiced. In this method, the powdered plastic, typically high density polyethylene, in powder form is charged to the mold, the mold is closed and placed in an oven heated to from 500.degree. F. to about 800.degree. F.

Abstract: There is disclosed a composition useful as a solder mask coating for use in the manufacture of printed circuit boards and the like which comprises a mixture of an alkyd resin and an alkylated amino resin, a minor quantity of a hydrocarbon resin, an inorganic filler derived from sedimentary shale of a particular origin, and sufficient organic solvent to provide a working viscosity suitable for silk-screening applications. The invention comprises also the use of a preferred and particular inorganic filler known as Panamint Earth.

Abstract: There is disclosed a stereoscopic viewing system utilizing one or two prisms to direct the line of sight from a viewer's eyes to each of a pair of stereoscopic images. The single lens sytem employs different occluded angles between the prism faces and the facing image planes to avoid lateral distortion of the images. In the preferred embodiment, the prisms have a plano face and an opposite face bearing a plurality of equally-spaced, straight and parallel V-grooves, forming a plurality of equally-spaced, longitudinal triangular prisms therebetween. The preferred viewing system employs, in the simplest embodiment, one of these prisms mounted with its grooved face at an occluded angle of from 40.degree. to about 60.degree. to one of a pair of stereoscopic images. The second stereoscopic image is mounted on a planar imaging surface at an occluded angle of from 2.degree. to about 15.degree. to the plano face of the prism.

Abstract: There is disclosed a solid animal feed supplement block packaged in block form with structural members that subdivide the block. The block has a reduced consumption rate that results from the structural members within the block. The preferred members comprise partitions formed of corregated cardboard which subdivide the block into a plurality of cells. The animal feed supplement can contain a drug and the partitions can provide a convenient measure of the drug dosage, preferably by providing a plurality of solid blocks or cubes each of which provides a premeasured dosage, e.g., a daily dosage for a single animal.
