Abstract: The improved impulse heat generation and sealer apparatus of the present invention comprises preferably a metallic heat sink block bearing a shallow groove on the face surface thereof. The shallow groove is lined with a thin layer of an electrical insulator/heat conductor and the groove is filled with a preferably metallic electrically conductive material to form a smooth and preferably co-planar surface with the face surface of the metallic block. This smooth surface is coated with a thin layer of a release coating. A resilient mating surface is provided in preferred embodiments for reciprocating motion, whereby an electrical impulse rapidly generates heat in the groove filler material to bond together sheets of a polymeric material disposed between the mating surfaces, and the heat is rapidly dissipated to prevent damage to the sealed sheets. In other embodiments, the heat sink structure may be utilized in heat radiators or any other fast cycling heat exchanger.

Abstract: An improved package for containing a slab of sliced comestible product disposed in overlapping array, the package including a backing board having rounded and upwardly disposed corners with a smooth radius and lateral edges all of which are covered by the overlapping array of sliced comestible, and a film of transparent flexible material snugly enclosing the backing board and the overlapping array of sliced comestible product with the overlapping array of sliced comestible product interveningly cooperating with the lateral edges and rounded corners of the backing board to prevent puncturing of the film by the lateral edges and upwardly extending rounded corners of the backing board.

Abstract: In one preferred embodiment, a lid for a polygonal container, such lid having a polygonal top panel corresponding in shape and size to the opening at the top of the polygonal container, such top panel hingedly connected to a plurality of lid side panels at each of the sides of the polygonal top panel, each lid side panel disposable downwardly to abut the lid side panels in substantially contacting relationship at the edge portions thereof, each lid side panel having a securement panel hingedly connected at the lower edge thereof, and a plurality of locking panels hingedly connected to the lid side panels and having a locking protrusion at the upper edge thereof for engaging with the securement panel of the lid side panel.

Abstract: Polygonal containers of the present invention include a container sides assembly and a container bottom assembly which are adapted for interlocking engagement.The container sides assembly has a plurality of generally rectangular side panels hingedly interconnected to form an enclosure defining the sides of the polygonal container.A plurality of lower edge flaps are hingedly connected to the lower edge of the rectangular side panels and are adapted for folding upwardly and inside the enclosure to interlockingly receive corresponding elements from the container bottom assembly.The container bottom assembly has a polygonal bottom panel having sides equal in number to the rectangular side panels and are of such a size to fit snugly within the container sides assembly when in assembled configuration for forming the container bottom.

Abstract: An improved rustproofing composition for application to metal panels of motor vehicle bodies for prevention of rust and corrosion of same, comprising polychloroprene polymer latex solids dispersed in an aqueous medium, surface active agents, pigments, freeze point reduction agents, rheological control agents, bacteriostatic agents, pH-control agents, and corrosion inhibitors.

Abstract: For motion picture film projectors generally of the type having a projection slot on the housing thereof, the improvement comprising an inwardly sloped dynamic frusto-conical film guide surface on the film guide roller, the frusto-conical film guide surface having an axis of rotation congruent with that of the film guide roller and disposed at the free end thereof and sloping toward the journaled end thereof to form an inwardly sloped dynamic film guide surface; and an outwardly sloped dynamic frusto-conical film guide surface disposed on each film threading roller, each such outwardly sloped dynamic frusto-conical film guide surface being disposed to slope away from the journaled end of the film threading roller, whereby upon introduction of the film onto the outwardly sloped dynamic frusto-conical film threading surface, the film will tend to climb the surface in a direction toward the journaled end of the film threading roller to bias the film into the projection slot and to maintain the film therein durin

Abstract: The present invention is a method of treating sea or land carbonaceous ore or reconstituted, formerly carbonaceous ore to recover therefrom noble metal values. If sea ore is used, noble metal containing composite organic material is first separated from any shells or sand that may be present. Flotation techniques are then utilized to form a carbonaceous concentrate, which is next mixed with a strong oxidizing agent. The mixture may either be heated to provide autogenously ignition or ignition may alternatively be accomplished by compounding the mixture into electrodes and using electric arc. If stoichiometric quantities of the oxidizing agent are used, the oxidation-reduction reaction, which consumes all carbon present, is of sufficient energy to drive the noble metals and/or their compounds into the vapor phase forming a particulate plasma, from which the elemental metals or their compounds may be condensed and/or precipitated.

Abstract: The present invention generally concerns hobby finishing tools. More specifically, the present invention is directed to a multi-purpose hobby finishing apparatus for cutting, drilling, grinding and finishing hobby materials, such as especially glass, and also plastics, ceramics, and wood, which materials may be used in making useful and decorative lamps, candleholders, tumblers, vases, ashtrays and the like.

Abstract: A method of freeze treating mayonnaise and mayonnaise-containing products, such as egg, chicken, or ham salad, in which the frozen product may be satisfactorily stored and upon thawing maintains the physical and chemical characteristics of its pre-frozen state, which method comprises immersing mayonnaise or a mayonnaise-containing product in an inert liquid which is maintained at a temperature of between approximately -50.degree.F. and 0.degree.F., maintaining the product therein until completely frozen and removing the product and storing it at temperatures of between approximately -50.degree.F. and 0.degree.F.

Abstract: A method of freeze treating a cooked egg product which does not result in substantial changes in the physical or chemical characteristics of the later thawed product, which method comprises immersing and retaining the cooked egg product in a bath of a liquid freezing medium for a relatively short predetermined period while the freezing medium is held at a temperature within the range of approximately 0.degree.F to approximately -325.degree.F.
