  • Patent number: 4887816
    Abstract: A lottery apparatus comprising a receptacle from which lottery balls can pass into a mixing chamber. A screw conveyor in the form of a rotatable tube with an internal helical baffle extends horizontally from the mixing chamber to a discharge chamber. The end of the screw conveyor in the mixing chamber has a scoop attached thereto which serves to agitate the lottery balls in the mixing chamber and to feed one ball to the conveyor with each rotation of the conveyor. The rotatable tube is transparent so that progress of each lottery ball therethrough can be watched. Clear plastics are preferred materials for most apparatus parts. A manual crank or an electric motor is used to rotate the screw conveyor.

  • Patent number: 4873273
    Abstract: A thermosetting resin composition particularly suitable for surface coatings, including metals, paper and paperboard, and especially those papers subsequently converted into shaped paperboard products, e.g. paper plates and folded cartons, with a high gloss, water and oil resistant surface coating. The composition is suitable also as both an adhesive and coating in metallizing substrates by the transfer of metallic particles from a transfer agent to the substrate. When formulated without solvents or dispersants it is suitable for use as a casting composition or as a molding material. The composition comprises a polymer or copolymer containing carboxylic acid groups; an epoxy compound containing an average of more than one epoxide group per molecule; an ammonium or phosphonium base or salt thereof; and a monomeric carboxylic acid or inorganic acid which extends the useful working life of the composition and imparts a superior glass to the surface of the finished product.

  • Patent number: 4843678
    Abstract: A novel caster pad attachable to the bottom of a receptacle and adapted to receive and hold a replaceable caster assembly has a rectangular base with a flange at each of its four edges. A pair of opposite flanges have a hole near each end of the opposite flanges, the holes in one flange being in alignment with the holes in the opposite flange. A U-shaped rod has arms which can enter the holes of one flange and extend out of the holes of the opposite flange so that the plate of a caster assembly can be captured between the base of the caster pad and the arms of the U-shaped rod. Locking devices are applied to the end of one or both arms to lock the U-shaped rod in place with its arms extending through the aligned holes.

  • Patent number: 4834546
    Abstract: The invention is directed to a method of and a system for mixing batches of a flowable medium, especially of hydrocarbons used as base materials for said media and of additives to be admixed thereto. In the mixing operation, the base materials and optionally additives are weighed in a primary weighing section capable of holding a complete batch to form the base medium. Independently thereof, additives, amounting to minor fractions of the batch, are weighed out in at least one precision weighing section. The weighed-out additive fractions are then admixed to the weighed-out base medium.

  • Patent number: 4822452
    Abstract: A method for forming a fibrous web by wet-laying fibers on paper-making equipment, the web comprising staple length natural or synthetic fibers and wood cellulose paper-making fibers wherein a water furnish of the fibers is made up with an associative thickener in the absence of a conventional surfactant. A preferred associative thickener for use with hydrophobic fibers is a urethane block copolymer having a polyethylene glycol backbone, the associative thickener acting as both surfactant and thickener. With predominately cellulosic fibers, i.e. conventional wood cellulose fibers, or a mixture of conventional and contorted wood fibers, and synthetic cellulosic fibers, such as rayon, a hydroxyethyl cellulose having a long alkyl side chain is preferred. Excellent consistency of the water and fiber dispersion is obtained at relatively low viscosity with rapid drainage of water from the wire and uniform formation of the web.
