  • Patent number: 4354815
    Abstract: An apparatus and method for the automatic, rapid and continuous preparation of generally friable or fragile ready-to-eat food product bacon analog strips of predetermined configuration, simulating natural, cooked bacon, wherein a slab or bulk material of the food product is sliced by a cutting device into individual strips basically having the dimensions of sliced natural bacon strips, and conducted by means of a first endless conveyor arrangement from the cutting device towards a cooking installation. Ahead of the cooking installation, a second endless conveyor mounts a series of strip-engaging members adapted to sequentially contact the sliced strips and to conduct the strips from the first endless conveyor arrangement onto and along guide rod members which extend into and through the cooking installation.

  • Patent number: 4352775
    Abstract: A blank is formed out of plasticizable, heated plastic by means of an extruding-type material supply head. A somewhat lenticular profiling of the blank is obtained by appropriately controlling a closing member of the material supply head, which is built as a valve cone. When the closing member is closed off against the lower edge of a tube part of the material supply head, the blank is pinched off from the material supply. A flow of air emerging from a ring nozzle serves to ensure complete severance of the blank from the material supply head. After that has been accomplished, the blank enters an open shaping cavity of a die by free fall. By further movement of the die, which is located on a rotary table, the die removes itself from the permanently located material supply head, so that the blank lying in the cavity can be pressed into a molded article by a stamp. Cooling off too much in certain locations on the blank is prevented by the free fall of the blank into the shaping cavity.

  • Patent number: 4351508
    Abstract: A reusable plugging dam for bowling balls is provided for retaining suitable filling compound until set or hard in and somewhat above a finger hole of the ball to be filled such that sufficient filling compound is present to allow for shrinkage during curing or hardening, and be ground and polished to conform to the spherical shape of the ball. The dam includes a body and a suction structure for securing the body to the ball and prevent seepage of the filling compound between the ball and the dam. The body has a port therethrough so as to allow filling of the finger hole with filling compound. Dams are provided for single or multiple finger holes. In addition a dam is provided for use in conjunction with another dam and in particular for filling horizontally aligned holes, this dam having a cover to retain the filling compound in the dam.

  • Patent number: 4350498
    Abstract: The present invention relates to abrasive articles such as grinding wheels which employ organic binders and are improved by the use of certain oils or with the use of long chain aliphalic monhydroxy alcohols or long chain alkylated phenols alone or mixed with particular oils as dust depressants or dampening agents used with the conventional plasticizers. These dampening agents prevent "balling", minimize dusting and produce a more durable abrasive article.

  • Patent number: 4347210
    Abstract: A method of forging spinel into complex shapes in which a spinel plate is placed in a mold while the spinel plate is heated, in an atmosphere of helium, to a temperature below its melting point and above its solid two phases transition point that allows plastic deformation to take place. Forging stresses well above the yield point of the spinel are applied to the plate by the mold to reduce the forging time.

  • Patent number: 4342719
    Abstract: Method for making extruded bricks having a textured handmade appearing face designed to form on outer building wall surface, comprising the steps of feeding a column of brick-forming clay mix into a progressively narrowing inlet funnel portion of a brick extruding die, progressively constricting the clay mix column while feeding the same from said inlet funnel portion through a die throat section of the extruding die of horizontally elongated rectangular cross-section defined by downstream converging upper, lower and side boundary surfaces to shape the clay mix column to a rectangular cross-section whose width dimension perpendicular to said face slightly exceeds the desired ultimate brick width, disrupting the clay column in said die throat section at a subsurface location space near and below the uppermost boundary surface of the die throat section along a plane substantially spanning the transverse extent of the die throat section by pressurized downsteam-directed liquid jets internally disrupting the clay

  • Patent number: 4340348
    Abstract: A method and apparatus provided for manufacturing elastomer gloves having percentage elongation of at least 300%. In order to prevent excess deposits of the polymer latex in the areas of the tips of the fingers and the webs between the fingers when the hand-shaped molds are coated, by dipping, with the polymer, the surfaces of the mold in these areas are formed as non-rounded, non-horizontal inclined surfaces which join at an apex and define an included angle therebetween. This arrangement prevents the pooling of the polymer latex in the areas in question, this pooling being the cause of the excess deposits and being characteristic of prior molds of this general type. In order to provide sufficient coagulant around the sharp corners formed in the areas of the tips of the fingers and the webs between the fingers so as to provide sufficient coating in those areas, it is necessary to use a heated mold and to provide sufficient dwell time and withdrawal time for the mold from the coating baths during the process.

  • Patent number: 4336211
    Abstract: The invention provides a novel method for obtaining a shaped article of a vinyl chloride-based resin which is markedly insusceptible to the undesirable phenomenon of exudation or bleeding of the plasticizer and other additive ingredients contained therein on to the surface of the article. The method comprises formulating the resin composition for the fabrication of the shaped article with an epoxy compound containing, preferably, at least 2% by weight of the oxirane oxygen in the molecule in an amount of at least 0.05% by weight based on the vinyl chloride-based resin and irradiating the shaped article with ultraviolet light having a substantial energy distribution in the wavelength region of 200 nm or shorter. The shaped article obtained by the inventive method is remarkably insusceptible to the plasticizer bleeding even after prolonged outdoor exposure or irradiation with ultraviolet light having wavelengths longer than 290 nm.
