  • Patent number: 7455882
    Abstract: A method of applying liquid adhesive to surfaces of components of an electrochemical cell employing a needle valve applicator. The liquid adhesive is applied by dispensing it through a tubular tip connected to a pneumatically actuated needle valve applicator. The method is effective in applying adhesive to narrow width or difficult to reach surfaces of cell components in a precise, consistent and reproducible manner. In a specific application the adhesive can be applied to the narrow recessed step surrounding the terminal portion of the cathode casing of a zinc/air button cell. In such application the cathode casing may typically be rotated at speeds of between about 50 and 1000 revolutions per minute as adhesive is applied thereto from the applicator. The adhesive provides a tight seal between the cathode casing and cathode assembly, thereby preventing leakage of electrolyte from the cell.

    Abstract: Method and device for providing a layer (6) of a coating material on the inner side (2) of a display window (1) for a color display tube. A drop (3) of a suspension of said coating material is deposited on the inner side of the display window, its axis of symmetry (4) being oriented vertically. Then the display window is rotated around said axis of symmetry, and at the same time, said axis is tilted to a horizontal position. The suspension is thereby distributed on the inner side of the display window. An excess of suspension is collected during the rotation in four collection cups (8) arranged at the comers (7) of the display window, whence it is drained off to a central collection cup (10). Finally, the part of the suspension which remains on the display window is dried by infrared radiation (9). As the suspension is drained from the four collection cups to the central collection cup during the rotation, there is no risk that the suspension may drip from the cups onto the display window.

  • Patent number: 4595614
    Abstract: The problem of distortion in the shape of the vessel by simultaneous heating and rolling at high temperatures is remedied by adding shape retaining, firing rings to the vessel. Firing rings are rings spacedly attached to the periphery of the vessel to maintain the vessel out of direct contact with the rotating means while the vessel is heated to glass firing temperatures. Usually two rings are used, however, more than two may be utilized if desired. The rings extend a sufficient distance from the vessel side so that distortion of the vessel during glassing and rolling is prevented. Typically, the rings extend outward from the vessel wall a distance of from about 2 inches to about 18 inches and, more preferably, from about 4 inches to about 12 inches. The firing rings are loose fitted, or mounted, over the vessel exterior and preferably are positioned near or at the knuckle radius or radii of the vessel.

  • Patent number: 4262624
    Abstract: A method of forming a puncture preventing layer on an inner surface of a pneumatic tire including the steps of extruding sealing material and pulverizing the extruded sealing material into fine particles for coating the inner surface with a layer of the sealing material under pressure through action of centrifugal force. For effecting the above described method in an efficient manner, there is also provided a puncture preventing layer forming apparatus which includes arrangements for holding the tire, extruding the sealing material, and pulverizing the extruded sealing material so as to be coated onto the inner surface of the tire through the action of centrifugal force.

  • Patent number: 4096295
    Abstract: A plurality of articles such as sheets or lenses are simultaneously and uniformly coated by first placing them in vertical spaced relationship with respect to each other within a tank having a quantity of fluid coating material therein. The coating material flows across the surfaces to be coated. Thereafter, the sheets are lifted out of the tank into an elongated chamber above the tank in which they are spun about their vertical axes. Excess coating material is thus driven off the surfaces to be coated. Means to recover, clean, replenish and remove bubbles from the coating material are disclosed.

  • Patent number: 4052494
    Abstract: A method and apparatus utilized in forming a hemispherical shape from a cast thermoplastic acrylic resin sheet or the like, dyeing the inside surface of the hemisphere to provide a uniform color density or a color density variation increasing from light to dark from the horizon to the zenith point of the hemisphere, heating the hemisphere to its forming temperature, causing it to revert to a flat sheet, and reverse forming the hemisphere to have the dyed surface on the outside.
