  • Apparatus for continuous molding
    Patent number: 4462784
    Abstract: Continuous molding of objects using a rotatable molding wheel with peripheral orifices in accordance with the objects to be molded. Plastic is extruded upon the periphery of the wheel and a knife in substantially eliptical contact is used to skive film from the objects being molded. Following molding, selected portions of the objects can be selectively distended. Suitable distention can be achieved using diverging sprocket wheels. When the continuously molded objects are fasteners with filament-like portions, the diverging sprocket wheels can be used to stretch the filamentary portions and reorient their molecules.

  • Silicone pressure sensitive adhesive and uses
    Patent number: 4460371
    Abstract: Pressure sensitive adhesive having favorable adhesive, shear, liquid permeability, and release characteristics. The adhesive is a crosslinked polymerization product of a methyl/phenyl siloxane gum, dimethyl siloxane gum and a polysiloxane resin. The resulting product provides suitable adhesion to a large number of surfaces and has particular utility as an adhesive between plastic film and human skin, especially for use with transdermal therapeutic devices. The adhesive characteristic mitigates damage to underlying surfaces such as human skin tissue during adhesive removal.

  • Bottle cooler
    Patent number: 4457079
    Abstract: Apparatus for convectively cooling bottles and the like in a heat transfer decorator. Bottles travel on an underlying conveyor where they are subjected to descending air streams issuing from a plenum chamber. Refrigerated or room temperature air is directed from the plenum chamber by a series of fans, and routed through a honeycomb flow straightener which reduces the helical turbulence of the air streams. The air streams pass between nozzle plates which further enhance the flow uniformity.

  • White electrosensitive paper
    Patent number: 4456632
    Abstract: Method and apparatus for fabricating electrosensitive paper with a white finish. The paper comprises a base layer of paper, a solvent-based resin coating, and a thin surface layer of aluminum, optionally including a white overcoat. A mixture of solvents may be employed having different evaporation rates, providing a white appearance of the metallized layer. The solvent mixture may include a relatively volatile true solvent, and a less volatile diluent. After application of the resin coating in solution to the paper base, the solvents may be evaporated using a three-stage drying process in which the first stage involves an elevated temperature with turbulent air flow.

  • Apparatus for handling oval articles
    Patent number: 4456422
    Abstract: Apparatus for handling articles of oval cross section during silk screen imprinting and the like. An oval article is engaged at top and bottom by carriages, each slidingly mounted along a diameter of a rotating support. The article is conveyed past a screen printing station to imprint a first face, then shifted across the support diameter. The second face of the article is then transported past the screen for imprinting, followed by release of the article for further processing. The timing of the carriage shift is controlled by a pneumatic assembly, and is limited by a pair of adjustable stops according to the radius of curvature of the article.

  • Web transport system with electro-optical label detection
    Patent number: 4452659
    Abstract: A label carrier web transport for use in heat transfer decorators and the like, in which labels are optically registered to control web transport. A timing assembly coordinates the rotation of a cam shaft with the actuation and deactuation of clutch and brake assemblies within a metering roll. An optical scanner trained on the web registers a predetermined contrast location to actuate the brake and deactuate the clutch, subject to the presence of an enabling signal from the timing assembly. The metering roll, in combination with a reciprocating label shuttle, provides intermittent web motion to achieve controlled label advance. An alternative label transport system incorporates a capstan web drive in lieu of the metering roll, with a microprocessor to control various machine functions including intermittent web transport.

  • Distortion and chemically resistant heat transfer materials
    Patent number: 4426422
    Abstract: Distortion and chemically resistant heat transfer materials formed by a mixture of at least two interspersed polymers. One of the polymers is a film-forming, multi-aromatic ring condensation product, preferably a saturated aromatic, acid-based polyester. This polymer is reinforced by a second polymer which preferably contains bulky ring structures, such as polymerized rosin esters, but may be essentially linear, for example an ethylene-vinyl acetate copolymer. The materials may be used as a protective and brightener coating for labels, which are heat activated to transfer them from a carrier to a final substrate such as the face of a package. The labels thus coated exhibit improved resistance to adverse chemicals such as alcohols, oils and detergents. The materials may also be used to provide distortion and chemically resistant inks, and distortion and chemically resistant adhesives.

  • Dispensing of fasteners with a pivoted and disengageable feed mechanism
    Patent number: 4416407
    Abstract: Dispensing of fasteners by a device which receives an assemblage of the fasteners and is able to expel them individually through, for example, a slotted hollow needle. The dispensed fasteners can be used generally in the attachment of items to one another and, in particular, for the labeling of textile goods and the like with information bearing tags. The device includes a trigger operated feed mechanism and a simultaneously operable expulsion mechanism. Both mechanisms are controlled by the tip of a lever which is proportioned and disposed in the device to execute linear motion. The feed mechanism is disengageable from the remainder of the device to permit clearance of the inserted assemblage or the removal of jams. The feed mechanism additionally is operated by a planar pawl having a tooth that extends into contact with indentations on the periphery of a feed wheel.

  • Webbed harnessing device
    Patent number: RE31541
    Abstract: A harnessing device formed by a locking head and an attached webbed strap. The head contains oppositely positioned locking tangs in a guide channel that receives the strap after encirclement of items to be harnessed. The tangs engage abutments of the webbed strap for adjustable retention of the harnessed items. The strap is advantageously molded of a stretch reorientable material. Stretching produces a relatively thin and strengthened web which resists penetration by the locking tangs and reduces the possibility of failure by fracture or reverse rotation. The inclusion of the relatively thin web also promotes homogeneity during molding and avoids imperfections that can cause failure in other types of straps.
