Abstract: A decorative laminate and method of transferring designs onto articles. The laminate is formed of a transfer substrate affixed to a support member. The transfer substrate is composed of a protective layer, an ink layer, and a nonwax-based adhesive/release layer. The adhesive/release layer is in direct contact with the support member and use of a wax layer intermediate the adhesive/release layer and the support is excluded. Optionally, a barrier layer is provided between the adhesive/release layer and the ink layer. In many applications the protective coating layer may be omitted. The laminate is applied to an article using a heated silicone rubber transfer pad to which the transfer substrate adheres during the transfer process.

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.

Abstract: A thermal ink transfer laminate wherein an ink design is transferred from a carrier support to an article, typically paper, by application of a thermal printing element, e.g. of the dot matrix type, to the nontransfer side of the carrier. The thermal ink transfer laminate is composed of a carrier support of paper or plastic film overcoated on one side with a heat sensitive transfer substrate. The heat sensitive transfer substrate contains an ink which preferably includes a coloring agent formed of a dye dispersed in an unsaturated fatty acid medium. A separate release layer may be included between the ink and carrier. The coloring agent facilitates attainment of a drastic drop in melt viscosity of the transfer laminate during thermal transfer onto a receiving article. The degree of transfer attained is virtually complete resulting in a transferred image of exceedingly high image clarity and definition when employing the thermal printing element.

The improved release coating incorporates a tackifying resin in a wax base. The wax base includes a montan wax and a crystalline wax such as paraffin wax. The wax base may also include a microcrystalline wax component. The preferred tackifying resin is selected from the polyterpene class.

Abstract: A fastener formed by an elongated member with an apertured tip, such as a filamentary string, that is attached to a bi-directional locking head with longitudinally opposed openings. The elongated member is inserted into either of the opposed openings of the head, where it is engaged and locked in place by an internal, at least partially circumferential ring. Once the apertured tip is inserted into the locking head it remains in its locking position even if the filamentary string becomes separated from it as a result, for example, of pilferage.

Abstract: An improved release formulation for use in a heat transferable laminate wherein an ink design image is transferred from a carrier support to an article by application of heat to the carrier support. On transfer the release splits from the carrier and forms a protective coating over the transfered design. The improved release is coated onto the carrier as a solvent based-wax release. The release coating is then dried to evaporate the solvent contained therein. The improved release has the property that its constituents remain in solution down to temperatures approaching ambient temperature. Upon transfer, the release forms a protective coat which may be subjected to hot water. The improved release contains a montan wax, a rosin ester or hydrocarbon resin, a solvent, and ethylene-vinyl acetate copolymer having a low vinyl acetate content.

Abstract: Coating methods and compositions for products and transfer media, such as carbon papers, in which the major constituent is a filler such as clay, titanium dioxide, calcium carbonate, or the like. The filler replaces a substantial amount of, and extends, the wax or wax-like material which ordinarily forms the principal part of a transfer coating, while providing improved transfer characteristics. The coating is prepared as a dispersion of the filler or extender, with wax or a wax-like material and colorant, in a low viscosity medium such as water. The coating can thereafter be applied to a substrate to provide a desired product by using suitable equipment, such as a trailing blade coater, which may be incorporated into a paper making machine or used separately.

Abstract: Dielectric sealing of porous anodized aluminum, in which moisture in the pores of the oxide coating formed by hardcoat anodizing is removed, and the porous anodized surface then impregnated with a dielectric wax. Suitable wax sealants include Carnauba and Montan waxes. The anodized member is preliminarily heated to a temperature in the range 120.degree.-180.degree. C. in order to drive off moisture and other substances from the pores. This heating process may be continued for the purposes of impregnating the pores with the wax sealant, which is applied as a hot melt. Alternatively, the preliminary dehydration is achieved simply by heating the member to the impregnating temperature, with no separate dehydration stage. Any excess material remaining on the member's surface is removed. The resulting product has excellent resistivity and dielectric properties, and maintains these properties at elevated humidities.

Abstract: Thermal imprinting of substrates, for example one or more surfaces of multi-dimensional objects, using a heat transfer film formed by a carrier and a release layer of pigmented, low molecular weight polyolefin. The imprint is made by bringing the transfer layer into contact with the surface of an object and applying heat. This releases the transfer layer to the surface being imprinted. When the transfer layer is required to have any significant thickness, it desirably includes a low melting point wax or resin to provide flexibility. The release characteristic can be improved by the inclusion of a further crystalline wax layer between the transfer layer and the carrier.

Abstract: Apparatus for heat transfer labelling of articles using a resilient pad maintained at elevated temperatures. Decorative laminates affixed to a support member such as a web are fed to a heated platen. A resilient pad consisting of a silicone elastomer is pressed against the laminate at the heated platen, whereby the laminate adheres to the pad when it retracts from the platen. The heated pad is then pressed against an article to be labelled, to which the transfer substrate adheres in preference to the pad surface. The resilient pad is typically heated to a temperature above ambient temperature but lower than that of the heated platen. The pad is heated by repetitive contact with the platen, and additionally by an independent heater. The pad may include one or more interior heating elements, or an exterior radiant heater located adjacent the pad during periods between label transfers. This apparatus is well suited to the labelling of articles of a wide variety of sizes, shapes, and materials.

Abstract: An electrosensitive security laminate including a magnetic layer providing a magnetically encodable substrate. The laminate includes a base layer such as paper, a magnetic layer deposited on the base layer, and a vapor deposited metallic layer either over the magnetic layer or the opposite face of the base layer. Additional security may be achieved by including a decorative intermediate layer having a visibly nonuniform pattern. The user may detect a magnetically encoded pattern using a device which forms a visible pattern in accordance with any magnetic field adjacent the laminate. The patterned intermediate layer where included may be selectively exposed by electrically imprinting the metallized layer, thereby exposing a background pattern within any inscribed indicia.
