Abstract:
A printing medium for the printing of images thereon to form a document by the printer of a standard facsimile machine in a manner which renders the document unreadable to a casual observer. There is a strip of a flexible printing medium receivable by the facsimile machine, and a strip of an obscuring medium adhesively and removably attached to the printing medium in a manner which will allow the obscuring medium to pass through the facsimile machine in combination with the printing medium The adhesive is a permanently tacky base adhesive into which is mixed a dispersion of fine particles, preferably polytetrafluoroethylene spheroids, which have the effect of reducing adhesive build. The preferred base adhesive is a plasticized blend of a vinyl acetate copolymer emulsion and an ethylene-vinyl acetate copolymer emulsion.
Abstract:
A plurality of attachments, each designed for insertion through an object, formed into a relatively tangle-free assembly by being secured together by connectors which do not leave an irregular, snagging stub. Preferably the connectors are more readily severable in torsion than in tension and are formed by the joinder of asymmetric projections.
Abstract:
A method and article providing different images from differing viewing angles. The image side of a lenticular sheet is printed with radiation curable inks and cured (3) using a collimated radiation source located at a viewer position with respect to the lenticular surface (6). Uncured ink is removed from the printed surface, and the resulting clear region (5) of the imaging surface may be processed further in a variety of ways. The clear region may be left unprinted, or printed with a second image different from the first, or a stereoscopic image that combines with its pre-printed mate to form a three dimensional image. The clear region also may be vacuum metallized or chemically plated to form a highly reflective surface.
Abstract:
Variable pitch feed of fasteners by a unitary, single toothed feed member (200). Back-up of the fasteners from the feed position is prevented and the individual fasteners are securely positioned for ejection.
Abstract:
An attachment device (10), method of producing the same, and method of using in which the attachment (10) has a cross bar (12) joined to a head (13-1) by a connector (11-1) forming different angular transitions (t1, t2) with respect to the head (13-1) and cross bar (12). The result is a toggle effect which promotes proper orientation of the cross bar (12) with respect to the connector (11-1) after the cross bar (12) has been inserted into an object.
Abstract:
An antistatic floormat which will overcome commonly encountered phenomena in prior art floormats including unattractive appearance due to the use of dispersed opaque material, unsatisfactory charge dissipation rates and tendency toward fracture due to localized stresses. The floormats consist of flexible laminations (11, 13, 21, 23) of a semiconductive material which resist fracture due to local stresses. The laminations include one or more conductive edge clips (16, 24) or other ion collectors in order to provide efficient charge dissipation paths. A preferred design includes a base construction configured to provide structural support with reduced stress concentrations. An alternative base construction incorporates an array of edge supports (26) with an unbroken central area. The floormats are generally characterized by a transparent or translucent appearance, optionally overlaid with a decorative pattern of semiconductive resin (15, 17) having anti-skid characteristics.
Abstract:
A fastener formed by an elongated member with an apertured tip (16), such as a filamentary string (15) that is attached to a bidirectional locking head (11) with longitudinally opposed openings (C1, C2). The elongated member is inserted into either of the opposed openings (C1, C2) of the head (11), where it is engaged and locked in place by an internal, at least partially circumferentially ring (11r). Once the apertured tip (16) is inserted into the locking head (11), it remains in its locking position even if the filamentary string (15) becomes separated from it as a result, for example, of pilferage.
Abstract:
Une couche de surface métallisée (60) est éloignée de manière sélective (12) d'un substrat électrosensible (10) au moyen d'une impression électrosensible pour exposer une couche intermédiaire à motifs (50). La couche à motifs peut être exposée de manière aléatoire, ou exposée dans des parties prédéterminées. Des fiches, étiquettes ou analogues peuvent être imprimées électriquement avec des codes d'identification uniques, tels que des caractères alpha-numériques imprimés en séries. Ces fiches et étiquettes ne peuvent être copiées par des techniques d'impression conventionnelles. Les couches à motifs (50) peuvent être imprimées en utilisant des encres d'une variété de texture de surface, ce qui se traduit par un effet de gauffrage (Fig. 4) de la couche métallisée. Alternativement, une couche de laque (70) peut être déposée entre la couche à motifs et la surface métallisée pour obtenir un aspect uniforme de la surface métallisée.
Abstract:
An improved release system for heat transferable laminates wherein a transferable substrate (15) which contains a design layer (30) is transferred from a carrier web (2) onto an article such as a plastic bottle or container upon application of heat and pressure. The carrier web (2) includes a nonwax layer (5). The improved release system (5) includes a noncellulosic alkyd thermoset layer portion of the carrier web in contact with and adhered to a nonwax transfer layer portion of the transferable substrate (15). The improved release layer (5) is preferably a melamine modified noncellulosic alkyd which on curing exhibits thermoset properties. The transferable substrate transfers to the article upon application of heat to the carrier while the article contacts the laminate. The transferred substrate on the article is clear and exhibits improved scuff and abrasion resistance. The nonwax layer does not contain wax and may exhibit thermoplastic or thermoset properties.
Abstract:
A method for decoration of paper or plastic sheeting by providing a coating (11) and then embossing the coated substrate (10). The coated sheet is heated to soften the coating (11) by use of a heated platen (32) or heated cylinders (21, 22) and infrared heaters (23). The softened sheet surface is then decorated using an embossing member (31) to provide a diffraction pattern or hologram. The embossment pattern has a lesser depth than the surface roughness of the sheet before embossing.
