  • Patent number: 4561921
    Abstract: A label applicator device receives a label from a label printer and applies the label to a package by means of a pressure-sensitive adhesive which coats one side of the label. The applicator device includes a label support means which receives a label with the adhesive coated side facing upward. The label support means includes a pair of fingers upon which the label rests. A label transfer nozzle is pivoted about a horizontal axis beneath the label support means into a first position in which it is received between the pair of fingers and engages the printed side of the label by means of a partial vacuum supplied through a vacuum port in the transfer nozzle. The transfer nozzle is then pivoted into a second position in which the adhesive coated side of the label is facing generally downward. The applicator device includes an applicator head which moves downward, removing the label from the transfer nozzle and pressing it into contact with the surface of a package.

  • Patent number: 4534814
    Abstract: A large-scale printhead is made up of rows of styli patterned onto thin glass substrates sandwiched together between rugged support substrates, in which a series of thin glass substrate sections are internally butted one to the other. Fabrication of multiple rows of elements is accomplished by stacking the delicate styli-bearing substrates on an associated rugged substrate. In a preferred embodiment, all glass substrates are utilized, with the transparency of the glass permitting accurate alignment of the styli or nibs. The use of glass substrates also increases the wear resistance of the completed printhead. A specialized bus matrix permits reduction in the width of the substrates carrying the styli, with the bus structure being formed on a single side of the substrate carrying the styli, such that thru-holes need not be provided through the thin substrates.

  • Patent number: 4534827
    Abstract: A cutting tool, preferably in the form of a scalpel, microtome or razor blade is fabricated from single crystal material such as aluminum oxide with a preferential etching process to produce a radius of curvature less than 100 Angstroms on the edge. Depending upon the etchant, the crystallographic orientation of the blank and the resulting different etch rates on blade surfaces, the preferential etching process not only sharpens a preformed edge but also, in one embodiment, produces an opposing edge which meets the sharpened edge at a point, thereby to produce a particularly efficient scalpel blade configuration having two cutting edges converging at a point for plunging and cutting. With respect to the sharpening of the cutting edge, consistent with all other blade forming requirements, the subject blade is made to a maximum sharpness by utilizing a maximum ratio of bevel plane etch rate to edge plane etch rate.

  • Patent number: 4500373
    Abstract: First, a decorative sheet is produced by forming in sequence on a base paper such as titanium paper an ordinary printed layer and a heat-foamable printed layer, respectively with desired patterns. The decorative sheet is then impregnated with a thermosetting resin liquid and dried. The dried impregnated decorative sheet is superposed on a substrate such as a core sheet, and the resulting laminated structure is sandwiched between a pair of heating plates and heated and pressed whereby a thermoset integral structure with the pattern of the foamable printed layer foamed is produced. The entire surface of the integral structure is coated with a solvent to swell the foamed pattern layer and then rubbed to remove the swollen foamed pattern layer and form concavities thereat. The resulting thermoset resin decorative sheet or plate is provided with deep distinct concavities coincident with the pattern of the heat-foamable printed layer as well as a good surface luster.
