Abstract:
Apparatus for printing labels onto circular discs of predetermined diameter includes a linear printhead having a length equal to at least the diameter of the discs to be printed. A carrier has a planar surface with a circular recess into which a compact disc can be tightly inserted. The recess is of a depth substantially equal to the thickness of the disc to be printed, whereby the planar surface and a surface of an inserted disc form a substantially flat surface. The carrier is formed of a substrate and a member which defines the outer boundary of the recess. The substrate is at least partially formed of an elastic material having a compliance selected so as to provide a pressure on the printhead optimal for dye transfer. A second rigid member fits into a center hole in the inserted compact disc.
Abstract:
A resistive thermal printer has a platen drive mechanism which includes (1) a thermal printhead having an array of selectively-activatable thermal elements and (2) a rotatably-driven platen roller opposed to the printhead and forming a nip with the printhead through which a receiver medium is driven by the platen roller while the thermal elements are selectively activated. The platen roller has an inner core and an outer sleeve formed of a heat shrunk material. The platen roller includes a compliant layer below the outer sleeve.
Abstract:
An ink jet printing ink composition is disclosed for use with an ink jet printing apparatus comprising a printhead, an ink delivery system adapted to provide the ink to the printhead, and a sensor associated with the ink delivery system adapted to produce a signal which is characteristic of the concentration of a label material in a printing ink, where said signal is used to indicate the appropriateness of using a particular printing ink. The ink composition comprises a carrier, a colorant, and a predetermined concentration of a distinct label material, the weight ratio of the label material to the colorant being less than 1. The label material may be easily detected by a sensor associated with the ink delivery system.

Abstract:
An improved spectrally sensitized ultrathin tabular grain emulsion is disclosed in which tabular grains (a) having {111} major faces, (b) containing greater than 70 mole percent bromide and at least 0.25 mole percent iodide, based on silver, (c) accounting for greater than 90 percent of total grain projected area, (d) exhibiting an average equivalent circular diameter of at least 0.7 .mu.m, (e) exhibiting an average thickness of less than 0.07 .mu.m, and (f) having latent image forming chemical sensitization sites on the surfaces of the tabular grains, are spectrally sensitized. The speed-granularity relationship of the emulsion is improved by employing in forming the surface chemical sensitization sites at least one silver salt epitaxially located on tabular grain surface sites that contain increased iodide concentrations.A photographic element is disclosed comprised of a support, a first silver halide emulsion layer coated on the support and sensitized to produce a photographic record when exposed to specular light within the minus blue visible wavelength region of from 500 to 700 nm, a second silver halide emulsion layer capable of producing a second photographic record coated over the first silver halide emulsion layer to receive specular minus blue light intended for the exposure of the first silver halide emulsion layer, the second silver halide emulsion layer being capable of acting as a transmission medium for the delivery of at least a portion of the minus blue light intended for the exposure of the first silver halide emulsion layer in the form of specular light, wherein the second silver halide emulsion layer is comprised of the improved spectrally sensitized ultrathin tabular grain emulsion of the invention.The ultrathin tabular grain emulsions with silver salt epitaxy chemical sensitization have been observed to produce larger than expected speed increases, to produce higher than expected contrasts, to be unexpectedly specularly transmissive and therefore compatible with forming sharp photographic images in underlying emulsion layers, to exhibit a higher percentage of total light absorption in the wavelength region of maximum absorption by the spectral sensitizing dye or dyes employed, and to exhibit a surprising tolerance of inadvertent manufacturing variances.
Abstract:
A process is disclosed for the precipitation of a silver halide emulsion containing host grains having {100} crystal faces that are sensitized by the deposition of protrusions at the intersections of the {100} crystal faces. Protrusion growth is achieved by undertaking final silver introduction in the presence of a benzothiazolium site director containing a 5-position electron withdrawing ring substituent adsorbed to the {100} crystal faces of the grains being grown.
Abstract:
A seed-specific expression vector and its construction methods and applications are disclosed. A fusion protein expression cassette consisting of Arachis hypogaea oleosin gene-apolipopoprotein A-IMilano (A-IM) gene driven by Brassica napus oleosin gene promoter is inserted between the HindIII and SacI sites of a plant binary expression vector pBI121, obtaining the plant expression vector pBINOA of the invention. In addition, a method for producing apolipoprotein A-IMilano is provided, in which the expression vector is used to transform oil sunflower which is used as a plant bioreactor. The method can not only improve the yield of apolipoprotein A-IMilano, but also greatly reduce production costs, and is suitable for industrial production.
