Abstract:
A process for printing and transferring an image from a receiver sheet having a thermally transferable film to a final substrate. Only the imaged area of the film is transferred and permanently fixed to a final substrate, while the non-imaged area is processed to have little or no affinity for the final substrate, and is not bound to the final substrate.
Abstract:
A coated media is printed with ink. The area of the media which is not covered with ink is cured by exposure to radiation, and the printed image is transferred to a final substrate. The media is coated with a radiation curable coating. Upon exposure to electron beam or ultraviolet radiation, the coating in the exposed, non-imaged, area cures, and becomes permanently bonded to the base sheet. The ink layer of the imaged area effectively blocks, absorbs and/or reflects the radiation and does not allow polymerization under the imaged area. The image is transferred to a final substrate by placing the image in contact with the final substrate, followed by the application of energy. The image is permanently bonded to the final substrate. No overprint, or non-imaged area, that is visible or which may be felt by touching, is transferred to the final substrate.
Abstract:
This invention describes novel purified and isolated nucleic acid molecules or the fragments thereof, extracted from nematode or arthropod pests or recombinant, which encode P-glycoprotein homologs and regulate resistance to the macrocyclic lactone compounds. The invention further relates to the new P-glycoprotein homolog expression product of these nucleic acids. Also described herein are methods for detecting the gene encoding for resistance to the macrocyclic lactone compounds in nematode or arthropod pests which comprise comparing the nucleic acids extracted from a pest specimen to the nucleic acids encoding for resistance and the nucleic acids encoding for susceptibility to the macrocyclic lactone compounds. Lastly, the present invention is also drawn to methods and compositions for increasing the efficacy of the macrocyclic lactone compounds against resistant nematode or resistant arthropod pests which comprise administering to a mammal or applying to crops and the like a pesticidal enhancing effective amount of a multidrug resistance reversing agent.
Abstract:
A system and method for increasing capacity of a cellular system by reducing call overhead processing and transmission congestion previously required in updating a subscriber's mobile station data position as the subscriber moves among locations within a geographic area served by a network service provider is presented. A predetermined N number of copies of mobile station subscriber data is distributed among multiple Visiting Location Registers (VLRs) within the area served by a cellular system. Unlike previous systems, when mobile stations traverse location boundaries, the current VLR corresponding to the current location does not need to update the subscriber data if that data has not changed since the subscriber was last in that location.
Abstract:
A liquid crystal shutter and a drive waveform for controlling the same is presented by this invention. The liquid crystal shutter includes two distinct layers of liquid crystal material where one layer has a right hand twist sense and the other layer has a left hand twist sense. An electric field is selectively applied to the layers of liquid crystal material which have dual frequency properties. Accordingly, when a low frequency is applied to the liquid crystal materials they exhibit a positive dielectric anisotropy and a homeotropic texture which is substantially transparent. When a high frequency electric field is applied to the liquid crystal materials they exhibit a negative dielectric anisotropy and a planar texture which is substantially reflective. The liquid crystal material may be selected to selectively reflect predetermined spectrums of light. By alternatingly applying low and high frequencies to the liquid crystal shutter, the transition time between the transparent and reflective states is minimized.
Abstract:
An image is printed on a medium by means of a computer driven printer using an ink composition comprising heat activated dye solids, without activating the dye solids during the process of printing onto the medium. The image is transferred from the medium to the object on which the image is to permanently appear by applying sufficient heat and pressure to the medium to activate the dye and transfer the image to the object. The liquid form of the ink composition uses a liquid carrier and an emulsifying enforcing agent which has an affinity for the dye. The emulsifying enforcing agent shields the heat activated dye both prior to, and during, the printing process.
Abstract:
An image is permanently transferred to a substrate having a cotton component, or other component which is absorbent or porous, from a medium printed with the image by a computer driven printer. A polymer surface preparation material is printed by the computer driven printer onto the medium and over the image without printing the material substantially beyond the margins of the image and onto unprinted portions of the medium. The image is transferred from the medium to the substrate by applying sufficient heat and pressure to the medium to transfer the ink and the surface preparation material, with the surface preparation material bonding the ink to the substrate.
Abstract:
An image is permanently transferred to a substrate having a cotton component, or other component which is absorbent or porous, from a medium printed with the image by a thermal printer using heat activated ink. A polymer surface preparation material and the ink are transferred by the thermal printer to the medium from a ribbon containing the ink and the surface preparation material, without activating the ink or the surface preparation material. The image is transferred from the medium to the substrate by applying sufficient heat and pressure to the medium to activate and transfer the ink and the surface preparation material, with the surface preparation material bonding the ink to the substrate.
Abstract:
A re-calcination and extraction process for the detoxification and comprehensive utilization of chromic residues, comprising adding small amount of residue ore powder, sodium carbonate, or additionally, a certain amount of coke powder to the poisonous chromic residues, and calcining the mixture in a re-calcinating apparatus at 1000.degree.-1200.degree. C., for 30-60 minutes. The re-calcined grog is extracted with water, to obtain an extractive liquor containing sodium chromate. The extractive liquor can be used to produce chromium oxide, basic chromium sulfate or medium chrome yellow; while the extracted residues can be sintered at high temperatures with iron ore powder and coke to obtain a massive self-melting sintered iron, which can be further converted to a low-chromium cast iron. This process can thoroughly detoxify the chromic residues, effectively recover Cr2O3 and remove water-soluble Cr+6, whereby various important industrial materials are produced. The method brings very good economical and environmental benefits.
