Abstract: The invention is directed to methods and compositions for reducing the deposition of pitches and stickies in a papermaking process. The method involves introducing an anionic glycerol-based polymer to the papermaking process. This anionic polymer prevents the pitches and stickies from depositing and agglomerating in papermaking processes.

Abstract: A method for improving yield of petroleum hydrocarbon distillate in a distillation tower (6) comprises: preheating raw oil of petroleum hydrocarbon ready for fractionation; feeding it to a vaporization section (11) through a pressure feed system (3) under a pressure 100-1000 kPa higher than the vaporization section (11) of the distillation tower (6) for simultaneous atomizing and vaporizing; then feeding it to a fractionation section (13) for distillation-separation; and finally, discharging distillate product from the top and/or side of the tower and unvaporized heavy oil from the bottom. A distillation tower (6) for improving yield of petroleum hydrocarbon distillate comprises a vaporization section (11) and a fractionation section (13), and further comprises a pressure feed system (3) for feeding the raw oil of petroleum hydrocarbon ready for fractionation under a pressure 100-1000 kPa higher than that in the vaporization section (11) of the distillation tower (6).

Abstract: A hash algorithm-based data storage method and apparatus are disclosed, including: pre-configuring L number of backend storage modules and a mapping relationship between identifiers of the backend storage modules and a modulo L operation; calculating a key value of data to be stored using a hash algorithm; performing a modulo L operation on the obtained key value and, using the mapping relationship between identifiers of the backend storage modules and the modulo L operation, outputting the key value in the modulo L operation and the corresponding data to a backend storage module with a corresponding backend storage module identifier; determining a preconfigured hash table in the backend storage module does not contain data to be stored, and storing the data to be stored and the corresponding key value. By using the present invention, requirements on storage devices can be lowered and the storage efficiency can be improved.

Abstract: The present disclosure teaches a method and apparatus to gel a dopant material, which may be a low viscosity liquid, and apply it towards beneficially coating dopant liquid in the manufacture of a three-dimensional thin-film solar cell substrate. As an alternate to using high viscosity dopants, a dopant coating liquid, which is typically distributed in low viscosity alcohol based liquid forms, may instead be utilized as a dopant material in a gelatinous state towards the manufacture of a three-dimensional thin-film solar cell substrate. The methods and devices disclosed herein provide for enhancing the high viscosity characteristics of a dopant material. The present disclosure teaches the use of the dopant material in its gelatinous state towards an exemplary cavity filling method.

Abstract: A method and apparatus for transferring material on at least a portion of an uneven surface of a substrate in the manufacture of photovoltaic cells, which may include, but is not limited to a thin-film solar substrates (3-D TFSS). An apparatus for transfer coating onto an uneven surface comprising an applicator roll, a transport roll, a heating device, a drying system, a conveying system, a reservoir, a blade, and a substrate. A method for positioning a substrate, selectively coating the material on an uneven surface, compressing the material to conform at the uneven surface, heating the material to a temperature more than that of the substrate, and drying the material to form continuous material coverage on said uneven surface. A method and apparatus for passing the substrate in a controlled environment, agitating the material prior to step of selectively coating, and heating the conveying plane.

Abstract: A system for preventing printing of duplicate barcodes includes a server (1), a database (2), a number of user computers (3), and a printer (4). The server includes: a print parameter initializing module (22) for initializing print parameters; an initial barcode number determining module (23) for searching for a highest barcode number that has been previously printed according to a preset print date and a part number, and for adding one to the highest barcode number in order to create an initial barcode number for the first printed barcode; and a barcode print controlling module (24) for managing operations of printing barcodes in order to prevent the printer from printing duplicate barcodes. The barcode print controlling module comprises a print controlling sub-module (241), a print determining sub-module (242), a print quantity checking sub-module (243), and an impaired barcode printing sub-module (244). A related method is also disclosed.
