Abstract: A bracket to mount a charge roller and a blade against a photoconductive drum within an image forming apparatus. Bracket may include a pair of guides that extend outward to receive the ends of the charge roller. A biasing device may be positioned to bias the charge roller against the photoconductive drum. The guides may include an opening sized to allow the charge roller to move and maintain contact with the photoconductive drum. A mounting surface may be positioned on the bracket for receiving adhesive to mount the blade. In one embodiment, the bracket is constructed of an electrically conductive material such that a charge introduced to the bracket is delivered to the charge roller.

Abstract: The invention provides a test fluid for detecting coating flaws in a coated web and a method for testing a web coating system. The test fluid includes, water, a polyol, a surfactant, a radiant energy activated tracer compound and an organic solvent selected from the group consisting of an alkylene glycol and a dialkylene glycol. The test fluid is used to identify deficiencies in the web coating system so that adjustments to the web coating system may be made before assembling the coating system in an ink jet printer.

Abstract: An ink jet printer is provided comprising a housing, an ink jet printing apparatus and a coating apparatus. The ink jet printing apparatus is located within the housing and includes an ink jet printing device capable of ejecting ink droplets onto a first side of a printing substrate which moves through the housing along a printing substrate feed path. The coating apparatus is positioned along the printing substrate feed path and spaced from the printing device. The coating apparatus applies a substantially uniform layer of coating material onto at least a portion of the first side of the printing substrate.

Abstract: A method for selecting chemical grade silicon metalloid having improved performance in a direct process for making organohalosilanes. The method comprises (A) heating a chemical grade silicon metalloid sample at a temperature ramp speed controlled to effect a stepwise reduction of oxide impurities present in the chemical grade silicon metalloid to a temperature greater than about 2300.degree. C. in the presence of a carbon source thereby effecting the formation of a reduction product consisting of carbon monoxide and carbon dioxide, (B) determining the amount of the reduction product formed above a temperature of about 1900.degree. C., and (C) selecting a chemical grade silicon metalloid for use in the direct process for making organohalosilanes based upon the amount of the reduction product formed above a temperature of about 1900.degree. C.

Abstract: A flash gas filter system detects a low level of refrigerant flowing in a conduit of a refrigeration system by measuring a temperature drop across a sub-cooler connected to the conduit. The sub-cooler has a liquid process circuit for passing the refrigerant and a refrigerating circuit connected by a manual expansion valve to an outlet of the liquid process circuit for producing a predetermined temperature drop across the sub-cooler when the refrigeration system is fully charged. The temperature drop in the refrigerant is reduced by the presence of bubbles caused by a low refrigerant level. The reduced temperature drop is detected and an alarm signal is generated by a computerized filter system control. The control also can monitor liquid line temperature for protection against malfunctioning condensers generate maintenance information and warn of potential malfunction conditions.
