Title: Preparation and use of mullite whisker networks
Inventor: DOTY PETER A
IPC: B01D39/20
Filed: 1991-12-13
Abstract: A process for producing mullite whiskers includes heating a non-stoichiometric mixture containing aluminum and silicon to a temperature within a range of 500 ·C to 950 ·C in the presence of SiF4 gas to form fluorotopaz and then to a temperature within a range of 800 ·C to 1500 ·C to convert the fluorotopaz into mullite. A  mullite whisker-forming composition that procudes an interlaced network of single crystal mullite whiskers with a controlled permeability comprises a mixture of an aluminum-containing material with a silicon-containing material and a fluxing agent which melts at temperatures below 1000 ·C. The ratio of aluminum atoms to silicon atoms in the resultant product is approximately non-stoichiometric. The network may, for example, be used to fabricate a regenerable exhaust gas filter element for diesel engines.

IPC: G03B27/46
Filed: 1993-06-24
Abstract: A Process for Operating a Photographic Processing Apparatus and an Apparatus for Photographic Processing Abstract A photographic processing apparatus which allows the throughput time of a client order to be optimized. The processing apparatus includes a modular design and comprises various processing modules to process exposed photographic film material and/or photographic copy material. The individual processing modules each include one or several processing stations, through which the exposed film material and/or photographic copy material passes in succession, according to demand. The inventive operating process for the photographic processing apparatus is characterized in particular in that the control of the throughput speed and processing speed of the film material and/or the copy material is hierarchically designed and comprises two levels. Here the processing speed of the film material or copy material in any preceding processing station is locally controlled in the given module in accordance with the speed of a processing station through which film material or copy material passes at a constant and predetermined rate. At the same time, the various processing modules are connected by way of signal lines to a superordinate central control unit, which assumes the central control functions and which monitors the operation of the individual processing modules to optimize the throughput of film material and/or copy material through the photographic processing apparatus.
Patent CA-2100886-A1 (CA)
Inventor: KLASSEN R VICTOR
IPC: B41J2/525
Filed: 1993-07-20
Abstract: A method for processing images for printing includes the steps of for each separation, making a pixel level determination of marking material coverage, based on the number of pixels within a given area that are turned on; if a determination is made that too much marking material will be placed within the given area, turning off a fraction of pixels in the area to reduce the amount of marking material that will be used for the given area; and to preventing artifacts from occurring in the pixel reduction step by utilizing a processing order through each given area which tends to randomize the turn off effect. Additionally, the results of the determination are compared for each separation, to determine that the turnoff result allows at least one corresponding pixel among each of the separations to be turned ON.

Title: Method of dispersing solid additives in polymeric resins
Inventor: PAN WIE-HIN
IPC: C08J3/215
Filed: 1993-10-14
Abstract: METHOD OF DISPERSING SOLID ADDITIVES         IN POLYMERIC RESINS            ABSTRACT OF THE DISCLOSURE    A method for dispersing solid forms of additives in polymeric resins involves adding dispersions or solutions of additive(s) to a solution of resin in a tubular mixer (preferably in the presence of a stationary mixer).  The mixer leads to a steam precipitation step wherein all fluid ingredients in the mixture are volatilized leaving the solid additive and resin in the desired ratio.   This results in a uniform dispersion of the additives in the polymer matrix.  As a result of the high dispersion, physical properties of the polymer are preserved.  In one illustration, PTFE as a drip inhibitor additive, is added to polycarbonate resin to obtain a highly dispersed PTFE concentrate of improved drip-inhibition without loss of mechanical properties.
