Abstract: Chemically treated glass fibers having good processability are useful in producing fiber reinforced polymeric matrices, wherein the glass fibers have controlled wettability and are not detrimental to the weatherability of the fiber reinforced polymeric matrices.  The chemically treated fibers have the dried residue of an aqueous chemical treating composition having a bisphenol A polyester film forming polymer compatible with and soluble in the matrix polymer, poly(vinyl acetate) polymeric film former, acryloxy-containing or methacryloxy-containing organo coupling agent in an effective coupling agent amount, cationic fiberous lubricant in an effective lubricating amount, with or without a cationic organic quaternary ammonium salt having alkoxy moieties, and with water in an amount to give a total solid for the aqueous chemical treating composition in the range of about 1 to about 30 weight percent.          In addition, the aqueous chemical treating composition can have one or more amino-containing organofunctional silane coupling agents.  The amount of the organic quaternary ammonium agent generally is in the range of from 0.05 to around 0.4 weight percent of the aqueous chemical treating composition.  When this agent is not in the aqueous chemical treating composition, a secondary application of an antistatic agent is performed.  The chemically treated glass fibers can be produced in any form such as chopped strand or continuous strand for combination with polymeric matrices including both filled and unfilled systems for producing reinforced polymeric matrices such as glass fiber reinforced polymeric panels which can be clear, translucent or pigmented.

Abstract: A process for manufacturing combustible gaseous products comprising mainly hydrogen and carbon monoxide from carbonaceous materials includes maintaining a substantially constant volume level of a carbonaceous material above a first electric arc zone in a primary reaction chamber that includes a source of water adjacent the electric arc zone; continuously moving the carbonaceous material downwardly through the primary chamber while activating the electric arc to electrothermally and photochemically activate the gasification of the material and produce a raw product gas therefrom; passing the raw product gas upwardly through the downwardly moving carbonaceous material in countercurrent heat exchanged therewith to initiate pyrolysis of the incoming material and to produce both a condensable and noncondensable product; removing raw product gas and noncondensable product from the top of the primary chamber and introducing it into a secondary chamber in which an incandescent coke bed is maintained; refluxing the condensable product with the downwardly carbonaceous material in the primary chamber while passing the raw product gas and noncondensable product admitted into the secondary chamber through the incandescent coke bed to produce the refined product gas.  An apparatus for effecting this process is also described, and includes a means for maintaining a substantially constant volume level of the carbonaceous material in the primary chamber; and means for maintaining the coke bed in the secondary chamber in an incandescent state through the use of electric arc heaters in circuit with the coke bed in the secondary chamber.  The apparatus furthermore includes a conduit for removing raw product gas from the top of the primary reaction chamber and introducing it into the top of the secondary reaction chamber as well as a conduit for removing refined product gas from the bottom of the secondary chamber.

Abstract: Use of (C1-C5) alkyl esters of aliphatic (C8-C22) mono-carboxylic acids  for  removing  fat,  inks and the  like from  printing  apparatus,  in  particular  from  offset printing machines, and a cleaning agent for this, con-taining as its main component a (C1-C5) alkyl ester of an aliphatic (C8-C22) monocarboxylic acid or a mixture of such esters. The most suitable esters are methyl, ethyl or isopropyl esters or mixtures thereof, and particularly expedient is an ester mixture obtained by interesterification of an oleic acid containing oil or by esterification of an acid mixture having a corresponding composition. The ester or ester mixture may be admixed with up to 50 % by weight of vegetable oil. Further,  the  ester  or  ester  mixture  or  the  mixture thereof with vegetable oil may be emulgated in water in such amount that the water phase comprises up to 50 %, preferably 25-35 % by weight of the emulsion using an emulsifier in an amount of 1-10 %, preferably 3-5 % by weight of the emulsion. In that case it is convenient to further add a corrosion inhibitor in an amount of up to 2 %, preferably 0.5-1 % by weight of the emulsion. These esters and mixtures are low viscosity substances which  are  excellent  and  quickly  acting  solvents  for inks,  etc.  They are moreover biologically degradable, non-toxic and have a low vapour pressure so that they do not involve any risk for the environment.
