摘要： Carbon fiber mat are embedded in a coating by first rolling on a coating of e.g. epoxy on the floor or wall, then applying sheets of fine carbon fibers, (optionally) removing the carbon fiber which is not adherent after the coating has dried, then applying one or more additional top coats of coating to additionally embed the carbon fibers. The result is an electrically conductive floor and/or wall coating system useful in antistatic rooms such as clean rooms, operating rooms, etc. Coatings can be sol vent based or waterborne urethanes, epoxies, alkyds, polyethylenes, acrylics, vinyls, vinyl acetates, esters, polyesters, sulfones, polysulfones, silicones, polysilicones and others. The preferred mats are carbon fiber "veils" or "paper" generally having a density of about 0.75 oz./square yard.

摘要： Broadly, the present invention is directed to a pressure sensitive adhesive that possesses enhanced adhesion to low surface energy substrates. The inventive PSA comprises the free-radical polymerization reaction product prepared in the presence of a free-radical initiator and dispersed in organic solvent of between about 0.5% and 10%, by weight of the non-volatile solids of the reaction product, of an organic solvent soluble, high ethylene-containing polymer; and a mixture of ethylenically-unsaturated monomers. Such mixture of monomers comprises between 0% and not substantially above about 10%, by weight of the non-volatile solids of the reaction product, of an ethylenically-unsaturated carboxylic acid or anhydride; and the balance being a non-carboxyl/non-anhydride-functional vinyl monomer or mixture of monomers. The T.sub.g of the polymerized mixture of monomers is not substantially above about -20.degree. C. The polymerization reaction product has a molecular weight which ranges from between about 100,000 and 600,000 and a T.sub.g not substantially above about -20.degree. C. Optionally, the reaction product can be cross-linked with an aluminum, titanium, or zirconium salt or chelate. Also, the reaction product can be cross-linked with a melamine resin. A preferred reaction product comprises ethylene vinyl acetate copolymer grafted with a mixture of monomers comprising acrylic acid, methyl methacrylate, isobornyl methacrylate, and 2-ethylhexyl acrylate. The reaction product additionally may contain unreacted components including the high ethylene-containing polymer, and one or more of the mixture of ethylenically-unsaturated monomers.

摘要： The present invention is based on the unexpected discovery that the low profile additives (LPA) disclosed in U.S. Pat. No. 5,116,917 provide effective shrinkage control when used with various blends of vinyl ester and polyester resin systems. This LPA is unique in that its low profile efficiency is not affected by the different reactivities displayed by blends of vinyl ester resin and polyester resin at different blend ratios. This LPA is equally effective in formulations of all vinyl ester resin, all polyester resin, or any combination of such two resins. The present invention, then, is directed to a thermosettable resinous composition of between about 0 and 95 wt-% of a thermosettable vinyl ester resin; between about 5 and 100 wt-% of a thermosettable polyester resin; and between about 5 and 40 wt-% of a low profile additive comprising a non-gelling, saturated polyester formed from dibasic acid and an EO/PO block copolymer having an EO/PO molar ratio ranging from about 0.1 to 0.9, said polyester having an acid value of greater than about 10. The EO/PO polyether polyol can be built on a combination of diol, triol or other compound with active hydrogen groups, so long as the LPA product does not gel.
摘要翻译：本发明基于意想不到的发现，即在美国专利No. 当与乙烯基酯和聚酯树脂体系的各种共混物一起使用时，提供了有效的收缩率控制。该LPA是独特的，因为其低轮廓效率不受不同共混比下乙烯基酯树脂和聚酯树脂的共混物显示的不同反应性的影响。该LPA在所有乙烯基酯树脂，所有聚酯树脂或这两种树脂的任何组合的配方中同样有效。然后，本发明涉及可热固的乙烯基酯树脂的约0至95重量％的热固性树脂组合物; 约5-100重量％的热固性聚酯树脂; 和约5至40重量％的低分子添加剂，其包含由二元酸形成的非胶凝的饱和聚酯和EO / PO摩尔比为约0.1至0.9的EO / PO嵌段共聚物，所述聚酯具有大于约10的酸值。只要LPA产物不凝胶，可以将EO / PO聚醚多元醇构建在二醇，三醇或其它化合物与活性氢基团的组合上。

摘要： The conventional wye (where the clean regenerated catalyst returns from the regenerator to contact the feed as it enters the riser) is replaced with two or more wyes, all connected between the regenerator outlet and the inlet to a common short cracking riser. Each wye has a separate injector which can inject; e.g., diesel oil, so that neat (unmixed) diesel contacts clean catalyst and the mixture rises up a smaller riser before entering a short main riser where the largely cracked mixture is admixed with similar cat-vacuum bottoms, etc. mixtures from the other wyes. Most cracking occurs before entering the common riser so the effect is similar to a riser cracker operating on a single unmixed feed.
摘要翻译：传统的叶片（其中清洁的再生催化剂从再生器返回到进料器进入提升管时与进料接触）用两个或更多个叶片代替，所有两个或多个叶片全部连接在再生器出口和入口之间以连接到共同的短裂纹提升管。每个眼睛都有一个可注射的单独注射器; 例如柴油，使得整齐的（未混合的）柴油接触清洁的催化剂，并且混合物在进入短的主提升管之前升高较小的提升管，其中将大部分裂化的混合物与类似的真空底部等混合，。大多数裂纹发生在进入普通提升管之前，因此效果类似于在单个未混合进料上操作的提升裂解器。

摘要： Improved catalytic process for carrying out heavy hydrocarbon conversion in the presence of metal on the catalyst and in the feedstock, by catalytic cracking such heavy carbometallic oils to lighter molecular weight fractions. The discovery of a ferro/superparamagnetic component of older catalyst, which when present, can be employed to achieve enhanced magnetic separation of aged catalyst. This invention utilizes this property to enhance separation of more magnetically active, older, less catalytically active and selective, higher metals-containing catalyst particulates from less magnetically active, lower metal containing particulates. The more catalytically active and selective catalysts fractions, are then recycled back to the process.
