Abstract: A method of treating a surface to be contacted by a protein-containing fluid reduces protein adsorption to the surface. The method comprises coating or siliconizing the surface with a lower alkyl silane selected from the group consisting of monoalkyl silanes of the formula RSiX.sub.3 wherein R is selected from ethyl and branched (C.sub.3 -C.sub.5) alkyl and X is selected from hydrolyzable groups, such as halogen or lower alkoxy, and dialkyl silanes of the formula R'.sub.2 SiX.sub.2 wherein R' is (C.sub.2 -C.sub.5) alkyl and X is as described above. For example, borosilicate glass vessels for storing blood may be treated.
Abstract: A donor modified strontium titanate formulated to become conductive when sintered in air, is further modified with a minute quantity of manganese and sintered to maturity in a nitrogen atmosphere. A paste including silver particles, and oxides of bismuth and copper is applied to two major portions of the body. The coated body is heated at about 920.degree. C. to oxidize the grain boundaries and to form silver electrodes tightly adhered to the body.
Abstract: This invention is concerned with a process for applying a protecting silicon-containing coating on a superalloy. The invention further concerns the thus obtained specimens having a protective coating.
Abstract: A process of warp sizing polyester filaments and hydrophilic finishing polyester fabrics which comprises (1) coating said polyester with the water-soluble polyester of a dihydric alcohol having two to six carbon atoms and an aromatic polycarboxylic acid compound having three, four or five carboxy groups and (2) drying said polyester onto said filament or (3) curing said polyester onto said fabric.
