  • Patent number: 5503939
    Abstract: The invention relates to a process for the production of two-coat finishes, in which a pigmented aqueous basecoat is applied, the basecoat obtained is coated over with a clearcoat, and basecoat and clearcoat are baked together. The process according to the invention is distinguished in that the aqueous basecoat contains an emulsion polymer which has been prepared in the presence of a reaction product (A), the reaction product (A) being obtained by reacting(i) a butadiene homo- or copolymer,(ii) at least one fatty acid of a drying oil or at least one drying oil or a mixture of at least one fatty acid of a drying oil and at least one drying oil, and(iii) maleic anhydridein a mass ratio of (i):(ii):(iii)=1.0:0.1 to 0.6:0.1 to 0.6 and, after adding a basic aqueous solution, converting the reaction product to an aqueous dispersion.

  • Patent number: 5407703
    Abstract: In the manufacture of a ceramic membrane for micro-filtration having a porous ceramic carrier and a ceramic micro-filtration coating on a bulk surface of said carrier, the steps are performed of(i) silanizing said carrier at least at said bulk surface thereof,(ii) after step (i), applying a coating film containing metal oxide to said bulk surface of said carrier by contacting a stable suspension of non-agglomerated metal oxide particles with said bulk surface and moving said suspension along said bulk surface, so that said coating film remains adhering to said bulk surface, and(iii) drying and heating said carrier and said coating film thereon, so as to sinter at least said coating film and thereby form said micro-filtration coating on said carrier.In order to improve the uniformity and evenness of the coating film of the suspension, the stable suspension contains an organic additive which increases the yield stress of the stable suspension to a value greater than zero.

  • Patent number: 5370899
    Abstract: An elongated catheter having an interior and an exterior surface, wherein the interior surface defines a lumen passing through the catheter. The catheter further including an enclosed cavity between the interior and exterior surfaces which encircles of the lumen. The cavity having an inner wall and an outer wall, the outer wall being a resilient sleeve which can stretch generally independently of the inner wall. The cavity containing an amount of a suitable lubricating substance effective to permit the resilient sleeve to slide along an outer surface of the inner wall while in lubricated contact therewith when stretched independently of the inner wall, wherein the inner wall and the outer wall are joined together at distal end proximal ends of the enclosed cavity. An automated method for producing the same, including a series of automated dipping steps, is also disclosed.

  • Patent number: 5360628
    Abstract: The present invention is addressed to providing a simple, yet reliable method for labeling an object for its verification. Broadly, the method of the present invention for labeling an object for its verification commences with applying to a predetermined location on said object, a mark which creates a permanent impression thereof which is perceptible to the unaided or naked eye and a mark which creates a permanent impression thereof which is imperceptible to the unaided or naked eye, yet which can be determined by mechanical, electrical, and/or biologic means. In prior U.S. Pat. No. 5,194,289 a combination of UV eye and amino acid/protein fragment was used to label objects for their identification. The present invention broadens such dual labeled scheme to include a variety of additional "invisible" labeling techniques. Additionally, the present invention includes the recognition that, in order to stop counterfeiting of records and like consumer goods, a visible mark also must be present on the object.
