Abstract: A solvent-based thermosetting coating composition comprising a hydroxy functional epoxy-polyester graft copolymer and blocked polyisocyanate crosslinking agent. The coating composition may be formulated as hot sprayable, high solids coating composition suitable for use as chip resistant automotive vehicle primer suitable for use on body panel areas subject to chipping by stones, gravel and other road debris. Alternatively, the composition may be formulated as a high solids composition sprayable with conventional spraying equipment. The hydroxy functional epoxy-polyester graft copolymer is the product of polymerization of lactone monomers in the presence of hydroxy functional epoxy ester resin precursor. The precursor resin is the reaction product of diepoxide chain extended with diphenol and chain terminated with acid component comprising primary hydroxy functional acid. The polymerization of the lactone monomers is carried out at a temperature between about 50.degree. C. and about 300.degree. C.

Abstract: An apparatus and method for locating dropouts. Information as to dropouts in a length of tape is stored in memory and then used to compute data as to location of the dropouts. The data is used to position a tape-inspecting instrument such as a microscope over successive dropouts.

Abstract: A method is disclosed for determining enzymatic activity in a liquid sample by particle agglutination or inhibition of particle agglutination.

Abstract: A security seal having a tag attached to a flat strap at the central portion by a pair of flexible members. The seal is adapted for sealing a box structure or container having a strap in one surface thereof and a hasp attached to the container. The tag extends upwardly so as to be visible against the surface of the hasp and container. Formed in the label and the tag surface, such as by stamping or the like, are a plurality of circular scores randomly positioned. The random positioning may be recorded to provide a means for verification. Any attempt to remove the label from the tag will result in destruction of the label.

Abstract: Azeotropic mixtures of 1,1-difluoro-1,2,2-trichloroethane (HCFC-122) with methanol, ethanol, isopropanol or n-propanol, the azeotropic mixtures being useful in solvent cleaning applications.

Abstract: A unique refrigerant containing three or more halocarbons, each halocarbon after the first having a successively higher boiling point. The refrigerant has a temperature/pressure relation substantially equal to FC-12. Also provided is a method for producing cooling and a method for producing heating using this refrigerant.

Abstract: Large acrylic star polymers containing single- and multi-functional monomers in the core are made by group transfer polymerization techniques, preferably by arm-first, core-first or arm- core- are approaches.

Abstract: Process of polyene hydrocyanation, in particular diene hydrocyanation, wherein a promotionally effective amount of any acid with a pK.sub.a above about 2 and below and 14, preferably aryl alcohols such as phenol and cresols, is used.

Abstract: A connector apparatus comprises a header connector, into which an IC pack is loaded and from which it is unloaded, and an ejector unit detachably mounted on the header connector. The header connector includes a locking lever having a protrusion which is adapted to engage a locking notch in the surface of the IC pack, when the IC pack is loaded. The ejector unit includes a base attached to one surface of the heater connector, a push lever attached to one side portion of the base, so as to be movable in the loading or unloading direction of the IC pack, an unlocking lever formed integrally on the push lever and adapted to engage the locking lever, when the push lever moves in the pack-loading direction, and an eject member movably mounted on the base and having an eject portion adapted to move in the pack-unloading direction as the push lever moves in the pack-loading direction.

Abstract: An improved process is provided for dry spinning spandex filaments which contain titanium dioxide pigment particles and a polymeric tertiary amine stabilizer. An organic base, such as ethylene diamine or diethyl amine, is added to the polymer solution before the titanium dioxide or the polymeric amine stabilizer is added to the solution. Improved spinning continuity and product yield are obtained.

Abstract: Spinnable dopes of poly-p-phenylenebenzobisthiazole, poly-p-phenylenebenzobisoxazole, or poly-2,5-benzoxazole and thermoplastic or intractable polymers in certain mixed solvents are provided.

Abstract: An immunoassay for CK-MB is provided based on the sequential immunoinhibition first by an immobilized and then by a soluble antibody of either the CK-M or the CK-B sub-units in CK-MM, CK-MB aned CK-BB, followed by an enzymatic determination of the unbound sub-unit in CK-MB (the unbound CK-BB or CK-MM having been previously removed).

Abstract: Azeotropic mixtures of 1,1-difluoro-2,2-dichloroethane (HCFC-132a) with methanol or ethanol, the azeotropic mixtures being useful in solvent cleaning applications.

Abstract: Textile treatment compositions are disclosed, comprising polymers of perfluoroalkyl (meth)acrylate and other monomers such as 2-chlorohydroxypropyl methacrylate or other alkyl (meth)acrylates; propylene glycol monomethyl ether; and trichlorotrifluoroethane.

Abstract: A plurality of individual marks are imprinted in the surface of an object to form a plurality of substantially linear, rectangular arrays of preselected width in the surface of the object. Each imprinted substantially linear, rectangular array is spaced a preselected distance from each adjacent imprinted, substantially linear, rectangular array to provide a space of preselected width. The preselected width substantially linear, rectangular arrays and preselected width spaces are combined in alternating fashion to provide a bar code message in the surface of the object.
