摘要:
The invention relates to enamine resins which are the reaction products of a) an acetoacetylated resin, and a C1-C20 alkyl amine or a mixture of C1-C20 alkyl amines. The acetoacetylated resin is the reaction product of a polyol having 4 or more hydroxyl groups; and at least one acetoacetate. The invention also relates to an acetoacetylated resin which is the reaction product of a polyol having 4 or more hydroxyl groups and at least one acetoacetate, where a portion of the hydroxyl groups of the polyol are replaced by acetoacetate groups and the remaining hydroxyl groups are replaced by a saturated monofunctional carboxylic acid ester, unsaturated monofunctional carboxylic acid ester, or a mixture thereof; as well as to enamine resins prepared from these acetoacetylated resins. The invention also relates to curable coating compositions containing such resins or a mixture of those resins, at least one metallic drier compound; and optionally one or more solvents.

This invention relates to a highly efficient artificial low-density lipoprotein (LDL) carrier system for the targeted delivery therapeutic agents across the blood-brain barrier (BBB). In particular, this invention relates to artificial LDL particles comprised of three lipid elements: phosphatidyl choline, fatty-acyl-cholesterol esters, and at least one apolipoprotein. The present invention further relates to compositions, methods and kits comprising artificial LDL particles for targeting drugs to and across the BBB for the prevention and treatment of brain diseases.
摘要:
A mechanism for forming thin metallic skin enclosures from blanks. The apparatus includes a forming assembly including a plurality of die stations. The stations are stepped farther away from an axis along which blanks being processed are positioned at a plurality of die stations. Grippers spaced from each other along the axis and away from the axis at distances substantially the same as die stations are carried by the transfer assembly. A pneumatic actuator can be used to move the transfer assembly reciprocally in directions generally parallel to the axis between first and second axial positions. In the first position the grippers are registered with corresponding die stations. In a second position the grippers are registered with die stations adjacent the ones with which they are registered when the transfer assembly is in its first position. A ram is provided to move the transfer assembly between first and second stepped positions relative to the axis.

A method for manufacturing a connector for assembling and sealing laminate flooring panels which are separate from the connector, the method comprising: extruding a connector having a base and an extension attached to the base, wherein the extension has a mating member for mating with a flooring panel; and attaching a seal to the connector.
摘要:
A polymeric adhesive tape including a first polymeric adhesive layer which is a heat activated film and a second polymeric adhesive layer which is a heat activated film is disclosed. The tape is designed for use in the fabrication of articles wherein the polymeric adhesive tape secures a first member to a support surface. A method for bonding adjacent sheets to a substrate is also disclosed. In accordance with the disclosed method, a substrate is prepared for application of a first sheet and a second sheet, a polymeric adhesive tape is positioned on the substrate at a position along which the seam between the first sheet and the second sheet will be located, the first sheet and the second sheet are laid on the substrate such that the seam between the first sheet and the second sheet lies along the polymeric adhesive tape, and the adhesive tape is heated along the seam to bond the substrate, adhesive tape, first laminate and second laminate.

A watertight, durable, and attractive edge construction for furniture is provided that is especially designed for ease of installation while maintaining the aesthetic appeal of the furniture edge. The edge construction hereof provides for the snapable insertion of a side molding into the exposed sidewall of a furniture panel, and, through the provisions of designed-in recesses, allows for the expansion of the furniture and side molding material and for the dispersion of the bonding medium used to bond the panel and molding together. The invention is particularly adaptable for use in the construction of countertops or other furniture made from sheets of synthetic resin laminate bonded to support decking.
摘要:
A reforming process is disclosed which comprises contacting a sulfur-containing hydrocarbon material in at least one liquid phase scavenging or sulfur removal zone with at least one manganese-containing composition at conditions to remove at least a portion of said sulfur from said hydrocarbon material to produce a hydrocarbon feedstock having a reduced concentration of sulfur; and contacting said hydrocarbon feedstock with a catalyst comprising a minor catalytically effective amount of at least one platinum-group metal component, optionally, a major amount of a porous solid support, optionally, a minor catalytically effective amount of at least one halogen component, and optionally, at least one rhenium component in the presence of hydrogen at hydrocarbon reforming conditions to obtain a hydrocarbon reformate product.
