Abstract: A folding table leg mechanism for mounting to a tabletop, having a leg support with an extension portion and a base portion fixedly mounted to the extension portion, and a mounting mechanism for pivotally connecting the leg support to the tabletop. The mounting mechanism has a hinge joint for pivoting the leg support in a pivot plane substantially perpendicular to the tabletop plane from a collapsed position in which the leg support is substantially parallel to the tabletop to an erect position in which the leg support is substantially perpendicular to the tabletop, and also has a rotation joint for rotating the leg support about a rotation axis substantially perpendicular to the tabletop when the leg support is in the erect position, from a first rotational position to a second rotational position. The leg support may be locked in place when it is in the second rotational position.

Abstract: A semiconductor integrated circuit chip package includes top and bottom interposers 2 and 4, a semiconductor die 14 attached to the top interposer 2, a wirebond 18 or a flipchip connector 52 connected between the die 14 and the top interposer 2, and a tab bond 22 providing an electrical connection from the wirebond 18 or the flipchip connector 52 to outside the bottom interposer 4. A method of making the chip package includes providing top and bottom interposers 2 and 4, attaching a semiconductor die 14 to the top interposer 2, providing a wirebond 18 or a flipchip connector 52 between the die 14 and the top interposer 2, providing a tab bond 22 between the top and bottom interposers 2 and 4, and providing an encapsulant 16 to fill the intermediate volume 40 between the top and bottom interposers 2 and 4.

Abstract: The present invention provides for liposomes formed with alkylammonium fatty acid salts, and methods for manufacturing same. The liposomes of the invention may deliver entrapped load material or materials at the occurrence of a preset triggering condition. Preferred liposomes of the invention are cationic liposomes. The preferred liposomes of the invention are formed with alkylammonium fatty acid salts, e.g., trialkylammonium fatty acid salts of long chain amides. The liposomes of the invention are used to encapsulate both hydrophobic and hydrophilic load materials. The liposomes formed accordingly are capable of delivering their loads upon the occurrence of a trigger or control condition.

Abstract: The running board of the present invention provide the structural integrity to withstand the static and dynamic loads to which articles of this type are normally subjected. The design of the running board in terms of its configuration, the components making up the running board, namely, the blow molded exterior shell and the foam core, have specific structural characteristics. For example, the foam core has a density in the range of 100 kg/m.sup.3 to 150 kg/m.sup.3 and has sufficient resiliency to permit the part to return to substantially its original shape following removal of a load of predetermined magnitude.

Abstract: A salicylic acid (SA) and derivitized beta cyclodextrin complex provides that the SA display increased solubility in water. The complex includes about 0.1 to about 10.0 percent salicylic acid, about 0.1 to about 75.0 percent derivatized beta cyclodextrin and about 0.1 to about 50.0 percent water.

Abstract: A composition containing a protease and glycosidase is provided for removing nits in the treatment of lice infestation. The protease and glycosidase are separated from each other to prevent the protease from hydrolyzing the glycosidase Separation is accomplished by encapsulating either the protease or glycosidase in a lipidic bilayer vesicle while leaving the other outside the vesicle. The protease and glycosidase destroy complex carbohydrate and protein in nit shells, nit embryos and substances secreted by adult lice. In a method of treatment, an infestation site such as hair is treated with a pediculoside and then with the composition containing a protease and glycosidase, and nits are removed such as by washing.

Abstract: A liposome for use in encapsulating both hydrophobic and hydrophilic substances (i.e., a "payload"),is disclosed which is capable of delivering their load upon the occurrence of a trigger or control condition. The liposomes are formed to stably encapsulate a particular active agent to form a delivery vehicle for the agent. The liposomes of the delivery vehicle are stable in a particular environment but become unstable or permeable if passed from the stable environment (e.g., characteristic of a particular pH and/or temperature and/or ionic strength) to a changed or unstable environment, thereby delivering their payload.

Abstract: A cosmetic composition and salicylic acid delivery system includes membrane lipid bylayers formed as liposomes and un-neutralized salicylic acid localized within the lipidic bylayers of the liposomes. Other cosmetic ingredients may be located either within the membrane compartment or in either the external or internal aqueous compartments relative the liposomal bylayers. The composition also includes an organic, water-soluble membrane-impermeant base and water.

Abstract: A cosmetic composition includes (a) ether alcohols conforming to the general formula C.sub.(n) H.sub.(2n+2) O.sub.(n/2), where n is an integer which ranges 4 to 12; (b) a homopolymer of acrylic acid cross-linked with an allyl ether of pentaerythritol or an allyl ether of sucrose, or copolymers of acrylic acid or acrylate derivative/acrylonitrile copolymers, or polyacrylic acid; (c) a fragrance oil or oils, or cosmetically acceptable oils or oily-type materials; and (d) water.

Abstract: Cosmetic and pharmaceutical compositions and methods comprising delivery systems for the controlled release and enhanced penetration of biologically active materials (e.g., Vitamin A) to the skin. The delivery systems comprise cholesteric liquid crystals wherein the active material is retained within the lamellar molecular structure (i.e., between the molecular sheets) of the cholesteric liquid crystal.
