Abstract: The present invention provides an apparatus and method of body contouring and skin conditioning. The apparatus 10 treats cellulite and the like by producing vibrations in the subcutaneous layers of fat. A cup 18 of handpiece 16 is placed against the skin to create a chamber 60. A vacuum source 160 and compressor 162, which are in communication with chamber 60, are then controlled to produce an oscillating pressure within the chamber 60. This vibration of the skin surface is transferred through the dermal layers thereby influencing fluid retention and cellulite build up.

Abstract: The present invention relates to an assembly having a handle, cap and abrasive disc for use in dermabrasion. The assembly is able to be used to vigorously abrade the skin when said abrasive disc protrudes beyond and through an opening in said cap. The abrasive disc can then be retracted or repositioned within a chamber enclosed by said cap and the tool can be used to draw off the dead skin particles or gently abraded the skin surface. The tool of the present invention has the ability to be adjusted to the specific requirements of the user as the same handle allows the attachment of variously sized abrasive discs and caps to facilitate treatment.

Abstract: The present invention provides an apparatus and method of body contouring and skin conditioning using a mobile handpiece 16. The mobile handpiece 16 treats cellulite and the like by producing vibrations in the subcutaneous layers of fat. A cup 18 of the mobile handpiece 16 is placed against the skin to create a chamber 60. A vacuum source 160 and compressor 162, which are in communication with chamber 60, are then controlled to produce an oscillating pressure within the chamber 60. This vibration of the skin surface is transferred through the dermal layers thereby influencing fluid retention and cellulite build up.

Abstract: The present invention relates to an apparatus and method for delivering or infusing oxygen into the deep layers of the skin. This is achieved through firstly spraying the skin area with a pre-oxygenated fluid and then causing the solution to permeate into the skin by applying a greater than atmospheric pressure to the sprayed skin. The apparatus provides for an air compressor that draws fluid from a tank to be sprayed through a trigger nozzle onto the skin. The end of the nozzle further includes a cavity defined by a peripheral skirt that engages against the skin to seal and pressurise an area.

Abstract: A microabrasion apparatus for providing treatment of skin or other surfaces whereby a pneumatic source [(12, 38)] is operatively connected to a recovery container [(14, 22)] and to a hand tool [(16, 12)] and to one of a plurality of supply containers [(18, 26)] that house treatment particulates. A valve [(30)] controls which supply container [(18, 26)] provides the treatment particles. In operation, the user can select from different supply containers and thus different particles each of which performs different types of treatment such as abrasion. In addition, there is provided the use of a microabrasion apparatus using organic particulates that provide natural treatment of skin.

Abstract: The present invention relates to a hand tool used for dermabrasion, wherein said hand tool includes an abrading surface and a smooth or vacuum surface where the abraded material, typically the skin, can be removed from the surface by suction. This is achieved by providing an abrasive tipped hand-tool including a vacuum aperture wherein the surface surrounding the aperture is of a smooth character enabling the vacuum to be smoothly applied across the skin only when no abrading is taking place.

Abstract: A pressure sensitive adhesive composition includes an alkenyl-terminated polydiorganosiloxane, a silanol-terminated polydiorganosiloxane, a resinous copolymer, an organohydrogenpolysiloxane with terminal Si—H groups, a hydrosilation catalyst, and an organic cross-linking agent. The composition provides excellent high temperature adhesion properties and enables coatable formulations with low solvent content.

Abstract: A process for making bis(ether anhydrides) employs alkylamines having low melting temperatures thus allowing for novel intermediate process steps for preparing bis(ether anhydrides). The alkylamines have alkyl groups which contain at least three carbon atoms and have boiling temperatures in the range of 48 to 250.degree. C. at atmospheric pressure. As a result of using these amines, liquid alkylamines now can be employed in the imidization process step. The N-alkyl nitrophthalimides prepared from the recovered imidization product according to this invention can now be purified using liquid/liquid extraction or vacuum distillation. The alkyl nitrophthalimides prepared according to this invention provide for displacement reactions which now can be run at a high solids level. Likewise, the exchange reaction can be run at a higher solids level, and thus achieves an efficiency level which is higher than conventional processes.

Abstract: A battery separator fabric comprising a nonwoven fibrous web of thermoplastic fibers having top and bottom surface fibers and inner fibers. The surfaces of the top and bottom surface fibers of the fibrous web are seared and fused together to form film-like surfaces having pores, while the surface fibers and inner fibers of the web remain substantially unaffected. Searing and fusing of the surface fibers are accomplished by simultaneously applying heat to the top and bottom surfaces of the fibrous web so as to sear the surfaces of the thermoplastic fibers, and pressure to ensure that the seared fibers make contact with each other to secure themselves together. As the seared fibers make contact with each other, film-like surfaces are formed with pores being created in the surfaces. The pores are created because a majority of spaces remain between the surface fibers.
