Abstract: Disclosed is a novel system for suspending artwork, photographs, documents and other planar material for display in which one edge (the top edge of the material) instead of being attached to hinges, is positioned between opposed magnetic materials having a strong reciprocal force tightly gripping the planar material therebetween whereby the planar article is releasably mounted for display. One of each set of opposed magnetic materials is seated within a recessed area of a mounting board providing a backing for the artwork or other planar article; while the other magnetic material is seated within a mat or other planar material designed to be positioned over the face of the artwork or other planar material to be displayed. It is particularly useful for mounting for display priceless artwork and archival documents which can suffer irreversible degradation from the hinging techniques heretofore employed for such priceless planar materials.

Abstract: Disclosed is a zinc-oxide containing sol comprising a core of cerium dioxide sol the surface of which particles is coated with zinc oxide; and the method of making the sol. The sol has a mean particle size of less than 50 nm, is characterized as being clear and transparent and is stabilized to resist agglomeration and particle size increase. An essential part of the disclosed invention is the addition of a positive charged oxide such as yttrium oxide to effect the stabilization before significant changes in transparency, agglomeration and/or particle size increase can occur.

Abstract: A polarized manifold connection device for connecting multiple conduits from a compression sleeve having inflatable chambers to multiple tubing from a source of pressurized fluid is disclosed. The connection device comprises a male connector half and a female connector half each having a similar visually perceptible asymmetrical configuration of their respective housings defined by rigid elements which resist deformation of the housings. Thus, the two halves can be connected in only a single orientation. In this manner, the conduits from the source of fluid are uniquely connected to the conduits from the inflatable chambers. The connection device incorporates a releasable locking mechanism which allows the connector halves to be connected by pushing them together and disconnected by pulling them apart without excessive force.

Abstract: The invention features a fluid drainage element which includes a housing having integral front and side walls and a back wall adapted to fit in fluid communication with a urine collection bag, the walls defining a chamber in the housing. The housing also contains a tubular section integral with the front wall, the tubular section including an inner wall defining a lumen which is in fluid communication with the chamber. The inner wall includes one or more ribs arranged circumferentially and shaped so as to maximize the cross-sectional area of the inner wall, act as an integral tubing stop, and additionally to promote capillary flow of fluid through the tubular section and into the chamber.

The needle is slidable through the housing and the viscous material contained therein. The viscous material is fluid enough for the needle to slide therethrough, yet semi-solid enough to conform to the housing distal inner seat so as to form a seal thereat and prevent flow of fluid or air through the lumen.

Abstract: Disclosed are improved metal foil tapes meeting Underwriter Laboratories (UL) requirements and specifications for use with rigid fiberglass air ducts, the tapes having a pressure-sensitive adhesive layer consisting essentially of the crosslinked copolymer of operative amounts of: (1) ethylenically unsaturated carboxylic acid containing 3-6 carbon atoms within the range of 2-15 parts by weight of total polymer; and (2) acrylic and/or methacrylic acid ester of a non-tertiary alcohol having 1-14 carbon atoms within the range of 85-98 parts by weight of total polymer.

Abstract: The invention features a needle and a housing having a proximal inner surface and a distal inner seat leading to and defining a lumen, wherein the needle is slidable through the housing to occupy the lumen. The housing contains and is cooperable with a valve shaped so as to sealably fit against the housing distal inner seat, the valve including a hole alignable with the lumen. When the needle slidably occupies the housing, the valve hole, and the lumen, the valve is prevented from sealably fitting against the housing distal inner seat. The housing also contains an outward biasing means biased against the valve. Upon removal of the needle from the housing, the outward biasing means urges the valve sealably against the housing distal inner seat so as to prevent flow of fluid or air through the lumen.
