  • Patent number: 6742295
    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.

  • Patent number: 6187824
    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.

  • Patent number: 5478119
    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.
