Filed: 1985-02-22
Granted: 1991-03-04
Abstract: The present invention resides in the discovery of a new test means for detecting the presence of an ion in an aqueous test sample and determining its concentration. The test means comprises a porous carrier matrix substantially uniformly incorporated with a) a homogeneous hydrophobic mixture containing three principal ingredients: an ionophore capable of forming a complex with the ion, a hydrophobic vehicle, and a reporter substance capable of interacting with the complex of ionophore and ion to produce a detectable response; and b) a buffering substance capable of providing a pH in the range of from about 5 to 10. A test device comprises the test means affixed to one upper flat face of an elongated support member. In use, the aqueous test sample is contacted with the test means or device. The presence and/or concentration of the ion in the test sample is then determined by observing any detectable response produced. The test means and device of the present invention provide rapid results, sufficient detectable response forming in most instances in at least a few minutes.

Title: Inverse shape replication method of making ceramic composite articles and articles obtained thereby
Inventor: NEWKIRK MARC S
IPC: C04B35/622
Filed: 1987-01-27
Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE A method of producing a self-supporting ceramic com-posite body having therein at least one cavity which in-versely replicates the geometry of a positive mold of parent metal, includes embedding the mold of parent metal within a conformable bed of filler to provide therein a cavity shaped and filled by the mold.  The assembly is heated to melt the parent metal mold, e.g., an aluminum parent metal mold, and contacted with an oxidant to oxidize the molten parent metal to form a polycrystalline material which grows through the surrounding of filler, the molten metal being drawn through the growing polycrystalline material to be oxidized at the interface between the oxidant and previously formed oxida-tion reaction product whereby the cavity formerly filled by the mold of parent metal is eventually evacuated by the met-al.  There remains behind a cavity whose shape inversely re-plicates the original shape of the mold.  m e method pro-vides ceramic composite articles having therein at least one cavity inversely replicating the shape of the mold which supplied the parent metal for oxidation.

Title: Implant for the replacement of a tooth or a part of the bone tissue
Inventor: YLI-URPO ANTTI
IPC: A61F2/30
Filed: 1988-06-14
Granted: 1993-11-02
Abstract: ABSTRACT      The invention relates to bone implants e.g. to replace teeth or parts of bone tissue.  It contains metal parts (1) when strength is needed, which are shielded by a bioglass (e.g. Ca-P-glass) mixture attached to the metal.  The glass can be made non-resorbable by metal-oxide additives.  In addition the implant contains a Ca-P-glass mixture which is resorbable to bone or biomass.  Hydroxyl-apatite (HA) can be added both to the resorbable (4) and non-resorbable (2) Ca-P-glass, so that (2) & (4) bind to tissue, to each other and to metal (1).  Binding to bone can be enhanced by addition of an inter-layer between the two layers further from (4) and closer to (2) the metal, which inter layer is made of a mix-ture of slowly resorbable Ca-P-glass and HA.  When high strength is not needed, the metal core is replaced by non-resorbable Ca-P-glass.  The mixture of Ca-P-glass and HA is used also as a granule filler in bonecavities in the invention.
