Granted: 1994-11-24
Abstract: Xanthine derivatives having general structure (I) including the (R) and (S) enantiomers and racemic mixtures thereof, and the pharmaceutically acceptable salts thereof, wherein R1 and R2 are each independently (C1-C4)lower alkyl or (C2-C4)lower alkenyl Z is (II) or (III) or (IV) wherein R3 is hydrogen, (C1-C3)lower alkyl, nitro, amino. hydroxy, fluoro, bromo or chloro, R4 is (C1-C4)lower alkyl and n is 1 or 2 which act selectively at adenosine receptors and which are in general as adenosine antagonists are disclosed. From in vitro studies it is known that specific physiological effects can be distinguished as a result of this selectivity and that adenosine receptor activity in vitro correlates with adenosine receptor activity in vivo. Pharmaceutical preparations of the subject compounds can be prepared on the basis of the selective binding activity of the compounds disclosed herein which will enhance certain physiological effects while minimizing others, such as decreasing blood pressure without decreasing heart rate.

Title: Methode et appareil de detection du detachement d'un dispositif embolique endovasculaire
Inventor: SCHELDRUP RONALD W
IPC: A61B17/00
Filed: 1995-03-02
Granted: 2000-01-25
Abstract: L'invention concerne un procédé et un appareil permettant d'effectuer une occlusion endovasculaire par la formation de thrombus dans les artères, les veines, les anévrismes, les malformations vasculaires et les fistules artério-veineuses. L'invention se rapporte plus particulièrement à un procédé et un appareil permettant de prévoir le moment où a lieu la séparation électrolytique d'un dispositif (104) de formation d'embolie qui est introduit dans le site de formation de thrombus requis et qui est destiné à y demeurer. Selon la présente invention, un courant continu à courant alternatif superposé (170) est appliqué à la liaison consommable (106) qui couple un élément d'acheminement (tel qu'un fil de guidage) et un dispositif d'occlusion. L'impédance (telle que mesurée par l'amplitude du courant alternatif superposé) est surveillée. Lorsqu'une variation prédéterminée de cette impédance (ou amplitude) a lieu, indiquant ainsi la séparation de l'enroulement, le courant continu est interrompu afin de réduire au minimum ou d'éviter toute électrolyse supplémentaire.

Abstract: A square saw tooth having four cutting edges of the type which is rotatable about its axis on a saw disc to present a fresh cutting edge when the radially outermost edge wears out has carbide wear plates covering the high wear areas of its attack face and providing its cutting edges.  A wear plate is provided at each corner of the attack face, and each wear plate has a flat rear surface for attachment to the tooth body and a front surface of a complex shape, having plateau surface areas at the corners, where the plates are thicker, and one or more cylindrically curved concave surfaces which recede from the plateau areas toward the interior of the attack face, so that the plate recedes in thickness away from the plateau area.  This construction helps provide more uniform wear over the surfaces and edges of the attack face for a more efficient consumption of the wear plates.

Granted: 2001-10-16
Abstract: In a pitless well adapter, an adapter insert from which a flow pipe and pump depends, is normally vertically, slidably and removably held by wedge ribs in an adapter housing.  The top surfaces of the adapter insert and adapter housing are similarly formed such that sliding the adapter insert out of engagement with the adapter housing will enable the adapter insert to be deflected into the casing in a manner which will spare damage to the adapter insert.  The bottom surface of the adapter insert and the adapter housing are of matching contours so as to permit proper seating of the adapter insert in the adapter housing.  The uppermost portion of the wedge ribs are tapered to form a guide surface engageable with the adapter insert upon installation of the adapter insert in the adapter housing.

Title: Alkali metal diffusion barrier layer
Inventor: FINLEY JAMES J
IPC: C03C17/36
Filed: 1997-01-14
Granted: 2000-08-01
Abstract: Amorphous metal oxide barrier layers of titanium oxide, zirconium oxide and zinc/tin oxide are effective as alkali metal ion barrier layers at thicknesses below 180 Angstroms.  The amorphous metal oxide barrier layers are most effective when the density of the layer is equal to or greater than 90% of the crystalline density.  The barrier layers prevent migration of alkali metal ions such as sodium ions from glass substrates into a medium e.g. electrolyte of a photochromic cell, liquid material of a liquid crystal display device contacting the glass surface.  The properties of the medium, particularly electroconductive metal oxide coatings, are susceptible to deterioration by the presence of sodium ions migrating from the glass.  One technique to obtain the desired density of the barrier layers is to provide shields upstream and downstream of the cathode to limit the deposit of sputtered material to sputtered material traveling along a path generally normal to the surface being coated.
