Title: Surgical cutting instrument
Inventor: SHULER DONALD K
IPC: A61B17/32
Filed: 1992-02-06
Abstract: ABSTRACT      The cutting strength of a rotary surgical cutting instrument is increased by an on-axis bearing contact between the distal end of its rotatable inner member and the interior surface of its outer member.   The outer member is provided with a distal cutting aperture angularly oriented to the rotation axis and circumscribed by  an  oval  outer  cutting  edge.    The  inner  member  has  two symmetrical  rows  of  straight-sided  triangular  cutting  teeth positioned to cooperate with the outer cutting edge to shear tissue,  including bone,  disposed in the cutting aperture.   A clearance gap between the inner and outer members narrows in width in the region between the teeth and the aperture to prevent severed tissue from lodging between the inner and outer members.   The height of the cutting teeth is at least 50% of their width, and 15% to 22% of the outer diameter of the inner member.  The straight sides of the teeth converge to crests disposed in a first common longitudinal plane.  The teeth are separated by roots disposed in a second plane parallel to the first plane but disposed closer than the first plane to the rotation axis.

Title: Disposable recyclable plastic articles and moldable synthetic resin blends for making the same
Inventor: PETCAVICH ROBERT J
IPC: C08L1/28
Filed: 1992-04-14
Abstract: DISPOSABLE RECYCLABLE PLASTIC ARTICLES AND MOLDABLE SYNTHETIC RESIN BLENDS FOR MAKING THE SAME     ABSTRACT    Environmentally friendly, disposable, degradable and/or recyclable plastic articles, which take the place of environmentally unfriendly styrofoam, are molded from synthetic resin blends comprised of 65% to 95% of water soluble thermoplastic resin having an inverse solubility characteristic and about 35% to 5% of resins and fillers that are functionally compatible with the water soluble resin. The articles are insoluble when they contain a hot beverage or food but become soluble when exposed to tepid or cool water.          The inversely soluble resin may be high molecular weight poly(ethylene oxide) or hydroxypropylcellulose, and mixtures thereof.  By appropriate selection of the compatible resin and the ratio of the compatible resin to the inversely soluble resin, solubility time may be varied from minutes to weeks.  The articles can be dissolved in water or by the moisture in a landfill, or can be recycled by dissolution in cool water, thereby eliminating the trash and garbage problems inherent in the use of nondegradable styrofoam.

Title: Process for the production of optically-active 4-amino-3-hydroxycarboxylic acids
Inventor: BANZIGER MARKUS
IPC: C12P13/00
Filed: 1992-08-21
Abstract: ABSTRACT OF THE DISCLOSURE           A process is disclosed for the production of optically-active 4-amino-3-hydroxy-carboxylic acids in the (rel-3R,4R)  configuration,  especially statine,  starting from  5-alkylidene  or  5-benzylidenetetramic  acid.    The synthesis process includes the 0-acylation of the tetramic acid to form the corresponding 4-acyloxy-3-pyrrolin-2-one, a stereoselective hydrogenation to produce (rel-4R,5R)-4-acyloxy-5-alkyl   or  5-benzylpyrrolidin-2-one   and   an enantioselective  enzymatic  hydrolysis  of  the  (4R,5R)-enantiomer to form the corresponding 4-hydroxypyrrolidin-2-one.    The  nonhydrolyzed  enantiomer  is  separated  and converted   into   the target   compound  with   (3S,4S) configuration by hydrolytic cleavage of the lactam ring and the ester function and optional introduction of an amino protecting group.  Analogously, the (3R,4R)-enantiomer can be obtained from the 4-hydroxypyrrolidin-2-one from the enzymatic  hydrolysis.    The  4-amino-3-hydroxycarboxylic acids produced by the process of the invention are the structural elements of enzyme inhibitors.

Inventor: GOUGEON JAN C
IPC: B63B15/02
Filed: 1992-09-28
Abstract: ABSTRACT A righting system for a multi-hulled sailing vessel with a connecting amidships portion and a floatable mast, universally mounted to a mast step.  Mast support cables, including aft mast support cables, extend from the top portion of the mast to vessel anchor points aft of the mast, and extendable and contractible vessel-anchored tackle systems connect to them.  The righting system includes righting lines extending from each aft mast support cable forwardly to anchors on the hull sides of the vessel substantially forwardly of the connection of the aft stay cable to its vessel anchor points, and a load bearing compression pole which is swivelly connectable to the vessel at the mast and to the one of the aft mast support cables which is out of the water when the vessel is in a side capsized position in which the tip of the mast is floating in the water.  After the pole is affixed, the aft mast support cable in the water is tautened, while holding the aft mast support cable which is out of the water outwardly away from the mast step with the pole.  This causes the lower end of the vessel to pivot with respect to the mast while the righting line attached to the out-of-the-water aft mast support cable assumes a portion of the load from the aft support cable to which it attaches.   When the hulls reach upright position, the formerly out-of-the-water tackle system is tautened to fully right the mast with respect to the hulls, while the pole continues to hold the aft mast support cable outwardly away from the mast.

Title: Engine brake timing control mechanism
Inventor: CUSTER DENNIS R
IPC: F01L13/06
Filed: 1993-04-29
Abstract: Abstract of the Disclosure In a compression release engine brake, the starting point for the forward stroke of the slave piston is automatically adjusted when the engine brake is turned on, e.g., to remove the clearance which is typically provided between the slave piston and the associated internal combustion engine exhaust valve mechanism. Two elements in the engine brake move apart during the first forward stroke of the slave piston. Hydraulic fluid enters a chamber formed between these two members and is trapped there when the returning slave piston closes the aperture through which the fluid entered that chamber.  The return strokes of the slave piston are thus foreshortened.  The closing of the above-mentioned aperture by the slave piston constitutes the sole means by which hydraulic fluid is trapped in the chamber.  No other check valve element is required.
