A stent is then formed of the tooth crowns from the cast dental arch. The stent has incorporated into it a locating barrel. A drill head with a drill alignment arm is provided to the dentist for fixation to a dental drill hand piece. The kit of parts provided to the dentist includes the stent.with. its incorporated locating barrel. The drill alignment arm provided to the dentist for attachment to the drill head and a plurality of drills. By using the stent with its incorporated locating barrel, the dentist's drill is guided into the desired location by interaction of the pin of the drill alignment arm with the locating barrel in the stent. By additionally controlling the length of the drills, the location, axis and depth of the drill hole made by the dentist will exactly coincide with the designed location, depth and orientation of the implant.

Title: Method for in-situ analysis of formation parameters
Inventor: MEISTER MATTHIAS
IPC: E21B49/00
Filed: 2003-06-06
Abstract: A method of performing a formation rate analysis from pressure and formation flow rate data. Pressure and flow rate data are measured as fluid is withdrawn from a formation. Variable system volume is accounted for. The pressure and flow rate data are correlated using a multiple linear regression technique.  Time derivative terms related to pressure and flow rate are smoothed using a summation technique, thereby providing better correlations than using the time derivatives directly. Formation parameters comprising formation permeability, formation pressure, and fluid compressibility may be determined from the correlation.

Inventor: HUBLEY BRUCE
IPC: A63B69/36
Filed: 2004-12-30
Abstract: Apparatus 10 for a golf swing training device comprising a golf club 20 with a shaft 24 with a grip 22 at one end and a club head 26 at the other end of the shaft with a cup 12 attached to the face 14 of the club head with the cup opening on the front towards the intended target. The bore of the cup 12 conforms substantially to the diameter of the ball 28. In use, a ball 28 is placed in the cup 12 with the intention of releasing the ball from the cup at a desired point during the swing at a target. In practice, if during the back swing the cup 12 is incorrectly tilted, due to poor swing mechanics, the ball 28 will fall out. Also, if the bore of the cup 12 is not in alignment with the target line at the ball's 28 point of release the ball trajectory will be skewed from the target. As an additional element, the cup 12 can have a circumferential ridge 40 on the interior to impede the ball 28 from easily falling out and the cup can be removably attached at 36, 38 to the club face 14.

Title: Methods for the preparation of polyol esters that are light in color
Inventor: POPPE GEORGE B
IPC: C07C69/604
Filed: 2005-01-14
Abstract: The present invention is directed to a process of producing polyol esters possessing desirable composition and color. Preferably, such a process does not require molecular distillations or decoloration steps to yield a light-colored polyol ester composition. Materials that are dark in color are often produced during the esterification of polyols with vegetable oil fatty acids.  It has been discovered that the present process yields the desired ester products that are light in color. The present process comprises an esterification of a polyol, such as propylene glycol, and a fatty acid ester, such as a vegetable oil fatty acid methyl ester, in the presence of a catalyst and borohydride, wherein a polyol ester having a Lovibond color below about 0.6 Red and below about 1.5 Yellow is produced.

IPC: C12Q1/68
Filed: 2003-12-05
Abstract: Activated protein C (APC), prodrug, and/or a variant thereof may be used as an inhibitor of apoptosis or cell death and/or a cell survival factor, especial ly for stressed or injured cells or tissues of the nervous system including subjects with neurodegenerative disorders. Novel biological functions (e.g., neuroprotection) can be independent or separated from inhibition of clotting or inflammation, and other biological properties of APC (e.g., antithromboti c activity, ability to reduce NFkB-regulated gene expression). It can be used in the treatment of disease or other pathological conditions by at least inhibiting the p53-dependent and/or caspase-3-dependent pro-apoptotic signaling pathways in stressed or injured cells. Thus, APC, prodrugs, and variants thereof (e.g., APC protease domain mutants with reduced anti- coagulant activity) are prototypes of a class of agents for preventing apoptosis or cell death and/or promoting cell survival by direct action on brain cells. New protein C and/or APC variants with reduced anticoagulant activity may be selected thereby.
