Abstract: A seismic tool assembly for effecting a drill hole and enlarging a lowermost end thereof whereby an anchor can be set more securely therein. A drill bit is inserted through an opening in a stabilizer, which is mounted on a drill stop member inserted at least partially into the hole. The bit is then inserted through each of the stabilizer and the drill stop member, to attain a drilling position at the lowermost end of the hole. The lower end of the bit has a cutting portion having a cutting radius greater than that of the bit body whereby, when the bit is inserted fully into a lowermost end of the hole and rotated, the cutting portion enlarges the lowermost end, whereby flanged portions of an anchor will rest within the enlarged area, retaining the anchor in place. An upper end of the stabilizer has a narrower opening for receiving the insertion of the bit body therein and the lower end of the stabilizer has an opening greater than that of the upper end, so as to permit limited tilting movement of the bit body within the stabilizer during the drilling process to further enlarge the lowermost end of the hole.

The processes can be used for the selection of safe NMDA receptor an-tagonists for the treatment or prevention of a hu-man disorder that lowers the pH in a region of af-fected tissue.

Abstract: A high efficiency combined cycle internal combustion and steam engine includes a cylinder having a piston mounted for reciprocation therein with an internal combustion chamber outward of the piston, a fixed cylinder cap sealingly and slidably mounted within the piston and a steam expansion and recompression chamber inside the piston adjacent the cylinder cap. The cylinder cap can be unheated or heated externally to reduce condensation of steam entering the steam chamber from a steam generator fired by waste combustion heat. After a steam exhaust valve closes at the top center position, residual steam is recompressed during an inward stroke of the piston up to admission pressure prior to admitting the next charge of steam. A wrist pin that is connected to an inner part of the skirt of the piston and located inwardly of the cylinder cap is coupled to a connecting rod that is secured at its inner end to a crankshaft. One valve or a pair of retractable steam inlet valves connected in series within the cylinder cap inside the piston act in cooperation with steam recompression and a variable clearance volume to achieve an effective zero steam chamber clearance and a gain in mean Rankine cycle temperature to maximize efficiency. The amount of steam admitted each outward stroke is continuously regulated to reduce fuel consumption. Engine coolant can be evaporated in an engine cooling jacket to form steam that is superheated in a combustion exhaust manifold.

Title: Configurable depth-of-field raycaster for medical imaging
Inventor: SCHELLENBERG TONY
IPC: A61B8/13
Filed: 2011-04-18
Abstract: A method for volume ray casting is provided. For each pixel of a 2D image placed in a view plane a ray of sight is projected through a volume determined by a plurality of voxels of a volumetric dataset indicative of an object. A plurality of sampling points is determined along each ray of sight such that a distance between two consecutive sampling points is larger at a larger distance to the view plane. At each sampling point a color value and a transparency value is determined in dependence upon voxels in proximity of the sampling point and a lighting calculation, wherein for the lighting calculation a first lighting model and a second lighting model are used in dependence upon a distance of the sampling point to the view plane. For each ray of sight a final color value is determined by compositing along the ray the color values and the transparency values. The final color value of each ray corresponds to a pixel value of the 2D  image. The color and the transparency value of a sampling point are composited with the color and transparency value of a previous sampling point before determining the color and transparency value of a following sampling point. The compositing is stopped when the composited transparency value is within a predetermined range less than a value indicative of opacity.
