Title: Method and apparatus for measuring total nuclear magnetic resonance porosity
Inventor: FLAUM CHARLES
IPC: G01V11/00
Filed: 1998-03-11
Granted: 2000-10-17
Abstract: A method and apparatus for measuring total nuclear magnetic resonance porosity of an earth formation traversed by a borehole is sensitive to fast relaxation times that can be associated with clay-bound water. The total porosity measurement includes, in addition to free fluid and capillary-bound porosity, the porosity of clay-bound water and microporosity. An oscillating magnetic field is produced within the borehole, according to a phase alternated sequence, such as the Carr-Purcell-Meiboom-Gill (CPMG) sequence or a similar pulse sequence, to induce signals in the volume of formation which are measurable by the NMR logging tool. A reduced echo spacing and improved signal-to-noise ratio allows the recovery of short T2 components. The spin echo signals are measured and a value is determined for each signal. The signal values are separated into a first set and a second set wherein the first set comprises the early-time echo signals and the second set comprises the remaining echo signals. The second set of echoes are sub-divided into a plurality of groups and a window sum value is generated for each group of the second set, thereby producing a plurality of window sums. An attribute of the formation is determined based upon the plurality of window sums and the value of each signal of the first set.

Abstract: The present invention relates to a fuze for a spin-stabilized projectile with a housing (2) within which there is a detonator carrier (9) that can pivot from a safety position into a firing position and which is secured in its safety position by a locking bolt (6). In order to make it possible to integrate a self-destruct unit into the fuze in a simple and cost-effective manner, the present invention proposes that the self-destruct unit (15) be arranged in the locking bolt (6) that is required to fix the detonator carrier (9) in its safety position, so that the self-destruct unit (15) is activated when the locking bolt (6) is moved from its starting position into an end position relative to the fuze housing by the inertial force that is generated when the projectile is fired, and then releases the detonator carrier (9).

Title: Bolt-on wear runner assembly for material handling/displacement apparatus
Inventor: RUVANG JOHN A
IPC: E02F9/28
Filed: 1998-07-21
Granted: 2002-04-09
Abstract: A wear runner assembly is attached to a surface of an excavating bucket and serves to protect a portion of the surface from abrasion wear during use of the bucket. The assembly includes a base member, a wear runner member, a pair of bolts and a pair of conical locking nuts. The base member is welded to the surface and has a pair of undercut slots that captively retain the head portions of the bolts, with the bolt bodies being transverse to the surface and projecting outwardly beyond the outer side of the base member. The wear runner member is mounted on the base member by moving the wear runner member toward the base member in a direction transverse to the surface in a manner causing the outwardly projecting bolt body portions to enter and be recessed within a pair of openings formed through the wear member, and also causing projections on the base member to be complementarily received within recesses formed in the wear runner member. Finally, conical locking nuts are threaded onto the bolt bodies recessed within the wear runner member openings to releasably hold the wear runner member on the base member.      The interlock between the base member projections and the wear runner member recesses prevents operating loads imposed on the assembly from moving the wear runner member relative to the base member parallel to the protected surface to thereby prevent the bolts from being sheared by such operating loads.

Title: Microchip drug delivery devices
Inventor: CIMA MICHAEL J
IPC: A61K9/00
Filed: 1997-07-02
Granted: 2005-01-11
Abstract: Microchips are provided, which control both the rate and time of release of multiple chemical substances and which allow for the release of a wide variety of molecules in either a continuous or pulsatile manner. In all of the preferred embodiments, a material that is impermeable to the drugs or other molecules to be delivered and the surrounding fluids is used as the substrate. Reservoirs are etched into the substrate using either chemical (wet) etching or ion beam (dry) etching techniques well-known in the field of microfabrication. Hundreds to thousands of reservoirs can be fabricated on a single microchip using these techniques. A release system, which includes the molecules to be delivered, is inserted into the reservoirs by injection, inkjet printing or spin coating methods. Exemplary release systems include polymers and polymeric matrices, non-polymeric matrices, and other excipients or diluents. The physical properties of the release system control the rate of release of the molecules. The reservoirs can contain multiple drugs or other molecules in variable dosages. The filled reservoirs can be capped with materials that either degrade, dissolve, or allow the molecules to diffuse passively out of the reservoir over time or materials that, upon application of an electric potential, oxidize to form soluble compounds or ions that dissolve into the surrounding fluids. Release from an active device can be controlled by a preprogrammed microprocessor, remote control, or by biosensors.

Title: Conveyor having a cushioned belt and high speed discharge capabilities
Inventor: BONNET HENRI
IPC: B65G19/02
Filed: 1998-04-16
Granted: 2005-03-08
Abstract: An automated conveyor sortation and item discharge system for conveying and discharging packages at high speeds. A conveyor assembly includes an elongate crowned conveyor belt (20), which conveys parcels in a longitudinal direction defined across slider beds (18) and across discharge stations. The parcels can take three different routes once they reach the discharge stations. They may be allowed to pass the discharge stations and continue to be conveyed by the crowned conveyor belt, or they can be selectively discharged off of the crowned conveyor belt and into discharge chutes located to either side of the substantially straight path of the crowned conveyor belt. Each of the discharge stations includes a selectively indexable fork member supporting a group of idling rollers. The parcels have sliding contact with the slider beds and "rolling contact" with the idler rollers. When a package is in the desired position, the fork member can be indexed to cause some of the rollers to move upwardly and inwardly. This causes the package to tilt about the top of the crowned conveyor belt until the package contacts a withdrawal roller opposing the conveyor belt from the raised rollers. The withdrawal roller draws the package into one of two chutes for sorting purposes.

The immunogens also comprise antibodies against the CCK-B/gastrin-receptor for passive immunization. The invention also concerns diagnostic methods for detecting gastrin-dependent tumors in vivo or from a tissue biopsy using the antibodies of the invention.
