Inventor: FOSTER MARTIN C
IPC: F42B3/13
Filed: 1997-12-29
Abstract: A semiconductor bridge igniter device (10) having integral voltage anti-fuse protection provides an electric circuit including a firing leg and, optionally, a monitor leg. The firing leg comprises semiconductor pads (14a, 14b) separated and connected by a bridge (14c) and having metallized lands (16a, 16b) disposed over the pads (14a, 14b) so that an electrical potential applied across the metallized lands (16a, 16b) will cause sufficient current to flow through the firing leg of the electric circuit to release energy at the bridge (14c). A dielectric layer (15) is interposed within the firing leg and has a breakdown voltage equal to a selected threshold voltage (Vth) and therefore provides protection against the device functioning at voltages below the threshold voltage (Vth). A continuity monitor leg of the electric circuit is comprised of either a fusible link (34) or a resistor (36) disposed in parallel to the firing leg.

Abstract: In our research, two commercially available compounds, 3-amino-1,2,4-dithiazole-5-thione (1) and xanthane hydride (2), and their derivatives 3-6 are found to be potential sulfur-transfer reagents. The efficiency and optimization of these new sulfur-transfer reagents were investigated by solid-phase synthesis of dinucleotide and oligonucleotide phosphorothioates. The results show that both compounds (1) and (2) are highly efficiency sulfurizing reagents, and better than 99 %  sulfur transfer efficiency can be achieved at each step. In contrast to Beaucage reagent, these novel sulfur-transfer reagents are very stable in various solvents, and are available in bulk quantities at low cost.  Due to these advantages, compounds (1) and (2) can be considered alternatives to Beaucage reagent, especially in large-scale preparation of oligonucleotide phosphorothioates. Furthermore, compounds (1) and (2) were modified to enhance their solubility in acetonitrile. Three types of structure, as described as Formulae (I), (II) and (III), are considered as potential efficient sulfur-transfer reagents based on our results.

Title: Method and system of encoding and processing alternative healthcare provider billing
Inventor: GIANNINI JO MELINNA
IPC: G06F19/00
Filed: 1997-10-30
Abstract: A system (10) for encoding and encompassing healthcare provider billing, more particularly, a computer assisted network for encoding, documenting and processing claims (18) for payment of specific procedures by alternative therapy providers (12), grouped geographically and by specialty. The system (10) employs a computer accessing three main databases (14, 16, 20) for identifying, encoding and calculating the average cost for provider services (58). A resulting Alternative Billing Code (ABC) is produced which can be compared and correlated with insurance industry standard codes (40). The ABC  is an assembly of a series of terms and sub-terms from databases (14, 16, 20), namely Alternative Practice Type (APT) (14), Standard Alternative Procedure Descriptions (SAPDs) (16), Provider Data (PD) (20) and RVU (Relative Value Unit) databases. Each provider specialty includes its own listing of treatments which are turned into RVUs, thus establishing a sequence of treatment fees and charges. The APT code and SAPD code are stored in a PD file including average claim costs of all providers as categorized by a predetermined grouping, which with the PD create the ABC as a comprehensive, single code representing all elements of treatment incident to a patient visit. Claims (18) for payment are submitted and translated into an appropriate code for determination of payment under the present system.

Title: Drive and shear mechanism for downhole tool
Inventor: WRIGHT ANDREW J
IPC: E21B23/01
Filed: 2000-08-04
Abstract: An anchoring device for anchoring an oil well tubing string within an oil well casing. The device generally comprises a drive mandrel and an anchor mandrel. The drive mandrel has an upper end and a lower end, with the upper end releasably securable to an oil well tubing string. The anchor mandrel has an upper end that is releasably securable to the drive mandrel. The anchor mandrel is selectively engagable and disengagable with the interior surface of an oil well casing through the use of a plurality of rotatable slips. The slips have a gripping surface to contact and adhere to the interior surface of the oil well casing such that when the anchor mandrel is rotated in a first direction the slips are rotatably deployed to an engaged position with the gripping surfaces in contact with the interior surface of the oil well casing. Rotation of the anchor mandrel in a second opposite direction causes the slips to be rotatably retracted from their engaged position to a disengaged position such that the gripping surfaces are withdrawn from contact with the interior surface of the oil well casing. A shear mechanism may be employed between the drive and anchor mandrels to alow for controled separation of the mandrels under pre-determined tensile loading.
