Appl. No.:

09/114458

Inventors:

James C. Wang - Norton MA
Albert Chin - Newton MA
James B. Daigle - Morgan Hill CA
Douglas J. Daniels - Mendon MA

Assignee:

Boston Scientific Corporation - Natick MA

International Classification:

A61B 500

US Classification:

600585

Abstract:

Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmitted to the distal end without substantial whipping, even if the implement follows a long and tortuous pathway. Applications include medical guidewires, catheters, and driveshafts.

International Classification:

G01W 100

US Classification:

73170A

Abstract:

A low-cost floating drifter adapted to accurately follow near-surface ocean currents and transmit periodically to monitoring satellites data and position-determining information. Global tracking of ocean currents is made economically and scientifically feasible by the use of large numbers of such drifters. The drifter includes a floating surface buoy in the approximate shape of an oblate spheroid and containing an electronic system, a slotted plane antenna, transmitter, sunrise and sunset detector, environmental sensors, buoy hull strain sensor and battery power supply. The surface buoy is stabilized and induced to follow ocean currents by a drogue suspended from the bottom center surface. The drogue includes a wire-cored buoyant rope of up to hundreds of meters in length and weighted to a slight negative buoyancy. The drogue may also include an elongated cylindrical sock of substantially greater diameter than the rope.

Abstract:

Barium titanate based dielectric compositions having the general formula Ba. sub. (1-x-x'-x") Pb. sub. x Ca. sub. x' Sr. sub. x" Ti. sub. (1-y-y'-y") Sn. sub. y Zr. sub. y' Hf. sub. y" O. sub. 3, wherein x, x', x" and y, y', y" represent mole fractions of the divalent and tetravalent cations and x and x' have independent value greater than 0. 01 and less than 0. 3 and x", y, y' and y" have independent values greater than zero and less than 0. 3, such that the sum (x+x'+x") is greater than 0. 01 and less than 0. 4 and the sum (y+y'+y") does not exceed 0. 4. Regardless of the specific composition selected, the products of the invention have a mean primary particle size in the range of 0. 05 to 0. 4 microns with a very narrow particle size distribution. The products are dispersible so that the mean particle size determined by image anaylsis and by sedimentation are comparable.

International Classification:

G06F 1120

US Classification:

371 68

Abstract:

A fualt-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units. Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner. Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units. The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units. Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit. The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

International Classification:

C08K 310

US Classification:

524409

Abstract:

This disclosure relates to a process for preparing co-pelletized submicron pigment powder/polymer pellets in a dry drum pelletizing process using a thermoplastic polymer as seed pellets. Also disclosed is a process for using the co-pelletized product either for formation of masterbatch or for directly introducing at least one pigment into thermoplastic media.

International Classification:

C04B 3549

US Classification:

501138

Abstract:

The present invention relates to a variety of dispersible doped multi-component BaTiO. sub. 3 based powder compositions. The primary particles of each of the products are substantially spherical, have sizes in the range of 0. 05 to 0. 4 microns and have narrow size distributions. Further, the compositions of the primary particles, forming each powder, are comparable. The amount of dopant oxide or oxides contained in the powder composition ranges from between greater than 1 to 10 mole percent. Regardless of the dopant or dopants utilzied, all the powder compositions of the present invention are identified by the same unique morphological characteristics.

International Classification:

C10J 316

US Classification:

48202

Abstract:

Solid or liquid organic materials are converted to high BTU gas with little or no undesirable char formation by reaction with water at or above the critical temperature of water and at or above the critical pressure of water to achieve the critical density of water. The reaction can be conducted either in the presence or in the absence of a catalyst.
