Title: Hand-held stent crimper
Inventor: DAVIS HORACE R
IPC: A61F2/06
Filed: 1997-07-28
Abstract: A stent crimper is provided for loading a stent onto a catheter in order to provide a stenting assembly that is suitable for use in procedures in conjunction with percutaneous transluminal angioplasty and percutaneous transluminal coronary angioplasty catheters. The crimper has a stent holding member or sheath which supports the stent by its exterior surface so that a balloon of a catheter can be slid within the stent. An elongated wrapping member or belt winds around the sheath. By properly manipulating the belt, the belt applies generally cylindrical radially directed forces onto the sheath and thus onto the stent within the sheath, as well as the balloon beneath the stent, in order to crimp the stent onto the balloon. A procedure is also illustrated by which a stent is crimped onto the balloon by a hand-held crimper which can be discarded after stent delivery and crimping has been completed.

Inventor: SEEGOPAUL PURNESH
IPC: C01B31/30
Filed: 1997-09-11
Abstract: In order to eliminate the oxygen sensitivity of chromium carbide and vanadium carbide particles, vanadium carbide and chromium carbide particles are formed by carburizing a precursor compound at a elevated reaction temperature of about 950° C. Initially, the precursor compound is heated in an inert nitrogen-containing gas to the reaction temperature. Once the reaction temperature is achieved, hydrogen and a carbon-containing gas such as methane or ethylene are used to conduct the carbonization. After the carbonization has been completed, the carbonizing gas is then replaced with an inert nitrogen-containing gas and the product allowed to cool down. The carbonization cycle is adjusted so that the oxygen level is kept to less than 0.35%, while the nitrogen level is kept at about 2%. Powders produced from this process show minimal or no oxygen pickup when exposed to ambient air.

Patent CA-2218984-A1 (CA)
Title: Cleaning fluid apparatus and method for continuous printing ink-jet nozzle
Inventor: PAROFF PAUL J
IPC: B41J2/165
Filed: 1996-04-09
Abstract: A fluid (liquid or water) wash (46) is used to clean the front surface of an ink jet printer cartridge (17). In addition, a nozzle plate (24) that overlies the nozzle shields the nozzle array (23) from the splatter of ink (32). In ink jet printers, ink droplets are propelled from an array of orifices in a nozzle plate in the printer head.   During the ink droplet ejection, ink is sprayed or deposited around the orifices. The ink droplets are deposited on a paper web (14) adjacent the nozzle and mist from the droplets drifts back to coat the face of the nozzle plate.      Some ink seeps behind the nozzle plate (24) onto the array of nozzle orifices (23).      The ink coating attracts particles that tend to clog the nozzle orifices. The ink coating is washed away by fluid streams (46) that flow over the nozzle surface and in some embodiments flow over the nozzle orifices themselves. The fluid (46) may be water, ink or other liquid that is channelled across the nozzle surface, or the fluid may be an air stream that blows across the nozzle surface.

Title: Data communication network with highly efficient polling procedure
Inventor: SCHIELTZ STEVEN W
IPC: H04N7/18
Filed: 1996-05-17
Abstract: A local area data network (26) interconnects devices (12, 14, 20, 30) which make up a video surveillance system (10). The devices attached to the local area network are divided into distinct classes (12, 14, 30) which are polled with different degrees of frequency. Devices are dynamically reassigned from class to class depending on each device's current requirements for network access. Group polling is also employed, with resolution of contention by means of a probing algorithm.  Negative responses to polling messages are formed as a series of line transitions that require less time than transmission of a single data byte. Polling messages have a distinct length in terms of bytes that is shorter than any other message transmitted on a network. Polled devices (12, 14) are permitted to transfer data directly to peer devices in response to polling messages.

Patent CA-2241660-A1 (CA)
Title: Low wattage, high flow electrical control valve
Inventor: CARROLL JOHN B
IPC: B60T13/66
Filed: 1998-06-26
Abstract: The invention provides an electrically activated valve assembly for control of a fluid. It has a diaphragm with a control chamber on one side and a flow barrier on the second side. Portions of a first flow passage and a second flow passage are on the second side of the diaphragm, with the flow barrier between them. When the control chamber has a relatively high pressure, the diaphragm is pressed against the flow barrier, isolating the first flow passage from the second flow passage. When the control chamber has a relatively low pressure, the diaphragm moves away from the flow barrier, so flow may occur between the first flow passage and the second flow passage. The position of the diaphragm is determined by pressure in the control chamber so the pressure in the control chamber controls the fluid flow connection between the first flow passage and the second flow passage. The valve also has an electrically activated valve responsive to an electrical signal to control pressure in a flow passageway to the control chamber so that when the electrically activated valve is energized, the control pressure is changed, so the electrically activated valve controls the fluid flow connection between the first flow passage and the second flow passage.

Abstract: The present invention is a method of detecting reaction in blood caused by the presence of a foreign substance in the blood, comprising the steps of: establishing a potential across a predetermined spatial volume;  passing a first portion of the blood through the predetermined spatial volume; substantially continuously measuring the potential across the predetermined spatial volume over a first predetermined period of time; comparing the measured potential with a baseline; and calculating the total volume of solids in the first portion of the blood as a function of a total absolute deviation of the measured potential from the baseline. The same procedure is then followed with a second portion of the blood, after it has been exposed to the substance whose reaction is being determined. The two calculations are then compared, with a positive reaction being indicated when the two measured solid volumes are measurably different. The baselines are preferably dynamic baselines, and are determined with reference to the starting point of a sharp rise in the measured potential.
