Abstract: A contact tip for arc welding is split into a tip main body (1) and a tip distal end portion (2), and is removably fitted by a screw method or a taper press-in method. The tip main body (1) is made of brass, copper, aluminum, chromium copper, zirconium copper, zirconium chromium copper or phosphor bronze, and the tip distal end portion (2) is made of copper, chromium copper, zirconium chromium copper, silver tungsten, copper tungsten, alumina dispersed copper, beryllium copper or nickel beryllium copper, in order to extend life of the contact tip and to reduce the total cost. In this instance, brass is a particularly suitable material for the tip main body, and chromium copper or zirconium chromium copper is a suitable material for the tip distal end portion (2). Of the wire passage of the tip main body (1), the passage diameter of at least the tip distal end portion side is within the range of 1.03 to 1.50 times the wire diameter, and the wire passage diameter of the tip distal end portion (2) is within the range of 1.03 to1.25 times the wire diameter. According to this arrangement, the wire can be smoothly inserted, electric current can be reliably supplied, and positioning error of arc welding can be prevented.

Patent CA-2239364-A1 (CA)
Inventor: SCHROEPPEL EDWARD A
IPC: A61N1/362
Filed: 1996-12-12
Abstract: An apparatus for evaluating heart rate variability of the heart of a person in order to forecast a cardiac event. A cardiac stimulator receives heart beat signals from the heart and determines a measurement of heart rate variability based on statistical data derived from the heart beat signals and sensing data derived from a sensor. This measurement of heart rate variability is compared with previously stored heart rate variability zones defining normal and abnormal heart rate variability. These zones are modifiable after the occurrence of a cardiac event. Once a cardiac event is detected, a pathway is computed which extends from a generally normal heart rate variability condition to an abnormal heart rate variability condition. Subsequent measurements of heart rate variability are compared with this pathway. Selective therapy regimes are initiated depending on the measurement of heart rate variability.

Title: Real-time gas-chromatography mass-spectrometry trace vapor detection
Inventor: ARNOLD JAMES T
IPC: G01N30/16
Filed: 1997-10-14
Abstract: A gas flow distribution system accumulates a sample from a sample bearing carrier gas in a micro-accumulator, delivers it using a carrier gas to a gas-chromatography column, and supplies a carrier gas to the gas-chromatography column to facilitate separation of the sample into sample components and transport the sample components to a mass spectrometer for trace vapor detection and analysis or testing in real time. The system is made of inert components and configured to have low dead volume for improved performance and accuracy of detection. External valves are employed for easy management and balance of the flow in the system to minimize operation time and facilitate continuous accumulation, delivery, and testing of the sample. The delivery of the sample to the gas-chromatography column using an electrically heated cold trap as the micro-accumulator can be performed extremely fast. By further combining the sample accumulation phase and the sample testing phase, real-time operation of trace vapor detection is achieved. Because the step of delivering the sample to the gas-chromatography column is performed quickly, the accumulation of the sample can resume quickly and is nearly continuous for improved efficiency.
