Title: Method and apparatus for plasma mass analysis with reduced space charge effects
Inventor: DOUGLAS DONALD J
IPC: H01J49/26
Filed: 1995-10-31
Abstract: A method of analyzing an analyte contained in a plasma, in inductively coupled plasma mass spectrometry (ICP-MS). A sample of the plasma is drawn through an orifice in a sampler, then skimmed in a skimmer orifice, and the skimmed sample is directed at supersonic velocity onto a blunt reducer having a small orifice therein, forming a shock wave on the reducer. Gas in the shock wave is sampled through an offset aperture in the reducer into a vacuum chamber containing ion optics and a mass spectrometer. This reduces space charge effects, thus reducing mass bias and also reducing the mass dependency of matrix effects. Since the region between the skimmer and the reducer can operate at about 0.1 Torr, which is the same pressure as that produced by the roughing pump which backs the high vacuum pump for the vacuum chamber, a single common pump can be used for both purposes, thus reducing the hardware needed. In a simplified version, the skimmer can be replaced by a small beam blocking finger which extends across a line of sight between the sampler and reducer orifices and occludes the reducer orifice from the sampler orifice.

Abstract: An operating shaft which provides compensation axial and spatial misalignment between a rotatable component mounted within an enclosure and a rotating means generally outside the enclosure. The operating shaft has a first end which is dimensioned to be slidably received within a receiving portion of the rotating means such that the shaft is maintained in a fixed angular position with respect to the rotating means. The shaft is axially slidable with respect to the rotating means such that it will provide compensation for axial misalignment between the rotatable component and the rotating means. The shaft has a second end formed to engage the rotatable component such that a rotation of the rotating means will produce a corresponding rotation of the rotatable component. The shaft also has a spatial compensation device which is integrally formed in the shaft between its first and second ends. The spatial compensation device provides compensation for spatial misalignment between the axis of the rotatable component and the axis of the rotatable means. This is accomplished by creating a compensating angle between the first and second ends which permits the shaft to be rotated about its axis while maintaining the compensating angle.

Abstract: Blood is circulated through a multiple lumen catheter (10) which connects between a vein of a patient, and the blood treatment device. The catheter and the lumens (14, 16) thereof each define distal ends which are positioned within the vein. By this invention, one withdraws blood from the vein through one of the lumens at a flow rate of at least about 200 ml./min. while also inserting blood into the vein through another of said lumens at a similar flow rate. The distal ends of the lumens are longitudinally spaced from each other by no more than about 5 mm. It has been found that the following advantages can be achieved by this method: less clot formation coupled with low direct blood recirculation, and longer catheter survival. Also, the catheter works well in either direction of blood flow through the respective lumens.

Patent CA-2227271-A1 (CA)
Inventor: REED COKE S
IPC: H04L12/56
Filed: 1996-07-19
Abstract: A network or interconnect structure utilizes a data flow technique that is based on timing and positioning of messages communicating through the interconnect structure. Switching control is distributed throughout multiple nodes in the structure so that a supervisory controller providing a global control function and complex logic structures are avoided. The interconnect structure operates as a "deflection" or "hot potato" system in which processing and storage overhead at each node is minimized. Elimination of a global controller and buffering at the nodes greatly reduces the amount of control and logic structures in the interconnect structure, simplifying overall control components and network interconnect components and improving speed performance of message communication.

Abstract: The invention concerns a floor covering made up of pentagonal concrete moulded parts (F1) which fit together with joints between them. In order to give a floor covering of this kind an appearance similar to that of a floor covering made of irregularly shaped natural stones, while at the same time ensuring that the moulded parts are easy to manufacture and easy to lay, the invention calls for each part to have two adjacent straight sides (1, 2) of equal length with an obtuse angle between them, two concave sides (3, 4) of the same length and with the same curvature on each side of the two straight sides and, between the two concave sides, a convex side (5) twice as long as the concave sides (3, 4) and with the same curvature as the concave sides. Each set of three parts forms a group, the straight sides (1, 2) fitting against each other to form a star-shaped joint (6). The outwards-facing convex side (5) of each group of three fits into the concave sides of the adjacent groups of three and vice versa.

Title: Process and device for checking the solidity of vertically anchored masts
Inventor: ROCH MATHIAS
IPC: G01L5/00
Filed: 1997-04-16
Abstract: In a process for checking the solidity of vertically anchored masts, rising traction and compression forces F which can be sensed by a force sensor are introduced into the mast above its anchoring in order to load the mast with opposite bending moments.      At least one displacement sensor supported against the mast above its anchoring measures the lateral deflection S of the mast caused by the bending moments. The measurement values for the force F and deflection S generated by the force and displacement sensors are separately processed in an evaluation unit relative to the functions f = F(S) or f = S(F), based on the curve of functions f1 in the event of a pressure load and on the curve of functions f2 in the event of a traction load. If the rising part of the curve of functions f1 deviates from the rising part of the curve of functions f2 or from corresponding reference values when the mast is elastically deformed, this is taken as a criterion for crack formation in the mast (1). A device for checking the solidity of vertically anchored masts has a force application unit (5) for applying rising traction and compression forces F to the mast (1) which can be sensed by a force sensor (7) and for loading the mast with opposite bending moments, at least one displacement sensor (8) which can be supported against the mast (1) above its anchoring (2) to measure the lateral deflection S of the mast caused by the bending moments, and an evaluation unit (9) to process the measurement values for the force F and deflection S generated by the force and displacement sensors (7, 8) relative to the functions f = F(S) or f = S(F). The evaluation unit determines if the rising part C of the curve of functions f1 deviates from the rising part of the curve of functions f2 or from corresponding reference values and considers this as a criterion for crack formation in the mast.
