Publication number: 20040200810Abstract: A coolant tube and electrode are adapted to mate with each other to align the tube relative to the electrode during operation of the torch. Improved alignment ensures an adequate flow of coolant along an interior surface of the electrode. In one aspect, an elongated body of the coolant tube has a surface adapted to mate with the electrode. In another aspect, an elongated body of the electrode has a surface adapted to mate with the coolant tube. The surfaces of the tube and electrode may, for example, be flanges, tapered surfaces, contours, or steps.Type: ApplicationFiled: April 11, 2003Publication date: October 14, 2004Applicant: Hypertherm, Inc.Inventors: Aaron D.

Patent number: 6777190Abstract: Assay for detecting the amount or presence of target ligand in a sample. The assay includes a ligand analogue conjugate having a linkage site and a binding site, a ligand receptor, and a sample. The assay includes the steps of providing at least one crosstalk inhibitor. This inhibitor, under assay conditions, competes with the linkage site of the ligand analogue conjugate for binding to the ligand receptor, and does not compete with the binding site of the ligand analogue conjugate for binding to the ligand receptor. In the invention, the assay is performed for the target ligand in the presence of a sufficient amount of the crosstalk inhibitor to reduce the amount of binding of the linkage site of the ligand analogue conjugate to the ligand receptor. The invention also features a method for identifying crosstalk inhibitors, and the crosstalk inhibitors themselves.Type: GrantFiled: May 11, 1994Date of Patent: August 17, 2004Assignee: Biosite, Inc.Inventors: Kenneth F.

Patent number: 6715526Abstract: A cubicle door is comprised of first and second brackets for wrapping over the top edges of a cubicle panel on opposite sides of the entry way. A roller blind has a proxiinal end hinged to the first bracket, and a distal end which is removably supported on a support attached to the second bracket. The end of the roller blind is received in either one of perpendicular grooves on top of the support. The grooves allow the roller blind to meet the second support at different fixed angles to fit the shape of the entry way. Alternatively, a rotatable turret with a notch is arranged on the second bracket. The roller blind is received in the notch, and the second bracket may be oriented at different angles relative to the roller blind by rotating the turret.Type: GrantFiled: December 30, 2002Date of Patent: April 6, 2004Inventors: Roderick A.

Patent number: 6076611Abstract: A depth control system for controlling the working depth of an implement. The depth control system includes a monitor having an automatic mode of operation and a manual mode of operation wherein the automatic mode of operation provides preset, discrete working depth positions for the implement, and the manual mode of operation provides a continuous range of selectable positions. The monitor receives input signals from a position sensor mounted to the frame of the implement, and the position sensor includes a movable arm in sliding contact with an actuator arm mounted to a rock shaft of the implement whereby movement of the rock shaft and actuator arm causes the movable arm of the position sensor to move and provide different input signals to the monitor corresponding to the different positions of the rock shaft. The monitor provides an output signal to a hydraulic valve for controlling one or more hydraulic cylinders which actuate the rock shaft in movement to position the working depth of the implement.Type: GrantFiled: December 17, 1998Date of Patent: June 20, 2000Assignee: AGCO CorporationInventors: Dennis L.

Patent number: 5939272Abstract: Assay methods for performing non-competitive ligand-receptor assays, where said assays provide a sensible result when the target ligand identified by the assay is present at a concentration greater than a defined threshold concentration. The threshold concentration can be selected to be the upper limit of a normal range of values for a target ligand in a sample, so that an assay in accordance with the invention provides a sensible result only when the target ligand is present at elevated levels.Type: GrantFiled: June 11, 1997Date of Patent: August 17, 1999Assignee: Biosite Diagnostics IncorporatedInventors: Kenneth F.
