Publication number: 20020078737Abstract: An apparatus and related method for measuring the presence or degree of stratified flow in a two-phase flow is disclosed. A first speed of sound for the fluid flowing through the pipeline is measured for an ultrasonic signal that would reflect from stratified flow, if present. A second speed of sound is measured at a location that would not reflect off the stratified flow. A difference in these two measurements indicates the presence of stratified flow. The level of stratified flow can be determined based on the magnitude of the difference. Because this method is so sensitive to changes in the amount of stratified flow, it is more reliable than previously known methods.Type: ApplicationFiled: January 4, 2002Publication date: June 27, 2002Inventor: Klaus Joachim Zanker

Publication number: 20020078740Abstract: In detecting which transmitter of several of transmitters has transmitted a radio signal based on digital data from an RF circuit, a main controller of a receiver consecutively sends activation commands to each of several control circuits such that only one of the control circuits is activated at a time.

As a result, the power consumption is reduced, and the transmitter that transmitted the radio wave is accurately detected.Type: ApplicationFiled: September 20, 2001Publication date: June 27, 2002Inventors: Noboru Imao, Michiya Katou, Yasuhisa Tsujita

Publication number: 20020078748Abstract: In order to compensate for a drop in sensitivity at high rotational speeds, an acceleration sensor having an inductive measuring head (T) which cooperates with a moving Ferraris disk (F) essentially over a main magnetic field and which supplies an acceleration-dependent variable (Vdet; V&agr;) is expanded by an additional DC magnetic field excitation circuit (13, 14, IK, RK) with a means for driving the latter with the effect that the additional DC magnetic field acts in a compensating fashion on an eddy-current DC field, starting from a relatively high rotational speed (&ohgr;) of the Ferraris disk (F).

A control signal (V&ohgr;), dependent on rotational speed, which both can be generated outside the sensor via a characteristic curve, and can be derived in the form of a control loop from the sensor signal (V&agr;), serves as a drive.Type: ApplicationFiled: July 31, 2001Publication date: June 27, 2002Inventors: Franz Bauer, Gabriel Daalmans

Publication number: 20020078776Abstract: The invention relates to a worm wheel for use in a reduction gear, for example, and to a machine and a method for forming the same. The worm wheel includes a tooth having a tooth crest. At least the teeth are formed by injection molding a synthetic resin. The tooth crest includes a trace formed along a parting line as a result of the injection molding process. The trace does not exist on a surface of action of the tooth. The invention is suitable for applications demanding high contact gear accuracies.Type: ApplicationFiled: December 26, 2001Publication date: June 27, 2002Inventors: Kikuo Yamashita, Tetsuya Minamiguchi, Takanori Kurokawa, Michitoshi Mitsumaru

Publication number: 20020078777Abstract: A gear assembly includes a dampening layer disposed intermediate to a face and a backing. The dampening layer is preferably injection molded between the face and the backing through one or more openings in the backing. The dampening layer minimizes noise and vibrations associated with gear assemblies and interfaces and reduces the transmission of noise and vibrations through the gear assembly.Type: ApplicationFiled: December 27, 2000Publication date: June 27, 2002Inventors: David E.

Publication number: 20020078778Abstract: A robot drive assembly for moving a working tool in x, y, z and theta directions comprising three independent, coaxially nested tubes, each tube being driven around a common central axis by drive belts attached to separate drive motors located in a mounting flange associated with the outermost tube. The motors, and the tubes which they drive, provide horizontal rotary motion to a robot arm attached to the upper end of the outer tube and the wrist and elbow of that arm. A fourth motor controls vertical motion of the whole assembly. The robot system also includes motor position adjustment structure and belt tension structure designed for ease of use and to eliminate movement of tensioned components once locked in position.Type: ApplicationFiled: October 19, 2001Publication date: June 27, 2002Applicant: INNOVATIVE ROBOTIC SOLUTIONSInventors: Gaylen Grover, Dennis Wightman, Tomas Melendez

Publication number: 20020078779Abstract: Conventional positioning devices in which a body is displaceable in a plane and rotatable by means of three drives have the drawback that at least one of the drives is displaced together with the body, whereby these apparatus are relatively heavy and sluggish. In the case of the positioning device according to the invention, three straight guide elements, arranged radially, are rigidly connected to the body. Each guide element is accepted in a linear bearing in a longitudinally displaceable way, and each linear bearing is disposed on a separate rotor in a way pivotable about a pivot axis directed perpendicular to the plane. Through independent displacement of the linear bearings on a common circular path, the body can be shifted and rotated as desired in a region. This construction has the advantage that it is built simply and that it is able to execute quick and precise positioning movements in particular owing to small masses in motion.Type: ApplicationFiled: December 21, 2001Publication date: June 27, 2002Applicant: Leichti Engineering AGInventors: Andreas Scheidegger, Ralph Liechti
