Title: Diagnostic gas monitoring process
Inventor: MALCZEWSKI MARK LEONARD
IPC: G01N1/22
Filed: 1991-11-25
Granted: 1995-10-03
Abstract: A process for the continuous analysis of trace contaminants in a process gas of O2, N, Ar or H2.  A sample of the process gas is passed through a plurality of analyzers with each dedicated to detect the presence of a predetermined trace contaminant and to provide an output signal corresponding to the level of trace impurity detected.  A status signal is generated representative of preselected parameters of analyzer operation.  The output and status signals are converted by a computer into data values.  A rule based program provides a problem analysis to identify distinct problems based on the examination of the data values.  The rule based program is executed by a separate command program which matches the problems identified by the rule based program with remedial actions to remedy erroneous conditions of analysis.

Granted: 1999-10-12
Abstract: A centrifugal cleaner has a cleaning quotient greater than .5 and a rejects by weight performance value typically of less than 5% (e.g. less than 2%) for conventional paper pulp furnish. The tangential inlet nozzle to the side wall near the top of the cleaner body has a non-circular -- preferably D-shaped -- inlet opening so as to provide enhanced throughput. The cleaner body side wall includes an upper portion that is conical and extends past the top nozzle, a generally cylindrical center portion which significantly increases retention time within the cleaner, and a conical bottom portion in which a bottom nozzle is operatively disposed. The bottom nozzle has a rejects opening therein with a diameter that is about 25-45% (preferably roughly 1/3) of the internal diameter of the side wall at the opening, and is about 25-45% (preferably roughly 1/3) of the internal diameter of the top nozzle. The bottom nozzle may have an insert with an interior three-dimensional parabolic surface terminating at its bottom in the rejects opening, or may comprise a flat plate with a main top surface perpendicular to the top nozzle. During use rejects particles collect on the flat plate top surface and define a generally parabolic configuration.

Title: Wire transport apparatus
Inventor: DE GROOT JOHAN WILLEM HERMAN
IPC: B65H51/10
Filed: 1992-01-06
Granted: 1998-05-12
Abstract: A wire transport apparatus has a pair of rollers having opposed peripheral running surfaces which at their nip contact the wire to drive it, one of said rollers being driven.  The driven roller is mounted on an arm swingable about a pivot axis.  The arm also carrying a coupling pulley connected to the driven roller to drive it in rotation.  The coupling pulley is itself driven in rotation by an endless flexible element whose tension tends to cause said driven roller to apply load to said wire.  In order that variation of the tension in belt also adjusts the normal force applied to the wire by the driven roller, the pivot axis is parallel to the direction of wire travel, and the driven roller and the coupling pulley are on a common rotational axis perpendicular to the pivot axis, at different distances from the pivot axis.          Excessive force on the wire is avoided, and wear is minimized.

Title: Power amplifier device comprising a plurality of feedforward distortion compensating circuits in parallel
Inventor: SAKAMOTO HIRONORI
IPC: H03F3/68
Filed: 1993-01-15
Granted: 1996-08-20
Abstract: For supply to first and second feedforward distortion compensating circuits 33(1), 33(2) connected in parallel, a two-divider 31 divides into signals of a common phase and a common amplitude an input radio frequency signal supplied to an input terminal 11.  A two-combiner 35 combines component outputs of the feedforward circuits in inphase as an amplified output signal which is supplied to an output terminal 13.  In general, N feedforward circuits (N being an integer not less than two) are connected in parallel and are supplied with the input radio frequency signal through an N-divider.  Component outputs of the feedforward circuits are combined in inphase as the output signal by an N-combiner.  Alternatively, the input radio frequency signal is divided into signals of a predetermined phase difference and of a common amplitude by the N-divider.          In this case, the component outputs of the feedforward circuits are combined in a phase of cancelling the predetermined phase difference by the N-combiner.
