Abstract: A method and a circuit arrangement having a device for measuring the depletion layer temperature of a GTO are specified. In this case, a measurement current (I M) is impressed in the gate circuit, and the voltage (U GR) between the cathode and gate is measured, with an applied measurement current (I M), after the transient turn-off processes have decayed. This voltage (U GR) is at this time dependent on the depletion layer temperature of the GTO. It thus becomes possible to measure the depletion layer temperature directly on the element, that is to say without circuitous routes via a heat sink temperature and calculation of the thermal resistance or the like, and during operation, continuously, and in consequence to monitor and control the stress level on the GTO precisely.

Title: Apparatus for measuring mass flow
Inventor: OLESEN HENRY TOFTDAHL
IPC: G01F1/30
Filed: 1992-02-12
Granted: 2002-04-23
Abstract: In an apparatus for weighing continuously flowing flowable material, in which the mass flow is determined as a function of measurements of forces exerted on at least one plate (I) in contact with the flowing material, the main novel features are that the apparatus is adapted to perform at least two of said measurements in substantial dependence of the distribution of weight, such as between third points (A, B), on a basically rectilinear inclined plate, on which the material flows slidingly. With this ar-rangement, the results of the measurement may be used for creating an expression of the mass flow, the accuracy of which is inde-pendent of the flow velocity, density and friction of the material.

Abstract: A method is provided for drilling of a well bore portion including a short radius curved section followed by a straight section. A drilling tool is provided having a first portion on which the drill bit is mounted and a second portion carrying the motor with a knuckle coupling therebetween. The short radius curved section is completed using the drilling tool with the knuckle coupling diverting to one side of the bore to steer the drill bit to the other side. After the curved section is complete the drilling is controlled in an accuratelystraight orientation by providing an eccentric collar which is attached onto thedrilling tool at a position adjacent the knuckle portion. The eccentric collar holds the drilling tool at a slight angle less than that during the curved section. Simultaneously with the rotation of the drill bit, the drill string, the tool and the collar are rotated more slowly about the longitudinal axis so as to constantly vary the angle of attack of the drill bit. In one arrangement, prior to attachment of the eccentric collar, a cylindrical or concentric collar is attached for drilling of a first short section of the horizontal portion. In an alternative arrangement, the eccentric collar has two flat sides which allow the collar and tool to rotate in a slightly curved bore without binding.

Title: Method of testing pipes for leakage
Inventor: ASHWORTH ROGER PHILIP
IPC: G01M3/00
Filed: 1996-03-14
Granted: 2002-02-19
Abstract: Air is passed under pressure into a pipe under test and into a reference chamber connected to the pipe by a valve while recording at intervals of every few seconds the temperature in the reference chamber the temperature in the pipe and the absolute pressure in the reference chamber When the test pressure has been reached the valve is closed and the differential pressure between the pipe and the reference chamber is measured.  The valve is opened to equalise the pressure and then closed again and the differential pressure drift rate is measured.  This is repeated several times.  A computer is used to calculate a creep prediction curve.  A comparison is made to see whether the pressure drift rate due to creep and leak only in the pipe independent of any temperature change in the pipe is trending towards crossing the curve or not.
