Title: Corrosivity measurement device with temperature compensation
Inventor: TIEFNIG EUGEN
IPC: G01N17/00
Filed: 2003-04-25
Granted: 2012-07-10
Abstract: An improved corrosion measurement system for determining the rate of corrosion of a fluid medium. The system is comprised of a highly sensitive excitation and amplification electronic circuitry for registering and displaying the stable and accurate measurement results. A novel current feedback amplifier maintains a constant alternating current voltage across the reference element, by simultaneously controlling the current through the serially connected reference and corroding elements, thereby keeping the corrosivity measurement independent of the probe's ambient temperature. The unique unitized electrical resistance measurement probe is also temperature stabilized using thermally bridged and balanced metallic elements; the first reference element being coated with an impermeable insulating coating, the second, the sacrificial corroding element, being fully exposed to the corrosive fluid medium.

Abstract: Selon la présente invention, dans des puits de forage fortement déviés (2) ou lorsque l'angle d'inclinaison relatif entre la stratification du terrain (4) et l'axe du puits de forage est grand, les mesures d'induction de rangée présentent des pointes erratiques, des séparations de courbes trompeuses, et des valeurs de résistivité imprécises, empêchant les diagraphistes (Fig. 3) d'évaluer précisément les résistivités d'invasion et de formation. Pour résoudre ces problèmes, divers procédés de correction et diverses techniques d'inversion ont été développés. Cependant, les procédés de correction, permettent seulement d'obtenir des résultats satisfaisants lorsque l'angle d'inclinaison relatif (205) est faible à modéré, et les techniques d'inversion sont généralement très chronophages.

Abstract: A device (1) for bending an extremity (3) of a torsional spring (5). The device includes a base plate (7); at least one flange (9) projecting from the base plate; at least one bulge (11) projecting from the at least one flange; a lever arm (13) pivotally mounted onto the at least one flange about a first pivot axis; and at least one cam pivotally mounted onto the lever arm about a second pivot axis. The lever arm is operable between first and second positions and each cam (15) has a contact surface (21) being positioned for operatively cooperating with a corresponding bulge. Prior to the bending operation, the extremity of the torsional spring is inserted between a given bulge and the contact surface (21) of a corresponding cam when the lever arm is in the first position. In operation, the extremity of the spring is bent about the given bulge by the contact surface of the corresponding cam when the contact surface is urged towards the bulge and forced about the same over the extremity of the spring as the lever arm is operated into the second position. The device enables an easier, simpler and more cost effective way of bending an extremity of a torsional spring, without the use of heat for bending the spring tail, and may be easily transportable from one site to another. Moreover, the device can be used for bending the extremities of torsional springs having different wire sizes.

Abstract: L'invention concerne un procédé destiné à localiser un défaut dans une section d'une ligne de transmission au moyen de mesures de courant de tension et d'angles entre les phases au niveau d'une première (A) et une seconde (B) extrémité de cette section. L'invention est caractérisée en ce qu'elle comprend les étapes consistant à calculer, après la survenue d'un défaut le long d'une section, une distance (d<SB>A</SB>, d<SB>B</SB>) jusqu'à un défaut en fonction d'un courant de défaut mesuré au niveau d'une des première et seconde extrémités et des tensions de phase mesurées au niveau à la fois de la première et de la seconde extrémité (A, B), la distance de défaut étant calculée à partir de l'extrémité (A ou B) où le courant de défaut est mesuré. L'invention est particulièrement utile lorsqu'un transformateur de courant d'une des extrémités (A, B) est saturé. Si tel est le cas, une distance (d) jusqu'au défaut est calculée en fonction d'un courant de défaut mesuré au niveau de l'extrémité non affectée et des tensions de phase mesurées au niveau de l'extrémité affectée et de l'extrémité non affectée.

Abstract: An anchor assembly for supporting a post and a base plate for the assembly. The assembly includes a tubular anchor body with an arcuate interior area. The anchor body is configured to receive a post having an arcuate exterior profile and a hollow lower end. The base plate is for connection with the anchor body.

The base plate has an arcuate conical portion that has a cross-sectional area that is complementary to the hollow lower end of the post and that has a greatest radial dimension at a base of the conical portion. The greatest radial dimension is greater than a complementary dimension of an interior surface of the post to cause the interior surface to slide over the conical portion and the conical portion to frictionally engage the post to prevent lateral movement of the post.

Abstract: A fail-safe fluid transfer control apparatus has full redundancy in the response to various inputs such as overfill probe signals, ground detection signals, and the like.   Independent microprocessor controllers independently evaluate the inputs and each output control signals to close a respective relay when the inputs indicate that fluid transfer may commence. The relays are arranged in series such that both must be closed for a fluid transfer to commence. The control signals from each controller include a static signal and an alternating signal, both of which must be properly output to close its respective relay.   Each controller monitors the state of each relay, and discontinues its control signals if either relay appears to be malfunctioning. Each controller runs an different, independently written firmware program to process the detected inputs to prevent a common firmware error. An optical bypass key replaces conventional mechanical keys and transmits an optically encoded signal to the controller for establishing a bypass condition. A preheating circuit is also provided for providing a dynamic voltage supply to standard thermistor probes which may be encountered.
