Title: Apparatus for controlling the motion of a string of tubulars in a wellbore
Inventor: LUKE MICHAEL ANTHONY
IPC: E21B17/07
Filed: 1998-05-01
Granted: 2007-07-17
Abstract: This invention relates to an apparatus for controlling the motion of a string of tubulars in a wellbore. In milling a tubular with a downhole mill, using too much weight on the mill and/or advancing the mill too quickly can result in inadequate milling, inefficient milling, and damage to the mill, its associated equipment, and the item to be milled. In offshore milling operations, a mill lifted away from a tubular being milled, e.g.  by a swell at the water's surface that lifts a boat or barge from which the milling system is suspended, can be slammed back into the tubular being milled as the swell passes and the boat is effectively lowered. This is particularly undesirable.

Title: Punch down insulation displacement connector housing
Inventor: MILETTE LUC
IPC: H01R4/24
Filed: 1999-12-03
Granted: 2002-03-12
Abstract: A punch down insulation displacing connector housing is a body made of plast ic which surrounds the connector. The housing restrains the connector parts fro m longitudinal movement when the connector is positioned to be press fit onto or to be soldered onto a substrate such as a printed circuit board. The housing also aligns the openi ng of the connector with an opening slot on the body. Thus, the housing aligns a connection tool head used to insert a wire with the opening of the connector. This housing will stop movement of the connection tool head during wire insertion to position the wire inside t he connector at a desired position. Also, the housing offers a surface where the connection to ol head will stop and cut the wire. This housing is used on a compact electrical connector and  will surround the connector. The housing can accept various types of connection tool head.

Granted: 2002-09-17
Abstract: A system for controlling a speed of a vehicle having a continuously variable transmission (CVT) and a cruise controller which controls the traveling speed of the vehicle to a desired speed in response to the instruction to cruise control inputted by the vehicle operator. In the system, the detected throttle opening is smoothed or filtered such that the speed ratio of the continuously variable transmission is controlled based on the smoothed throttle opening and the detected vehicle speed when the instruction to cruise control is input. Alternatively, a parameter indicative of upslope of the road where the vehicle climbs is determined and the speed ratio is controlled based on the parameter and the detected vehicle speed. With this, the system can reduce the engine speed fluctuation and can prevent the vehicle operator from feeling uneasy when the cruise control is effected.

Abstract: The present invention is a biometric recognition method and system for identifying humans and animals with acoustic scanning techniques. The invention is based upon transmitting acoustic energy through an external accessible surface (14) to non-visible internal tissue (16) having unique distinguishing characteristic. A master representative pattern of the unique distinguishing characteristic is produced by the interaction of an acoustic energy beam with discontinuities and inhomogeneities within the non-visible internal tissue (16). The master representative pattern is used for reference and compared to a current representative pattern formed upon each attempted reentry into the system.

Abstract: A patient monitoring apparatus for monitoring a physiological characteristic of said patient. A user interface (70) having an interior portion (74) communicates with an airway of a user such that substantially all gas inhaled, and exhaled by the user enters the interior portion (74). At least one vent element (76) is associated with the user interface (70), and communicates the interior portion (74) of the user interface with an ambient atmosphere. The vent element (74), user interface (70) define a flow element across which a pressure differential is created during inhalation, and exhalation. The pressure differential is the pressure difference between the pressure within the interior portion (74) of the user interface (70), and the pressure of the ambient atmosphere outside the user interface (70). A sensor (78) communicates with the interior portion (74) of the user interface (70), measures a fluid characteristic resulting from this pressure differential, and outputs a first signal indicative of the measured fluid characteristic.

Granted: 2006-01-03
Abstract: An apparatus for electrospray ionization of a liquid sample matrix to prepar e the sample for introduction into a mass spectrometer. The inventive electrospray interface is arranged between a source of a liqui d sample matrix and an electrospray ionization needle. The interface includes a central chamber which contains elements for passively mixing the liquid sample flow with a modifying liquid added to the central chamber through a side channel. The side channel is isolated fro m the central chamber by a flow restrictor and the modifying liquid is provided to the side channel through a valve. A second valve, side channel, and flow restrictor are used to permit introduction of a calibration fluid into the central chamber through the first side channel. The inventive interface permits mixing of a modifying liquid with the liquid sample matrix to assist in nebulization of the liquid sample by reducing the surface tension of the sample containing fluid.

Abstract: A rotor (4) for an eccentric screw pump or a subsurface drilling motor consists of a straight, essentially cylindrical core element (21), onto which a shell (22) is forged by a cold-forging process. The forging gives the shell (22) the helical external form required for eccentric screw pumps (1). The rotor (4) described can be produced by non-cutting shaping, which is of considerable advantage in particular in the case of large rotor dimensions, since no waste material is produced.

Abstract: A control system is used in an intelligent power distribution network. The power distribution network includes multiple branches, each of which is connected to a power source, electrical devices connected to the branches, and a normally-open device connected between two or more branches. The control system includes control elements, each control elements being associated with an electrical device connected to a branch of the distribution network. The control system also includes a master control element associated with the normally-open device. The master control element communicates with the control elements and, when a fault occurs on the distribution network, prevents the normally-open device from closing when information from the control elements indicate that conditions potentially disruptive to the distribution network would occur if the normally-open device were closed. The master control element permits the normally-open device to close when information from the control elements indicate that conditions potentially disruptive to the distribution network would be avoided if the normally-open device were closed.
