Title: High resistance grounding systems for oil well electrical systems
Inventor: JAESCHKE JAMES R
IPC: E21B47/12
Filed: 1999-08-06
Granted: 2010-05-25
Abstract: In accordance with the invention, a normally ungrounded power system for a oil well is provided which includes power transformer above ground and a pump motor below ground. There is provided a signal system which includes a below ground sensor system and an above ground signal conditioning and monitoring unit where the sensor system utilizes the main power lines for carrying the sensor signals. A connectable high resistance grounding scheme is provided to the aforementioned floating system, so that in the event of a arcing ground fault or similar occurrence the system may be immediately grounded, thus compensating for the effects of the arcing ground fault and providing personnel safety and electrical equipment protection. When the high resistance grounding system is not utilized the aforementioned signals from the sensors are easily carried by the power conductors.

Abstract: The disclosure relates to a positioning apparatus for workpieces whose length is to be adjusted. The apparatus includes a conveyor which advances the workpieces. Beside this feed conveyor, there is an additional conveyor on which adjustable abutment means are mounted. The two conveyors move at the same speed and in the same direction, so that each one of the abutment means, throughout the entire movement, is located in register with one and the same workpiece. A  transverse displacement device realises the lateral displacement of the workpieces until such time as the abutment means receive them. The abutment means may be either stepwise or continuoulsy adjustable. For a further stabilisation of the workpieces, there is a rail mounted at the discharge end of the conveyor, so that the end of each workpiece will slide along this rail without being displaced in the transverse direction.

Abstract: An exhaust brake control system for a vehicle drive train having an internal combustion engine with an exhaust system includes an exhaust brake valve in the exhaust system. Further, a controller controls the exhaust brake valve through a number of position commands from fully open to fully closed. Inputs to the controller affecting its operation include a speed sensor, a drive coupling sensor, a gear selection sensor, an overdrive gear sensor, an engine speed sensor, a throttle sensor, a pressure sensor and a warm-up sensor. A user interface both receives and sends information from and to the controller. The exhaust brake control system not only includes modulation of the exhaust brake, but also provides for control of a torque converter clutch, automatic transmission and overdrive. With throttled engines the intake throttle valve can be opened and the fuel supply disabled. Modulation of the exhaust brake valve is responsive to speed and acceleration.

Title: Light separation and recombination system for an off-axis projector
Inventor: SCOTT BRADLEY A
IPC: H04N9/31
Filed: 1998-10-13
Granted: 2007-05-01
Abstract: A color separation and recombination system separates a beam of white light traveling along an optical axis into three differently colored light beams. The system then independently modulates each colored beam and recombines the colored beams to create a color image. The system includes a crossed pair of dichroic filters to separate the beam of white light and to recombine the modulated bundles. The system also includes a pair of aberration-compensating elements that equalize the optical thickness of glass through which each light bundle passes. This equalization of optical thickness equalizes the aberration induced into each bundle. In another embodiment the beam of white light is polarized before separation. The polarities of the colored light beams are then modulated using a spatial light modulator. An analyzer and half-wave plate are provided between the spatial light modulator and the crossed dichroic filters to pass only a portion of the modulated light. The half-wave plate ensures that the modulated light incident on the crossed dichroic filters is of the same polarity as was the polarized white light separated by the crossed dichroic filters.

Abstract: L'invention concerne un dispositif de détection de vapeur suffisamment petit et léger pour être tenu à la main, ce dispositif étant également modulaire pour lui permettre de s'adapter en cours d'utilisation afin de détecter la présence et la concentration de différents types de vapeurs. A ces fins, ce dispositif est pourvu d'un module de détection auquel est intégré une chambre de prélèvement et plusieurs détecteurs, placés sur une puce reposant de manière amovible sur cette chambre, ou à proximité de celle-ci. Eventuellement, ce module de détection peut être configuré de manière à être branché de manière amovible dans un réceptacle, ménagé à l'intérieur du dispositif. Les vapeurs sont amenées à traverser ladite chambre de prélèvement, les détecteurs produisant un ensemble distinct de signaux électriques en réponse à chacune de ces vapeurs. Les détecteurs de ce module de détection peuvent se présenter sous la forme de résistances chimiquement sensibles, dont la résistance varie en fonction de la nature et de la concentration d'une vapeur adjacente. Ces résistances chimiquement sensibles peuvent être montées en série avec une résistance de référence, entre une tension de référence et une mise à la terre, de sorte qu'un signal analogique est établi pour chacune de ces résistances chimiquement sensibles. Les signaux analogiques ainsi obtenus sont ensuite transmis à un convertisseur analogique-numérique, de manière à produire les signaux numériques correspondants, lesquels sont analysés afin d'identifier le type de vapeur.
