Abstract: A method and apparatus for creating multiple branch wells from a parent well is disclosed. According to a first embodiment of the invention a multiple branching sub is provided for placement at a branching node of a well. Such sub includes a branching chamber and a plurality of branching outlet members. The outlet members, during construction of the branching sub, have previously been distorted into oblong shapes so that all of the branching outlet members fit within an imaginary cylinder which is coaxial with and substantially the same radius as the branching chamber. According to one embodiment, the distorted outlet members are characterized by an outer convex shape. In another embodiment, the distorted outlet members are characterized by an outer concave shape when in a retracted state. After deployment of the branching sub via a parent casing in the well, a forming tool is lowered to the interior of the sub. The outlet members are extended outwardly by the forming tool and simultaneously formed into substantially round tubes.  Next, each outlet member is plugged with cement, after which each branch well is drilled through a respective outlet member. If desired, each branch may be lined with casing and sealed to a branching outlet by means of a casing hanger. A manifold placed in the branching chamber controls the production of each branch well to the parent well. According to a second embodiment of the invention, a pressure resistant branching sub is provided which may be installed in series with a casing string, and the associated equipment used for the installation operation and intervention of a well. The branching sub includes a main pipe and a lateral outlet.

Granted: 2005-01-04
Abstract: A low-power, multi-function cellular television system for transmitting signals at super high frequencies. Each cell transmitter radiates signals with one polarization over one sector, and signals with a different polarization over the balance of 360°. Sectors of adjoining cells are aligned to minimize interference from the adjoining cell. Adjoining cells may transmit different pluralities of carrier frequencies which are interleaved to minimize interference further, with each cell having one set of transmitted frequencies radiated for both polarizations, occupying at least 90 % of a band used in common for the system.

Abstract: A hybrid electric vehicle includes a lead-acid traction battery made up of a plurality of series-connected modules. During operation of the vehicle, the traction battery is discharged for acceleration, and charged by an ancillary power source. The traction battery is desirably not fully charged at the beginning of a day's operation, so that overcharging cannot occur, so the battery spends long periods of time in a partially charged condition. When not fully charged for long periods of time, sulfation may reduce the charge storage capacity of the battery. A maintenance procedure takes place when the vehicle is not operating, in which one or more modules of the traction battery, but less than all the modules, are fully charged, then partially discharged. The full charging tends to reduce sulfation in the particular module being maintained, and the partial discharge restores its charge condition to that prior to the full charge. Each of the modules is eventually maintained by a programmed controller. The charging energy comes from an auxiliary battery, and the discharge energy is returned to the auxiliary battery, so there is little net loss of energy. If the maintenance procedure is interrupted before full charge of a module, that module is scheduled for the next maintenance. If the maintenance is interrupted before partial discharge, the partial discharge is accomplished by equalizing the voltage of the battery modules.

Abstract: A plug-dropping head capable of dropping balls or plugs or other objects is disclosed. The plug-dropping head has a compact design with a cylinder having multiple chambers for storage of plugs and/or balls. The device can be actuated manually or automatically, locally or remotely, to rotate the cylinder to present a different bore in alignment with a flowpath through the housing. An exterior signal indicates that the object has fallen through the device. An indexing feature assures alignment of the individual bores in the cylinder which contain a plug or wiper with the main passage through the tool. Flow can be maintained through the tool as the cylinder is rotated. Rotation of the cylinder allows an obstruction device in the flowpath to move out of the way to allow the ball or plug to drop when sufficient alignment is reached.

Inventor: DENT PAUL WILKINSON
IPC: H04H20/00
Filed: 1998-01-28
Granted: 2008-11-18
Abstract: A method and apparatus for transmitting and receiving frequency hopped video signals is disclosed. A composite video signal (2) is processed at a transmission end to remove line and frame synchronisation codes (6, 8) and replace them with a frequency hopping synchronisation code (30). The signal (2) is then modulated with a frequency hopped carrier signal and transmitted to a receiver (170). The receiver detects the frequency hopping synchronisation code to enable tuning of the receiver to the video signal. The detected frequency hopping synchronization codes are removed and replaced with the original line and frame synchronization code. The recreated video signal may be digitized and processed to detect and correct errors within the video signal by replacing lines or frames of the video signal with closely related lines or frames from another portion of the video signal.

Title: High density column drivers for an active matrix display
Inventor: LEE DAVID D
IPC: G09G3/20
Filed: 1998-08-20
Granted: 2003-10-07
Abstract: To reduce the layout area required by LCD column drivers without suffering a significant decrease in performance, a PMOS-based circuit selects a voltage from an upper set of analog display voltages and a NMOS-based circuit selects a voltage from a lower set of analog display voltages. This reduces the layout area by up to roughly a factor of two compared with conventional column drivers which are CMOS-based. Moreover, in a typical dot inversion scheme, where two adjacent columns select voltages from alternating voltage sets, two adjacent columns can share the same PMOS-based and NMOS-based circuits by using multiplexers controlled by a polarity signal to route the digital display data into the sets of switches. This reduces the layout area by up to roughly an additional factor of two.
