Filed: 2001-12-20
Abstract: The invention relates to a method and device for reading postal codes of addresses on postal articles, in which the postal code (300) designates the address up to the portion of a major street or of a number of minor streets.  When addresses could not be clearly read during a first reading attempt (310 ) in the OCR unit (130), the postal code is first of all divided into a part that roughly depicts the address and into a part that depicts the address mo re precisely. The corresponding liknesses of the postal article surfaces to the se addresses are then transmitted to the video coding stations (200) where only  the parts of the postal codes (300) that roughly depict the addresses are video-coded (320) by operators provided therefor and are transmitted to additional video coding stations (200) where the remaining postal codes (300 ) that depict the addresses more precisely are asynchronously video-coded (330 ) by operators provided therefor. Afterwards, the buffered, video-coded postal  code parts, which respectively pertain to a particular postal article, are combined (340) to form a complete, video-coded postal code.

Inventor: CRISTOFALO MICHAEL G
IPC: H04N21/45
Filed: 2002-04-26
Abstract: A technique for optimizing the delivery of a multiplicity of advertisements and other programming (402) is providing by trading off full-motion video (404) for other forms of high quality still images, text, graphics and audio (406). By creating a group of synchronized digital programming components (408), for example, still-frame video, audio, graphics, text, animation, and media objects, which combined (416) utilize less bandwidth than a standard digital programming segment of full-motion video with CD quality audio, a greater number of differentiable programming content options can be made available in the digital transmission stream (418). Because of the greatly expanded amount of differentiable content that can be created using the bandwidth tradeoff techniques, greater precision in targeting particular content, such as advertisements, to particular users is possible. The invention also contemplates the system requirements, both hardware and software, for a digital programming transmission center and for user's receiver, necessary to implement the bandwidth tradeoff methodology.

Title: Method for operating and arrangement of a pneumatic piston engine
Inventor: FELDMAN JURI
IPC: F01B17/02
Filed: 2002-05-10
Abstract: The present invention concerns a method for operating and arrangement of a pneumatic piston engine. The pneumatic piston engine (1) includes a cylinder (2) including a piston (3) kinematically joined via a crank (4) to a crankshaft (5) and a working chamber (6) supplied with a means (7) for supply of compressed air and a means (8) for exhaust of air. The starting of supply of compressed air is realized while the piston (3) is in the region within the range from 40~ before top dead center to 25~ after top center by angle of rotation o the crank of the crankshaft depending on engine speed, and the ending of supply is realized while the piston (3) is in the region within the range from 0~ to 90~ after top dead center by angle of rotation of the crank of the crankshaft. In particular case when engine speed is 2.12 s-1, the optimum mode of operating is achieved provided that supply of compressed air starts when the piston (3) is in position of 2~ before the top dead center and ends when the piston (3) is in position of 5~ after the top dead center by angle of rotation of the crank of the crankshaft. The invention provides decrease of specific fuel consumption approximately by a factor of 5-6 and simultaneous increase of the piston specific power.

Inventor: NEUMAIER MICHAEL
IPC: C12Q1/68
Filed: 2002-06-28
Abstract: The invention relates to a method which allows to identify therapeutically useful compounds via the detection of the expression of glycoprotein antigens of the CEACAM family. The therapeutically useful compounds have properties that prevent the development of hyperplastic modifications that have been identified as precursors of a neoplastic transformation and that may lead to the formation of a carcinoma, or that reestablish a normalization of the tissue. The invention specifically relates to a method for identifying a compound/compounds that are useful in tumor prevention or for treating tumor precursors. The selected compounds are capable, by controlling gene expression, of increasing the apoptosis sensitivity of cells of the colon mucosa, especially of the precursor cells (or of reducing an apoptosis resistance). The invention further relates to a diagnostic method and to the use of the cells identified according to the invention in pharmaceutical compounds for preventing tumor formation and for treating the precursors thereof.

Title: System and method for the production of oil from low volume wells
Inventor: COLLETTE HERMAN D
IPC: E21B43/12
Filed: 2003-12-09
Abstract: An oil well pumping system includes a small positive displacement pump below the fluid interface in a low volume oil well which pumps at a rate to maintain approximately constant fluid level in the well. The system includes at least a pair of sensors in a sensor array that is positioned above the pump and near the fluid interface to unambiguously determine liquid level. By maintaining the pumping rate of the positive displacement pump below that required to lower the liquid level to the pump, the pump will not unload and pump power requirements are reduced to a nearly constant low rate. In addition, the pump off control function is accomplished by a microprocessor which is mounted adjacent to the downhole sensor array. This location allows simple direct control of the downhole electric motor and eliminates the requirement that a control element be placed on the surface far from the pump.

IPC: F23K5/14
Filed: 2004-01-09
Abstract: A control apparatus simultaneously controls flow rates of a first fluid and a second fluid. The apparatus comprises a control valve for controlling the flow rate of the first fluid and a bleed device for bleeding the second fluid. The control valve is operatively connected to the bleed device, whereby, as the control valve is opened progressively greater amounts to increase flow of the first fluid, the bleed device is progressively closed to decrease bleeding of the second fluid, and, as the control valve is closed progressively greater amounts to decrease flow of the first fluid, the bleed device is progressively opened to increase bleeding of the second fluid. The control apparatus may be installed in a burner unit of the type having a compressor supplying pressurized air to the burner and a fuel pump supplying fuel to the burner. The control valve controls the fuel and the bleed device increases bleeding of the air as the control valve closes.

Abstract: Embodiments of the present invention generally provide methods, apparatus, and systems for determining void fractions of individual phase components of a multiphase mixture. The void fractions may be determined based on measured parameters of the mixture as a whole, such as differential pressure, bulk velocity of the mixture and speed of sound in the mixture. According to some embodiments, the mixture parameters may be measured using non-intrusive fiber optic based sensors. Various other parameters may also be derived from the void fractions, such as individual phase flow rates, liquid holdup and watercut parameters (for oil and gas mixtures).

Filed: 2004-03-16
Abstract: A hybrid wellhead system its assembled using a plurality of threaded unions, such as spanner nuts or hammer unions, for securing respective tubular heads and a flanged connection for securing a flow control stack to a top of a tubing head spool. The tubing head spool is secured by a threaded union to an intermediate head spool. The intermediate head spool is secured by another threaded union to a wellhead. Each tubular head secures and suspends a tubular string in the well bore. The hybrid wellhead system is capable of withstanding higher fluid pressures than a conventional independent screwed wellhead, while providing a more economical alternative to a flanged, or ranged; wellhead system because it is less expensive to construct and faster to assemble.
