7789026, Sep 7, 2010

Filed:

Jan 3, 2003

Appl. No.:

10/336112

Inventors:

John E. Traina - Pittsburgh PA, US

International Classification:

F23B 7/00

US Classification:

110341, 110234

Abstract:

In a power generation system biomaterial is grown in a biomass field near a furnace. The plants or oils from the plants are periodically harvested and burned by the furnace to generate steam which runs a generator. Waste heat from the furnace and condenser is collected and returned to the biomass field. The by-products of combustion, principally heat, carbon dioxide, water vapor and ash, are in part cycled back to a biomass field as input energy and nutrients.

Inventors:

John E. Traina - Pittsburgh PA, US

International Classification:

B60L 1/02

US Classification:

219205

Abstract:

A method improving fuel economy by the retention of heat in or heating a liquid cooled, internal combustion engine is provided wherein insulation, a heating member, or both are attached to the engine and used to reduce heat loss from the engine or keep the engine at an operating temperature. The engine is subsequently maintained at the operating temperature or a temperature substantially close thereto for either a period of time determined by a user or for a time period that is longer than time periods obtained by following standard practices.

International Classification:

G01F 146

US Classification:

73861065

Abstract:

A method of measuring fluid flow through a conduit first finds a null position then rotates the probe 90. degree. from the null position to be aligned with the true flow direction of the field. The null position is found by incremental movement of the probe through selected angles. At each position a differential pressure reading is taken. These readings are then compared to determine subsequent incremental movements to identify an approximate null position. The true null position is found from the approximate null by applying at least squares fit to differential pressure readings taken within a range, preferably +/-5. degree. , around the approximate null. The probe is then rotated 90. degree. from the null position. A plurality of differential pressure readings are taken and the square root of each such reading is found.

US Classification:

250575

Abstract:

An improved transmissometer of the type which has a visible light source and is responsive to peak and mean spectral responses between 500 nm and 600 nm and optical assembly therefor contains a solid state light source preferably a light emitting diode. The light source emits a low level light beam that is split, part of which is passed through a gaseous sample then directed to a detector while the other part is directed to a second detector. Electronic components are provided to amplify the signal that has passed through the sample providing high gain, low noise amplification and use signals from the detectors to control the light source and determine opacity of the sample.

United Sciences, Inc. - Gibsonia PA

International Classification:

G01N 124

US Classification:

7386434

Abstract:

A gas sampling system utilizing a pair of parallel sonic orifices. One of the orifices is connected to a source of filtered, heated samples. The second, larger orifice is connected to a source of dilution gas. A vacuum pump maintains a substantial vacuum behind the orifices, thus assuring critical flow therethrough. The sample and diffusion gas are mixed behind the orifices and transported under partial vacuum for analysis. The dew point of the sample is affected by both the ratio of the diameter of orifices and the degree of vacuum transporting the gas mixture. As such, the dew point can be varied indefinitely by any reasonable combination of orifice ratio and vacuum pump strength.

International Classification:

G01N 3106
G01N 2556
G01N 700

US Classification:

73 2501

Abstract:

A gas concentration monitor has a pneumatic bridge having two parallel flowpaths containing a first conduit leg and a second conduit leg connected to an input line. Each leg has an entry orifice and an exit orifice through which a portion of the gas sample flows. Orifices need not be of equal size and or kept at the same temperature. A pump is connected to both legs for drawing the sample through the bridge. A condenser or absorber which removes the gas whose concentration is being determined is connected to the first leg between the entry orifice and the exit orifice. A differential pressure gauge measures the differential pressure between the first leg and the second leg which differential pressure changes due to removal of the target gas of measurement interest from the other gas fraction passing through the bridge towards discharge from the bridge. From that measurement one can calculate the concentration in the sample of the gas that was removed by the condenser or absorber.

Assignee:

United Sciences, Inc. - Gibsonia PA

International Classification:

G01F 146

US Classification:

7386167

Abstract:

A probe for measuring fluid velocity through a conduit has a pitot tube connected to a multiple channel cylindrical tube which is placed within a tubular housing. Drive motors are provided to permit precise rotation and longitudinal movement of the cylindrical tube and attached pitot tube in the conduit, typically a stack or duct. At least one differential pressure gauge is connected to the cylindrical. A computer directs movement of the cylindrical tube, receives differential pressure and static pressure readings from the differential pressure gauge and utilizes that data to calculate flow of the fluid through the conduit. The device is particularly useful for measuring stack gas flow which flow can be utilized to determine emissions of pollutants.

International Classification:

G01F 146

US Classification:

7386165

Abstract:

A improved Type S or reverse type pitot tube has two conduit legs which are mirror images of one another. Each conduit leg has an input portion having a pressure port therein, a support portion and a connecting portion connected between the input portion and the support portion. The support portion and the connecting portion lie in one plane which plane is substantially perpendicular to a centerline through the input portions. The conduit legs are shaped and oriented relative to one another so that the pressure ports of the input portions of the first and second conduits are collinear and when placed in a conduit, the pitot tube will be symmetrical in a yaw plane and both symmetrical and non-interfering in a pitch plane. The first and second conduits are spaced apart over at least a portion of their length to define an opening adjacent the input portions which opening is at least 3 times wider and deeper than the input portions. With this pitot tube the errors in flow measurement which result from the pitch angle flow are negligible in most cases and never result in a low biased reading.
