Title: Two-stage pressure regulator
Inventor: CARTER STEPHEN A
IPC: G05D16/06
Filed: 1994-08-30
Granted: 2005-06-07
Abstract: The present invention provides an improved two-stage pressure regulators for various compressed gases, and more particularly to pressure regulators used for gaseous fuels such as compressed or liquified natural gas. The pressure regulator of the present invention is a robust, compact, high flow, low droop, low pressure drop and low creep regulator which is suitable for both OEM and aftermarket use. It can be used by itself, or with an optional third stage to provide a three stage regulator such as the atmospheric (or zero pressure differential) types commonly used to regulate the fuel pressure for gaseous carburation systems. It is particularly useful in mono-, bi-, and dual fuel engine applications.     The two stage regulator of the present invention consists of a single base (the "regulator base") upon which are mounted all of the components of the regulator, including the first and second stage regulator spring towers, a pressure relief valve (or PRV) spring tower, a filter assembly, a high pressure solenoid-activated valve, and an optional cylinder pressure sender. Channels provided in the base, for example by machining, permit the flow of coolant or other fluid through the base to control the temperature of the pressure regulator, and thus the outlet temperature of the gas flowing through it.

Abstract: A log scanning system applies circumferentially spaced, traverse scans along the length of the log to provide a longitudinal density scan for each of the scans made. Each scan is made up of rows of density dependent pixels sensed by specific detector (scan line) and columns of density dependent pixels sensed by adjacent detectors arranged transversely of the log. The signals generated along each row are filtered to produce a clean signal scan line and each clean scan line is processed to determine positive peaks. The positive peaks are plotted to form an image and adjacent peaks in adjacent rows and columns are joined to provide a spine image depicting spines of detected knots in each scan. Knot shapes are then defined by reprocessing each scan along the rows or scan lines to determine the knot boundaries on each side of each of the spine lines based on pixels displaying a selected minimum density and these shapes applied to the spine image to provide a reconstructed scan. The longitudinal axis of the lo g is determined and applied to the reconstructed scans to define the roots or inner ends of the knots. The reconstructed scans are then used to define the same knot in each of the reconstructed scans and then to generate a three-dimensional image of the log which may then be used by a sawing progra m todetermine how the log should be sawed.

Title: Counterflow drum mixer for making asphaltic concrete and methods of operation
Inventor: BRASHEARS DAVID F
IPC: E01C19/10
Filed: 1994-10-20
Granted: 2004-12-28
Abstract: An inclined counterflow rotating drum mixer has a burner head intermediate an aggregate inlet at one end of the drum and an asphaltic concrete discharge at the opposite end of the drum. A fan supplies secondary air to the burner through a motive tube having an opening in communication with a mixing chamber between the burner head and the discharge end of the drum to aspirate gases from the mixing chamber for flow through the burner flame. The aspiration creates a negative pressure in the mixing chamber, causing a reverse flow of a portion of the combustion gases from the dryer chamber into the mixing chamber for preheating RAP input to the mixing chamber. RAP is also preheated by providing a preheat chamber adjacent the flame zone but segregated from direct contact with the flame to preheat the RAP. Hot and dried virgin aggregate is mixed with the RAP in the preheat chamber and valves are provided to prevent gases evolved from the RAP in the preheat chamber from flowing into the drying chamber.

Abstract: An imaging system wherein two field-of-views (FOVs) images of a scene are obtained and displayed as a single image so that both FOVs can be viewed simultaneously by an observer.          This imagining system is particularly directed to infrared (IR) imaging of a scene which is useful for search-and-rescue (SAR) operations.  One IR image sensor provides a low resolution, high sensitivity, wide field-of-view (WFOV) image of the scene which is displayed as a large, low resolution, WFOV image on a display apparatus.  A second IR sensor provides a high resolution narrow field-of-view (NFOV) image of a selected portion of the scene wherein the second sensor's NFOV optics can be directed to any particular area within the WFOV.  That smaller NFOV image is also displayed, by the display apparatus, within the WFOV displayed image and it is displayed at the same area in the WFOV image as that actually covered by the NFOV, the NFOV image displacing the WFOV image of that area with the two images being fused together into a single image by the display apparatus.          This is rather similar in operation to an observer's eye which has a high resolution central NFOV vision and a very large FOV peripheral vision that has low resolution but a high sensitivity to detection of any anomaly.  By using an eye movement tracking system to aim the NFOV image detector and the position that the NFOV image is displayed, an observer's central vision can always be directed to the high resolution NFOV image with that observer's peripheral vision simultaneously viewing the WFOV low resolution image.

Abstract: A method and system for retrieving and presenting or displaying digital images on a portion of an operator's workstation where another portion may be simultaneously displaying a conventional application. The image display system includes a mechanism for browsing images at a speed and in a direction through the ordered images chosen by the operator, much like an operator might browse through successive images on microfilm in prior art systems. The direction of image scrolling is operator selectable and the selections may be entered at a workstation keyboard or from another application, so the operator may move forward through the ordered archive of images until the operator finds a key document, then move backward and forward slowly until the images of the document answer the questions or it is determined that the images will not answer it. When a specific image is displayed, the operator can zoom in, magnify, look at the other views of the document, print the image or take other action as appropriate, using the present system.

Abstract: A microwave crosspoint blocking switch matrix and assembly (1) employing multilayer stripline and pin diode switching elements is employed to selectively electrically couple and decouple input transmission lines (2) to output transmission lines (4) without severance of the transmission lines and insertion of a series switch.  The microwave crosspoint blocking switch matrix assembly employs pin diode arrays (6) coupled to input and output transmission lines at respective crosspoints (8).  In order to route a signal from a specific input line to a selected output line, the pin diode array at the input/output transmission line crosspoint is activated and each transmission line is shorted at points one-quarter wavelength distant from the crosspoint to reflect, ideally, an infinite impedance at the interconnection point.  Therefore, a desired signal cannot propagate in any direction except from the selected input line to the desired output line.

Granted: 2000-01-25
Abstract: Fill and pressurization apparatus having a sectional fluid conductor (27) having a first section (27a) fixed relative to the surroundings, and a second section (27b) which moves toward the first section (27) to form an enclosure (Fig. 2) through which a high volume flow rate -low pressure flow may be passed to fill an adjacent open end of a tube (17) with liquid.  Said fluid is passed through an inlet conduit (38), which may be a rigid conduit, to the fixed first section (27a).  A seal head (77) insertable into the end of the filled tube (17) has an elastomeric seal member (87) and a rod (76) and a sleeve (78) relatively axially displaceable to compress the seal member (82) and deform it into sealing engagement with a surface of the tube (17).  A stop member (84) on one of the rod (76) and sleeve (78) and a stop surface (81a) on the other of the rod (76) and sleeve (78) limit the axial displacement and hence also the compressive force applied to the seal member (82).  The relative displacement is achieved by retracting one of the rod (76) and the sleeve (78) and blocking the retraction of the other.  The blocking is provided by two telescoping cylinders (89 and 96), one (96) of which has abutments (99) thereon running in channels (101) provided in the other cylinder (89).  To effect blocking one cylinder (96) is rotated relative to the other so that the abutments (99) are out of register with the channels (101) and engage stop surfaces (103) in an extended condition of the cylinders (89 and 96) relative to one another.

Title: Regulation of site-specific recombination by site-specific recombinase/nuclear receptor fusion proteins
Inventor: STEWART FRANCIS
IPC: C07K14/705
Filed: 1994-06-28
Granted: 2002-01-08
Abstract: An invention is described that permits the regulation of recombination in cells, organisms or appropriate cell-free systems. The invention involves creating fusion proteins between recombinase proteins, or components of recombinase systems, and ligand binding domains derived from nuclear receptors. The fusion proteins show little recombinase activity in the absence of the ligand that binds to the ligand binding domain. Upon binding of the ligand, recombinase activity is induced. The invention provides a practical means to regulate recobination in cells and organisms and, by linking ligand binding to recombination, provides a simple means whereby ligand binding can be measured as recombination achieved.

Abstract: An electronic control for a motor which eliminates the motor centrifugal switch and more particularly a control for a domestic refuse compactor which permits the user to control the approximate full trash bag weight and obtain more compaction from a split phase induction drive motor.  A ferrite core sensor on the main winding of the drive motor samples the lagging phase angle of the motor main winding current during a compaction stroke.  A low force cycle is achieved by terminating the stroke as soon as phase samples fall below a threshold defined at the start of each cycle by a locked motor main winding phase sample acquired prior to starting the motor.  A medium force cycle terminates the stroke when compaction forces exceed the main winding breakdown torque.  A high force cycle is achieved by reactivating a motor start winding when compaction forces exceed the main winding breakdown torque and terminating the stroke as soon as the phase samples exceed a threshold defined at the start of each cycle during motor starting.  The control uses programmed referencing techniques to eliminate factory precalibration.
