Title: Mesure et commande du debit de materiaux fluides
Inventor: WELCH BARRY JOHN
IPC: G01F1/78
Filed: 2000-03-24
Granted: 2007-05-15
Abstract: Cette invention concerne un procédé de détermination du débit d'entrée (Finlet) d'un matériau fluide. Ce procédé consiste: à faire passer un flux d'entrée de matériau fluide au travers d'une chambre (20) dotée d'une ouverture d'entrée (100); à mesurer un premier taux de changement quantitatif du matériau dans la chambre (20) lorsque ledit matériau pénètre selon le débit d'entrée susmentionné; à mesurer un second taux de changement quantitatif du matériau dans la chambre (20) lorsqu'aucun matériau ne pénètre dans ladite chambre; et à calculer le débit du flux d'entrée (Finlet) à partir des premier et second taux, les deux relevés de débit étant effectués lorsque l'ouverture d'entrée (100) de la chambre (20) est occupée dans sa totalité par le matériau fluide.

Abstract: This invention provides a system (190) and method for mapping parameters of a traffic congestion, for example, a road congestion, relative to a focus. Mapping of the road congestion may include determination of an average lengt h of the road congestion over a time interval, motion rate in the road congestion, and arrival rate to the road congestion. The mapping system (190 ) may construct snapshots of mapping samples received from a small percentage of probe vehicles (230) equipped with an appropriate receiver and transmitter. The mapping samples are preferably received in response to predefined broadcast queries sent by a central station (206). The determination of the average length of a road congestion may be based on a direct approach, obviating the need to estimate discrete lengths of the road congestion.</SDO AB>

Granted: 2006-04-11
Abstract: A track and trolley system that allows wall panels to be moved with a minimum amount of friction is disclosed. The track has first and second flanges vertically and horizontally spaced relative to each other. First and second discs are supported on a shaft in vertical spaced relation. One of the discs engages one of the flanges on one side of the shaft and the other disc engages the other flange on the other side of the shaft. Each disc is independently rotatable in opposite directions. The disc-supporting surface of the flanges includes a plurality of upwardly concave regions with each region formed with a different radius. The disc is sized so that the outer edge of the disc lower surface contacts the outermost upwardly concave region of the flange. The lower side of the discs is angled slightly upward from the outer edge toward the center. The combination of the contours of the disc lower surface and the disc-supporting flange surfaces result in a narrow contact area between the discs and flanges which minimizes friction between the discs and their respective flange as the wall panels are moved.

Title: Temperature compensation for straight tube coriolis flowmeter
Inventor: LANHAM GREGORY TREAT
IPC: G01F1/84
Filed: 2000-06-13
Granted: 2005-10-25
Abstract: Method and apparatus for providing compensation of mass flow rate and density for the flow tube of a single straight flow tube Coriolis flowmeter. Thermal stress compensation is provided by the use of a plurality of sensors on various portions of the flowmeter. A first sensor is coupled to the flow tube and provides information regarding the flow tube temperature. A plurality of additional sensors are connected to form a network having a two wire output.  The additional sensors apply a composite signal over the two wire output of the network to meter electronics. The network signal represents the composite temperature of the flowmeter elements that can cause thermal stress on the flow tube when a temperature differential exists between the flow tube and the temperature of these plurality of elements. The additional elements include the balance bar and the flowmeter case. Sensitivity compensation is provided by the use of a novel algorithm. Density is measured in a single tube flowmeter that is calibrated using two materials of different densities by the use of density equation that has non-linear components representing the deviation of the meter calibration from linear.

Abstract: Tissue clips (C) are placed on the upper level (47, 48) of bi-level product buckets (46), with the length of the tissue clips in the machine direction. The lower level (52) of the product bucket (46) is comprised of a full-width transverse channel (49) whose width is greater than the width of the tissue clips (C) but less the length of the tissue clips (C). To package flat packages of tissues (20), extensible pushers (14) turn the tissue clips (90) degrees so they drop into the transverse channels (49). Subsequently flat overhead tamps (85) descend and the tissue clips (20) are pushed through guide buckets (75) into the end of the flat-pack cartons (18). To package boutique packages of tissues, the extensible pushers (60, 62) are disengaged so the length of the tissue clips (12) remain in the machine direction spanning the transverse channels (49).  Subsequently, narrow tamps (86) descend, pushing the center of the tissue clips (12) into the transverse channels (49), forming the tissue clips (12) into the beginning of a U-shape ready for pushing through guide buckets (75) into the side of boutique cartons (10).  Methods and apparatus are disclosed.

Abstract: Resilient fibrous insulation batts are formed with the fibers of the batts being randomly oriented and entangled together and predominately lying in planes that extend substantially perpendicular to the major surfaces and the end surfaces of the batts and substantially parallel to the lateral surfaces of the batts to facilitate a widthwise compression of the batts. The batts are formed by collecting fibers into a blanket with the fibers being collected in layers lying in planes extending substantially parallel to the major surfaces of the blanket and the blanket having a thickness equal to the widths of the batts to be formed. The blanket is then cut longitudinally and transversely, in directions perpendicular to the major surfaces of the blanket, into sections having thicknesses and lengths equal to those of the batts to complete the formation of the batts.

Abstract: A jet spouted fluidised bed drier is described in which the bottom half of the drier chamber comprises a first lower conical part, and the top half of the drier chamber comprises a second upper conical part surrounding a conical grid located near to the top end of the second part. The drier chamber thus comprises two conical parts connected together at their wide ends. The result of this arrangement is that the collision zone becomes a toroid with an essentially triangular cross-sectional shape defined essentially by the conical internal surface of the top part and the conical outer surface of the conical grid. This revised structural arrangement has been found to be able to process materials which either cannot be processed, or cannot be processed efficiently, with known jet spouted fluidised bed driers. Additionally, this revised structural arrangement has been found to be able to process materials more efficiently, and to a lower desired final liquid content values.
