Abstract: The stock approach piping to a multi-layered headbox can be modified to include a dilution water header that independently supplies dilution water, such as whitewater, to multiple CD segments or zones of the tube bank which supply stock to each layer. The CD basis weight profile of the final sheet is monitored and, in response to the measured CD profile, dilution water flow is increased or decreased to those tube bank segments that need their consistency altered. By selectively controlling the basis weight of distinct segments of the CD profile for each layer, a more uniform sheet can be produced.

Granted: 2004-04-20
Abstract: A header includes a generally C-shaped cutter bar supporting the sickle knife assembly across a front edge of the header. A draper assembly is carried behind the cutter bar and includes a pair of rollers at right angles to the beam carrying a continuous draper canvas band around the rollers with the front edge of the canvas underneath the cutter bar. The rollers and a support plate between the rollers for the upper run of the canvas are both recessed relative to the front edge of the canvas to leave a cantilever portion at the front edge of the canvas which projects under the cutter bar to forma seal. The position of the draper canvas on the rollers is guided by a pair of longitudinally extending ribs one adjacent but spaced rearwardly from the front edge and abutting the trailing edge of the cutter bar and the other adjacent but spaced forwardly from the rear edge and abutting a front edge of a rear plate. The ribs are formed integrally with transverse slats. The front rib forms a damming effect reducing the possibility of material sliding over the front edge of the draper. An upper surface of the front rib can be castelated to provide an increased aggressive action tending to pull the crop along the draper.

Title: System and method for location-based group services
Inventor: RAY DIPANKAR
IPC: H04W4/029
Filed: 1999-06-11
Granted: 2009-02-03
Abstract: A telecommunications system and method is disclosed for defining location-based group services, which can be implemented within a Group Call Services (GCS) node associated with a cellular network. When a group call is initiated, the GCS  can send a positioning request to a Mobile Location Center (MLC) to locate the group members within a specified area. The particular location can be defined by the group number or the location can be prompted by the GCS. For each group member, the position of a mobile terminal associated with that group member is determined and the call is set up only to those members which meet the specified area criteria. If none can be located within the specified area, the area can be expanded at the callers' request.

Title: Amortisseur pendulaire de vibration de vehicule/pont
Inventor: PATTEN WILLIAM N
IPC: B60G17/015
Filed: 1999-08-12
Granted: 2006-06-13
Abstract: On décrit un amortisseur pendulaire de vibration destiné à atténuer les vibrations d'un pont sur lequel se déplace une véhicule. Cet amortisseur pendulaire de vibration inclut plusieurs ensembles actionneurs réglables présentant une première et une deuxième chambres à fluide reliées par une soupape. Les ensembles actionneurs sont reliés au véhicule et des capteurs de mouvement sont fixés au véhicule pour mesurer les vibrations du véhicule. Un organe de commande réagit aux données de mouvement et émet un signal de commande de la soupape régulant le débit du fluide entre la première et la deuxième chambres. Ainsi, la quantité d'énergie de vibration dissipée par l'amortisseur pendulaire de vibration est sélectivement variée, si bien que la rigidité des ensembles actionneurs réglables et le niveau d'atténuation des vibrations sont réglés en permanence pour empêcher un couplage résonnant entre le véhicule et le pont sur lequel celui-ci se déplace.

Abstract: An apparatus for providing a two-dimensional image of a three-dimensional object (1) illuminates the surface (11) of the object using an illumination source (2). Portions (6) of the surface are imaged through an aperture (12) in a plate (5) onto a portion (7) of a matrix sensor (3). The object is rotated about its principle axis while being simultaneously translated, and, at the same time the aperture is also rotated. By synchronising these translational and rotational movements, successive portions of the object surface can image onto respective successive portions of the matrix sensor, thereby providing an improved two-dimensional image of the surface of the object.

Granted: 2009-12-22
Abstract: A method is provided for more efficiently transmitting data from a server computer to a client computer over a communications network, the nodes of which are capable of providing two classes of transmission quality. Data is transmitted using the high priority class until a local cache at the client computer is filled to a certain upper threshold, at which point the data is transmitted using the low priority class. If the local cache at the client computer subsequently reaches a lowe r threshold then the transmitted reverts to the use of the high priority class. The communications network may be connection-based (e.g. ATM ) or connection-less (e.g. the Internet).

Title: Variable firing rate fuel burner
Inventor: HALLIT RAYMOND I
IPC: F23D14/66
Filed: 2001-10-11
Granted: 2006-08-01
Abstract: A variable firing rate fuel burner has a tubular body configuration defined by a central pilot tube coaxially circumscribed by intermediate and outer firing tubes. A pilot fuel-air mixture is flowed through the pilot tube and ignited to maintain a pilot flame at the open outlet end of the burner body. During firing of the burner, separate fuel-air mixtures are flowed through an intermediate annulus between the intermediate firing tube and the pilot tube, and an outer annulus between the intermediate firing tube and the outer firing tube. As these fuel-air mixtures exit the burner body they are ignited by the pilot flame, with the fuel-air mixture exiting the outer annulus serving as a flame shaping mechanism to provide the overall burner flame with a controlled, elongated shape. By using two separate fuel-air mixture flows surrounding the pilot fuel-air mixture flow, the firing rate of the burner may be easily modulated, and the burner may be simultaneously operated with two different types of fuel.

Inventor: MATSUI KAZUHIRO
IPC: F23R3/34
Filed: 2002-03-22
Granted: 2007-12-11
Abstract: This pilot nozzle has a fuel oil supply pipe disposed at the center of a heat-shielding air layer that is provided along an axial core, and a plurality of atomizing-fluid supply paths are disposed in the circumferential direction of a cylinder unit that surrounds the outside of the heat-shielding air layer. The atomizing-fluid supply paths and the fuel gas supply paths are disposed alternately and uniformly.
