Title: Water jet slitter with laser finish and method
Inventor: GANGEMI DONALD C
IPC: B26F3/00
Filed: 1991-08-22
Granted: 1996-06-11
Abstract: A high pressure water jet (32) is used in conjunction with a relatively low power laser (34) to produce a smooth cut (C) in a traveling web (W). The cutting procedures produces a relatively small amount of fiber dust in the atmosphere surrounding the cut-ting operation. The water jet (32) severs the traveling web (W) into separate parts (Ws, Ws'), and the laser (34) is directed to the severed edges (E, E') to burn away the protruding ends of the paper fibers to produce a uniform, smooth cut (C) in both severed edges. A trough (18) is disposed on the side of the web opposite the water jet (32) and laser (34) to receive and collect the water severing the web and the fiber dust, and to diffuse the laser beam emissions.

Title: Distributed switching in bidirectional multiplex section-switched ring transmission systems
Inventor: MARRA WILLIAM C
IPC: H04Q11/04
Filed: 1993-04-22
Granted: 1999-06-15
Abstract: Long delays in bidirectional multiplex section-switched self-healing ring transmission systems are avoided by eliminating looping of communications signals when restoring them in response to a failure in the ring and by distributing switching of paths to be protected to ring nodes other than those immediately adjacent the failure. This is realized by provisioning each node in the bidirectional multiplex section-switched ring transmission system with a map of its traffic pattern (all active tributaries) and the relative position of each ring node in the ringtransmission system, and allowing the ring node, if it has communications traffic affected by the failure, to bridge and switch to and from the protection path.

Title: Debitmetre-masse a effet de coriolis
Inventor: KALOTAY PAUL ZOLTAN
IPC: G01F1/84
Filed: 1992-07-30
Granted: 1999-05-18
Abstract: Débitmètre massique à effet de Coriolis servant à mesurer le débit massique d'un matériau dans un conduit. Le débimètre présenté peut être monté directement sur un tuyau existant ou un autre conduit sans que l'on ait à dévier le flux de matériau. Le débitmètre comprend un mécanisme (20) tel qu'un dispositif d'attaque magnétostrictif, servant à faire osciller une section du tuyau entre deux support (12, 14). Le dispositif (20) est monté sur un ventre d'ondes ou près d'un ventre d'ondes du second mode d'harmoniques de la fréquence naturelle de la section du tuyau. Un capteur (30) monté à côté dudit dispositif d'attaque est actionné par l'intermédiaire d'un circuit de commande (Fig. 5) pour commander la fréquence d'oscillation de la section du tuyau. Un deuxième capteur (32), tel qu'un accéléromètre, est monté au niveau du noeud du second mode d'harmoniques de la fréquence naturelle de la section du tuyau au moment où le débit est égal à zéro (noeud de débit zéro). Le deuxième capteur mesure l'amplitude du déplacement du noeud de débit zéro due aux forces de l'effet de Coriolis résultant de la masse de matériau s'écoulant à travers le tuyau oscillant. Cette mesure donne une indication du débit massique du matériau s'écoulant à travers le tuyau. Le débitmètre est indépendant de la détection de décalage de phase et il n'est pas sensible au bruit étranger. Ce débitmètre ne nécessite pas en outre un montage compliqué. Dans d'autres modes de réalisation, le débitmètre est préfabriqué sur une section de tuyau qui peut ensuite être installée dans une tuyauterie et constituer un article disponible sur stock. ur image.

Title: Anti-decubitus mattress pad
Inventor: DINSMOOR JOHN C III
IPC: A61G7/057
Filed: 1992-08-28
Granted: 1998-09-01
Abstract: A mattress pad (1) is multi-layered and includes a cover or casing (5, 7) containing interior strata of a plastic film (17) layer atop a fluid bladder layer (19) supported on an underlying layer of foam (21). The reduction of the lateral shearing forces on a user of the pad is accomplished by oversizing the plastic film layer (17) and fluid bladder layer (19) on the underlying layer of foam (21) and by positioning microbeads between the plastic film layer (17) and fluid bladder (19) layer to dramatically reduce the friction drag or lateral shearing forces between the layers.  Normal pressures and forces are reduced by oversizing, modifying the configuration, filling, and size of the discrete fluid pouches (41, 41', 41") of the fluid bladder layer (19), and varying the spring characteristics of the support columns (49) in the underlying foam layer (19) by hollowing them out to different degrees (53, 53'), adjusting their spacing, selectively tying adjacent columns (49) together.

Title: Method and apparatus for extracting features of moving objects
Inventor: KATO KOICHI
IPC: H04N7/00
Filed: 1994-09-02
Granted: 2000-04-04
Abstract: The present invention is intended to reconstruct or acquire the shape of an object without rotating it.  A TV camera 15 with a fish-eye lens 16 is used to conduct the image-sensing of a vehicle 12 as a moving object over a certain section of its path of travel and a background image is subtracted from each captured image to obtain a silhouette of the vehicle.  The loci of movement of vehicle's tires in each image are calculated and used to calculate the positions of the viewpoint of the TV camera and the vehicle relative to each other in each image.  The shape of the vehicle is reconstructed by projecting the silhouette for each captured image into a projection space while holding the viewpoint of the TV camera and the vehicle at the calculated relative positions.

Title: Coated polymeric fabric having durable wettability and reduced adsorption of protein
Inventor: QUINCY ROGER BRADSHAW III
IPC: A61F13/20
Filed: 1994-05-02
Granted: 2006-07-18
Abstract: A method of durably rendering a polymeric fabric, e.g., a polyolefin fabric, wettable and resistant to protein adsorption. The method involves providing a polymeric fabric having a surface, applying to the surface of the polymeric fabric a composition which includes water and a surfactant adapted to durably render the polymeric fabric resistant to protein adsorption, and drying the polymeric fabric. The surfactant has a solubility in water at 20°C no greater than about 5 percent by weight, based on the weight of the water, and is present on the polymeric fabric in an amount of the surfactant sufficient to reduce the adsorption of the protein by the fabric. The coated fabric not only exhibits durable reduced adsorption of protein but also has durable wettability by aqueous liquids. The coated fabric is especially suited for incorporation in such disposable absorbent articles as diapers, feminine care products, such as sanitary napkins and tampons, incontinent care products, training pants, wipes, and the like.

Abstract: A method for locating underground cylindrically symmetrical magnetic sources, particularly boreholes, from magnetic field measurements. The method is based on the shape of magnetic field produced by magnetic materials with cylindrical axes. As the field caused by the magnetic source always points away from or towards its cylindrical axis, lines extended from magnetic field vectors caused by the magnetic source will always pass through the axis. Numerical techniques are used to find the common line to all the extended magnetic field vectors and thus calculate the axis of the magnetic source.

Abstract: Data communications apparatus and methods employing a bidirectional lowbandwidth channel and a unidirectional high bandwidth channel. A PC is coupled to an information source by a communications system which provides both a bidirectional low bandwidth channel between the PC and the information source and a high bandwidth channel in which the information source is the source and the PC is the sink. A component of the communications system termed the director responds to a message received in the low bandwidth channel by switching the information being sent from the information source to the PC to the high or low bandwidth channel as specified in the message. The message may come either from the PC or the information source. A graphical user interface at the PC provides the user with "buttons" to specify the bandwidth. The apparatus and methods may be advantageously employed to provide telecommuting services.
