Title: Pet nail cover
Inventor: KUZUU MASAYUKI
IPC: A01K13/00
Filed: 2003-05-22
Abstract: A pet nail cover has a sack portion that is shaped and dimensioned so as to cover at least the main toe and nail of the animal and extends into a groove between the toe's small flesh pad and a large flesh pad on the bottom of the animal's foot, thereby leaving the large flesh pad exposed, allowing for the animal's traction, mobility and comfort.

Title: Beam winding apparatus
Inventor: HARTMAN DAVID P
IPC: D02H5/00
Filed: 2003-05-28
Abstract: An apparatus and method for winding a sheet of aligned parallel yarns onto a beam is described. The beam winder utilizes a circularly arced yarn spool rack that feeds each yarn to an alignment comb through associated guide tubes. The distance between each spool of yarn and the alignment comb is substantially the same for all spools of yarn, thereby equalizing the force necessary to pull them to the comb. Next, the aligned sheet of material is preshrunk using heated rollers and wound onto a beam. Multiple speed controlled stepper motors are utilized to maintain a constant low level of tension in the sheet during the shrinking process. After shrinkage, the tension level of the yarn sheet is increased as it is wrapped onto the beam. A  turntable that supports two or more beams is provided to facilitate the rapid switching of beams once one beam has become full.

Title: Hydrodynamic rotary seal with opposed tapering seal lips
Inventor: KALSI MANMOHAN S
IPC: F16J15/32
Filed: 2002-04-05
Abstract: A hydrodynamically lubricating rotary seal for partitioning a lubricant from an environment has a generally circular seal body (104) and sloping, generally opposed projecting static and dynamic sealing lips (128 and 127). The dynamic sealing lip (127) is provided for establishing compressed sealing relation with a relatively rotatable surface, and has a sloping dynamic sealing surface (140) that varies in width, and also has a hydrodynamic inlet curvature (142) that varies in position around the circumference of the seal. The seal is installed against a relatively rotatable surface (115), the dynamic sealing lip deforms to define a variable width interfacial contact footprint against the relatively rotatable surface that is wavy on the lubricant side, and wedges a film of lubricating fluid into the interface in response to relative rotation. The environment edge of the interfacial contact footprint is substantially circular, and therefore does not produce a hydrodynamic wedging action in response to relative rotation.

Plusieurs utilisateurs peuvent être assignés à chaque faisceau au moyen d'un multiplexage en fréquence ou d'un multiplexage orthogonal et les données d'utilisateur peuvent être codées en faisceaux au moyen d'un codage par déplacement de fréquence ou d'un codage par déplacement de phase. Pour chaque technique de codage, les signaux de commande d'antenne codés sont combinés en un signal de commande de gain total et de déplacement de phase total, qui pilote un seul dispositif de commande de phase et de gain pour chaque élément d'antenne. En outre, un seul modulateur de données génère les paramètres de codage pour tout le système de communication.
