Granted: 2001-06-05
Abstract: A pneumatic tire has an integrated circuit transponder which, upon interrogation by an external RF signal, transmits tire identification and tire pressure data in digitally-coded form. The transponder has an antenna adjacent and thereby coupled by electric or magnetic fields to an annular tensile member comprising a bead of the tire. The antenna has lead wires that preferably are positioned between the innerliner of the tire and its continuous carcass ply. The transponder thus is on the axially inner side of the reinforced carcass ply. A pressure transducer is within the transponder and is responsive, preferably through the innerliner material, to pressure within the tire. If the antenna is a coil, the coil is substantially planar in shape and parallel with the reinforced carcass ply.      The transponder and pressure transducer also can be attached to the axially inner side of the innerliner.

Granted: 1995-07-25
Abstract: In a headbox (10) of a web forming apparatus (12), a trailing element device (14) is disclosed for dividing a flow of stock (16) flowing through a slice chamber (18) of the headbox (10) towards a slice lip (20) of the headbox (10). The trailing element device (14) includes a rectangular sheet (22) having an upstream and a downstream end (24, 26) and a first and a second surface (28, 30). The upstream end (24) of the sheet (22) is pivotally secured within the slice chamber (18) for dividing the flow of stock into a first and a second current (34, 36). The downstream end (26) of the sheet (22) freely floats adjacent to the slice lip (20) such that the first current of stock (34) flows past the first surface (28) and the second current of stock (36) flows past the second sur-face (30) so that turbulence within the slice chamber (18) is reduced. At least one of the surfaces defines a plurality of parallel-spaced grooves (42-45 and 46-49) extending in a direction from the upstream to the downstream end (24, 26) of the sheet (22) for inhibiting the formation of machine direction vortices within the flow of stock that would otherwise cause streaking of the result-ant web (W).

Title: Distributed management communications network
Inventor: HERVATIC ELIZABETH ANNE
IPC: H04L12/56
Filed: 1993-04-20
Granted: 1998-05-05
Abstract: A multinode,  multicast communications network has  a distributed control  for the  creation,  administration and operational mode selection operative in each of the nodes of the network. Each node is provided with a Set Manager for controlling either creation of, administration or access to a set of users to whom a multicast is to be directed.  The Set Manager maintains a record of the local membership of all users associated with the node in which the Set Manager resides.   A given Set Manager for each designated set of users  is  assigned the  task  of being the  Set Leader  to maintain membership  information  about  the  entire  set  of users in the multicast group.  One of the Set Managers in the communications network is designated to be the Registrar which maintains  a  list  of  all  the  Set  Leaders  in  the network.  The Registrar insures that there is one and only one Set Leader for each set of users,  answers inquiries about the membership of the sets and directs inquiries to appropriate  Set  Leaders  if  necessary.  All  of  the  set creation, administration and control functions can therefore be carried out by any node of the system and provision is made to assume the function at a new node when failure or partition in the network occurs.

Granted: 2004-03-30
Abstract: The invention relates to an advanced composite structural component, made of a polymer and wood fiber composite material, in the form of an extruded or injection molded thermoplastic member in residential and commercial structures. Preferably the structural component is used in a window or a door. Common window and door manufacture require the production of linear members with specifically designed cross-sectional shapes to form both the window frame structural elements and movable sash components. The structural elements must possess sufficient strength to permit the manufacture of a structurally sound window unit that can be readily installed into a rough opening and can cooperate with the wall structure to maintain structural integrity. The window or door should have sufficient strength to survive day-to-day use and abuse and to maintain window or door structural integrity after installation. The structural component has a hollow cross-section with at least one structural web and at least one fastener web formed within the component. The exterior of the extruded component is shaped and adapted for installation in a rough opening and to support window and door components. Such structural components have unique advantages and can be assembled in a thermoplastic weld process. Welding is performed by heating and fusing the heated surfaces together to form a welded joint having superior joint strength characteristics.
