Title: Switching of balanced line-pairs in a cable management system with reduced number of crosspoint switches
Inventor: WISE JAMES H
IPC: H04Q3/52
Filed: 1994-11-07
Abstract: A cable management system which provides routing of wired services between service lines (16) and user lines (18).  Each service line enters the cable system at a service termination unit circuit card (22) which also holds a portion of a crosspoint switch matrix (126). Each user line enters the system at a line termination unit circuit card (20).  The service termination unit circuit cards are all mounted to connectors (36) on a first side of a centerplane board (24) and the line termination unit circuit cards are mounted to connectors (36) on the other side of the centerplane board.  Pins (37) extending through the centerplane board interconnect the connectors on the opposed sides of the centerplane board so that any service line can be connected to any user line.  A system controller card (26) mounted to the centerplane board communicates with the circuit cards via a bus (38) on the centerplane board.  When the service lines and user lines are made up of balanced line-pairs (218, 224, 222, 226), in order to reduce the number of crosspoint switches (238) in the crosspoint switch matrix (228), the differential signals on the balanced line-pairs (218, 226) are converted to single-ended signals on individual lines (240).  The individual lines are switched through the matrix and the signals thereon are then reconverted back to differential signals on balanced line-pairs (222, 224).

Inventor: DAUDI ANWAR R
IPC: B21D53/30
Filed: 1994-12-12
Abstract: Expanding apparatus and method for sizing a one-piece drop-center wheel rim having first and second ganged arrays of rim sizing die segments insertable into the rim from one side thereof, and a third array of rim sizing die segments insertable into the opposite side of the rim, all three arrays cooperating to form a complete array of die segments for expansion sizing of the rim. A single wedge mechanism moves thearrays radially outwardly to individually size the inboard bead seat, outboard bead seat and drop-center well zones of the rim in response to relative coaxial movement of the wedge and arrays in a rim expansion working stroke along a longitudinal axis of the wedge. The wedge includes an expansion cone mechanism comprising first, second and third cone-cams respectively individually operably associated with the first, second and third die arrays for radially expanding the same in such working stroke. A set-up adjustment mechanism disposed interiorly of the wedge has threeconcentrically arranged lead screws individually threadably coupled to each of the cone cams for carrying and selectively positioning the same along the longitudinal axis of the wedge to thereby vary the set-up end limit of radially outward movement of the associated die segment array for a given relative working stroke of the wedge means and arrays. A gear drive coupled to the exterior end of each lead screw individually rotates, and is driven either manually or by the same servo motors operably coupled to each worm gear drive. Cone cam position sensors each developa signal indicative of the axially adjusted set-up position of each associated cone cam. A signal processing control system utilizes the signals for controlling the servo motors to drive the cone cams and thereby control their adjusted set-up positions.

Title: Method and apparatus for configuring fabrics within a fibre channel system
Inventor: STOEVHASE BENT
IPC: H04L69/14
Filed: 1995-07-20
Abstract: A method and apparatus for configuring a system that includes a plurality of interconnected components that each supports service parameters for communicating with other components in the system.  A determination is made as to which components support service parameters that are compatible, and groups of components having compatible service parameters are identified.  Adjacent components exchange information frames that identify their service parameters.  Each component compares its service parameters with those of its adjacent components to determine whether they are compatible, updating its own service parameters if necessary.  Any component that updates its service parameters issues another information frame.  Thus, information frames are exchanged until it is determined which components support compatible service parameters, and what service parameters are to be used for communicating among those components. Additionally, a unique address is automatically assigned to every port in the system.  Control over the entire range of available addresses is initially granted to a master component, which assigns unique addresses to its own ports, and then relinquishes control over ranges of addresses to other components which each becomes the managers of the addresses over which it is granted control.  Each address manager assigns unique addresses to its ports, and if any extra addresses are available, relinquishes control over those extra addresses to another component.

IPC: C30B29/18
Filed: 1994-05-23
Abstract: The present invention is a filtering flow guide for hydrothermal reaction vessels - such as crystal growth apparatus - which improves crystal production efficiency and crystal quality without significantly slowing down flow velocities or crystal growth times. One embodiment of the flow guide fits inside a conventional hydrothermal autoclave for crystal growth, and includes at least one central inlet conduit by which crystal nutrient solution flows from the autoclave's dissolving zone into its growth chamber. A plurality of funnels encircle the inlet conduit, the funnels contaguous with each other along their lateral edges and with the inlet conduit's intake opening at the funnels' innermost edges. Each funnel may be substantially shaped as a hollow, inverted triangular pyramid with a nadir instead of an apex, the nadir opening into a filter-containing outlet. The inlet conduit, plurality of funnels and outlet tubes guide the flow of crystal nutrient solution optimally through the autoclave's dissolving and growth chambers, producing an even flow rate and pattern, and reducing wasteful crystal deposition. The inlet conduit, the funnels, or both elements, may further include optional filters positioned to enhance convective solution flow with minimal flow impedance. The flow guide thereby also filters out contaminants, producing high-purity, high-perfection crystals.
