Publication number: 20060021216Abstract: A connector axial compression tool having a lever end and a cable end, with a body slidably supporting a cradle in a cavity formed in the body. The cradle is slidable via a handle which pivots about the body, linked to the cradle by a lever mechanism. The cradle has a shoulder clamp adapted to mate with a connector body. Operation of the handle moves the cradle towards and away from a cable end of the cavity, against a cable clamp through which the cable may pass but against which a cable clamp sleeve of the connector abuts, axially compressing the connector to couple it to the cable. Because the shoulder clamp holds the connector body rather than pressing against the connector interface, a wide range of different connectors may be used with the same tool, without causing damage to the connector interface of the various connectors.Type: ApplicationFiled: July 30, 2004Publication date: February 2, 2006Applicant: ANDREW CORPORATIONInventors: Nahid Islam, Joon Lee, David Ball

Publication number: 20050135256Abstract: A partial best path technique distributes route selection in a routing protocol implementation on a router. The technique also ensures that announced paths received from peers of the router (i.e., a “load”) are compared in a correct order to select best paths that are then used by the router to forward packets and to advertise to the peers. When employed in a distributed architecture, the technique further reduces memory usage. To that end, the partial best path technique enhances a best path selection algorithm executed by the router to enable dispersion of the received path load among processing nodes or elements of the router, while maintaining the ordering requirement of the algorithm. The partial best path technique essentially provides an enhancement to the best path selection algorithm that selects a subset of paths from a plurality of paths, with that subset being the minimal subset needed to select the best paths.Type: ApplicationFiled: December 23, 2003Publication date: June 23, 2005Inventors: David Ball, R. Bennett, Martin Hesketh, John Scudder, David Ward

Publication number: 20050074003Abstract: A distributed software architecture implements a routing protocol as a set of processes running on a set of processors of a router. The distributed processes cooperate in a manner that internally exploits the distributed set of processors, yet externally presents an appearance/behavior of a single routing protocol process communicating with its peers in the network. The distributed nature of the architecture is achieved without altering the fundamental routing protocol, but by apportioning certain functions/tasks of the protocol among various processes in the multiprocessor router.Type: ApplicationFiled: October 2, 2003Publication date: April 7, 2005Inventors: David Ball, R. Bennett, Martin Hesketh, John Scudder, David Ward

Publication number: 20050067551Abstract: A concrete mold device for vertically forming a concrete panel includes a plurality of concrete forms for collectively defining a mold cavity for receiving an uncured concrete mixture therein. The concrete forms can include a pair of opposing side wall forms to define side wall surfaces of the mold cavity and a pair of opposing end wall forms to define end wall surfaces of the mold cavity. An elongate lower support gasket can also be provided and can have an upper surface that defines a bottom surface of the mold cavity. The lower support gasket can have gasket side walls to abut against at least a portion of each of the side wall forms to provide a seal between the lower support gasket and the side wall forms to retain the concrete mixture within the mold cavity.Type: ApplicationFiled: September 30, 2003Publication date: March 31, 2005Inventors: William Baker, David Balls, Daniel Balls, Clyde Allen

Publication number: 20050063366Abstract: In a telephone network, an intelligent peripheral (IP) provides a variety of auxiliary call processing functions, such as announcement playback and digit collection. In response to each call, the IP queries a service control point (SCP) over a data network, for instructions as to processing of the call. The IP runs software to select one SCP for control of each call, from a number of SCPs on the data network, and obtain the requisite instructions for the call from the identified SCP. For each call, the IP software identifies the telephone number of the subscriber and uses the NPA-NXX and D digits from that number to access a first mapping table and obtain a CLLI code identifying an SCP. Using the CLLI code from the first table, the IP software accesses a second mapping table to obtain the CLLI code for the mate to the identified SCP. Using the two CLLI codes, the IP also goes through the second cable to obtain all of the Internet Protocol addresses for the two SCPs.Type: ApplicationFiled: October 13, 2004Publication date: March 24, 2005Inventors: David Wheeler, David Ball

Patent number: 6464467Abstract: An involute spiral wrap scroll-type device uses two pairs of spiral wrap members connected together at opposite ends of a common rotational shaft. The device can be operated in either an expansion mode or a combination hybrid mode where each pair of spiral wrap members functions as a compressor and expander, respectively. In an expansion mode, electric current is produced via generator electrically responsive to shaft rotation. In hybrid mode, a first spiral wrap member pair functions as an expander with the second spiral wrap member pair functioning as a compressor. In this mode, the balance of shaft power between that produced by the expander and that absorbed by the compressor is either supplied by the motor/generator functioning as a motor, or converted into electricity by the motor/generator functioning as a generator. The housing can be hermetically sealed, thus promoting contamination-free operation.Type: GrantFiled: March 26, 2001Date of Patent: October 15, 2002Assignee: Battelle Memorial InstituteInventors: Timothy J. Sullivan, David A. Ball, Donald Anson

Patent number: 6109339Abstract: A heating system uses a dynamic thermal stabilizer for receiving, mixing, holding and outputting a circulating heat exchange liquid in a fashion similar to the use of a flywheel in the mechanical arts. Liquid is returned to the dynamic thermal stabilizer from both an input heat exchange unit and an output heat exchange unit. A two pump system affords a simple tee fitting arrangement that provides room air heating by directly using hot liquid either from the dynamic thermal stabilizer or directly (and at higher temperature) from the input heat exchange unit itself to automatically achieve an additional boost of room heat using higher temperature liquid. The system can also provide initial short draws of domestic hot water from the dynamic thermal stabilizer alone or long draws of hot water by using the input heat exchange unit as a further source of heat input.Type: GrantFiled: November 8, 1996Date of Patent: August 29, 2000Assignee: First Company, Inc.Inventors: Sherwood G.

Patent number: 4579128Abstract: A smoker's pipe comprises a bowl portion having a tobacco-receiving cavity below which is formed a transverse, tapering socket. A passageway interconnects the cavity with the socket. A tapering end portion of a stem part is a friction push-fit into the socket whereby the bowl portion can be rotated about the end portion of the stem part. The stem part includes a bore communicating directly with, and forming an extension of, the passageway. A primary reservoir in the lower regions of the bowl portion communicates with the bore and the passageway but is not in the direct path between the bore and the passageway, thereby keeping to a minimum the internal surface area of the pipe between the cavity and the bore. Thus the primary reservoir stores unwanted liquid in the pipe. Rotation of the bowl portion relative to the stem portion seals off the cavity from the reservoir and bore.Type: GrantFiled: March 8, 1984Date of Patent: April 1, 1986Inventor: David Ball
