Patent number: 6521009Abstract: A reverse flow air filter arrangement is provided. The arrangement includes a filter element having first and second end caps, the second end cap having a central drainage aperture. A funnel shape on an interior surface of second end cap is used to direct moisture flow to the drainage aperture. The arrangement includes a housing in which the filter element is positioned, operatively, during use. Certain features in the housing facilitate moisture withdrawal from the filter element while also inhibiting interference with sealing between the filter element and the housing.Type: GrantFiled: October 9, 2001Date of Patent: February 18, 2003Assignee: Donaldson Company, Inc.Inventors: Donald Francis Engel, Dolan Bartels, John Hacker, Bruce Crenshaw, Don Harold

Patent number: 6330321Abstract: An on-demand teleconferencing system and method for setting up an on-demand conference call in a telecommunications system having the Advanced Information Network (AIN) architecture with system signaling the number 7 (SS7) and a Public Switched Telephone Network (PSTN). A subscriber is assigned an on-demand conference call number. When that number is dialed into the PSTN, it is identified by the PSTN that the dialed number requires handling by the SS7. The SS7 links the dialed number to a conference allocation and control system (CACS) which is connected to a plurality of scalable bridge servers. The CACS selects bridge servers available to handle the conference call and based upon a selection criteria such as a peak load sets up the on-demand conference call in one of the selected bridge servers.Type: GrantFiled: January 29, 2001Date of Patent: December 11, 2001Assignee: Voyant Technologies, Inc.Inventors: Donald Francis Detampel, Jr., Ronald D.

Patent number: 6256792Abstract: A glove principally for use as a catching glove by a hockey goalkeeper has the usual finger pocket with an outer side for overlying the goalkeeper's knuckles, and further comprises a hockey stick retainer which overlies a portion of the outer side of the finger pocket and is connected to a control mechanism for controlling movement away from this outer side portion. The retainer has a stiffness such that, with the control mechanism acting on the retainer, a hockey stick can be held firmly between the outer side portion and the retainer while all the goalkeeper's fingers remain in the finger pocket means. The glove can hold a hockey stick or like article without requiring any use of the thumb, and can also be used in other sports, and in other situations, where a player or a user does not have an operative thumb.Type: GrantFiled: May 31, 2000Date of Patent: July 10, 2001Inventor: Donald Francis MacDonald

Patent number: 6161145Abstract: In a data processing environment where a client requests a server to perform part of its processing, a method of updating the client's version of server-related data without requiring the client to be a server, includes steps of: receiving, at a control point server, a first request from the client requesting that server-related data be transferred from the control point server to the client; and in response to the first request, sending the server-related data from the control point server to the client, along with a unique bind token identifying a version number of the server-related data such that each time the server-related data changes a new unique bind token is associated with the data, where the client uses the server-related data to form a second request for the server to perform part of the client's processing, and where the client sends said bind token to the server as part of the second request.Type: GrantFiled: May 8, 1997Date of Patent: December 12, 2000Assignee: International Business Machines CorporationInventors: Andrew John Bainbridge, Stephen James Cocks, Donald Francis Ferguson, Thomas Freund, Avraham Leff, Glyn Normington, James Thomas Rayfield, Robert Anthony Storey

Chemical mechanical polishing of multiple material substrates and slurry having improved selectivity
Patent number: 6114249Abstract: A colloidal silica slurry containing triethanolamine is used in a chemical mechanical polishing process to polish multiple material substrates, such as silicon wafers containing silicon oxide where a thin underlayer of silicon nitride is used as a stop layer. The colloidal silica slurry containing triethanolamine is capable of achieving an oxide to nitride selectivity during polishing up to a demonstrated ratio of 28:1.Type: GrantFiled: March 10, 1998Date of Patent: September 5, 2000Assignee: International Business Machines CorporationInventors: Donald Francis Canaperi, Rangarajan Jagannathan, Mahadevaiyer Krishnan, Clifford Owen Morgan, Terrance Monte Wright -
Patent number: 6088768Abstract: A method and system for providing cache coherence despite unordered interconnect transport. In a computer system of multiple memory devices or memory units having shared memory and an interconnect characterized by unordered transport, the method comprises sending a request packet over the interconnect from a first memory device to a second memory device requiring that an action be carried out on shared memory held by the second memory device. If the second memory device determines that the shared memory is in a transient state, the second memory device returns the request packet to the first memory device; otherwise, the request is carried out by the second memory device. The first memory device will continue to resend the request packet each time that the request packet is returned.Type: GrantFiled: December 28, 1993Date of Patent: July 11, 2000Assignee: International Business Machines CorporationInventors: Donald Francis Baldus, Nancy Joan Duffield, Russell Dean Hoover, John Christopher Willis, Frederick Jacob Ziegler
