Patent number: 9563739Abstract: For a printed circuit board assembly (“PCBA”) selected electronic components are highlighted on a graphic representation of the PCBA on a display of a computer system. The components are selected responsive to temperature and time limits of the selected components. Ones of the highlighted components are associated to respective temperature sensors on the PCBA. Responsive to where the one or more additional ones of the highlighted components are located on the PCBA relative to the at least one of the respective temperature sensors, one or more additional ones of the highlighted components are associated with at least one of the respective temperature sensors. The computer system receives data for respective signals indicating temperatures encountered by the respective temperature sensors when the PCBA is heated in a manufacturing process. The computer system shows whether any of the time and temperature limits were exceeded during the manufacturing process.Type: GrantFiled: March 7, 2016Date of Patent: February 7, 2017Assignee: International Business Machines CorporationInventors: Mitchell G. Ferrill, Curtis Grosskopf, Matthew S. Kelly, Thomas H. Lewis, Wen Wei Low

Patent number: 9317643Abstract: A method for printed circuit board design of temperature sensitive components includes a scrub tool receiving a list of part numbers for electronic components of a printed circuit board assembly (“PCBA”). The scrub tool sends one or more queries for finding temperature and time limits of the electronic components to a database. A mapping tool receives a selection of one or more part numbers responsive to the one or more queries, wherein the selection is responsive to the temperature and time limits. The mapping tool sends a data structure to a physical design tool which is configured with physical design data for generating a graphic representation of the PCBA. The data structure from the mapping tool provides the received selection of one or more part numbers and configures the physical design tool to highlight components having part numbers of the selection on the PCBA graphic representation.Type: GrantFiled: May 22, 2014Date of Patent: April 19, 2016Assignee: International Business Machines CorporationInventors: Mitchell G.

Publication number: 20100080653Abstract: The present invention provides a compressible seal for installation in joints in concrete pavement, the machine for installing the seal and the method of installation. The seal is a preformed, closed cell, elastomeric cylinder or rope. The seal defines a round cross section in its relaxed, i.e., uncompressed, state somewhat larger than the joint into which it will be installed. The installation machine is a wheeled, hand powered device having a first guide wheel which is received within the joint, an aligned installation wheel which installs the seal in the joint, a second guide wheel which ensures that the seal is at the proper depth in the joint and a pair of contra-circulating belts which feed the seal to the installation wheel.Type: ApplicationFiled: September 26, 2008Publication date: April 1, 2010Inventors: Thomas H. Lewis, Eric I. Devine, Benjamin D. Jacobus, Jesse S. Mathey

Patent number: 5919596Abstract: Disclosed is an admixture which is curable to form a crack resistant, photosensitive polycyanurate resist. Also disclosed is a structure for its use and process of making. The resist can be tailored to be either positively or negatively sensitive to actinic radiation. Because of its improved thermal and mechanical properties, the cured resist is suitable for use at high temperature, such as in electronic packaging applications.Type: GrantFiled: February 11, 1997Date of Patent: July 6, 1999Assignee: International Business Machines CorporationInventors: Jeffrey C. Hedrick, Konstantinos Papathomas, Stephen L. Tisdale, Alfred Viehbeck, Jeffrey D. Gelorme, Voya Rista Markovich, Thomas H. Lewis, Stephen Joseph Fuerniss

Patent number: 4401540Abstract: An apparatus for reducing end effect in anodes used in cathodic protection systems for underground metallic structures and in which the anodes are surrounded by and are in intimate engagement with a carbonaceous material so that an impressed current which is supplied to the anode is discharged from the anode in a substantially uniform current discharge density which is maintained at a level that is electronically conducted by the carbonaceous backfill to the earth. The anode includes an elongated body of electrically conducting material having a plurality of non-conducting segments which separate the body into conducting areas of non-uniform size and which take advantage of mutual interference between adjacent conducting areas to substantially prevent electrolytic current discharge from the anode.Type: GrantFiled: October 29, 1980Date of Patent: August 30, 1983Assignee: C.E. Equipment Co., Inc.Inventors: Joe F. Tatum, Thomas H. Lewis

Patent number: 4175021Abstract: An apparatus for and method of preventing end effect in deep well impressed current anodes surrounded by a carbonaceous backfill in which the opposite ends of an elongated slender anode are of non-conducting material and the remainder of the anode includes a plurality of alternating segments of conducting and non-conducting material along substantially the entire surface length of the anode. The anode is connected to a source of impressed electrical current and the non-conducting segments cause a substantially constant impressed current density to be transferred from each of the conducting segments along the length of the anode as an electronic discharge and substantially prevents any electrolytic discharge therefrom.Type: GrantFiled: March 6, 1978Date of Patent: November 20, 1979Assignee: C. E. Equipment Co., Inc.Inventors: Joe F. Tatum, Thomas H. Lewis
