Patent number: 10600607Abstract: A device comprising an RF cavity enclosure including a tubular section having a plurality of interior structures radially or axially arranged which forms an unobstructed inner hollow center within the tubular section. Each interior structure of the plurality of interior structures includes side walls between which is formed an internal hollow sub-cavity. Resonating cavities exist between adjacent interior structures to produce a resonating frequency response. Vents are formed in at least one side wall for permeation of a gas into the internal hollow sub-cavity. A high-power microwave system and method of manufacture are provided.Type: GrantFiled: April 26, 2019Date of Patent: March 24, 2020Assignee: LOCKHEED MARTIN CORPORATIONInventors: Patrick M. Kelly, James-William B. Bragg

Patent number: 5844991Abstract: A computer-implemented method identifies a script used to create a document. A set of training documents for each script to be identified is scanned into the computer to store a series of exemplary images representing each script. Pixels forming the exemplary images are electronically processed to define a set of textual symbols corresponding to the exemplary images. Each textual symbol is assigned to a cluster of textual symbols that most closely represents the textual symbol. The cluster of textual symbols is processed to form a representative electronic template for each cluster. A document having a script to be identified is scanned into the computer to form one or more document images representing the script to be identified. Pixels forming the document images are electronically processed to define a set of document textual symbols corresponding to the document images. The set of document textual symbols is compared to the electronic templates to identify the script.Type: GrantFiled: August 7, 1995Date of Patent: December 1, 1998Assignee: The Regents of the University of CaliforniaInventors: Judith G. Hochberg, Patrick M. Kelly, Timothy R. Thomas

Patent number: 5191747Abstract: A prefabricated stainless steel appliance is provided for fast food restaurants that may be readily retrofitted into the preexisting pass-through openings in walls located between the kitchen area and the customer area. The appliance permits the serving of the customer with food with reduced personnel because of the elimination of frequent trips to the kitchen area from the customer area and return. The appliance includes an upper shelf for temporarily holding and keeping warm popular foods for readily serving.Type: GrantFiled: May 8, 1991Date of Patent: March 9, 1993Inventors: David C. Tengquist, Patrick M. Kelly

Patent number: 4969346Abstract: A cold-forming method is disclosed for thinning localized, longitudinally extending portions of sheet metal by lateral shear deformation without any substantial longitudinal deformation. With such method, it is possible to produce elongated members which are thinned in zones of low stress and are thicker in zones of higher stress so as to provide high metal use efficiency. The method is performed by an apparatus including a rotating mandrel providing opposed conical surfaces and pressure rolls operable to apply forces substantially perpendicular to the axis of rotation of the mandrel to cause a portion of the sheet metal to yield in shear to reduce the thickness of longitudinally extending portions of the sheet metal. The forces are applied in a plane normal to the length of the strip in order to avoid longitudinal elongation.Type: GrantFiled: July 19, 1989Date of Patent: November 13, 1990Assignee: USG Interiors, Inc.Inventors: George F. Bosl, Patrick M. Kelly, Dennis A. Alvarez, Gale Sauer, Joseph A. Hocevar

Patent number: 4876837Abstract: A drywall corner bead providing a rounded nose and two mounting flanges extending from opposite sides of the nose is formed from a strip of galvanized metal of uniform thickness. The two flanges are provided with three discrete longitudinally extending bands of reduced thickness formed by shear deformation of the material forming the band. The flanges are knurled to emboss the surface thereof and openings are formed in the flanges at intervals along their length. The corner bead is formed by a method in which shear deforming forces are progressively applied to the material forming the thinned bands to produce lateral deformation of such material without any appreciable lengthwise deformation. After the thinned bands are formed, forces are applied to straighten the corner bead. Subsequently, the flanges are knurled to provide an embossed surface and holes are punched in the flanges at intervals along their length.Type: GrantFiled: August 22, 1988Date of Patent: October 31, 1989Assignee: USG Interiors, Inc.Inventors: Patrick M.

Patent number: 4021624Abstract: An automatic call generator is connectable with the main distribution frame of a common control telephone system and monitors the operation of the system. To this end, the automatic call generator is connected to dedicated line and trunk circuit ports and attempts to place calls from one dedicated spot to another. If the system fails to terminate a call within a prescribed period of time, a malfunction is noted. Two malfunctions within a prescribed set of programs for monitoring the system cause a system alarm to be generated. The call generator also tests itself after proceeding through assigned programs for monitoring the system.Type: GrantFiled: October 23, 1975Date of Patent: May 3, 1977Assignee: Stromberg-Carlson CorporationInventors: Patrick M. Kelly, Alton Dorazio

Patent number: 3999085Abstract: A digital interface especially useful for isolating a speedily responsive circuit from the effects of transients at its input such as may be caused, for example, by contact bounce in a relay. The circuit includes a monostable multivibrator connected to be set in response to changes of alternately opposite polarity of the input signal and having a characteristic period equal to a predetermined fraction of the normal minimum interval between intended changes of the input signal. The output of the multivibrator is used to drive a flip-flop at the end of the characteristic period to produce the desired output signal. Thus, the circuit is non-responsive to relatively rapid alternations of the input signal immediately following a change of its condition, yet responds reliably when the input signal changes state and remains stable in its new state for a time exceeding the characteristic period of the multivibrator.Type: GrantFiled: July 14, 1975Date of Patent: December 21, 1976Assignee: Stromberg-Carlson CorporationInventors: Patrick M.
