Patent number: 8504720Abstract: A content engine receives a content request from a client, generates a result including one of a content-providing value and a redirection value in response to the content request, and selectively provides, to the client, one of (i) content when the result includes the content-providing value, and (ii) a redirection message when the result includes the redirection value, the redirection message including an extended domain name having a client identifier which identifies the client. The result can be used by a content router or content engine in deciding whether to provide content or a redirection. The decision to selectively provide can be based on client proximity to the content engines, past redirections, content size and type, content engine capacity, content availability and other factors.Type: GrantFiled: June 19, 2012Date of Patent: August 6, 2013Assignee: Cisco Technology, Inc.Inventors: Barbara Liskov, John F. Carr

Patent number: 8224986Abstract: The invention is directed to techniques in a computer, for processing a content request. In one arrangement a content engine receives a content request from a client, generates a result based on the content request, the result including one of a content-providing value and a redirection value in response to the content request, and selectively provides, to the client, one of (i) content when the result includes the content-providing value, and (ii) a redirection message when the result includes the redirection value, the redirection message including an extended domain name having a client identifier which identifies the client. The result can be used by a content router or content engine in deciding whether to provide content or a redirection. The decision to selectively provide can be based on client proximity to the content engines, past redirections, content size and type, content engine capacity, content availability and other factors.Type: GrantFiled: March 7, 2002Date of Patent: July 17, 2012Assignee: Cisco Technology, Inc.Inventors: Barbara Liskov, John F.

Patent number: 7516240Abstract: A technique can be used to obtain content (e.g., a live feed, pre-positioned content, etc.) from a content-originating device (a content source). The technique involves identifying a tree-based location-path having a series of locations which leads from the computerized device to the content-originating device. Each location includes a set of devices, and the set of devices of at least one location includes multiple devices. The technique further involves selecting a device-path from the computerized device to the content-originating device based on the identified location-path, and acquiring the content from the content-originating device from at least one of the devices along the selected device-path. The selected device-path includes at least one device of each location of the series of locations.Type: GrantFiled: May 19, 2005Date of Patent: April 7, 2009Assignee: Cisco Technology, Inc.Inventors: Barbara Liskov, John F. Carr

Patent number: 6232496Abstract: Amphoacetate surfactants are made by reacting a compound of formula RCONHCH2CH2NHCH2CH2OH where R is an aliphatic radical, with formaldehyde and a cyanide of formula: R1CN, wherein R1 represents a hydrogen atom or an alkali metal, and, when R1 represents a hydrogen atom, hydrolysing the nitrile obtained with an alkali.Type: GrantFiled: November 22, 1995Date of Patent: May 15, 2001Assignee: Rhone-Poulenc Chemicals LimitedInventors: John F. Carr, Peter Lees, Richard Stocks-Wilson, Derek Pakenham

Patent number: 4595218Abstract: An insulative coupling for coupling a first tube to a second tube for fluid flow therebetween. The coupling includes an insulative washer and an insulative bushing cooperating with a flange connector associated with one of the coupling body elements to provide an electrically insulative connection between the coupled tubes. An O-ring is utilized in conjunction with a face seal radially inwardly of the washer to provide a high pressure seal between the coupling elements. The washer and bushing include axially extending flange portions having snug fits with associated components of the coupling to provide for facilitated and accurate assembly.Type: GrantFiled: August 4, 1983Date of Patent: June 17, 1986Assignee: Imperial Clevite Inc.Inventors: John F. Carr, Leonard J. Kowal, Albert J. Schwarz

Patent number: 4381573Abstract: In a side (or heel seat and side) lasting machine, opposite side portions of the upper are clamped against the last, by means of clamp pads arranged in two rows one at each side of the last, prior to the lasting margin being wiped over corresponding marginal portions of the insole. To ensure that the upper lies snugly against the last prior to the in-wiping operation, the most heelwardly disposed pad of each row is so mounted that, as it is moved inwardly towards the last, it engages the upper at a position spaced from the feather line thereof, continued inward movement thereafter causing the pad to move towards the feather line, thereby causing an upward drafting of the upper. Said pads may be mounted to pivot or to be deflected to effect such upward draft. If desired, adjacent pads may be similarly mounted.Type: GrantFiled: July 2, 1981Date of Patent: May 3, 1983Assignee: USM CorporationInventors: James R. Flanders, David W. Halford, John F. Carr

Patent number: 4346072Abstract: Aqueous toothpaste containing abrasive particles of Bayer process alkaline alpha-alumina trihydrate which has been milled in the presence of a surface-modifying agent. Carboxylic acids containing a polar and a non-polar group and hydrophilic pyrogenic silica are surface-modifying agents. The toothpaste may be packaged in unlined aluminum tubes.Type: GrantFiled: September 12, 1980Date of Patent: August 24, 1982Assignee: Colgate-Palmolive CompanyInventors: Eric Baines, John F. Carr
