Patent number: 11002082Abstract: A departure device couples to a bit using a connector that facilitates release of the bit from the departure device. The connector may be more millable than the departure device and can transmit axial and torque loads between the bit and the departure device. The connector may include a material having lesser strength or hardness than the departure device, and may be millable by the bit. Another example connector may have connection points with the bit, and a movable member of the departure device may a force to the connector and contribute to releasing the connection between the bit and the departure device. A tensile connector between the bit and the movable member may apply a tension force to the movable member, urging the movable member toward an extended position in which the movable member is aligned coherently with a sloped face of the departure device.Type: GrantFiled: June 16, 2016Date of Patent: May 11, 2021Assignee: Wellbore Integrity Solutions LLCInventors: Shantanu N. Swadi, Charles H. Dewey, Tuan Anh Nguyen, John Edward Campbell, Shelton W Alsup

Patent number: 9212873Abstract: A device for extending a shaft of an arrow including a hollow arrow sleeve having a forward end and a rearward end. The hollow arrow sleeve supporting at least one auxiliary, expandable, razor-sharp blade for pivoting movement between a stored position lying enclosed within the sleeve and a deployed position extending outwardly through a slot formed in the sleeve. The sleeve having at least one slot allowing passage of the at least one expandable razor-sharp blade from a stored position to a deployed position in response to movement of the at least one blade from the rearward position to the forward position relative to the sleeve. A member acting against the at least one auxiliary, expandable, razor-sharp blade for urging the blade toward the deployed position. A spring for biasing the member against the at least one auxiliary, expandable, razor-sharp blade.Type: GrantFiled: March 3, 2014Date of Patent: December 15, 2015Inventors: Christopher Michael Hartman, Ronald Mitchell Mcivor, John Edward Campbell

Patent number: 7152270Abstract: A wiper assembly wipes precipitation and debris of a windshield of a motor vehicle. The wiper assembly includes a drive motor fixedly secured to the motor vehicle. The wiper assembly also includes a wiper arm secured to the drive motor. The drive motor pivots the wiper arm across the windshield to clean the windshield. The wiper arm extends between a motor end and a distal end. The wiper arm also includes a separator extending along the wiper arm. The separator lifts the wiper arm away from the windshield allowing for the removal of debris from the windshield and the wiper arm.Type: GrantFiled: October 7, 2004Date of Patent: December 26, 2006Assignee: W3 Technologies, LLCInventors: Raymond M. Genick, II, John Edward Campbell

Patent number: 5671281Abstract: A system is disclosed for selectively altering the functional characteristics of a data processing system without physical or mechanical manipulation by providing an access code from a remote personal identification number generator to a secure controller and store of the computer system. This enables remote authorization of change in function of the computer system, such as performance tune up, speeding clock time, changing function and like changes. The computer system is first manufactured having a predetermined set of functional characteristics. A multibit alterable code which includes a functional characteristic definition is then initially loaded into physically secure, nonvolatile memory within the data processing system, utilizing an existing bus, or a fusible link which may be opened after loading is complete.Type: GrantFiled: August 10, 1994Date of Patent: September 23, 1997Assignee: International Business Machines CorporationInventors: John Edward Campbell, Michael James Chan, Steven Frank Hajek, Paul Leonard Wiltgen

Patent number: 4095283Abstract: A first in - first out auxiliary memory array for storing binary data wherein each member (word) of the array includes a special bit which is used in combination with the special bits of the other members comprising the same member set to form the address of the next member whose data is to be replaced. Each member comprises an identifier field, a data field and the aforementioned special bit. When a member set is addressed, each member of the set is read to determine whether there is a match on the respective identifier field. If there is a match, the data field of the same member is utilized. If there is no match on the identifier field of any member of the addressed set, the main memory is accessed for the necessary replacement information which is to be written into the member which contains the oldest data. The address of the last-named member is determined by the exclusive ORing of the special bits of all the members comprising the given set.Type: GrantFiled: July 2, 1976Date of Patent: June 13, 1978Assignee: International Business Machines CorporationInventors: John Edward Campbell, Gerhard Robert Thompson
