Patent number: 8852328Abstract: Rotary fluid processing systems and associated methods are disclosed. A purification system in accordance with the particular embodiment includes a rotatable adsorbent-containing heat/mass transfer element that is generally symmetric about a rotation axis, and includes multiple radial flow paths oriented transverse to the rotation axis and multiple axial flow paths oriented transverse to the radial flow paths. The axial flow paths and radial flow paths are in thermal communication with each other, and are generally isolated from fluid communication with each other at the heat transfer element. Particular embodiments can further include a housing arrangement having multiple manifolds with individual manifolds having an entry port and an exit port, and with individual manifolds having different circumferential locations relative to the rotation axis.Type: GrantFiled: December 11, 2012Date of Patent: October 7, 2014Assignee: Prometheus Technologies, LLCInventors: John A.

Patent number: 7428585Abstract: Using parental controls includes storing parental control information on a user device and receiving a request from the user device to access a destination over a communications network. Parental control information stored on the user device may be used to determine whether to grant the request from the user device. When the parental control information indicates that the request should be allowed, the user device allows access to the destination. When the parental control information indicates that the request should be denied, the user device denies access to the destination. Information that is related to the parental control information stored on the user device may be stored on a remote device. The parental control information stored on the user device may be verified using the information stored on the remote device.Type: GrantFiled: July 31, 2003Date of Patent: September 23, 2008Assignee: AOL LLC, a Delaware Limited Liability CompanyInventors: John Barclay Owens, II, Patrick Meenan

Publication number: 20050042509Abstract: A battery terminal is configured to be secured to a battery case and includes a terminal assembly, and a ring. The terminal assembly includes an insert having a threaded bore, and an outer metal portion having a base with an annular flange configured to engage the inner surface of the case. The terminal further includes an anti-turn system with a first set of angularly-spaced bosses with intervening slots formed on a boss on the case, a second set of angularly-spaced bosses with intervening slots on a first side of the ring facing the case, which are complementary to the first set to form interlocking features. A set of recesses on the opposite side of the ring is configured to receive spun-over lead material during final finishing to form another pair of interlocking features. The exterior spun battery terminal eliminates corrosion that would otherwise occur due to cold worked lead contacting acid.Type: ApplicationFiled: September 8, 2004Publication date: February 24, 2005Inventors: Tony Key, John Barclay, Steven Kensinger

Patent number: 6758046Abstract: A slush hydrogen production device (10) utilizes a hydrogen slushifier magnetic refrigerator (30) having a wheel (50) of material exhibiting the magnetocaloric effect. The wheel is rotated through a magnetic field of varying intensity around the circumference of a wheel housing (36) created by the windings of superconductive magnets (56). The material of the wheel (50) follows a magnetic Carnot cycle as the wheel rotates (36) through regions of low temperature heat transfer and high temperature heat transfer. Liquid hydrogen is supplied to the regions of low and high temperature heat transfer through inlet pipes (39 and 42). Gaseous hydrogen is produced in the high temperature heat transfer region and vented away by an outlet pipe (48). Solid hydrogen is produced in the low temperature heat transfer region by direct solidification upon the magnetic wheel (50); and is removed by scrapers (76) and deposited in a compartment (26) where it mixes with liquid hydrogen to form slush hydrogen.Type: GrantFiled: August 22, 1988Date of Patent: July 6, 2004Assignee: Astronautics Corporation of AmericaInventors: John A.
