The fasteners secure the attachment depending from the cover, and the recesses prohibit complete rotation of the fasteners. | 02-03-2011 |
| 20110192848 | CLOSURE FOR PRESSURE VESSELS - A closure for pressure vessels provides ease in access to the inside of a pressure vessel and at the same time provides a tight pressure seal for the closure. The closure for pressure vessels includes a hub adapted to fit on to an opening on the pressure vessel, a door connected to the hub, a hinge assembly to secure the door to the hub, and a locking assembly attached to the door. The locking assembly includes a slide lock operating around a central support, a plurality of locking lug arms radially operating around the central support, a pressure alert valve connected to the door, and a handle connected to the slide plate operating around the central support. The handle moves the locking assembly from a locking position to an unlocking position as the result of the groove pattern machined in the back of the slide plate. | 08-11-2011 |
| 20110290802 | SYSTEMS AND METHODS FOR RESTRICTING ACCESS TO INFRASTRUCTURE COMPONENTS - Systems and methods for restricting access to infrastructure components are provided. In this regard, a representative system includes: a lock assembly having a receptacle, a sleeve, a fastener and a cap; the receptacle having a longitudinal bore; the sleeve defining an interior and having a first end, an opposing second end, and an interior flange positioned between the first end and the second end; the fastener having a shaft extending from a head, the shaft being sized and shaped to engage within the longitudinal bore of the receptacle, the head being sized and shaped to prevent passage of the fastener through the sleeve via interference with the first flange; the cap being operative to engage the second end of the sleeve such that, in an engaged position, the cap and the sleeve retain the head of the bolt within the interior of the sleeve; the lock assembly being operative to selectively secure the lid to the housing. | 12-01-2011 |
| 20120091140 | ENVIRONMENTAL-FRIENDLY PLUG FOR USED OIL FILTER - A used oil filter plug has a flat circular disc having an upper surface and a lower surface. A pair of mouse ear projections extends upwardly from the upper surface of the flat circular disc for thumb and forefinger leverage in turning the flat circular disc. A threaded stud extends downwardly from center of the lower surface of the flat circular disc. The threaded stud is sized to thread into an internally threaded central oil passage opening in an endplate of the used oil filter. This causes the lower surface of the flat circular disc to cover a plurality of oil passage openings in the end plate and bear against the rubber gasket seal ring preventing oil leakage therefrom, so that the used oil filter can be safely discarded without adversely affecting the environment. | 04-19-2012 |
| 20130008906 | CAP-INSTALLATION SIGNAL SYSTEM FOR FILLER NECK CAP - A filler neck cap is adapted to mate with and close a filler neck. The filler neck cap includes a closure configured to engage the filler neck, an outer handle configured to be gripped by a consumer, and a torque-transmission member configured to transmit torque applied to the outer handle by the consumer to the closure to rotate the closure relative to the filler neck during installation of the cap in the filler neck and removal of the cap from the filler neck. | 01-10-2013 |
