Abstract: A door locking system includes a door movably mounted on a rail. The door includes rollers rollably coupling the door to the rail. An opener is coupled to the door. The opener positions the door in an open position and a closed position. A lock is coupled to the rail. The lock is in communication with the opener. The lock is automatically positioned in a locked position after the opener positions the door in a closed position. Thus, the door is retained in the closed position.

Abstract: The presently disclosed technology relates to carbon-on-carbon (C/C) manufacturing techniques and the resulting C/C products. One aspect of the manufacturing techniques disclosed herein utilizes two distinct curing operations that occur at different times and/or using different temperatures. The resulting C/C products are substantially non-porous, even though the curing operation(s) substantially gasify a liquid carbon-entrained filler material that saturates a carbon fabric that makes up the C/C products.

Abstract: A throttleable exhaust venturi is described herein that generates strong suction pressures at an exhaust outlet by accelerating an incoming ambient fluid stream with the aid of a venturi to high gas velocities and injecting a combustion exhaust stream into the ambient fluid stream at an effective venturi throat. A mixing element downstream of the venturi throat ensures that the mixed fluid stream recovers from a negative static pressure up to local atmospheric pressure. A physical and the effective throat of the venturi are designed to promote mixing and stabilize the ambient fluid flow to ensure that high velocity is achieved and the effective venturi is operable over a variety of combustion exhaust stream mass flow rates.

Abstract: Embodiments described herein provide various processes for bonding metals to composites and for reinforcing the bonded metal and composite structures. In addition, the embodiments include the metal/composite compositions resulting from these processes.

Abstract: The present invention relates generally to subterranean well construction, and more particularly, to improved methods for producing gas from subterranean formations that include coal seams. The method according to the present invention includes the steps of drilling at least one substantially vertical well bore intersecting the coal seam, drilling at least one substantially horizontal well bore disposed substantially within the coal seam and exiting from the at least one substantially vertical well bore, and fracturing the coal seam along the at least one substantially horizontal well bore using a hydrajetting tool to produce a plurality of fractures. The plurality of fractures is spaced to maximize interference between the fractures and enhances the production of gas from the coal seam of the subterranean formation. A plurality of substantially horizontal well bores can also be drilled.
