Abstract: An apparatus for detachably-attaching a first half of an electrical connector to a second half includes an exterior first half housing as part of the first half that rotates about a split ring with respect to a remaining interior portion of the first half. The interior portion does not rotate. The first half housing rotates during connection as the interior portion is urged longitudinally. Electrical sockets and electrical contact pins are provided in the first half and the second half. The first half housing includes inward-protruding pins that engage with outward facing slots of the second half and follow the contour of the slots as the first half housing is rotated causing a longitudinal displacement of the first half with respect to the second half. The slots and housing structure prevent flame propagation by providing complete electrical disconnection before a final mechanical release of the bayonet connection occurs.

Abstract: An apparatus for detachably-attaching a first half of an electrical connector to a second half includes an exterior first half housing as part of the first half that rotates about a split ring with respect to a remaining interior portion of the first half. The interior portion does not rotate during coupling. The first half housing rotates during connection as the interior portion is urged longitudinally. Electrical sockets and electrical contact pins are provided in the first half and the second half. The first half housing includes inward-protruding pins that engage with outward facing slots of the second half and follow the contour of the slots as the first half housing is rotated causing a longitudinal displacement of the first half with respect to the second half. First and second means in the slots prevent inadvertent separation from occurring. Means for preventing propagation of a flame are described.

Abstract: A method of fabrication of a rocket engine nozzle assembly using pressure brazing generally includes initially assembling a rocket engine nozzle liner into a rocket engine nozzle jacket for a rocket engine nozzle assembly. The rocket engine nozzle assembly may then be sealed. Prior to pressure brazing the rocket engine nozzle assembly, pressure brazing parameters may be determined. The pressure brazing may be performed with the determined pressure brazing parameters to complete the fabrication of the rocket engine nozzle. The rocket engine nozzle assembly may include a rocket engine nozzle jacket and a rocket engine nozzle liner having a plurality of channels, with the space between each channel defining a land, and the rocket engine nozzle liner having at least a pair of endlands disposed at each end thereof. The rocket engine nozzle liner is bonded to the rocket engine nozzle jacket by the endlands being bonded to the nozzle jacket and the lands being pressure brazed to the nozzle jacket.

Abstract: When a first pair of power connectors are inserted into a second pair of power connectors, the connectors are prevented from electrically and physically separating by a retaining clip that fits into the locking opening between the first pair of power connectors, and the locking opening between the second pair of power connectors.

Abstract: A channel cutting tool may include an arbor that connects to a rotating spindle of a machining tool or a similar spinning part of a machining tool. Two slot cutting blades may be fixedly mounted to the arbor. An inner washer may be fixedly mounted on the arbor between the cutting blades and establish the blade spacing. An outer washer may be rotationally mounted to the inner washer with a smaller thickness to facilitate rotation relative to the two cutting blades. The arbor rotates about a longitudinal rotation axis, which may also the rotation axis for the cutting blades, the inner washer, and the outer washer. The outer washer functions as a depth-limiting safeguard for the channel cutting tool.
