Abstract: A quick release mechanism for a girth band having a plurality of coupling portions with high lead angle threaded surfaces that engage and automatically unscrew when tension is applied to the girth band unless an arm disposed on one of the coupling portions is prevented from rotating with respect to the other coupling portions.
Abstract: An electromagnetic projectile launcher having a pair of conductive rails with a breech and a nozzle end and an impedance electrically connected across the conductive rails adjacent the muzzle end of the conductive rails, and a second impedance which increases as the distance to the muzzle decreases, is disposed in the muzzle end of the rails and in arcs confined within the muzzle to commutate the current to the first impedance to substantially suppress any external arc as the projectile exits from the launcher.
Abstract: A circular grooved honeycomb labyrinth seal having a plurality of arcuate base portions, a plurality of honeycomb-shaped cell portions extending radially inwardly from the base portion with a plurality of passages disposed adjacent the base portion, the passages being in fluid communication with each cell and with the upstream side and the downstream side of the honeycomb labyrinth seal.
Abstract: A thin wall, generally round wrapper or liner is installed within a heavy wall, rolled heat exchanger shell which has greater out-of-round tolerances than the wrapper and the wrapper is maintained in its round state by utilizing a plurality of different types of jacks disposed adjacent the tube support plates disposed within the wrapper.

Abstract: A fixture for supporting a sleeve and induction coil which encircles the sleeve to facilitate removal and replacement of shrunk-on sleeves on a shaft, the fixture having upper and lower portions electrically insulated from each other and standoff insulated studs and pads which support the sleeve and induction coil within the fixture to minimize circulating currents in the fixture and heating of the fixture.
Abstract: A method for removing and replacing shrunk-on sleeves on a shaft utilizing a fixture having upper and lower portions electrically insulated from each other and stand off insulated studs and pads which support the sleeve and induction coil within the fixture, the fixture having insulated parts which minimize circulating currents in the fixture that would result in heating of the fixture.
Abstract: A shock absorbing pad system for a missile launch tube, wherein the shock absorbing pad system comprises a continuously acting inner sheet, an outer segmented sheet and a plurality of chevron shaped struts disposed between the sheets. The continuously acting inner sheet provides compressive, shear, and tensile forces or a combination thereof to resist lateral shock loads and to restore the missile to its central location within the launch tube.
Abstract: A seal for a large annular space formed from a plurality of overlapping seal segments disposed in a circular array; each seal segment having step margins which overlap when the segments are abutting each other in a circular array, each seal segment also having a sealing portion disposed at an angle with respect to a base portion which fits a cylindrical surface, and there is a groove on the low pressure side of the seal portion adjacent the juncture of the seal portion with the base forming a one directional hinge between the base portion and the sealing portion.
Abstract: A diaphragm is disposed in the upper end of the launch tube to ensure circulation of air to control the temperature of the nose of a missile disposed in the launch tube.
Abstract: A shock absorbent seal having chevron shaped struts and cap disposed between arcuate shaped inner and outer pads, the struts and caps have grooves where they attach to the pads and a groove at the apex to make them flexible during initial compression and the grooves and thickness of the struts and cap can be varied to meet deflection and load requirements.
Abstract: A moisture separator reheater apparatus having a shell member and a plurality of tube members situated therein with the shell member having a plurality of cycle steam inlets and a plurality of cycle steam outlets disposed on opposite sidewalls. The tube members are disposed longitudinally in the shell member and include an inlet pass and an outlet pass with the inlet pass receiving a heating fluid on its interior while being exposed to cool cycle steam on its exterior. The outlet pass is situated between the inlet pass and the cycle steam outlets, with the outlet pass receiving on its interior heating fluid which has previously flowed through the inlet pass while being exposed to heated cycle steam from the inlet pass on its exterior. All inlet passes receive heating fluid from a common source.
Abstract: A switching system for commutating high DC current from a first to a second pair of conductors comprising a switching armature slidably engaging the first pair of conductors, insulating inserts disposed on the first pair of conductors adjacent the second pair of conductors and means for drawing two series arcs between the armature and the first pair of conductors as the current is commutated to the second pair of conductors.
Abstract: Resistive inserts are disposed in the breech of a projectile launcher to prevent excessive premature heating, to prevent premature movement of the projectile armature, and to prevent welding of the armature to the projectile rails during the period while the current builds up to the launching magnitude.

Abstract: A continuous tube welding method which locates each tube and then moves a welding torch in orthogonal X, Y directions to form a continuous weld over a plurality of tubes disposed in a plurality of rows. The tube location is indicated by a probe which also measures tube diameter.
Abstract: A self-cleaning orifice assembly, for draining unacceptable accumulations of water from pipes and vessels associated with a turbine, is herein presented and claimed. The invention includes a two-position, movable stem having therein a plurality of ducts and the orifice. Their relative diameters and the flow itself are utilized to prevent blockage of the flow path.
Abstract: A welding torch made of a high temperature plastic which fits over a tube intermediate the ends thereof for welding the juncture between the tube and the back side of a tube plate and has a ballooned end in which an electrode, filler wire guide, fiber optic bundle, and blanketing gas duct are disposed.
