Abstract: A powered rope ascender that supports a person or a load while ascending a vertical rope. The rope ascender has a motor driven capstan drum that engages the rope. A pinch roller grips the rope against the capstan drum. A load limiting assembly releases the grip by the pinch roller when the load supported by the ascender exceeds a predetermined amount. A centrifugal clutch reduces starting torque required by the motor and the outer drum of the centrifugal clutch interacts with a brake to hold position on the rope. For heavy loads a motion activated brake is used. Hand controls provide a freewheeling, a braking and an ascending mode of operation. A harmonic drive or planetary reduction gears provide speed reduction from the motor to the capstan drum. The powered rope ascender can be threaded on the rope without access to a rope end.

Abstract: A sport fishing system having: a rod and reel, including fishing line; at least one fishing lure or natural bait; and a controlled released fish attractant for applying to the fishing lure or natural bait. The system may further include an applicator for applying the controlled released fish attractant to the fishing lure or natural bait. In the preferred embodiment, the controlled release fish attractant includes: an attractant and a substantially hydrophobic, film forming release agent.

Abstract: Batch-mode and continuous-mode decomposition of nitrous oxide is used to provide multiple ignitions of a solid-propellant gas generator and subsequently control its output gas temperature and flow rate, respectively. To reignite the solid-propellant gas generator, a controlled mass of a reactive oxidizer, such as hot nitrous oxide decomposition products, is injected into the gas generator chamber.

Abstract: A fire starting flare suitable for hand-held launchers has a fuse and ignitor assembly within a flare core material such that as the flare is launched the fire ignites and as the flare lands the fuse reaches the ignitor assembly to set off the flare.

Abstract: A pistol style flare launcher device suitable for multiple launches of flares uses an orifice in a gas duct to control the burn rate of blank cartridges by predictable high back pressure and a deflector pin in the launcher barrel to block gas from said orifice from striking the flare and deflect the gas into a plenum which allows gas to expand to a lower pressure still suitable to launch the flare.

Abstract: A jet vane thrust vector control unit is provided to pitch a missile over to a generally horizontal path after the missile has been vertically launched. A collar affixed to the base of the missile by explosive bolts is utilized to mount the unit so that the unit can be jettisoned after it has done its job.

Abstract: A filter-cooler is provided for use with a rocket motor to cool and filter ighly aluminized hot gases from around 5800.degree. F. to around 2000.degree. F. The cooled and filtered gases are then usable, for example, in thrust vector control or other mechanisms associated with the rocket. In the present system the cooler section is placed ahead of the filter section so that alumina present in the gases begins to solidify ahead of the filter and thus may be more efficiently removed. The filter section comprises a plurality of graphite vortex producing geometries. The vortex direction of the baffles is reversed in succeeding baffles so that the net effect of the high rotational velocities of each vortex is used to separate the particulate contaminates from the gas stream by momentum.
