Abstract: A method and apparatus for delivering a predetermined amount of material into a predetermined position on each of a series of moving trays while avoiding spillage of the product onto other portions of the trays. A conveyor lifts the material onto a shaker pan which delivers the material in an even flow on to a rotating turntable having a plurality of radially extending gutters thereon. The turntable directs the material to flow along the gutters and into a plurality of hoppers disposed at the periphery of the turntable. Once a hopper is full, any excess material falls onto a drip tray which returns the material back to a supply bin. The filled hoppers are sequentially rotated above the trays, which are moving on a conveyor, to release material onto a predetermined area of each successive tray. A funnel disposed between the hopper and the tray facilitates delivery of material onto the tray.

Abstract: In solid propellant rocket motors the size of the flowfield defined by the bore continually increases as the solid propellant is consumed. As a result, the efficacy of a rigid baffle decreases through the burn. By making the baffle flexible, it can be deformed to fit the small initial geometry and its expansion due to inherent resilience naturally accommodates the enlarging geometry of the propellant bore. Since the baffle is flexible, it can participate in the oscillations and thereby alter frequency and mode structure and also introduce nonlinear behavior. Thus, pressure waves propagating in one direction around the propellant bore lift a flap of the baffle and pass through the clearance. Pressure waves propagating in the other direction around the bore, however, press the flap against the surface of the bore to restrict the passage of such waves. As a result, the flexible baffle acts as a "check valve" to limit wave motion.

Abstract: A new type of stool cover had an air tight and hollow inside part of its seat-ring, with bottom that is fitted with drafting openings with fittings to plug up the openings. A plug system involves a support, a spring, a plug support, and a filler associated with each draft opening in the bottom of the seat-ring. The plug support and the filler are made of one piece. While the user is sitting on the seat-ring, the plug support moves upward against the spring, in turn moving the filler away from the drafting opening. The drafting openings are then just opened, and draft from their location on top of the stool. The bad smell produced in the stool can thus continually be avoided.
