Abstract: A molding apparatus includes a movable molding surface with molding cavities, a pressure shoe with a stationary outer surface that defines in cooperation with the molding surface a pressure zone, and a resin source configured to introduce molten resin into the pressure zone to be forced into the molding cavities by pressure in the pressure zone. The molding surface is movable with respect to the pressure shoe to introduce molding cavities to the pressure zone to be filled with resin while the outer surface of the pressure shoe and the molding surface define in between an entrance gap of decreasing width upstream of the pressure zone. The outer surface of the pressure shoe is spaced from the molding surface in the pressure zone to define a minimum gap at which the outer surface of the pressure shoe has a slope parallel to the molding surface.

Abstract: The paver installation system includes a grid having a plurality of mounting holes for selective installation of spacers, a flexible edging and a screed guide rail. The screed guide rail may be selectively installed on the grid via mounting pegs mounted in select mounting holes for screeding an intermediate layer of aggregate material between the grid and the pavers to be laid thereon. The flexible edging is attached to the grid in order to set the edges of the pavement to be laid, and the flexibility thereof easily accommodates curved edges by bending to conform to the curves. The spacers are laid onto user selected mounting holes in the grid in order to serve as guides for laying pavers in a desired pavement pattern and to maintain spacing between adjacent pavers.

Abstract: A paint repair process is provided for repairing scratches (12) and chips (22) in automotive paint (14). A paint mixture (26) is applied to the surface (24) of the automotive paint (14) and worked into the scratches (12) and the chips (22) by applying a minimum pressure of approximately one and one-quarter pounds per square inch directly to the paint mixture (26). After an initial drying of the paint mixture (26), the paint mixture (26) is polished and heated by applying a polishing mixture (28) to the surface of the paint mixture (26), and then pressing a natural wool fiber polishing pad against the surface of the paint mixture (26) with a minimum pressure of two pounds per square inch and moving the polishing pad relative to the outer surface of the paint mixture (26) at speeds in a rage of approximately 800 to 1050 feet per minute.

Abstract: A bypass seal for a rotary regenerative air preheater includes primary and secondary seal leaves that are joined at a single position longitudinally intermediate their first and second sends. The first end portion of the primary seal leaf extends longitudinally beyond the first end of the secondary seal leaf and the second end portion of the secondary seal leaf extends longitudinally beyond the second end of the primary seal leaf. When installed in the air preheater, the first end portion of the primary seal leaf of each bypass seal in one of the seal rings overlaps the second end portion of the secondary seal leaf of an adjacent bypass seal in the seal ring.

Abstract: There are various ways to latch a closure onto a container. It has been found that for blowmolded containers that the support flange for the bottle preform can later be used as a part of the latch mechanism to secure a closure onto the container. Preforms have a support flange by which the preform is handled prior to being placed into the mold and in the mold. Prior to being placed in the mole, the preform is heated to about 85oC to about 200oC. During this time and in the mold, it will be supported by the support flange. This support flange is used after the container is blown and filled as one part of the latching mechanism of the closure. The closure will have a portion that is an interference fit with the support flange of the bottle to thereby secure the closure to the bottle.

Abstract: Method and apparatus are disclosed for canceling local oscillator feed thru in an IF transmission circuit. The apparatus includes first and second mixers for receiving LO and IF signals. The mixers are operable to upconvert the IF signal while passing an attenuated and phase shifted portion of the LO signal. Bias regulation circuitry is provided for regulating the attenuation and phase shift of the LO signal portion passed by at least one of the mixers such that the LO signal portions are combinable to cancel each other. A coupler circuit is provided for combining the mixer outputs such that the LO signal portions are substantially canceled and an upconverted IF signal remains. The bias regulation circuitry may be self-correcting to optimize cancellation of the LO signal portions.

Abstract: A handling system for lowering and retrieving large and heavy objects such as sonar arrays from surface ships and other unstable platforms. A submersible object which normally is suspended by a single cable when at operating depth is retrieved and returned to a surface platform by a messenger device suspended on two or more other cables from the platform and provided with means for guiding the messenger to the object, orienting the object with respect to the messenger and thus with respect to the surface platform, and locking the messenger and object together. The resulting messenger and object assembly then may be hoisted back to the platform with some or all of the weight of the assembly carried by the messenger cables thus at least partially unloading the main support cable during retrieval.

Abstract: This energy absorbing bumper mount comprises a spring bracket assembly which includes a pair of diverging spring arms that carry pins on the outer end thereof. A preloaded yieldable energy absorbing band of oriented plastic material is stretched across the arms by attachment to the pins. On impact of a bumper attached to the spring arms, the pins are laterally displaced from one another as the spring arms are deflected. Energy is absorbed by the stretching of the band and by deflection of the spring arms. Rebound is controlled with the slow recovery rate of the band acting as a buckling column to retard recovery of the spring arms to their normal undeflected position.
