Abstract: A helicopter rotor head system has direct mounted mechanical phasing and pitch control levers. The system reduces drag and friction from the conventional four-point connection used today by using a two-point connection at the swash plate. Input movements from the swash plate are transmitted through a linkage arm fixed to ball bearing raced levers. The levers are ball bearing raced in two positions, with two different inner race sizes to reduce wear and side load while maintaining precision and accuracy. These levers are mounted to fixed support studs on the center hub (yoke). This causes them to set the phase of the swash plate precisely. Movements from these levers are reduced to a single connection point and allow only pitch up/down movements that transmit to blade grips through a link rod.

Abstract: This invention describes the processes of formulating heat generating graphite-sodium silicate (G-S) coating agents/mixes, and coating these mixes on base layer boards/panels to construct moderate to high surface temperature heating devices that are environmentally safe, fire retardant, and economically viable. The core to such heating devices is the formulation of G-S coating agents/mixes that are composed of graphite, sodium silicate, and aluminum silicate. In these coating mixes, the graphite is the primary heat generating agent, the sodium silicate is the main fire resisting agent, and the aluminum silicate primarily serves as surface heat control and water proofing functions.

Abstract: A method of creating a camouflage device includes providing two bolts of lace with at least one of the bolts including pleated regions extending from one side to the other where the bolts are attached together. Each bolt of lace may include a particular pattern of stitches and/or coloring to further create more realistic three-dimensional camouflage system. Hems formed along the bolts of lace may include button holes and/or button or grommets for fastening a plurality of camouflage devices together.

Abstract: An apparatus for positioning poultry, meat, or fish product pieces on a conveyor and a system and method which utilize the inventive apparatus. The inventive apparatus comprises an array of side-by-side upwardly arched product channels and a plurality of catch members mounted for rotating through the product channels such that they lift and pull the product pieces through the upwardly arched product channels and then release the product pieces onto the conveyor.

Abstract: An abrasive pad having dots of abrasive material disposed thereon includes a central alignment hole. The abrasive pad is formed by slipping a backing pad having a central alignment hole onto an alignment stud that extends from a support surface through the central alignment hole. A mold having a plurality of fill holes and an alignment hole is then placed against the backing pad such that a portion of the alignment stud extends into the mold alignment hole. A mixture of abrasive material is deposited into the fill holes. Heat is applied and the mold is removed. The abrasive material is allowed to cure to create an abrasive pad having abrasive dots.
