Abstract: A frame or chassis for mobile homes and the like provides a pair of laterally spaced, parallel I-beams extending the length of the frame. Wood floor joists are mounted on top of the I-beams and extend laterally beyond the I-beams in both directions. One-piece uniriggers having substantial tensile strength but relatively minor column strength in compression are connected to their ends directly or indirectly to the ends of the floor joists. The uniriggers provide outrigger portions extending downwardly and inwardly to the adjacent I-beam and a cross member portion extending laterally between the I-beams. The uniriggers are welded to the bottoms of the I-beams and cooperate with the associated floor joist to provide a trusslike structure which prevents rolling action of the beams. The frame or chassis provides adequate strength and rigidity when the frame is being supported by wheels and axles for road transportation and also when the frame is supported at intervals around its periphery at a use location.

Abstract: Apparatus to remove dust, fibers, lint or other undesirable particles from air. Air ladened with dust, lint or other undesirable matter is drawn into a filtering housing to contact the surface of a rotatable screen-covered drum. The air passes through the drum while the particles remain on the drum surface. The air passes from a higher pressure area exterior of the drum into a lower pressure area within the center of the drum and is conveyed away. The particles are retained on the exterior surface of the drum which is covered by the fine mesh screen. The particles, which form a bat, are then separated from the rotating drum surface by being moved into contact with a smooth compressor roll cooperating with a flighted doffing to lift away the bat from the drum and drop it to a collection zone.A supplemental doffing roll with rigid flights is rotated parallel to the axes of the compression roll and flighted doffing roll in such manner as to interfere with the rotation of urethane flights of the doffing roll.

Abstract: An improved friction roller including arcuate sections applied to an external surface thereof, the sections configured to receive and engage a magnetic flexible element such as a cable, and including a magnetic field generating coil means for attracting the cable to the arcuate section and thereby to the frictional roller.

Abstract: A high angle conveying apparatus including a conveyor belt and a cover belt trained for movement in endless paths of travel. An improved roller assembly is provided for providing fully equalized pressure to the back face of the cover belt for improved performance.

Abstract: A system for decompacting modules of compacted seed cotton. The system includes apparatus moveable through the compacted modules to feed the cotton to a remote location for further processing. Improved electronic controls permit automatic activation of a containment door against the trailing face of the last module, automatic reversal of the apparatus after containment of the last module and automatic inactivation of the system in the event of a malfunction.

Abstract: Air filtering apparatus with electric controls for varying the speed of filtering as a function of the contamination within the air being filtered. Pressure sensing devices are provided at the input and output ends of the filtering apparatus. The sensing devices are coupled with the electrical controls to either speed up or to slow down the filter cleaning mechanisms when appropriate.
