Abstract: A support tower for heavy loads or large structures such as a wind turbine generators, constructed of a plurality of telescopic tower sections with the outer lower tower section having a lower end supported from a foundation and at least one or more inner upper tower sections telescoped in an initial vertical nested relation within the outer lower tower section. The heavy load is mounted on an upper end of the inner upper tower section while in the initial vertical nested relation. The inner upper tower section or sections are then lifted upwardly to an extended tower height by lift mechanisms and the tower sections are secured in vertically extended position by inter-engaging wedge joint structure with bolt fasteners extending through mating wedge surfaces to retain the telescopic tower sections vertically extended and position the heavy load in a vertically elevated position.

Abstract: A stacker and cart are provided for vertically stacking forms fed from a printer, folder, or other mechanism, by a conveyor, which do not require tilting of the cart to allow offloading of the forms. The stacker has a housing with side walls parallel to and spaced from each other in a first dimension and a base which mounts the side walls so that they are inclined with respect to the vertical (e.g. about 15 degrees), tilted in a second dimension perpendicular to the first. A number of forms-supporting stacker tines are parallel to and spaced from each other in the first dimension, and an elevator mechanism moves the tines in unison generally vertically with respect to the side walls. A stacker cooperates with a cart, a part sensor mounted on or adjacent the stacker base, and a latch on the cart cooperating with a latching mechanism on the stacker.

Abstract: A floor frame assembly for modular housing units that includes longitudinally extending floor support beams, an outer end beam comprised of a pair of generally parallel angled members, and transverse supports that have a first end attached to and extending outwardly from an outer one of the longitudinal floor support beams and a second end attached to the angled members to support an edge section of the floor assembly. The second end has a height less than the height of the first end. For further support, the floor frame assembly includes vertical first stabilizing members installed at the second end of the transverse supports to keep the transverse supports from buckling.

Abstract: A floor frame assembly for modular housing units that includes longitudinally extending floor support beams and transverse supports that are attached to and extend outwardly from an outer one of the longitudinal floor support beams to support an edge portion of the floor assembly. The transverse supports have an outer end substantially less than the height of the end that is secured to the outer beam. A hanger is secured to the outer edge of each of the transverse supports. The height of the hanger is greater than the height of the outer end edge so that a gap is created between the bottom of the outer end and the bottom of the hanger to facilitate the attachment of the hanger to a sill plate of a foundation.

Abstract: Fan folded business forms are compacted so as to provide the maximum run time, and minimum operator effort. The system includes a folder, transfer table with compacting conveyor, and wheeled cart with a backstop on it. The backstop is continuously pushed along the cart by the compacting forms until it reaches a position at the end of the cart, at which time a cart full sensor operates an alarm and/or shuts off the folder. The compacted forms on the cart may be easily moved to any desired location. Forms may be fed either printed side up or printed side down into another piece of equipment. The main surface of the cart on which the forms travel with their fold lines engaging the main surface, may be manually tilted about a horizontal axis after the cart is full, so that the end of the cart from which forms are to be withdrawn is elevated. This provides efficient withdrawal of forms while minimizing curling of the forms.

Abstract: A remote controlled self-propelled vacuum cleaner comprising a manually held radio transmitter and a radio receiver installed in the vacuum cleaner. The vacuum cleaner is provided with a pair of freely rotating wheels driven by friction rollers on the ends of a driveshaft driven by an electric motor through an elastic belt. Each drive roller may be disengaged from the tire of the corresponding wheel by a solenoid operated lever. Lifting of a drive roller from a wheel tire causes the simultaneously application of a brake on the wheel such as to cause the vacuum cleaner to be steered in an appropriate direction. The electric motor is reversed for reversing the direction of motion of the vacuum cleaner. The steering solenoids and the direction of rotation of the electric motor are controlled by servos according to the command signals received by the radio receiver.
