    • An electron beam emitter includes an electron generator for generating electrons. The electron generator can have a housing containing at least one electron source for generating the electrons. The at least one electron source has a width. The electron generator housing can have an electron permeable region spaced from the at least one electron source for allowing extraction of the electrons from the electron generator housing. The electron permeable region can include a series of narrow elongate slots and ribs formed in the electron generator housing and extending laterally beyond the width of the at least one electron source. The electron permeable region can be configured and positioned relative to the at least one electron source for laterally spreading the electrons that are generated by the at least one electron source.

    • A self supporting electrical cable is provided which is especially of use in linear motion devices. The cable is in the form of a band having a crowned or curved cross-section. The band is self supporting and is typically employed in a looped configuration. The band is composed of a Mylar or other plastic or electrically insulating laminate with electrical conductors and reinforcing elements. The conductors are typically copper and the reinforcing elements are typically stainless steel. In use the cable is usually folded back on itself 180° to provide a loop configuration with a fixed radius loop end in which the loop is moveable along the direction of travel. One end of the cable is connected to the linear motion device, and the other end is connected to a stationary device.

    • A hoist system including a roller assembly which is allowed to pivot as a suspending member is rolled up around a drum compensates for lateral forces and allows a load on the suspending member to remain centered under the roller assembly. The drum has a shaft mounted through the center with a resilient coupling between the shaft and the drum which allows transfer of rotational torque while allowing the drum to pivot. Such a coupling can be furnished by a pair of concentric rings around the shaft having pivot holes orthogonal to the shaft axis. The innermost ring is connected by a pair of pivot pins to the shaft. The outermost ring is connected to the innermost ring by another pair of pivot pins perpendicular to the pivot pins through the shaft. The outermost ring is attached to the inside of the drum. The drum and outermost ring are allowed to pivot around the axis through pivot pins in the outermost ring, and the drum, outermost ring and innermost ring are allowed to pivot around the perpendicular axis through the pivot pins in the shaft.

    • A hoist system having triangular suspension bands minimizes sway and twisting during the lifting of a payload. The system includes three depending retractable and extensible triangular tension members which provide three sets of opposed horizontal tensile forces aligned along three non-parallel lines. Each tension member comprises a flexible triangular band attached along one side to one of three rotatable spools arranged at 60.degree. to each other. The bands are attached near their vertices to a payload gripper assembly which is raised or lowered as the bands are wound or unwound from the spools. The three triangular bands provide six horizontal force components which provide good lateral stability and torsional rigidity, thereby minimizing sway and twisting of the payload. The bands also provide good payload lifting strength.
