Abstract: A hybrid lightning protection system. The hybrid lightning protection system may include a mast assembly. The mast assembly may include an upper portion including one or more upper mast sections; and a lower portion including one or more lower mast sections, wherein the lower portion supports the upper portion and is connected to a lower most one of the one or more upper mast sections of the upper portion. The hybrid lightning protection system may further include a base mast section, wherein the base mast section supports the mast assembly and is connected to a lower most one of the one or more lower mast sections of the lower portion; and one or more lightning dissipaters disposed at a top portion of an upper most one of the one or more upper mast sections of the upper portion.

Abstract: A portable lightning protection system is described for placement adjacent structures requiring lightning protection. The system includes a base mast section with an upper end and a plurality of radially extending, axially aligned ribs; a top mast section; preferably at least one intermediate mast section attachable to the upper end of the base mast section and to the lower end of the top mast section, the mast sections being axially aligned when attached; an air terminal having a conductive rod insertable into the bore of the top mast section; a base including a plurality of radially extending horizontal beams having inner ends attachable to the base mast section ribs and a plurality of inclined beams having inner ends attachable to the base mast section ribs and outer ends attachable to the horizontal beams; and grounding cables connecting the mast to the ground.

Abstract: Broadcast towers used for the co-location of wireless antennas and having a plurality of antenna wires spaced from a support are modified with an insulation system including flexible, non-conductive insulation sleeves to cover the lower section of the antenna wires. These sleeves include an inner tubular member having an inner diameter greater than the outer diameter of the antenna wire and an outer tubular member having an inner diameter greater than the outer diameter of the inner tubular member. An improved cabinet for isolating cables is also described. The cabinet includes a conductive housing having a top wall, a bottom wall, and parallel first and second side walls joining said top and bottom walls, and removable front and back plates. A non-conductive cable support frame is slidable within the housing. The side walls have corresponding attachment openings, whereby a side wall of one cabinet can be aligned with and attached to a side wall of another cabinet of the same construction.

Abstract: A device for turning or moving a bedridden patient on a bed having opposed sides by pulling a sheet positioned under the patient toward one said of the bed, the device including a support frame with first and second vertical roller support arms, and a horizontal base connecting the support arms; a horizontal roller including sheet attachment clips supported by the support arms; an electric motor mounted on the frame and operatively attached to the roller through the interior of the frame; wheeled legs pivotally attached at their inner ends to the frame; and electrical circuitry controlling the operation of the motor, the circuitry including a timer for stopping operation of the motor after a predetermined time period, and wiring within the frame interior.

Abstract: A transportable broadcast antenna supported on a moveable carriage comprising a telescoping tower having plurality of nesting sections, including an outer section, and intermediate and inner sections, each section slidable relative to the adjacent exterior tower section between retracted, deployed and release positions, and latches to hold the section in the deployed position. The latches disengage when the section is further extended to the release position, and is prevented from locking when the tower is retracted. Radials join the tower and extending outwardly therefrom.
