Abstract: The Building Material Installation Support Hand Tool of the present invention comprises a strut assembly having a horizontal support bracket disposed in a transverse, T-shaped arrangement with a vertical strut device. The strut device incorporates an elongated tube open at its top and bottom ends. The tube telescopically receives an upper extremity of a lower leg of the strut device for coarse adjustment of the height of the strut device to accommodate standard, predetermined heights of ceiling and wall structures. An adjustment means of the strut device interconnects the tube and the leg and is actuateable by the worker to releasably lock the tube in a position relative to the leg. The strut device includes at a lower extremity of the leg a cleat adapted to grip a floor.

Abstract: A device for use as an electronic generator for generating a highly realistic flickering light is disclosed which has adjustable brightness, flicker rate, and flicker level to accurately simulate a variety of lighting effects such as fire, reflections from natural sources, and light from man-made sources. The device uses a pseudorandom output generator to generate a variable level analog signal which may be adjusted in frequency, with additional controls being added to control the level of the signal of the signal variation and the overall signal level. The resulting signal is then used to drive lamps through relays, with multiple channels being used in the preferred embodiment.
