Abstract: An oscillator (100, 200) and a method of adjusting the frequency of oscillation of the oscillator (100, 200) are disclosed for generating a signal with an adjustable frequency in a frequency range from 1 GHZ to 200 GHz. The oscillator (100, 200) includes a loop circuit. The loop circuit has an amplifier (101), a delay element or filter (103), a phase shifter (102), a device for adjusting the phase shifter (102), and a coupler (104) to provide an output signal. The adjusting device is coupled to the phase shifter (102).

Abstract: The present invention relates to a gypsum board hanging tool that allows a single workman to hang gypsum board on a conventional or inclined ceiling. Specifically, the gypsum board hanging tool comprises a support housing, a wheel that is rotatably attached to the support housing, and a support strut which is removably attached to at least one extension of the support housing. The support housing also has a means whereby a support strut may be attached. The support housing also has a means an aperture in its upper surface that is capable of receiving, within the support housing, a hanging member, such as a nail or screw, that is first attached to a ceiling or a wall. The hanging member allows the support housing to be suspended from the ceiling and to adjust and swivel about the hanging member.

Abstract: The present invention relates to a media cutting tool for use with a template. The apparatus of the present invention maintains proper alignment with a template through the use of a novel offset, rotating, cutting blade and guards against skipping along the cut as the apparatus is drawn around a template through the use of a novel guide mechanism which engages the template being traced. The present invention also employs a transparent handle for an improved view of the cutting area.
