Abstract: At least four alignment members, namely, an aim member 11, a guide member 12, and two positioning members 13, 14, may be arranged in various configurations to assist the golfer with putts and with wood and iron shots. A connector 25 is disposed at an end 27 of each of the guide and positioning members 12–14. A member-receiving passageway 29 is formed on each of the connectors 25 and extends generally perpendicularly to the elongated member 12–14 upon which the connector 25 is disposed.

Abstract: A light-conductive and transparent front panel 12 is mounted in a frame 11. One or more etched characters 22 are formed on a rear surface 17 of the front panel 12, and one or more photo-luminescent characters 16 is/are disposed in overlying relation to the etched character(s) 22. A strip of light emitting diodes (LED's) 14 are mounted in the frame 11 adjacent to a side wall 13 of the front panel 12. Mounting members 19, 20 are formed on the frame to position and hold the front panel in place.

Abstract: A curtain wall or paneling system for concealing and beautifying an existing structural wall features a pair of elongated, upper cap and lower sill-forming channel members which are attached in predetermined, vertically spaced relation on the existing wall and which support and hold a plurality of transversely spaced apart, vertically elongated metallic studs or pilasters and decorative wall panels. The length of the studs and wall panels are correlated to the spacing between and depth of the upper cap and lower sill channel members, so that they may be easily lifted into and out of engagement with the cap and sill channel members.

Abstract: The present solid state device generates variable interval, high frequency bursts of alternating current to dim or otherwise control a discharge lamp or the like, and features an adjustable duty-cycle burst control subcircuit that intermittently interrupts a pair of constant, phase-reversed, high frequency pulse sequences, thereby permitting variable interval bursts of the pulse sequences to reach a pair of semiconductor devices. The semiconductors alternately switch ON and OFF in response to the high frequency pulses applied thereto, thereby rapidly alternating the direction of current flow through a suitable inductor configuration which, in turn, is connected to the load.

Abstract: A ceiling-mounted attic door features a continuous outer panel of flame-resistant plaster board, an intermediate layer of thermal insulating material and marginal sealing gaskets and insulating strips arranged to thermally seal the marginal edges of the door when it occupies a normally closed position within its associated door opening.
