Abstract: Shelving patent emphasis appears to be concentrated on ventilated shelving. The shelving herein is for use with wall studs. The areas between studs in garages, basements, and attics usually constitute wasted space. This space is even less pleasing when free standing shelves are placed in front of studs. There is a need for shelves which effectively utilize the spaces between exposed studs. Stud shelves available commercially are only as deep as the depth of the studs themselves, and both hands are needed to screw or nail up one end of the shelf while the other end of the shelf dangles freely. The shelving herein extends beyond the front edges of the studs, and spikes support the shelves during installation.

Abstract: An optical projecting device accurately aligns figures, letters and symbols using images, and grid lines projected on a work area during such tasks as graphic design layout. Prior art solutions to the problem of eliminating penciled guide lines to improve such graphic design layout involve the projection of reference lines. But one drawback is that there is no provision for moving, repositioning, or partially rotating, the images and reference lines relative to the work piece during the design layout operation. Another is that they include no provision for changing the image sizes when required during the progress of the work. A different technology as well as different illumination precepts overcome prior art drawbacks. The unit is the type which includes a housing, a light source within the housing, and an image bearing transparent panel. But the transparent panel is carried in a retainer adapted to be rotated.
