A portable toilet seat and stand for wilderness camping includes seat bar members, legs, and crosspieces designed to interlock under the weight of the user. A pair of feet are provided for engagement with the legs to prevent the legs from sinking into soft ground.

Abstract:
A compact flatbed page scanner for facsimile transmission is described. The apparatus uses a linear charge coupled imaging device (CCID) for both light detection and electronic scanning across the width of the page. Compactness is achieved by folding the optical path from the scanned line to the CCID. A moving carriage below a horizontal glass plate supporting the document to be scanned carries: the linear CCID, a lens for focusing an image of one scanning line of the page onto the CCID, an assembly of bar mirrors for folding the path of the light beam from the scanning line to the lens, and tubular lamps for illuminating the scanning line. The motion of the carriage beneath the horizontal glass plate permits scanning an array of parallel lines, equally spaced over the length of the page. In the apparatus described, scanning a complete page may be performed from 4 seconds to several minutes, depending on the bandwidth available for transmission.
