Abstract: An improved snow and sleet detector having a pair of substantially parallel detector screens spaced one below the other, the upper screen being open to the ambient. A rim is included which is highly thermally conductive and electrically conductive and encompassing the upper screen proximate the edges thereof. A thermostatically controlled heater is mounted in intimate thermal and electrical contact with the rim for maintaining the rim and detector screens at a temperature high enough to melt snow or sleet falling thereon. Circuiting is described for providing an electrical indication when the detector screens are conductively coupled by melting snow or sleet.
Abstract: A bed frame constructed of detachable and interchangeable components to enable the width of the bed frame to be varied to supportingly receive standardized bedding, box springs, or the like, of different standard widths by interchanging components. Unique detachable interconnections are provided to enable assembly and disassembly of the bed frame and variation in its width without the use of tools or separate fastening clamps, nuts, bolts, or the like. The bed frame includes unique side rails of triangular seamless tubing having telescopically attached end brackets for supporting a headboard and/or footboard and a supporting leg assembly permanently attached adjacent each end of the side rails with box spring supporting clips detachably supported from the rail and leg assembly by the use of a socket in the upper end of the leg and a depending tongue on the box spring clip.
