摘要： A fragrance disperser in one form includes a single fan that passes air over a wicked single or double fragrance. A second form has the fan reversible to provide two different airstreams that evaporate respective different fragrances one after the other. Where two fragrances are provided, the evaporation may be by respective electrical heaters. A fragrance source may be formed by two sheets joined together to form two chambers each receiving a respective wick and having respective exposed wick portions. The source may incorporate a source of electrical power. An alternative source has a reservoir for fragrance and a wick located in an air passage forming part of the source so that an air flow is guided through the passage past the wick to evaporate fragrance. Where two fragrances are provided, the fragrance sources may be located side-by-side and matching fragrances may have, for example, matching indicia on the sources so that the match can be easily determined visually.

摘要： A portable, self-illuminating traffic sign having a sign face with two opposite sides. One side indicates a first traffic signal, and the other side indicates a second traffic signal. Light assemblies are attached to each side of the sign. The light assemblies emit light that may match the predominant color of one of the sides of the sign. A battery may be disposed in a pole that connects to the sign. A handlegrip allows for the sign to be held and provides a switch to allow for the lights to be selectively turned on and off. The light assemblies are disposed within collar assemblies so as to reduce, or prevent, light emitted from the light assemblies reflecting off of the sign faces.

摘要： The hoist includes a rotatably mounted drive sheave having a continuous circumferential groove within which the load cable is received. A flexible bandlike member extends about the cable on the sheave, and has both ends connected via linkages to an eccentrically mounted bell crank on an auxiliary sheave. One cable end, after passing around the drive sheave, engages a portion of the auxiliary sheave circumference, translating the auxiliary sheave eccentrically and pulling both ends of the bandlike member when the cable is loaded.
