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 invention relates to a water turbine that extracts the rotational energy out of a vortical flow of water. The water turbine includes a rotor with at least one channel extending circumferentially and longitudinally across the rotor. The channel includes a bend to extract the rotational energy from the vortical flow of water. The invention may also include guide vanes at an inlet of the water turbine to cause a vortical flow in the water turbine. Furthermore, the water turbine may be tapered between the inlet and the rotor to increase the rotational velocity of the vortical flow.

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.
