Abstract: An energy-saving streamlining structure for the fronts of motor trucks, motor homes, buses and the like, comprises when deployed a forward-pointing transparent conical shell supported on the front of a truck by a stem generally axial to the shell; telescoping and rotary linkages of the stem fold the shell into damage resistant horizontal opposed-segment or bow-tie storage-configuration compactly retracted against the front of the vehicle. Transparent panels provide driver-view of the highway through the unit, anti-shake spring biasing stabilizes the mechanism when deployed, and power drive provides for remote control operation from the truck cab at all times. Compactness and integration of the parts adapt the unit for after-market attachment and capability for transfer from one vehicle to another as well as for installation as original equipment at the factory; in an embodiment provision is made for the invention when deployed to return to storage mode when the vehicle reduces speed to a predetermined rate.

Abstract: A lighter-extinguisher for cigarettes and the like which permits smokers to enjoy smoking with reduced possibility of annoying non-smokers, reduced waste of smoking materials, and with no staining of fingers or scattering of ashes. A cigarette-package-sized device with a cigarette mouthpiece end projecting from it in position for smoking is held in the smoker's hand at all times during smoking of the cigarette; between puffs the cigarette is extinguished by closing a valve to shut off air from the burning end held inside the device, and is conveniently relit when a puff is desired by opening the valve, which automatically actuates the lighter. An ash pit receives ashes down a slide and the lighter mechanism follows the tip, assuring ready re-ignition.
