Abstract: A metal detector and distance sensor for a motor vehicle. A departure of the motor vehicle from a correct path indicated by one or two metal lines covered with paint in the road is signaled. The metals lines are formed by projecting a jet of metal in the gaseous state at high speed onto the road surface. A covering of paint is then formed over the metal line on the road surface. A turbine supplied by an air compressor projects the jet of metal in the gaseous state from a vehicle or a trailer having a metal supply device and a painting device thereon. A display indicates the direction of departure from the correct path and the distance separating the motor vehicle from a preceding vehicle. Alarm signals can be emitted upon the departure.

Abstract: A cooking spit has an insulating handle carrying a rod with electrically heated end parts disposed about a central part about which an open-ended tubular sleeve is removably fitted. The central sleeve supports a fowl for internal cooking by heat conduction through the central part and external cooking by air circulation, and simultaneously prevents grease and juice from dripping on the heated rod. The spit may be integral with a lateral cover of a cooking enclosure, or can be used in a dish with removable cover.
