Abstract: PCT No. PCT/EP79/00098 Sec. 371 Date Jun. 10, 1980 Sec. 102(e) Date Jun. 10, 1980 PCT Filed Dec. 11, 1979 PCT Pub. No. WO80/01149 PCT Pub. Date Jun. 12, 1980. In an apparatus for the biaxial, simultaneous stretching of a flat film web from particularly polypropylene, the edges of the film web 1 are engaged by grippers 3, which in the stretching zone 9 are driven by divergent threaded spindles 5, and at least part of the stretching in longitudinal direction is effected, by means of a progressive pitch of the threaded spindles, simultaneously with part of the transverse stretching. Subsequent to the progressive pitch a thread with degressive pitch is provided, preferably at the end of the threaded spindles, effecting shrinkage of the previously stretched film web in longitudinal-direction, while preferably simultaneously the film web is further stretched in transverse direction. The shrinking of the film web takes place over about 5 to 10% of the spindle length at up to 10% of the previously produced longitudinal stretching, to the longitudinal stretching degree desired in the finished film.

Abstract: An arrangement which provides an indication of the economy of motor vehicle operation includes a number of sensors for detecting different vehicle operating factors including engine speed, distances travelled by the vehicle, and the position of the engine throttle. An acceleration measuring device is coupled to the distance sensor to determine the vehicle acceleration. Circuitry coupled to the sensors including the acceleration measuring device provides operating condition values in the form of code word elements. This circuitry includes a first comparator for setting a first set of threshold values so that the code word elements provided by the first comparator each correspond to a certain engine speed range. The circuitry also includes a second comparator operative to set a second set of threshold values so that the code word elements provided by the second comparator each correspond to a certain acceleration range. Likewise, the third sensor operates to provide code word elements each of which corresponds to a particular range of positions of the engine throttle. A matrix combines all the code word elements into a combined code word which is then evaluated and accorded a particular rating. At least one signal transmitter is provided for alerting the vehicle operator when the rating of the combined code word is such as to call for a change of operating behavior, e.g., a shift of gears.
