Abstract

955,188. Automatic control systems. INDUSTRIAL NUCLEONICS CORPORATION. Jan. 1,1962 [Jan. 27, 1961],No. 65/62. Heading G3R. The quantity per unit length of a compressible material leaving a continuous processing plant is maintained constant by adjustment of the density of the material being fed to the plant by applying a variable suction whilst keeping the cross-section and feed rate constant. As shown, the plant produces a cigarette rod 41 which is continuously checked by a radiation gauge 24, 25, the output of which controls the degree of vacuum inside a grooved pick-up wheel 33. The bottom of the groove is perforated, a stationary screen being positioned to blank the perforations where the tobacco is required to leave the wheel. At this point a knife 37, rotating a fixed distance above the groove, removes excess tobacco which is returned to the main stream 32, while the corrected stream 38 proceeds to a rod forming and wrapping device 39. Specifications 887,267, 887,271 and 955,189 are referred to.
