Abstract: Method for controlling the speed of horizontally rotatable supply turntables for tape material. In such a method for controlling the speed by measurement on a moving tape, especially on a film tape (3) in cinema show operation by removal from the inside convolution (4) of a reel (2) resting horizontally thereupon, the lead-in angle in front of a lead-in point (6) fixed in location is contactlessly measured by reflection of infrared light on both sides of the film strip (5) fed in. In case of deviations of the measurement signal from a nominal value, the reel drive is corrected. A dual infrared LED with reflection light barriers (11, 12) arranged offset in angle and height and approximately focused on the lead-in point (6) is used.

Abstract: Pancreatin pellets are produced by a process employing extrusion techniques. In the process, a mixture of pancreatin powder and selected solvent is formed into a pliable mass suitable for extrusion. The extrusion is conducted followed by a cutting, shaping or forming of the extruded mass into pre-pellet like forms. Further drying and mechanical working of the pre-pellet forms results in the final pancreatin pellet of improved pharmaceutical and mechanical stability. A special aspect of the process is the selection of a solvent for mixing with pancreatin powder that is harmless to enzymes. Such solvents typically include isopropanol and acetone.
