Title: Production of a tobacco filler for cigarettes cigars or the like
IPC: A24C5/18
Filed: 1961-11-16
Abstract: 1, 013, 492. Automatic control of tobacco. K. KÍRBER. Nov. 16, 1961 [Nov. 17, 1960], No. 41029/61. Heading G3R. [Also in Division A2] In a machine for producing a wrapped tobacco rod 10 employing a fixed trimming device 4 to remove the excess tobacco from a stream carried by suction in a grooved wheel 3, the stream is compressed in advance of the trimmer by a roller 6 whose pressure is varied in accordance with the output of an unspecified measuring device 11 situated anywhere after (or alternatively, before) the trimmer.. The compression by the roller is supplemented by the suction, which may also be varied when the roller reaches the limits of its travel. It is stated that, alternatively, the roller pressure may be varied only after the limits of suction variation have been reached. The position of the roller 6, which is rotated at the speed of the tobacco stream and may be spring loaded, is adjusted by a cam 14 controlled by a device 13 which comprises a reversible, single speed, electric motor. This motor is energized in one direction or the other according to whether the output of the measuring device 11 is above or below a predetermined datum. The control device 13 incorporates slipping clutches (Figs. 13,14,15 not shown) so that, when the cam 14 reaches its limits, a cord pulley is rotated, the cord operating a valve in the suction pipe connected to the wheel 3 (Figs. 6, 7 not shown). When this pulley, in turn, reaches its limit in either direction, a switch is actuated which operates an indicator or shuts down the machine. The roller 6 may have projections on its periphery (Fig. 3, not shown) for compacting the ends of cigarettes, and a rotating brush 17, (Fig. 2 not shown) may be placed in advance of the roller to remove gross inequalities in the tobacco stream. The excess removed by the trimmer 4 is carried by a wheel 5 from which it is removed by a spiked roller 5b and returned to the main stream on belt 2. Specifications 940,156, 985, 988, 1, 013, 493 and 1, 013, 494 are referred to.

Abstract: 914,669. Measuring electrically. WESER A.G. Dec. 4, 1959 [Dec. 4, 1958], No. 41342/59. Class 40 (1). [Also in Group XIX] Thrust in a rotary shaft 2 mounted in a thrust bearing 1 on a base-plate 3 is ascertained indirectly by arranging one or more measuring devices between the plate and a supporting surface to measure the forces exerted therebetween, such forces being proportional to the thrust forces of the shaft against the bearing. As shown, two pressure-measuring cells 5, which may be hydraulic or electrical, are interposed between the plate 3 and a supporting surface 4, the respective indications given by the cells being proportional to the positive and negative axial thrust in the shaft. The cells may be let into the plate or the support. In another embodiment four cells are disposed respectively at the corners of the base-plate and this arrangement is said to allow the friction torque set up by the rotation of the shaft to be disregarded. Cells may also be provided above as well as below the base-plate. In a further embodiment the base-plate 3 is bolted directly to the surface 4 and strain gauges are applied to the fixing bolts to indicate the forces therein.

Patent GB-437433-A (GB)
Abstract: 437,433. Calculating-apparatus. SEEHASE, H., 1, Elsenstrasse, Berlin. May 20, 1935, No. 14674. [Class 106 (i)] A stylus-operated adding and subtracting device has sliders with saw-like teeth 22, 23 on one side and square teeth 25 on the other. The sliders are mounted in a casing provided with operating slots 12 and reading apertures 14, the sliders having projections 18 which engage guide slots in the back of the casing. The saw-like teeth are adjacent the operating slots 12 and when adding the sliders must be moved either up or down, depending on whether the total is greater or less than nine. The two sets of saw-like teeth slope in opposite directions and an attempt to move the slider in the wrong direction is ineffective, since, should the correct direction be, e.g. upwards, then the corresponding set of teeth will be adjacent the stylus when it is inserted. Transfer is effected by sliding the stylus into the ends 13 of the slots 12 to engage the square teeth of the next highest sliders. The numerals " one " ... " nine " are provided adjacent the slots 12 for setting purposes. The device is inverted for subtraction, and the setting numbers are formed as shown in Fig. 7, so that when they are turned through 180‹ each number appears to be that of its complement with respect to ten.
