Abstract: 413,170. Rotary engines. JAGER, C., 39, Alte Frankfurterstrasse, Waldhof, Mannheim, Germany. Nov. 3, 1933, No. 30594. Convention date, Nov. 5, 1932. [Class 110 (ii).] A pump, engine, or meter is formed with two similar rotors c, d of approximately elliptical shape provided with teeth on their peripheries. The lengths of the radius vectors, describing the pitch circles, are extended beyond the lines defining true ellipses, between each major and minor half axis, so that the sum of each pair of vectors measured from the rotor axes to the point of contact y is equal to the distance between the axes. The rotor peripheries may be smooth and the shafts connected externally by elliptical gears. A major axis of each rotor passes through the centres of two teeth, and the minor axes through the centres of two gaps, or vice-versa.

Title: Method and apparatus for drying tobacco
IPC: A24B3/04
Filed: 1974-07-15
Abstract: 1476364 Drying tobacco HAUNI-WERKE KORBER & CO KG 15 July 1974 [14 July 1973] 31174/74 Heading F4G [Also in Division A2] A method of drying tobacco comprises the steps of supplying tobacco at a uniform rate, acting on the material during its conveyance through a first homogenization region by a first heated air or other gas current whose moisture content corresponds at least approximately to that of the tobacco supplied, so that the tobacco and gas are in hygroscopic equilibrium, drying the tobacco whilst it is conveyed through a drying region acting on the dried tobacco whilst it is conveyed through a second homogenization region by a second heated air or other gas current whose degree of moisture corresponds to the desired final moisture of the tobacco after drying, so that the tobacco and gas are in hygroscopic equilibrium, and discharging the dried and homogenized tobacco at a constant rate. In the apparatus shown a conveyor 8 supplies moist tobacco 7 to a conveyor weigher 12 which feeds it to a vibratory trough 11 where its moisture is monitored by a transducer 46. The tobacco then moves by way of a slide 20 to a vibratory trough 13 which passes through homogenization chambers 2, 4 and drying device 3 comprising chambers 26, 27, 28 connected by pipes 29, 30. A pipe 21 supplies moist air to the chamber 2 which passes through apertures 16 in the trough 13 for venting through a pipe 22. Heated air passes from pipe 31 into the chamber 26 and thence to chambers 27, 28 through pipes 29, 30 prior to venting through a pipe 32. Air conditioned to the moisture of the discharging tobacco by a transducer 71 enters the chamber 4 by a pipe 36 and is vented through a pipe 37. The signal from the transducer 46 passes to a control transmitter 53 and from thence to a comparator member 66 connected to a transducer 67 for controlling the temperature of the air in the heater 24 and to a transducer 56 for controlling the moisture content of the air via a comparator member 54 and an amplifier 57, controlling a motor 58 operating a pump 59 supplying moisture to an intake pipe 61 connected to the pipe 21. The comparator also controls a fresh air valve 62. A transducer 71 at the outlet of the trough 13 in conjunction with reference transmitters 75, 82, 97, control the predetermined final temperature and moisture for the chamber 4 and through a servo drive 76 controls a fresh air valve 77 in the heated air intake pipe 78.

[Class 28 (ii).] In a slicing-machine, the carriage is reciprocated by an oscillating handle lever pivoted to the base. As shown in Fig. 1, the carriage 13 is slidable on guide rails 11, 12 and is pivoted at 22 to a link 21 pivoted at 20 to a rocking arm 19<a>, 19<b> on a shaft 18 which carries a quadrant 30 for driving the knife 14. The part 19<b> of the rocker is connected by a link 25 to the lower end of the handle lever 28 which is so bent that, at the end of the slicing stroke, it does not extend beyond the machine base. The shaft 27 carries an arm 81 having a projecting pin 79 which engages recesses 80 in the machine base and thus limits the movements of the lever 28. The quadrant 30 meshes with a pinion 32 in which a one-way drive, preferably of the wedging-roller type, is incorporated. A sprocket wheel 33 on the shaft 32 is connected to a sprocket on the knife shaft by a chain 36. In the modification shown in Fig. 5, the lower end of the lever 28 is connected by a wire or band 90 to a drum 91 on the shaft 32. Oscillations of the drum shaft 32 are thus produced, and an arm 94 on the shaft pulls the chain or belt 92 backwards over the sprocket or pulley 93 on the knife shaft. The backward movement of the chain 92 is effected by a tension spring 95. The sprocket 93 includes a one-way drive. The lever 28 may be mounted on the rock shaft 18, and the link 25 dispensed with. The pusher, clamp and spring feed means described in Specification 408,176 may be used. The invention may be applied to machines having a power driven knife and to machines having a mechanical feed.
