Patent FR-2529285-A1 (FR)
Inventor: SIEFERT ROLAND
IPC: F16H25/20
Filed: 1983-06-15
Abstract: The invention proposes a screw mechanism with a threaded spindle (1) driven by a motor and with a travelling nut (4) which is assigned to the threaded spindle (1) and by which both axially parallel torques can be transmitted (by means of a collar (6)) and also torques acting in the circumferential direction can be transmitted (by means of a toothing (5)). In this arrangement, the kinematic connection between the threaded spindle (1) and the travelling nut (4) is, on the one hand, extremely low-friction and, on the other hand, the coupling torque (required for torque output) between the threaded spindle (1) and the travelling nut (4) is formed by means of a friction clutch arranged concentrically to the threaded spindle (1). This clutch essentially comprises a disc spring (11), which, with the interposition of a disc (13) preferably manufactured from a sliding bearing material, presses a disc-shaped driver (8) against the front face of a gear (3) formed integrally on the threaded spindle (1) and serving to drive the latter. The connection of travelling nut (4) and the friction clutch is effected by means of a guide web (9) which is formed on the driver (8) and which is surrounded in the manner of a fork by an arm (7) formed on the travelling nut (4). Suitable stops serve to delimit the rotary movement of the travelling nut (4) which occurs during the reversal in the direction of rotation of the driving motor.

Title: Process for the expansion of tobacco leaves and apparatus for carrying out this process.
Inventor: YOO KWANG KEUN
IPC: A24B3/18
Filed: 1984-03-14
Abstract: The subject of the invention is a process for the expansion of tobacco stalks which involves introducing them into a U-shaped expansion tube 1 with a high-pressure gas. The tube 1 is maintained at the temperature of a thermostatically controlled vessel 10, and it is connected to a distributor tube 7 coming from the tobacco source by way of a connecting tube 3, thus forming a completely hermetic tubular system; a high-pressure gas is ejected from a nozzle into the connecting tube 3, this gas being admitted into the U-shaped tube 1 by way of a Venturi tube A, with the result that the tobacco stalks are sucked into the expansion tube 1. This process makes it possible to treat the tobacco stalks without excessive noise.
