IPC: C02F3/08

Abstract: With contactor bodies formed of spirally wound up corrugated panels providing ducts in the region of the corrugation profiles which are alternately filled with waste water and air, there is a problem to completely fill the ducts and to provide a continuous flow through the ducts in a body of simple and rigid construction. In order to solve this problem, the corrugation profiles of at least one corrugated panel (3', 3'') are inclined at a predetermined angle relative to the axis (XX) of the contactor body. Thereby, the disadvantages of the known, mechanically unstable constructions comprising a tube bundle are avoided and an intensive flow of waste water and air within the ducts is achieved. Advantageously, the corrugation profiles of winding layers arranged radially above each other or axially beneath each other comprise different inclination angles (a', a''), especially angles which are opened contrary to each other.

Abstract: Dans de tels appareils, des outils qui après déconnexion de l'électromoteur ont un mouvement à vide, tels que des scies circulaires, des tondeuses de gazon et autres, constituent un danger pour l'opérateur.

Ladite prise avec le dispositif d'entraînement s'effectue en même temps que l'actionnement du levier d'interruption (21) de l'interrupteur du moteur. Dans une variante avantageuse, l'énergie électrique produite par le générateur est utilisée pour alimenter durant le mouvement à vide de l'outil un dispositif d'alerte électrique, tel qu'une lampe témoin (33)(30).

Abstract: To create an insertable elastic section for connecting contact pins into through-openings in a printed circuit board, an axially extending section of a post or pin is deformed to provide an axially extending U-shaped section. The pin is provided with a regular transverse section from which the U-shaped section is deformed. The original shape of the pin may be rectangular. The deformation is carried out in a pair of die parts. The axially extending U-shaped section is divided into a bight part or base with a pair of legs extending outwardly from the opposite sides of the base. The outside surfaces of the legs are shaped to provide linear contact with the surface of an opening through a printed circuit board with the contact being afforded at the opposite ends of the legs. Transition sections interconnect the legs to the base and are provided with a reduced wall thickness as compared to the legs for enhancing the elasticity of the legs. The elasticity of the U-shaped section accommodates the diameter differences in the openings through the printed circuit board.

Abstract: The invention foresees a device performing the tobacco tamping in contemporary phase with the boxing filling one. This determines a permanent pressure effect on the heap and consistently reduces its height in connection with the employ of a lower boxing (6). The device is fitted on the boxing outside and employs a motor reducer (16) with self-braking motor which drives a horizontal shaft (19) fitted with a pair of pinions (20, 21): these ones, by means of chains (22, 23) with a synchronic alternate motion, drive a pair of arms (26, 27) bearing a tamping fork (30). With an alternate motion from outside, through a slit (33), the fork penetrated razing into the boxing (6) and compresses the heap; it is then lifted again when getting out from the boxing: this avoids interferences with the descending tobacco.
