Abstract: A device for coupling two containers comprising connecting branches having essentially circular cross section, with each of the connecting branches having a closing member at one end, which is essentially circular in cross section, for closing the end facing away from the container. When the two connecting branches are brought together, the two closing members are combined into a single member moved by a single actuator so that no clearance is required in each of the branches between the ends of the branch and the member. Each of the branches has annular edge seals, which, in an uncompressed condition, engage a circumferential edge of each of the closing members and are compressed when engaged with the edge seal of the adjacent branch member to release the respective closing member.

Abstract: A device for coupling two containers comprises a pair of connecting sleeves, each having closing flaps that can be moved from a closed position to an open position by a part-turn actuator, with the outer surfaces of each closing flap facing away from the container lying flush with the outer surface of the relevant connecting sleeve in the closed position and the closing flaps are each seated in an essentially circular seal. To prevent the accidental opening of the closing flaps, each of the connecting sleeves is provided with a radially-movable pin in the wall adjacent the seal, which pin can be pushed radially inward to produce a bulge in the seal which will hold the respective closing flap in its closed position and which pin can be radially moved outward to release the flap.

Abstract: A device for coupling two containers comprises connecting branches having essentially circular cross section with each of the connecting branches having a closing member at one end which is essentially circular in cross section for closing the end facing away from the container. When the two connecting branches are brought together, the two closing members are combined into a single member moved by a single actuator so that no clearance is required in each of the branches between the end of the branch and the member. Thus, problems with dirt and atmospheric impurities in a space between the closing member and the end of the connecting member are greatly reduced to prevent contamination of the contents of the container.

Abstract: In a flyer-type textile spinning machine, spinning elements, such as the flyers or the bobbins or both, are driven by plural drive motors affixed at spacings to the rail supporting the spinning elements, each drive motor directly driving synchronously at least one spinning element via a timing belt, with the remaining spinning elements being synchronously driven, in turn, from the directly driven spinning elements via a series of like timing belts.

Abstract: A rotation preventing apparatus presents rotation of the spindles of a textile machine due to the rotative forces applied by yarn tension during de-actuation of the drive motors of the spindles. The rotation preventing apparatus includes a reciprocable member supporting a plurality of brake shoe components adjacent the spindles and a commonly actuating assembly including pneumatic cylinder and piston members for reciprocably moving the reciprocable member between a position in which the brake shoe components brakingly contact the spindles and a position in which the brake shoe components are displaced from the spindles to permit normal rotation thereof. According to one aspect of the present invention, a contoured plate member is substituted for the brake shoe components. According to another aspect of the present invention, an expandable elastomeric member is supported adjacent the spindles and is selectively expandable to brake the rotation of the spindles.

Abstract: A spinning machine has an electric motor for rotating a bobbin-supporting spindle to build a package of yarn thereon and a funnel for guiding yarn onto the spindle. The spindle is rotatingly driven by an electric motor and the electric motors of the spindle and the funnel are commonly connected to a frequency control means which is, in turn, connected to an electrical power supply means. The torque of the funnel electric motor is a function of a characteristic of the funnel in accordance with the relationship that the funnel is rotated by its electric motor at a lower rate relative to the contemporaneous rate of rotation of the spindle. The apparatus can include a switch assembly selectively movable between leads for selectively connecting the funnel electric motor to the frequency control apparatus to operate the motor or to the electrical power supply means to brake the motor.

Abstract: A process and apparatus for repairing thread breakage occurring in an open-end spinning machine which includes a spinning rotor, a pair of draw rollers, a thread tension sensor and thread windup spindles. The end of the thread to be reattached to fibers located within the spinning rotor is guided back from the windup spindle in such a way as to bypass the drawoff rollers and avoid being pinched thereby. The thread is passed alongside one of the draw rollers, preferably on a specially configured conical surface which facilitates eventual reinsertion between the two draw rollers.The drive of the windup spindle is restarted by the tension sensor when it detects the reattachment of the end of the thread to the fibers in the spinning rotor as manifested by the increased tension in the thread. The increased tension pulls the thread between the drawoff rollers which transport it to the windup spindle at normal operating speed.

Abstract: An open-end spinning device includes a spinning rotor having an axis of rotation, a bottom face and a lateral sliding face conically widening toward the bottom face and intended for receiving fibers which have been fed into the spinning rotor. A fiber collecting groove is located between the bottom face and the sliding face. A blast air opening having an axis is disposed on a stationary part of the spinning device adjacent to an inner chamber of the spinning rotor for feeding air to blow fibers and foreign bodies from the fiber collecting groove. A shallow, concave curve defines an inwardly curved portion of the bottom surface of the spinning rotor between its axis of rotation and the fiber collecting groove. The axis of the blast air opening is directed toward the inwardly curved surface of said bottom.

Abstract: An open end spinning machine has individual spinning locations which include a spinning rotor, various drive rollers and conduits and drive shafts which are brought into tangential engagement with drive belts or the like. For this purpose, each spinning location is enclosed in a movable housing which can be displaced vertically on a column mounted on the machine by one end. A stop pin in the column cooperates with a rotating ring in the housing and provides therewith a bayonet-like engagement. The motion of the housing in the opposite direction is limited by the angled arm of a lost-motion slide connected to the housing which makes contact with the stop pin in the column. Easy removal without tools permits ready access to the machine space behind each housing.

Abstract: A spooling mechanism, for the spooling or winding of textile threads includes at least one spool having a circumferential surface, presses against a driven winding shaft or the like which is mounted on a pivoting spool holder which pivots during increasing spool diameter, further pivoting permits the lifting of the spool off from the winding shaft. A linear servomotor is provided with a working member which can be driven with respect to a guide member. The working member serves to displace temporarily the spool holder and itself is displaceable by the spool holder. A locking mechanism, which is preferably a clamping mechanism, is provided, making it possible for the working member to execute its working stroke relative to the guide member while carrying along the spool holder.
