Abstract: The invention relates to a container closure made of plastic having a spout with a jacket for fastening the closure to a container and for drinking out of the container, and having a lower rim and a nozzle adjoining the jacket and surrounding a pouring opening, the spout having an internal thread formed on the inner face of the jacket for screwing onto the neck of the container. Furthermore, the closure has a closure cap which is connected to the spout and has on its inner side a sealing element for closing the pouring opening, and a hinge with which the closure cap can be pivoted relative to the spout from a closed position into an open position and vice versa. A plurality of thread turns are formed on the outer face of the jacket.

Abstract: A closure cap for closing the pouring opening of a container, has a cylindrical threaded part with an open edge and an inner thread to interact with an outer thread of a container neck of the container, a security ring held on a protrusion on the container neck, a plurality of security webs releasably connecting the security ring to the open edge, a first holding strip with a first end rigidly connected to an open edge of the threaded part and a second end rigidly connected to the security ring, and a second holding strip with a third end rigidly connected to an open edge of the threaded part and a fourth end rigidly connected to the security ring. The second end on the circular path of the security ring is in a substantially diametrically opposed manner to the fourth end before the threaded part is opened for the first time.

Abstract: A closure cap for closing the pouring opening of a container has a cylindrical threaded part with an open rim and an inner thread which can co-operate with an outer thread of a container neck of the container, a security ring which is designed to be held on a projection formed on the container neck, a plurality of security webs which releasably connect the security ring with the open rim, and a first retaining strip having a first and a second end, the first end being securely connected to the open rim of the threaded part and the second end being securely connected to the security ring.

Abstract: In the rotationally symmetrical screen for fiber suspensions with a series of straight profiled bars which extend the direction of the screen axis and form slot-shaped screen openings between them, and with several ring-shaped profiled bar supports lying in planes extending perpendicularly to the screen axis, each of the profiled bar supports having in its edge region adjacent to the inlet side of the screen a series of cutouts opening towards the inlet side of the screen for insertion of the profiled bars, with the shape of these cutouts corresponding to the configuration of the cross-sectional regions of the profiled bars held positively in these cutouts, in order to simplify insertion of the profiled bars into the cutouts of the profiled bar supports each profiled bar has for each profiled bar support a recess which decreases the width of this cross-sectional region of the profiled bar, and the recesses lie outside the profiled bar supports in the finished screen.

Abstract: An electric drive unit particularly adapted for actuating windshield wiper assemblies includes a motor having it's armature shaft carrying aportion having two oppositely pitched worm threads. Two worm gear wheels are disposed each on opposite sides of the threaded portion and in engagement therewith. The axes of rotation of the worm wheels are in parallel. Two spur wheels are each concentrically seated on a respective worm wheel. The spur wheels each engage a wheel having its axis of rotation located in a plane defined by the axes of rotation of the worm wheels. The toothed wheel is connected to a drive shaft.
