A roller belt arrangement for a CATERPILLAR (endless track) vehicle has at least one pull resistant belt having a first surface and a second surface opposite the first surface. Drive members are connected to the first surface of the at least one pull resistant belt and extend transversely to a longitudinal extension of the at least one pull-resistant belt. The drive members have a U-shaped foot comprising a stay and two legs, wherein the stay rests on the first surface and the legs project perpendicularly from the first surface. The bolts, having a head and a threaded end opposite the head, are provided for connecting the drive members to the at least one pull-resistant belt. Plate members are non-rotatably positioned between the legs. The bolts penetrate the at least one belt, the stays, and the plate members, with the threaded ends positioned between the legs. Nuts, threaded onto the threaded ends of the bolts, are provided for securing the bolts and are nonrotatably secured relative to the plate members.

A water aerator is provided that has a rigid support plate that in the operating position is disposed essentially horizontally. The support plate has a practically planar upper surface and at least one aperture for air. An elastic plate of elastomeric material is disposed on the upper surface of the support plate. The elastic plate is provided with a plurality of fine slits that can be widened by air that is introduced between the support plate and the elastic plate. The elastic plate has a rim that sealingly surrounds the downwardly directed rim of the support plate to be secured thereto in a hook-type manner.

A method of producing a plastic pin, including a bowling pin, having a cellular and/or porous core that is surrounded by a solid-walled, noncellular and nonporous shell. The shell is initially produced as a whole body in a mold. While the material of the shell is not yet hardened and is still deformable, an insert is introduced into the narrowed neck portion of the shell, in a direction axial relative thereto, in such a way that the insert displaces an inner layer of the shell, dividing the hollow interior of the shell into an upper and a lower chamber and producing a fixed connection with the material of the shell. Material for the core, with such material being provided with an expanding agent, is then introduced into the shell, and after the shell and the core have set, the mold is removed.

An elastomeric stator for an eccentric spiral pump is provided. The stator has a lining that is made of elastomeric material and has a hollow chamber that serves for accommodating a rotor. The hollow chamber has a double or multiple spiral configuration. A rigid casing surrounds the lining and both the casing and the lining have an essentially uniform thickness over their length. The casing is spiraled in conformity with an inner contour of the hollow chamber. A respective flange ring is secured at each end of the casing for resting against other pump parts. The flange rings are detachably connected to other pump parts without the use of tie rods.

The invention relates to an apparatus for aerating water, with at least one diffuser element through which air is introduced into the water that is to be aerated. The diffuser element is connected with the distribution tube via a tubular connector. The distribution tube conveys the air, which is compressed for the aeration, and in particular has a quadrilateral cross-section.

A conveyor belt for a conveying device is movable in a longitudinal direction thereof on the conveying device and includes at least two pull-resistant, parallel belts extending in the longitudinal direction of the conveyor belt. Bending-resistant rods are connected perpendicularly to the at least two parallel belts so as to be spaced apart from one another. Follower members, including a base with an upper portion and a lower portion, are provided for entraining goods to be conveyed on the conveyor belt. The follower members are connected with the base to the rods such that the upper portion is positioned above the conveying plane of the rods and the lower portion is positioned below the conveying plane. The upper portion and the lower portion are connected to one another with an interlocking hook connection.

Power-operated closing devices, particularly electrically operated windows and sunroofs of motor vehicles, have two electrical conductors being spaced apart from each other for disengaging a switching process of a drive unit when brought into contact. For the purposes of simple manufacture and reliable contact-making, a trapping protector is provided, which includes a flexible hollow profile made of an elastomer or plastic material having a flat base area and a mounted arched profile area enclosing a hollow chamber. The base area and a zenith area of the arched profile area include conductive material and are separated from each other by insulating profile areas.

Stator for an eccentric single-rotor screw pump has a casing made of steel or the like and a helical elastomer lining. Stator and a method for its production are described which can also be made with larger lengths at low production costs. Stator is composed of at least two stator segments that are axially arranged in a line, whereby the stator segments are connected to one another at their abutment so as to be pressure-tight by a tube of a polymer material that is pulled onto the casing and overlaps the abutments and by a metal ring radially pressed onto it.
