Abstract: The invention relates to a profiled plastic section (1) for a metal/plastic composite profiled section (31). The profiled plastic section (1) comprises a first profiled element (2) and at least one second profiled element (3). The first profiled element (2) and the second profiled element (3) together form a latching mechanism (4, 9; 5, 10; 6, 11), by means of which a form-fitting connection can preferably be produced between the first profiled element (2) and the second profiled element (3) in a width direction (x) and in a height direction (y). The first profiled element (2) and the second profiled element (3) overlap preferably over a large area when the form-fitting connection is produced between the first profiled element (2) and the second profiled element (3), and the form-fitting connection can be produced on the cross-sectional plane (x, y) between the first profiled element (2) and the second profiled element (3) by latching the profiled elements (2, 3) of the profiled plastic section (1).

Abstract: A method for producing insulating profiles comprises manufacturing a profile body and a first functional element separately, and the profile body and the first functional element are supplied to an ultrasonic welding device, wherein the profile body and the functional element are connected to one another by a material bond by formation of a welded joint. The profile body and the functional element are brought together into a predetermined first cross-sectional geometry during formation of the welded joint and are thereafter guided in this cross-sectional geometry until the plastics material of the welded joint solidifies to such an extent that the profile body and the first functional element are fixed in the predetermined cross-sectional geometry.

Abstract: A spacer for insulating glass panes comprises a profile body made using a first plastics material, which has a substantially U-shaped cross section with first and second side walls arranged in parallel, each having a free end and an inner wall extending between the first and the second side wall, and a vapor diffusion barrier made of a poorly heat conducting material, extending from the free end of the first side wall to the free end of the second side wall, wherein the vapor diffusion barrier is arranged substantially in parallel to and spaced apart from the inner wall. The profile body together with the vapor diffusion barrier encloses a cavity of the spacer which is optionally configured to accommodate a desiccant.

Abstract: A spacer for insulating glass panes has a profile body having a cross section having first and second side walls, an inner wall and an outer wall, forming a closed hollow profile, wherein first and second filamentary reinforcing elements are arranged in the inner wall, the first primary reinforcing element being arranged in a first portion of the cross section in which the inner wall adjoins the first side wall, and the second reinforcing element being arranged in a second portion of the cross section in which the inner wall adjoins the second side wall, the first and second primary reinforcing elements being arranged, as regards their cross sectional surfaces, at most approximately 50% in the first and/or in the second side wall, and such that spacing between the centroids of the cross sectional surfaces of these reinforcing elements is approximately 40% or more of spacing between the side walls.

Abstract: A motion nut for a lifting device, especially a car jack, in which a basic body has an internal thread and a threaded spindle is seated in the internal thread. The basic body together with the internal thread is a single unit component formed of at least two separate material components of different materials. The two separate material components form an internal thread region part and an external part, so that properties of the internal thread region is selectable different from properties of the external part. The properties of the thread being selectable for reduced friction and the properties of the external part being selectable for increased strength and stiffness.

Abstract: In a process of making a rotationally symmetrical article, such as rope pulleys, running wheels or the like, from plastic material such as cast polyamides, raw material melts of plastic material and predetermined amounts of catalysts, activators and stabilizers are prepared at different formulation and composition to impart the melts with different mechanical strengths after polymerization. The raw material melts are poured into a heated, rotating mold in succession in dependence on a polymerization pattern of the raw material melts. After complete polymerization of the melts, the mold is opened, and the finished article can be removed from the mold for optional refinishing procedure.

Abstract: A composite section for frames of windows, doors, facade elements and the like consists of two metal section parts and at least one plastic insulating web which joins these metal section parts and is held with its ends in corresponding grooves of the metal section parts. The plastic material forming the insulating web is combined with a composite fiber skeleton consisting of heat-resistant fibers. The composite fiber skeleton is anchored in a positively and/or frictionally connected manner in the grooves of the metal section parts so as to also ensure cohesion of the metal section parts when the plastic material of the insulating web degenerates. The composite fiber skeleton is at least one band with thickened edge sections which are anchored in a positively connected manner in the grooves of the metal section parts.
