Abstract: Connection of two longitudinal sections (10, 22) that are at an angle to each other, each longitudinal section (10, 22) having two connecting sides (12) and two wall sides (14), where at least one connecting side (12) of each section (10, 22) exhibits a groove (24) that is undercut on both sides and on both sides of the undercut groove (24) an integral longitudinal flange (30). The first longitudinal section (10) exhibits a transversely cut section face, the end face (16) of the first longitudinal section (10) which is secured at an angle to a connecting side (12) of the second longitudinal section (22). The first longitudinal section (10) exhibits a recess (18) at its end (16) in which a connecting element (60), introduced into the groove-like recess (34) between the longitudinal flanges (30) in the second longitudinal section (22), engages--as a result of which the connecting element (60) forms a mechanical joint by virtue of fit with the end recess (10).

Abstract: Ultra-fine-grained thermoplastics such as polyolefins, for example, having an average particle size D.sub.50 of less than 400 .mu.m and are present in a mixture along with a filler where the amount of filler material in the mixture amounts to 40 to 90% with respect to the mixture. As such ultra-fine-grained thermoplastics cannot be obtained by means of the normal milling process of if so then only with considerable expenditure, the process for manufacturing ultra-fine-grained thermoplastics is performed in such a manner that a mixture containing 10 to 60 wt. % thermoplastics with respect to the mixture and 40 to 90 wt. % filler material with respect to the mixture is ground e.g. in an impact pulverizer, as a result of which thermoplastic particles with an average particle size D.sub.50 less than 400 .mu.m are produced.

Abstract: In a construction featuring sections of light metal and light-weight composite panels joined to the sections the composite panels feature a plastic core with light weight metal outer sheets bonded to both sides. The outer sheets partially overlap a light metal connecting section which is integrally incorporated in the composite panel and interlock by virtue of fit with that section. The connecting section features connecting strips that lie as pairs on corresponding connecting strips on the section. At least one of the connecting strips is riveted to this neighboring strip. The connecting strip of the connecting section is inclined at an angle with respect to a contact plane in order to create pressure on the neighboring connecting strip, and is joined at its free edge by laser welding to the neighboring connecting strip.

Abstract: Process for manufacturing blister packs, for example to accommodate items such as pharmaceutical items in the form of capsules, coated capsules, ampoules etc., from a base part and a lid part made from strip shaped packaging material. The base part exhibits permanently shaped recesses which are surrounded by shoulders and the lid part exhibits permanently shaped recesses which are surrounded by shoulders; the base and lid parts lie on a plane of symmetry and the base and lid parts are joined at their shoulders over the whole or part of the surface area in the region of the plane of symmetry; the recesses in the base and lid parts which are symmetrically arranged with respect to the plane of symmetry form compartments and the contents are contained in the compartments. The blister packs may be manufactured, for example, by folding or turning over an endless strip of packaging material along a line of symmetry.

The trailing arms are extruded single or multi-chamber hollow sections, made for example of aluminum or one of its alloys. The trailing arms feature a projection facing the middle of the vehicle. The projections on the trailing arm form a channel-shaped section along with the wall strip of the trailing arm. Attachment structure for attaching the elements for wheel suspension and for the crossmember of the axle or axle carrier or swinging axle link may be mounted on this channel-shaped section.

Projecting out of the inner-lying face of the profiled strip and directed at the base is at least one projection and/or an additional element which are/is embedded in the base. Each additional element may delimit an undercut space which is filled in an interlocking manner by metallic material of the base.

Abstract: Multilayer film material (22) for manufacturing a pipe-shaped body (21) of tube (17). The film material (22) contains at least one barrier layer (10). The film material (22) is of thickness (d) extending form the outside (14) of the pipe-shaped body (21) to the inside of the same. At least one barrier layer (10) is arranged within a distance (a) of the inside (15) of the pipe-shaped body (21). The distance (a) represents 5 to 40% of the total thickness (d) representing 100 percent. The film material used on a tube exhibits therefore a barrier layer which lies close to the inside of the tube and hence also close to the contents of the tube. Volatile constituents of the tube contents beings able to penetrate essentially only to the barrier layer and are not able to become concentrated in the other, thick layers of the wall.

Abstract: Pouches of flexible packaging material exhibit a tearing zone in the form of a weakness such as perforations or a separation in the material, this in order to be able to remove the contents easily. The packaging material is covered over by at least one film-forming mass, at least in the region of weakness, in order that the package remains closed until the contents are to be used. The film-forming mass may be the decorative printing on the pouch. After packaging, the contents are protected by the pouch and, in order to remove the contents, the pouch may be opened readily by a pulling or snapping movement which causes the covering of film-forming mass to break.
