Patent DE-3145561-A1 (DE)
Title: Head rest for motor vehicle seats
Inventor: BUTZ EUGEN OTTO
IPC: B60N2/48
Filed: 1981-11-17
Abstract: In a known internally adjustable motor vehicle head rest, the lower insertion area, located in the back rest, of the support rod is held in a locking sheath whose sheath head facing the head upholstery carrier bears a hairpin-shaped two-legged holding spring whose holding leg engages through the locking sheath in a slot and at the same time engages in a support rod-side locking notch. In order to assemble the device, the head rest is inserted with its two support rods from above into the back rest-side premounted locking sheaths in a snap-in engaging fashion. Rod right-angled bent portions of the support rods remain visible between the back rest and head upholstery carrier. A headrest is to be provided which permits a secure, and at the same time easily releasable back rest-side attachment for the carrier rod-side right-angled bent portions which are to be held in the back rest. The invention achieves this object in that the sheath head (33) forms a widened portion (34) on one side directed toward the outside away from a central longitudinal plane (shown by y) of the locking sheath (15), which widened portion holds the support rod-side right-angled bent portion (35) and at the same time holds a bushing-like extension (36) which encloses the support rod (14) and is detachably locked in the sheath head (33). Said extension is a component of a cover shutter (38) which surrounds the support rod (14) and holds the back rest cover (37) against the end face (F) of the sheath head (33). <IMAGE>

Title: Variable vaulting-horse set
Inventor: ABBING FRANZ
IPC: A63B5/12
Filed: 1981-11-17
Abstract: In summary, it may be said that the variable vaulting-horse set is a universal sporting appliance which offers many possibilities for exercise (no constraints are placed on the imagination), can in some cases take on the function of other sporting appliances (horizontal bars), and can also be used methodically very practically by changing the angle of inclination of the oblique surfaces. This applies particularly to gymnastics for kindergarten and primary school children, and for the handicapped; but there are also many possibilities for exercise for older children, adolescents and adults. Furthermore, it is much quicker and less laborious to attach the lightweight additional appliances (ladders or connecting rods or cross-bars) than, for example, to transport benches and set up horizontal or parallel bars. Lightweight construction, versatile range of exercises and opportunities for methodically practical use are features of the variable vaulting-horse set.

Title: Method and appliance for the processing of textile materials
Inventor: BILA-NATZMER RUEDIGER VON
IPC: D06C7/02
Filed: 1982-08-20
Abstract: The invention relates to a method for the processing of textile materials, the materials being subjected to heat treatment. Heat treatment is followed first by cutting out and then by sewing. Textile materials, after being cut out, can curl up in the region of the cut edges. This effect makes the subsequent sewing work difficult. To allow a simple and rapid further processing of the cut-out textile material, it is proposed to refrigerate the textile materials before heat treatment.

Title: Adjusting device for objects to be printed by the screen printing method
Inventor: PAANS HERBERT
IPC: B41F15/08
Filed: 1982-12-09
Abstract: The adjusting device (26) comprises a horizontal base (54) for an object (10) whose upper end face (14) and lower end face, resting on the base (54), are not precisely parallel. The base (54) can be lifted by means of a lifting drive (40) and rotated by means of a rotary drive (50) about a vertical central axis (A). Arranged above the base (54) and offset relative to the central axis (A) is at least one push button (82) which can be actuated when the object (10) is lifted, regardless of the position of the upper end face (14). The push button (82) is switched such that, when it has been actuated, it causes the rotary drive (50) to rotate through an angle depending on the position of the actuated push button (82). The dependence is fixed so that the inclination of the upper end face (14) of the object (10) maintains a direction which extends transversely to the longitudinal direction of the conveyor (20) and is consequently harmless when the upper end face (14) is subsequently printed by a screen printing device which has a doctor blade which can be moved back and forth in the longitudinal direction of the conveyor (20). <IMAGE>
Patent DE-3247441-A1 (DE)
Title: Process and device for producing bead cores for pneumatic tyres
Inventor: BLUM HEINRICH
IPC: B29D30/50
Filed: 1982-12-22
Abstract: The bead cores, wound from a plurality of wire layers, for vehicle pneumatic tyres are subjected to various processing operations, such as, for example, impregnation and winding with textiles, before installation in the tyre blank. An important operation in this is the covering with the profile strips of vulcanisable rubber which are necessary for the continuous incorporation in the rest of the layer structure of the tyres and which hitherto, however, have always caused a break in the work sequence and have made necessary laborious manual work. By contrast, the aim of the invention is the production of the core rings from the winding of the wire layers through to lay-up of the profile strips in a continuous operation without the necessity of manual intervention. This is achieved by introducing slit carrier rings on which the core rings are built up and on which they are passed through all the intended work stations.
