Title: Toy hang glider kite for tethered or free flight - has triangular foil cover pierced at rear ends by strengthened ribs held in fitments fastened to top side of cover
Inventor: SCHENK FRANZ
IPC: A63H27/00
Filed: 1978-04-11
Abstract: The kite comprises a longitudinal bar (12, 14) and two splay ribs (16, 18) which extend for most of their length beneath the triangular foil covering (30). The ribs pierce this covering near the rear ends where they are then held in end fitments (26, 28) which are fastened to the top side of the cover (30). This increases the stability since the splay ribs (16, 18) are strengthened around the point where they bear on the longitudinal bar partic. as the ribs have at their inner ends a cross-sectional area which is twice the size of that over the rest of their length. This design also ensures the foil cover is not impeded by the ribs during flight since the wind pressure arches the cover accordingly.

Title: Fitting polyurethane rubber sheath over vehicle coil spring - by gripping with clamping claws, axially fixing tube and rolling over with compressing mandrel
Inventor: KOEHN HANS
IPC: B29C57/12
Filed: 1978-09-06
Abstract: The end of the tube is gripped whilst maintaining its 'natural' cross-section and preventing any axial movement. Its end is then shaped so as to form a relatively sharp edge; and finally pressure is applied axially so that the edge section of the tube is forced into the gripped part. For gripping the tube suitably shaped clamping jaws are used. Opposite a first frontal face of one of them there is an adjustably spaced block with wedge-shaped take-up through which a mobile mandrel moves axially. This mandrel is flat and has a transverse bore for rolling-over the edge-shaped end of the tube. The tube is fitted in a water- and dirt-proof manner after it has been slipped over the coil spring.
