Patent DE-3916817-A1 (DE)
Title: Joining two pref. metal sheets stacked on die using stamp - by driving material from top sheet into torn regions of bottom sheet created by downward action of stamp
Inventor: THUMM GUENTER DIPL ING
IPC: B21D39/03
Filed: 1989-05-23
Abstract: Means for joining at least two parts, esp. made of sheet metal, uses a stamp (3) and a die (4) with the novelty that the front end of the stamp has a flattened surface (10) which forms a tear (8) in one of the parts (2) that are to be joined. The flattened region (10) is narrower than the width of the stamp's stem and the transition region (11) between them is conical in shape. The die is flat at least in or around the region of the tear. The jointing action causes material (9) from the bottom sheet (2) to be expelled down into the die (4) - Fig, 1. ADVANTAGE - Even or flat joint surfaces are readily produced with material for increasing the strength of the joint at least partly flowing into the torn region.

Title: Castor
Inventor: SCHULTE PETER
IPC: B60B33/02
Filed: 1989-05-27
Abstract: The invention relates to a castor with a fixing device for blocking the running mobility of the running wheel and/or the swivel mobility of the fork, in which the fixing device is formed as a two-armed, spring-actuated rocker lever, which is held within a fork-back extension arranged on the trailing side and can be actuated by means of a foot-actuated switching lever, which is arranged in a longitudinal slot on the fork-back extension and is formed as an expanding lever. In order to configure the castor of the type mentioned at the outset such that it is simpler and less expensive, and to make it possible for the running-wheel braking to be adjusted, it is provided according to the invention that the rocker lever be designed as a leaf spring and be held on the vertical pivot by a central tongue, via a coaxial pin, as well as by angled edge portions and beads protruding on the fork limbs. Furthermore, a brake screw is installed in the rocker lever as a braking surface for the running wheel, which brake screw can be adjusted through a hole in the fork-back extension by means of its key end.

Title: Carrier strip for non-adhesive objects - has adhesive region near edges allowing objects to be stripped off from centre
Inventor: SCHREINER HELMUT
IPC: C09J7/20
Filed: 1990-08-10
Abstract: A carrier strip has a carrier film (1) with self-adhesive and non-adhesive regions (2). The non-adhesive regions can consist of a null layer which ifies the adhesive properties of the self-adhesive surface  e.g. a cover film made from polyester. Pref. the top surface of a carrier strip is coated with an adhesive and the centre region (2) is covered with a polyester film, leaving the edges (1am1b) (1a,1b) exposed. The carrier conveys labels (3)-which are coated with hot melt adhesive for later use and are therefore non-adhesive at room temp.  The labels are attached to the carrier only in the edge regions (3a,3b) and can easily be stripped off by bending the carrier strip over a sharp corner when the leading edge (3c) lifts off. USE/ADVANTAGE - The method allows carrier film to be used for articles which are not semi-adhesive but non-adhesive, flat and possibly flexible objects.
