Title: Plastics welding system - with electric current passing through conductive plastic wire with metal powder admixture
Inventor: BOLDT WILFRIED
IPC: B29B13/02
Filed: 1978-11-29
Abstract: Thermoplastic materials can be welded together by laying into the seam a plastic wire which has been made conductive by an admixture of metal chips or metal powder. The electric current flowing in it when a voltage is applied to its ends causes the plastic material to melt and to fuse together. d.c or a.c. of any frequency can be applied. the same effect can be achieved by metallising the surface of an intended weld so that a current can flow. When either of these systems is applied to dielectric welding, a cocn. of the electric field lines to the seam is attained. Systems saves energy by locally concentrated heating leads to faster welding rates and is easy to apply.

Title: Furniture drawer central closing rod - has stop elements swinging into blocking position when one drawer is opened
Inventor: NICKEL KLAUS
IPC: E05B65/465
Filed: 1979-08-16
Abstract: The closing edge moves into engagement with faces of closing lugs on drawers, when a closing rod is swung about a vertical axis. The system is used in provision for centrally closing pull-out drawers, or similar, in furniture. The closing rod (1) bears one or more blocking elements (3) allotted to the drawer. When a drawer is opened, this acts in conjunction with a forward-facing carrier edge on the drawer's sidewall, in swivelling from a release position. The blocking elements for other drawers are swung into a stop position by coming into contact with a blocking edge on the drawers sidewall. This obviates any danger of the desk or other piece of furniture from tilting forwards with too many drawers open.
