Abstract: The invention relates to thermally stable, weather-resistant polyamide moulding compositions containing as stabiliser, a mixture of a copper halide, one or more halogen compounds and hypophosphorous acid or an alkali metal or alkaline earth metal salt of this acid, wherein the individual components of the stabiliser mixture are added in an amount such that the molar amount of halogen contained in the moulding composition is greater than or equal to six times the molar amount of and less than or equal to fifteen times the molar amount of copper contained in the moulding composition and the molar amount of phosphorus is greater than or equal to the molar amount of and less than or equal to ten times the molar amount of copper contained in the moulding composition.

Abstract: A cable terminal or joint connection for making electrically conductive connection of a multi-core cable to an electrical device or to another multi-core cable, including a cable terminal component having a union nut and a wire receiving and guide part and including a device terminal component having a clamping and terminal unit which is provided with insulation piercing connecting devices and with terminal elements, and having a sleeve-shaped terminal body which is provided with an outside thread corresponding to the inside thread of the union nut. When the wire receiving and guide part is assembled with the union nut, the wire receiving and guide part is axially fixed via at least one slotted elastic locking ring in the union nut and the wire receiving and guide part is able to turn while in the axially fixed position relative to the union nut. Additionally, loss of the locking ring prior to assembly is prevented by fabricating the locking ring in one piece with the wire receiving and guide part.

Abstract: Bioresorbable pin systems useful for the reduction of bone fragments and for fixing bioresorbable membranes to a bone are provided, particularly pins having a detachable handle and a pre-fabricated hole in the handle through which a tether may be threaded to facilitate removal of the handle once it has been detached from the pin.

Abstract: A cable connector includes a housing which supports terminal contacts which have insulation piercing devices. An insulating part can be inserted coaxially into the housing and the housing includes recesses which receive the insulation piercing devices of the terminal contacts. A union nut which can be threaded onto the housing drives the insulating part and serves to fasten and seal the entire cable connector.

Abstract: The present invention is concerned with a process for the production of high molecular weight thermoplastic ppolycarbonates having improved flame resistance and in conjunction with glass fibres, improved mechanical properties and the polycarbonates so produced. A solution polycarbonate is reacted with an alkali metal salt soluble in the melt of the polycarbonate until the Staudinger Index has increased by about 3 to 30 cm.sup.3 /g. This usually requires about 0.0001 to 0.1 wt. % of the salt, based on the weight of polycarbonate and a temperature of about 250.degree. to 400.degree. C for between about 1 and 30 minutes. In a preferred embodiment the reaction is conducted in a self-cleaning twin screw extruder.
