Abstract: Process for providing a polypropylene composition comprising a branched polypropylene in which a polypropylene with a melt flow rate MFR2 (230° C.) of more than 1.0 g/10 min is reacted with a thermally decomposing free radical-forming agent and optionally with a bifunctionally unsaturated monomer obtaining thereby the branched polypropylene,wherein the polypropylene composition has a F30 melt strength of more than 5.8 cN and a v30 melt extensibility of more than 200 mm/s.

Abstract: Polypropylene composition comprising a polypropylene base resin whereby the polypropylene base resin has a MFR (2.16 kg, 230° C., ISO 1133) of 8 to 24 g/10 min and a LAOS-NLF>2.8 whereby LAOS?NLF=|G?1/G?3| where G?1—first order Fourier Coefficient, G?3—third order Fourier Coefficient.

Abstract: The present invention is concerned with a polypropylene composition comprising a polypropylene base resin, the polypropylene composition having —a XHU content of less than 1.25 wt.-%; —a F30 melt strength of at least 30 cN, determined in the Rheotens test at 200° C.; and —a melt extensibility v30 of at least 200 m/s, determined in the Rheotens test at 200° C. In another aspect the present invention is concerned with a polypropylene composition having an MFR (2.16 kg, 230° C., ISO 1133) of 1.0 to 5.0 g/10 min comprising a polypropylene base resin, the polypropylene base resin being obtainable by producing an intermediate polypropylene having an MFR (2.16 kg, 230° C., ISO 1133) of 0.5 to 2.5 g/10 min in the presence of an asymmetric catalyst; mixing the intermediate polypropylene with peroxide and at least one diene at a temperature of 20 to 90° C.

Abstract: A multistand press or similar press facility for the forming of sheet metal parts, is provided with bedplate, press stand and several press slides driven by the press drive for tool top parts interacting with tool bottom parts. Gearings for deflecting the rotating movement of the motor drive into the upward and downward movement of the press slides are arranged between press stands which each form a pair of stands, and are disposed opposite one another, and above the introduction of force into the press slides. Two gearings are provided for the respective pair of stands of two press slides. This make it possible to drive the press slides assigned to a pair of press stands from one press stand area.

Abstract: A throttle flap construction (12) is installed in an exhaust gas duct (11). For the installation the duct wall is provided with a radially facing, axially extending narrow slot (20) centrally provided with a circular opening so that a flap disk (14) may pass radially inwardly through the slot while a bearing portion (17) of the flap disk (14) may pass through the central circular opening. During installation, the flap disk (14) extends vertically when the throttle unit is inserted, a cover (16) is bolted to a flange (11A) surrounding the slot (20) and the central opening (21). Thus, the duct (11) can be properly sealed without cutting entirely through the duct in a radial plane.

Abstract: For avoiding collisions between the grippers (5) adapted to be moved out of the idling stage area and the grippers (4) disposed fixedly at interchangeable gripper rail partial sections (1) and work tool parts, the grippers (5) which are adapted to be moved out of the idling stage area, are raised into an upright position. The grippers (5) and the rotary adjusting drive (10) for the uprighting are adapted to be moved out of the idling stage area on a carriage (18-gripper mounting support) by way of an adjusting means (13) at the exchangeable gripper rail partial section.

Abstract: An intermediate storage in a press in which intermediate storages are to be provided within the area of idling stages thereof. The intermediate storages include storage templates matched to the shape of the bottom side of the workpieces which are adapted to be liftable in the vertical direction by way of lifting means. The lifting means may thereby act on the storage templates in the sense of a lifting movement, for example, by way of intermediate members displaceable by a motor-driven spindle, which act on the storage templates in the sense of a lifting movement by way of counter-abutment surfaces disposed at the ends of the storage templates.
