Publication number: 20130180995Abstract: A gas cylinder has a circular-cylindrical shell which is closed on one end by a bung assembly having a connection hole extending along a longitudinal axis direction of the cylinder. The bung assembly has an auxiliary hole extending in a direction which is inclined with regard to a longitudinal axis direction of the cylinder. The connection hole is for introducing gas into and retrieving gas from said gas cylinder, while the auxiliary hole cooperates with a sensor device for measuring a parameter indicative of the filling level of the gas in the cylinder. The auxiliary hole extends in a direction intersecting the central longitudinal axis direction of the gas cylinder and may have an inclination such that the auxiliary hole extends in a direction perpendicular to the central longitudinal axis direction of the gas cylinder. The auxiliary hole may be a through hole or a blind hole.Type: ApplicationFiled: December 21, 2009Publication date: July 18, 2013Applicant: WIKA Alexander Wiegand SE & CO.

Publication number: 20070276170Abstract: The invention relates to a continuous process for preparing polyolefins having a bimodal or multimodal molar mass distribution in suspension in at least two reactors R1, R2.x, R3.y which are connected in series and in which different reaction conditions are set. In this process, the offgases A1, A2.x, A3.y, A4 and A5 leaving all the reactors connected in series are firstly collected, the collected offgases are then compressed in a compression stage 10, the compressed offgases are subsequently cooled and the cooled material is separated into a gaseous fraction and a liquid fraction. The separated fractions are then recirculated to the polymerization process at different points. The process of the invention allows the total conversion of the polymerization, based on monomer and comonomer used, to be increased to a surprising extent.Type: ApplicationFiled: January 25, 2005Publication date: November 29, 2007Applicant: Basell Polyolefine GmbHInventors: Joachim Berthold, Frank Alt, Kaspar Evertz, Peter Kolle
