    摘要: A cylinder housing (1) is cast with a cylinder wall (2) in the making of a cylinder for an internal combustion engine. The cylinder wall delimits an interior space (3) for accommodating a reciprocating piston and, thereafter, a control window (5) is machined into the cylinder wall (2) as an opening of a transfer channel (4) into the interior space (3). A two-stage machining for forming the control window (5) is provided in order to make possible a rapid and cost effective manufacture of the cylinder. In a first step with a work tool (7) having a rotating primary movement (11), a breakthrough (10) is machined into the cylinder wall (2) and, in a second step with a work tool, the breakthrough (10) is widened to the wanted dimensions of the control window (5).

    摘要: Process for the preparation of an aromatic polyether in the presence of finely divided condensation auxiliaries.The process for the preparation of an aromatic polyether by condensation of the reactants in the presence of carbonates of metals of Group I of the Periodic Table, as condensation auxiliaries, employs the metal carbonates sodium carbonate or sodium bicarbonate or mixtures thereof in the form of very finely ground salts.The fine particle size distribution of the carbonate allows a significant shortening of the reaction times and permits polyethers having a defined degree of condensation to be reproducibly prepared.
