Publication number: 20240092749Abstract: A process for the epoxidation of propene involves reacting propene with hydrogen peroxide, in the presence of a methanol solvent and a shaped titanium zeolite epoxidation catalyst in a fixed bed reactor. The process then involves recovering methanol from the reaction mixture, treatment of the recovered methanol by passing it through a bed of an acidic ion exchange resin, and recycling the treated methanol to the epoxidation reaction; as well as regeneration of the acidic ion exchange resin. Catalyst breakage can be reduced or avoided by washing the regenerated bed of an acidic ion exchange resin with methanol until the methanol exiting the resin bed has an apparent pH higher than 1.8, before methanol treated with the acidic ion exchange resin is recycled to the epoxidation reaction.Type: ApplicationFiled: January 26, 2022Publication date: March 21, 2024Applicants: Evonik Operations GmbH, thyssenkrupp Uhde GmbHInventors: Maik BERNHARD, Sören Götz, Marc Brendel, Johan Anton, Matthias Pascaly, Thomas Noll, Jürgen Schemel

Patent number: 8382106Abstract: A method and apparatus for separating at least two bridges, especially gripper bars, of a segmented transport system for printing materials, e.g. sheets of paper in a printing press, include a transport system having a segmented electric linear drive with first and second primary parts constructed as segmented long-stator. The drive has a plurality of secondary parts constructed as carriages. Each secondary part assigned to the first primary part and each secondary part assigned to the second primary part are coupled by a crossmember to form a movable bridge. Two bridges in the same segment are moved jointly. A first bridge, reaching into a further segment due to jointly controlled movement, is moved individually under closed-loop control and separated from a second bridge, for locating the two bridges in different segments during further movement. Electrical and mechanical collisions of the bridges or of the carriages can therefore be eliminated.Type: GrantFiled: July 6, 2009Date of Patent: February 26, 2013Assignee: Heidelberger Druckmaschinen AGInventor: Matthias Nöll

Patent number: 8375856Abstract: In a method for compensating an oscillation which has a frequency spectrum with a number of discrete frequency components in a printing press, at least one counter torque is introduced into the printing press in order to compensate for at least one discrete frequency component of the oscillation. A first group of one or more frequency components are compensated for by introducing one or more previously determined counter torques, and a second group of one or more frequency components is compensated for by introducing specific counter torques as a function of a measurement, carried out during the operation of the printing press, of at least one signal which contains at least the one or the plurality of frequency components.Type: GrantFiled: March 26, 2007Date of Patent: February 19, 2013Assignee: Heidelberger Druckmaschinen AGInventors: Bernhard Buck, Eric Knopf, Matthias Nöll, Stefan Schreiber, Malte Seidler, Detlef Strunk

Publication number: 20080289527Abstract: A device for correcting the lateral position of a printing substrate, preferably a sheet of paper, held by a gripper bar and conveyed in a transporting direction has a linear drive that includes a first primary part and a first secondary part configured as a first carriage and associated with the first primary part, and a second secondary part configured as a second carriage. The first carriage and the second carriage are arranged on the same side of the printing substrate in the lateral direction and—to correct the position of the printing substrate in the lateral direction—are movable relative to each other in the direction of transport. Such a device may be used for transporting printing substrates and for correcting the register position of printing substrates in machines for processing printing substrates, preferably printing presses or machines for the further processing of printed products.Type: ApplicationFiled: May 19, 2008Publication date: November 27, 2008Applicant: HEIDELBERGER DRUCKMASCHINEN AGInventors: Michael Pasuch, Bernd Hoffmann, Hendrik Frank, Matthias Noll

Patent number: 7453223Abstract: For the active compensation of oscillations in a machine which processes printing material, a signal which contains an oscillation of the machine or of a part of the machine is measured and at least one counter torque is introduced into the machine to reduce the oscillation. At least one measure for a ratio between the amplitude of the uncompensated oscillation and the amplitude of the counter torque necessary for complete compensation is compared with a threshold value. The counter torque is determined in a first functional relationship with the oscillation if the measure is greater than the threshold value, and the counter torque is determined in a second functional relationship with the oscillation, if the measure is smaller than the threshold value. In the machine, a regulating device is operated in a first or second operating mode in dependence on the measure of the ratio.Type: GrantFiled: January 25, 2007Date of Patent: November 18, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Bernhard Buck, Eric Knopf, Matthias Nöll, Malte Seidler, Detleff Strunk, Uwe Tessmann

Patent number: 7412927Abstract: A process provides for the safe operation of a printing machine. The printing machine has a first cylinder driven by a first motor, and a second cylinder driven by a second motor. The first cylinder accepts sheets of paper from the second cylinder or delivers them to the second cylinder by a gripper system. In the case of a deviation in the synchronized running between the cylinders, the gripper system is retracted at least in part far enough into the first cylinder that the possibility of a collision of the gripper system with the second cylinder is eliminated.Type: GrantFiled: June 22, 2005Date of Patent: August 19, 2008Assignee: Heidelberger Druckmaschinen AGInventors: Hendrik Frank, Karl-Heinz Helmstädter, Jochen Bechtler, Stefan Maier, Matthias Nöll

Patent number: 5600434Abstract: Craft (11) generally and in particular the transport aircraft (11) which are used for humanitarian purposes and for supplying crisis reaction forces over militarily unknown territory and which have comparatively little manoeuverability are particularly endangered by partisans who operate out of cover with modern portable guided missiles (12), against whose homing heads (13) the flares which were previously discharged from aircraft (11) no longer afford an effective defence. Therefore those and other potentially endangered craft (11) are provided with easily interchangeably and autarchically equipped containers (17) from which the defence beam (16) of a laser source (21) in accordance with pre-guidance by a warning sensor (10), are directed by way of the tracking optical system (19) of a target tracking system (20) on to the approaching guided missile (12) whose homing head (13) is already locked on to heat sources such as for example the engines of the craft (11) to be protected.Type: GrantFiled: January 30, 1995Date of Patent: February 4, 1997Assignee: Diehl GmbH & Co.Inventors: Berndt Warm, Detlev Wittmer, Matthias Noll
