20110098515 | METHOD OF PRODUCING NEOPENTYL GLYCOL - The present invention relates to a method of producing neopentyl glycol by addition of isobutyraldehyde and formaldehyde in the presence of a tertiary alkylamine as catalyst to give the hydroxypivalinaldehyde with subsequent liquid phase hydrogenation in the presence of a nickel catalyst at a temperature of 80 to 180° C. and at a pressure of 6 to 18 MPa in the presence of an aliphatic alcohol and in the presence of water. | 04-28-2011 |
20110184212 | PROCESS FOR PREPARING NEOPENTYL GLYCOL BY CRACKING HIGH BOILERS OCCURING IN THE PRODUCTION PROCESS - The present invention relates to a process for obtaining neopentyl glycol by hydrogenating cracking of high-boilers occurring in the production process in the presence of copper-chromite catalysts. The hydrogenating cracking proceeds in the absence of solvent at a temperature of 140 to 220° C. and at pressures of 7 to 28 MPa. | 07-28-2011 |

20110180372 | Transfer Device for Mail Items - A transfer device for mail items with a transfer unit which has an ejection point for transferring individualized mail items to an item carrier is provided. Further, the transfer device includes a transport device for transporting the mail items to the ejection point in a direction of transport. The transport device includes two belts for holding the mail items on both sides and for transporting the mail items and further has means for adapting a space between the belts to the thickness of a mail item. The means for adapting is a belt tilt means which is pivotal about an axis of rotation, the pivotal movement pivoting one of the belts and therefore a distance between the belts is variable. | 07-28-2011 |

20140236345 | SORTING INSTALLATION AND SORTING METHOD FOR JOINTLY SORTING DIFFERENT KINDS OF ARTICLES - A sorting installation and a sorting method jointly sort two kinds of flat mail items. For each article to be sorted, a value that a prescribed sorting feature assumes for the article is measured. The article is transported by a first transport device to a separating filter. An article of the first article kind is redirected in a first outward-transfer device. On the basis of the ascertained sorting feature value, one sorting output from a first set of sorting outputs is selected. The article is transferred outward to the selected sorting output from the first sorting output set. An article of the second article kind is redirected to a second transport device and transported to a second outward-transfer device. On the basis of the ascertained sorting feature value, one sorting output from a second set of sorting outputs is selected. | 08-21-2014 |
