IPC: C07H15/04
Filed: 1992-04-24
Abstract: Aliphatic alcohols with up to 30 and especially with 6 to 18 carbon atoms are separated from a mixture of alkyl glycosides and alcohols which are unreacted during the production of these alkyl glycosides, by single or multi-stage distillation. The alcohols are distilled off by a drop film evaporator to impoverish the reaction mixture to residual alcohol contents of 5 wt % and under. The strip load of the drop film evaporator is set to at least 1.0 m<3>/m h, especially at least 1.8 m<3>/m h and preferably at least 3.0 m<3>/m h. It is possible to reduce the alcohol content of the product to any value between 0.1 and 5 wt % at acceptable overall cost. The process is simpler, more economical and more reliable than prior art processes.
Patent DE-4213908-A1 (DE)
Inventor: SATZGER WILHELM
IPC: G01B11/24
Filed: 1992-04-28
Abstract: The invention relates to a method for measuring the curved profiles of edges such as the trailing edges of engine blades. For this purpose, a laser beam (4) impinges directly on a surface region, which is to be measured, of the edge. The laser beam intensity over the cross-section of the laser beam is locally defined by a radiation intensity matrix (5) between a laser beam and the edge, and the radiation intensity values are varied (1). The laser beam intensity reflected by the surface region (7) to be measured is detected row by row in conjunction with different radiation intensity values along the curvature of the edge to be measured, and a curved profile is determined from these measured values via a computer program. The method is particularly suitable for measuring sharp edges such as knife edges, cutting tool edges or engine blade edges.
