Patent EP-0037149-A1 (EP)
Inventor: DE GRAAF THEODORUS FRANCISCUS
IPC: C07C45/00
Filed: 1981-03-25
Abstract: An improved process for the dehydrogenation of alcohols, to produce aldehydes therefrom, using a copper-containing catalyst, is described wherein the alcohol is introduced in the gas phase initially in admixture with an inert gas only, and after an initial reaction period the alcohol is continued to be introduced, in the gas phase, in an admixture with an inert gas together with a minor amount of hydrogen. As a result, prolonged catalyst activity with retained selectivity is achieved.

Abstract: The invention relates to a process and apparatus for the manufacture of fibers from attenuable materials, such as glass making materials, by centrifugation. In a process in which the attenuable material is directed onto the peripheral surface of a centrifugation wheel which is enveloped by a gas current produced by a blowing crown, the invention comprises the projecting onto the fibers of a liquid composition from a centrifugation element, the projection being carried out close to the wheel in the form of drops which penetrate and are atomized by the gas current. The apparatus of the invention includes a projection element rotating with the centrifugation wheel for centrifugal delivery of the drops of liquid composition. The invention provides a very uniform treatment of the fibers, particularly by means of liquid binder compositions.

Abstract: Two pairs of plane-parallel glass plates (3-6) provided on both sides with a dielectic antireflection coating (8) which pairs are arranged sequentially in the beam path mutually rotated by 90<o> about the direction of radiation. The plates are arranged so that their angle can be adjusted with respect to the direction of radiation (9), a kinematic coupling of the plates one to another ensuring that the angles of inclination of all the plates are always the same in magnitude. However, within a pair the plates are in each case symmetrical with respect to a plane normal to the direction of radiation. The attenuation of the system depends on the angle of inclination of the plates and is a minimum when the light is incident vertically. The attenuation system does not cause any beam offset, and also has the particular advantage, inter alia, that it does not alter the polarisation state of the light beam and is thus suitable for both unpolarised and polarised light. <IMAGE>
