Inventor: KATO AKIFUMI
IPC: C08F10/00
Filed: 1981-09-21
Abstract: With conventional anchor agitators in gas phase polymerisation, powdery polymer tends to adhere to the inner wall of the polymerisation vessel and a vortex is formed at the central part of the fluidised bed zone of the vessel. These problems are overcome by an anchor agitator which has a rotatable shaft (1), at least two pairs of arms (2,2; 3,3') provided on said shaft in mutally crossing positions and a respective agitation blade (4,4'; 5,5') provided at the radially outer end portion of each arm, opposed pairs of blades extending substantially parallel to and being located substantially equidistant from the longitudinal axis (X) of said shaft (1); in which one pair of blades (4,4') is a pair of main blades located farther from the axis (x) of the rotatable shaft (1) than a pair of other, subsidiary, blades (5,5') and each of the main and subsidiary blades meet certain geometrical requirements. This anchor agitator can be used in a vessel for the gaseous phase polymerisation of olefins.

Abstract: A light pick-up device for transparency and/or opaque scanning in either a drum or flat bed scanning device consists of a hollow body, which exhibits a light entry opening for the modulated light coming from the master. The inside surface of the hollow body, which is designed as a light pick-up surface for the opto-electronic conversion of the scanning light into an image signal, consists of a multitude of sub-surfaces, whose surface normals are oriented in the direction of the incoming scanning light. The sub-surfaces are the light surfaces of either opto-electronic transducers or are the end faces of optical fibers whose other end faces are coupled to an opto-electronic transducer. Because the disruptive influence of scratches and shadow edges in the master is suppressed, a high efficiency and a good uniformity of the scanning are achieved with the light pick-up device.

Abstract: The process relates to the continuous extraction of oils, fats and phosphatides from oil fruits and oil seeds by treatment thereof with polar organic solvents such as hexane. The process is characterised by the combination of the following stages:   a) extraction is carried out in several stages with one stage, but not the first, being carried out at a miscella temperature below 50 DEG C;   (b) the moisture content of the dried seeds, which are particularly employed as flakes, is less than 10 % by weight on entry into the extraction;   (c) the atmosphere in the region of the extraction is made as oxygen-free as possible;   (d) the temperature at which the water is removed from the solvent for recycling thereof to the extraction is 50 DEG C or below. The extraction of soya flakes with hexane is described as example. This results in a considerable simplification of the refining of the oil and in an increased yield of lecithin.
