Inventor: ENGELBART WILKE
IPC: A01K61/00
Filed: 1988-02-11
Abstract: PCT No. PCT/DE87/00273 Sec. 371 Date Feb. 6, 1989 Sec. 102(e) Date Feb. 6, 1989 PCT Filed Jun. 12, 1987 PCT Pub. No. WO87/07590 PCT Pub. Date Dec. 17, 1987.In a method and a device for the widespread fine-bubble aeration of liquids, resilient, perforated membranes, which are preferably in the form of aeration hoses, are arranged in a liquid receptacle and are maintained horizontal by means of holding and guiding devices and are stretched, relative to their rest states, preferably by means of tensioning devices. Because of the stretching, the passage of the gas is improved and a uniform, finely dispersed gas bubble formation is produced. For clearing the perforated membranes of blockages of the perforations, the streteched state of the membranes is briefly released and subsequently again reproduced. For strong impurities, the gas supply is interrupted, the membranes are exhausted of gas and water, the stretched state is subsequently released and, after a predetermined time, gas is again fed into the perforated membranes and then the stretched state is reproduced.

Abstract: The invention relates to a process for the continuous preparation of acetates by a transesterification reaction in the homogeneous liquid phase in the presence of a catalyst selected from metallic alcoholates. The process comprises more particularly the introduction of the catalyst into a reactor (R) and the introduction of the reagents, formed by an acetate (I) and an alcohol (II), into a distillation column (D1) surmounting the reactor (R) and operating at a pressure (P1) identical with that in (R). The acetate (III) formed is withdrawn from (R) mixed with the catalyst, which is separated and recycled in (R). An azeotropic mixture (M1), comprising the acetate (I) and the alcohol (IV) formed, emergences at the head of (D1) and feeds a distillation column (D2) at a pressure (P2) lower than (P1), so as to produce at the head of the column an azeotropic mixture (M2) depleted in alcohol (IV), the mixture being recycled in (D1). The process permits the use of relatively humid reagents and alcohols of low reactivity, more particularly secondary alcohols.

Abstract: A hinged sliding door for passenger-conveying vehicles, in particular rail vehicles, whose door leaf (1) can be slid in its longitudinal direction on a guide element (3), the guide element being swivellable transversely to the plane of the door leaf by means of cranks (4, 5) with vertical crankshafts (8, 9). The cranks (4, 5) form, together with this guide element (3) and the door frame (17), a four-bar linkage with opposing cranks. As a result, it is achieved that the door leaf (1) assumes a highly inclined position when the guide element (3) swivels, by means of which position the leading edge of the door leaf is lifted out of the door opening. The cranks (4, 5) are expediently of the same length. In order to coordinate the sliding and swivel movement, the door leaf is guided at its upper and lower end by guide rails (10).

Abstract: Oleaginous substances such as vegetable oil, baby oil, olive oil, margarine, lanolin, cocoa butter and the like have their affinity for water altered by mixing the oleaginous substance with sugar and melt spinning the mixture in a cotton candy spinning machine or the equivalent. As so modified the product disperses autogenously in water forming a colloidal or colloidal-like dispersion. The modification enables such widely disparate procedures as incorporating shortening oil in a cake mix containing flour but no egg, producing a confection or medicated lozenge by dehydrating the dispersion and allowing the melted residue to solidify.

Title: Optical fiber coating control
Inventor: FRAZEE RALPH E JR
IPC: G03B7/087
Filed: 1990-03-28
Granted: 1995-02-28
Abstract: In accordance with the invention, the functions of two TV cameras in the prior art for monitoring polymer coating concentricity and/or carbon coating thickness are accomplished by a single TV camera. Rather than being projected onto an opaque dispersive screen, the forward-scattered mode pattern of each of the orthogonal beams is transmitted through a translucent screen and reflected to an image combining device which transmits both patterns to the single TV camera. The two beams are slightly vertically displaced to establish displaced images of the two patterns. This allows the two patterns to be viewed simultaneously and distinguished by the TV camera. Modified electronics provide for alternate TV scanning of the two images so that a computer can monitor and correct concentricity and/or carbon coating thickness in real time during fiber production.
