Title: Air classifier
Inventor: FISCHER-HELWIG FRANK
IPC: B07B7/083
Filed: 1991-05-27
Abstract: In order to classify granular material into at least three fractions, previously bar basket classifiers with at least two classifier wheels have been used which are arranged in a housing spaced one on top of the other. The classifier wheels arranged one on top of the other were provided here with separate lines for feeding in the classifying air and conducting away the classifying air in order to avoid fine-grade material getting into the medium-grade material during classifying or medium-grade material getting into the coarse-grade material so that a high yield is accompanied by an exact separation of the respectively desired granular fractions from one another. On the other hand, a simplification of the classifier in terms of constructional design and in the operating mode is achieved according to the invention, accompanied by a high yield and exact separation of the respectively desired granular fractions from one another, by virtue of the fact that the classifier wheels (2, 3, 4) are concentrically nested in one another in the housing (1) and arranged at a distance from one another in such a way that the classifying air flows through them successively and that each classifier wheel is assigned a separate material discharge. …<IMAGE>…

Abstract: In enlarge dissolvers, for example, the sugar and sugar dust (2) carried by the transfer air is to be bound as intensively and hence as rapidly as possible by the liquid (23). It should be possible to work without a cyclone separator and without filters. For this purpose, the solid bulk material to be dissolved, for example sugar, is fed directly to the outlet region (11) of the circulation line (6, 6', 6'') of the circulating liquid before the latter strikes the impingement plate (5). The solid bulk material, for example sugar, is, with highly turbulent flow of the liquid, intensively mixed with the latter in the outlet section (11), and is partially dissolved, and the stream issuing from an outlet nozzle (4) of the outlet section (11) strikes the impingement plate (5). The transfer air is split by the latter into a multiplicity of small air bubbles which, rising slowly in the liquid (23), permit rapid binding of the sugar dust to the liquid. <IMAGE>

Abstract: The invention relates to a method and a device for dedusting and/or classifying granular and/or fibrous material in an airstream. For the purpose of exactly determining the sifting limit it is proposed that the material for sifting be introduced into an upper opening of a gravity chute (3) which has an open chute base (4). In addition to the material (1) for sifting, air is drawn in through the upper (entry) opening (2) of the gravity chute (3) and taken up in the tangential area of a drum-shaped airstream (air eddy stream 17, 21, 21', 21'', 21''') rotating in eddies. The material for sifting and air are exposed to the interplay of forces of the centrifugal and friction force of the airstream which is also carried along, in which case as a result of the centrifugal force of the air eddy stream the coarse-grade material is separated off and discharged through the open chute base (14). Above the rotating air eddy stream (17, 21, 21', 21'', 21'''), a portion of the airstream is branched off and guided out of the gravity chute (3) together with the fine-grade material carried in it. <IMAGE>

Abstract: An apparatus for detecting concealed explosive or narcotic substances using an ion mobility spectrometer (IMS) to analyze trace samples of those substances obtained by collecting adhering particles of dust from surfaces adjacent containers which may contain those concealed substances or from clothing of people that may be carrying them. The dust particles are capable, over a period of time, of adsorbing vapours emitted by concealed explosive or narcotic material in a container. Plastic explosives have very low vapour pressures but may, through mechanical abrasion and handling, distribute solid microscopic particles of that material around. The dust particles and microscopic particles can be collected by an air stream with an inertial collector and deposited onto a collecting medium, which is on a moveable surface, is then moved to another position adjacent the entrance to an ion mobility spectrometer where there are means to heat the particles to a temperature which will vaporize materials from the particles into the ion mobility spectrometer. That movable surface is provided with a number of collecting mediums for the particles so that as one is moved adjacent to the spectrometer, another collecting medium is moved beneath the base of the collector allowing collection and desorption to take place simultaneously.

Abstract: An apparatus and method for resin transfer molding composite articles of complex configuration that have high fiber-to-resin ratios. The molding apparatus includes a compliant mold subassembly comprising one or more conformable cauls and a complementary, non-permeable membrane that function, in combination, as a semi-rigid molding tool. The compliant mold subassembly is relatively insensitive to bulk variations of layed-up fiber reinforcement material, facilitating fiber reinforcement material lay up and closure of the molding apparatus. The compliant mold subassembly provides uniform pressures during various molding stages, i.e., resin injection, expulsion of excess resin, curing, to enhance the homogeneity and dimensional stability of the finished composite article. The semi-rigid aspect of the compliant mold subassembly facilitates demolding of the finished composite article. The process utilizes staged pressurization transmitted through the compliant mold subassembly to enhance resin flow for complete, uniform saturation of fiber reinforcement layups and to expel excess resin prior to curing of the resin impregnated fiber reinforcement layups.

Abstract: A removable optical disk of the write once type is managed to minimise size of the control area for user data recorded on the disk. Instead of recording each recorded file indicating token (serial number) as each file is recorded, a maximum value file token having a numerical value greater than a previous maximum value token is recorded in the control area such that any optical recorder receiving the disk may start recording data using such maximum value token. If the file indicating token values reach the maximum value token, then a new maximum value token is created. A pseudo end of volume (EOV) value is maintained which points to a one of the addressable data-storing areas of the disk which is allocated and not recorded as EOV. All allocated data-storing areas with addresses greater than EOV are recorded in contiguously addressed data-storing areas. When any data-storing area having an address higher than EOV is left unrecorded, then EOV is updated to point to that unrecorded allocated data-storing area. When either the maximum value token or EOV are changed or updated, both the EOV and maximum value token are recorded in the control area. Operations in a closed environment, super or umbrella allocation sizes and reduced EOV values are also disclosed.
