Patent EP-0015006-A2 (EP)
Inventor: SOMMER KLAUS DR DIPL-CHEM
IPC: B01J19/00
Filed: 1980-02-22
Abstract: A process and apparatus for condensing solid materials such as phosphates which tend to sinter and adhere when heated in a reactor wherein the reactants are introduced into a trough-like reactor provided with at least one set of rotatable agitating paddles. Heat is supplied to the reactor by passing a heating medium, such as a molten salt or a molten metal, through one or more heating jackets on the exterior of the reactor housing. The agitating paddles press the solid material in a thin layer against the wall of the reactor housing, and the material in the layer absorbs heat from the heating medium and sinters to a hard layer. One paddle of each set of paddles is provided with a stripping knife which moves along a path closely adjacent to the exterior wall of the reaction chamber to strip sintered material from the wall of the reactor housing. Heat is also transferred to the interior of the reactor housing by circulating the peeled material through the interior region of the reactor housing.

Abstract: in a method and apparatus for producing ideographic texts, such as those utilizing Chinese characters, a twelve-key keyboard (10) permits construction of a shape identifier code utilizing indicia which represent the shape of a character to be reproduced. Preferably, the four corners of the character are utilized to effect the coding. Alternatively, a phonetic identifier code utilizing a phonetic alphabet can be constructed to represent the character. The identifier code is used to select from a memory file (32) all the characters corresponding to the keyed-in identifier code. If the word to be typed comprises a single character, means are provided for manually resolving ambiguities in the characters selected by the identifier code. If the word consists of two characters, means are provided automatically to resolve ambiguities in the word in accordance with permissible character pairings. If more than one possible pairing exists, additional means are provided for manually resolving ambiguities in the pairs. Means are provided for storing and/or displaying the unique character or character pair which results from the selection process, whereby text material in symbolic language characters may be rapidly and accurately produced. The text material thus produced may be used to control the operation of a printing device (44).

Abstract: A method and apparatus for separating serum from other blood components in a centrifuge tube. The separator comprises a cylindrical, laterally-expandable filter element (10) composed of a multiplicity of generally longitudinally-oriented fibers, 10 to40 millimicrons in diameter, formed of a biologically inert polymeric material having a specific gravity within the range of about 1.10 to 1.50 and bonded to adjacent fibers only at spaced-apart junctures. The filter element (10) has a diameter within the range of 9 to 15 millimeters, a length from 75 to 125 percent of its diameter, and a bulk density of about 0.20 to 0.60 grams per cubic centimeter. During centrifugation, the filter advances downwardly (arrow 21) from the mouth of the centrifuge tube (12), swelling laterally (arrows24) as serum (20) flows through the fine passageways running generally lengthwise of the filter, and causing the descending filter to wipe against the walls of the tube, pushing loose cells and fibrin (20b) ahead of it, and finally compacting and restraining thefibrin-cell ctot at the bottom (12a) of the tube to permit subsequent decantation of the filtered serum (20a). In one embodiment, the filter is introduced into the tube by means of a stretchable cap (11) which serves as a carrier for the filter prior to insertion and as a protective cover for the tube thereafter.

Abstract: A harmony generator for an electronic organ and a method of generating harmony in an electronic organ are disclosed. The identity of played keys of the keyboard(s) is read into a storage device (58). The data contained in this storage device is then operated upon by a data processing device such as a microcomputer (50), so as to supplement the played note data with additional data designating "fill-in" notes which are to be sounded in addition to those actually played, based upon specified criteria. The data contained in the storage device, as supplemented, is then used to control the transmission of tone generator signals to the audio output system (170) of the organ. In a preferred embodiment of the invention, the criteria used to select fill-in notes cause notes corresponding to the nomenclatures of played notes of the accompaniment keyboard to be sounded as though played in the octave belowthe lowest note played on the solo keyboard. Other fill-in criteria are also contemplated. The invention is particularly suited to use in conjunction with an 8-bit or a 12-bit microprocessor. In the 12-bit embodiment, the 12-bit words which are used to manipulate the data into the storage device each correspond to a single octave of the keyboard. In the 8-bit embodiments, two words are necessary in order to specify each octave of data. The fill-in notes are generated by combining played accompaniment data with masks. The identity of these masks is based upon the nomenclature of the lowest played note of the solo keyboard. Depending on the available space in the memory of the microcomputer, these masks can be looked up in a table, or generated by a suitable algorithm. Fill-in notes can be generated simultaneously by more than one set of criteria, and the fill-in notes so produced can be separately voiced.

Abstract: A vibration isolation system includes a seismic restraint assembly (28) that attenuates forces above a chosen magnitude transmitted to a unit (20, 22) from a support (26) during a seismic event. Vertical friction elements (96) on a vertical frame (34) engage and support a vertical damper element (90). Horizontal friction elements (142, 144) on a horizontal frame (32) engage and retain a horizontal damper element (124). One frame (128) is connected to the unit, the other (130) to the support. The vertical and horizontal damper elements interconnect, but lost motion spacing between these elements ordinarily prevents low level vibrations being communicated therethrough. Each of the vertical and horizontal friction elements is spring biased by springs (104,158) into a predetermined frictional engagement with its associated damper element. The force of the engagement is adjustable to adjust the level at which higher than ordinary forces that are being transmitted through the assembly will begin to be attenuated by slippage of the frictionally engaged elements.

Abstract: The invention relates to an apparatus for testing the filling level of cigarette ends which are tested individually or in blocks. Corresponding reflective light barriers (11) serve to irradiate the cigarette ends and receive the light reflected therefrom, in order to generate  a signal corresponding to the degree of filling which is compared with a target value in order to sort out rejects. In order to achieve results with minimum expenditure and to eliminate distortions of the result caused by fluctuating distance between light receiver and cigarette end, a translucent plate (12) is arranged in front of the reflective light barriers (11), its outside being arranged in a manner such that the cigarette ends to be tested, when in contact with the plate (12), are situated at a distance in the region of the falling part (Kab) of the curve (K) of the luminosity of the reflected light plotted against the distance (d) of the cigarette end from the light receiver. In this apparatus, the simplest reflective light barriers (11), consisting of a light-emitting diode and a phototransistor, can be used. <IMAGE>

Abstract: An improved circuit for performing high speed arithmetic computations is described, and includes a mechanism for dynamically deleting faulty data bits in a configuration for minimizing propagation delay paths. The invention is particularly applicable to an associative processor wherein the data word length and rate of flow of data may vary from one instruction to the next. In accordance with the invention, date propagation delay time is minimized as is the number of required circuit interconnections, thereby making the invention easily manufacturable on an LSI chip. The advantages of the circuit design are multiplied in an associative processor, since such processors are highly reconfigurable and must be able to exclude unwanted bits from an arithmetic operation, to change data word sizes and to delete failed bits. The present invention is advantageously implemented in arithmetic carry circuits and in cascaded multiplexer logic circuits, which may effectively be implemented in MOS (metal oxide semiconductor) integrated circuits, or in CMOS (complementary MOS) integrated circuits in which a plurality of stages of such circuits must be connected in series, i.e. eight, sixteen, thirty-two, etc., while still providing a rapid execution speed.
