Patent EP-0029933-A2 (EP)
Inventor: KORTE HANS DIETER DR
IPC: F28G9/00
Filed: 1980-11-07
Abstract: Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum periodischen Abreinigen der Rohre von Wärmeaustauschern von Ablagerungen feinteiliger Feststoffe, insbesondere Rußen oder pyrogen hergestellten anorganischen Oxiden. Die Vorrichtung besteht aus Strahldüsen, welche im Abstand über den Gaseintrittsöffnungen der Rohre angeordnet sind und über mit Absperrorganen versehene Leitungen mit einem gegenüber dem Prozeßgas Überdruck aufweisenden Reinigungsgas gespeist werden. Die Strahldüsen können stationär oder über eine Reihe der Wärmeaustauscherrohre hinweg verschiebbar angeordnet sein. Das Verfahren sieht vor, die abzureinigenden Rohre, vorzugsweise nacheinander während des Betriebs des Wärmeaustauschers periodisch mit einem schlagartig freigesetzten und kurzzeitig aufrechterhaltenen Gasstrahl hoher Geschwindigkeit zu spülen.

IPC: G06F3/06

Abstract: To provide for a more economic buffer capacity through facilitating high speed readback check of data transferred to a cyclic memory (16) from a free input buffer before the source data is lost, the cyclic memory is organized into a number of data blocks, each interleaved with or simultaneously accessible with the other data blocks. Thus, a long data record comprises several data blocks and therefore several cycles of the memory. A readback check of data transferred is accomplished by writing data into one check number generator (51) and one data block in a first cycle, writing data into another block on the second cycle while reading back the first data block to a second check number generator (52), continuing in this manner until the entire record is transferred, and reading the last block of written data into the check number generator (52). The two generated check numbers are then compared to detect any error and effect a retransfer if required before the source of the record is lost by overwriting.

Abstract: Um eine kostengünstige und raumsparende Speicherung und/oder eine zeitsparende Übertragung von Weißblöcke sowie Text-, Graphik- und/oder Graubildbereiche von Druckvorlagen repräsentierenden Daten zu erreichen, ist Voraussetzung, daß die genannten unterschiedlich strukturierten Druckvorlagenbereiche jeweils optimal binär zu codieren sind. Bei dem vorgeschlagenen Verfahren wird die Druckvorlage (D) opto-elektronisch durch ein Videosystem (V) abgetastet. Die gewonnenen Abtastwerte werden digitalisiert und abgespeichert. In mehreren Verfahrensschritten werden nacheinander horizontale una vertikale Weißblöcke in dem gespeicherten binären Abbild gesucht. Das durch horizontale Weißblöcke und das durch vertikale Weißblöcke unterteilte binare Abbild werden miteinander logisch verknüpft, um weiße "Rahmen" für die einzelnen Druckvorlagenbereiche zu finden. Derartig weiß umrahmte Druckvorlagenbereiche werden anschließend einer Merkmalsextraktion unterzogen, um jeweils die Art (Text, Graphik bzw. Graubild) des Druckvorlagenbereiches zu bestimmen.

Abstract: An apparatus for determining the shape of an object such as an exhaust pipe comprises a carriage (11) which carries a scanning unit (10) and is movable by a motor (22) along a base (12) having supports (17) for the object. The scanning unit comprises two laser units (37) the light beams of which are directed by rotating mirrors (42) towards two parabolic mirrors (35), the beams being reflected by the latter so as to traverse the object at right angles to one another and in a common plane at right angles to the movement of the carriage. The beams are interrupted by the object, and light-responsive means (38) detect such interruption to determine the shape of the object. In a modification, the apparatus has two or three rotating laser units (50).

Abstract: Interface apparatus (10) for allowing a first serial communicating device (12) to communicate with a second echoplex communicating device (14). A first microprocessor (20) coupled to the first device (12) converts serial data to a parallel format. The parallel formatted data is transferred to a second microprocessor (22) which is coupled to the second device (14). The second microprocessor (22) converts the parallel data from the first microprocessor (20) into echoplex data for transmission to the second device (14). When data is to be transferred from the second device (14) to the first device (12), the second microprocessor (22) converts the echoplex data to a parallel format. The parallel formatted data is transferred to the first microprocessor (20), for conversion into a serial form and transmission to the first device (12). If both the first (12) and second (14) devices wish to transmit at the same time, priority is awarded to the second (echoplex) device (14). The interface (10) operates asynchronously on real time basis, and is transparent.

A combustion chamber is formed in the piston substantially in the form of a spherical cavity gradually narrowing towards the opening of the cavity at the top surface of the piston An air intake mechanism swirls intake air supplied to the combustion chamber. A swirl injector injects a fuel spray substantially in the form of a hollow cone having a velocity component in a direction tangential of the central axis of the nozzle. The nozzle is offset from the central axis of the cavity and inclined with respect to the central axis of the cavity so that the fuel spray is injected in a forward direction of a swirl stream of intake air in the cavity
