IPC: H04J3/14
Filed: 1982-07-07
Abstract: Verfahren zur Prüfung von Analog-Digital-Wandlern und/oder von Digital-Analog-Wandlern oder von nachrichtentechnischen Übertragungsabschnitten, die solche Wandler enthalten oder mit ihnen in Reihe geschaltet sind, für digitale Nachrichtengeräte, insbesondere zur Prüfung von Codecs für PCM-Geräte, sowie Vorrichtung zur Durchführung des Verfahrens. Der Prüfling wird mit einem analogen vorzugsweise sinusförmigen periodischen Meßsignal bzw. mit digitalen Abtastproben eines solchen Meßsignals beaufschlagt, wobei zwischen der Periodendauer des Meßsignals und der systemeigenen Abtastperiode ein solches Zahlenverhältnis besteht, daß alle innerhalb eines vorbestimmten Prüfzeitraumes liegenden Abtastzeitpunkte unterschiedliche relative Zeitlagen in dem Periodizitätsintervall des Meßsignals innehaben. Dadurch entsteht eine Vielzahl von Ausgangsinformationen des Prüflings, die in ihrer Gesamtheit die Antwort des Prüflings auf das Meßsignal beliebig genau beschreiben. Diese Ausgangsinformationen werden gegebenenfalls nach Analog-Digital-Wandlung in einem Normkodierer, in einem Speicher abgelegt und stehen zur Ermittlung der gesuchten Eigenschaften des Prüflings, z.B. der pegelabhangigen Verzerrungen, mittels eines Rechners zur Verfügung.

Title: Process for the preparation of 1,2-dichloroethane
Inventor: HUNDECK JOACHIM DR
IPC: C07C17/38
Filed: 1982-09-01
Abstract: 1. Process for making and purifying 1,2-dichloroethane by reacting ethylene and chlorine in a reaction zone having a liquid medium containing chlorinated C2 -hydrocarbons circulated therein, at a temperature lower than the evaporation temperature of said medium under the pressure prevailing inside the reaction zone, in the presence of a customary chlorination-inducing catalyst and optionally an inhibitor reducing the formation of by-products, with the resultant formation of crude 1,2-dichloroethane, removing the crude dichloroethane from the reaction zone and purifying it in a separate fractionating zone placed downstream thereof, which comprises : a) introducing approximately equimolar proportions of ethylene and chlorine into the circulated liquid medium ; intensively mixing the whole in a mixing zone and then reacting the mixture in a reaction zone at a temperature of about 75-200 degrees C under a pressure of about 1-15 bars, the mean sojourn time of the reaction mixture in the mixing and reaction zone being about 1-15 hours ; b) removing a portion of the liquid reaction mixture from the reaction zone and subdividing said portion into two partial streams, of which one is passed through a heat exchanger to give off calorific energy, and recycled at lower temperature to the mixing and reaction zone ; whilst the second partial stream is introduced into an expansion vessel in which a quantity adequate to the reaction product formed in the reaction zone and optionally also a proportion of 1,2-dichloroethane originating from a third source and introduced into the reaction zone is evaporated from said second partial stream ; resulting vaporous matter is introduced into a fractionating column whilst unevaporated liquid matter of the second partial stream is recycled into the mixing and reaction zone of the circulated liquid medium ; and c) separating distillatively 1,2-dichloroethane from the vaporous matter introduced into the fractionating column with the use of a portion of the heat energy transferred inside the heat exchanger and removing the 1,2-dichloroethane overhead, higher chlorinated products being obtained in the column base portion from which they are removed and worked up separately.

Abstract: Wegen der seit Jahren weltweit anhaltenden Inflationstendenz und der erheblichen Zunahme der Geschäfte über Waren- und Dienstleistungsautomaten, ist ein Bedarf an höherwertigen Münzen entstanden. Die Münzbehörden erwägen, hierfür auf kleinere Münzstücke überzugehen und diese von den vorhandenen höchstwertigen Münzen der jeweiligen Systeme durch eine andere Münzfarbe zu unterscheiden. Hierfür eignen sich insbesondere Goldfarbtöne. Es besteht somit ein Bedarf an einem goldfarbenen Werksoff, der sich einerseits durch Giessen, Walzen und Prägen gut zu Münzen verarbeiten lässt und der andererseits den ursprünglich vorhandenen goldenen Farbton möglichst lange behält, d.h. der eine hohe Anlaufbeständigkeit aufweist. Zur Lösung dieser Aufgabe wird vorgeschlagen, als Werkstoff zur Herstellung von Münzen oder dergleichen eine Kupfer-Basis-Legierung mit 4 bis 6% Nickel, 4 bis 6% Aluminium, Rest Kupfer, zu verwenden, die vorzugsweise noch 0,5 bis 1,8% Eisen und/oder 0,3 bis 1,5% Mangan enthält.

Abstract: A technique for processing pictorial information to enable its display on a desired display device independent of the latter's resolution characteristics includes a unique encoding procedure and a corresponding decoding and display procedure. Attributes of each element of a picture or image (such as its color) are specified by a group of N bits. The bits are assembled to form M-bit active portions of a series of bytes. M and N need not be integrally related. Ones of the words also define the size of the elements with respect to a unit display space (the horizontal and vertical dimensions of each element can be different), the order in which the elements are arranged in the picture (e.g., left to right or vice versa) and the value of N. The bytes are decoded and the picture displayed by locating each pel in the unit screen coordinate space, mapping each location to a corresponding storage location in an array formed by a frame memory, writing the attributes of each pel in one or more of the storage locations, and sequentially reading the contents of the memory and applying the output to the display device.

Abstract: Alkylidene diesters such as ethylidene diacetate are selectively produced in high yields by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound, a halogen component, a palladium cocatalyst and a promoter component which is an agent for liberation of carboxylic acid anions. The process is carried out in the liquid phase in a solvent comprising a carboxylic acid at a temperature in the range of 150 to 190 DEG C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/cm<2> and a carbon monoxide/hydrogen mole ratio of 6:1 to 1:2 for the ester reaction and 10:1 to 1:2 for the ether reaction. When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process or the production of vinyl acetate which produces acetic acid rather than consumes it.

Abstract: A current-discrimination arrangement, in particular for use in stabilizing circuits comprises two cross-coupled transistors (T 1 , T 2 ). The current (I) to be discriminated is applied in parallel to both transistors (T 1 , T 2 ). For small currents both transistors (T 1 , T 2 ) conduct to the same extent, whilst at a current     in which R is the resistance value of the collector load impedances (1, 2) of the two transistors (T 1 , T 2 ), the circuit becomes bistable. The steep characteristic at the transition (T 1 , T 2 ) from non-stable to the bistable operation is used as discrimination characteristic.
