Patent EP-0089458-A2 (EP)
Inventor: HOLZER HELMUT
IPC: F16J15/3224
Filed: 1983-01-22
Abstract: A radial shaft seal ring has a lip ring for sealing to a shaft for rotation therewith. A U-shaped recess extends around the lip ring. An extension portion of a reinforcing ring which delimits a space on one side thereof to be sealed contacts the U-shaped recess without pressure or connection for low wear relative rotation therein. Preferably, the shoulder of the lip ring defining the side of the U-shaped recess on the sealed-space side of the reinforcing ring has a greater outside diameter than that on the other side to centrifugally aid the seal. More preferably, the latter is done by angling the U-shaped channel to the sealed side to also accommodate axial vibration of the shaft and lip ring.

Abstract: Die Erfindung betrifft ein Verfahren zum Herstellen von aus Trennkörpern mit Abschlußplatten bestehenden Trenndüsenelementen zur Trennung gas- oder dampfförmiger Gemische, bei dem aus durch energiereiche Strahlung in ihren Eigenschaften veränderbaren Formmaterial-Schichten durch partielles Bestrahlen und partielles Entfernen von Formmaterial unter Ausnutzung der durch die Bestrahlung erzeugten unterschiedlichen Materialeigenschaften die Negative der Trennstrukturen enthaltende Formen hergestellt werden, die mit einem mit dem zu trennenden Gemisch verträglichen Strukturmaterial aufgefüllt werden, wonach die Formen entfernt werden. Um ohne Verlust an raumlichem Auflösungsvermögen zur Herstellung der Trennkörper jeweils nur eine Schicht des Formmaterials verwenden zu mussen, wird erfindungsgemaß vorgeschlagen, daß die Dicke der Formmaterial-Schichten etwa gleich der vorgesehenen Dicke der Trennkorper und die Eindringtiefe der Strahlung kleiner als die Dicke der Formmaterial-Schichten gewählt werden und das partielle Bestrahlen und das partielle Entfernen von Formmaterial absweschelnd solange durchgeführt wird, bis die Negative der Trennstrukturen die Formmaterial-Schichten vollständig durchsetzen.

Abstract: 2- and/or 6-pyridylethylamino-substituted fluorans useful as color formers, particularly in pressure-sensitive carbonless duplicating systems and thermal-responsive marking systems are prepared by the interaction of (pyridylethylaminophe- nyl)carbonylbenzoic acids with 4-hydroxy- or alkoxyanilines or by the interaction of (disubstituted aminophenyl)carbonylben- zoic acids with N-pyridylethyl-4-hydroxy- or alkoxy acetanilides. The (pyridylethylaminophenyl)carbonylbenzoic acid intermediates required for the fluorans are prepared by interacting a N-pyridylethyl-3-hydroxyaniline with a substituted or unsubstituted phthalic anhydride. The N-pyridylethyl-4-hydroxy-or alkoxyanilines and the N-pyridylethyl-3-hydroxyanilines are prepared by interacting the respective aniline with a vinylpyridine.

Abstract: Die den Kern eines Reaktors bildenden Elemente umfassen in einem quadratischen Gitterverband regelmäßig angeordnete Stäbe (15), die von Abstandshaltern (1) umschlossen sind. Mehrere über die Länge eines Elements verteilte Abstandshalter (1) sind durch Strukturelemente (6) verbunden. Erfindungsgemäß bestehen einzelne Stäbe (15) am Rand des Kerns aus neutronenabschirmendem Material, das einen quadratischen Querschnitt aufweist. Im Gegensatz zu der üblichen zylindrischen Stabform erhält man eine bessere Abschirmwirkung gegenüber der aus dem Kern austretenden Neutronenstrahlung. Mit dem größeren Stabquerschnitt wird die Kühlmittelströmung axial kontinuierlich gedrosselt, so daß die gegenüber Brennstäben verringerte Aufheizung im Bereich des neutronenabsorbierenden Materials besser kompensiert wird.

Abstract: The sowing device has one or more sowing units, each comprising a seed dispensing device 22, 24, a leading trough-shaping device 54 and a trailing ground-equalising device 61 with a dispensing of seeds 40 onto the bottom 56 of the trough 52 formed by the trough-shaping device 54. A trough-bottom pressure element 58 is proposedly used for brushing the seeds 40 into the trough bottom 56. The seeds sown in this way germinate well because the seeds brushed in on the one hand are well exposed to light and on the other hand are thoroughly moistened, among other things as a result of the collecting effect of the trough formed in this way. <IMAGE>

Abstract: in the semiconductor memory device of the invention, a normal voltage detecting circuit (3) and a high voltage detecting circuit (9) are connected to a terminal (1) for the purpose of receiving a write enable signal. When a signal of normal level is supplied to the terminal (1), the circuit (3) controls data read or write with respect to a memory cell array (27) in accordance with the level of the write enable signal. An error correction code circuit (7) is rendered operative, and a soft error generated in data read from the memory cell array (27) is corrected. When a high voltage is applied to the terminal (1), the circuit (3) sets the memory device in the read mode. The circuit (9) detects application of the high voltage to the terminal (1) and supplies a predetermined signal to an ECC control circuit (11). In response to the signal, the ECC control circuit (11) stops the operation of the ECC circuit (7). Data without any correction of soft errors is output from the memory device, and testing of hard errors is simplified.
