IPC: B21D28/00
Filed: 1979-01-16
Abstract: Bei hydraulischen Pressen wird ein ein Schnittwerkzeug (4a, 4b) tragender Hubkolben (2) durch einen beidseitig arbeitenden Preßzylinder angetrieben. Zum Steuern der Hubkolbenbewegung ist der Preßzylinder mit einer Servoventilsteuerung ausgestattet. Zur Dämpfung des sogenannten Schnittschlags beim Durchtritt des Werkzeugs durch das Werkstücks ist eine Dämpfungseinrichtung vorgesehen. Sie besitzt einen Weggeber (7) der den Hubkolbenverstellweg abtastet. Das Ausgangssignal des Weggebers wird als Ist-Größe auf einen elektrischen Regelkreis (6) gegeben; als Sollwert wird dem Regelkreis (6) ein einer vorgegebenen stetigen Funktion entsprechendes Signal während der Schnittbewegung des Werkzeugs zugeführt. Hierdurch folgt das Werkzeug einer vorgegebenen Weg-Zeit-Funktion, und der Durchtritt durch das Werkstück erfolgt mit relativ geringer Geschwindigkeit.

Abstract: Method and apparatus for rotating an information storage disc (11) about its central axis at a prescribed angular velocity that varies according to the radial position of an optical transducer (15) for recording information thereon, whereby a uniformly high density of information can be recorded over the entire disc. The apparatus includes a register (21) for storing a digital measure of the radius of the current track being recorded by the transducer (15), along with velocity signal circuitry for producing a disc velocity signal having a frequency inversely proportional to the measure of radius, and a spindle motor servo (25) responsive to the disc velocity signal, for controlling the angular velocity of the information disc (11) accordingly. The velocity signal circuitry includes a crystal oscillator (29) a counter (31) for counting the clock pulses produced by the oscillator, (29) and a digital word magnitude comparator (35) for generating a reset pulse to reset the counter (31) to an initial zero count every time it determines that the count is equal to the digital measure of radius. The disc velocity signal is then derived by frequency dividing the successive reset pulses.

Abstract: This invention relates to an improved method of preparing a zeolite composition in which some or all of the cations have been exchanged for gallium ions. The zeolite has a high silica to alumina ratio and is prepared by crystallisation from an aqueous solution containing a mixture of a source of silica, a source of alumina, and at least two other components selected from the group of alkali metal ions, ammonia and an organic nitrogen containing base. The improvement lies in washing the crystallized zeolite with acidified and / or deionised water, calcining the washed product at an elevated temperature, contacting the calcined product with an acid, refluxing the acid treated zeolite with a solution of a gallium compound to produce a gallium exchange zeolite and washing the gallium exchanged zeolite with waterto render it substantially free from any impregnated gallium or gallium compound. The zeolite composition is useful as a catalyst for hydrocarbon conversion reactions.

Abstract: Ein Supraleiter mit einer supraleitenden intermetallischen Verbindung aus wenigstens zwei Elementen lässt sich dadurch herstellen, dass ein Leitervorprodukt mit einer ersten, en Element der Verbindung enthaltenden Komponente und mit einer zweiten Komponente, die aus einer ein Trägermetall und das restliche Element bzw. die restlichen Elemente der Verbindung enthaltenden Legierung gebildet ist, erstellt wird und dass das Leitervorprodukt einer solchen Wärmebehandlung unterzogen wird, dass die Verbindung durch Reaktion des Elementes der ersten Komponente mit dem restlichen Element bzw. den restlichen Elementen der zweiten Komponente gebildet wird. Bei einem solchen Supraleiter ist man bestrebt, dessen effektive Stromdichte und kritischen Strom zu erhöhen. Die Erfindung sieht hierzu vor, dass die Wärmebehandlung in einer Wasserstoffatmosphäre vorgenommen wird. Ebensogut kann man aber auch nach der Wärmebehandlung zur Bildung der supraleitenden Verbindung eine thermische Nachbehandlung in einer Wasserstoffatmosphäre vornehmen. Nach diesen Verfahren hergestellte Supraleiter können insbesondere für supraleitende Einrichtungen vorgesehen werden, deren Magnetfelder Flussdichten oberhalb von 10 Tesla haben.
