Abstract: Hydrogenatable compounds, particularly olefins and aromatic compounds, in a hydrocarbon feedstock boiling above 200°F (93.3°C) are hydrogenated at a temperature in the range of from 400°F-720°F (202.1 to 382°C) using a zeolite-containing catalyst that has been treated with a hydrocarbon stream relatively high (more than 100 ppm N) in organic nitrogen compounds to suppress the cracking activity of the catalyst. The catalyst comprises (1) an amorphous base component, (2) a crystalline aluminosilicate component preferably comprising from 5-30 wt. % of the total catalyst and having a silica/alumina mole ratio of at least 2.5 and an alkali metal content of less than about 2.0 wt.% and (3) a transition metal hydrogenation component. The process is particularly useful in the manufacture of jet fuels and technical white oils and white oil bases with a minimum conversion of feed (less than 20%) to substantially lower boiling products.

Abstract: A hydraulic system includes a selective control valve and a cam member movable to selected positions for controlling a hydraulic cylinder powered by a pump. A follower is urged to a locking relationship with the cam by a hydromechanical mechanism to releasably hold the control valve in the selected positions. The hydromechanical mechanism includes a bore exposed to sump pressure and to pressure upstream and downstream from a metering valve in a passage interconnecting the pump and the control valve. A hollow apertured sleeve is movably mounted in the bore. An apertured piston is slidably received by the sleeve. A rod, engageable with the follower, extends through the piston and sleeve apertures. A first spring interconnects the rod and the piston and a second spring interconnects the piston and the sleeve. The sleeve moves to a preload position in response to a no-flow differential pressure between the sump and the passage to urge the follower via the rod towards its locking position. The piston moves in response to fluid flow through the passage to bias the follower toward its locking position. The piston and the rod move to automatically allow the follower to release from the cam when the function of the hydraulic cylinder is completed. Also, the sleeve and rod move to automatically allow the follower to release from the cam when system pressure in the passage is lost.

Abstract: Die Erfindung befaßt sich mit einem Verfahren und einer Vorrichtung zur Durchführung des Verfahrens zum einseitigen Beschichten von durchlaufendem Band, insbesondere zum Verzinken von Stahlband (B). Dabei wird das um eine horizontal umlaufende Umlenkrolle (2) geführte Band mit Hilfe einer unterhalb der Umlenkrolle (2) achsparallel dazu angeordneten, in das Beschichtungsmedium mit mindestens der Hälfte ihres Umfanges eintauchenden Schöpfrolle (3) mit flüssigem Beschichtungsmedium (4) benetzt. Die gesamte Anlage arbeitet unter Schutzgas. Es hat sich gezeigt, daß, wenn das beschichtete Band die Schutzgasatmosphäre mit einer zu hohen Temperatur verläßt, die nicht beschichtete rückwärtige Oberfläche des Bandes oxidiert bzw. anläuft, was für die Weiterverarbeitung des Bandes nachteilig ist. Davon wird die Aufgabe der Erfindung abgeleitet, ein Verfahren und eine Vorrichtung zu schaffen, mit dem bzw. mit der es möglich ist, ein einseitiges Band mit reiner, nicht oxidierter unbeschichteter Rückseite herzustellen. Zu diesem Zweck wird vorgeschlagen, die Oxidschicht auf der Oberfläche der nicht beschichteten Seite mechanisch abtragend zu bearbeiten. Vorrichtung zur Durchführung dieses Schrittes können rotierende Werkzeuge, sie Metall- oder Kunststoffbürsten sein oder aus Werkzeugen bestehen, die ein mit Schleifpartikeln durchsetztes Fließ aus synthetischen Phasern aufweisen.

Abstract: An electric cooker or cooking hob has a ceramic plate (2) on which there are a number of hot plate areas each heated by a respective annular heating element (4) disposed within an insulating housing (7). Atemperature dependent resistor (9) is disposed below the hot plate area at the centre of focus of a reflector (8) which is arranged to focus radiant energy from the hot plate area onto the resistor (9) while at the same time shielding the resistor (9) from direct radiation from the electric heating element (4). The signal derived from the resistor (9) is a measure of the temperature of the hot plate and can be used to provide a thermal tripping function to prevent over-heating of the hot plate area and/or to carry out closed loop control of the temperature of the hot plate area. The reflector (8) may be replaced by a shield which shields the resistor (9) from direct heating by the heater. 
     A further annular heating element surrounding the element (4) may be provided, with the control circuitry enabling either the element (4) alone or element (4) plus the outer element to be energised.
