Patent EP-0307983-A1 (EP)
Inventor: HIGMAN CHRISTOPHER
IPC: C01B3/50
Filed: 1988-08-18
Abstract: Ammonia synthesis gas comprising hydrogen and nitrogen is produced by starting from a gas mixture which is high in particular in hydrogen and carbon monoxide and contains methane as impurity. The gas mixture is converted catalytically (2) and the CO2 is removed (5) from the converted gas mixture which has a CO content of about 2 to 8 % by volume. The gas mixture is precooled to maximum temperatures of -50 DEG C (8) and cooled further in a heat-exchange zone to maximum temperatures of -160 DEG C. In the heat-exchange zone (11), the temperature of the high-hydrogen gas mixture drops below the dew point of methane, thus making it possible to separate off a condensate which is high in methane (13). In a washing stage (20) using liquid nitrogen, carbon monoxide is removed from the gas mixture as a condensate. In the heat-exchange zone (11), at least a portion of the condensate which is high in CO is evaporated and passed to the converting stage (30). A gas mixture containing H2 and N2 (24) is removed from the liquid nitrogen washing stage and also passed through the heat-exchange zone. <IMAGE>

Abstract: A fuel injection nozzle for supplying fuel to an internal combustion engine includes a valve member (17) which co-operates with a seating surface (14) in a nozzle body to prevent fuel flow through an outlet orifice (13) extending from a "sac" volume (16) downstream of the seating surface. The valve body and the valve member downstream of the seating surface define spaced parallel truncated conical surfaces which have a cone angle less than that of the seating surface. The surface defines a flow restriction gap the degree of restriction offered by the gap decreasing at a lower rate as the valve member is lifted from the seating surface, than the degree of restriction between the valve member (17) and the seating surface (14).

Melt-arresting means (135) are provided in the vicinity of the respective dis­charge ends of the pipe and passage to limit run back of molten metal in a space between the lance pipe (114) and the passage when the pipe has been advanced to its injection position, the arresting means (135) defining a clearance which affords ad­vancing movement of the pipe but is so small as to prevent significant flow of metal through the clearance. In case melt is not arrested by the arresting means (135), a compressible melt-impervious seal means (127) is provided adjacent an outer end of the pipe.

Abstract: An involute interpolation method for numerically controlled machining. The direction (G03.1) of rotation of an involute curve, coordinate (Xe, Ye) of a final point, center position (I, J) of a base circle as viewed from a start point, and radius (R) of the base circle are designated. Point sequences are found from two equations that represent an involute curve, and are interpolated, in orderto interpolate an involute curve over a range of an angle that corresponds to the range from the start point to the end point of the involute curve. In this case, the increment in θ is rendered to be K/(R.θ) which decreases with the increase in the angle, and the interpolation is so effected that the speed becomes constant in the tangential direction, such that the machining rate along the involute curve becomes constant.

Abstract: Die zu einem Ofen gehörigen Brenner werden zur Temperaturregelung mit Hilfe eines geschlossenen Regelkreises geregelt. Der Regelkreis enthält eine Temperaturmeßeinrichtung, einen Regler zur Temperaturregelung, eine die Reglerausgangsgröße in eine geeignete Stelleistung der Brenner umsetzenden Stelleinrichtung, ein digitales Zentralsteuergerät, welches die Zykluszeit (tZ), die Impulsbreite (tE) der Einschaltimpulse des Brenners und deren Impulsabstand (tA) bestimmt. Eine minimale Zykluszeit (tZmin) aus der Summe aus minimaler Impulsbreite (tEmin) und minimalem Impulsabstand (tAmin) wird voreingestellt und als Stelleistungs-Bezugsgröße verwendet. Ausgehend von dieser Stelleistungs-Bezugsgröße bei minimaler Zykluszeit wird die Stelleistung der Brenner bedarfsgerecht unter Änderung der Zykluszeit (tZ) entweder durch Impulsabstands- oder durch Impulsbreitenvariation geregelt. Bei geringeren Stelleistungen wird der Impulsabstand vergrößert, und bei gegenüber der Bezugsgröße vergrößerten Stelleistungen wird die Impulsbreite bei konstantem minimalem Impulsabstand vergrößert. Dadurch kann der Stellbereich pulssteuerbarer Brenner bei jeweils minimaler Zykluszeit und entsprechend raschen Regelantworten wesentlich vergrößert werden.

Abstract: Der Transformator (9) eines Sperrwandlers wird in der Flußphase, in der ein primärseitiger Schalter (7) eingeschaltet ist, durch Energieaufnahme aufmagnetisiert und in der Sperrphase, in der der Schalter (7) ausgeschaltet ist, durch Energieabgabe an die sekundärseitige Last abmagnetisiert. Der Schalter (7) sollte erst nach völliger Entmagnetisierung des Transformators (9) wieder eingeschaltet werden. Um dies zu gewährleisten, wird vorgeschlagen, eine Transformatorspannung (Rückkopplungsspannung) zu bilden und das Einschalten des Schalters (7) erst dann freizugeben, wenn die Rückkopplungsspannung von Werten mit einem ersten Vorzeichen zu endlichen Werten mit dem entgegengesetzten Vorzeichen übergegangen ist. Um dabei ein Anschwingen zu ermöglichen, muß der Schwellwert (23) bei Inbetriebnahme des Schaltnetzteiles zunächst vom Wert Null ausgehen und solange bei diesem Wert bleiben, bis die Spannung über der Last anzusteigen beginnt. Diese Schwellwertverschiebung läßt sich durch eine einfache Anderung in der Außenbeschaltung von bereits existierenden Ansteuerbausteinen realisieren.
