Patent DE-4407569-A1 (DE)
Title: Approximate detection of alternating parameters
Inventor: WOLF JOHANN DR
IPC: G01R19/12
Filed: 1994-03-07
Abstract: The time is measured between at least two points (T1,T2) in each half wave of the alternating current between its null crossing and peak value. The detection of the time points is performed using current sensors of different sensitivity. These are current converters with a Z characteristic, whose pulse determining products of coercivity field strength and iron path length are different. A threshold stage with two different threshold values which acquires the measurement parameter is connected in series with a flip stage, AND gate and counter. The AND gate also has an oscillator connected to its input side and the counter is synchronized by the threshold stage, which operates with at last two current converters with Z characteristic iron cores and different products of coercivity field strength and iron path length.

IPC: F02M25/08
Filed: 1994-11-24
Abstract: The present invention relates to a valve arrangement, especially for a line from a fuel vaporisation restraint system to an intake manifold of an internal combustion engine, with a housing having a first housing section (10) with an inlet aperture (11), a second housing section (15) sealed to the first (10) with an outlet aperture (19), a flow path from the inlet to the outlet aperture (11, 19) blockable by a closer (33) and an acceptance chamber in which there is an actuating device (23) for the closer (33).

Patent DE-4447286-A1 (DE)
Inventor: LANGEN HERBERT DIPL ING
IPC: F01N3/025
Filed: 1994-12-30
Abstract: The invention concerns a vehicle heater in which an exactly metered amount of fuel per unit time is fed to a burner by a pump. A fan (12) supplies, in dependence on the amount of fuel, the appropriate amount of air for optimum combustion. Since conventional fans have wide tolerance ranges, i.e. since the air-flow rate stated for a given fan speed is in fact subject to considerable fluctuations, an air-flow sensor (8) is fitted in the combustion-air inlet duct to ensure combustion is always optimum, the heater control unit (4) controlling, in dependence on the measured air flow, the rpm (n) of the electric motor (10) which drives the fan.

Title: Installation for the manufacturing of components having an internal and/or external polygonal shape
Inventor: RAMBOW PETER
IPC: B23Q27/00
Filed: 1985-05-23
Abstract: A conventional lathe-type machine. A spindle (18) with a chuck (20) for the workpiece is secured in a conventional manner on a machine bed (10). Also fixed to the machine bed (10) are two other shafts (52, 56). The drive motor (22) which causes the spindle (18) to rotate, also drives, via a gear change box (36) the two shafts (52, 56). Fixed to one shaft (52), via a radial movement component, is a bearing (60) for a tool-carrier (62). In accordance with the drive system, the latter is connected by means of a radial movement component (78) with the other shaft (56). When the spindle (18) and the two shafts (52, 56) rotate, the tool held on the tool-carrier (62) moves along a closed trajectory, which is the result of the superimposition of the trajectories of the tool carrier (62) and the bearing (60). At the same time, the tool also performs a movement of its own. As a result, the tool is thus obliged to follow a trajectory which, when applied to the also rotating workpiece, causes the part to be cut so that it has not a circular shape, as in the case of a conventional lathe, but a shape which is polygonal. It is possible to produce, for example, rectangular parts. The special feature of this system is that the masses which are moved eccentrically are small. Only the tool-carrier (62) and the tool are moved eccentrically.

Title: Process for treatment of aluminium melts
Inventor: GLOZ MICHAEL
IPC: C22B21/06
Filed: 1985-12-17
Abstract: The process for the treatment of aluminium melts consists in the introduction of a treatment means and serves to reduce in a reliable manner the alcaline metal impurities which interfere with the subsequent processing of the aluminium. For this, porous particles are introduced into the melt, the said particles being of an inert material in respect to molten aluminium, and having a particle size of < 10 mm, preferably from 5 mm to the fineness of a dust. The porous particles are charged with air oxygen which is desorbed inside the melt in an extremely finely distributed manner and thus result in the oxidation of the troublesome alkaline metals. The porous particles can consist of a carbon material which acts as an adsorption means, for example calcined coal (e.g. oil coke, byproduct coke and anthracite), graphite, soot or activated carbon. However, other materials also can be considered, for example active aluminium oxide and/or magnesium oxide, oxide or silicate ceramics as well as adsorption means based on silicic acid, such as silica gel, aerosil and/or active earth. All of these materials can be used alone or mixed with any of them. The particles can be mixed into the melt mechanically, but preferably they are blown into it by means of air or inert gases or by mixtures of air and inert gases. In addition, still other treatment means can be added to the particles and/or to the gases used for blowing them in.

Abstract: Der in einer Strang- oder Rohrpresse erzeugte Strang wird mit einer geregelten, den auslaufenden Strang gestreckt haltenden Zugkraft abgezogen, durch die die Strangbildung nicht beeinflußt werden soll. Um die im Matrizenbereich auf den Strang wirkende Zugkraft konstant zu halten, wird erfindungsgemaß so verfahren, daß dieser dem Querschnitt und dem Fließverhalten in der Matrize angepaßten Zugkraft (Abziehkraft) eine proportional zur ausgepreßten Stranglänge zunehmende, das Längeneinheitsgewicht und den Reibungswert zwischen Strang und Auslauftisch berücksichtigende Zugkraft (Abschleppkraft) überlagert wird. Insbesondere wird hierzu nach dem Abtrennen eines Stranges und dessen Ausziehen aus der Matrize die Abschleppkraft und die Länge des ablaufenden Stranges gemessen und die Abschleppkraft dividiert durch die Stranglänge beim Auspressen eines folgenden Stranges gleichen Sollquerschnitts als Vorgabe für die mit der durch Wegmessung ermittelten Stranglänge zu multiplizierende spezifische Profilreibkraft eingegeben. Die Steuerung erfolgt derart, daß als Sollwert der auf die Strangspitze ausgeübten Zugkraft zusätzlich zu einem den Fahrwiderstand des Wagens der Abziehvorrichtung berücksichtigenden Wert als erstem Summanden und einem vom Strangquerschnitt abhängigen Grundwert der Abziehkraft als zweitem Summanden beginnend mit dem Erfassen der Strangspitze durch die Greifer der Abziehvorrichtung ein zunehmender, als jeweiliges Produkt des Ergebnisses fortlaufender Austrittswegmessung und vorgegebener spezifischer Profilreibungskraft zwischen auslaufendem Strang und Auslauftisch sich ergebender Wert als drittem Summanden ermittelt und eingegeben wird.
