Patent EP-0017918-A1 (EP)
Inventor: PAPPAS NICHOLAS L
IPC: B41J9/44
Filed: 1980-04-10
Abstract: The technical field of this invention is impact printers, particularly impact printers of the "daisywheet" type. 
     In a 'daisywheel' printer, a print hammer (13) is actuated by a pivoted print arm (21). The arm carries a magnetic armature (24) which is attracted by a magnetic core (26) having two pole pieces. A pair of coils (27, 28) are wound about respective pole pieces and, when selectively energized, cause the print arm to depress the print hammer with any one of three impact forces (F 1 , F 2 , F 1  + F 2 ). The decision as to which force is used is a function of the area of the particular alphanumeric character to be printed and/or the number of copies to be printed.

Abstract: A freewheel device for connecting a power input (16) to a selected one of a plurality of outputs (19, 25) so as to transmit rotary motion in one direction of rotation and to over-run when the speed of the selected one of the outputs exceeds that of the input, includes a neutral condition in which the input is rotationally disengaged from any of the outputs. In a described embodiment, the freewheel device comprises a plurality of rollers (50) retained circumferentially adjacent one end of an axially movable shaft (17) in operative association with a plurality of wedge-shaped portions formed on the shaft, axial movement of the shaft serving to engage the rollers between the wedge-shaped portions and, selectively, axially spaced-apart internal cylindrical surfaces formed on each of the outputs and on a rotatable support (41) 
     The freewheel device finds particular application in the transmission system of multi-engined helicopters.

Abstract: New phospholipids containing a conjugated di-yne system have the formula:
     wherein at least one of 8, and B 2  is a group of the formula
     wherein p is 0 or 1, X, is a direct bond or a divalent aliphatic or cycloaliphatic group, Y, is H or a monovalent aliphatic or cycloaliphatic group, the total number of carbon atoms in X, and Y, in each of B, and/or B 2  being 8 to 26; and the other of B, and B 2  is either (a) the same or a different group of the formula
     where X,, Y, or p are as defined above; or (b) is an aliphatic or cycloaliphatic group containing at least 8 carbon atoms; n is 0 or 1, m is 2, 3 or 4 and each R independently represents an alkyl group containing 1 to 4 carbon atoms, and are prepared by esterification and/or etherification of glycerol by conventional techniques. The conjugated di-yne systems can be cross-linked by actinic radiation to give intermolecular and, in certain cases, also intramolecular cross-linking. Thin layers of the phospholipids can be coated onto substrates subsequently to be brought into contact with blood or other body fluids and then cross-linked to give polymer coated surfaces which have a reduced tendency to initiate blood coagulation, for example, compared to untreated surfaces. Artificial lenses for the human eye treated in this way have a reduced tendency to cause endothelial damage. The phospholipids of the invention can also be formed into liposomes and the conjugated di-yne system then cross-linked. Physiologically active materials such as drugs, enzymes or antigens can be incorporated into the liposomes which can then be used as prolonged release formulations.

Abstract: An internal combustion engine having at least one cylinder with inlet and exhaust valves operated via rocker arms by respective cams carried by a single camshaft. The camshaft is connected to its drive by an eccentric linkage, the eccentricity of which is varied by a device responsive to engine speed, and is least at high speed. As engine speed falls, increasing eccentricity results in a relative advance of inlet valve closing time and relative retardation of exhaust and inlet valve opening times but little change in the timing of exhaust valve closure. The lift of the valves may be varied also if the rocker arm axes are movably mounted.

Abstract: Die Erfindung betrifft ein Verfahren zur Hydrierung von Kohle. Der Erfindung lag die Aufgabe zugrunde, ein alternatives Kohlehydrierungs-Verfahren bereitzustellen, das nicht nur kostengünstig, sondern auch einfach durchgeführt werden kann und nur einen verhältnismäßig geringen Aufwand an Vorrichtungen, Überwachungseinrichtungen und Personal benötigt. Das Verfahren soll auch ohne Störungen in Anwesenheit von bestimmten Verunreinigungen ablaufen, die bei bekannten Kohlehydrierungs-Verfahren Vergiftungserscheinungen hervorrufen und somit das betreffende Verfahren im Hinblick auf Ausbeute oder auf Durchführbarkeit in Frage stellen. Diese Aufgabe wurde nach der Erfindung dadurch gelöst, daß einer gesättigten Lösung von Kohlenstoff in einem metallischen Medium bei einer Temperatur unterhalb 900 K ein wasserstoffhaltiges Gas zugeführt wird und daß die Umsetzung von C und H zu Kohlenwasserstoff-Verbindungen innerhalb des Mediums erfolgt. Die Umsetzungsreaktion zwischen C und H kann in einer Metall-Schmelze durchgeführt werden, beispielsweise in einer Alkali-Metall-Schmelze bei einer Temperatur im Bereich von 673 K und 873 K, in die das wasserstoffhaltige Gas mit einem Druck im Bereich von 1,5 bar bis 15 bar eingepreßt wird. Die Kohlenwasserstoff-Verbindungen werden mit Hilfe von Kondensation und/oder Absorption aus dem aus der Metall-Schmelze abgezogenen Gas abgeschieden.

Abstract: The plant consists of large water towers (2, 7) set up in a circle, between which wind turbines (16) are arranged and on whose walls parabolic reflectors (22) and solar collectors (24) are mounted. Pumps driven by the wind turbines via generators convey water to raised containers (6) in order to feed the water turbines in this way. The steam generated in the solar collectors drives steam turbines coupled to generators. In order to store the wind and solar energy for periods with little wind and sun, the heated water presses, in common with hydrogen produced in some towers, against the water level of a water pump (26). A central tower (9) contains the generators, the pumps and the turbines. <IMAGE>

Abstract: Durch α und β-Teilchen enthaltende Proben werden mit einem Detektor nach Patentanmeldung P 3 003 909.9-33 Detektorimpulse erzeugt, deren Vorderflanken während einer vorbestimmten Zeit teilchenspezifisch annähernd konstant ansteigen und die von α-Teilchen erzeugten Impulse eine erste Steigung α aufweisen, die wesentlich größer ist als eine zweite Steigung β der von β-Teilchen erzeugten Impulse. Dieses von der Energie der Teilchen weitgehend unabhängige physikalische Phänomen wird zur Diskriminierung verwendet. Dabei wird der lineare Anfangsbereich der Vorderflanke des Detektorimpulses im Nanosekundenbereich zeitdiskriminiert. Während der durch die Zeitdiskriminierung vorbestimmten Zeit erreichen die Detektorimpulse von α-Teilchen wesentlich höhere Amplitudenwerte als die von β-Teilchen verursachten Detektorimpulse. Die Amplitude des zeitdiskriminierten Detektorimpulses wird durch Amplitudendiskrimination bestimmt und in Triggerimpulse umgesetzt, die einen ersten Zähler für eindeutige α-Ereignisse oder einen zweiten Zähler für eindeutige β-Ereignisse triggern. Bei einem sehr kleinen Teil der Detektorimpulse, dessen durch Zeitdiskriminierung gewonnene Amplituden nicht eindeutig α- oder β-Ereignissen zuzuordnen sind, wird ein dritter Zähler getriggert, der die Güte der Messung anzeigt.
