Title: Gegentakt-B-Verstärker mit Eintaktausgang
IPC: H03F3/30
Filed: 1983-02-17
Granted: 1985-04-18
Abstract: Es wird eine Verstärkerausgangsschaltung offenbart, bei der eine Überschneidungsverzerrung in hohem Maß ausgeschaltet, eine Temperaturkompensation des Blindstroms vermieden und der Blindstrom unabhängig von der Größe des Eingangssignals stabil gehalten wird. Im einen Fall, wobei zwei den Ausgang verstärkende Elemente in einer SEPP-Schaltungsanordnung der Klasse B geschaltet sind, sind ein erster und zweiter Fehlersignalverstärker vorgesehen. Während der erste Fehlerverstärker als ein solcher für einen zwischen der Spannung an der Ausgangselektrode seines stromverstärkenden Elements und der Spannung am Schaltungseingangsanschluß verschobenen Fehlerspannungspegel arbeitet, arbeitet der zweite als ein Fehlerverstärker für einen zwischen der Spannung am Ausgangsanschluß seines verstärkenden Elements und der Spannung am Schaltungsausgangsanschluß verschobenen Fehlerspannungspegel. Während andererseits der zweite Fehlerverstärker als ein solcher für den zwischen der Spannung an der Ausgangselektrode des zweiten verstärkenden Elements und der Spannung am Schaltungseingangsanschluß verschobenen Fehlerspannungspegel wirkt, wirkt der erste als ein Fehlerverstärker für einen Fehlersignalpegel, der zwischen der Ausgangsspannung des ersten verstärkenden Elements und der Spannung am Schaltungsausgangsanschluß verschoben ist. Bei einer anderen Ausbildung ist eine Brückenschaltung zwischen den Schaltungsausgangsanschluß und die Ausgangselektrode des den Ausgang verstärkenden Elements .......

Title: Gleichlaufeinrichtung für mindestens zwei Hubtische mit hydraulischen Arbeitszylindern
IPC: B66F3/46
Filed: 1983-10-21
Granted: 1986-05-28
Abstract: Die Erfindung betrifft eine Gleichlaufeinrichtung für mehrere hydraulische Antriebszylinder, insbesondere für Hubtische. Eine Relativbewegung jeweils zweier Zylinder wird von einem schwenkbaren Stellglied erfaßt, welches ein Gleichgangventil betätigt, welches den Druckraum des zugehörigen Antriebszylinders mit einer Druckmittelquelle bzw. mit dem Tank verbindet. Beim Heben wird der voreilende Antriebszylinder verlangsamt, indem aus dem Druckraum Druckmittel entnommen wird. Läuft der Zylinder dagegen nach, so wird dem Druckraum über das Gleichgangventil zusätzlich Druckmittel zugeführt, bis der Synchronlauf hergestellt ist, indem das Gleichgangventil den Druckraum absperrt.

Title: Two=stroke IC engine
Inventor: KAGEYAMA MINORU
IPC: F02B33/30
Filed: 1984-08-31
Granted: 1996-03-21
Abstract: The two-stroke engine comprises a chamber (20) connectable to the exhaust duct (18) via a rotary valve (28) and an inlet duct (12) contg. a reed valve (16) which oscillates between a closed and a partly open position. The two valves are intercoupled (32) such that closure of the valve (28) lifts the inlet reed valve into its permanently open position and vice versa, a servo-motor being provided to operate one of the valves, i.e. to close the valve (28) above a given engine speed. Optimum engine operation at low speed is obtained when the rotary valve is open (as shown) to optimise exhaust ducting volume whilst the reed valve (16) oscillates to optimise charging. At high speed, closure of the valve provides optimum exhaust ducting volume and lifting the reed valve prevents undesirable resonance flutter.

Patent DE-3624806-C2 (DE)
IPC: B23C3/30
Filed: 1986-07-23
Granted: 1990-11-08
Abstract: A method of machining an axially parallel groove in the periphery of a shaft includes fixedly mounting the shaft in the main spindle of a CNC turning machine, moving a rotating milling tool (whose diameter decreases in a direction from its free end and whose maximum diameter is less than the desired width of the groove) radially and axially of the shaft so as to form a first portion of the groove and to finish one of the lateral surfaces which bound the groove, extracting the tool and changing the angular position of the shaft through an angle which equals or approximates the taper of the tool), and again moving the tool axially of the shaft to complete the machining of the groove and to simulaneously form the other lateral surface. The tool can be reground a substantial number of times so that its useful life is a multiple of that of cylindrical milling tools having a diameter which matches the desired width of the groove.

IPC: A61F2/48
Filed: 1990-12-07
Granted: 1992-10-15
Abstract: This device consists of an adaptor 1 which is to be arranged between two endoprosthesis parts, and of a pump 9 which can be actuated manually and is provided with or connected to a liquid reservoir 8. The adaptor 1 consists of two interlocking, displaceably mounted sleeves 3, 4, which are closed at the head end and one of which has in its interior a piston 11 which can be moved longitudinally in the interior of the other sleeve 4, and enclose together with the inner head end of the other sleeve 4 a liquid-tight and liquid-filled pressure chamber 7. The pressure chamber 7 is connected via a pressure line 10 to the pump 9. Pump, pressure line and pressure chamber form a self-contained hydraulic system. Liquid is pumped into the pressure chamber 7 by actuating the pump, after which the outer sleeve executes a movement in the expansion direction X. It is possible to provide as securing system toothed strips 12 and 13 on the inner sleeve 4, which cooperate with toothed strips of locking jaws 18 and 17, respectively, in such a way that the toothed strips are locked when there is no pressure in the pressure chamber 7. The locking can be abolished when pressure is applied to the pressure chamber 7 so that the movement in the expansion direction X of the sleeve 3 is possible. The device can be implanted as a unit. Expansion of the adaptor to be performed postoperatively is possible without invasive intervention. <IMAGE>
