Abstract: Bei einem elektrisch betriebenen Handarbeitsgerät (1) ist der einen axial verschiebbaren Schlagkörper (32) betätigende Elektromotor als Wechselstrom-Schwinganker-Motor (12) mit einseitig schwenkbar gelagertem Schwinganker (15) ausgebildet, der in Abhängigkeit von der Netzfrequenz mit hoher Schlagfolge auf den mit geringer Masse ausgestatteten Schlagkörper (32) einwirkt. Und dieser ist der Frequenz des Ankers (15) folgend in einem ortsfest in einem Gehäuse (11) des Gerätes (1) gehaltenen Zylinder (31) eingesetzt, mit dem eine Vorsatzhülse (41) lösbar kuppelbar ist, die einen durch den Schlagkörper (32) gegenüber dieser verschiebbaren, auf ein einzutreibendes Teil (2) oder ein Werkzeug einwirkenden Stößel (43) aufnimmt. Durch diese Ausgestaltung wird es ermöglicht, einen Nagler od. dgl. äußerst kompakt zu bauen, da der mit dem Schlagkörper (32) versehene Zylinder (31) unmittelbar neben dem Wechselstrom-Schwinganker-Motor (12) angeordnet werden kann. Außerdem sind die Leistungsverluste gering, da der um eine Achse verschwenkbare Schwinganker (15) direkt auf den massearmen Schlagkörper (32) einwirkt. Des weiteren können für unterschiedliche Verwendungszwecke ausgelegte Vorsatzhülsen mit dem Zylinder (31) gekoppelt werden.

Abstract: In color TV receiver for SECAM-encoded signals, a single FM detector (15), subject to line-by-line switching of its center frequency tuning, achieves sequential demodulation of respective SECAM subcarriers. For the purpose of using an identification system of the type shown in U.S. Patent No. 4,240,102, center frequency tuning at the R-Y subcarrier resting frequency is held throughout R-Y line interval and during lead-in burst of B-Y line interval, terminating at beginning of image portion of B-Y line interval. Transient signal component, associated with switching to B-Y subcarrier resting frequency at beginning of that image portion, tends to be stretched into early segment of image portion by de-emphasis circuit (19) following FM detector. To reduce adverse effects of this on colouring of image at left edge, a differentiated version of a pulse (at terminal D) having an appropriately directed trailing edge coinciding with transient is delivered to de-emphasis circuit output terminal (0). Elements (61, 63) of the de-emphasis circuit preferably serve as differentiator.

Title: Servo-controlled spindle drive system
Inventor: LOHNEIS EARL R
IPC: G05D3/00
Filed: 1982-07-21
Abstract: An Improved spindle drive train for rotatably driving the spindle of a machine tool comprises a frame fastened to which is a motor whose shaft extends into the frame. Keyed on that portion of the motor shaft extending into the frame is a pinion gear which is in meshing engagement with one of the gear members of a cluster gear joumaled in the frame for rotation about and transverse movement along an axis parallel to the motor shaft. Journaied into the frame parallel to the cluster gear is the tool-carrying spindle which has a shaft extending coaxially therefrom within the frame. The spindle shaft carries a plurality of gear thereon, each dimensioned to meshingly engage a corresponding cluster gear member, and each is aFigned with one another so that when the spindle is at a predetermined angular orientation, the teeth on each of the gears line up permitting axial shifting of the cluster gear. The gears on the spindle shaft are spaced apart such that as the cluster gear is biased along its axis, one of the gears on the spindle shaft and its complementary cluster gear member engage just as another gear and its complementary cluster gear member disengage, assuring constant synchronism between the spindle and the motor. Motor shaft position is obtained by a resolver fastened directly to the motor shaft, thereby preventing excessive resolver back lash.

Abstract: In order to provide improved flexibility of operation consistent with small size. low mass and low inertia, a self-propelled drawing device 2 or 3 is driven by two independent wheels 12 whose axes are fixed, and has a writing tip 17 which marks the drawing medium 1 at a point which is not on the imaginary line joining the points of contact of the wheels with the drawing medium. In order to provide a simple umbilical cord which is less likely to impede the movement of the drawing device, the drawing device is connected to a stationary control device 5 by flexible conductors in the form of a ribbon 4 whose width lies in a vertical plane. Instead of a drawing device, the device can be arranged as a tracing device with counters on the wheels and a tracing tip instead of the writing tip.

Abstract: Apparatus (37) for introducing sweep gas through a baffle system (52) adapted for use with glow discharge deposition apparatus in which successive amorphous semiconductor layers are deposited on a substrate (11). The deposition apparatus includes at least a pair of adjacent dedicated deposition chambers into each of which different process gases are introduced, the chambers being operatively connected by a gas gate. Inert gases introduced into a first one of the adjacent chambers are unidirectionally swept through the gas gate to minimize back diffusion of process gases from the other of the chambers. The baffle system (52) is adapted to prevent said sweep gases from entering into turbulent flow when traveling through the gas gate passageway. Further, a sufficient volume per unit time of sweep gas is introduced to insure that some sweep gas flows into the cathode region of the first chamber, thereby substantially preventing process pases and plasma from escaping from the cathode region and forming silane powder.

Abstract: Eine elektrolytische Metallrückgewinnungszelle besitzt ein Gehäuse (1,2) mit Einlaß (4) und Auslaß für eine Lösung, aus der Metall rückgewonnen werden soll, sowie eine im Gehäuse drehbar gelagerte zylindrische Kathode (9). Das Gehäuse enthält eine Anode (7) und ein Schneidmesser (22), welches so befestigt ist, daß es in der Lage ist, beim Betrieb der Zelle auf der gesamten Seitenfläche der Kathode abgeschiedenes Metall zu entfernen. Um den Betrieb der Zelle zu steuern sind elektrische Mittel zum Antrieb des Schneidmessers in vorbestimmten Zeitabschnitten ohne Berücksichtigung der Elektrolysebedingungen und zum Betätigen des Schneidmessers (22), wenn das überwachte Kathodenpotential um einen vorbestimmten Betrag von einem Sollwert abweicht, vorgesehen. Hierdurch wird die Verwendung von früher vorgeschlagegen Abkratzern vermieden, und die Zelle läßt sich leicht sowohl unter stationären Elektrolysebedingungen als auch bei starken Schwankungen in der Metallionenkonzentration der Lösung betreiben. Die Zelle und deren Betrieb sind bei Verwendung zur Rückgewinnung von Silber aus verbrauchten photographischen Fixierlösungen beschrieben, doch können sie auch zur Wiedergewinnung anderer Metalle angewendet werden.

Abstract: A method and a device for exhaust emission control for diesel engines including a trap (12) in the form of a filter formed of heat-resting material for catching carbon particulates. The trap has no directional effect with respect to air permeability, and combustion gas for heating the trap or a fuel for activating a catalyst provided to the trap is supplied to the trap from a direction which is substantially perpendicular to a direction in which an exhaust gas flows from the engine to the trap. Thus, then obturation of the trap occurs as a result of accumulation of the trapped carbon particles, such particulate material can be readily removed by oxidation treatment, to thereby enable regeneration of the trap to be effected with a high degree of efficiency-
