Patent number: 4618747Abstract: To be able to disengage the contacts of a switch in the event of a breakage of the snap spring or if the contacts become melted together, a pivotable resetting member in the form of a two-armed lever is provided. One arm of the lever is associated with the inside end of an operating plunger, while its other arm is associated with the end of a slide of the switch. While being displaced from its initial position into the switched position, the slide pushes the resetting member and the end of the operating plunger moved thereby away from the respective arm of the resetting member. By pushing the operating plunger against the actuator, the end of the plunger acts against the arm of the resetting member whose pivotal motion then causes the slide to be pushed into its initial position.Type: GrantFiled: October 3, 1984Date of Patent: October 21, 1986Assignee: Marquardt GmbHInventor: Alois Schaffeler

Patent number: 4618781Abstract: A gate turn-off thyristor comprising, a first emitter layer of one conductivity type, a main base layer of another conductivity type connected to said first emitter layer and a control base layer of the first conductivity type connected to the main base layer. A second emitter of the other conductivity type is connected to the control base layer at a junction which surrounds a portion of the second emitter layer. An emitter contact is connected to the second emitter layer and a control base contact is connected to the control base layer. The gate turn-off thyristor is turned off by a short circuiting of the control base contact with the emitter contact. The surface resistance of the control base layer between the second emitter layer and the control base contact is selected so that, with a control base turn-off current applied which is sufficient for turning off the thyristor, a potential appears on a lateral resistance in the control base layer which is less than a potential appearing at the junction.Type: GrantFiled: March 20, 1981Date of Patent: October 21, 1986Assignee: Licentia Patent-Verwaltungs-G.m.b.H.Inventors: Dieter Silber, Friedhelm Sawitzki, Kurt Roy

Patent number: 4616447Abstract: In uninterrupted and neat machining of a workpiece or material, particularly extremely hard material, with an ultrosonic tool is obtained by keeping constant or substantially constant the contact pressure between the tool and the worked surface. This is done, for example, by feeding the tool by means of a spindle sleeve which is mounted for displacement in a feed head. The other end of the spindle sleeve, remote from the tool, is designed as the piston of a feed mechanism. By keeping the pressure P1 in the cylinder space above piston, or the volume of this cylinder space, constant, the contact pressure of the tool remains constant as desired. Since the piston displaced during the matching operation, this displacement must be determined, by means of a displacement pickup, for example. Through a very sensitive contact pressure control on a feed head of the working machine, to which the cylinder of the feed mechanism is secured, can be moved to keep the volume of or pressure in the cylinder space constant.Type: GrantFiled: February 27, 1984Date of Patent: October 14, 1986Assignee: Mafell-Saschinenfabrik Rudolf Mey GmbH & Co. KGInventors: Rudiger Haas, Ernst Krauss, Herbert Walter

Patent number: 4616582Abstract: At a work clamp for buttonhole sewing machines, comprising a support plate and a clamping frame arranged at a pivotable carrying lever, spaced from the clamping frame, a hold-down device with a clamping plate resiliently pressed against the work is fastened at the carrying lever. The clamping frame, when raised is pressed into a slanting position by a spring. During the descending movement of the clamping frame and hold-down device, the hold-down device precedes the clamping frame and clamps the work to the support plate. As a next step, the edge of the clamping plate of the clamping frame which is spaced from the hold-down device impinges on the work. A clamping surface of the clamping plate forms an acute angle with the support plate. As the descending movement of the clamping plate continues, the clamping frame swings out about its bearing pin on the carrying lever. At this time the edge engaging the work moves away from the hold-down device.Type: GrantFiled: March 13, 1985Date of Patent: October 14, 1986Assignee: Pfaff Industriemaschinen GmbHInventor: Walter Hager

Patent number: 4616384Abstract: A clamp which can be used separately to connect two rod-like members together at any angular relationship, can be used in conjunction with a frame for connecting a frame supporting rod thereof to the rod of a tripod or other rod or post-like member. The clamp comprises two clamp plates pivotally connected to each other with opposite rod engaging ends, and a third plate rotatably mounted to one of the pivotally connected plates. A threaded rod extends through substantially aligned openings in the three plates and can be tightened to squeeze the three plates together. While a first rod-like member can be held between the pivotally connected plates, a second rod-like member can be held between the rotatable plate and the associated one of the pivotally mounted plates.Type: GrantFiled: April 30, 1985Date of Patent: October 14, 1986Assignee: Lowel-Light Manufacturing, Inc.Inventors: Ross Lowell, Marvin Seligman, Edward Calamai

Patent number: 4617675Abstract: Plural series of digital pattern data are determined by PWMing a sine wave by a triangular wave and further classified into each series by the number of triangles included within a half cycle of the sine wave. An appropriate series of data are selected according to a frequency command. The selected data are further adjusted in response to a voltage control command. On the basis of the selected and adjusted pattern data and in response to a half period signal of triangular wave and triangle slope signals, a PWMed pulse is generated through a logical circuit. In the case where the generator is incorporated with an induction motor driving system, it is possible to control speed (frequency), torque (voltage), rotational directions, and torque fluctuations (phase difference) of an induction motor accurately at high response speed.Type: GrantFiled: March 8, 1985Date of Patent: October 14, 1986Assignee: Kabushiki Kaisha MeidenshaInventors: Tadashi Ashikaga, Yoshihide Kamanaka, Keiko Fushimi
