Patent number: 4951023Abstract: An electromagnetic drive apparatus for undertaking linear or circular movements as a flat coil disposed within a magnetic circuit, which may be formed by a iron core having one or more permanent magnets. The magnetic circuit includes at least one plate or coating of electrically conductive material which is spaced from the coil and coextensive with the area of movement of the coil within the magnetic circuit. The electrically conductive material promotes rapid change of the coil current due to induced eddy currents and thus contributes to a low response time, or alternatively to a high response speed, of the drive apparatus, particularly with the use of a pulsed drive signal.Type: GrantFiled: July 15, 1985Date of Patent: August 21, 1990Assignee: Vacuumschmelze GmbHInventors: Ludwig Erd, Klaus Menzel

Patent number: 4439700Abstract: A magnetic drive system for generating linear movements, such as for driving a printing element in a high speed printer, has a bar-shaped armature with a coil comovable attached thereto, the coil and armature combination being seated in a yoke for longitudinal movement relative thereto. The yoke and armature consist primarily of low magnetic retentive material and at least one permanent magnet is disposed in the magnetic curcuit formed by the yoke and armature such that a magnetic flux is produced in the armature parallel to the longitudinal axis thereof. The coil is connected to a voltage source for operation such that current flow through the coil generates a field in the longitudinal direction of the armature which reinforces the attractive force of the magnetic field at one end of the armature while simultaneously reducing the force at the opposite end to thereby move the armature and coil together.Type: GrantFiled: February 25, 1982Date of Patent: March 27, 1984Assignee: Vacuumschmelze GmbHInventors: Klaus Menzel, Ludwig Erd, Marlene Marinescu

Patent number: 4019186Abstract: A motion pick-up in a non-mechanical printer to produce electric timing signals at instances of time at which given points of a path of motion are crossed includes a light transmissive rod arranged along the path of motion which is parallel to the line of print on a data carrier. The light transmissive rod has marks thereon, or associated therewith at the level of the given points and a laser beam which is split into sub-beams by an acousto-optical beam deflector provides a predetermined sub-beam which is deflected by a polygonal reflector and scanned thereby along the rod. The sub-beam is influenced by the marks in such a manner so as to cause light scattering and reflection through the rod so as to strike a photo-element and produce output signals which constitute electric timing signals. The rod may be glass or a synthetic material. The marks may be constituted by scratches on the rod.Type: GrantFiled: March 18, 1976Date of Patent: April 19, 1977Assignee: Siemens AktiengesellschaftInventors: Anton Dressen, Klaus Menzel

Patent number: 4000661Abstract: A mechanical quill and spindle drive mechanism is disclosed wherein the quill is advanced by means of a screw formed about its periphery and cooperating with a driven ball nut. The quill is received within a housing bore and accurately guided for longitudinal movement thereby by means of a sliding engagement with bore surfaces on either side of the nut. The spindle is carried by the quill throughout its longitudinal movement and is rotated by means of a splined drive shaft which maintains a rotative connection therewith by means of a splined connection therebetween.Type: GrantFiled: February 3, 1975Date of Patent: January 4, 1977Assignee: Bendix Machine Tool CorporationInventor: Klaus Menzel
