Abstract: A magnetic metal deposition material contained in a hearth is heated and evaporated in a vacuum to form a flow of vapor, which is then ionized and converged toward a predetermined deposition surface of a flexible substrate. The flexible substrate is moved obliquely downwardly along a convex course by sliding contact with the curved surface of a fixed curved guiding body between a pair of guide rollers located at different heights above the hearth. The fixed curved guiding body communicates with a coolant source for cooling the substrate moving in contact therewith and may be provided with oscillators. Thus a thin film of the magnetic metal is deposited on the convex surface of the substrate.

It comprises a high-power light source for erasing the noise, which is provided between the aperture of the reservoir from which the stimulable phosphor sheets are taken up and the section at which the sheets are loaded into the cassettes.

Dry air is introduced beneath this partition and then flows along an upwardly directed channel (10) to an outlet (11) from which a deflector (12) directs it through the knitted fabric (13) to be dried and through the drums (8A, 8B) to a moist air outlet (5) disposed above the partition (9).

Abstract: The invention relates to a hand labeling apparatus for printing and applying adhesive labels on articles. The apparatus comprises a printer (21) held by a printer carrier (20) which is pivotable between an inoperative and an operative position. In the inoperative position the printer carrier (20) holds the printer (21) lifted off an adhesive label (11) lying on a printing platen (14), while in operative position it holds the printer (21) in contact with the adhesive label (11). By drive means (3, 30, 5) the printer carrier (20) can be moved from the inoperative into the operative position and can be automatically returned to the inoperative position under the influence of a resetting force. In order to prevent double imprints on the adhesive label the device includes retaining means (46, 60) which hold the printer carrier (20) in the operative position with a retaining force that is less strong than the resetting force.

Abstract: A method and apparatus for controlling a stepper motor and a disk drive is described for minimization of stepper motor oscillations for a single step, minimizing the time taken for the stepper motor to move between tracks for multi-track seeks, and reduction of angular hysteresis due to the mechanical and magnetic properties of the stepper motor construction.This control is achieved using a microprocessor-based circuit adapted to drive the stepper motor in accordance with predetermined programs. Oscillations of the stepper motor are damped by controlling, using one program, the current applied to the stepper motor during the last step of its motion by switching this current on and off within small predetermined time intervals. The time taken to move between tracks is controlled by another program in which the non-linear torque speed characteristics of a particular stepper motor are matched by a non-linear pulse rate which is determined by data held in the memory of the microprocessor circuit.

Abstract: An air switch comprises a switch body having a recess thereon and a switching member having an output connection port. The recess is connected to vacuum and pressure outlets through passages in the switch body. The vacuum passage is connected to a port on the wall of the recess while the pressure passage is connected to a partially circularly extending channel on the recess wall. The switching member is rotatably received in the recess and includes a radially extending channel on its inner wall. Positioning of the switching member in the vacuum or pressure modes places the member channel in fluid communication with either the vacuum port or the channel on the recess wall. When in the vacuum mode, the pressure channel is vented to the atmosphere and when in the pressure mode, the vacuum is similarly vented. When in the minimum pressure mode, a portion of the pressure is vented to the atmosphere although this pressure venting is reduced to zero when the switching member is in the maximum pressure mode.
