Abstract: The invention relates to an apparatus for helically winding tubes (R) with flat, uncorrugated strip material (B) which is drawn off from a roll of strip by the rotating tube (R) and is deformed immediately prior to being wound on to the tube (R) by a rolling process which is effected by a rolling ring (4), which surrounds the tube (R) and is driven in synchronism with the tube (R) by a rotary drive of the tube (R), and a rolling plate (8) rotating concomitantly in frictional engagement, the circumferential surface of which can be adjusted about an axis (9) extending transversely to the longitudinal axis (7) of the tube and is mounted to allow a feed motion relative to the rolling ring (4). In order to create a sufficiently large working space, the rolling ring (4) is rotatably mounted at an acute angle (6) to the longitudinal axis (7) of the tube and designed with a conical rolling surface (4a) for the rolling plate (8), which is likewise designed with a conical rolling surface (8a). The rolling gap resulting between the conical rolling surfaces (4a, 8a), which runs approximately at right angles and radially to the longitudinal axis (7) of the tube, is wedge-shaped with a gap width which decreases towards the outside. <IMAGE>

Abstract: The cleaning of an object, such as a circuit board (11), to remove residues therefrom is accomplished by spraying it with a terpene-based cleaning solvent (16,16′) while simultaneously maintaining the object in an environment substantially devoid of oxygen to avoid possible explosion of the mist formed by the cleaning solvent bouncing back from the object. Such spraying may be carried out in an enclosure (24) which is flooded with an inert gas such as nitrogen, or alternatively, the spraying may be carried out within a tank (14′) of the cleaning solvent (16′) below the level of the solvent in the tank.

Abstract: In an apparatus for reproducing information recorded in an opto-magnetic recording medium (29), a linearly polarized light beam is made incident upon the recording medium (29), a light beam reflected by the recording medium (29) is made incident upon a quarter wavelength plate (25) whose principal axis is inclined with respect to the polariza­tion direction of the incident linearly polarized light beam and is converted into one of two elliptically polarized light beams having major axes perpendicular to each other depending upon the direction of magnetization in the recording medium (29). The elliptically polarized light beam is made incident upon a polarization beam splitter (26) for separating major and minor axis components from each other, and the thus separated major and minor axis components are received by first and second photo­detectors (27a, 27b) respectively. Output signals from the photodetectors (27a, 27b) are supplied to a differential amplifier (28) to derive a difference therebetween representing a reproduced information signal. The information signal, which has a high C/N ratio, can be reproduced without being influenced by a phase difference caused by the opto-­magnetic recording medium and/or optical elements constituting the optical system of the apparatus.

Abstract: A sort accelerator is disclosed which uses a rebound sorter as a merger in which large numbers of records can be efficiently and rapidly sorted. The rebound sorter not only can sort a number of records but can be used to merge together previously sorted groups of records into larger sorted groups. A certain number of processing elements and record storage elements are used to simultaneously compare records. Depending on the sort chosen either a descending or ascending sort can be made. 
     The merging operation consists of an input phase, and a merge-up phase, an output phase, and a final merge phase. Successively larger strings of records are created until a final sorted string of records remains. Through various enhancements and associated circuitry the rebound sorter can sort and merge large numbers of records quickly and efficiently.

Abstract: A motion controller for the head carriage of an ink jet printer comprises a target signal generator providing constant velocity reference input to a servo loop controller. Also, two levels of current are applied to the drive motor during direction reversal, a lower one during deceleration of the carriage, and a higher one during acceleration of the carriage. The timing of the two current levels is determined by inputting a rectified velocity signal into a slope detector. A comparator converts the output of the slope detector into a binary signal for controlling the motor current level.

Abstract: A lens edging machine is numerically controlled by a computer to determine the rotation and displacement of a lens workpiece (16) with respect to an edging tool (10) in accordance with a lens shape stored in memory (60). The system continuously translates the lens workpiece (16) axially across the surface of the wheel (12, 14) to uniformly distribute wear across the wheel surface, reducing the need to dress the edging tool (10). The system compares the lens size with predetermined dimensions and compensates for any difference by automatically adjusting the lens trajectory during the edging of subsequent lens workpieces, permitting the edging tool to wear down without appreciable errors in lens size. The system controls the edging tool speed, the lens rotation rate, the lens axial feed velocity and the grinding force between the lens workpiece and the wheel at each discrete point during the entire lens edging operation to optimize production while preventing overheating of the lens workpiece. The optimum values for these parameters are empirically determined in a preparatory programmed trial and error learning process of the invention.
