摘要： A system for transmitting rotational motion between a driving element and a driven element comprises a driving element that is coupled to a torque input that causes the driving element to rotate about a drive axis. The driving element comprises a first magnetic element. A driven element is configured to rotate about a driven axis. The driven element comprises a second magnetic element. Both the first magnetic element and second magnetic element are susceptible to a magnetic field, and at least one of the first and second magnetic element produces a magnetic field. A magnetic interaction between the first magnetic element and the second magnetic element couples the rotational motion of the driving element and the rotational motion of the driven element. The driving and driven elements are coupled at a predetermined rotational orientation with respect to each other.

摘要： An apparatus for printing on cylindrical objects (31) comprises a plurality of printheads (32); and at least one holding device movable relative to the printheads (32) such that, in use, the holding device moves the object between the printheads. The path of the at least one holding device comprises a plurality of vertical sections (34) which are horizontally offset from one another. Each vertical section (34) comprises at least two identically orientated printheads (32) arranged such that they are vertically displaced from one another, with one directly above the others. The at least one holding device moves the object (31) between the at least two printheads (32) such that part or all of its path between the printheads is vertical.

摘要： A method of printing a two-dimensional bit-mapped image having a number of pixels per row for printing using a plurality of overlapping printheads or a printhead or printheads indexed through overlapping positions, the or each printhead having a row of ejection channels, each ejection channel having associated ejection electrodes, the method comprising: applying a voltage to the ejection channels sufficient to cause concentration of particles in the printing fluid at the ejection channels, applying voltage pulses of respective predetermined amplitude and/or duration, as determined by respective image pixel bit values, to the electrodes of the selected ejection channels in order to cause volumes of printing fluid to be ejected from selected ejection channels of the overlapping printheads, thereby forming a pixel of a predetermined optical density, adjusting, for each row of the image, the values of the voltage pulses to be applied to the overlapping printheads to form pixels printed by overlapped ejection channels in dependence on the position of the pixel within an overlapped region of the printheads and in dependence on the predetermined optical density of the pixel, wherein, for at least one pixel in the overlapped region, the total volume of ink ejected by the overlapped channels is greater than that required if that pixel were formed by a single ejection channel.

摘要： A maintenance cap is provided for in-situ attachment to a printhead of printing apparatus. The maintenance cap comprises a housing defining at least one chamber for receiving a liquid. An opening in the housing provides a path for the liquid to pass from the chamber into a portion of the printhead when the maintenance cap is engaged with the printhead. The maintenance cap also includes a seal disposed around the opening for engagement with the printhead. A transducer coupled to the housing is used to generate ultrasound acoustic waves in the liquid contained in the chamber and printhead so as to clean the printhead.

摘要： The present disclosure provides an apparatus for handling objects. The apparatus comprises a carrying device (104) that is configured to move along a track (102). A handling device (224) is adapted to hold an object (108) and is mounted to the carrying device (104) such that it is rotatable with respect to the carrying device about a handling axis (226). A drive device (310) is disposed at a position along the track (102) and configured to produce a torque around a drive axis. The carrying device (104) can be moved along the track (102) in a direction perpendicular to the drive axis into and out of a drive position. In the drive position, the handling axis (226) of the handling device (224) is in substantial alignment with the drive axis of the drive device (310) whereupon the drive device induces a torque in the handling device (224) causing the handling device to rotate, thereby causing the object (108) held by the handling device to rotate.

摘要： A method of printing a two-dimensional bit-mapped image having a number of pixels per row for printing is disclosed. The method and apparatus use either a plurality of overlapping printheads (300) or a printhead or plurality of printheads indexed through overlapping positions. The or each printhead has a row of ejection channels (301), each of which has associated ejection electrodes to which a voltage is applied to cause particulate concentrations to be formed from within a body of printing fluid. In order to cause volumes of charged particulate concentrations of one of a number of predetermined volume sizes to be ejected as printed droplets from selected ejection channels of the overlapping printheads, voltage pulses (VE) of respective predetermined amplitude and duration, as determined by respective image pixel bit values, are applied to the electrodes of the selected ejection channels. For each row of the image, the values of the voltage pulses to be applied to the overlapping printheads to form pixels printed by overlapped ejection channels are adjusted in dependence on the position of the pixel within an overlapped region of the printheads and in dependence on the predetermined volume size of the pixel.
