Abstract: The present application relates to an apparatus for inducing motion of particles of one or more substances and to methods of designing the same. The apparatus has a chamber (15) and utilises a supply means (A) and a removal means (B, C) to cyclically supply and remove one or more substances from the chamber. The supply and removal means are configured so as to tend to maximise the degree of transversality in the crossing of streamlines of first and second flow patterns within a working region of the chamber. They are also configured so as to tend to maximise the area over which the velocity function of said first and second flow patterns varies monotonically within the working region.

Abstract: A module for a printing composition delivery system of a printing device that is a separable unit from the printing composition delivery system is disclosed. An embodiment of the module includes a printing composition supply station connector, a printing member connector, and a flexible conduit. The printing composition supply station connector is releasably attached to a printing composition supply station of the printing composition delivery system and has a coupler fluidly connectable to a printing composition supply of the printing composition supply station. The printing member connector is releasably attached to the printing device and has a coupler fluidly connectable to the printing member. The flexible conduit includes a first end fluidly connected to the coupler of the printing composition supply station connector and a second end fluidly connected to the coupler of the printing member connector to supply printing composition from the printing composition supply to the printing member.

Abstract: A carriage drive system includes a carriage driven along a carriage path under a force generated by a drive motor. The driving force is coupled to the carriage by a drive belt. High frequency vibrations occurring in the drive belt are isolated from the carriage to improve print quality or scanning accuracy. Vibrations are introduced to the drive belt by the drive motor, the connection between the drive motor and the drive belt or from another source. High frequency decoupling is achieved using a spring connection which serves as a low pass filter of vibration frequencies. In addition, a linear encoder is included on the carriage for detecting carriage position. Such linear encoder samples carriage position at a rate fast enough to enable compensation for low frequency carriage vibrations.

Abstract: A shuttle-type printer includes a media feed assembly to controllably transfer a recording media through a printing station and a carriage operably mounted at the printing station to move bidirectionally across the media. The printer further includes means mechanically connected to the carriage and media feed assembly for simultaneously (1) moving the carriage and (2) indexing the media through the printing station, whereby the means includes a single motor. Accordingly, a single drive motor can accomplish both carriage motion and media advancement.
