Abstract: Dosing heads for apparatus for dispensing a defined amount of dry powder concurrently to a plurality of spaced apart dose receiving containers include a plurality of spaced apart elongate channels having a channel length with an upper end defining an entry orifice and a lower end defining an exit port. In use, the dosing heads are aligned with a dry powder bed residing above and in communication with the dosing head and at least one vibration source in communication with the dosing head channels configured to controllably apply a vibration flow signal. When the vibration flow signal is applied to the dosing head channels, dry powder from the dry powder bed flows through the elongate channels and out the exit port and when the flow signal is removed, dry powder does not flow through the dosing head elongate channels.

Abstract: Tubular dry powder feed systems in communication with a hopper of dry powder are configured with an in-line actuator that applies a flow vibration signal axially. The flow vibration signal can be a harmonic or non-harmonic signal, such as a sinusoidal, saw tooth, square wave or other signal and may be frequency or amplitude modulated.

Abstract: A paper transport simulates movement of a plurality of documents past the print station of a ink jet printer. The transport includes an arrangement for transporting a continuous paper web past the print station and a tachometer drive roller for contacting the tachometer wheel of the printer system. The transport further includes a document simulator wheel aligned with the photo-optical document detector of the printer system such that the movement of a succession of documents past the print station may be simulated while the printer system prints upon the continuous paper web.

Abstract: An ink jet printing apparatus for printing addresses on documents being transported along an independently operated conveyor. The printing apparatus includes a control console, a printing arm telescopically received within the console, and an ink jet printing head mounted on a carriage which is vertically movable within the printing arm. A tachometer wheel is mounted on the printing carriage for contacting a document being transported past the printing head and generating a tachometer signal in response thereto. A programmed microprocessor generates printing control signals in synchronism with the tachometer signal.
