Title: Variable rate flow divider
Inventor: ROBINSON JOHN R
IPC: B05B7/24
Filed: 1997-09-24
Abstract: A fluid distribution system is especially useful in agricultural apparatus for delivering liquid agricultural chemicals to agricultural fields. The system includes a flow divider with a cylindrical stator with a ring of collection chambers around the bottom of the stator and a rotor having a flow passage from the centre of the top end to the bottom end above the ring of collection chambers. The flow dividers may be cascaded to provide multiple outlets. The system may include plural liquid supplies and a mixer for mixing the liquids from the plural supplies to provide a desired blend upstream of the flow divider. It is preferred that the flow of each liquid can be varied to vary the blend. The system may also include a control that varies the blend according to requirements as distribution proceeds. This may include a recorded mapping of a field being treated and a position sensor, for example a global position sensor (GPS) for monitoring the position of the apparatus in the field. The liquid blend is then controlled according to the requirements of the field position.

Patent CA-2218002-A1 (CA)
Inventor: DUCKWORTH MARK R
IPC: H04N7/15
Filed: 1997-10-09
Abstract: A portable integrated videoconferencing unit has an integral housing in which an interior chamber houses an electronics board for performing video, audio, and communications processing.  Integrally mounted on the housing are a video camera and preferably a microphone array for providing directive audio processing.  The electronics board receives and processes video and audio outputs of the camera and microphone array respectively, and generates compressed video and audio outputs for transmission over the communications channel.  The electronics board also receives compressed video conferencing signals from the channel and processes those signals to generate the appropriate video and audio signals for connection to a video monitor.  Various elements are isolated from the microphones to reduce noise and vibration, and an answer bar can be mounted on the integrated unit to provide an easy known answer capability where an automatic answering mode is not desired.  The software of the unit can be upgraded during a videoconference call with an upgrade server.
