Abstract: Apparatus for controlling the placement of seeds deposited by a seed placement device in a furrow. The apparatus comprise a guide member connected to the seed placement device adjacent an exit of the seeds from the placement device adapted to urge seeds discharged from the exit toward a sidewall of the furrow. The guide member of the present invention acts to stop seeds from bouncing off the sidewalls of the furrow and into the centre of the furrow. The guide member organizes the seeds to create one or more seed rows where the seeds are optimally positioned and prevents seeds from ending up in the middle of the furrow. If a fertilizer row is present below the seed furrow, this prevents damage to the seeds by preventing them from being too close to the fertilizer. The guide member also stops the seeds from being swept back into the central region of the furrow with the loose soil that flows back into this area after the knife implement has passed.

Abstract: Anonymous voice communication between a first station and a second station is facilitated by providing an interface that allows input of a transaction specification from at least one of the first and second stations. A reference code associated with the transaction is generated, there being a defined relationship between the reference code and the address of the second station for voice communication. The reference code is supplied to the first station, and a voice communication request and the reference code are received from the first station. The reference code is used to recover said address and a channel for voice communication is opened between said first and second stations. Voice communication can thereby be established between the first and second stations without providing the address of the second station to the first station.
