Abstract: A method of processing a communication apparatus includes putting the communication apparatus into a distribution channel for distribution via one or more intermediaries to a user of the communication apparatus, the user of which can forward the communication apparatus to a desired recipient. The communication apparatus includes a substrate and a communication element coupled to the substrate and is constructed of one or more materials that are a bio-technical nutrient. The communication apparatus is received from a recipient directly or via one or more intermediaries. The communication apparatus is processed to prepare a second communication apparatus for distribution to another user.

Abstract: Apparatus for dispensing includes a cartridge holder and main body having a generally circular central portion with three perpendicular flanges extending from one side and an elongate portion extending from the other side. A drive means on the elongate portion mounts a U-shaped drive rod for axial movement. Each flange includes a slot for receiving a pin formed on a replaceable generally cylindrical cartridge to act as a bayonet fitting. Viscous material is expelled from the held cartridge by driving the rod axially. A nozzle attachment has a primary section connected to the exit of the cartridge and includes a secondary section for holding a replaceable hardener tube, with the hardener being expelled by axial movement of a portion of the rod. The nozzle attachment includes a planar end surface for simple cleaning.
