IPC: A01G9/10
Filed: 2000-05-29
Abstract: A plug tray for growing, planting and transplanting plants includes a surface member having a plurality of rows of inner cells and a pair of rows of outer cells.  Each row of outer cells is positioned proximate to an end of the surface member. A plurality of aeration apertures are formed in the surface member to thereby provide aeration to plants growing within the cells. The inner cells and outer cells are offset with respect to the major axis of the surface member to thereby provide increased strength and rigidity, allowing the tray to be manufactured using the relatively inexpensive process of thermoforming. The outer cells are configured such that the center-to-center distance between adjacent outer cells of a pair of plug trays placed end-to-end is substantially equal to the center-to-center distance between adjacent cells within a particular plug tray. The uniform center-to-center distance between outer cells of adjacent plug trays permits the plug tray to be used in a continuous automated process for planting and transplanting purpose. In an alternative preferred embodiment, a plug tray includes a plurality of rows of inner cells and a pair of rows of outer cells. Each inner cell and outer cell has four top edges, each of which is parallel to the opposing ends or opposing sides of the tray. Each outer cell is slightly smaller than each inner cell such that the center-to-center distance between adjacent plug trays is maintained.

Title: Apparatus for mixing and subsequent atomization of liquids
Inventor: FORBERT RAINALD
IPC: B01F3/08
Filed: 1998-11-19
Abstract: The invention relates to a device for producing a rapidly solidifying mixture from several liquid components and subsequently atomizing the solidifying mixture. The device comprises a mixing chamber (4), a liquid distributor (1', 7) and N equal drop-forming nozzles (9a, 9b) which are connected to the liquid distributor. The liquids to be mixed can be fed to the mixing chamber separately and the mixing chamber presents neither significant back-mixing in those areas in which reactions can occur nor significant dead spaces in the flow in these areas. The liquid distributor (1', 7) is connected to the mixing chamber and immediately distributes the mixture flow coming from the mixing chamber to the nozzles (9a, 9b) without significant back-mixing or dead spaces in said flow, so that the flow properties of the partial flows and their dwell times in the liquid distributor are the same for each such partial flow.
