Title: Method and apparatus for the zoned placement of superabsorbent material
Inventor: HEATH MARK GORDON
IPC: A61F13/15
Filed: 1994-12-21
Granted: 2005-02-08
Abstract: The present invention provides an apparatus and method for forming a composite web having selected discrete pocket regions which are distributed on a carrier layer and contain high-absorbency material. The invention includes a pattern chamber having opposed side walls, an entrance end wall and an exit end wall. A particulate supplying mechanism provides particles of high-absorbency material into the pattern chamber, and a web supplying mechanism provides a gas permeable carrier layer. A foraminous forming mechanism moves the carrier layer through the pattern chamber, and the forming mechanism includes a pattern of openings which are formed therethrough and are arranged to provide for a selected pattern of the discrete pocket regions. A vacuum supplying mechanism provides a selected level of relatively low gas pressure at an underside region of the forming mechanism to produce a selected gas-flow through the carrier layer and the foraminous forming mechanism to form the pocket regions. A covering mechanism provides a layer of liquid-permeable covering material to sandwich said pocket regions of high-absorbency material between said carrier layer and said covering layer.

Title: Aminoureaformaldehyde fertilizer method and composition
Inventor: MOORE WILLIAM P
IPC: C05C9/02
Filed: 1993-12-30
Granted: 2000-07-25
Abstract: A new method of preparing a new aminoureaformaldehyde fertilizer composition which exhibits high cold water insoluble nitrogen (CWIN)levels and high Availability Indices (AI). The method utilizes the discoveries that ammonia compounds, usually ammonium salts, inhibit the urea-formaldehyde polymerization reaction and decrease the formation of hot water insoluble nitrogen (HWIN), and that the ammonium compounds take part in the reaction to form controlled release compounds which are both cold water soluble and insoluble. The process is carried out at elevated temperatures between 60 and 125 °F, so mat it may be completed in an older of magnitude less time than either the dilute or concentrated conventional commercial ureaform processes, requiring between 2 and 20 minutes for completion. In the process, between 3 and 25 per cent of the total nitrogen is supplied as ammonia nitrogen with the remainder from urea, respective formaldehyde to urea to ammonia mol ratio is 1.0, between 1.0 and 2.0 and between 0.05 and 1Ø The new fertilizer composition is produced directly as semi-dry granules, and exhibits urea conversions to CWIN  between 50 and 85 per cent with AIs higher drop 45.
