Title: Treatment of water containing organic wastes with ammonium nitrate
Inventor: BURDENIUC JUAN JESUS
IPC: B01J3/00
Filed: 2001-07-10
Abstract: A single step wet oxidation process for treating wastewaters containing organic species, with or without heteroatoms, and anions of strong acids, e.g. sulfate or phosphate ion, or cations of strong bases, e.g., sodium, potassium or calcium ions, and which may contain ammonium ion and/or nitrate ion in addition to added ammonium ion and/or nitrate ion was developed which on thermal treatment near the critical temperature of water removes substantially all the COD and nitrogen through conversion to water, carbon dioxide or carbonate species, nitrogen gas and small amounts of nitrous oxide. Key to the success of the process is the balancing of all reducing species with an equivalent amount of oxidizing species and the balancing of all strong acid anions with strong base cations and including at least 0.06 acetate ion for moles of nitrate in the wet oxidation process.

Title: System for harvesting seed from a coniferous tree
Inventor: PRUFER FRED
IPC: A01D41/08
Filed: 2002-06-25
Abstract: A seed harvester pod and method are provided for harvesting seeds from the cones of a live, free - standing, coniferous tree. The pod comprises an open- sided conical frame, open at the top and bottom, supporting a permeable side wall, which may be netting. The netting is operative to allow penetration of sunlight, air and rain. However it will prevent the passage therethrough of airborne seeds released by the cones of the tree. The retained seeds deflect off the netting and drop into an interior, open-topped, annular trough supported by the frame at its base. The seeds are intercepted and collected by the trough. The pod can be lowered by a helicopter line onto the conical upper end of the tree, prior to cone maturation. After the cones have opened and the seeds have matured, released and become airborne, they are contained by the netting, drop and collect in the trough. The harvester is then later retrieved from the tree and the seeds are recovered.
