  • Patent number: 5730773
    Abstract: The present invention is a device and method for selectively dispensing at least one target compound into a selected environment. A target compound is dissolved within an elastomer compound in a concentration that supersaturates the elastomer compound. The elastomer compound is then shaped into a selected form that is conducive to placement within the selected environment. The target compound within the elastomer compound begins to bloom to the surface of the elastomer compound where it is exposed to the surrounding environment. The bloom of the target compound into the surrounding environment continues until the concentration of the target compound within the elastomer compound reaches its saturation point. As such, the duration of the bloom of the target compound from the elastomer compound can be regulated by the concentration of the target compound within the elastomer compound, the volume of the elastomer compound and the surface area of the elastomer compound.

  • Patent number: 5720792
    Abstract: The invention concerns a high-grade, long-duration, organic fertilizer and a method of manufacturing it by the oxidative ammonolysis of industrial lignin. The fertilizer contains nitrogen in the form of ammonium compounds, normally hydrolyzable amides and more strongly bound organic nitrogen. The proportion of more strongly bound organic nitrogen is 55 to 85%, preferably 65 to 80%, relative to the total nitrogen content of the fertilizer. The manufacturing process uses industrial lignin precipitated under alkaline conditions from alkaline waste liquors, extracts or solutions. Preliminary tests have confirmed that this process gives a natural-like, high-grade, long-duration fertilizer similar to humus in character and with surprisingly good environmental compatibility.

  • Patent number: 5707416
    Abstract: The disclosure explains various methods of recovering byproduct heat from a compost stack while the compost stack is in a bacteria active stage. Several beneficial uses of the recovered heat are explained with specific examples given. Usage of the recovered heat to accelerate a bacteria active stage in a second compost stack provides for uniform degradation of the compostable material contained within the second compost stack. This results from reduction of areas within the compost stack which are at differing periods within the composting cycle. Alternatively, usage of the recovered heat to heat a building is explained. Various shapes of aeration plates are explained with examples given.

  • Patent number: 5702499
    Abstract: A batch process for the conversion of organic solid waste material containing cellulose and lignin through liquid thermophilic aerobic digestion comprises comminuting the organic solid waste material, adjusting the moisture content of the comminuted material to at least 90% parts by weight of water, mixing the comminuted material with a thermophilic aerobic micro-organism, adjusting the pH of the mixture to 5.5-7.5 and supplying heat and oxygen to the mixture to effect thermophilic aerobic digestion of the mixture. The thermophilic aerobic digestion of the mixture is terminated after the mixture has stabilized as a low nitrogen material but prior to digestion of the cellulose and lignin in the mixture, and the stabilized mixture is separated into solid and liquid fractions. The process includes the monitoring of parameters for determining the termination of digestion.

  • Patent number: 5698003
    Abstract: Improved solvent systems for the formulation of N-alkyl thiophosphoric triamide urease inhibitors. These formulations enable the preparation of stable concentrated solutions of N-alkyl thiophosphoric triamides for storage, transportation, and eventual impregnation onto solid urea containing fertilizers and incorporation into liquid urea containing fertilizer compositions. These formulations are comprised primarily of a solvent selected from the group consisting of glycols and glycol derivatives. Optionally, in addition to the glycol base solvent, the formulations can contain a co-solvent selected from the group consisting of liquid amides, 2-pyrrolidone and N-alkyl 2-pyrrolidones, and/or a nonionic surfactant selected from the group consisting of alkylaryl polyether alcohols. The presence of the co-solvent and/or surfactant has been found to impart desirable properties to the formulations under certain conditions.

  • Patent number: 5698004
    Abstract: Processes and structures for using calcium cyanamide fertilizer in a manner to greatly enhance its most effective soil treatment form prior to its application. Calcium cyanamide transformation structures have both fertilizing and pesticidal qualities; however, it is difficult to obtain uniform, efficient effectiveness from dry calcium cyanamide's liquid transformation structures. In the process of this invention, dry, dusty granules and fines of calcium cyanamide are placed directly into tanks of liquid for transformation or within biodegradable bags through which water can freely flow. The bags are submerged in a tank of water. The insoluble calcium and carbon components thereof remain as solid residuals within the bags. Hydrolysis occurs and the solution is biocidal and ready for immediate application. The solution can be sprayed or irrigated onto a targeted soil area with conventional dispersal equipment. The remaining non-dissolved material in the bags can be dispersed on and into the plant crop soil.

  • Patent number: 5695541
    Abstract: A process for producing a dried bacterial agricultural product having superior viability initially involves culturing (fermenting) a species of microorganism in a growth medium to form a culture. The culture containing the microorganism plus the growth medium is then mixed with a carrier. The resulting mixture is incubated for at least one day to increase the microorganism count in the mixture. The mixture is then air dried slowly for at least about one day so the moisture level in the microorganisms is gradually reduced to form the dried composition. The process may further include steps of milling and then coating seeds with the composition. An inoculant composition according to the invention, which may be made by the foregoing process, consists essentially of a clay carrier and at least 10.sup.9 viable bacteria per gram of the composition. Compositions containing biocidal microbes which combat insects, fungi or the like, and other useful microbes, such as growth promoting bacteria, may also be prepared.
