Abstract: This invention is for the purpose of feeding hay to livestock in a controlled and timed manner. It is comprised of a base, four sides. roof and floor and is able to contain one large round bale, or die equivalent in loose hay or square bales. Three gate assemblies are used, consisting of a double gate in which an outer feed gate moves up and down and a fixed inner gate remains stationary. Operation of the feed gates is controlled by a programmable timer, which in conjunction with a 12VDC air system, raises and lowers the feed gates. Power is provided by either 110VAC or a completely self-contained 12VDC system utilizing solar panels. The loading of feed into this invention is accomplished by opening one of the gate assemblies, which are hinged on one side, to allow the whole gate assembly to swing open to facilitate loading and cleaning.

Title: Organic recycling with metal addition
Inventor: DAHMS GARY L
IPC: C05F1/00
Filed: 2004-05-27
Abstract: The invention is directed to methods for producing a granular nitrogen fertilizer from an organic material comprising adding a metallic salt to said organic material to form a slurry. Preferably the organic material comprises dewatered biosolids and contains water from a scrubber. Metallic salts that can be used comprise a salt of iron, zinc, or a mixture thereof. Preferred iron salts comprises ferric sulfate or ferric oxide, and preferred zinc salts comprises zinc sulfate or zinc oxide. Preferably, the metallic salt is mixed with an acid such as sulfuric acid to form an acidified metal salt. Slurry pH  ranges from approximately 2-2.5. The acidified metal salt is added to the organic material in sufficient quantity to lower viscosity of the slurry such that the resulting fluid does not hinder fluid flow during operation. When the metallic salt comprises acidified ferric sulfate or ferrous sulfate, sufficient iron can be present to produce a fertilizer product with 0.1 weight percent to 10 weight percent iron sulfate calculated on a dry weight basis.  The invention is also directed to fertilizer products made by the methods of the invention. Preferred products are granules and the metallic salt increases product hardness. Fertilizer granules preferably contain metal that is bioavailable to a plant when used as a fertilizer. Solubility of the metal of the product in water is enhanced, and the product is low staining.

Abstract: An adhesive layer forming method capable of forming an adhesive layer to a specified thickness in a step for forming the adhesive layer on the surface of a member to be treated for forming a film containing powder in the member to be treated. An adhesive layer forming medium (m1) coated with an adhesive substance is collided with the member to be treated (W) to move the adhesive substance from the adhesive layer forming medium (ml) to the member to be treated (W) to form the adhesive layer on the member to be treated (W). The adhesive layer formed on the member to be treated can be formed to the specified thickness by adjusting the thickness of the adhesive substance (amount of the adhesive substance held by each of the adhesive layer forming medium) applied onto the adhesive layer forming medium. Thus, a finally formed powder film can also be formed in a specified thickness.

Title: Multiple azimuth control of vertical hydraulic fractures in unconsolidated and weakly cemented sediments
Inventor: HOCKING GRANT
IPC: E21B43/26
Filed: 2004-12-28
Abstract: The invention is a method and apparatus for initiating multiple azimuth controlled vertical hydraulic fractures in unconsolidated and weakly cemented sediments from a single bore hole to control the fracture initiation and propagation of hydraulic fractures at differing azimuths. The multiple azimuth vertical fractures enable greater yield and increased recovery of petroleum fluids from the formation. An injection casing with multiple fracture initiation sections is inserted and grouted into a bore hole. A fracture fluid carrying a proppant is injected into the injection casing and opens fracture initiation sections to dilate the formation in a direction orthogonal to the first fracture azimuth plane. Following completion of the first fracture injection, the fracture fluid is injected into the injection casing and opens a set of second and subsequent fracture initiation sections dilating the formation and initiating and propagating a second and subsequent vertical hydraulic fractures at different azimuths to the first and subsequent earlier installed fractures.
