20090189000 | Entangled cotton byproducts and biofiber hydraulic mulch- erosion control products, and the process for their manufacture - A method for making a hydraulically applied mulch using a natural biofiber material preferably comprising of 100% cotton byproduct or a mixture of cotton byproducts and other biomaterials selected such as, hay, grass, kenaf, straw, coconut, bamboo, hemp, bagasse and plant residue (cereal grains, rice, soybeans, grass seed, wood, sawdust, wood pulp, paper, or mixtures thereof). These fibers bear a natural waxy coating. The method includes the optional step of introducing the shredded biofiber composition into a first steaming chamber to stem the biofiber composition, followed by shredding the biofiber composition, and then introducing the shredded biofiber composition into a second steaming chamber to steam, break down and create porosity in the waxy coating of the fibers causing the fibers to become more hydrophilic. The biofibers are steamed followed by drying causing them to curl or physically deform. The shredded and steamed biofiber composition is then mixed to entangle the fibers, and the shredded, mixed and steamed biofiber composition is introduced into a drying chamber for drying, the resulting composition is then cooled and packaged, ready for mixing with water and spray application. The shredded, steamed and dried composition promotes entanglement of the fibers in a 3-dimensional matrix suitable for use as hydraulically applied mulch, and binding agents (tackifiers), dyes, rewetting agents, activators, and other additives may be added as desired. | 07-30-2009 |

20100147981 | CHEESE CRUMBLING DEVICE - An apparatus and method for crumbling a food product such as a block of cheese into irregularly shaped food particles. One embodiment of the apparatus consists of a chute-shaped housing that contains two opposing plates with a plurality of protrusions on their faces, where the plates are closer together towards the bottom of the chute. When food is inserted into the top of the chute and one of the plates is moved in an up-and-down motion, the protrusions on the opposing plates crumble the food into progressively smaller food particles until the crumbled particles drop through the gap between the bottoms of the plates and out the bottom of the chute. Other embodiments are described and shown. | 06-17-2010 |
20100243773 | HIGH THROUGHPUT, SEED SAMPLING AND COLLECTION SYSTEM AND METHOD - A system and method for preparing a sample of seeds or representative seed portions are provided. In various embodiments, the system and method include a force applying member and a seed container that includes at least one compartment containing a seed.
