Patent CA-2288548-A1 (CA)
Inventor: CAMPBELL STEPHEN M
IPC: C08J7/043
Filed: 1999-11-04
Abstract: The present invention provides a composition comprising a low-molecular weight, amorphous polyalphaolefin layer and a water-sensitive substrate layer. Preferably, the polyalphaolefin comprises either a propylene-ethylene copolymer or an ethylene-butene copolymer. Polyalphaolefin coated water-dispersible films of the present invention may be advantageously employed in the preparation of a wide variety of products designed to be contacted with aqueous fluids.  Although the coated water-dispersible film of the present invention is particularly suited for personal care products, the coated water-dispersible film of the present invention may be advantageously employed in the preparation of a wide variety of consumer products other than personal care products. When the entire product is disposed of in water, the water-sensitive layer is wetted and weakens. Since the polyalphaolefin layer is already mechanically weak, hydraulic force from a toilet flow causes the composition to disperse into pieces small enough to flow through the toilet and beyond without clogging the water system.

Title: Method and apparatus for harvesting crops
Inventor: PARSON KENNETH ROSS
IPC: B07B7/08
Filed: 2000-06-09
Abstract: A method and system of harvesting crops involves cutting and threshing the crop, separating graff (a mixture of grain kernels, chaff, weed seeds, and other organic matter) from straw (plant stalks), and returning the straw to the field. This is preferably carried out in a harvesting unit of the pull type having a graff storage tank. The collected graff is moved to a stationary cleaning mill in a different location by means of a suitable vehicle such as a truck. Storage of the graff prior to cleaning is avoided and the cleaning mill, and preferably the harvesting unit and vehicle, are designed to make this possible. This avoids difficulties caused by the poor material flow of graff.      Various details of the equipment are also novel.
