Title: Liquid application unit for air seeders
Inventor: BORSTMAYER DARREN
IPC: A01C7/06
Filed: 1999-06-02
Granted: 2007-08-21
Abstract: A liquid application unit for use on air seeders is provided which is cost-effective, has low maintenance and is highly reliable. This unit permits farmers to apply liquid substances, i.e. seed treatment substances to particulate material, namely seeds, just prior to the seed being inserted into the soil. The system uses an auger having two different pitches of flighting and/or different diameter flighting such that the volume available in between pitches of the flighting on the portion of the auger outboard of the orifice is greater than the volume available between the pitches inboard of the orifice. Chemicals are applied downstream of a sump area where the auger has either a larger pitch or larger diameter such that the volume available to the seed in the downstream area of the sump is greater. This will allow for better mixing action and minimize any effects on metering accuracy caused by build-up of chemicals on the flighting. In this device seed and chemicals are mixed by the rotation of the auger flighting within its cylinder.

Title: Isoflavone rich protein isolate and process for producing
Inventor: BRYAN BARBARA A
IPC: A23L1/30
Filed: 2000-04-28
Granted: 2003-12-30
Abstract: A process for providing an isoflavone rich protein isolate is provided, along with the isoflavone rich protein isolate produced thereby. A vegetable material containing protein and at least one isoflavone compound is extracted with an aqueous extractant having a pH above the isoelectric point of the protein, and preferably an alkaline pH. The protein and isoflavones are extracted into the extractant, and the extractant containing the protein and isoflavones is separated from insoluble vegetable protein materials to form a protein extract. The pH of the protein extract is adjusted to about the isoelectric point of the protein to precipitate the protein. The extract containing the precipitated protein is cooled to a temperature of from 30°F to 90°F, and then the protein is separated from the extract. Washing of the separated protein is avoided, or, is conducted with minimum amounts of water. The cool separation temperatures and the low wash conditions unexpectedly significantly increase the concentration of isoflavones recovered in the separated protein.

Title: Soft selection combining based on successive erasures of frequency band components in a communication system
Inventor: SUNDBERG CARL-ERIK WILHELM
IPC: H04L27/26
Filed: 2000-05-19
Granted: 2004-08-17
Abstract: Techniques for processing received information in a communication system, such that performance is significantly improved in the presence of certain types of interference. In an illustrative embodiment, first and second digital sidebands are transmitted on either side of an FM or AM host carrier signal in a hybrid in-band on-channel (HIBOC) digital audio broadcasting (DAB) system. The compressed digital audio information in the sidebands is encoded using an outer code, e.g., a cyclic redundancy code (CRC), and an inner code, e.g., a complementary punctured pair convolutional (CPPC) code. A receiver generates an error indicator based at least in part on a first decoding of the received information. The error indicator characterizes interference associated with at least one of the digital sidebands. The receiver then generates at least one alternative decoding of the received information if the error indicator has a designated characteristic. For example, the receiver may generate the alternative decoding by eliminating from consideration in the receiver decoding process a designated portion of at least one of the digital sidebands. The error indicator may be indicative of the presence or absence of a first adjacent interference signal of a particular level within a frequency band associated with one of the sidebands, and may be based on, e.g., a signal-to-noise ratio measurement generated from a pilot tone associated with a given sideband, and/or an error flag generated using the CRC outer code. Portions of the given sideband may be eliminated from consideration via successive erasures of sideband components, i.e., subbands, thereby resulting in an increase in the effective code rate of the inner code.
