Title: Concatenated codes for spread spectrum communication
Inventor: O'FARRELL TIMOTHY
IPC: H04J13/00
Filed: 1998-12-18
Abstract: Spread spectrum communication techniques and applications using signature sequences are described to reduce the effects of certain transmission impairments such as co-channel interference, multiple access interference and intersymbol interference. Signature sequences with structured properties are obtained by generating cosets from a seed set of sequences, constructing a subset of sequences by concatenating the sequences of a coset and constructing a full set of sequences by concatenating the subsets of sequences.

Title: Composition and method for producing lubricating, germicide foam
Inventor: RICKETTS DAVID J
IPC: A61K9/00
Filed: 2000-09-27
Abstract: A skin cleaning, bacterial control, foam solution is provided, which enables a user to wash without requiring pre-wetting with water; this is followed by rinsing off the foam. The foam solution product is produced by mixing foaming and cleaning ingredients, active bacterial control ingredients, and water with a gas such as air, CO2, nitrogen, propellant, etc., to make the foam. The foam solution and method enables an improved coverage, better penetration, less time, and the least amount of active ingredients for controlling microorganisms when used for personal care washing. The lubricity of the water enables an easier wash, without the prior application of water; the wash is then followed by rinsing. The method for producing a foam surfactant suitable for a combined bovine teat dip and teat wash comprises air pressurization of a surfactant solution containing a germicide, disinfectant, biocide, etc., passing the air-surfactant mixture through a flow or line mixer to a foam holding cup adjacent the teat area and expanding the mixture to atmospheric in the holding cup to produce an adherent surfactant foam product with reduced run-off, which both protects and reduces infection of the teat, particularly at the teat canal and surrounding udder area.

Title: Artificial long terminal repeat vectors
Inventor: LIZARDI PAUL M
IPC: C12Q1/6844
Filed: 1999-09-15
Abstract: Disclosed are compositions and an in vitro method for cloning and/or amplification of nucleic acid sequences of interest. The method is based on strand displacement replication of the nucleic acid sequences by multiple priming on artificial long terminal repeat (ALTR) sequences appended to the ends of the nucleic acid molecule of interest. The nucleic acid molecules for cloning and amplification can be very long, up to 40 to 80 Kb or longer. In a preferred form of the method, a single primer is used to prime strand displacement replication at multiple sites in artificial long terminal repeat sequences, flanking a target nucleic acid, containing multiple tandem repeats of a primer complement sequence. Amplification proceeds by replication initiated at each primer and continuing through the target nucleic acid sequence. This nested replication of multiple copies significantly increases the amplification yield for extremely long nucleic acid molecules. By using a sufficient number of repeat units in the ALTRs, only a few rounds of replication are required to produce hundreds of thousands of copies of the nucleic acid sequence of interest. A preferred form of the disclosed method makes use of indexed artificial long terminal repeats that allow amplification and identification of specific nucleic acid fragments present in a mixture of nucleic acid fragments without requiring any knowledge of the sequence of the nucleic acid fragment.
