Title: Methods and compositions for enhancing the bioadhesive properties of polymers
Inventor: MATHIOWITZ EDITH
IPC: A61K9/50
Filed: 1997-01-24
Abstract: Methods and compositions are provided for enhancing the bioadhesive properties of polymers used in drug delivery devices. The bioadhesive properties of a polymer are enhanced by incorporating a metal compound into the polymer to enhance the ability of the polymer to adhere to a tissue surface such as a mucosal membrane. Metal compounds which enhance the bioadhesive properties of a polymer include water-insoluble metal compounds such as water-insoluble metal oxides, including oxides of calcium, iron, copper and zinc. The metal compounds can be incorporated within a wide range of polymers including proteins, polysaccharides and synthetic biocompatible polymers. In one embodiment, metal oxides can be incorporated within polymers used to form or coat drug delivery devices, such as microspheres, which contain a drug or diagnostic agent. The metal oxides can be provided in the form of a fine dispersion of particles on the surface of a polymer that coats or forms the devices, which enhances the ability of the devices to bind to mucosal membranes. The polymers, for example in the form of microspheres, have improved ability to adhere to mucosal membranes, and thus can be used to deliver a drug or diagnostic agent via any of a range of mucosal membrane surfaces including those of the gastrointestinal, respiratory, excretory and reproductive tracts.

Title: Communications system for monitoring the presence of animals in a natural feeding environment
Inventor: STEIN JOHN W
IPC: A01K11/00
Filed: 1997-09-12
Abstract: A communications system permits animal carried transponders (130), such as ear tag transponders, to be selectively addressed and detected when an animal is proximate to an unterminated wire (110). Addresses impressed on a frequency carrier on the unterminated wire (110) are coupled to an animal's transponder using a near field coupling, such as an electrical field coupling. When an animal's address is detected, the animal's transponder (130) responds with a data stream carrying a tone or with a signal of different frequency coupled to the unterminated wire. Coupling is enhanced by connecting signals to be transmitted and a receiver for signals to be received to the animal's body.  The unterminated wire (110) can be positioned along a feeding/water trough (120) in an agricultural environment to detect when a particular animal feeds or around a gate to detect when an animal passes through the gate.

Title: Apparatus and method for microwave curing of resins in engineered wood products
Inventor: HARRIS GEORGE M
IPC: B27N3/20
Filed: 1997-10-24
Abstract: An apparatus, system, and method, for using circular mode magnetic microwave energy to heat the interior regions of a work piece (12) of wood fiber and glue. The microwaves are generated and transmitted by a microwave system (38, 40, 54 and 56) as rectangular waveguide mode microwave energy, and are converted by mode converter to circular magnetic mode microwave energy. As circular magnetic mode microwave energy, the microwave energy passes through a work piece or billet (12) of material, is reflected on the other side and travels through the billet (12) a second time. Reflected microwave energy from the main reflected wave as well as reflections from other structures, surfaces and layers in the system travel back toward the microwave source (38). They are sensed at sensor sections (104), and a computer tuning system (144) causes capacitive probes to generate offsetting microwave reflections, which are opposite in phase and equal in magnitude to the sum of all of the reflected waves. These induced reflections cancel and negate the reflected microwaves, resulting in optimum utilization of microwave energy to heat the wood in the billet (12).
