Title: Hydrodynamic and reinforced catamaran hull design
Inventor: SCHULTE MARK
IPC: B63B1/20
Filed: 1999-02-24
Abstract: An air propelled boat. It is provided with a pair of catamaran hulls, each having a unique catamaran hull design particularly adaptable for travel over land, water, ice or snow. Each catamaran hull has a pair of centered concave flutes extending from the aft end of the body to the forward end of the nose. At the nose end, the flutes are reduced in concavity and inclined longitudinally and laterally. Both inclinations are reduced in slope forward. The flutes guide water outward and under the hull and move the water hull contact aft. This decreases hull drag and increases lift. The hull bottoms are formed into a central longitudinal support flat which is flanked by parallel outboard support flats. The undersurface of a catamaran hull is covered by an ultra-high molecular weight plastic profile to reduce friction when traveling over a solid supporting surface. The catamaran hulls are foam filled for rigidity.

Patent CA-2267421-A1 (CA)
Inventor: COLEMAN MARILYN A
IPC: A61P31/04
Filed: 1997-10-02
Abstract: Broadly, the present invention is directed to the use of egg antibody preparations in the treatment of systemic disease in human and non-human mammals. IgY antibodies are first obtained from the egg of a domestic fowl hen which has been actively immunized against said one or more pathogenic organisms by injection with an immunogen containing immunogenic determinants specific to elicit such antibodies. The antibodies are then administered orally to a mammal suffering from an infectious systemic disease caused or exacerbated by such pathogenic organism or organisms. This invention, thus, is capable of providing passive immunity to patients with failing immunity or that are immunologically naive. It is unnecessary to separate the antibodies from the egg yolk, so processing and administration are convenient and inexpensive. Antibody produced from egg yolks of hens immunized against specific antigens are effective in controlling noxious agents, whether viral, bacterial, fungal, protozoal, toxins, enzymes, inflammatory mediators, prostaglandins, leukotrienes, thromboxines and other messenger molecules, sarcomas or carcinomas, not only within the bowel but also in tissues remote thereto. The immunogenic determinant may comprise only a specific portion of the pathogenic organism, e.g., the loop or coat of a virus or the fimbria of a piliated bacterium. The method of this invention has been shown to be efficacious in the treatment of AIDS in human beings, TNF mediated septic shock in mice, and in lowering somatic cell count in dairy cattle.

Title: Apparatus for and method of using optical interference of light propagating through an optical fiber loop
Inventor: NIIMI SHINICHI
IPC: G01H9/00
Filed: 1999-04-27
Abstract: A signal/vibration detecting technique employs a simple structure to identify a target optical fiber among many and carry out a bidirectional conversation through the target optical fiber.      First ends of optical fibers (202A, 202B), one of which is a target optical fiber, are connected to an optical transceiver (201). Second ends of the optical fibers are connected to each other to form a loop. A local unit (203) is installed at the loop. The local unit vibrates the loop, and the optical transceiver emits lights so that the lights are oppositely propagated through the loop. The propagated lights are coupled together so that they interfere with each other.      In the intensity of the interfering lights, a change corresponding to the vibration is detected to identify the target optical fiber. Once the target optical fiber is identified, it is used to carry out a conversation between the optical transceiver and the local unit.
