Title: Breakaway hose coupling
Inventor: GHANDI AJIT
IPC: F16L29/00
Filed: 2010-05-19
Abstract: The invention is a breakaway coupling for use in hoses carrying a high pressure fluid in the form of a gas. The coupling comprises four primary parts. A first part is attached to a first hose and a second part is attached to a second hose. The first part includes a threaded portion that couples with a threaded nut in a third body by an inserting and twisting movement. Axial forces generated by fluid flowing through the coupling must generate sufficient pressures to overcome the torsion forces holding the first and third bodies together. The third body is held within a fourth body housing and is permitted movement in a clockwise direction but prevented from movement in a counter-clockwise direction by a sprag clutch between the third body and the fourth body. The fourth body is attached to the second body. The invention includes means to create a lateral movement of fluid within the coupling to minimize axial backpressure forces that encourage decoupling.

IPC: A61P31/00
Filed: 2011-05-09
Abstract: A microbial adherence inhibitor in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment of adherence of colony-forming immunogens in the respiratory tracts of host animals and humans. The inhibitor is made by inoculating female birds with the immunogen, harvesting the eggs which contain antibodies to the immunogen, and separating the yolk and albumin from the shells of the eggs. The yolk and albumin contents are administered to animals or human by distributing the contents directly or introducing the contents entrained in air. The adherence inhibiting material can be formulated for use in a variety of ways such as an oral spray or a nasal spray. These formulations can be effective to prevent or reduce respiratory illnesses in animals and humans.

Abstract: A system and method for dynamically selecting a communication protocol in an electronic toll collection system. A reader includes two or more multiprotocol transceivers operating under the control of a processor, each transceiver having a dedicated antenna. The system uses a fixed frame duration. A first communications protocol is used in a first portion of the fixed frame duration. If a response signal is not detected within the first portion, then the system ceases using the first communication protocol and instead uses the second communications protocol for the remainder of the fixed frame duration. The fixed frame duration is shorter than the sum of the durations normally used by the first and second communications protocol to conduct electronic toll transaction communications.

Filed: 2012-01-05
Abstract: A shape memory polymer is initially fabricated to a size where its peripheral dimension will be at least as large as the borehole wall in which it is to be deployed. After the initial manufacturing the material temperature is elevated above the transition temperature and the material is stretched on a mandrel to retain its inside dimension as its outside dimension is reduced to size that will allow running the seal to a desired subterranean location without failing the material during the stretching. The material is allowed to cool below the transition temperature to hold the new shape. The material on the mandrel is then secured to a tubular string and delivered to the desired location. Wellbore fluid at given temperature raises the material again above the transition temperature, which causes the material to revert to its originally manufactured shape.
