Patent CA-2396695-C (CA)
Inventor: WILLIAMSON STEVEN L
IPC: G01N22/00
Filed: 2000-12-28
Granted: 2010-04-13
Abstract: A system and method for using terahertz radiation to detect and monitor a substance undergoing a change in phase from a liquid phase to a solid phase or vice-versa is disclosed. By employing terahertz radiation in either the pulsed mode or in the continuous-wave (CW) mode, the system can non-invasively monitor these changes. The system uses the principle that matter in a liquid state will absorb and attenuate terahertz radiation to a larger degree than matter in a semisolid or solid state. Most terahertz radiation absorption occurs due to the rotational motions of molecules, i.e.  either whole molecules or groups of atoms rotating about molecular bonds.

Granted: 2011-05-31
Abstract: The present invention relates to a process for removing nitrogen oxides, sulfur dioxides and mercury from gas streams such as furnace or utility boiler flue gas streams, particularly those derived from coal-fired utility boilers. A stream containing relatively low concentration of ozone from an ozone concentrator is feed to a barrier discharge reactor. Nitrogen oxides and mercury in the flue gas are oxidized by oxygen and hydroxyl radicals formed in the reactor. The flue gas is then directed to a reactor duct along with the ozone at a greater concentration wherein the remaining nitrogen oxides and mercury in the gas stream will react with the ozone to form nitric acid, nitric acid precursors, mixtures thereof and mercuric oxide. These impurities can then be removed from the gas stream by use of an aqueous scrubber, a wet electrostatic precipitator, a dry scrubber or a semi-dry scrubber.

Abstract: A hog farrowing system for use in a cold environment includes a building providing protection from weather elements. The furrowing boxes have an entrance to permit free ingress and egress of female hogs but restrain the piglets. An alley is provided outside the boxes for the female hogs to defecate, urinate, and move to feed and water stations outside the boxes. The boxes have sides which define an inner chamber, a heat system, bedding for the female hogs to nest, and insulation covering an open top during cold environment conditions. The method utilizes the steps of promoting the female hog to utilize natural instincts, promoting the female hog to give birth to piglets close to the heat source, and protecting the piglets from crushing by using a creep area, anti-crush rods and anti-crush boards. The furrowing boxes can be modified for use in a warm season.

Abstract: A media server system includes a dispatcher and a set of processors either in the same physical system or in separate physical systems. The dispatcher receives the initial messages of respective session initiation dialogs from sources such as application servers. For each message, the dispatcher selects one of the processors to conduct the session initiation dialog and forwards the message to the selected processor using a port number uniquely associated with the processor and a switch fabric that routed the message to the processor associated with the modified port number. Upon receiving an initial session dialog message from the dispatcher, each processor creates a response message including the processor~s port identifier, and sends the response message to the application server that was the source of the initial message. Subsequent messages of the session initiation dialog are sent directly to the selected processor by the application server, bypassing the dispatcher.
