Title: Catalytic burner apparatus for stirling engine
Inventor: ROYCHOUDHURY SUBIR
IPC: F02G1/055
Filed: 2010-11-17
Abstract: The invention provides an apparatus for generating heat and transferring the heat to a heater head of an external combustion engine, preferably, a Stirling engine. Fuel and air are introduced into a combustion chamber and mixed to form an air/fuel mixture.  The air/fuel mixture is combusted over a combustion catalyst positioned in physical contact with a heat spreader, which itself is positioned in physical contact with a heat acceptor surface. The heat acceptor surface is secured in thermal communication with the heater head. Depending upon the design of the heater head, heat flux from the heat acceptor surface into the heater head may occur radially or non-radially.

Patent CA-2724957-A1 (CA)
Inventor: HITZMAN DONALD O
IPC: C01B21/20
Filed: 2009-04-03
Abstract: An apparatus and method produces nitrate ions on-site from water, natural gas and air extracted in proximity to the apparatus. The apparatus generates nitrate ions and brings the nitrate ions into contact with an aqueous system. Hydrogen sulfide present in the aqueous system is removed and the production of hydrogen sulfide by sulfate- reducing bacteria (SRB) is eliminated by introducing into the system nitrate ions, whereby denitrifying microorganisms, using nitrate, outcompete the sulfate-reducing bacteria for the available carbon nutrients, thus preventing the SRB from producing hydrogen sulfide. Nitrate ions generated by the apparatus and added to the aqueous system which contains the denitrifying microorganisms can enhance oil recovery by means of-a microbial enhanced oil recovery mechanisms.

Abstract: Methods, systems and apparatuses are described for calculating a performance bond amount for a portfolio including interest rate swaps. A risk calculation module (or risk processor) may assist in the calculation. In some examples, values, such as swap (DV01) dollar values and volatility values, and adjustments/factors, such as calendar charge adjustments and liquidity charge minimums, may be used to enhance the margin calculation.  These values may be maintained and updated in various ways, including but not limited to, lookup tables, matrices, and other structures.

Title: Ecologically sensitive mud-gas containment system
Inventor: MATHENA HAROLD DEAN
IPC: E21B21/01
Filed: 2008-06-30
Abstract: This invention relates to an ecologically and environmentally friendly mud-gas containment system. Specifically, this invention relates to a mobile device that is capable of receiving waste gas and, in emergency situations, a volume of a mud--gas mixture from a drilling operation. The waste gas is communicated to a removable flare stack through a vent line. The mud-gas is received at a containment vessel. The impact of the mud-gas within the containment vessel separates the mud-gas into mud and waste gas. The mud is collected for recycling and/or environmentally sensitive disposal. The waste gas from the vessel is commu-nicated to the flare stack.Separate removal ports and conduits are used to remove any residual mud or mud-gas from the vent line and/or containment vessel. Excess mud or mud-gas is communicated to an overflow catch tank for removal. The entire assembly is mounted on a mobile skid sized for highway transportation.

Title: Cassette for use in a medication delivery flow sensor assembly and method of making the same
Inventor: ZIEGLER JOHN S
IPC: A61M5/168
Filed: 2009-05-21
Abstract: A disposable assembly for use with a sensor assembly comprises a body, a flow restricting element, and a fluid pressure membrane. The body has a lid portion and a base portion. The body defines a fluid flow passage that forms an inlet and an outlet. The flow restricting element is positioned in the fluid flow passage between the inlet and the outlet. The membrane is located between the lid and base portions along the fluid flow passage. A reinforcing structure, such as a ring or a rigid disk, is positioned between the fluid pressure membrane and the lid portion to provide increased resistance to pressure in the fluid flow passage. The ring or disk can be a separate component or formed on the membrane. The membrane thickness adjacent to sensor access openings in the lid portion can be increased for pressure resistance, too.

Abstract: The invention relates to a mechanism or drive (100) for a weapon which is characterized by only a limited acceleration of the breech (20) and a jerk- and recoil-free operation, thereby reducing the inertia force and the required power and increasing the repetition rate. The reduction of the required power also results in a reduction of braking power in the case of a quick stop. For this purpose, the rotational motion of preferably a motor (2) or the like is converted to a forward or reverse motion of the breech (20) using the Scotch yoke principle. In order to allow rest periods of the breech in the end positions, the rod (3) and the yoke (1) are arranged radially displaceable relative to each other so that the yoke radius changes when the yoke (1) is rotated. A control cam (6) radially guides the rod (3).

Abstract: A respiratory access assem-bly includes a distal plate having one port and cuff and an axially aligned proximal plate including a first port and first cuff and a second port and second cuff. The distal plate is configured to move relative to the proximal plate. The respiratory access as-sembly includes an actuator, which has a plurality of predetermined positions. When the actuator is positioned in a movement -enabling position, it permits movement of the plates while simultaneously blocking the first port of the proximal plate. When the ac-tuator is positioned in a first locked (open) position, it locks the plates together and aligns the port of the distal plate with the first port of the proximal plate and un-blocks the first port of the proximal plate so that an object, such as a suction catheter, may be positioned through the aligned ports. When the actuator is positioned in a second locked (open) position, it locks the plates together and aligns the port of the distal plate with the second port of the proximal plate and un-blocks the first port of the proximal plate so that an object may be positioned through the aligned ports. When the actuator is positioned in the third locked (closed) position, it locks the plates together such that the port of the distal plate is positioned between the first port and the second port or the proximal plate and all ports are out of align-ment with each other, such that all ports are blocked by a portion of one plate so that no object is moveable through any of the ports.
