Patent CA-2542981-A1 (CA)
Inventor: BROWN L WILLIAM
IPC: C10M145/36
Filed: 2004-10-20
Abstract: This invention describes a new refrigerant/lubricant combination for use in stationary and mobile refrigeration and air conditioning applications. In these applications, the refrigerant and lubricant must be soluble in each other (e.g., miscible) to ensure adequate lubricant circulation from the compressor, through the condenser, expansion device, and evaporator, and back to the compressor. Insufficient lubricant circulation will result in compressor failure. Low temperature solubility is particularly important to ensure lubricant flow through the cold evaporator. In addition, the lubricant and refrigerant combination should be stable in the presence of steel, and aluminum and copper containing metals. This invention describes the combination of refrigerant difluoroethane (R-152a) and polar, oxygenated lubricants, particular polyalkylene glycols (PAGs) and polyolesters (POEs) which may be used as a ~drop-in~ replacement for R-134a.

Abstract: A Non-Thermal Plasma (NTP) and Integral Catalyst System (ICS) is used to treat vent air containing Volatile Organic Compounds (VOC) and/or Halogenated Volatile Organic Compounds (HVOC), some of which may be odorous, and/or fine organic particulate (smoke) emissions to be released into the environment by commercial and/or industrial air venting. The system utilizes one or more dielectric barrier discharge (DBD) electrodes and dielectrics to develop one or more NTP fields so as to create sufficient Reactive Oxygen Species (ROS), hydroxyl species and other highly ionized molecules and atomic species in combination with catalytic functions so as to cause the oxidation and/or reduction of VOC's and/or HVOCs and/or fine organic particulate contaminants in the air streams to be decomposed to simpler, non pollutant, non odorous compounds that can be subsequently released into the environment. The system works by drawing atmospheric pressure air and/or gas, which may or may not be contaminated, through the NTP fields that are created by Dielectric Barrier Discharge (DBD) apparatus and mixing this air with the air and/or gas to be treated or by passing all air and/or gas to be treated through the DBD cells or any combination thereof. The DBD apparatus is designed with a catalyst material integral to the DBD cells and an optional additional catalyst immediately after the cells and is designed to pass large scale air flows typical of commercial or industrial processes.      When large volumes of gas and/or high VOC and/or HVOCs and/or contaminant load in combination with large gas volumes must be treated multiple units can be combined in parallel and/or series and/or series parallel to treat the gas.

Abstract: This invention is an insufflation system (56) that includes a first tube (62) that inserts into a patient's airway for providing a primary flow of breathing gas to such a patient. At least one insufflation catheter (66) is provided in or within the first tube for delivering a flow of insufflation gas to the patient. In one embodiment, the flow of insufflation gas is delivered in a first direction generally toward the patient's lungs and in a second direction generally opposite the first direction so that the flow in the second direction creates a negative stagnation pressure that substantially cancels out the positive stagnation pressure generated by flow in the first direction. In a second embodiment, an exhaust vent (70) is provided in the first tube for exhausting a flow of gas from the first tube at a rate that is equivalent to the rate at which the flow of insufflation gas is being delivered to the patient's airway, thereby preventing over-inflation of the patient's respiratory system. A third embodiment of the present invention involves a combination of the two embodiments discussed above.
