Abstract: A multi-function condenser for an air conditioning system includes a first header, a second header, a plurality of tubes, and a conduit. The tubes extend in parallel relationship between the headers for establishing fluid communication between the first header and the second header. The second header includes a header portion and a receiver portion. A conduit extends into and out of and is surrounded by the receiver portion to define a space between the conduit and the receiver portion. Heat is transferred between hot refrigerant flowing in the receiver portion, the header portion, and cooler refrigerant flowing through the conduit as the refrigerant flows through the conduit independently of the refrigerant flowing in the space and in the header portion to increase an overall efficiency of the air conditioning system.

Abstract: A process for the synthesis of phosphorothioate oligonucleotides is provided which comprises assembling an oligonucleotide bound to a solid support in the presence of acetonitrile; prior to cleaving the oligonucleotide from the solid support removing the acetonitrile; and cleaving the oligonucleotide from the solid support. The process is particularly suited to the large scale synthesis of nucleotides. The acetonitrile may be removed from the solid support by one or both of drying and by washing with solvents. Preferred washing solvents comprise trialkylamines.

Abstract: A thermostatic expansion valve controls a flow of refrigerant. The valve includes a body defining a fluid chamber. A refrigerant inlet is defined within the body. The inlet communicates with the chamber such that the refrigerant can flow through the inlet and into the chamber. First and second outlets are defined within the body. The first outlet communicates with the chamber such that the refrigerant can flow from the chamber to an evaporator during normal and low refrigerant charge. The second outlet communicates with the chamber such that the refrigerant can flow from the chamber to a compressor during low charge. A moveable needle controls the flow of the refrigerant into and out of the body. A notch is defined within the needle such that, during low charge, the refrigerant that flows into the chamber can flow to the second outlet and to the compressor without flowing through the evaporator.

Abstract: A multi-function receiver attenuates pressure fluctuations of refrigerant flowing from an evaporator to a compressor in an air conditioning system. The receiver includes a body housing having an inlet for receiving the refrigerant from a condenser and an outlet for sending the refrigerant to the compressor. A cap housing covers the body housing. The receiver also includes first and second ports defined within the cap housing. The first port communicates with the evaporator for sending the refrigerant to the evaporator, and the second port communicates with the evaporator for receiving the refrigerant from the evaporator. An internal wall defines an outer and an inner cavity. The outer cavity communicates with the inlet for receiving the refrigerant from the condenser and with the first port for sending the refrigerant to the evaporator. The inner cavity communicates with the second port to receive the refrigerant from the evaporator and to attenuate the pressure fluctuations.

Abstract: A process is provided for making reduced fat, low fat or no-fat graham-based crackers and flour for the production thereof. The process for making the flour includes providing whole wheat berries having a moisture content of from about 15% by weight to about 20% by weight, radiating the berries with infrared (IR) energy, optionally maintaining the berries at an elevated temperature of from about 80° C. to about 110° C. for a period of time up to about one hour, and cooling, drying and comminuting the treated berries. The moisture content of the berries can be adjusted by moistening or tempering the berries prior to treatment with IR energy. The moisture content, optional tempering conditions, amount of irradiated IR energy, the elevated temperature, and the various treatment periods are sufficient to inactivate lipase and lipoxygenase in the berries yet insufficient to gelatinize more than about 20% of the starch in the berries.

Abstract: A concentric tubing apparatus prevents heat gain in an air conditioning system. The heat gain results from heat generated in an engine compartment of a vehicle. To accomplish this, the tubing apparatus includes a first and second refrigerant tubes. The first refrigerant tube is in fluid communication with a receiver and an evaporator of the air conditioning system to accommodate the flow of the refrigerant from the receiver to the evaporator, and the second refrigerant tube is in fluid communication with the receiver and the evaporator to accommodate the flow of the refrigerant from the evaporator to the receiver. The second refrigerant tube is disposed concentrically about the first refrigerant tube such that the second refrigerant tube insulates the refrigerant flowing in the first refrigerant tube from the heat generated in the engine compartment. Thus, heat gain in the refrigerant flowing in the first refrigerant tube to the evaporator is prevented.
