Abstract: A diffuser assembly for a heating, ventilating, and air conditioning (HVAC) system includes a housing having an outer frame and an inner frame disposed within the outer frame. The outer frame includes an inlet configured to receive an air flow. The inner frame forms a first flow path for the air flow through the housing between the outer frame and the inner frame. The inner frame defines a second flow path for the air flow through the inner frame. The diffuser assembly also includes a damper assembly configured to transition between a first configuration to enable discharge of the air flow from the housing via the first flow path and a second configuration to enable discharge of the air flow from the housing via the second flow path.

Abstract: The instant invention has developed viral vectors encoding a mutant bacterial cytosine deaminase (bCD) gene, which have a higher affinity for cytosine than wild type bCD (bCDwt). The purpose of the present invention was to evaluate cytotoxicity in vitro and therapeutic efficacy in vivo of these vectors in combination with the prodrug 5-FC and ionizing radiation against human glioma. The present study demonstrates that infection with the viral vector expressing the mutant cytosine deaminase gene resulted in increased 5-FC-mediated cell killing, compared with vectors expressing the wild-type gene. Furthermore, a significant increase in cytotoxicity following infection with viral vector expressing the mutant cytosine deaminase gene and radiation treatment of glioma cells in vitro was demonstrated as compared to infection with viral vector expressing the wild-type gene.

Abstract: Described is a constitutive inward Na+ currents found in a variety of human cancers. The constitutive inward Na+ current plays a role in increased cellular proliferation, cellular migration and volume regulation. The inward current is mediated, at least in part, by AISC-containing Na+ channels. In addition, an inhibitor of the inward current, the PcTX1 peptide, is described. Also provided are methods for screening compounds to inhibit the inward Na+ current, methods for screening for tumors expressing the inward Na+ current and methods for treating tumors expressing the inward Na+ current.

Abstract: A downrigger including a downrigger line and weight supported from a motor powered reel associated with a fishing line and fishing rod with a releasable interconnection between the downrigger line and fishing line so that when the bait connected with the fishing line is taken by a fish, the fishing line will separate from the downrigger line to enable a fisherman to play and reel in the fish in a well known manner. The motor powered reel can pivot between an outboard fishing position, an idle position above a boat cover board or gunwale and an inboard position which enables the reel, motor and associated components of the downrigger to be attached to or removed from the boat. Power is supplied to the powered reel only when the downrigger is in the outboard fishing position. The powered downrigger unit includes a removable cover for the reel, motor and other drive components to prevent accidental contact with these components.

Abstract: Apparatus situated in a borehole traversing an earth formation is protected from closing of the borehole by being encased in an inflatable device. Surface equipment inflates and maintains the inflatable device at a sufficient pressure so as to prevent the earth formation from closing in and contacting the apparatus. A pressure sensor senses the maintenance pressure and provides a corresponding signal. An alarm circuit provides an alarm when the pressure decreases below the sufficient maintenance pressure level.

Abstract: A wide dynamic range automatic gain ranging amplifier system includes an amplifier which receives an analog input signal and amplifies the received analog input signal in accordance with gain control signals to provide an amplified signal. A network connected to the amplifier also receives the analog input signal and provides the gain control signals corresponding to a desired gain for the amplifier in accordance with the received input signal and also provides gain status signals representative of the gain associated with the amplified signal.

Abstract: A characterization factor monitor samples oil and provides a signal K corresponding to the characterization factor of the oil. Signal K may be used as a control signal or may be displayed by conventional display means to an operator. The monitor includes a refractometer and a flash point analyzer sampling the oil and providing signals RIt and F corresponding to the refractive index of the oil and to the flash point in degrees F of the oil, respectively. A temperature sensor senses the temperature of the oil and provides a signal T representative thereof. An output circuit connected to the refractometer, to the flash point analyzer and to the temperature sensor provides signal K in accordance with signals F, RIt and T.
