  • Patent number: 5756540
    Abstract: In accordance with the present invention, there are provided methods for the in vivo reduction of nitric oxide levels in a mammalian subject. In contrast to the inhibitory approach described in the prior art (i.e., wherein the function of the enzymes responsible for nitric oxide production is inhibited), the present invention employs a scavenging approach whereby overproduced nitric oxide is bound in vivo to a suitable nitric oxide scavenger. The resulting complex renders the nitric oxide harmless, and is eventually excreted in the urine of the host. Further in accordance with the present invention, there are provided compositions and formulations useful for carrying out the above-described methods. An exemplary nitric oxide scavenger contemplated for use in the practice of the present invention is a dithiocarbamate-ferrous iron complex. The present invention relates to methods for reducing in vivo levels of .multidot.NO as a means of treating subjects afflicted with inflammatory and/or infectious disease.

  • Patent number: 5723329
    Abstract: The present invention relates to novel receptor polypeptides, which, upon interaction with certain ligands, or activation by certain compounds, modulate transcription of certain genes by binding to cognate response elements associated with promoters of such genes. The novel receptors of the invention modulate transcription in the presence of retinoid compounds. The receptors of the present invention differ significantly from known retinoic acid receptors, in protein primary sequence and in responsiveness to exposure to various retinoids. The invention provides DNAs encoding the novel receptors, expression vectors for expression of the receptors, cells transformed with such expression vectors, cells co-transformed with such expression vectors and with reporter vectors to monitor modulation of transcription by the receptors, and methods of using such co-transformed cells in screening for compounds which are capable, directly or indirectly, of activating the receptors.

  • Patent number: 5661384
    Abstract: This disclosure provides a motor control system and method that is preferably applied to cargo power drive units. Power is supplied to a motor having one or more windings and a thermocouple that is embedded in the motor windings. The thermocouple provides an electronic signal from which both motor temperature and rate of temperature change are derived. A motor control circuit uses these values to determine if a jam condition has occurred (as represented by improper temperature rise) or whether critical overheating is occurring. If so, the motor control circuit causes a power switch to disconnect power from one or more PDUs in the subject bank of PDUs. Power is temporarily disabled, until a cargo operator releases a joy stick control to a neutral position and then attempts to use it again.

  • Patent number: 5659465
    Abstract: An electrical power conversion system that supplies the maximum available output power from a power source such as a solar array to a plurality of loads such as rechargeable batteries. The output power of the solar array peaks at an optimum current that is less than is maximum available output current. The system includes a controller and a plurality of dc-to-dc converters that charge the batteries. The controller monitors the solar array's output power and adjusts the battery charging by generating a current control signal that tracks a peak of the solar array's available output power and sets a current limit such that the combined current draw of the plurality of dc-to-dc converters is substantially equal to the solar array's optimum current at which it provides its maximum available power. The electrical power and control signals are transmitted from the power source and controller to the power converters on three bus bars, including a power bus, a control bus, and a common bus.

  • Patent number: 5635235
    Abstract: Masa handling methods for the continuous processing of masa type dough in conjunction with commonly available feed processing equipment, such as a masa extruder, an oven, or cooling apparatus. One masa handling method includes a masa separator having a pair of opposed, endless belt conveyors having facing surfaces spaced apart to receive a generally continuous masa stream output from a nozzle on the masa extruder. When the masa stream moves between the conveyors, it is gripped by their facing surfaces and moved away from the nozzle, causing the masa to be separated into individual pieces, or logs. The masa handling method can also include feeding the masa to masa hoppers fed by at least two endless belt conveyors arranged in upstream and downstream positions relative to each other.

  • Patent number: 5632142
    Abstract: This disclosure provides a stationary gas turbine power system that develops a reduced back pressure for the gas turbine engine and thus greater efficiency. An enclosed ejector is positioned downstream of the engine's exhaust plane, and means such as a downstream diffuser cause the exhaust stream to entrain air from the ejector enclosure, by natural pumping action, so as to develop a sub-atmospheric pressure within that enclosure and thus at the engine's exhaust plane. This provides substantially improved engine efficiency. The diffuser recovers the static pressure to a level sufficient to drive any downstream devices.

  • Patent number: 5632555
    Abstract: An improved prediction-type medical thermometer that provides an accurate estimate of a patient's temperature in substantially reduced time as compared to prior thermometers of this kind. This improved performance is achieved by using a special hollow probe tip having a low heat capacity and incorporating a resistive heater that is actuated only upon removal of the probe from a base housing. The heater regulates the temperature to a value of about F. After the probe is applied to the patient, a microprocessor repeatedly samples the thermistor and estimates the patient's temperature based on the successive samples. If a predetermined number of successive temperature estimates lie within a predetermined error range, the sampling is terminated and the most recent estimate is displayed as the patient's temperature.

  • Patent number: 5631129
    Abstract: This invention relates to the use of functional reporter molecules in the detection and measurement of RNA sequences in a sample, as a determination, for example, of pathogenic disease existence or potential. The invention is predicated on the utilization of nucleotide sequences, one having a probe sequence linked to a sequence capable of initiating replication by an RNA-dependent RNA polymerase. The other is capable of hybridizing to a strand separated from the extension product of the first nucleotide sequence after hybridization to a specific target sequence. The extension product of the second hybridized nucleotide sequence serves as a template source for autocatalytic replication by the RNA-dependent RNA polymerase. The replication products are detected as a means for detection of nucleic acid sequences.

  • Patent number: 5627338
    Abstract: A system and method for launching projectiles, such as fireworks projectiles, which explode in the air into a pyrotechnic display. The projectile includes a shell constructed from a binding agent and an explosive additive which explodes the shell into small particles. The explosive additive, which may be nitrocellulose, causes the exploded particles to be rapidly burned and consumed to form lightweight, inert flakes that fall harmlessly to the ground. The projectile is aimed and launched by a launcher to rapidly expel the projectile from a launching tube. Once in the air at a predetermined location in the sky, a fuse inside the projectile operates to detonate the projectile into its intended pyrotechnic display. The fuse is extremely accurate and enables detonation of the projectile at precise altitudes. An electronic control system controls launching and detonation of the projectiles in a precise and repeatable manner.
