  • Publication number: 20210106935
    Abstract: The current technology relates to substrate treatments, treated substrates, and filters. Treated substrates can have a treated surface that defines a pattern and/or gradient among untreated surface areas. A treated surface area can have a higher roll off angle for a 50 ?L water droplet when the surface is immersed in toluene that the untreated surface areas. Substrates can be treated by, for example, exposing a substrate surface and/or fibers to ultraviolet (UV) radiation. UV radiation can be applied to surfaces via a mask, lens, waveguide, reflector, as examples. UV radiation can be applied to surfaces at varying intensities, which can create a treatment gradient.

  • Publication number: 20110106775
    Abstract: In a large scale data repository, a single logical view of multiple versions of the same data is presented. In order to determine which data versions are equivalent without comparing each pair of entries in the database, the database entries are clustered with a clustering algorithm and then comparisons between entries are made only between the entries in each cluster. Once a set of entries has been determined to be equivalent, a composite master entry is constructed from those entries in the set that contain preferred metadata and the composite master entry is made available for searches and display to the user.

  • Patent number: 5126324
    Abstract: A method is disclosed for enhancing growth of a mammal by administration of a combination of effective amounts of IGF-I and GH so as to enhance the growth of the mammal over the enhancement in growth achieved using either IGF-I or GH alone in an amount equal to that used for either IGF-I or GH, respectively, in the combination. Preferably, the mammal is a child, the IGF-I is native-sequence, mature human IGF-I or human brain IGF-I, and the GH is native-sequence, mature human GH with or without a terminal methionine. In another preferred embodiment, the mammal is a non-human animal of economic importance such as a cow or pig.

  • Patent number: 4684081
    Abstract: The multifunction power system is a combination auxiliary power unit, environmental control system, engine start system, and emergency power system for an aircraft. The system is essentially a four-wheel auxiliary power unit comprising two compressors driven by one turbine by means of a common shaft and in addition a free turbine. The pressurized flow from the second compressor can be directed to parallel combustors and thereafter to the two turbines. A starter-generator and motor are coupled to the compressor drive shaft and the free turbine is used to power a generator and for engine starting. Ducts, heat exchangers, valves, etc., are so arranged as to provide the four functions by proper selection and routing of air.

  • Patent number: 4587436
    Abstract: The invention is a two-level power system for electrically powered aircraft sub-systems. An aircraft engine (2) drives a three phase generator (30) at a variable speed. The output of generator (30) is primary variable-voltage/variable-frequency (VV-VF) power which is utilized by various aircraft subsystems. A portion of the primary VV-VF power is converted to constant voltage-constant frequency (CV-CF) power by an inverter (31) which includes front end rectification. The CV-CF power is then available to selected aircraft subsystems while portions of the CV-CF power are converted by rectifier (32) and transformer-rectifier (33) into 270 vdc and 28 vdc power, respectively, which power is also then available to aircraft sub-systems.

  • Patent number: 4575027
    Abstract: An actuator system for controlling the position of an aerodynamic control surface of an aircraft is disclosed. The actuator system (10) comprises a rotary actuator (12) rotatably mounted to the aircraft structure (20) with the actuator having an output member (22) adapted to be coupled to the control surface. A latch assembly (37) is provided which is mounted to the structure which releasably engages the actuator. Preferably, the latch assembly (37) comprises a grooved flange (38) mounted on the actuator (12) and a solenoid (47) mounted to the aircraft structure which is adapted to move a locking pin (44) from a first position in engagement with the grooved flange (38) to a second position out of engagement with the groove. In a second embodiment, a second rotary actuator (114) is mounted to the aircraft structure and is adapted to rotate the actuator (81) upon its failure and after the latch assembly is activated.

  • Patent number: 4546939
    Abstract: The invention is an ECS system designed to utilize an induction motor (12) and a cabin compressor (14) for providing pressurized air that serves as a source of energy for heating, cooling, pressurizing and other air needs of modern aircraft. An aircraft engine driven generator, preferably a permanent-magnet generator (of the samarium-cobalt, SmCo, type), furnishes variable-voltage/variable frequency, VV/VF, power to the motor (12). The electric motor itself in the preferred embodiment is a highly reliable squirrel-cage induction motor (12) powered directly from the VV/VF supply, with the result that its speed is proportional to the generator frequency, which in turn is dependent on the aircraft engine speed. The main cabin compressor (14) and a secondary (auxiliary) supercharging compressor (18) are both mounted on the motor shaft.
