摘要： A quarter turn quick connect fitting assembly (10) for connecting miniature fluid conduits, such as tubing, includes a first fitting (12) having radially projecting pins (28) and a second fitting (14) located within a rotatable quarter turn nut (16) having spiral grooves (48) which receive the pins. The first fitting defines a central passage (26) and the second fitting defines a central passage (42) which may each be configured to slidably receive a hollow tube set (104), or to threadably receive an externally threaded mating fitting. The quarter turn quick connect fitting can be configured to attach to the end of a column, and can include an adapter (158), which houses a guard column (160), or a frit (188) for filtering the fluid passing through the quarter turn quick connect fitting assembly. The quarter turn quick connect fitting is assembled by sliding the pins of the first fitting into the grooves of the quarter turn nut and rotating the quarter turn nut through approximately 90° with respect to the first fitting, thereby securely seating the pins within angled areas defined at the ends of the grooves.

摘要： An integral fitting and filter assembly includes a tubular body (119) having a integral proximal fitting piece (121) and an integral distal fitting piece (122). A central passage (125) extends through the proximal fitting piece and the distal fitting piece of the body. A tubular filter assembly sleeve including a filter sub-assembly (142) and tubular extension sleeve (140) is slidably received within the central passage of the body. The filter sub-assembly includes two end caps (144, 145) and a center piece (146). The center piece is packed with a selective chemical-absorbent packing material (26), that is retained within the center piece by first and second porous plugs (148) secured within opposite ends of the center piece of the end caps. The filter assembly is slidably inserted into the body, and is automatically adjustably positioned longitudinally to provide a pre-column filter that may be used to mate with differently configured mating fittings, such as high-performance liquid chromatography instrument inlet fittings.

摘要： The present invention constitutes a system for generating an elevator command signal for directing a pilot in guiding his aircraft along a path effective for recovering from hazardous windshear conditions. The system includes a descending mode guidance subsystem (10), an ascending mode guidance subsystem (12) and a switching mechanism (14) for shifting between the two subsystems. The descending mode subsystem includes an acceleration generator (20), a flight path command generator (22), a flight path error generator (24), a descending mode pitch error generator (26), an airspeed control device (28) and a descending mode signal controller (30). These components are connected serially together and operate to form an elevator command signal corresponding to the acceleration required to halt the descent of the aircraft by a fixed altitude level. They also function to control and condition this signal with respect to important flight parameters such as the aircraft's maximum safe angle of attack and the response capabilities of the pilot and aircraft.

摘要： A digital-based control data processing system detects during system operation the occurrence of data processing errors. Data processing accuracy is verified by receiving output information developed from system input information in accordance with a first operational function, computing a derived version of the system input information in accordance with a second operational function, and comparing the derived version of the system input information to the actual system input information to determine whether they differ by a predetermined operational tolerance. This method for verifying processing accuracy is especially advantageous for detecting latent software errors which are unique to a particular computer program. The processing system includes display apparatus which develops from the output information a set of display symbols that convey the information on a monitor screen to the pilot. Assigned to each display symbol is an identifying tag which identifies in real time a display symbol that conveys erroneous information.

摘要： A valve (10) is used to introduce fluid from a syringe (22) into the inlet (88) of the pump of an HPLC instrument (12). The valve includes a valve body (14) that is connected to the HPLC instrument for fluid flow communication with the instrument inlet. A valve rotor (16) is rotatably engaged with the valve body. A collar fitting (18) included on the valve rotor is connectable to the syringe. The syringe acts as a valve lever, and is displaceable to rotate the valve rotor about an axis of rotation (32) between an "off" position, in which fluid flow between the syringe and the HPLC instrument inlet is prevented, and an "on" position, in which fluid flow between the syringe and the HPLC instrument inlet is permitted. The valve enables one-handed priming operation.
