Abstract: A method of determining whether one or more forms of a nucleic acid analyte are present in a sample. The method includes dissolving an amplification reagent with a first solvent, where the amplification reagent contains oligonucleotides sufficient to amplify and detect a first region of a first form of the analyte, where the first solvent contains one or more oligonucleotides which, in combination with the oligonucleotides of the amplification reagent, are sufficient to amplify and detect a second region of a second form of the analyte, where the one or more oligonucleotides of the first solvent are insufficient to amplify and detect the first or second form of the analyte, and where the first and second regions each comprise a different nucleotide base sequence.

Abstract: A method and apparatus for applying a foamed mixture of paints on a structural surface. A continuous stream of high velocity gas moves through a nozzle and is directed toward the structural surface, and two or more paints may be intermittently moved into the gas stream of the nozzle and aerated and mixed with each other and moved with the gas stream to form a foam that is applied to the structural surface. The components of the foamed mixture may include single component or plural component materials such as polyurethane foam, adhesive, and polyurea formulations, and may be moved through a volumetric metering device consisting of material heaters, a heated hose, and an applicator gun. The nitrogen gas stream fluidizes the mixture as it passes through and out of the nozzle and forms the mixture into a foam that is applied to the structural surface.

Abstract: Various examples are provided related to low pressure delivery, e.g., less than 250 psi at the point of application, of plural component system from unpressurized parts A and B material supplies. In one example, a system includes a polyurethane spray foam (“SPF”) raw material supply including parts A and B and a fluid handling system that can deliver the SPF raw material at low pressure to a metal spray gun in metered amounts through separate material fluid paths/conduits via a heated hose length and a whip hose. The fluid handling system can also deliver air at low pressure to the spray gun through separate air stream paths so that the air is communicated to the part A and B material conduits forward of the part A and B material input locations, where they are supplied separately to a mixing nozzle that is engaged at an end of the spray gun.

Abstract: A reset detector is disclosed, which monitors the hardware reset of the subsystem(s) involved, in order to verify that the hardware reset has placed the subsystem in a correct reset state. Thus, in order to verify that an initial hardware reset has occurred, the subsystem software (e.g., during boot-up) detects the initial reset status of the reset detector, and blocks any additional reset attempts that may occur. In other words, the reset detector verifies that the subsystem hardware has been reset correctly, before the application software can proceed into an operational mode. An example reset detector circuit is disclosed, which includes a local reset signal generated by an RC delay circuit. The local reset signal is isolated from the system reset function, which allows the reset detector circuit to be initialized and reset separately from the system reset. Once the reset detector circuit is initialized, it monitors the system reset request line.

Abstract: An automatic termination circuit is disclosed. The automatic termination circuit includes an adjustable termination resistance device having an output terminal for connecting the adjustable termination resistance device to a transmission line, wherein the adjustable termination resistance device has an associated termination resistance. The automatic termination circuit is operable to automatically adjust the termination resistance associated with the adjustable termination resistance device using feedback, wherein the feedback is based on at least an output voltage at the output terminal.

Abstract: A method and system are described for continuously producing plastic optical fiber. The method involves melting a polymeric starting material in a continuous screw extruder and then extruding the melted polymer vertically upward (i.e., against the force of gravity) to form a plastic optical fiber with a uniform core cross section.

Abstract: A drive shaft rotated by a drive gear is coupled to an epicyclic gear arrangement which is rotatable as a unit about the drive shaft's longitudinal axis, as well as about its own axis. A driven gear is rotatably mounted on the on the drive shaft between the drive gear and the gear arrangement. Facing surfaces of the drive and driven gears are provided with annular concavities. A pivotally adjustable friction disk extends between, and in contact with, the concave surfaces. The opposite side of the driven gear is operatively connected to the gear arrangement. When the drive shaft is rotated, the gear arrangement is rotated about its own axis in response to drive shaft rotation and is rotated about the drive shaft's axis in accordance with the position of the friction disk. The speed and direction of the wheel-driving output are thus controlled.

Abstract: A cantilevered spring is supported proximate the transaxle of a piece of power equipment so as to be operatively related to the shift lever used to actuate the transaxle. The cantilevered portion of the spring comprises a main resilient section and an extension at its outer end which lies in a plane angularly related to that of the main section of the spring. The extension is provided with an elongated slot having a major axis which extends parallel to the plane of the spring's main section. The shift lever is received in the slot whereby actuation of the lever in a direction normal to the slot's major axis is resisted by the spring.

Abstract: A grass catcher is mounted on the rear of the riding type mower to receive grass clippings from the mower unit. The grass catcher includes a bag suspended from a rectangular frame and a cover to keep the grass clippings within the bag. The cover is of a novel construction and includes a rearwardly disposed vent or louver extending rearwardly beyond the frame to which the grass-catcher bag is connected. The overhanging vent portion extends substantially the full transverse width of the grass-catcher bag and its supporting frame, and includes a downwardly facing discharge opening. A vertically disposed screen is mounted within the grass-catcher cover immediately forward of the downwardly facing discharge opening. The screen also extends substantially the full transverse width of the grass catcher and its supporting frame so that the grass clippings blown into the grass catcher will not escape with the air passing through the downwardly facing opening.

Abstract: The four-wheel lawn and garden tractor has an underslung two blade mower unit and a rear mounted grass catcher. The multiple spindle mower unit incorporates special baffling to improve lateral movement of cut grass from the mower housing. The conduit between the mower housing discharge opening and the rear mounted grass catcher includes a unique elbow part having a configuration which facilitates efficient movement of the grass from the mower to the catcher. The grass catcher is vented so that there is very little back pressure in the interior of the grass catcher. Venting is accomplished by provision of a downwardly facing opening along the rear of the grass catcher cover, the latter being molded of an impervious plastic material. The grass catcher cover has a downwardly extending skirt at the front thereof with a pair of laterally spaced semicircular notches adapted to receive a discharge conduit. Thus the cover may be used on tractor mowers discharging to either their left or right side.

Abstract: A riding type mower is provided with a grass catcher attachment having removable container and cover structures. The container structure includes a horizontally disposed quadrilateral frame carrying a large container. The cover structure includes a molded cover and a screen extending downwardly from the cover with resilient clips or latches at the lower edge adapted to snap onto the container frame. A discharge chute from the mower directs the cut material rearwardly to a blower mounted on the rear of the mower. The blower discharge directs the cut grass upwardly toward a deflector formed by the shape of the top of the cover. The user may use the container to catch cut grass or may at his option place three plastic bags, such as garbage can liner bags, in lateral side-by-side relationship inside the container. The plastic bags are held in place by four spring loaded retainers and by the clips which hold the cover structure onto the container frame.

Abstract: The carriage for the friction driving disc of a friction disc planetary transmission is shiftable axially on a pivot shaft by a manually operated cam to change the contact path of a pair of driven friction wheels connected to input gears of a planetary unit to effect infinitely variable forward and reverse speeds and neutral. The pivot shaft is transverse to and spaced from the axis of the driving disc. The driving disc is driven by a belt which, when placed under driving tension urges the carriage to pivot about its pivot shaft in a direction urging the friction driving disc against the driven friction wheels. Additionally, the carriage is urged by a pair of springs in the same direction to insure proper frictional engagement of the driving disc with the driven wheels.
