Abstract: The presently disclosed subject matter relates to methods for quantifying the amount of N-methyl-2-pyrrolidone (NMP) in a sample. In one exemplary embodiment, a method for the quantification of N-methyl-2-pyrrolidone (NMP) in a sample includes introducing a sample that includes 1,3-butadiene and NMP, if any, into a gas chromatography system coupled to a nitrogen phosphorous detector to produce a first signal; and comparing the first signal to a second signal produced from a standard of a known NMP concentration, to quantify the amount of NMP in the sample, where the sample is not concentrated for NMP prior to the introduction of the sample into the gas chromatography system.

Abstract: The dental flossing device has an elongate handle with a removable and disposable floss holder at its distal end. A slide is installed along the handle, with the slide reciprocating axially along the handle when manipulated by a user of the device. The slide operates a flexible cable that in turn reciprocates the floss holder orthogonally relative to the elongate axis of the handle. Upper and lower bite pads are installed upon the distal end of the handle, with the user of the device gripping the pads, and thus the distal end of the device, between the teeth. The floss extending across the floss holder is then reciprocated between adjacent teeth by operating the slide on the handle. The device can also include a timer and alarm to notify the user of the appropriate time to be spent flossing, and to remind the user to floss daily.

Abstract: A hydraulic system is disclosed for use with a machine. The hydraulic system may have a tank, a motor with a fluid inlet and a fluid outlet, and a pump configured to draw fluid from the tank and discharge the fluid at elevated pressures to the motor. An output of the pump is adjustable to regulate a speed of the motor. The hydraulic system may also have a low-speed valve located between the fluid outlet of the motor and the tank. The low-speed valve may be configured to reduce a positive speed of the motor below a lowest positive speed attainable through control of pump output.

Abstract: A system, method, and computer program product for real-time content delivery in a communication system utilizing push-to-talk wireless capabilities for voice interaction with a wide range of data processing system applications. By utilizing a vocalizer voice-to-text translation system, various embodiments allow real-time, push-to-talk interaction with conventional voice-response systems, conventional data processing system applications, and other text-based applications such as instant-messaging applications.
