摘要:
A method for producing an oxidized wax comprising (a) providing a uniform high molecular weight polyolefin resin feedstock having an average particle size smaller than about 30 mesh and a standard deviation in particle size of not greater than about 125 μm; and (b) oxidizing the resin particles in their solid state to produce a wax having a predetermined acid number.
摘要:
A data acquisition system and method are described that may be used with various spectrometers. The data acquisition system may include an ion detector, an initial processing module, and a spectra processing module. The initial processing module is provided for processing the ion detection signals and for supplying processed signals to the spectra processing module. The spectra processing module generates spectra from the processed signals and supplies the generated spectra to an external processor for post-processing. The spectra processing module may include an ion statistics filter and/or a peak histogram filtering circuit.

A data acquisition system and method are described that may be used with various spectrometers. The data acquisition system may include an ion detector, an initial/transient processing module, and a spectra processing module. The initial/transient processing module is provided for processing the ion detection signals and for supplying processed signals to the spectra processing module. The transient processing module may contiguously sample the ion detection signals at a rate of at least 1.5 GHz. The spectra processing module may generate spectra from the transients at a rate of at least 50 spectra per second. The initial processing module may be configured to have a sensitivity that is sufficient to detect a single ion received within one of over at least 100 transients and to detect and quantify a number of ions simultaneously striking said ion detector up to at least 10 simultaneously striking ions.

A data acquisition system and method are described that may be used with various spectrometers. The data acquisition system may include an ion detector and a processing circuit. The processing circuit may include an initial processing module and a spectra processing module. According to one embodiment, the spectra processing module generates stick spectra and supplies the stick spectra to an external processor. The stick spectra comprise a peak intensity, resolution, and a location in the spectra for each detected peak. The initial processing module may contiguously sample the ion detection signals at a rate matched to the capabilities of the ion detector (up to at least 1.5 GHz) over a full spectral range. The spectra processing module may receive the processed signals and generate spectra from the processed signals at a rate matched to the time response of the separation techniques (up to 200 spectra/second).

A controller for energizing a power window or panel such as a power sunroof. The disclosed controller senses both hard and soft obstructions and deactivates a motor that moves the sunroof when an obstruction is detected. The controller also senses obstructions during start-up of the motor and regulates the speed of the window or panel by pulse width modulating motor energization signals.

A data acquisition system and method are described that may be used with various spectrometers. The data acquisition system may include an ion detector, an initial processing module, and a spectra processing module. The initial processing module is provided for processing the ion detection signals and for supplying processed signals to the spectra processing module. The spectra processing module generates spectra from the processed signals and supplies the generated spectra to an external processor for post-processing. The spectra processing module may include one or more of: a cross-spectra filter for filtering data in each spectra as a function of data in at least one prior spectra; a shaping filter for removing skew and shoulders from the processed signals; a sharpening filter for sharpening the peaks of the processed signals to effectively deconvolve and separate overlapping peaks; an ion statistics filter; and a peak histogram filtering circuit.

The invention relates to zeolite particles which are at least partially coated with a coating that is capable of delaying the release of heat from the zeolite particles upon contact with water over time. The coating effectively at least partially blocks the pore structure of the zeolite particle from contact with water, thereby delaying contact between water and the zeolite, and prolonging the warming effect caused by such contact.
