Title: Ethylene recovery method
Inventor: COLLING PHILIP M
IPC: C07C67/055
Filed: 2000-06-27
Granted: 2006-11-11
Abstract: Ethylene is a commodity chemical used as a reactant in the production of vinyl acetate. Ethylene is relatively expensive thus making its recovery and re-use in the process encouraged. The present invention provides a method for the recovery of ethylene from the inert gas purge stream from the reactor loop in a vapor-phase process for making vinyl acetate. The method of the present invention includes the steps of contacting the inert gas purge stream containing ethylene with acetic acid in an absorption vessel; discharging a stream containing acetic acid and ethylene from one aspect of the absorption vessel; separating the ethylene from the acetic acid in the stream by contacting the stream with ethylene gas in a scrubber column; and recovering ethylene from a top portion of the scrubber column. The method may also include the step of recycling the recovered ethylene to the reactor loop for further use.

Title: Method and apparatus for high speed analog to digital conversion of video graphic signals using interleaving
Inventor: SMITH STERLING
IPC: H04N5/335
Filed: 2000-07-04
Granted: 2002-02-01
Abstract: A method for high-speed digitizing of an analog video signal using at least two parallel pipelined analog to digital converters. The analog video signal is a series of frames, each frame of the analog video signal being an alternating series of ""even"" horizontal lines and ""odd"" horizontal lines. All of the even lines are digitized in accordance with a first scheme and all of the odd lines are digitized in accordance with a second scheme. The relationship between the two schemes is that for any particular pixel in an even line, that pixel is digitized by one of the two ADCs; while for that same pixel in an odd line, that pixel is digitized by the other one of the ADCs. This ensures a checkerboard effect between the offsets in the two ADCs. Additionally, the frames of the analog video signal are viewed as an alternating series of ""even"" frames of video and ""odd"" frames of video. All of the even frames are digitized in accordance with a first scheme and all of the odd frames are digitized in accordance with a second scheme. The relationship between the two schemes is that for any particular pixel in an even frame, that pixel is digitized by one of the two ADCs; while for that same pixel in an odd frame, that pixel is digitized by the other one of the ADCs. This ensures the temporal smoothing between the offsets in the two ADCs.

Granted: 2003-09-01
Abstract: The present invention provides a structure of hydraulic pressure square wave generator, characterized in comprising several elements, wherein a three-port two-position high speed switch is the key technique for the design and manufacture of hydraulic pressure square wave generator. The principle is utilizing continuous mechanical rotation manner to achieve the three-port two-position switching function, serving as the generation principle of high speed hydraulic pressure square wave, which the switching function utilizes differential manner to achieve the generation of high frequency pressure square wave. The pressure balance of the high speed switch is an important factor that influences the performance of the hydraulic pressure square wave generator. In accordance with the present invention, the groove number defined in a rotating shaft and a fixed collar must be even to maintain the balance of radial pressure, otherwise bias of radial pressure will result in that smooth and stable rotation cannot be obtained. The groove number defined in the rotating shaft and the fixed collar also determines the number of switching action of the high speed switch generated by each turn of the rotating shaft, which is determined by the lowest common multiple of the groove numbers of the rotating shaft and the fixed collar. The achievement of present invention may reach the performance with high speed pressure square wave having a high frequency (2200 Hz). The pressure square wave is input to excite a hydraulic control system to be tested. Data corresponding to voltage signals output from a pressure sensor are taken as reference for evaluation, which is processed by techniques of spectrum analysis and system identification to obtain dynamic characteristics of the hydraulic pressure control system, such as various important parameters including response speed in time domain, band width, resonant frequency, and shifting function in frequency domain response. At the same time, the present invention provides the need of high frequency operation for hydraulic control system, and enhances quality and market competitiveness of hydraulic system.

Abstract: The present invention speeds up a bend alignment at an initial operation, such as right after power on, in the liquid crystal display with OCB mode. According to the present invention, when powered on, an LCD, which includes a LCD panel, a source driver that outputs image signals and a gate driver that sequentially outputs scanning signals, is controlled to output external bias voltage to common electrode lines and simultaneously stopping the driving of the gate drier and the source driver, according as a first time passes, is controlled to output specific common electrode voltage thereto instead of the external bias voltages and simultaneously to perform a driving of the source drivers and the gate drivers. As a result, at an initial operation, by applying high-level bias voltages instead of the common electrode voltage to the common electrode lines and simultaneously stopping the driving of the gate driver, the source driver and a back light, the speed of the initial bend alignment of a liquid crystal with OCB mode can be made high.
