Abstract: In a first stage of this process an elastomer latex is prepared in aqueous emulsion in the presence of an ionic surface-active agent, from at least one ethylenically unsaturated monomer; then, in a second stage, at least one vinyl monomer which is insoluble in water or poorly soluble in water is added to the latex thus obtained. According to the invention, the ionic charges carried by the said latex are quantitatively neutralised by adding to the latex + monomer(s) system a transfer agent carrying ionic charges of opposite sign to those of the surfactant employed in the first stage, in order to produce the transfer of the particles of the said latex into the said vinyl monomer(s); and, in a third stage, a suspension or bulk polymerisation is performed on the phase consisting of the said monomer(s) from the second stage and containing the transferred latex particles.

Title: A method and an arrangement for accurate digital determination of the time or phase position of a signal pulse train
Inventor: DENT PAUL WILKINSON
IPC: G01R25/00
Filed: 1990-03-28
Granted: 1996-08-23
Abstract: The invention relates to a method and an apparatus for accurate digital determination of the time or phase position of a signal pulse train in relation to a fixed time or frequency reference. The arrangement generates and produces directly on the output a digital word corresponding to the measuring value current at that time. The pulse train is compared in a plurality of EXCLUSIVE-OR gates (OR0-OR3) with a number of reference clock signals (RCL0-RCL3) which are mutually displaced in time. There is produced on the output of each gate a signal (MS0-MS3) which is dependent on the input signals of the gates with respect to frequency and pulse ratio. The output signals from the gates are sent to a comparison circuit (CO) in which a MIN of MAX operation is carried out, the pulse ratio of the output signals (MS0-MS3) being compared and the output signal which lies nearest to a predetermined pulse-ratio value being subjected to analogue/digital conversion in a converter (AD). The pulse train, in digital form, is thereafter code-converted in a code converter (CC) together with the three most significant bits taken from the pulse train prior to the AD-conversion process. The thus produced binary code can be corrected for systematic deviations resulting from frequency differences between the frequency, reference frequency and/or sampling frequency of the pulse train, by the addition/subtraction of a predetermined numeric sequence.

Title: A circuit for eliminating noise of video signal
Inventor: KIM JUNG-HOON
IPC: H04N5/213
Filed: 1991-10-17
Granted: 1997-12-19
Abstract: A noise removing circuit of video signals is provided to entirely remove a pulse-type noise. The circuit comprises: a subtraction means for calculating the differences of a first to fourth pixels; an absolute value counter for counting an absolute value of the output signal; a noise central judgement means for searching a central of noise; a horizontal extension means of noise width for expanding the noise to the horizontal direction; and a noise removing means for removing the noise by selecting an average value of the first pixel and the second pixel.
