    摘要： The disclosure relates to process for making derivatives of vinylphosphonic acid or vinylpyrophosphonic acid. To this end, a ketone is reacted with tetraphosphorus hexoxide in the presence of catalytic proportions of a proton-yielding substance. In the event of the products desired to be produced being vinylphosphonic acid derivatives, the vinylpyrophosphonic acid derivatives first obtained are hydrolyzed with an equivalent quantity of water.

    摘要： The disclosure relates to a process for making derivatives of vinylpyrophosphonic acid, wherein a ketone is reacted with tetraphosphorus hexoxide (P.sub.4 O.sub.6) in the presence of a catalytically active proportion of a proton-yielding substance at elevated temperature. Vinylphosphonic acid derivatives are obtained by hydrolyzing the vinylpyrophosphonic acid derivatives with an equivalent proportion of water. More particularly, the ketone used is a compound of the following general formula ##STR1## in which either R stands exclusively for a halogen and R' either stands for a halogen or hydrogen, a halogen-substituted or unsubstituted alkyl, aryl, alkaryl or aralkyl group having from 1 to 18 carbon atoms, and R" stands for an alkyl, aryl, alkaryl, aralkyl or alkenyl group having from 1 to 18 carbon atoms, or R" stands exclusively for an alkenyl group having from 2 to 18 carbon atoms and R and R' being identical or different each stand for hydrogen or a halogen or a halogen-substituted or unsubstituted alkyl, aryl, alkaryl or aralkyl group having from 1 to 18 carbon atoms.

    摘要： A method and apparatus for producing a ribbon free randomly wound yarn package is disclosed, and wherein a plurality of critical winding ratios at which undesirable pattern formations or ribbons would normally occur are determined and stored in a microprocessor control unit. During the winding operation, the spindle speed and traversing frequency are monitored by sensors and are transmitted to the control unit, and the control unit computes the optimum time for rapidly changing the traversing frequency so that the actual winding ratio moves rapidly through each of the approaching critical winding ratios. The original traversing frequency is re-established after having passed beyond each of the critical winding ratios.
