Abstract: Disclosed is a process for neutralizing an inorganic acid in the presence of a halogenated aliphatic polybasic acid or anhydride. The neutralization is carried out by adding to said acid or anhydride a primary or secondary amine containing at least two active hydrogen atoms per molecule as determined by the Zerewittenoff Method, and neutralizing the inorganic acid in the presence of the polybasic acid or anhydride. In one embodiment, the halogenated aliphatic or alicyclic polybasic acid or anhydride is present in a mixture wth a halogenated aromatic polybasic acid or anhydride and with a polyol and the neutralization is carried out before substantial polymerization occurs between the acids and polyol.

Abstract: Disclosed are haloaryl halobenzene sulfonates of the formula ##STR1## wherein X and X' are each independently selected halogen, preferably chlorine or bromine; n is a integer of from 1 to 5 and m is an integer from 1 to 4, provided that the sum of n plus m is an integer of from 4 to 9; and R is selected from hydrogen, halogen (preferably chlorine and bromine), and ##STR2## wherein Y and Y' are each independently selected halogen, preferably chlorine and bromine, m' is an integer from 1 to 4 and n' is an integer of from 1 to 5, provided that m'+n' is from 4 to 9 and Z is an alkylene or alkylidene containing from 1 to 6 carbon atoms. Also disclosed are polymeric compositions containing these compounds as flame retardants.

Abstract: There is provided a flame-retarded non-woven material which contains a mixture of flame retardant and vinyl chloride latex, wherein said flame retardant is selected from the group consisting of ##STR1## wherein a and b are integers independently selected from the group consisting of 1, 2, 3, 4 and 5, a plus b is from about 6 to about 10, c is an integer of from 1 to 4, and alkylene is a straight chain carbon group having from one to six carbon atoms; and wherein more than 50 percent (by weight) of said flame retardant consists of particles with a diameter of from about 2 to about 25 microns.

Abstract: A pile fabric knitting apparatus has controllable means, several representative embodiments of which are disclosed, separate from fiber supply means and responsive to dynamic control means, i.e., transducer, control tape, etc., functioning during operation of the apparatus, for regulating the quantity of pile fibers transferred or retained by the reciprocating knitting needles from respective fiber zones provided by pile fiber feeding means to which the fibers are delivered by the supply means. Such controllable means may operate in addition to or alternatively to fiber supply control at the supply means.

Abstract: Sinker cam segment having its ends beveled at a compound angle, so that the end surfaces are in a plane having no elements which are either radial or axial with reference to the center line of the cam ring on which the segment is used.
