  • Water soluble ammonium siloxane compositions and their use as fiber treatment agents
    Patent number: 5707434
    Abstract: The present invention relates to a water soluble ammonium siloxane composition comprising (A) an aminosiloxane solution comprising a mixture of (i) a triorganosilyl-endblocked aminofunctional siloxane, (ii) an aminofunctional siloxane which it triorganosiloxy-endblocked at one end and hydroxy-endblocked at the other end, and (iii) a hydroxy-endblocked aminofunctional siloxane, (B) a cyclic aminofunctional siloxane, and (C) a polydimethylcyclosiloxane where the aminofunctional group is selected from --R.sup.3 --.sup.+ NHR.sup.5 --R.sup.4 --.sup.+ NH.sub.2 R.sup.5.2A.sup.-, --R.sup.3 --.sup.+ NH.sub.2 --R.sup.4 --.sup.+ NHR.sup.6.A.sup.-, --R.sup.3 --NR.sup.6 --R.sup.4 --.sup.+ NH.sub.3.A.sup.-, --R.sup.3 --.sup.+ NH.sub.2 R.sup.5.A.sup.-, where R.sup.3 is a divalent hydrocarbon radical, R.sup.4 is a divalent hydrocarbon radical, R.sup.5 is hydrogen, alkyl, aryl, or arylalkyl, R.sup.6 is a --C(O)R.sup.7 group where R.sup.7 is a monovalent hydrocarbon group or aryl, and A.sup.

  • Pulverizer hydraulic drive
    Patent number: 4013235
    Abstract: A pulverizer having four hydraulic drive motors for rotating the grinding ring or bowl. The motors are mounted so as to be easily accessible, so that one or more can readily be removed for repair during which time the pulverizer can remain in operation. The speed of rotation of the grinding bowl can be varied by either changing the pressure of the driving hydraulic fluid, or by stopping the supply of fluid to one or more of the motors.
