  • Vulcanizable compositions of halogen and carboxyl containing acrylate elastomers, 2,5-dimercapto-1,3,4-thiadiazole, a Group IVA metal oxide or salt and a tetraalkyl thiuram sulfide
    Patent number: 4434274
    Abstract: Dual cure site acrylate elastomers containing both active halogen and carboxyl groups are compounded with a combination of 2,5-dimercapto-1,3,4-thiadiazole, a Group IVA metal oxide or salt thereof and a tetraalkyl thiuram sulfide to provide compounds having an excellent scorch/cure rate balance and balance of desirable physical properties in the vulcanizates thereof.

  • Method of selecting operation of a fluid-bed reactor and apparatus for doing so
    Patent number: 4226798
    Abstract: A method is disclosed for using a pendulum viscometer having damped torsional oscillations, in a laboratory catalytic fluid-bed reactor, to monitor a propensity to stick which is exhibited by certain supported catalysts. A fluid-bed of such catalysts has been found to become suddenly more sticky just before a point at which a change in pressure drop across the fluid-bed can be measured due to a process "upset". At this point ("the inversion point"), the upset is usually irremediable. The method includes correlating data on catalyst stickiness from a laboratory reactor operating at atmospheric pressure, with an expected level of catalyst stickiness in a commercial reactor operating at elevated pressure.A pendulum viscometer and related auxiliary apparatus is disclosed for magnetically and electrically measuring and recording the rate at which the pendulum's torsional oscillations are damped.
