  • Corrosion and alkali-resistant compositions and methods for using the same
    Publication number: 20070009742
    Abstract: A corrosion resistant, alkali resistant coating composition is disclosed. The composition comprises a binder comprising a reaction product of an epoxy-containing material and a phosphorus-containing material together with a curing agent. Aminoplasts, especially melamine-based aminoplasts, are particularly suitable curing agents. A source of silicon can optionally be included. The compositions also provide excellent adhesion and can be used with or without a weldable primer. The compositions are applied to and cured on a metal substrate.

  • Flight for use on a conveyor belt
    Patent number: 4712668
    Abstract: A flight has a wing with an elongated support rod embedded in said wing along a fixed edge thereof. To flight or wing has two free ends that are not affixed to said support rod. A metal cable is embedded in each of the free ends and extends from the free ends to the support rod. The metal cable in affixed to the support rod to reduce the possibility of the free ends breaking off from the remainder of the wing.
