  • Process and apparatus for nucleation control adapted for reaction injection molding of cellular products
    Patent number: 4312820
    Abstract: A novel apparatus and method are provided for monitoring gas entrainment in liquid precursors for reaction injection molding (RIM). In accordance with the invention, a nucleated RIM precursor is sampled and the sample subjected to a controlled volumetric change. The measured pressure of the expanded or compressed sample is compared to that corresponding to the ideal degree of gas entrainment. The comparison is used to control the addition or withdrawal of entrained gas.

  • Coalescer filter unit drain device
    Patent number: H773
    Abstract: A spin-on type coalescer filter unit comprises a siphon tube which extends from inside the bottom of the filter element canister along the center line of the element, through the attachment nipple of the filter unit head, and into a fitting designed to receive the tube end. The fitting connects the tube to an oil drain passage so that coalesced oil may be driven through the siphon tube and to a drain line by high pressure in the filter canister.
