Abstract: A small-scale dynamic simulator for crude oil refinery desalters has a pressurized oil deviblis configured to hold a supply of crude oil and a water deviblis configured to hold a supply of wash water. At least one chemical feed pump selectively adds emulsion breaker chemicals to the desalter simulator and a low shear metering pump is configured to pump crude oil and wash water through the desalter simulator. An emulsion forming device forms a crude oil-wash water emulsion that is then received in a desalter vessel. The desalting vessel is fitted with electric grids which simulate those found in electric desalters. The emulsion is resolved within the desalter vessel with the assistance of the emulsion breaker chemicals so the wash water and crude oil form distinct phases, with substantially desalted crude oil removed from an upper portion of the desalter vessel and substantially oil-free wash water removed from a bottom portion of the desalter vessel.

Abstract: A gas turbine engine cowl has a portion which translates axially of the remainder, to open or close a reverser gas flow gap. A yoke is attached to the fixed cowl upstream of the gap which yoke is engageable with a member on the translating cowl portion, by dropping thereover as the cowl portion closes the gap. Translation of the cowl portion actuates an abutment via a cam mechanism to release the yoke at such a time as to prevent the yoke dropping too soon, which would result in the cowl portion being unlocked.
