redesigned for oil field use and was an outgrowth
of the Payne-Harris shaker. The rotary mud sepa-
rator was the first centrifuge introduced that was
different than those currently being used and was
originally developed by Mobil Oil Company.
1976-1977 The Brandt Company—This was the
first advertisment for Brandt, which began in
the early 1970s with tandem shakers that used
circular motion. These became the standard for
the industry for many years and were manufac-
tured in junior, singles, duals, triples, and quads.
Another unit advertised was the cascade-type
that used elliptical motion on the top deck to
remove coarse cuttings and gumbo and then
