Abstract
The invention pertains to control means for apparatus for pneumatic transfer of a particulate material of the type having an air flow-way intersected by a particulate flow-way. The control means includes respective closure means for the air flow-way and particulate flow-way and a fluid-actuated sequencing mechanism for sequentially operating the closure means. When both closure means are open, the sequencing mechanism may be operated by a single control to cause closing of the particulate flow-way first, followed by closing of the air flow-way.
