Abstract: A circuit board processing system includes a wash tank configured to contain cleaning fluid, and a positioning subsystem configured to immerse a set of circuit boards into the wash tank. The system further includes a flow control subsystem having (i) a first set of nozzles disposed within the wash tank, (ii) a second set of nozzles disposed within the wash tank, and (iii) a controller. The controller is configured to direct the cleaning fluid through the first set of nozzles to provide a flow of the cleaning fluid in a first direction relative to the set of circuit boards. The controller is further configured to direct the cleaning fluid through a second set of nozzles to provide a flow of the cleaning fluid in a second direction relative to the set of circuit boards after providing the flow of the cleaning fluid in the first direction.

Abstract: A molded plastics taxidermy manikin receives an animal head skin stretched over and glued thereto with the aft open end of the head skin overlapping a peripheral extension of the manikin and being stapled to a wooden recessed insert provided therein. A center vertical groove is provided on the recessed insert and an elongated protuberance attached to the face of a mounting decorative wall plaque matingly engages the vertical groove. The protuberance-groove mating surfaces prevent relative horizontal and rotative movement between the plaque and the skin coated manikin while permitting relative vertical movement therebetween resulting in easy centering of the skin coated manikin on the plaque. A plurality of wood screws are positioned through predrilled holes in the plaque to engage the recessed wooden insert and attach the plaque to the skin coated manikin while the parts are maintained in relative centered position.
