摘要： Process for loading of test pins into printed circuit board test fixtures. Test pins are loaded into a loader body, and locked thereto by a sliding locking plate through frictional engagement at an interface where in test pin hole is of a reduced surface area. Upon alignment of the loading body to the sliding lock plate, increasing surface area of each test pin hole, the test pins drop through the loading body into the test fixture. The lower surface area of the head of the test pin controls movement of the test pin between the loading body and the test fixture through gravity free fall. After circuit board testings, the test pins are reloaded back to the original location within the loader body for subsequent new circuit loading and testing.

摘要： A filtration system that rotates in conjunction with a blower wheel, and a method of attaching the same. The blower wheel typically has a plurality of fan blades arranged in a spaced relationship radially around a blower cavity to define a flow path extending radially outward from the blower cavity through the fan blades when the blower wheel is rotating. The filtration system includes a filter cartridge releasably attachable to the blower wheel in an engaged configuration. The filter cartridge includes a filter medium defining a generally center opening and a filter surface configured to be positioned generally adjacent to the fan blades and to extend across at least a portion of the flow path. In one embodiment, a plurality of flow passages extending through the filter medium.
