Abstract: A trolling weight body of heavy metal has two angled front faces and a flat bottom and flat top with a full length vertical top fin and extending vertical tail fin. Attaching the downrigger line to a hole in the top edge of the top fin noses the front down slightly to cause the top flat surface to act as a diving/planning force to maintain the trolling weight directly below the downrigger rod for a true depth reading on the downrigger line. Visual, auditory, and sensory stimulations to attract fish are provided by intersecting cross holes through the trolling weight body and a series of loose rings with colored beads dangling from a series of vertical holes along the back edge of the tail fin.

Abstract: A bi-level test fixture for testing printed circuit boards is provided. A series of guide pins emanate downwardly from the diaphragm board through corresponding guide pin apertures present through the probe plate. Upon application of a full vacuum to the test fixture, the diaphragm board is drawn completely toward the probe plate thus extending the guide pins through their corresponding guide pin apertures. The portion of the guide pins below the probe plate engage with a pneumatically actuated fork member. Upon release of the vacuum to the test fixture, the upward travel of the diaphragm board is limited and at a distance so that only functional test probes are in contact with the unit under test. Application of a full vacuum again enables disengagement of the fork member with the guide pin to allow the diaphragm board to travel fully upward to its resting position for removal of the unit under test.
