A device for removing undesirable aquatic vegetation from lake bottoms. The device includes a weed trap and an elongated handle pivotally mounted thereto. The trap is formed of mesh, screen, etc. and includes at least one flat side and an open top. A cutting bar is disposed along a top edge of the flat side. A releasable latch is provided to selectively latch the handle to the trap.

Aquatic weed trap

The novel tester comprises jaws for orienting the component about a longitudinal axis of the tester in order to ensure proper positioning of the electrical connectors for engagement by test contacts of the tester. Each component usually has a mounting surface for engaging a dot of glue by which the component is held to the circuit board, and the novel tester provides means for generally preventing tilting of this mounting surface relative to longitudinal axis of the tester during testing.

Apparatus for automated testing of surface mounted components

A dispensing nozzle tip is advanced into engagement with the particular position of the circuit board to which material is to be applied, and a reactive force on the nozzle tip from the circuit board is sensed by variation in the output from a load cell such that an exact spacing may be provided between the nozzle tip and that portion of the surface to which material is to be dispensed. Having provided such spacing between the tip and surface, the flowable material is dispensed and a reactive force from the surface, via the flowable material, is sensed by the load cell arrangement to provide for metering of a dose of the flowable material. Such surface location and dispensed dosage sensing is performed for every dose of material to be applied.
