Abstract:

The two legs of a headlamp filament are welded to a headlamp filament shield to form a subassembly intermediate in the manufacturing process. The rigid nature of the filament/shield subassembly thereupon allows handling during assembly without displacing the filament from its precise location with respect to the shield as required by modern automotive headlamps. The filament/shield subassembly is welded to support pins in its final location in the lamp. A portion of the filament shield, orginally providing an electrical short circuit across the filament is trimmed away after welding to the support pins to make the lamp operational.

Abstract:

A fishing device for locating the depth of a body of water and for adjusting a hook on a fishing line to be set at any desired height relative to the bed of the body of water. The device comprises a float containing a tubular assembly. The assembly contains two frictional means: one permits the line to move only towards the bed of the body of water and the second restricts movement of the line in both directions. A disengagement means, when actuated, permits free movement of the line in both directions.
