Abstract: A lamp unit is provided having polymer electrical conductors adhered to a non-conductive substrate in which adjacent conductors present a gap therebetween for securing a light radiating device within the gap the conductors of one embodiment having raised abutments formed in the conductors at the gap for capture of a light radiating device therebetween, such as an LED in said gap to hold the light device between the abutments to secure the light device in the lamp and power the light device.

Abstract: A hand tool or clamp, which is operable with one hand, includes a fixed jaw and a movable jaw. The movable jaw connects at one end to a movable slide bar. One way drive means, by operation of a trigger handle, releasably engages the slide bar with advances the movable jaw toward the fixed jaw or away from the fixed jaw. Disengagement of the one way drive means will allow for manual return movement of the movable jaw.

Abstract: A locking hole punch for punching holes in metal sheets, particularly metal sheets difficult of access such as metal C-studs, is disclosed. This hole punch comprises an arm member that has a head at the end of an outwardly curved portion and a first handle extending from that curved portion. A first lever member formed in a generally mating outwardly curved configuration is pivotably connected to the arm at the top of the arm handle at a first pivot. A generally straight second lever, which acts as a second handle spaced from the arm handle, is pivotably connected to the first lever member at a second pivot near the first pivot. A toggle member is connected to the second lever at a third pivot and to the arm handle at a fourth pivot. When the arm and second handles are pressed together, the toggle member is driven so that the second, third, and fourth pivots are moved into a straightline alignment so that the punch, which includes a punching pin, is driven into a working position with the head.
