A moveable undercarriage for supporting and moving a welder over a ground surface having a base to support the welder, a front and rear axle secured to the base each having two wheels rotatably secured to the axles, and a push bar secured to said base to move the base over a ground surface. The front and rear axles are positioned on the base such that the center of gravity of the welder lies between the axles. The front and rear axles are spaced apart a distance that is less than three times the sum of the radii of the front and rear wheels. The undercarriage includes a brake to engage at least one wheel in a locked position. The push bar has a lift bar to facilitate in the moving of the base.

All-terrain undercarriage

Handheld input device for computers

An improved container for the storage, display and protection of collectable items such as graded coins, stamps, jewels and other valuables is disclosed. Display of the collectable items is enhanced by an optical element which provides reflective means for viewing the item indirectly. A reflecting prismatic ring is preferred to provide viewing of the periphery of a cavity or the collectable item enclosed therein. In a second embodiment where two or more components may completely enclose the cavity, various tamper-resistant and tamper-evidencing features are further incorporated in the container design to discourage and prevent fraudulent substitutions of collectable items, modification of grade and value certificates enclosed therewith, or counterfeiting of container components.

Protective coin holder

An improved coin holder for the storage, display and protection of graded coins and other valuables is disclosed. Various tamper-resistant and tamper-evidencing features of the coin holder discourage and prevent fraudulent attempts to obtain access to replace graded coins with those of lesser quality, or tamper with coin grading certificates sealed with the coin in an inner element. Additional features discourage and make difficult the wholesale counterfeiting of the coin holder itself. The coin holder may be partially disassembled to obtain direct, unobstructed access to the coin contained therein, while maintaining the integrity of the grading certificate retained in the inner element along with the coin. The device introduces greater security and certainty into the process of marketing graded and increasingly valuable numismatic items. With minor modifications, the present invention may be used to secure grading small and medium-sized valuables for transport, grading and sale, such as diamonds, jewels, jewelry, stamps, and the like.
