Abstract: A catalytic converter for transforming polluting gases into non-polluting gases. The converter comprises an open-ended elongated shell of rust-resistant alloy; a transverse partition member comprising a metallic grill coated with silver, palladium or mixtures thereof, within said elongated shell, proximate to and spaced from the open inlet end of the elongated shell; and a metallic mesh, coated with silver, palladium or mixtures thereof in a first open-ended container having its inlet end affixed to the downstream transverse surface of the partition member, and forming a first gas passageway between the elongated shell and the outer surface of the container. A metallic mesh coated with chromium in a second container removably attached to the outlet end of the first container, forms a second gas passageway contiguous with said first gas passageway. The open outlet end of the second container is spaced from the open outlet end of the elongated shell.

Abstract: This invention relates to a new rust-resistant alloy for use at high temperatures, especially in mufflers in automotive vehicles.

Abstract: Disclosed is a collapsible shipping container comprising an upper storage section and a lower pallet section secured to said upper section by a plurality of pins. The upper storage section includes a pair of U-shaped panels which, when fastened to the pallet section, form four sides of the shipping container. A detachable lid is thereafter secured to the top of said container by straps and said lid, said panels, and said pallet form the interior surfaces of said shipping container. The pallet includes upper and lower sections which are connected together through raised portions thereby forming a plurality of foot pedestals. The resulting pallet is accessible by fork lift truck from any direction and can be swung by any crane. A unique resilient snap-lock fastener comprising a pair of resilient arms extending from a base and adapted to pass through a recess in said pallet section and to engage a lip located internal to said pedestals secures said panel sections to said pallet section.

Abstract: A series of precast concrete links interconnect the upper ends of vertical wall panels and a precast roof. The links are formed with slots at their longitudinal ends for the reception of specially formed reinforcement members, as required by the design of the building under construction, and some of said links being formed with openings intermediate their ends.
