Abstract: An earthquake and severe weather resistant, fail-safe building block and construction method for fabricating the blocks and structures therefrom. The blocks are hollow and include at least two subassemblies joined by interconnecting webs with provisions for single subassemblies to square off wall edges. Each subassembly includes upper and lower frames joined together by a plurality of structural columns perpendicular to the planes of the upper and lower frames. The upper and lower frames are dimensioned to form interfitting male and female receptacles that permit the blocks to be interconnected so that an assembly of blocks with structural integrity may be created by snapping together courses of blocks with each course staggered relative to the adjacent course.

Abstract: An oil recycling system and method which uses the same container to supply new oil and recycle old oil is accomplished through the use of a transfer tube designed for draining oil from the container into an engine and mutually exclusively oil from the engine oil sump into the container. The invention includes an oil collection bag which receives oil draining from an interface between the engine and an oil filter and transfers the oil via an oil collection bag tube into the container concurrently with oil draining from the engine via the transfer tube into the container.

Abstract: A plurality of walls are interconnected to form a hollow construction block including top and bottom contiguous block joining structure. The top contiguous block joining structure includes a first closed geometric shape adjacent to a second closed geometric shape. The first and second geometric shapes protrude above the side walls and have a width less than the width of the overall block and a combined length less than the length of the block. The bottom contiguous block joining structure includes a recess dimensioned to receive a joining structure dimensioned identically to the top contiguous block joining structure.

Abstract: A molded container block for fluidic material is fabricated with opposing sides comprised of a plurality of offset parallel planes interconnected to form interfitting geometric surfaces to allow interlocking and nesting of a plurality of container blocks by the geometric shapes of their exterior surfaces. A port allows filling and removal of materials from the container block. It is recessed into a corner of the container block so it will not interfere with the nesting function or detract from the container block structural strength. The shape of the container block is designed to provide nesting of any exterior surface of the container block with a mating exterior surface of a similar container block and to provide rigidity calculated to enable the container block to be used as a structural building unit.

Abstract: A construction method for fabricating structures and a system of building blocks utilized in the method is presented. The blocks are hollow and may be skeletal and formed from heavy gauge strips or molded. They include at least two sub-assemblies joined by interconnecting webs with provisions for single subassemblies to square off wall edges. Each skeletal subassembly includes upper and lower frames joined together by a plurality of structural columns perpendicular to the planes of the upper and lower frames. The upper and lower frames are dimensioned to form interfitting male and female receptacles that permit the blocks to be interconnected. D-lance snap fit structures are provided in the upper and lower frames so that an assembly of blocks with structural integrity may be created by snapping together courses of blocks with each course staggered relative to the adjacent course.
