Patent application number	Description	Published
20080302350	BLOCK SPLITTER ASSEMBLY AND METHOD OF PRODUCING WALL BLOCKS - The invention provides a block splitter assembly comprising first lower and second upper opposed splitter blade assemblies. The splitter blade assemblies have a splitting blade and two or more first forming blades. One forming blade is disposed to the right of and one forming blade is disposed to the left of the first splitting blade. The forming blades have forming edges. The splitting blade has a splitting edge that is straight, and the splitting blade has a greater maximum vertical dimension than the maximum vertical dimension of the forming blades. The splitting edge of the first splitting blade is opposed to the splitting edge of the second splitting blade.	12-11-2008
20090120029	WALL BLOCK WITH WEIGHT BEARING PADS AND METHOD OF PRODUCING WALL BLOCKS - A wall block having at least one weight bearing pad on an upper or lower surface of the block and a compression head and methods of making the block and making walls with the block.	05-14-2009
20090308015	RETAINING WALL BLOCK - A retaining wall block having a rear flange and a mold box and method of making the block. The mold box is configured with a mold cavity that includes a vertical flange forming cavity extending from the top of the mold box to the bottom of the mold box.	12-17-2009
20100308502	FLOATING CUT-OFF BAR FOR A MOLD BOX - A floating cut-off bar coupled to a feed drawer whereby a mechanism allows the floating cut-off bar to engage the specified contour of side rails and a division plate in a mold box assembly and aid in material distribution by screeding excess material and delivering additional material to areas of the mold box as necessary and method of making wall blocks therefrom. The specified contour of the side rails and optionally division plate is designed to optimally deliver material to achieve a specified uniform density of the block produced for greater structural integrity, strength and durability of the block.	12-09-2010
20100310695	FLOATING CUT-OFF BAR AND METHOD OF USE THEREOF - A floating cut-off bar that follows a preselected path of travel over a mold box during a block production cycle. The floating cut-off bar may be coupled to a feed drawer whereby a mechanism allows the floating cut-off bar to engage the specified contour of a division plate in a mold box assembly and aid in material distribution by screeding excess material and delivering additional material to areas of the mold box as necessary and method of making wall blocks therefrom. The specified contour of the division plate is designed to optimally deliver material to achieve a specified uniform density of the block produced for greater structural integrity, strength and durability of the block.	12-09-2010

20090277121	MASONRY BLOCK AND METHOD OF MAKING SAME - Molds and processes that permit high-speed, mass production of retaining wall blocks having patterned or other processed front faces, as well as retaining wall blocks formed by such processes. The invention permits the front face of the block to be impressed with a pattern or otherwise directly processed, to allow the formation of pre-determined block front faces, while at the same time facilitating high-speed, high-volume production of blocks. Pre-determined front faces can include front faces having pre-determined patterns and textures, front faces having pre-determined shapes, front faces made from different material(s) than the remainder of the block, and combinations thereof.	11-12-2009

20090123228	CABLED MAT SYSTEM WITH REMOVABLE BLOCKS - A mat system includes a surface and at least first and second mat units. Each mat unit includes a respective plurality of blocks interlinked by respective cables that pass through the blocks. Each mat unit includes cable loops along at least one side section thereof. The first and second mat units are positioned on the surface in proximity to each other with cable loops of the first mat unit extending toward the second mat unit and cable loops of the second mat unit extending toward the first mat unit. A plurality of interconnecting blocks are positioned between the first mat unit and the second mat unit. Each interconnecting block includes an underside with downwardly open channels formed therein. The cable loops of the first and second mat units are positioned within the channels of the interconnecting blocks to cover the cable loops. The interconnecting blocks and the blocks forming the first and second mat units are sized, shaped and positioned such that upper surfaces thereof form a substantially continuous surface.	05-14-2009
