    Abstract: Single and multiple retaining wall blocks and block systems are disclosed. The blocks are provided with a face connection system which includes at least one front lip extending from a top surface of the block and a bottom channel formed into a front face and bottom surface of the block. The front lips have a length which is less than the width of the blocks.

    Abstract: A system of blocks is configured to be compatible with each other in the construction of a columnar structure. Each block has four faces and all four faces may generally have the same dimensions. The width of the blocks may generally be about twice their height. The faces of the block also may contain a slot to add an aesthetic appearance to the column. The blocks have certain constructions features that mate with specially constructed brackets in attaching a fence panel to the completed column. The blocks have interlocking elements or projections that permit positive connection between courses of blocks. Projections of one block extend into the core another block. Adjacent blocks can be rotated 90 degrees relative to each other about a vertical axis of each block with each course. The blocks can be used to construct a column that is easy to install and structurally sound.

    Abstract: An apparatus, method, and system for generating pressure pulses in a drilling fluid flowing within coiled tubing assembly is described that includes; a flow throttling device longitudinally and axially positioned within the center of a main valve actuator assembly that allows main exit flow fluid to flow past a drive shaft and motor such that the pilot fluid and the main exit flow fluid causes one or more flow throttling devices to generate large, rapid controllable pulses. The pulses generated by the flow throttling device thereby allow transmission of well-developed signals easily distinguished from any noise resulting from other vibrations due to nearby equipment within the borehole or exterior to the borehole, or within the coiled tubing assembly wherein the signals also provide predetermined height, width and shape of the signals.

    Abstract: A method of making a wall block and a mold box therefore. The wall block design maximizes the use of the mold box. The method produces wall blocks having a large surface area front face compared to the front face size of prior art blocks. The blocks have about one third more front surface area. This results in faster construction of walls and a faster construction sequence. The method of making the blocks makes efficient use of mold space and material, resulting in higher production yields and/or higher total daily production square footage.
