Abstract: A corner block and a wall block system with a corner block for forming in multiple courses a wall which includes first and second visible wall portions which meet at a corner and where the corner block has a front face and at least one side surface having a texture or pattern matching the texture or pattern of a front face of a first block of the wall system.

Abstract: 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.

Abstract: A wall block, wall block system and method of making a wall block. The wall block including at least one core extending from the top surface to the bottom surface, the at least one core having opposed front and rear surfaces and first and second side surfaces the wall block also including at least one pin hole opening onto the top surface of the block and extending at least a portion of the distance from the top surface to the bottom surface. The at least one pin hole may open onto at least a portion of at least one surface of the at least one core. The block may be provided with channels; the pin hole, channels and core may all be formed in a mold box by a single forming member.

Abstract: 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.

Abstract: A veneer panel system is used with a wall or a retaining wall to provide a natural stone appearance and/or to improve the appearance of an existing wall. Panels can be interlocked to form a stable veneer structure. The structure is attached to a wall by various attachment devices.

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: Single and multiple retaining wall blocks and block systems in which 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 equal to the width of the blocks.

Abstract: An apparatus for a heating, ventilating and air conditioning system may include an outer shell and a honeycomb structure. The outer shell may define an interior volume having an inlet and an outlet providing an airflow path therethrough. The honeycomb structure may be attached to the outer shell and disposed in the airflow path. The honeycomb structure may include a plurality of polygonal apertures extending substantially in a direction of the airflow. The honeycomb structure may deflect sound waves away from a predetermined area.

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 thereby allowing 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: An apparatus, method, and system described for generating pressure pulses in drilling fluid utilizing a flow throttling device which includes a controllable pulser operating sequentially within a downhole assembly within a drill string of a drill pipe. The system includes drilling fluid, fluid flow, and fluid drilling pump which when combined creates fluid flow into a bore pipe annulus within the downhole assembly creating a base line bore pipe pressure wherein bore pipe pressure is sensed via a sensor and information is sent to a Digital Signal Processor (DSP) that interprets the information. The DSP also receives information from an annulus pressure sensor that senses drilling fluid pressure as it returns to the pump. The DSP recognizes pressure variation input from the annulus pressure sensor and bore pipe pressure sensor and detects pressure variation providing signals as data information to the DSP, determining required action to adjust pulser operation.
