Abstract: A novel cable anchor for retainment and attachment of cables and tubing which utilizes a one-piece A-shaped rigid body (11) comprising of a U-shaped top (12) having the front, back and bottom open having two extensions one W-shaped left side extension (13) and one W-shaped right side extension (14) both extensions extending in a downward direction having 40 degrees more or less between the extensions. The W-shaped extensions having a barb surface located at the extreme outer surfaces of the W-shape. The U-shaped top (12) having an attachment hole (15) located at the top center. When manual pressure is applied on the outer surfaces of the extensions causing the extensions to move closer towards each other until the extensions are touching each other in the closed position thereby allowing the A-shaped rigid body (11) to be received in a bored hole of a substructure. The U-shaped top (12) may be flattened to facilitate the attachment of a separate cable clip or the like.

Abstract: A novel cable clip for retainment of cables or tubing which utilizes a one-piece J-shaped rigid body (9) comprising of a cupped shaped bottom (10) having both ends open, a short side (11) having a locking device located at the end of the said short side (11), a long side (12) having a locking device located at the unattached end of the punched-out projection surface (13), said punched-out projection surface extending in a downward direction pointing towards the said short side locking device and being part of said long side (12). At the upper end of said long side (12) having an attachment hole (14) having a mechanical device for attachment of said J-shaped rigid body (9) to a substructure. The said J-shaped rigid body (9) can be flexed repeatedly along the surface of both the short side (11 ) and long side (12) where they become common with the cupped shaped bottom (10) without fracturing, allowing the locking devices to interlock repeatedly and to disengage repeatedly.

Abstract: A production line, continuous feed, high volume output apparatus for cutting, grinding, and/or polishing concrete or fired masonry units into finished masonry building materials. A conveyor belt moves the masonry units from an input station through a processing station where the masonry units are subjected to abrasion treatment by a rotating working head. The working head may take the form of saw blades or one or more horizontal cylindrical drums disposed above the conveyor path with the axis of the horizontal cylindrical drums normal to the conveyor path. The height of the working head above the conveyor path is adjustable. In the drum form of the working head, an abrasive, such as synthetic diamonds is mounted in a matrix in a spiral array. Lateral movement of the masonry units off of the conveyor path is restrained by adjustable guide rails.
