Abstract: An elongated building block has spaced apart inner and outer faces and top and bottom faces and complementary end portions with openings therein. The openings of the block are disposed on a straight longitudinal axis and clearance is located adjacent the longitudinal axis and a central portion of the inner face of the block. When horizontal rows of similar blocks are stacked one upon the other, end portions of the blocks in one row are positioned above central portions of blocks in an adjacent row, so the joints between the blocks are staggered. Generally vertical connecting rods pass through aligned openings to connect alternate rows of the blocks together. Clearance in alternate rows of blocks exposes intermediate portions of the connecting rods. When used as an embankment retaining wall, generally horizontal tie back rods embedded in the embankment connect with the exposed intermediate portions of the connecting rods passing between alternate rows of blocks.

Abstract: A device for playing games comprising a body portion having a plurality of angularly spaced-apart, generally T-shaped members extending therefrom. The members may be asymmetrically spaced around the body portion.

Abstract: The invention provides for a process for constructing manhole assemblies in an excavation or elsewhere, by the utilization of an outer form, a preformed manhole barrel which is positioned and propped within the outer form pipe stub inserted partially into the inside of the preformed manhole and resting under notches cut into the preformed manhole barrel, inflatable or rigid forms (or both) are used to form simple or complex channels in the concrete which is to be poured. The form ends are adapted to fit into the pipe stub ends or may abut other forms, where complex channels are desired. The forms are carefully positioned to allow for the proper height and grade of the channel in the completed manhole assembly. Concrete is poured and when it is set, the forms are deflated where applicable and removed to be reused.
