Abstract: An improved flatwork concrete finishing apparatus includes a side-by-side pair of parallel spaced elongate brush assemblies, each brush assembly having an elongate head with a pair of upper corners or stops, a downwardly directed throat with opposing inwardly directed grooves, and a plurality of replaceable elongate blocks, each having at least one row of color-coded bristles with a stiffness different than the bristles of at least one of the other blocks. Each of the blocks have outwardly directed ridges adapted to be slidably received by the grooves. A plurality of corresponding pairs of brackets attached to each of the pair of brush assemblies are interconnected by a plurality of spacers pivotally connected thereto.

Abstract: A collapsible traffic control assembly comprising a plurality of cylindrical segments selectively positionable relative to one another into a secured outwardly extending operative position or collapsed position wherein the segments are concentrically disposed within a housing. The housing of the assembly is adapted to allow a nesting stacked array of a plurality of such housings when the cylindrical segments associated therewith are disposed in their stored position.

Abstract: The present invention is directed to a bollard made of an elongate member having a lower proximal end biasedly attachable in an upright position to a path surface, an upper distal end, and a longitudinal axis. A collar is attached to the elongate member about its upper distal end. The collar is rotatable about the longitudinal axis of the elongate member. When such bollard is mounted on or adjacent a path surface, the bollard is deflectable from its upright position about its proximal end, e.g., when contacted by a vehicle. The collar rotates when in contact with the vehicle for following the contour of the vehicle without damaging the vehicle. Specific bollard configurations are disclosed herein along with numerous attachments with which the inventive bollard can be outfitted.

Abstract: An Aqua-Blok that fits into a frame or cone of a manhole directly beneath the cover, in the frame below the cover or within the cone to catch water that seeps into the manhole. Aqua-Blok is a polyurea, flexible bowl that rests on the frame directly under the cover or is mounted in frame or the cone. When used in the lower frame, it has a closed cell gasket on its outer top side, and an adjustable stainless steel ring on its inner circumference to press it against the frame. When Aqua-Blok is placed in the cone, it uses a rubber mount placed within the cone to mount Aqua-Blok. The rubber mount has a core with concentric rubber rings on its outer periphery that match the sloped sides of the cone. It has a circular cavity in its inner circumference to receive the pressure ring. The pressure ring forces the core and the concentric rings against the wall of the cone in a watertight fit. The bowl is seated on the mount where it catches any water that flows into the manhole from above it.

Abstract: A holding device for paving blocks which has a vertical side for contacting the paving stones is strongly buttressed to hold the paving blocks. At pre-selected points along the vertical side are belts of material perpendicular thereto. Buttressing each belt of material in the vertical edge are gusset members supported by a boss member. The boss member provides for driving a nail into the ground and through the support member in order to hold the holding device for paving blocks in position. The nail is a barbed X-cross-section nail which may be used to secure the holding device for paving blocks.
