A concrete form for holding a concrete product in place during a curing process with at least one side movable by a rotary driven power source and a actuator. A rotary power tool with a helical cutout combinable to a second adapter on the rotary driven power source to rotate the rotary driven power source to power the actuator and move the at least one side.

A method of forming simulated stone or brick column or a retaining wall is made up of rows of masonry blocks of generally trapezoidal configuration arranged in end-to-end relation to one another in each row, each block including a recessed portion being aligned with one another in each row and each block having textured wall surfaces simulating the appearance of brick or stone along one or more wall surfaces arranged in different configurations without the necessity of interlocking the blocks together.

A machine (1) for the additive manufacture of a component (2) by complete or partial selective melting of a powder comprises: a working chamber (100); a sleeve (3) having a top opening (4) opening into the working chamber (100), and having a vertical central axis (5), a support plate (6) intended to accept the component (2) in the process of being manufactured, a device (7) for actuating the translational movement of the support plate (6) inside the sleeve (3) along the vertical central axis (5) of the sleeve (3), and a component (2) extraction system (8) comprising a container (9), the extraction system (8) further comprising at least one closure plate (12) that is able to move in order to close the bottom opening (15) of the container (9), and the attachment between the support plate (6) and the actuating device (7) being of the removable type.

A modular assembly is provided for managing the flow of fluid beneath a ground surface. The assembly can feature a plurality of modules, each having a deck portion and opposing sidewalls extending downward therefrom. The opposing sidewalls can slope outward and away from one another as they extend downward from the deck portion. The modules further comprise a shoulder for supporting a link slab, and to support and separate modules that are stacked during transportation or storage. The sidewalls can define an interior fluid passageway having a flared configuration from top to bottom. The link slab and sidewalls of adjacent modules can define an exterior fluid passageway in fluid communication with a lateral fluid channel. A method is also provided for making a precast concrete module for use in the modular assembly.

A form for separating a concrete block and a method for separating a concrete block from the form. The formed concrete block remains stationary while the doors of the form are pulled away from the concrete block in order to more conveniently, efficiently, and safely obtain access to the formed concrete block for its removal.
