An apparatus and method for a reel-to-reel chalk line comprising a first housing comprising a first reel, a first rotatable crank mechanism connected to the first reel, and a first chalk bin comprising apertures for allowing the passage of a continuous impregnable chalk line. The apparatus further comprises an opposed second housing comprising a second rotatable reel, a second crank mechanism connected to the second reel, and a second chalk bin comprising apertures for allowing passage of the continuous impregnable chalk line. The continuous impregnable chalk line is reeled about the first and second reels as the respective crank mechanisms are alternately rotated forward and backward. The chalk may include a variety of substances including powders, reactive powders, liquids, dyes, glass, minerals, plastics, ceramics, metals, and fibers. The continuous chalk line may comprise interconnected impregnable chalk lines joined by mechanical or chemical means forming the continuous impregnable chalk line.

The invention relates to a portable device for marking a surface, including a casing (2) having a front face (6) having a rectangular opening (6A) for the passage of a marking member, the front face (6) of the casing being provided with a stiffening frame (15) surrounding the passage opening (6A), this stiffening frame (15) being provided with an indexing system (18) adapted to cooperate with a complementary indexing system (19) equipping each of the tooling of a series of removable tooling (20A, 20B, . . . ) for positioning the device on the surface to be marked, each removable tooling (20A, 20B, . . . ) of the series and the stiffening frame (15) including at least one of the elements of a magnetic fastening system with two elements, namely a magnet (21A) and a ferromagnetic material (21B).

An alignment head for an automatic fastener feed installation tool employs a platform with spring biased retractable pins and a central opening. The retractable pins are spaced to protrude downwardly and engage opposing sides of a support joist. The central opening receives the fastener which is automatically positioned for driving at an entry position into a deck board overlying the joist. The fastener is drivable into the joist at a medial position of the joist and a pre-established position from the edge of a deckboard. The pins also define the spacing of the adjacent deck board. In one embodiment, the alignment head is employed for securing the deck boards at a consistent 45° angle to the joist.

A mobile printing robot includes a windbreak to reduce wind-induced deflection of ink droplets emitted from a printhead of the mobile printing robot. The printhead may have a comparatively large throw height to aid in permitting obstacles, such as particles from safely passing under the printhead without damaging the printhead or cause the printhead to become stuck. The windbreak may be implemented using resiliently compliant sections that block the wind but accommodate the passage of particles or other obstacles.

A marking gun having a marker container, a propellant canister, a supply tube, an expulsion chamber, and an attachment coupled to the expulsion chamber. The marker container is coupled to the expulsion chamber by the supply tube, and the propellant canister is coupled to the expulsion chamber. The marking gun is configured to expel the marker from the expulsion chamber. The attachment comprises a stencil, an elastic pointed tip, a housing, a screen, a magnet, one or more entry holes, or a combination thereof.

The disclosure presents templates that can be useful in construction. Embodiments of the templates include a face, and two or more indicators. The indicators are located at one or more predetermined intervals on the face, and each indicator defines a window. Each window is of a predetermined length, and each indicator is coded to indicate that each indicator is located at one of the one or more predetermined intervals.
