Engraving tool bit depth controlling nosepiece adjustment devices establish a precise protrusion distance that an engraving tool bit protrudes from the end of the nosepiece of a spring loaded engraving tool, that is in turn inserted within and driven by a standard machine tool such as a cnc type milling machine. One rotational adjustment device establishes the axial position of the nosepiece with respect to a collet nut of the engraving tool and another adjustment device employs annular ring spacers in the form of washers between the nosepiece and collet nut to precisely establish the desired engraving tool bit protrusion distance from the end of the nosepiece. This modification of a spring loaded engraving tool beneficially prevents the engraving tool bit from being able to plunge too deeply into the workpiece, particularly at the start of each engraved line, to thus ensure that all the lines will be consistent.

A marking device or scribe for marking masonry pieces on a horizontal deck area surrounding a pool, sauna or similar below-ground construction. The device is designed for use during construction of deck areas to enable defining a border or margin a constant distance from a curved vertical edge. This marking facilitates subsequent cutting of the marked masonry pieces for removal and construction of a more aesthetic edge border. Device guide wheels follow curved vertical walls of the pool and guide a frame and attached marker that is supported on wheels on the deck. The marking device is biased against the masonry pieces to create a path line mark as the frame and guide wheels are manually move along the edge.

A cutting plotter equipped with a device for reading register marks for seal cutting capable of accurately reading the register marks printed on a seal material. The cutting plotter includes a head provided thereon with a light emitting element for emitting a predetermined amount of light toward a surface of the seal material and a light receiving element for detecting the amount of light reflected from the surface of the seal material. A difference between the amounts of reflected light detected by the light receiving element is calculated by a first calculation unit and then stored in a storage unit. A relative difference between the difference in the amounts of reflected light stored in the storage unit and a difference between the amounts of reflected light calculated by the first calculation unit is calculated by a second calculation unit. Also, a determination unit is arranged so as to determine whether or not the relative difference calculated by the second calculation unit is within a predetermined tolerance, to thereby determine whether or not the register marks are printed on the seal material.

The server transmits the session manifest to the smart appliance.

A masonry line block is adapted for use in combination with a vertical corner pole during construction of a structure. The structure has an exterior surface and at least one surface projecting from the exterior surface. The line block engages the corner pole at one end of the structure and cooperates with a line holder located at an opposite end of the structure to carry a tensioned guide line therebetween. The guide line indicates proper placement and alignment of building units used to form the structure. The line block includes a mounting member having first and second, opposing pole-engaging shoulders. The shoulders are adapted for selectively engaging the corner pole to hold the line block in one of first and second alignment positions relative to the structure. An alignment member is formed with the mounting member and extends perpendicularly outwardly from the pole-engaging shoulders. The alignment member has first and second opposing sides and defines a thickness corresponding generally to a distance between the outer surface of the structure and the projecting surface of the structure. In the first alignment position of the line block, the alignment member is adapted for locating the guide line relative to the structure to indicate proper placement and alignment of building units used to form the exterior surface of the structure. In the second alignment position of the line block, the alignment member is adapted for locating the guide line relative to the structure to indicate proper placement and alignment of building units used to form the at least one projecting surface of the structure.
