A quilting template system and a method for selecting a template to facilitate quilting a border-like area of a craft-work with length-sides and width-sides meeting at corners. The template system includes a set of templates each having an edge of repeated patterns of equal pattern-length but differing in pattern-length from template to template, and a correlator indicating which template(s) of the set are usable for the craft-work without fractional-pattern use on either the length-sides or the width-sides thereof. The method includes a sequence of steps for selecting a template by using the correlator to indicate which templates are usable for quilting the entire border-like area without fractional-pattern use. The system preferably includes groups of templates, templates of each group each having patterns of equal pattern-length but differing in pattern-shapes from template to template within the group. Another aspect of the invention involves assemblages of templates on trays in uniplanar organized arrangement with adjacent templates having complementary edges. Yet another aspect involves a template for establishing a continuous stitch-line of repeated portions each with halves of inverted symmetry.

A method for forming a topographical image of the heterogeneous variations in a surface of a material has a first machining step and a second scanning step. The preferred machining step uses a preselected scribing tool to scribe a plurality of adjacent grooves in a selected material surface at a preselected constant force. This machining step produces a machined surface whose local elevations relative to a datum plane are dependent on the local hardness or wear resistance of the surface. Then the scanning step shifts the scribing tool across the surface in contact with the surface, and measures the elevation of the tool at a plurality of selected surface coordinates. The measured elevations allow formation of a topological map depicting sub-micron structural features of the surface.

A programmable marking scribe having a material displacement stylus movable in three mutually orthogonal axes to displace material from an object being marked and create a two-dimensional matrix of recessed areas formed of grooves and surrounded by ridges, the grooves and ridges forming a reflectively multifaceted data cell having a collective reflectance that is in contrast with unmarked surface reflectance to enable a reader to clearly distinguish the former from the latter even in the presence of extraneous interfering marks and deposits.

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.

A corner bracket having a base member and a first wall attachment portion that extends substantially perpendicular to the top side of the base member and a second wall attachment portion that extends substantially perpendicular to the top side of the base member, such that a first wall attachment surface of the first wall attachment portion is perpendicular to a second wall attachment surface of the second wall attachment portion. A central bracket member, an inner bracket member, and an outer bracket member each extend from the top side of the base member. The central bracket member is positioned substantially between at least a portion of the inner bracket member and the outer bracket member and a base member edge, two opposing central bracket member edges, an inner bracket member edge, and an outer bracket member edge are each aligned.

A fence for guiding a work surface past a saw blade supported by a table having a support tube running substantially perpendicular to the saw blade. The fence includes a rip fence having a plurality of studs disposed on opposing sides thereof. A pair of fence faces are positioned on opposing sides of the rip fence and have a plurality of slots for removably engaging the studs thereby securing the face fences to the rip fence. A rip fence head is affixed beneath the rip fence. A lockdown clasps the support tube with the rip fence head for securing the fence to the tablesaw. The lockdown includes an adjustment mechanism for stabilizing the fence to the support tube independently of the lockdown. The adjustment mechanism is adjustable relative to the lockdown so that the position of the fence on the support tube can be accurately adjusted by moving the fence relative to the lockdown mechanism.

A drawing apparatus is provided. In the apparatus plural drawing tools for applying ink on an object are held by plural drawing tool holding units respectively. A drawing unit takes one of the plural drawing tools from the plural drawing tool holding units to draw an image on the object. An imaging unit images an identification image, which includes first information representing colors of inks to be applied respectively by the plural drawing tools and second information representing an arrangement of the plural drawing tools held in the plural drawing tool holding units. A controlling unit controls the drawing unit to draw a design image having at least one color on the object, based on the first and second information included in the identification image and the color of the design image.

A drawing apparatus including a drawing head to which a drawing tool is mounted, the drawing tool drawing on a drawing object; a drawing testing portion having a drawing media on which an image is drawn by the drawing tool; and a control unit.The control unit interrupts drawing on the drawing object by the drawing tool and attempts drawing on the drawing media by the drawing tool in the drawing testing portion when the drawing on the drawing object by the drawing tool is not performed correctly.
