Abstract: The present invention relates to the field of typography. In this field, it is desirable to quickly and efficiently determine certain key ratios between cap height and type size of a letter in a particular typeface, in order to create various aesthetic results. In situations where variations in typeface height normally cause problems, such as: matching specimens of typeface; filling vertical spaces; and dropping caps, among others, the task of determining this ratio is complicated by the fact that typefaces with the same point size may actually differ in height, and typefaces of the same name may vary in size according to the typesetting system which produces them. In such situations, the instant invention is particularly useful.

Abstract: A drawing apparatus is disclosed for guiding the continuous drawing of two intersecting lines with interconnecting curved corner portions. The apparatus comprises a set of rulers which intersect one another at a desired angle of 90.degree. or less to define thereby a corner. A guide is provided for guiding the continuous drawing of two intersecting lines with the curved corner. The guide has a base portion with an external edge. An aperture extends through the base and has an interior edge of a shape to define the desired curved shape for the corner. The guide remains stationary in the corner defined by the rulers to cause a drawing instrument to follow the interior surface of the aperture in continuously drawing a curved corner of desired shape from a first line merging into a second intersecting line.

Abstract: A needlework guide includes a sheet steel backing and a sheet steel frame defining a central, rectangular window therein. A picture to be produced in needlework is positioned on the backing. The picture is either superimposed on graph paper or a transparent overlay with a rectilinear grid thereon is positioned thereover. Magnetic strips hold the frame to the backing with the picture and any transparent overlay sandwiched therebetween. Vertical scales are positioned along opposite sides of the window with graduations equal to the spacing of the rectilinear grid and with numbers corresponding to the weft row to be woven. A horizontal scale also has graduations spaced at the same interval and duplicate sets of numbers ascending in both directions from the center of the scale. The numbers on the horizontal scale correspond to the warp yarns to be woven. Different colors of yarns are woven in correspondence with the colors on the image mounted between the frame and the backing.

Abstract: A multi-element aid for the design of business forms of different sizes having selectable characteristics. As disclosed, the business form design aid includes four elongated elements slidably interconnected to form an enclosed, generally rectangular area of variable size. Each element includes a border guide marking, which is aligned with the inner edge of one adjacent element, as well as one or more business form indicia spaced apart from the border guide marking along the element. The inner edge of each element also meets a border guide marking on a second adjacent element. In this way, for any interior opening size, selectable business form design indicia are spaced apart from each of the inner edges of the four elements by consistent distances.

The ratio of the index on the first edge to the corresponding index on the second edge is also the same as the field ratio. The index on the third edge is defined by the projection thereon along a line parallel to the first edge, of the index on the second edge.
