Reference marks may be provided on the pattern and associated with each possible axis of alignment for indicating an absolute dimension of a concurrently projected or printed figure. To conserve space, the pattern may be "densepacked" with scaling figures such that each scaling figure includes a plurality of opposing edges, each alignable along a different axis in response to different levels of dimensional distortion.

Abstract: Indexing overlay for computer display devices such as CRT's and plasma displays. The overlay consists of a sheet of hi-static vinyl, acetate or the like of a size to conveniently cover the display area of columns and rows of discrete displayable positions. The sheet is of a thickness so that the overlay can be electrostatically attachable to the face of the display device. A set of first indicia defined discrete columnar positions along a row. Another set of indicia break up the first indicia into discrete fields five indicia wide. One set of labeling indicia accumulatively number the columns from left to right and a second set of numbering indicia may be used to accumulatively number the rows from top to bottom. The indicia are imprinted in reverse on the back side of the sheet in black or bright color ink. The color is selected to give high contrast to the indicia against the type of display background upon which the overlay is used.

Abstract: A duplicating stencil has its heading strip in the form of two separate regions separated by a perforation line.The holes on one region have a different arrangement from those on the other regions, so that tearing along the perforation line allows one region to be separated from the rest of the stencil and to leave the holes of the remaining region as the effective mounting holes.A single image field and a single top edge guide line apply for all of the heading strip regions.

Abstract: A drafting template having printed thereon a pattern of non-concentric elliptical portions, preferably forming complete ellipses, a vertical measuring line extending upwardly from a common point for the pattern or from a base point for the vertical measuring line, and a horizon line mounted at a scaled height above the base point and being parallel to the major axes of the elliptical portions or ellipses. The pattern is a perspective view of concentric circles or portions thereof taken at a scaled distant station point and scaled height above the plane for the circles. The horizon line is mounted at a scaled height above the base point. By selecting one or more vanishing points on the horizon (line), and drawing lines on an overlaying drafting sheet correlated to the base point between the vanishing point(s) and base point, such drawing lines intersecting the elliptical portions or ellipses, a lined grid field can be ultimately produced on the drafting sheet.

Abstract: A novel course correction calculator, consisting of a sheet of transparent material 1 with inscribed reference line 2, centering points 3 and 4, radial lines 5 and 6, circular arcs 7 and circles 8, is provided whereby a heading correction and a speed correction factor for true speed can be obtained quickly and easily by a navigator for a small boat, vessel or aircraft, that offsets the effects caused by the motion of the medium through which the craft is traveling, such as tide or wind.

Abstract: An instrument and method is provided for accurately determining the geographic coordinates of a specific location on a map. The instrument comprises a flat transparent plastic sheet having a variable length scale printed thereon which is defined by a plurality of straight lines radiating from a common point. Indicia are also printed on the sheet for designating the radiating lines as graduations of a scale comprising either 2.5 or 5 minutes, and with each minute being further broken down into sixty seconds. To determine a coordinate, the location in question on the map is projected to the border along a direction parallel to one set of the geographic coordinates. The transparent sheet is then placed over the map, and the scale is aligned with respect to the border such that the outermost of the radiating lines directly overlie the tick marks on the map between which the projected location falls. The scale is then read above the point at which the projected location intersects the border of the map.
