Abstract
A method of dynamic representation using a support, a removable reference sheet secured to the support and bearing at least two inscribed parameters or variables, movable members for mounting on the sheet by detachable magnetic attachment with the support, and a photo-copying apparatus. The members can be mounted on the sheet in a succession of different positions according to pairs of variables. The support is turned upside down after each positioning of the members and photocopied in order to obtain a succession of instantaneous representations of parts of a dynamic process.
Claims8
A method of dynamic representation of information which comprises providing a frame having a back comprising a sheet of magnetic metal, a rim fixed to said back and having an opening defining a window, a reference sheet overlying said sheet of magnetic metal and visible through said window, said reference sheet having indicia thereon, placing on said reference sheet in selected position thereon a plurality of movable members of selected size, shape and color, said movable members having permanent magnetic properties whereby said members when placed in selected position on said reference sheet are attracted by said underlying sheet of magnetic metal and thereby held on said reference sheet in the position in which they are placed, turning said frame with said reference sheet and said movable members thereon face down on the window of a photocopying machine and operating said machine to make a photocopy of said frame with said reference sheet and said movable members thereon, said rim projecting forwardly from said back beyond said movable members on said reference sheet whereby said rim rests on the window of the photocopying machine and holds said movable members out of engagement with said window to avoid displacement of said movable members on said reference sheet.
Apparatus for dynamic representation of information comprising:
- a frame having a back comprising a sheet of magnetic metal,
- a rim fixed to said back and having an opening defining a window,
- a reference sheet overlying said sheet of magnetic metal and visible through said windown, said reference sheet having indicia thereon, and
- a plurality of movable members of selected size, shape and color, said movable members having permanent magnetic properties whereby said members when placed in selected position on said reference sheet are attracted by said underlying sheet of magnetic metal and thereby held on said reference sheet in the position in which they are placed when said frame is placed face down on the window of a photocopying machine,
- said rim projecting forwardly from said back beyond said movable members on said reference sheet, whereby said rim rests on the window of the photocopying machine and holds said movable members out of engagement with said windown to avoid displacement of said movable members on said reference sheet.
