United States Patent Office 3,316,660 Patented May 2, 1967 3,316,660 LAMINARFORM FOR USE WITH ELECTRO-STYLUS Joseph Greenspan, 1120 Queensland St., Los Angeles, Calif. 99634 Filed Get. 12, 1965, Ser. No. 495,221 9 Claims. (Cl. 315-9) This invention relates -to self-examination devices of the type wherein an electrically operable probe is intelligently applied to areas of like appearance and of predetermined conductive and/or non-conductive capability. Particularly, this invention is concerned With improvements in such a device and with improvements of such magnitude that such a device becomes feasible for practical applications.

The art relating to this invention is redundant with ways and means t-o accomplish the obviously desired end result. However, despite previous attempts to produce such devices on a commercial basis there have been repeated failures, and in this respect reference is made lto the cumbersome board like structures of the prior art and t-o the use of so called selective electroconductive and non-conductive inks. The first mentioned example of Iboard like structures is eliminated from utility in considering the present invention because they are not condusive to the assembly and normal handling of books and pamphlets and pages, which is the objective of this invention. The second -mentioned example of sele-ctive electro conductive and non-conductive inks has `been tried by the industry involved, and is now discarded `because such inks impregnated with conductive materials could not be applied successively with predictable characteristics. l

As above indicated, it is a primary object of this invention to provide predetermined Vareas of identical appearance, some of which are electrically conductive `and some non-conductive, in printed matter adapted to be used as papers and/or pages of books and the like.

It is an object of this invention to provide papers and/ or pages of .the character referred to wherein like openings are formed in the paper or page so as t-o visably expose a film of electrically conductive material, predetermined areas ofthe lm being non-conductive.

It is still another object of this invention to provide laminarform paper or pages as hereinabove referred to and which can present printed matter at both sides and each side of which exposes identically apparent areas of predetermined electrical conductivity.

The various objects and features of this invention will lbe fully understood from the following detailed desecription of the typical preferred form and application thereof, throughout which -description reference is made to the accompanying drawings, in which:

IFIG. 1 is a perspective view of a book employing the laminarform pages.

PIG. 2 is a fragmentary view of the top portion of a typical laminarform page as employed in a book as shown in FIG. 1.

FIGS. 3 and 4 are enlarged detailed sectional views taken substantially as indicated by lines 3 3 and 4 4 on FIG. 2.

In accordance with the presen-t invention resort is made to a laminarform structure, whereby predetermined areas of conductive and/or non-conductive material are exposed so as to be identical in appearance. The invention is particularly adapted to be embodied in the printing of pages and papers, in the manner that pages and papers are ordinarily printed. That is, the use of relatively thin flexible paper is to be made, and because of the lamin-arform employed it is feasible to minimize the several paper thickn-esses. Paper is specified herein as the preferred material, being the usual paper employed in printing, yand because it is a good insulator in itself. However, substitutes for paper can be made as circumstances require.

The laminarform involves, in its basic form, at least two layers of material upon which selectively placed and discriminately shaped deposits have been applied. The first or top layer is substantial and durable while the second or underlying layer is not necessarily as substantial and consequently not as durable; and therefore the laminarforrn involves, in its preferred form, three layers of material, the first and second as hereinabove set forth and third layer corresponding to the first mentioned layer but placed at the opposite or underlying side of the laminarform, Thus, the said laminarform is two sided, being -comprised of two like layers of durable paper with an intermediate layer of electrically conductive material. In practice, all three layers are coextensive one with the other, and as is illustrated the laminarform involves generally, top and bottom lamina A and A' and an intermediate lamina B.

The la'minae A and A are essentially alike or identical and each is a sheet of minimal thickness, taking into account that they are to be combined so as to afford the strength of the two sheets. Each sheet 10 has an outer face 11 adapted to receive indicia :and printed information 12, and an inner face 13 adapted to be wetted with an adhesive. IFor example, the indicia 12 can be a statement of facts followed by a question, as is shown. In accordance with the invention, the sheet 10 is perforated at 1S so as to provide an opening therethrough of substantial area. For example, the indicia 12 may or may not require treatment of the area represented 'by the perforation 15, and as is shown might require the intelligent consideration of a multiplicity of answers as is evidenced 'by indicia 16 at each of said openings. In any case, the intelligent recognition of the indicia 12 requires treatment of one (or perhaps more) of the areas represented by the .perfo-rations 15. The indicia 12 and-16 are preferably printed matter that are reproducible in large quantities of paper sheets 10.

The intermediate lamina B is essentially a film of conductive material such as aluminum foil 20 and which is a good electrical conductor. The said foil 20 is mechanically Weak and tends to be soft, but is reinforced when laminated with the laminae A and A. Such foil is selected for its bright appearance, and for its tendency to remain uniform in appearance. In accordance with the invention the electrically conductive foil 20 is covered in predetermined areas only, with a transparent dielectric coating 21, the coating 21 being placed so as to register coextensively beneath certain perforations 15. For example, the coating 21 completely avoids one of said perforations 15 which represents the correct answer to the indicia 12. In practice, a satisfactory coating 21 is clear lacquer which can be conveniently deposited upon the lamina B within discriminate areas as by means of silk-screen processes. The lacquer coating is substantially colorless and presents a visible surface which is of the same smoothness and texture as that of the surrounding and underlying foil surface, all to the end that the presence of the superimposed lacquer coating 21 is not discernable.

In practicing the present invention, the laminae A, A and B are each fabricated as above described and laminated to form a single element. As is shown, there are one or more openings (perforations) 15 in each lamina to be viewed and in this instance both top and bottom sides. It is a simple matter to offset the openings at the opposite sides of the laminarform structure, thereby providing backing for the element B. That is, the hardness of the opposite sheets presents a backing at opposite openings. In view of the above, the two or three elements A-B, as the case may be, are of course rotatably oriented and printed and/or coated in register with each other, and they are then adhered together in said rigid engagement. Any suitable adhesive (not shown) is applied to the inner faces 13 of the elements A and A whereupon the elements A-B are brought together and bonded to each other. Thus, the lamina B is exposed through the various perforations 15 and only the uncoated areas are conductive, while all of said areas appear identical in appearance.

The instrument for detecting conductive as distinguished from non-conductive areas is an elongate battery 30 operated light 31 having projecting contacts 32 for intelligent selective engagement with the conductive foil of the lamina B. It is a simple matter to establish continuity with the circuit shown, by touching the contacts to the conductive surface Where it has not been dielectrified by the application of the transparent coating.

From the foregoing it will be seen that a normally flexible laminarform paper or page is provided and wherein both sides thereof are equally utilitarian. Rather than resort to conductive inks and the more cumbersome switching structures, resort is made to a conductive intermediate foil which is exposed at suitable areas, some of which are made non-conductive by the application of a superimposed transparent insulator. The insulator does not alter the color or texture of the otherwise bright metallic surface of the foil, and to the end that a person viewing the same is not influenced in his choice of an area, and he must therefore rely entirely upon intelligence in applying the instrument in proving up his choice.

Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any modifications or variations that may appearto those skilled in the art and fall within the scope of the following claims.
