Abstract

Abstract This invention relates to fiber optical image transfer and magnifier devices and their method of manufacture. More specifically the magnifier device is of the spaced fiber array type with constant light conducting fiber cross section. The fiber endings on the magnifier screen are spaced by an interstitial metal matrix which is formed by a casting process. The casting mould is made of an aperture plate on the bottom, and it is enclosed by side walls. The fibers are threaded thru the aperture plate holes and are hence located and held in position for casting. Fibers are fed through the aperture plate from spools. The casting is pulled out of the mould, with its fibers attached to it, to the desired length, then another casting is made. The input screen is produced by the use of movable fiber guides and a compression die.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 223 words
A METHOD OF FABRICATING A FIBER OPTICAL IMAGE TRANSFER AND MAGNIFIER DEVICE COMPRISING: THREADING A PLURALITY OF LIGHT CONDUCTING FIBERS THROUGH AN ORDERLY ARRAY OF HOLES IN AN APERTURE PLATE FORMING THE BOTTOM OF A MOULD CAVITY; CASTING AN INTERISTITIAL MATRIX BY POURING A LIQUID MATRIX MATERIAL INTO SAID CAVITY AND SOLDIFYING THE LIQUID; REMOVING SAID MATRIX FROM THE MOULD WHILE MAINTAINING THE PLURALITY OF ATTACHED FIBERS INTACT AND LIFTING THE MATRIX TO A POSITION TO OBTAIN A DESIRED FIBER LENGTH WHILE FEEDING TH PLURALITY OF FIBERS THROUGH THE HOLES OF THE APERTURE PLATE; CASTING A SECOND METAL MATRIX IN THE MOULD CAVITY WHILE THE PLURALITY OF FIBER ARE LOCATED IN THE ARRAY HOLES OF THE APERTURE PLATE AND AFFIXED TO THE PREVIOUS CASTING; INSERTING MOVABLE FIBER GUIDES INTO THE SPACES BETWEEN ADJACENT ROWS OF OPTICAL FIBERS, TWO INTERSECTING SETS OF SAID GUIDES BEING INSERTED BETWEEN FIBER ROWS AT A T POSITION LOCATED BETWEEN SAID CASTINGS: PLACING COMPRESSION DIE JAWS AROUND THE PLURALITY OF FIBERS BETWEEN THE FIBER GUIDES AND THE PREVIOUS CASTING IN CLOSE PROXIMITY TO THE FIBER GUIDES; COMPRESSING THE PLURALITY OF FIBERS IN THE DIE JAWS TO A CLOSE PACKED CONFIGURATION; CUTTING THE PLURALITY OF FIBERS NEAR THE GUIDES; PLACING AND SETTING A BINDER ON THE CLOSE PACKED FIBER CONFIGURATION AND THEN GRINDING AND POLISHING BOTH FIBER END SURFACE ARRAYS.
Claim 2
Independent Claim 223 words
A METHOD OF FABRICATING A FIBER OPTICAL IMAGE TRANSFER AND MAGNIFIER DEVICE COMPRISING: THREADING A PLURALITY OF LIGHT CONDUCTING FIBERS THROUGH AN ORDERLY ARRAY OF HOLES IN AN APERTURE PLATE FORMING THE BOTTOM OF A MOULD CAVITY; CASTING AN INTERISTITIAL MATRIX BY POURING A LIQUID MATRIX MATERIAL INTO SAID CAVITY AND SOLDIFYING THE LIQUID; REMOVING SAID MATRIX FROM THE MOULD WHILE MAINTAINING THE PLURALITY OF ATTACHED FIBERS INTACT AND LIFTING THE MATRIX TO A POSITION TO OBTAIN A DESIRED FIBER LENGTH WHILE FEEDING TH PLURALITY OF FIBERS THROUGH THE HOLES OF THE APERTURE PLATE; CASTING A SECOND METAL MATRIX IN THE MOULD CAVITY WHILE THE PLURALITY OF FIBER ARE LOCATED IN THE ARRAY HOLES OF THE APERTURE PLATE AND AFFIXED TO THE PREVIOUS CASTING; INSERTING MOVABLE FIBER GUIDES INTO THE SPACES BETWEEN ADJACENT ROWS OF OPTICAL FIBERS, TWO INTERSECTING SETS OF SAID GUIDES BEING INSERTED BETWEEN FIBER ROWS AT A T POSITION LOCATED BETWEEN SAID CASTINGS: PLACING COMPRESSION DIE JAWS AROUND THE PLURALITY OF FIBERS BETWEEN THE FIBER GUIDES AND THE PREVIOUS CASTING IN CLOSE PROXIMITY TO THE FIBER GUIDES; COMPRESSING THE PLURALITY OF FIBERS IN THE DIE JAWS TO A CLOSE PACKED CONFIGURATION; CUTTING THE PLURALITY OF FIBERS NEAR THE GUIDES; PLACING AND SETTING A BINDER ON THE CLOSE PACKED FIBER CONFIGURATION AND THEN GRINDING AND POLISHING BOTH FIBER END SURFACE ARRAYS.
Claim 3
Dependent Claim 16 words
The invention as specified in claim 1, wherein the fiber used is made of a polymer.
Claim 4
Dependent Claim 25 words
The invention as specified in claim 1, wherein the fiber used is made of a polymer and the matrix forming liquid is a metal alloy.
Claim 5
Dependent Claim 27 words
The invention as specified in claim 1, wherein the fiber used is made of a polymer and the matrix forming liquid is a metalurgically expanding metal alloy.
Claim 6
Dependent Claim 33 words
The invention as specified in claim 1, wherein the fiber used is made of a polymer and the matrix forming liquid is made of 50.0% Bismuth, 26.7% Lead, 13.3% Tin, and 10.0% cadmium.
Claim 7
Dependent Claim 61 words
The invention as specified in claim 1, wherein a plurality of both fiber end surface arrays are assembled together coherently in close proximity respectively in order to form larger continuous surface arrays by placing the fiber endings in a rectangular array and spacing the fiber endings at the matrix edge rows by one-half of the normal fiber center to center spacing.
Claim 8
Dependent Claim 49 words
The invention as specified in claim 1, wherein the fiber end array containing the close packed fibers is further reduced in size by compressing said array in a die in order to reduce fiber center to center spacing and hence increase the overall magnification of the image magnifier device.
