Les Flory Collection

The Collection

The Les Flory Collection contains photos, documents, and artifacts passed down from Grandpa.  Most pertained to his work, but some he collected for their novelty or interest.
I have collected a few items that relate to Grandpa's work, such as a production iconoscope tube model 1846, and three examples of the Navy infrared signalling telescope that used the 1P25 image tube that Grandpa worked on. 

1930 Iconoscope Mosaic, probably built by G. Ogloblinsky, described in Iams


Oblique view of mosaic, taken by my father, Robert E. Flory. 

1932 Iconoscope tube, built by Les Flory


1932 Iconoscope tube, built by Les Flory.  The experimental tubes are numbered, and this is number 100.  I have not found reference to this particular tube in Iams.  Grandpa said that this one worked.  Note the flat optical surface in front of the mosaic, differing from the spherical tubes.

1930 Iconoscope Mosaic.  This is described in Iams, "A Review of Iconoscope Development..."  See Documents section.  This hand-built mosaic consisted of a honeycomb structure, into which rivets with glass tubing surrounding them were inserted into each cell.  A sheet of mica under the heads of the rivets insulated them from the honeycomb.  The honeycomb served as the signal plate.  The rivets were silver(plated if not solid) sensitized with Cesium.  Each rivet generated one picture element, so it was realized that to get to the number required for a high-definition picture, this technique would not be practical, even though it did work.

1946 Reading Aid for the Blind

1955 RCA  Industrial Vidicon Camera prototype believed to be the first all-transistor TV camera.

1953 Lab Demo Transistor Radio

1P25A Infrared Image Tube

British Military Infrared Image Tube

Graphecon Storage Tube.  This tube was a type of analog memory.  It was used to store radar images for signal processing purposes. 

LMS15 Miniature Image Orthicon

Lab Prototype 1/2" Vidicon

Miniature Mock-up Iconoscope

6198 1" Vidicon

SX-100 and SX-160 Developmental Transistors

"A Review of Iconoscope Development Between April 1930 and October 1933" by Harley Iams.  Zworykin copy.
"A Six-Megacycle Compatible High-Definition Color Television System", given by RCA before the FCC September 26, 1949.  This paper describes 2 and 3-kinescope color TV systems, one of which was a converter used in conjunction with a 630TS receiver.
"Questions and Answers about Color Television", by CBS, December 1950.  This paper is apparently a response to the FCC's "Statement concerning Color Television", dated November 16, 1950.
Reprint of "Television With Cathode-Ray Tubes", by V. K. Zworykin from the Journal of the Institution of Electrical Engineers, Vol. 73, No. 442, October, 1933.  Signed "With Author's Compliments, V. Zworykin, Nov. 7, 1933".  The paper acknowledges Gregory Ogloblinski, Sanford  Essig, Harley Iams, Art Vance, and Leslie Flory who, "carried out much of the experimental work connected with the development described in the paper, and whose ability was the major factor in the successful solution of the many problems which arose in the course of the investigation."
A reprint of a German version of the above paper, "Fernsehen mit Kathodenstrahlrohren", which was published in Jahrbuch der drahtlosen Telegraphie und Telephonie 43, 109-121, 1934, also signed by Zworykin.
Reprint of "Theory and Performance of the Iconoscope" by V.K. Zworykin, G. A. Morton, and L. E. Flory, from The Journal of the Institution of Electrical Engineers, Vol. 82, No. 493, January 1938.  Also a letter and certificate awarding the Overseas Premium for the 1937-38 session of the Institution.
