Filed: 1946-11-01
Abstract: 633,079. Recording apparatus. SCOPHONY, Ltd., and ADAMS, A. E. Nov. 1, 1946, No. 32546. [Class 106 (iv)] [Also in Group XXXVI] To identify intersecting traces, as for example in Fig. 2, the traces are each caused to undergo a momentary change of character such as brightening in a definite time sequence as indicated by dots 23, and the dots on each trace are then located by means of cursor lines 24 and 25. Referring to Fig. 1, mirrors 13 of oscillographs, all of which produce traces in a film passing over a roller 15, are each illuminated by a lamp 10 in series with a resistor 12. A rotating commutator switch short circuits the resistor of each lamp in turn, causing a momentary brightening of the trace. The first and last brushes 20a and 20b of the switch are widely spaced to determine the commencement of each trace. The rotating switch may be replaced by a rotating light shutter. It is stated that the invention is applicable to cathode-ray oscillographs in which a brightening pulse synchronized with the time base may be fed to the control grid or to the focusing electrodes.

Title: Display surface for color television tubes
IPC: H01J19/00
Filed: 1952-12-23
Abstract: 721,523. Colour television tubes. CHROMATIC TELEVISION LABORATORIES, Inc. Dec. 23, 1952 [Jan. 8, 1952]. No. 32576/52. Class 39 (1). A luminescent screen for a colour television tube comprises a supporting base, a number of spaced phosphor strips of substantially uniform width deposited on the base and extending across the base in one dimension, the strips being adapted to luminesce in one primary colour, and intermediate strips substantially filling the spaces between the first strips, the intermediate strips being comprised of alternate quadrilateral areas of phosphors luminescent in the other two primary colours. In one embodiment, Fig. 3, the continuous strips G are of green fluorescent material and the other strips are divided into blue fluorescent areas B and red fluorescent areas R. In part of the screen there may be provided a grid comprising four sets of conductors 27, 27<SP>1</SP>, 35, 35<SP>1</SP>, Fig. 2, the four sets being insulated from each other and serving to focus the beam and to deflect it to the required fluorescent area. The fluorescent material is preferably coated with a metallic layer which forms a lens in combination with the grid wires. Preferably the potential between the grid and the screen is three times that between the cathode and the grid; since the horizontal wires 35 must be spaced from the vertical wires 27 their potentials relative to the screen should not be equal but should be proportional to their distances from'the screen. The electron beam will normally impinge on the points where the phosphors meet; sine waves 90 degrees out of phase applied to the grid wires cause the spot to rotate about these points; since the beam will then cover twice as much of the green phosphor as of the other two phosphors this would produce an unsaturated green colour but by applying a fixed bias between wires 27 and 27' a white colour may be produced. By keying the beam in synchronism with the spinning of the focal spot any colour may be produced. In another embodiment, Fig. 5, the continuous strips B are of blue phosphor and the grid wires 65, 67 lie over the boundaries between the phosphors; colour selection is obtained by using a tube with three electron guns, Fig. 4 (not shown).
