Title: Manufacture of luminescent screen structures
IPC: H01J9/227
Filed: 1971-05-05
Abstract: 1342636 Electroless plating R C A CORPORATION 5 May 1971 [5 May 1970] 13344/71 Heading C7F [Also in Division H1] A method of producing a luminescent screen structure for an image reproducer (e.g. a c.r.t.) comprising light emitting and light absorbing areas on a support surface 23, comprises coating the support surface with a pattern of deposits comprising film-forming binder material and phosphor particle electrolessly plating only the areas between the deposits with at least one of Ni, Co and Cu, and optionally also including Fe, Mn or W, and converting the plated metal to an adherent dark coloured and light absorbing compound material. Surface 23 may be coated with an initiator by cleaning and washing with a 10% aqueous solution of fluoroboric acid to leach and render hydrophilic, rinsed with an aqueous acidic stannous chloride solution whereby stannousions are absorbed, rinsed with Pd salt solution, Pd ions replacing stannous ions producing discontinuous monolayer 25. Green, blue, red phosphors 27, 29, 31 are photographically offset or screen printed, the phosphor being mixed with the binder or applied after the binder is printed. Plating may use Co So 4  7H 2  O, sodium pyrophosphate and conc. ammonium hydroxide, pH being 10 to 10-5 and 90 to 100F temperature producing 0.005mn thickness, followed by aluminizing and baking at 440C in air to oxidize the Co to a black material of one or more oxides and removing organic material. The conversion to a dark coloured material may be by oxidizing or sulfurizing or otherwise converting Ni and Co from black oxides and sulfides and conversion may be by baking in a gas ambient or by a reaction in a liquid medium. In plating, both temperatures of 90 to 100F reduce non-uniformities, a thin layer of an additional promoter, e.g. heat treated tin oxide, leached or hydrated suface, beneath the initiation reduces peeling, phosphor dot porosity may be reduced by baking at 150C or by incorporating an organic filler (e.g. an acrylate copolymer) to promote the hydrophobic character. The film forming binder used with the phosphor reduces Co metal ion poisoning. Reference is made to shadow mask colour TV tube with a light absorbing screen matrix.

Title: Radiant energy detection system
IPC: G01S3/781
Filed: 1976-04-05
Abstract: 1512754 Removing ambient effects in photoelectric systems THOMSON-CSF 5 April 1976 [7 April 1975] 13738/76 Heading G1A Radiation is filtered and modulated in such a way as to separate wanted and unwanted components. In Fig.1 the radiation is incident on an optical system 1 which splits it into two beams as described later; these beams are incident on a grid 3 which is moved to and fro to modulate the beams received by a photo-detector 2. The beam-splitter of optics 1 splits the incoming wanted radiation into a strong beam I, and a weak one I 2 , as in Fig.2 (not shown). The separation of these beams corresponds to the pitch of the grid, so that as the grid moves there is a sinusoidal variation in the wanted radiation incident on the detector. However, the beam-splitter splits the unwanted radiation into two similarly spaced beams 13, I 4 , Fig.3 (not shown), these beams having equal intensity. When the grid moves there is effectively no change in the unwanted radiation incident on the detector. Thus the detector signal can be amplified at 6 and demodulated at 7 to give an output representing only the wanted radiation. Beam-splitter. It is necessary to know the spectrum of the wanted and unwanted radiation. In Fig.6 the wanted radiation is SU and the unwanted is broadband SP. Two filters are provided, having passbands at C 1  and C 2  as shown. A suitable splitter has an objective 10, Fig.7, preceded by filters 11a, 11b which correspond to C 2  and C 1 ; beam displacement is produced by a prism 15. The wanted radiation passes through filter 11b but is substantially attenuated by 1a; the result is beams I 1  and I 2  of Fig.2. The unwanted radiation passes through both filters, giving beams I 3 , I 4  of Fig.3; balance is achieved between I 3  and I 4  by choice of the passband of 11a and 11b, and by providing a balancing filter 16, 17. In another splitter two objectives with separate filters are used, the beams being directed to the detector by a semitransparent mirror, Figs.10, 11 (not shown). Modification: the two beams may be detected separately by detectors (2a), (2b), Fig.12 (not shown), having respective grids (3a), (3b) which are 180 degrees out of phase with one another. Grids: the size of the grid lines, and their spacing, depends on the size of the images produced by the objective and on the separation produced by the splitter. The grids may be moved to and fro, or may be formed by radial lines on a rotating disc. The grid lines need not be straight, e.g. a chevron pattern can be used to distinguish a circular wanted image from an elongated unwanted one, Fig.16 (not shown).
