Title: Image display employing filter coated phosphor particles
IPC: H01J29/02
Filed: 1974-08-22
Abstract: 1479038 Luminescent screens R C A CORPORATION 22 Aug 1974 [4 Sept 1973] 36947/74 Heading H1D [Also in Division C4] An image display device comprises a luminescent viewing screen comprising phosphor particles with colour filter particles adhered thereto and partially covering the surfaces of the phosphor particles, the phosphor particles being emissive of light in a particular portion of the visible spectrum and the filter particles being preferentially transmissive of light in that spectrum portion. The device may be a colour shadow mask or monochrome C.R.T. or photoluminescent or electroluminescent screen. The arrangement enables transmission and variations of transmission, absorption and reflection of light of different portions of the visible spectrum to optimize brightness and contrast. The red emitting target elements R1 may be principally Eu activated yttrium oxysulfide with red transmitting filter particles 57 of cobalt aluminate of 0À1 to 0À5 Á average size, blue emitting elements B of Ag activated ZnS with blue filter particles of a cobalt aluminate of 0À1 to 0À5 Á average size, and uncoated green emitting elements of Cu activated ZnCdS all backed by reflecting layer 33. The elements may be circular in hexagonal interfaced array. Elements R1 are loosely packed 1 to 4 particles thick and emit red light with possibly some other spectral components some of which are absorbed by particles 51 which also absorb light from ambient sources, the blue elements having analogous characteristics. Other red phosphors may be Mn : Zinc orthosphosphate; Ag : ZnCdS; Eu : yttrium vanadate and Eu : yttrium oxide. Red filters may also be ruby, red tinted silicate glasses and red ceramic pigments. Blue phosphors may be Ti : calciummagnesium silicate and Tb : yttrium oxysulfide, and blue filters may be ultramarine blue tinted silicate glasses and blue ceramic pigments. Green phosphors may be willemite, Mn : zinc aluminate and Ag : ZnCdS and green filter material may be Cr 2 O 3 , mixtures of yellow cadmium sulfoselenide and blue green cobalt aluminates, green tinted silicate glasses and green ceramic pigments. In Fig. 5, additional R3 and B3 elements are free of filter particles since they may here reduce brightness and are unlikely to absorb ambient light. In Fig. 2, G1 elements may include filter particle coatings and may be of the double layer form. Coating procedure is detailed using gelatine absorptive films and filter particle suspensions. Phosphor and filter particle sizes are exemplified. Reference is made to U.S.A. Specification 3,275,466.

Abstract: 810,363. Continuous-casting processes. MARVALAUD Inc. Dec. 7, 1956 [Feb. 16, 1956], No. 37438/56. Class 83 (1). A process for collecting continuous metal filaments formed by chilling a high-speed stream of molten metal projected under pressure, consists in moving the filament 14 by a gas-stream to a collecting-device 16, and collecting the filament concurrently with its formation. The molten metal stream 5 impinges on a rotating chill-block 7, and is projected as a solid filament into a guiding tube 16, down which it is blown by a gas-jet 21. The filament passes down into a tube 22 which is reciprocated to distribute the filament in a coil on the walls of a rotating container 26. Several containers may be mounted on a table which is indexed as each container is filled. In a modification, the filament is formed by projecting the metal into a gas-jet A, Fig. 2. The filament is then sucked into a tube 20 and directed by an oscillating tube 22 on to an intermittently-advancing belt 33. It is picked up from the belt by rollers 34 and guided on to a bobbin 36.

Abstract: 1,013,277. Endless conveyers. N. V. MACHINEFABRIEK V. H. JOHS ABERSON. Oct. 4, 1962 [Sept. 12, 1962], No. 37539/62. Heading B8A. Sets of seven spaced green bricks 2 dried on pallets 1 are transferrd, three sets at a time, at a station 9, from their pallets to a track 10 by pushers 13 on an endless conveyer 12. The bricks are initially on their broad faces and are pushed over a tilting edge 14 thereby being turned on to their narrow faces on a supporting conveyer 15. The conveying run of the conveyer 15 is at rest during this transfer but the conveyer 15 as a whole is supported on a carriage 16 running in a framework 18 on rollers 17 moved in synchronism with the conveyer 12 through a cam 20 actuating a rack- and-pinion drive to the carriage 16 so that the bricks are deposited adjoining each other on the conveyer 15. When a complete batch of three sets of bricks has been transferred to the conveyer 15 the drive to its conveying run is started by operation of a switch by the carriage 16 reaching an extreme of its run. The bricks 2 are fed to an intermediate conveyer 33 which is at this stage driven at the same speed as the conveyer 15 through a dog clutch 35. When this transfer is complete the carriage 16 under the action of the cam 20 returns to its other extreme to collect a further batch of bricks 2, thus disengaging the dog clutch 35. The intermediate conveyer 33 is now driven at the same speed (slower than that of the conveyer 15) as a terminal conveyer 34 through a chain 37 and a sprocket 38 which has a free-wheel clutch 39 permitting the drive from the conveyer 15 to override the drive from the conveyer 34 when the dog clutch 35 is engaged. The bricks are finally transferred to the terminal conveyer 34 whence they are removed by hand for firing.
