Title: Improvements in or relating to Methods Of Manufacturing A Picture Screen For A Cathode Ray Tube For Reproducing Colour Pictures
IPC: H01J29/18
Filed: 1966-09-29
Abstract: 1,150,927. Luminescent screens. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 29 Sept., 1966 [2 Oct., 1965], No. 43608/66. Heading H1D. In a method of manufacturing the screen of a colour cathode-ray tube in which the phosphor strips, the intermediate, non-luminescent, opaque strips which separate each phosphor strip, and the indexing strips are provided using a photosensitive binder, the mask which is used to provide the intermediate strips is also used, when partly covered with an additional mask, to provide the phosphor strips and the indexing strips. Preferably also, the hardening radiation after passing through this mask passes through a plane parallel glass plate interposed in a fixed though rotatable manner between the mask and the screen. The mask 2, which comprises a glass plate 5 on which opaque strips 11, 13, 15 &c. have been deposited, the lens system 3, which projects a magnified image of the mask on to the photosensitive layer on screen 1, and the glass plate 4 are fixed with respect to each other and are arranged such that they may be replaced in exactly the same relationship to the screen after each step in the process. The intermediate strips 41-50, e.g. of iron oxide, are first deposited by hardening through mask 2, with the plate 4 parallel to mask 2, selected areas of a photosensitive layer, e.g. polyvinyl alcohol with ammonium dichromate sensitizer, washing away unexposed areas and then depositing the iron oxide from suspension on to the hardened strips. Strips 65-68 of a first phosphor, e.g. the green phosphor, are then deposited by exposing a photosensitive layer containing the phosphor through mask 2 which has two out of each successive three apertures covered by an additional mask 6 and with the glass plate 4 at an angle to the mask 2, as shown in Fig. 2, so that the areas of the photosensitive layer which are hardened lie between the intermediate strips. The remaining sets of phosphor strips, e.g. 75-77 and 101-104 of blue and red, are deposited similarly either by using a different additional mask or by translating the mask 6 with respect to fixed mask 2 so that different apertures in mask 2 are covered. Finally the indexing strips 111-115 are applied in correspondence with alternate intermediate strips over an aluminium layer 105, which covers the intermediate and phosphor strips, by using an additional mask 8 which covers alternate apertures in mask 2 and with the glass plate 4 once again parallel to mask 2 as shown in Fig. 4. The indexing strips may be secondary electron emissive or may emit radiation upon electron excitation. The screen is subsequently heated to bake out the volatile organic compounds.

Filed: 1972-09-25
Abstract: 1402585 Instruction lookahead SANDERS ASSOCIATES Inc 25 Sept 1972 [1 Oct 1971] 44287/72 Heading G4A A digital computer executes instructions, some of which include a test field, using a lookahead facility. A first instruction is executed, its result stored and a second instruction with a test field executed and its result stored. While the second instruction is being executed the test field is combined in a decoder with the first instruction results to give a signal which selectively couples one of a number of instruction address sources to an instruction address bus to fetch the next instruction. Circuitry responsive to the test field and the first instruction results also enables or inhibits storage of instruction execution results. At the start of an execution cycle the results of the previous instruction execution are loaded into an ACU register specified by that instruction. The next instruction is then loaded into an instruction register IR from one of two memories and the incremented instruction address (modified in the previous cycle) is loaded into the instruction address register IAR. The instruction in IR is decoded and while execution is taking place in the ACU the next instruction is addressed. The test code of the current instruction is combined with condition latch outputs to determine whether or not the results of the current instruction are to be loaded into an ALU register at the start of the next execution cycle. A decoder uses the test code to select condition latches to determine if conditional or unconditional program transfer shoud take place by selecting IAR for a step operation or a register (R7) for a jump, call or save operation. The condition latches are set at the start of each execution cycle. The address of a third instruction may be calculated during execution and addressing of the two preceding instructions, the calculated address being loaded into the source address register (R7).

Abstract: 1361808 Synchronized recording of visual images and sound OPTASOUND CORP 27 Sept 1971 [29 Sept 1970 17 Sept 1971] 44817/71 Heading G5R The electric-motor 42 of a cine-camera 10 is started in response to the passage of a first predetermined amount of tape 30 in a tape recorder 20 and is stopped after the passage of a second predetermined amount of film through the camera. As shown, the tape recorder 20 is connected to the cine-camera 10 through two cables 14 and plugs 52, 100 so that closure of the camera start switch 44 starts the recorder motor 70 and not the camera motor 42. The magnetic tape 30 is contained in a cassette and along one edge has perforations spaced equally with the sprocket holes of the cine-film, the recorder 20 having a speed selector allowing the tape to be run at normal cine-film speed (so that corresponding portions of film and tape are of equal lengths and may be aligned, e.g. for editing, by means of the perforations). As each tape perforation passes between a lamp 28 and a photo-transistor or photo-cell 38, circuitry 92, 94, 95 causes a relay 96 to operate and start the camera motor 42. As each film frame is exposed, a pulse generator 55 (which may normally operate a flash unit) sends a pulse to turn off the relay 96 and motor 42 until the next tape perforation passes the lamp 28, so that the film moves in synchronism with the tape 30. On release of the camera start switch 44, the tape is immediately stopped by the action of an electromagnetically-operated brake 108 which grips either the drive belt 74 or the flywheel 76, as described in Specification 1,361,809.

Title: Heat Actuated Control Rod.

Abstract: 1,182,888. Reactor control rods. UNITED STATES ATOMIC ENERGY COMMISSION. 23 Sept., 1968 [1 Nov., 1967], No. 45113/68. Heading G6C. A control rod for a two-region nuclear reactor in which one region is a fast region and the other is a thermal region comprises a container with capillary means on its inner surface end enclosing a mixed condensable vapour of Cd and K. In the embodiment described, one end of the control rod is in the fast inner region of a two-region reactor and the other end is in the thermal blanket region, the fast region of the reactor being operated at the temperature (775  50 C.) at which the two condensable vapours (Cd and K) have equal vapour pressures. An increase in temperature in the fast region will, however, preferentially distil Cd from the fast region to the thermal region and the neutron absorption in this region will increase rapidly, thereby bringing down the neutron flux and temperature of this region. This is due to the fact that Cd has a considerably higher absorption cross-section for thermal neutrons than for fast neutrons. Conversely, a decrease in temperature in the fast region will preferentially distil K into the thermal region (K has about the same low absorption cross-section for fast as for thermal neutrons) and the preferential migration of Cd into the fast region will increase the neutron flux and temperature of the thermal region. The control rod automatically tends to maintain the two-region reactor at about the same neutron flux and temperature. The fast region may be operated at a temperature considerably above 775 C., for example 1500 to 1800 C., if the fast region end of the control rod is suitably insulated by a corrosion-resistant material so that its temperature is in the 775  50 C. range.

Contact material of a first type is applied to a semi-conductor body through an aperture in a first resist layer which is then removed before contact material of another type is applied through a differently-positioned aperture in a second resist layer. As shown, an N-type layer 2 is formed on a P-type germanium slice 1 and is covered with a layer 4 of photoresist material in which an aperture 8 is formed. A deposit 9 of lead-antimony is produced in the aperture 8 by electroplating and a further layer 10 of a mixture of aluminium and gallium is vapour-deposited. The aluminium-gallium mixture is then removed from the photo-resist layer 4 which is itself also removed, leaving the lead-antimony deposit 9 covered with aluminium-gallium. This is heated to alloy it with the germanium, the aluminium on cooling forming a P-type recrystallized layer on the upper surface so that a PNP structure has been obtained. The slice is again coated with photo-resist material in which is formed an aperture differently positioned from the previous aperture 8. A second deposit of leadantimony is produced in this aperture by electroplating as before and is alloyed in, after removal of the photo-resist coating, to form an ohmic connection with the N-type layer 2. By forming a plurality of apertures in each photo-resist layer, a plurality of transistors may be produced from a single germanium slice.
