Title: Method of making colour screen of cathode ray tubes
IPC: H01J9/227
Filed: 1965-02-12
Abstract: 1,085,470. Colour television tubes. SONY CORPORATION. Feb. 12, 1965 [Feb. 13, 1964], No. 6182/65. Heading H1D. In a method of making a multi-colour display screen for a colour television tube, e.g. of the colour-switching' grid type or the shadowmask type, an electron sensitive and light opaque layer on a support is exposed to an electron beam to varying degrees in different areas and successively washed in trichloroethylene, for example; coated with a phosphor slurry containing a substance capable of being made opaque by exposure to light or by a chemical treatment and a substance which is photo-sensitive; exposed to ultra-violet light through the support to fix the slurry; treated to render the slurry opaque; and washed to remove unexposed slurry. The first trichloroethylene washing step removes the more heavily exposed red areas, say, of the electronsensitive layer, and the process is then repeated for the blue and green areas, earlier areas acting as optical masks for later areas. The green phosphor slurry, however, need not contain a substance capable of being made opaque. Finally, the opaqueness of the opaque substances formed during the above processes may be dispersed by a baking process. In a switching-grid type tube the phosphor areas are selected and exposed to the electron beam by applying voltages to the grid wires.

IPC: G01P1/10
Filed: 1953-03-10
Abstract: 744,678. Automatic voltage control systems. ELEKTROMEKANO AKTIESELSKAB. March 8, 1954 [March 10, 1953], No. 6610/53. Class 38 (4). [Also in Group XL (c)] In a self-excited generator having voltage regulator means controlled by a voltage-responsive relay, a lamp supplied with a pulsating voltage corresponding to oscillations of the relay armature acts as a speed indicator. In the embodiment described, the shaft G20 of a generator is rotated manually by the handle G38. The generator comprises a low-tension armature G16, a high-tension armature G18 and a field winding G22, energized from the low-tension output through a control resistance G24 shunted by the contacts G26 of a relay G28. At a pre. determined speed relay G28, energized by the low-tension voltage operates to open contacts G26 and remove the short-circuit on resistance G24, to lower the voltage and thereby deenergize relay G26. Thereupon the voltage is raised again and the cycle repeats again. A lamp indicator G40 connected across resistance G24 therefore flashes on and off continuously and visibly when the speed is in the desired range, whereas outside this range it is either unenergized or appears to be continuously energized.

Abstract: 951,705. Automatic gramophones; improper use,preventing. UNITED MUSIC CORPORATION. Feb. 21, 1962, No. 6775/62. Heading G5R. A cut-off device in an automatic gramophone comprises a trigger tripped by the tone arm when reaching a cut-off position, said trigger being provided with a trip abutment in the path of a trip member secured to the tone arm, and with a holding surface for engagement with a yieldable cutoff member. As applied to a juke-box in which records are brought into engagement with the stylus 4 by the elevation of the turntable under the influence of an arm 32 and motor driven linkage 35, 36, the said yieldable member is the blade 18 of a switch controlling the automatic cycle at the end of a record. During playing of a record, the mechanism is in the condition shown in Fig. 2. At the end of the record, a tripping arm 15 on the tone arm 3 moves a trigger 22, pivoted at 23, so that the switch blade 18 slips from a stepped member 26 thereon and closes the switch 17, 18 to start the automatic cycle. Through the medium of a link 38, the subsequent lowering of the turntable moves clockwise a lever 6, pivoted at 7, whereby the tone arm is swung outwardly and the mechanism takes up the condition shown in Fig. 5 in which the switch 17, 18 is open again ready for a further record playing. The apparatus is provided with inertia switches which in the event of the machine being jolted, close and cause an electromagnet 29 to move the trigger 22 into the tripped position, as shown in Fig. 4.

Abstract: 1,131,605. Forced flow steam generators. SULZER BROS. Ltd. 16 Feb., 1966 [16 Feb., 1965], No. 6799/66. Heading F4A. [Also in Division G6] A once through forced flow steam generator, heated by coolant gas from a nuclear reactor comprises a easing 18, containing an open ended bell-shaped shell 15 and a central longitudinal duct 16. Gas from the reactor enters at spigot 31 and flows downwardly in the annular space between the shell 15 and the duct 16 over spaced banks of spiral superheating, reheating and combined evaporator pre-heating tubes 12, 13, 14 respectively, to a bottom reversal chamber defined by members 50 and 43. The gas then enters the circulating blower 33 through annular entry orifice 32 to pass to distributor element 35. From here the gas passes upwardly in two streams to the exit spigot 41, both through the central duct 16 and through the radial arms 37 to the annular space 19 between the casing 18 and the shell 15. The radial arms 37, 38 and 39 serve to support the evaporators, reheater and superheater tubes 14, 13 and 12 respectively. Gas may also flow from the central duct 16 to the annular space 19 through the arms 38, 39. Feed water from a power plant is supplied through tubes 44, the steam produced in the evaporator section 14 flowing through tubes 51 to the superheating section 12 whence the steam leaves through tubes 52. Steam to be reheated in section 13 is supplied through tubes 45 and the reheated steam withdrawn through tubes 53. The high temperature withdrawal tubes 52 and 53 are separated from the lower temperature supply tubes 44, 45 by the member 50 and a jacket 48. On assembly the arms 37-39 are first cantilevered from duct 16 and the tube bundles 12-14 assembled on the arms and interconnected. The jacket 48 is fitted and the shell 15 is pushed over the bundles 12-14 and connected to the arms 37-39 and to upper closure member 30 to which duct 16 is attached. The shell 15 is then connected to an intermediate ring 42 and a bottom closure member 43 and the casing 18 pushed over the shell 15 to connect to the ring 42 and to an upper outer closure member 40. The tubes 44, 45, 52, and 53, member 50 and the blower 33 are then assembled in the gas reversal chamber, and the whole structure mounted in bearing ring 46. In a modification (Fig. 1) the heat exchange casing is directly connected to the outer casing surrounding a nuclear reactor (see Divisions G4-G6).

Abstract: 216,245. Meadows, S. C. March 10, 1923. Compositions containing bituminous materials and india-rubber for making and waterproofing roads are prepared by incorporating rubber latex with a tarry or bituminous base. Vulcanizing- agents may be added and the mixture heated if necessary to vulcanize the rubber. A composition for spreading on roads as a waterproofing- agent is made-by adding 1¢ parts of latex (containing 50 per cent of rubber) to 98¢ parts of a tar base composed of 74¢ parts of coal tar, 10 parts of anthracene oil, 10 parts of petroleum pitch, and 4 parts of viscous petroleum residues. A composition for mixing with a filler such as sand, ground limestone, asbestos powder, and sawdust consists of tar base as above, containing 2¢-5 per cent of latex with the addition of sulphur, and is vulcanized by heating to 350‹ F. Compositions containing more than 5 per cent of latex are relatively infusible and mav be cast into blocks; those containing less than 5 per cent can be melted in the ordinary tar boilers and used in the liquid state.
