Title: Photographic method of forming a metal image
IPC: G03C5/40
Filed: 1975-07-29
Abstract: 1486510 Metal images FUJI PHOTO FILM CO Ltd 29 July 1975 [1 Aug 1974] 31788/75 Heading G2X A method of producing an image comprising a metal more electronegative than silver and selected from gold, platinum, palladium, rhodium, iridium and ruthenium comprises forming a silver image by imagewise exposing and developing a material comprising a substrate bearing a photographic silver halide emulsion layer, treating the silver with a compound of the more electronegative material, whereby the silver is partially or wholly replaced by the more electronegative metal, and then heating the material in a gas containing free oxygen to remove the binder of the photographic emulsion layer and any other thermally decomposable matter on the substrate. The substrate can be glass, ceramic, cermet, silica, a silicon single crystal, sapphire, a metal, a metal coated with ceramic, earthenware, silicon, germanium, tellurium, graphite or a synthetic resin film. Suitable binders for the emulsion layer are gelatine, colloidal albumin, casein, a cellulose derivative, a sacchoride derivative, a synthetic hydrophilic colloid, a modified gelatine, a gelatine derivative and synthetic high molecular weight material. Compounds of the more electronegative metals include a salt, a complex, an oxygen acid or its salt, a complex acid or its salt, such as cyano-, thiocyanato, ammine or organic ammine complexes e.g. a chloride; a bromide; a chlorocomplex acid, or a sodium, potassium or ammonium salt of a chlorocomplex acid; a bromocomplex acid or a sodium, potassium or ammonium salt of a bromo complex acid. Before the heating:- some or all of the silver forming the image can be converted to a silver compound which is then removed; or some or all of the silver compound formed can be reduced to elemental silver to form a mixed image of silver and the more electronegative material; or the elemental silver can be replaced by a metal which is more electronegative than silver and which is the same as or different from the more electronegative metal replacing the silver formed by the imagewise exposure and development. One or more conversions can be carried out before the heating step. The method is suitable for preparing photomasks, a printed circuit or circuit elements.

Title: Improved method and apparatus for expanding the volume range during the reproduction of sound films
IPC: G11B7/00
Filed: 1939-12-12
Abstract: 530,673. Sound reproducing. BRITISH ACOUSTIC FILMS, Ltd. Dec. 12, 1939, No. 32021. Convention date, Dec. 16, 1938. [Class 40 (ii)] In a method for providing volume expansion during reproduction of sound films, the average transparency of which varies in accordance with the intensity of the recorded sounds, the scanning light beam is caused to pass at least twice through the sound track before reaching the photo-electric cell in such a way that the beam is modulated once in accordance with the instantaneous value of the recorded sound and again in accordance with the average transparency of the sound track. The invention is described as applied to an anti-ground-noise variable area film. A light beam from a source L, Fig. 1, is focussed by a lens K as a sharp line on the sound track of the film F as it passes round a transparent roller V. At this point the beam is modulated in accordance with the instantaneous value of the recorded sound, after which it passes across the roller to the opposite side E, diverging slightly so that it extends over several wavelengths of recorded sound and over the whole width of the track. The light reaching E is thus further controlled in accordance with the average width of the track before finally reaching the photo-electric cell C and since amplitude control is effected on both passages through the film, a change of output varies as the square of a corresponding change of recorded amplitude. In another embodiment, a cylindrical reflector is situated inside the drum so as to reflect the scanning beam out of the drum at points on either side of its point of entry, Fig. 3 (not shown). In a third embodiment, control in accordance with the average transparency is effected first by means of a band of light produced by a cylindrical lens after which a mirror within the drum reflects the beam to form a thin line for sound modulation, Fig. 5 (not shown).

Abstract: 998,865. Core-making machines. PETTIBONE MULLIKEN CORPORATION. Aug. 27, 1962 [Sept. 14, 1961], No. 32829/62. Heading B3F. A shell core-making machine comprises a framework 10, a lift table 22, a lower core-box section 24, an upper core-box section 20, a sand magazine 18 and a blow valve 26, all arranged in a vertical series, a support on the framework for the upper core-box section which is movable between the support and the magazine, the lower core-box section 24 being supported on the table 22 which is movable vertically first to bring the lower core-box section 24 into contact with the upper core-box section 20, which is then lifted from its support into contact with the magazine, which is then lifted into contact with the blow valve. The magazine 18 is carried by a carriage 90 actuated by a cylinder 121 so as to be movable between a position beneath a sand hopper 16, Fig. 7, and a position over the core box, Fig. 5. The carriage also supports a device 30 comprising gas burners 31 and coreejection pins 36, the burners and ejectors being vertically movable by a pneumatic piston 162. The device 30 is positioned over the core box when the magazine is positioned beneath the hopper, Fig. 7. The lower core box section 24 also includes gas burners 32 and core-ejection pins 42, on which the cores remain supported, Fig. 12, when the table 22 is in its lowermost position after completion of a moulding cycle. The cores may be picked from said pins by a core-unloading apparatus 14 as described and claimed in Specification 947,451 which is referred to. In operation, and with the filled magazine in line with the blow head and core box, upward movement of the table 22 by means of the cylinder 212 clamps the core-box sections, magazine and blow head together for filling of the core-box cavities by pressure air supplied through the blow valve 26, Fig. 6. The table is then lowered slightly to relieve the clamping pressure and allow the carriage 90 to be retracted to bring the upper burner and stripper assembly over the core box, the burners 31 and lower burners 32 then curing the core. Before curing is complete the piston 162 is moved downwardly to cause the stripper pins 36 to enter the blow holes 244 in the upper corebox section to a limited extent stops 152, 153, causing further movement of the piston to lift the carriage against stops 67, Fig. 6. After curing of the core is complete, the downward movement of the table is continued until the top core-box section seats on stops 80, continued downward movement of the table then allowing the ejector pins 36, still under the influence of the piston 162 to strip the cores from the upper core-box section, Fig. 9. Continued movement of the table then brings the lower mould box section ejector plate 38 against stops 140 and the cores are stripped from the lower core-box section and left supported by the ejector pins 42.

Abstract: 775,984. Analogue electric computers. AIR TRAINERS, Ltd. Nov. 26, 1954 [Nov. 26, 1953; March 3, 1954], Nos. 32854/53 and 6244/54. Class 37.  The rolling, pitching and yawing rates W1, W2, W3 respectively of a moving aircraft as determined by known means are combined in a computer to determine the angular displacement of each of the aircraft's axes relative to the vertical, using the relationships : &c., where C1, C2, C3 are the cosines of the angles between the axes and the vertical. As shown (Fig. 1), input voltages representing the angular velocities W1 &c. are fed into potentiometers 7 whose sliders 8 are positioned in accordance with the cosines C1 &c. to give voltages representing W1, C2, &c., which are added algebraically in a summing amplifier 6 controlling a servomotor 5 which drives a feedback generator 9 and positions its potentiometer group in accordance with the time integral of the input to amplifier 6. To check the accuracy of the apparatus, voltages representing C1<SP>2</SP> &c. are obtained by three sets of double potentiometers (Fig. 2) and the resultants added. If the settings are correct the result of this addition is a voltage equal to the input voltage, i.e. C1<SP>2</SP> + C22 + C32 = 1; any error voltage is fed into the input side of any amplifier 6 of Fig. 1. The servomotors 5 may be used to obtain the cosine component values of other angles or quantities, e.g. weight, or the angular position of the aircraft axes relative to any fixed threedimensional axes. It may be applied to the determination of the angular relationships be. tween a guided missile and a moving target.
