Title: Photographic apparatus
IPC: G03B15/00
Filed: 1965-04-12
Abstract: 1,108,034. Photographic processing apparatus. EASTMAN KODAK CO. April 12, 1965 [April 13, 1964(2)], No. 15458/65. Heading G2A. Data appearing on the face of a cathode ray tube 12 is directed by a lens unit 13 on to a dichroic mirror 14 which transmits non-actinic light and reflects actinic light through a transparent chamber 6 on to a heat developable photographic web 4 so as to form a latent image thereon, the web being advanced between rolls 3, 7 a frame at a time by a sprocket 5. The latent image is immediately processed by heated liquids or vapours in the chamber 6 which fluids may serve as carriers for processing agents. The visible image is illuminated by non-actinic light from a lamp 16 and projected on to a screen 15, a further filter 21 preventing ambient actinic light from reaching the web which is housed in a light tight housing 10. A second projection system may be provided to illuminate the penultimate processed image in register with a chamber 6' which may be used for fixing, stabilizing or washing. This image is superimposed on the other image on the screen 15, the two images being projected in different colours by means of the actinic light absorbing filters 18, 18', 21, 21'. In another embodiment Fig.2 (not shown) the chamber 6 may be replaced by a transparent block coated with a transparent electrically heated resistance coating.

Title: Improvements in or relating to a method of and apparatus for producing fuel from coking coal or the like
IPC: C10B1/04
Filed: 1931-05-27
Abstract: 386,343. Carbonizing process and apparatus. INTERNATIONAL BITUMENOIL CORPORATION, 75, West Street, New York, U.S.A.- (Assignees of Vandegrift, J. N. and Postel, C. ; 75, West Street, New York, U.S.A.) May 27, 1931, No. 15535. Convention date, May 29, 1930. [Classes 51 (ii) and 55 (i).] Coking coal, or a mixture of coals, is dried at a temperature of about 350‹ F. and charged into tubular vertical retorts in which it is heated quickly to between 1200‹ and 1600‹ F. under superimposed pressure, the temperature being maintained for between 80 and 100 minutes, and the coke, which contains between 6 and 10 per cent volatiles, being discharged into a water-cooled chamber. The charge from a travelling hopper 18 is fed through swinging doors 19 into a set of preheating tubes 23 encased in refractory material 24 mounted on a wheeled carriage 22 which is moved on rails 13 over vertical retorts 33. On movement of a slide 27, the dried charge falls into the retorts, the carriage 22 is returned to under the hopper 18, and a cover 45 is placed over the upper ends of the retorts into which rams 47, mounted on a beam 50, are pressed. The retorts are externally heated by burners 38 extending into passages formed by ribs 35 and flanges 34 on the retorts, which are discharged on opening of the bottom door 60 by operation of the rams, the coke falling into an inclined shaft surrounded by a water jacket 63, and provided with a door 64. The distillates escape from the top of the retorts through the clearance between the rams and the retort walls, and pass through outlet pipes 57 into receivers 56. The vapours from the preheating retorts 23 escape through openings 70 and outlet 72. The hot gases from the retort setting 31 pass through an opening 37, and are reduced in temperature by the admission of air through an inlet 65, before being used to heat the drying tubes 23. The coke from the retorts fractures easily into wedge-shaped pieces having a quick igniting portion of relatively high volatile content near the point of the wedge which was nearest to the centre of the retort, and a slower burning portion extending to the outer surface of the wedge, and adjacent to the more highly heated external surface. The charge in the retort shrinks, and leaves a hollow core which facilitates the evolution of distillates.

Title: Improvements in or relating to automatic control systems
IPC: G01C21/18
Filed: 1943-10-01
Abstract: 611,019. Automatic position control. SMITH & SONS (ENGLAND), Ltd., S., (formerly SMITH & SONS (MOTOR ACCESSORIES), Ltd., S.), and MEREDITH, F. W. Oct. 1, 1943, No. 16160. [Class 38 (iv)] [Also in Group XIX] An automatic system for stabilizing a first body, such as an instrument platform, against the effects of pitching, rolling, yawing, or other movements of a second body on which it is pivotally mounted (e.g. an aircraft), comprises a reversible motor arranged to rotate the first body about its pivotal axis and a device mounted on the second body responsive 'to the rate of turn of that body about the same (or parallel) axis, the device controlling the motor so that it rotates the first body in the opposite direction to the rotation of the second body and at a speed equal to the rate of turn of the latter. A monitor may be carried by the first body to operate a motor, preferably the same motor as used in the stabilizing system, which finally restores the body to its datum position after a stabilizing action. As shown, compass or other instrument platforms 11, 12, pivoted about horizontal axes and arranged, respectively, in the wing and fuselage of an aircraft are stabilized about their axes, despite pitching of the craft, by a rate-of-turn device 13 which controls motors 17 geared to the platform. Device 13 is carried by the body of the aircraft so as to turn therewith, and is of the kind described in Specification 611,005, [Group XXXVIII], thus generating an alternating control voltage of amplitude and phase dependent upon the rate and direction of pitch. Motors 17 drive generators 18 providing for each motor a second control voltage which is dependent upon its speed. The first control voltage, after amplification at 14, is combined with the second control voltage in a resistance network 15, the voltage difference obtained thereby being applied to an amplifier 16, the output of which drives the motor. By adjustment of the resistance arm to which the second control voltage is applied the rotational speed of the platform can be made equal to the rate of pitch. A further voltage is supplied to the resistance network by a monitor 19 if the platform stabilizes at a position other than the datlun position, this voltage then actuating the motor through amplifier 16 in such a direction as to restore the platform to datum position. The monitor may be a device which varies the amplitude of an alternating voltage, obtained through switch 20, in accordance with the angular deviation of the platform from datum position. A further platform, to be stabilized in roll, may be carried by a pitchstabilized platform, stabilization of the former being effected by a motor controlled by a rate-of-roll device mounted on the latter. Specifications 247,633, [Class 97 (iii)], 425,034, [Group XXXVIII], 540,211, (Group XXIX], 576,248, 576,249 and 611,016 also are referred to.
