Title: Improvements in cinematograph films and a method of making the same
IPC: G02B27/14
Filed: 1922-05-02
Abstract: 194,971. Comstock, D. F., and Technicolor Motion Picture Corporation. May 2, 1922. Colour kinematography; kinematograph apparatus. - In the production of colour-record kinematograph films having simultaneously-exposed complemental images in separate areas on the same side of the film, the members of each pair of images are relatively reversed and symmetrically disposed with reference to a line between them. In projection the film is positioned by means of pins which enter sprocket holes in definite relation with the line of symmetry of the images. The reversed images, shown in Fig. 3, are produced by means of a compound prism P<2>, P<3> between the lens L and the film M, N, whereby part of the beam entering the prism is reflected at the surface x<11> and part transmitted, both reflected and transmitted portions being subsequently reflected at the surfaces x<2>, y<2> respectively, to form relatively inverted images M, N on the film. Alternatively. the prism may be situated in front of two lenses. The line of symmetry z passes between the two images. Four images, disposed as shown in Fig. 6, are produced by the addition of a second compound prism B, Fig. 4. In the production of three complemental images an additional compound prism is placed between the lens L and the prism P<2> having a reflecting surface, reflecting one-third of the light in a manner similar to that of the prism shown in Fig. 1, the images in this arrangement being such that one only is inverted. In every case the sprocket holes are arranged so that one comes on or near to the line of symmetry of the images. In projecting the images, a prism set 3 is mounted in front of the film gate, which is fitted with reciprocating registering pins 8 arranged to enter the selected sprocket holes r, and actuated by a cam plate and lever 12 operated from the driving mechanism. One of the pins 8 is of the same size as the sprocket hole and the other of the same length, but of less width than the hole, so that variations in the film due to expansion or contraction are allowed for. Specification 131,422 is referred to.

Abstract: 1,065,088. Televizing from moving vehicles; cathode-ray tube circuits. NORD-AVIATION SOCIETE NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. March 24, 1964 [March 28, 1963], No. 12481/64. Headings H4F and H4T. In a television camera mounted in an aircraft with its optical axis aligned with the axis of movement the effects of roll, pitch and yaw movements are nullified by rotating and moving the scanning raster so that the scanned area on the target remains correctly orientated and aligned with respect to the optical image viewed by the camera. In Fig. 3 the pitch and yaw rotations # and # are detected by a gyroscope system 10, translated into voltages by potentiometers 14 and 15 and applied to the vertical and horizontal deflection coils 17 and 16 so as to cause the scanned raster to follow the, movements of the image on the camera target. In Fig. 5 the effect of roll rotation # is allowed for by altering the line and frame scanning deflections Y and Z in accordance with the equations Y=V l  cos # - V i  sin # and Z = V i  cos # + V l  sin #, where V l  is the normal line scan deflection and V i  is the normal frame scan deflection. The multiplying factors are introduced by a pair of Hall cell multipliers 24 which are supplied with the line and frame voltages L and I and are controlled by a magnet 23 which is stabilized vertically by a gyroscope system 20. The two components of voltages Z and Y are added in adders 25 and 28 and applied via amplifiers 26 and 29 to the camera deflection coils 27, 30. Fig. 6 shows an alternative arranged where the scanning raster is of spiral form produced by a sinewave 40 amplitude modulated by a sawtooth wave 41 in a modulator circuit 42. 90 degreesphase-displaced signals are derived from a device 47 and applied to the deflection coils 44 and 45 via amplifiers 46. In accordance with invention the roll angle is detected by gyroscope 43 and is employed to rotate the phase of the signals produced by device 47.

Patent GB-127590-A (GB)
IPC: C10B5/02
Abstract: 127,590. Soc. Franco-Belge de Fours Ó Coke. May 29, 1918, [Convention date]. Coke ovens.-In a vertical-flued coke oven adapted for heating either by rich or poor gas and having four regenerator tunnels extending the length of the bench beneath the ovens, two of the tunnels are divided into compartments corresponding in number with the ovens, so that when desired poor gas can be heated in some of the compartments for combustion with air from the undivided regenerators, while air is being heated in other compartments for combustion with unheated rich gas. When rich gas is being used for firing all the heating-walls, all the regenerators are utilised for air, and when poor gas is employed throughout the bench, the undivided tunnels are used for air, and the divided ones for the gas. In the construction shown, the outer regenerators b, b<1> are compartmented, while the inner ones a, a<1> have partitions 12, which do not extend to the roof. The cross-sectional area of the flues k between the compartments of the regenerators b, b<1> and the main flues d, d<1>, and of the ports f between the regenerators a, a<1> and the flues c, c<1>, varies with the distance from the chimney stack. The regenerators a, a<1> and b, b<1> are connected with alternate half sole flues 7, 6 respectively, and each of these delivers to the heating-walls on both sides of it. The supply of poor gas to the regenerators b, b<1> is controlled by valves h, h<1>, and of rich gas to the chambers 4. 4<1> at the base of the heating-flues by valves m, m<1>. Reversal is effected by a single valve controlling the outlet to the chimney, valves or dampers being also fitted in the channels leading from each regenerator to the reversing-valve. If desired, rich and poor gas can be used simultaneously for firing a heating-wall.

Abstract: 376,873. Feedwater regulators. WEIR, Ltd., G. & J., Holm Foundry, Cathcart, and HILLIER, H., 27, Fotheringay Road, both in Glasgow. May 5, 1931, No. 13224. [Class 135.] A feedwater regulator for steam generators of the kind actuated by feedwater pressure acting on a piston under the control of a float actuated auxiliary valve has a second auxiliary valve secured to the main actuating piston arranged so that the main valve follows the movement of the first auxiliary valve. In the form shown in the Figure the actuating piston o which is arranged below the valve n is fitted with a needle valve t cooperating with a seat s adjustably locked to the casing p by a nut w. The position of the needle valve may be adjusted by washers z. The auxiliary valve c is also formed as a needle co-operating with an adjustable seat u and is actuated by a pivoted float a arranged in a casing f connected to the generator through conduits g, h. As the water level falls the valve c opens to admit feedwater from a pipe k to a pipe l connected to the chamber m beneath the piston. Feedwater also enters the chamber through the clearance around the piston o. Water passes away from the chamber m through the conduit s<1> under the control of the needle valve t which is moved to increase the discharge until a position of balance is reached. The valve c may be arranged to close as the level falls in which case the needle valve t is arranged to close as the main valve opens. The discharge pipe may be replaced by a passage in the piston. The actuating piston may be arranged above the piston so that an increased pressure in the actuating chamber closes the main valve.

[Classes 83 (ii) and 83 (iv)] Tapered tubes, particularly those for the spar roots for helicopter blades described in Specification 635,082, [Group XXXIII], are made from tubular stock material, preferably chrome-molybdenum steel. The tube is first swaged down at one end to a smaller diameter in one or more steps, the thickness being correspondingly increased. Machining then follows to provide a smooth inside and outside finish with a shoulder 3 adjacent the larger end. A cast iron mandrel 7 provided with a pilot but otherwise conforming to the required internal shape, is now forced into the tube as far as possible, the pilot protruding at the small end and the assembly is run through a roll pass 13 progressively to alter the shape of the tube to fit the mandrel that can now be inserted further with the aid of a press 14 that engages the shoulder 3 and has a hand screw 16 engaging the end of the mandrel. Shape rolling is then completed and the blank is cut off to length. The attachment fitting 19 of the same material as the tube is copper brazed to the cylindrical end of the tube which is then heated to about 1650‹ F. and quenched and tempered at 950‹ F. Finally, the leading end of the fitting is tapered away to an edge and the tube is similarly tapered at its rear end so that abrupt changes of section are avoided. The spar is now ready for insertion in the blade.
