Title: Improvements in electro optical systems for the reproduction of multi-coloured originals
IPC: H04N1/60
Filed: 1942-11-02
Abstract: 561,844. Copying in colour by scanning. KODAK, Ltd. Nov. 2, 1942, No. 15372. Convention date, Nov. 1, 1941. Drawings to Specification. [Class 40 (iii)] In the electro-optical reproduction of multicoloured originals, colour correction is obtained by producing in separate channels separate electric currents corresponding respectively to a colour to be corrected and to the correcting colour, so amplifying the respective currents that the current intensity of the correcting colour is less than the current intensity of the colour to be corrected, feeding one of these currents to one of the ribbons of a ribbon-type light-valve having two substantially parallel ribbons, and feeding the other current to the other ribbon. Specifications 488,836, 538,012, 538,013, 552,367, and 561,845 ; and U.S.A. Specifications 2,176,518 and 2,221,037 are referred to.

Abstract: 420,439. Radiants for gas fires. NICHOLS, F. G., 444, Woolwich Road, Charlton, London. May 31, 1933, No. 15718. [Class 126] The radiants A, B of a gas fire have different openwork designs on their front faces C such that when they are assembled a substanti ally continuous pictor ial representation is produced. The sides o: each radiant are at right-angles to the from face, and are providec with cut-out portions E in conformity with the design on the front face to prevent the appear ance of any junction line.

The representation on each radiant may be complete in itself. The radiants may be inclined, or curved longitudinally or laterally, and may be assembled one above the other instead of side by side. The front and back faces of the radiants may have studs or be roughened.

Abstract: 844,396. Follow-up devices. ROLLSROYCE Ltd. May 16, 1958 [May 17, 1957], No. 15845/57. Class 40 (1). [Also in Group XXIX] Remote control apparatus for a flap 10 comprises a control lever 1 having tooth features 1a engaging helical tooth formations 2 on a nut member 3, a splined shaft 6 supporting the nut member 3 and rotating therewith, a pinion 27 on the splined shaft operating a rack 26 whereby a servo-control valve 22 which may be replaced by an electric switch system is actuated, an hydraulic or electric motor 16 controlled by the servo-valve or switch, a gear train 18, 19, 21 and 15 driving bevel gears 7, 8 and a screw jack 9 driven by the gear 8 and operating the flap 10. The gear 15 rotates shaft 5 which is in threaded engagement with the nut member 3. Movement of the lever 1 rotates the nut member 3 causing the pinion 27 to move the rack 26 and control valve 22 or switch whereupon the motor drives the gear train 18, 19, 21, 15 to move the flap 10. At the same time the shaft 5 is rotated causing axial and rotary movement of the nut member 3 against the fixed abutments of the teeth 1a in a sense to rotate the pinion 27 to bring the control valve or switch back to its neutral position. In place of the lever and quadrant arrangement shown at 1 a helically-toothed pinion may be provided which is axially movable relative to the nut member 3, but restrained against rotation. The axial movement of this pinion will cause rotation of the nut member 3 in a manner similar to the lever 1. Alternatively the pinion may be borne for rotation whilst being axially located, the selected position of the control member being obtained by rotation of the pinion through a given angle.

Title: Improvements in or relating to a process for the utilization of acetylene and ethylene mixtures
IPC: C07C17/02
Filed: 1953-06-10
Abstract: Trans-dichlorethylene and ethylene dichloride are produced by reacting a mixture of acetylene and ethylene with chlorine in the vapour phase and in the presence of a chlorination catalyst comprising ferric or antimony chloride or activated carbon, condensing the reaction products, and fractionally distilling to separate the two chlorides.  The hydrocarbon feed may be obtained by cracking a paraffinic stock such as ethane, propane or fractions boiling up to naphtha or above at about 1100-1600 DEG  C. Conditions are preferably chosen to yield acetylene and ethylene in about equimolar amounts, these being separated from other reaction products.  The chlorination may be effected at temperatures up to about 350 DEG  C., the chlorine to total gas charge ratio suitably being about 1 to 8-10.  The metal halide catalysts may be used as such or on carriers.
