Filed: 1972-02-08
Abstract: 1329950 Television FERNSEH GmbH 8 Feb 1972 [9 Feb 1971] 5867/72 Heading H4F To compensate for variations in the light emissivity of a flying spot scanner tube 1, Fig. 1, direct light from the tube is directed by mirror 9 to a photo-cell W, to give an output # (1 Œ #), # representing the correct constant luminosity value, and Œ ## the actual variations therefrom. The signal #(1 Œ 8) is fed to a clamping stage 13, controlled by the output of a circuit 12, receiving a short blanking signal H K  as used in the tube 1 and a longer lasting blanking signal A, as used by the rest of the processing equipment, the amount of extension of signal A being shown by dotted lines. Circuit A thus gives a clamping pulse for said extension period thereby coinciding with the first part of the video signal. Said first part of the video signal is thereby clamped to zero such that the output of stage 13 is Œ ##. This is inverted in stage 30 to become # ##, and in mixers M (one for each of the red, blue, green colour channels) is added to a constant k = # to give (# # ##) before being multiplied with the colour signal T#,(1 Œ #) to give T #<SP>2</SP>(1-#<SP>2</SP>) in which the term #<SP>2</SP> is so small as to be ignored.

[Also in Division G6] A device for .handling nuclear fuel elements 4 in a swimming pool reactor 1 and enabling them to be transferred from a box 2 to a box 2a and be inverted in the process comprises a tubular support 6 having a hand wheel 8 and supported by a float 72, the lower end of the support rotatably receiving a shaft 12 to which one jaw 16 of a gripper is fixed. The jaw 16 has a bore 18 aligned with a sleeve 20 fixed to it and pivotably supports at 26 a second jaw 16 controlled by a cable 34 connected through a link 36 to a handle 38. A sleeve 40 slidable within the support 6 has an abutment 42 engaged by a spring 44, the other end of the spring engaging a shoulder 46 on the link 36. The spring 44 tends to move the handle 38 downwards but this is normally prevented by locking ball 56 supported in an aperture in the sleeve 40 and engaging a recess in the handle. The ball 56 is controlled by a spring-biased finger 50 having a groove 54 receiving the ball. In order to pick up a fuel element 4 the device is positioned thereover by the hand wheel 8 and is depressed by the hand wheel so that the fuel element is received in the bore 18; also the finger 50 is depressed causing the ball 56 to further enter the groove 54 and release the handle 38, whereupon the latter moves downwards and a spring-biased plunger 32 closes the jaw 24, a jaw finger 28 entering a slot 22 in the sleeve 20 to engage the fuel element. In order to invert the fuel element the shaft 12 is connected to a pinion 60 engaged by a toothed rack 58 fixed to the lower end of the sleeve 40, the upper end of the sleeve having a further toothed rack 62 engaged by a pinion 64 operated by a handle 66 whereby the sleeve may be slid within the support 6 and the jaws 16, 24 rotated through 180 degrees. A modified gripper for handling horizontally disposed objects is described with reference to Fig. 2 (not shown).

Abstract: 803,018. Fluid-pressure servomotor-control systems. PREPARATION INDUSTRIELLE DES COMBUSTIBLES. Feb. 28, 1955 [March 5, 1954], No. 5908/55. Class 135. A two-stage hydraulic servomotor controlling a densimetric classifying washbox in which materials of different densities are separated, comprises a first fluted hydraulically-balanced core 1, Fig. 1, rotatable in an inner casing 5 and a second fluted hydraulically-balanced core 16 formed integral with the inner casing and rotatable in an outer casing 13. Pairs of oppositely disposed vanes 8, 28, Fig. 2, fixed to the inner casing rotate in chambers 7, 9 respectively formed in the outer casing. On, e.g., clockwise rotation of the core 1 on the raising of a float 25, Fig. 4, consequent upon an increase in the amount of the denser material in a washbox 22, pressure liquid from lines 2 is directed through grooves 4 to the chambers 7 and from the chambers 9 through grooves 11 to exhaust lines 3 so that the casing 5 and hence the second core 16 are also rotated clockwise until the ducts coacting with the grooves 4 and 11 are again closed. Ducts 29 interconnect the chambers 7, 9 so that liquid expelled from the chambers 7 by the vanes 8 is transferred to the chambers 9 to act on the vanes 28. The rotation of the core 16 causes the lines 2, 3 to be connected to the lower and upper sides respectively of the piston of a servomotor 19 to open a valve 21 in the washbox to allow discharge of the denser material and at the same time rotate an arm 23 to re-centre the casing 13 with respect to the core 16.
