Title: Method of reproducing polychromatic picture originals
IPC: H04N1/60
Filed: 1970-02-10
Abstract: 1,241,526. Colour reproduction. DR.-ING RUDOLF HELL. 10 Feb., 1970 [25 Feb., 1969], No. 6430/70. Heading H4F. When producing cyan, magenta and yellow separations by photo-electrically scanning an original having bright colours against an offwhite e.g. grey background, a separation signal e.g. the cyan, Fig. 1a, for one of the colours, e.g. red or light yellow may be larger than the separation signals from the background (shown as white, amplitude WN). This will produce errors in the reproduction, and it is thus proposed to use the smallest of the separation signals, if it is above a predetermined threshold S, to produce a "white separation" signal Fig. 1b which in practice is used to produce a "highlight mask". Thus for the red colour the smallest separation signal, i.e. the magenta, is not above the threshold S so no white separation signal is produced causing no accentuation of the red in the reproduction. For the white (grey) colour, all the separation signals are above S and all equal. A large white separation signal is thus produced, causing large accentuation of the background in the reproduction. For the light yellow colour, the yellow separation signal is the smallest and is above S. This produces a small white separation signal, causing a slight accentuation of the light yellow in the reproduction. Diode comparison networks are described, for determining the smallest separation signal, both for when the separation signals are D.C., Fig. 2 (not shown) and A.C. Fig. 3 (not shown).

Abstract: 901,790. Potentiometers. LANDIS & GYR A. G. Feb. 24, 1960 [Feb. 27, 1959], No. 6491/60. Class 37. A self-balancing measuring apparatus comprises an unbalance measuring device receiving an input voltage or current and an output voltage or current derived from a transistor amplifier in series with an indicator; the device operating a movable member responsive to unbalance so as to control the amplifier output in a direction to restore balance; the characteristics of the amplifier being such that its output level for zero input signal lies asymmetrically between the limits of its permissible variation at unbalance. In Fig. 1 a direct current i energizes coil 2 of a measuring device without restoring torque for deflection in opposition to the coil 20 of a measuring device without restoring torque energized in series with indicating instrument 21 and resistor 22 from push-pull D.C. fed transistors 10, 11 having collector loads 17, 18 and 19, respectively, which are energized from preceding push-pull D.C. fed transistors 8, 9 whose bases are energized in push-pull from potentiometers 3, 5 and 4, 6. The opposed torques of coils 2, 20 operate at unbalance to vary differentially the temperatures of temperature variable resistances 3, 4 forming part of the base potentiometers of transistors 8, 9 so that the output of the transistors 10, 11 is such as to restore balance with the input. Coils 2, 20 may be mounted at opposed ends of a pivoted balance beam to encircle corresponding permanent magnets (Fig. 2, not shown). Resistors 17, 18, 19, 22 may be proportioned according to quoted formulµ to give any desired asymmetry of the balance value of the output current between its permissible limits of variation (Figs. 3 to 7, not shown).

Divided out of 666,403. Class 38 (iv). The dimming of an electric discharge lamp L1 having filamentary electrodes E1, E2 and supplied through a ballast impedance B is effected by a variable auto-transformer F<SP>1</SP>2, the secondary W7 of which is in series with the ballast and lamp, whilst the heating of the electrodes is effected through a high reactance transformer W1 having secondary windings W2-W4 connected to the lamp electrodes and the primary connected across the secondary winding of the auto-transformer through a condenser C2 of value such that at a voltage across the secondary winding W7 just below the lamp striking voltage the primary circuit of the heating transformer is at resonance thereby providing maximum heating current. An " earthed " external auxiliary electrode S1 may be provided to improve starting. Each lamp circuit may comprise two or more series connected lamps heated from one transformer and with a single dimmer controlling a number of such circuits. To obtain the same illumination each junction between the series connected lamps may be connected through a resistance R2 and condenser C1 to the neutral supply lead N. Two or more parallel connected lamps may be operated from a single auto-transformer, Fig. 2 (not shown). The Provisional Specification refers to Specification 666,403.

A roller tool, e.g. for finishing cylindrical walls and bores comprises a tool-head or collet having a central circular cylindrical aperture 5 for a sun roll 6 and mountings 7 located radially of the sun roll for planetary working rolls 8 which in operation roll on and between the surface to be finished and the sun roll. In operation the tool is inserted into an undersized bore and either the tool or the work may rotate, the tool being supported by a spindle fixed into a socket in the tool-head and secured by a transverse taper pin and adapted to be mounted in a chuck. The end thrust of the rolls 6 and 8 is taken by hardened bearing balls 11 which are at the front end of the tool recessed into the respective rolls and at the rear end of the tool into the tool head itself. Where the sun roll is large, a number of balls may take its thrust. A cap-plate 14 retains the rolls 6, 8 and the balls 11 in the tool-head and is secured to the body 1 by several screws or a single central screw. Where a single screw is used the shank is recessed to receive a bearing ball for the sun roll which is inserted from the rear of the tool-head and located at the rear by a further bearing ball recessed into a spigot of the tool holder. In a further modification Fig. 10, the working rolls 30 are retained in the tool-head by the engagement of spring-pressed retaining balls with peripheral grooves 32. Similarly, the sun roll 35 is located on a grooved spindle by the engagement of balls 37 in a groove in the spindle and in an interior groove in the roll. In this form the sun roll may be inserted or withdrawn with its spindle 39 by means of a lever 51 which is locked during a working operation.
