Abstract: 1,256,826. Telescopic booms. WARNER & SWASEY CO. 4 Feb., 1970 [14 Feb., 1969], No. 5265/70. Heading B8H. [Also in Division E1] To permit of establishing and maintaining, as wear occurs, proper tracking of rollers by which each of the telescoping sections 20, 30 of a boom are supported on one another some 40-48 of the rollers are adjustable relative to the section on which they are mounted, each of said adjustably mounted rollers being displaceable relative to its supporting boom section both along and at right angles to the axis of rotation of the roller.

Abstract: 1,259,109. Colour television. E.M.I. Ltd. 14 March, 1969 [30 March, 1968], No. 15452/68. Heading H4F.  The luminance signal Y and the red, green and blue signals R, G and B produced by four colour camera tubes 1-4 are matrixed to device a luminance signal Y<SP>1</SP> for transmission represented by:- where y=aR+bG+cB and is equal to Y over the frequency band occupied by the signal y, i.e. the lower frequency portion of the frequency spectrum in which the colour tubes are operative, and where k, l and m are variable without corresponding variations of the amplitudes of the R, G and B signals which form the signal y. The factors a, b and c are normally 0À30, 0À59 and 0À11 respectively. As shown, variable gain controls 5, 6 and 7 vary the gain (i.e. k, l and m) of the R, G and B signals to compensate for different illuminants which may be deficient or excessive in any or all of the colours, and the variations in gain so produced are neutralized by gain control 8, 9 and 10 (respectively inversely ganged to controls 5, 6 and 7) so that the y signal derived in matrix 11 is maintained equal to Y. Thus, for example, if the illuminant is deficent in red the gain in the red channel may be increased by means of control 5, such that kR represents the red component which the scene would have in a standard illuminant in which Y=R=G=B, i.e. with the deficient illuminant controls 5, 6 and 7 are adjusted so that Y=kR=lG=mB. However, since control 5 in inversely ganged with control 8, the condition Y=y (at low frequencies) is preserved. If limiters are included in the Y, R, G and B channels, they are preferably positioned between the ganged gain controls in the R, G and B channels. Fine colour balance control may be achieved by a joystick coupling via variable impedances to the R, G and B channels near the inputs to the gamma circuits 12, 13 and 14. The signals Y, R, G and B may be derived from three pick-up tubes, the R and B signals being derived from one tube by projecting the red and blue components of the scene on to the upper and lower halves of the tube which is scanned at half the scanning frequency of the other two tubes, the output red and blue signals being alternately delayed by a period equal to the scanning period of the tubes producing the Y and G signals. In a further embodiment for compensating for changes in illuminant the gains at the inputs to gamma circuits 12, 13 and 14 are adjusted, the coefficients in the y equation being unaltered.

Abstract: 1333054 Electron microscopes ASSOCIATED ELECTRICAL INDUSTRIES Ltd 28 Oct 1971 [28 Oct 1970] 51190/70 Heading H1D An electron microscope has an e.m. objective lens and at least three separate electromagnetic projection lenses P 1 , P 2 , P 3 , in tandem, the coil supply having a single control (30) (Fig. 2, not shown) effecting magnification changes by variation of currents to two or more of the lenses such that changes of beam rotation in each lens substantially balance each other out, so that the final image has substantially constant orientation, at least over a range of values of magnification. To achieve orientation balance over a wide range of magnification variations, the magnification is varied over a first range by varying currents to a first combination of lenses, and over a second range by current variations to a second lens combination. The current to the objective lens may be simultaneously varied to maintain focus. The supply may be as Fig. 2 (not shown) including stabilizer circuits. In Fig. 3 (not shown), currents to P 3  and Obj. lens are opposed and similarly currents to P 1 , P 2  respectively effecting overall balance. Variation of resistor R 0  by control (30) effects a trimming adjustment to maintain focus, the small rotational change being balanced by P 3  current changes, P 3  operating near its minimum focal length and not significantly affected by excitation alterations. Minimum magnification is limited by geometric image aberrations, typically 8 Î 10<SP>3</SP>. In a second mode, lower than the lower limit (Fig. 4, not shown), P 2  is inoperative, P 1  and P 3  operate in virtual and real modes to produce "barrel" and "pincushion" distortion respectively balancing out, the lower limit being 4 x 10<SP>3</SP> magnification, control (30) effecting P 1 , P 3 , magnification changes and objective lens trimming, P 1 , P 3  rotation equalling Obj. lens rotation but in opposite sense. In Fig. 5 (not shown), P 1 , P 3  rotations cancel, P 2  operates in virtual mode with constant weak excitation introducing "barrel" distortion to compensate P 3  "pincushion" distortion. Objective lens 100 degree rotation is not compensated by P 3  rotation of 10 degree, the final image being inverted but at constant orientation at 4 Î 10<SP>3</SP> to 8 Î 10<SP>3</SP> magnification. Four lenses are also instanced.
