Abstract: 1,151,200. Gas turbine plant. GENERAL ELECTRIC CO. Nov. 9, 1966 [Dec. 15, 1965], No.50171/66. Heading F1G. A method of operating a gas turbine-generator set in standby reserve comprises driving the turbine 3 using the generator 4 as a motor, throttling inlet air to the compressor 1, and extracting compressor air from a higher pressure point and recirculating it through a line 14 to a lower pressure point, to thus reduce the air-flow to the combustion chamber 2 and turbine. The method enables the turbine inlet temperature to be maintained at a high value ready for instant power generation without thermal shock, with minimum fuel supply to the combustion chamber and without surging of the compressor. A valve 15 controls the degree of recirculation which may be between 20 and 45% of the total air-flow through the compressor. The throttle valve 13 in the inlet conduit 6 reduces the compressor inlet pressure to between “ and<SP> 1</SP>/ 5  atmospheric pressure. In modifications, the turbine 3 is connected to generator 4 through a reduction gear or the generator is connected to a separate turbine in flow series with the compressor driving turbine.

Abstract: 1,171,161. Corrected photographic colourseparation positives. J.B. PEATY. Nov. 14, 1966, No.50890/66. Heading G2C. Colour-corrected photographic colour separation positives for use in graphic colour reproduction are made by (a) forming colour separation negatives, (b) forming colour control negatives which are similar to the colour separation negatives but have been underexposed and overdeveloped to increase the contrast, (c) forming selective positive-negatives by using individual colour components of the light image of the original to be reproduced in register with colour control negatives, (d) forming positives using the separation negatives in register with the selective positive negatives and then (e) registering the positives obtained with their corresponding selective positive negatives. When the conventional red, green and blue colour components of a colour transparency are used to form cyan, magenta, yellow and black colour separation negatives and cyan, magenta and yellow control negatives, up to four selective positive negatives may be made as follows by exposing:- (i) The green component image of the transparency in register with the yellow colour control negative; (ii) the red component image in register with the magenta colour control negative; (iii) the blue component image in register with the cyan colour control negative; and (iv) the green component image in register with the cyan colour control negative. In preparing the positives, the black (or key) separation negative may be registered with selective positivenegatives (ii) or (i) and (ii) together; the cyan separation negative may be registered with selective positive-negative (ii); the magenta separation negative may be registered with selective positivenegatives (i) and (iv); and the yellow separation negative may be registered with the selective positive-negative (iii). The positives obtained are then placed in register with their corresponding selective positive-negatives to obtain the corrected positives, e.g. the yellow positive (that obtained from the yellow separation negative) with selective positive-negative (i); the magenta positive selective positive-negative (ii) and the cyan positive with selective positive-negative (iii).

Alternatively one or more lines may be selected from each field, and similarly read into and out of a register at differing speeds and displayed on an elongated cathode-ray tube screen having its line scan direction parallel to its long dimension. When successive "stripes" are caused to be displayed, the correct position of each line portion is determined by comparator 78 which compares the outputs of a horizontal counter 36 which counts clock pulses and is reset by the horizontal sync. signal and a vertical counter 76 whose count is incremented by two or four at the end of each frame, the output of the comparator 78 causing sixteen samples of information to be read into shift register 134 when the counter outputs are the same, the incrementation of the count of vertical counter 76 causing the change in the "stripe" displayed as indicated by the arrow in Fig. 2. Cathode-ray tube 84 may be replaced by an electron beam recorder.  The information recorded may be alphanumeric information from a computer, or video formation.
