The ring is driven from the cylinder gear ring by coaxial pinions. The selectors, which may have differing profiles, are. mounted on a common axis 24; the selected one being held by a pawl engaging a projection 7t. The pawl is released at a reselection by the inner cam face at the projection 7t of a selector moving to the operative position. The levers are mounted on a common axis 21 on a pivoted arm 10. Noses 9a of the levers co-operate with a punched tape 11 engaging a rotatable drum 12 also carried by the arm 10. The axle 20 of the drum carries two ratchets 30, 31, which co-operate with pawls 32, 33 set at selected positions. The pawls are carried, and set, by an arm 36 movable by a cam 40 at the dictates of a pattern chain. When the arm 10 is urged clockwise by spring 19 the drum is rotated in one direction or the other by one or two steps, depending on the position of the pawls. The noses 9a of the levers have been disengaged from the tape by a cam rod 23. At a particular station or stations the arm is selectively urged against the spring by a cam 18, so that a selector is operative. A drum, coaxial with drum 12 may be provided, to select cam-box operation via levers on axle 21.

Abstract: 1,224,214. Colour printing control. EASTMAN KODAK Ltd. April 25, 1968 [April 25, 1967], No. 19654/ 68. Heading G2A. In a colour correction system for photographic printing in cases when colour subject failure may occur due to a predominance of one colour in the original scene, a statistical discriminant function is used to determine the degree of failure likely to occur with a particular colour, and so to compute the proportionate amounts of correction to be applied. Fig. 2 shows the discriminant function computer 23 which receives the inputs 20, 21, 22 from three photo-meters measuring the large area transmission density of the original negative for red, green, and blue respectively. The illuminant computer 26 receives inputs 24, 25 from photo-meters measuring the green and blue components of the illuminant (in the case of a red subject failure negative), to provide an inhibiting compensation for that proportion of the discriminant computer correction due to a warm illuminant (instead of subject failure). The output from the two computers 23, 26 is combined in an adder circuit 27, and then provided as inputs to the red, green, and blue colour correction circuits 28, 29, 30. The respective outputs of these are voltage analogues of the exposure adjustments required to offset the subject failure effects which the printer would otherwise produce, and are used to control the final exposures.

Abstract: 624,091. Aerials; coupling arrangements. RADIO CORPORATION OF AMERICA. July 8, 1946, No. 20345. Convention date, Aug. 25, 1945. [Classes 40 (v) and 40 (vii)] [Also in Group XL (b)] An ultra-short-wave aerial comprises a resonant cavity formed by a quadrangular conductive base, one wall of which is provided with an elongated slot of a width -small compared with the width of the wall transverse to which and within the box is positioned a conductor for energy transfer between the aerial and associated apparatus. In one arrangement, suitable for mounting flush with the exterior surface of e.g. an aeroplane, an elongated slot 20, Figs. 1 and 2, is formed in the front wall 12 of a conductive box 10 and energy transfer between the aerial and transmitting or receiving apparatus is effected by means of a transmission line TL connected through a socket 52 to one end of a conductor 60 mounted transversely to the slot 20, the other end of conductor 60 being connected through a second socket 52 to a short-circuited stub 73. Variation of the coupling between the cavity and conductor 60 is effected by varying the distance between 60 and the rear wall of the cavity and for this purpose conductor 60 is eccentrically mounted at 62, 63 so that the necessary variation is brought about by rotation of 60. The ends of the slot are isolated by means of transverse slots 22, 24 and the cavity is tuned by adjustment of capacity plates 26, 28, 30. A window 44 of dielectric material, e.g. polystyrene, carried by a bezal member 45, prevents the entry of dust, moisture, &c. Band-pass curves, Fig. 3 (not shown), indicate that the standing wave ratio is less than 1.8 over a frequency range extending from 422 mc/s. to 478 mc/s. In an alternative arrangement, Fig. 4 (not shown), the conductor 60, the sockets 52 and the stub 73 are replaced by a coaxial extension of one of the sockets 52 across the box 10 and the inner conductor of the extension is provided with a capacity plate adapted to co-operate with a similar plate connected to the side wall of the box. In a further arrangement, Figs. 5 and 6, the transmission line is coupled to the cavity by means of a curved and tapered tongue 90, to the apex of which the transmission line is connected and the broad base edge of which is connected with the side wall 16 along its entire length. By suitably selecting the taper and curvature of the tongue 90, a constant input impedance results over a relatively wide frequency band. In another arrangement, Fig. 7 (not shown), the tongue is U-shaped in cross-section and the base portion is connected with the rear wall of the box.

In one embodiment the light paths are formed by an electro-optic device 3. A field lens 5 and fly's eye lens matrix 6 focus the light beam on a corresponding diaphragm aperture. The hologram filters 9 are located in the transform plane of a lens 8. Consequently by switching device 3 a Fourier transform image of the symbol 10 is sequentially superimposed on the filters 9. A lens 15 and detector matrix 16 (e.g. of photodetectors) detects any correlation between symbol 10 and the symbols recorded as the filters 9. In a second embodiment all the apertures of the diaphragm are simultaneously illuminated so that all the filters simultaneously receive a Fourier transform image of the symbol 10. In this case light from source 1 passes the field lens 5, then a matrix (19), Fig.2 (not shown), of phase modulators (e.g. electrooptic devices) inserted before the fly's eye lens matrix. In this latter embodiment the phase modulators give rise to incoherent superposition of the signals from the light paths. Also a number of output signals may be added together to establish logical relationships. Reference has been directed by the Comptroller to Specification 1189443.
