Title: Method of photographically making coloured prints of reduced size from lenticular film
Inventor: CAPSTAFF JOHN GEORGE
IPC: G03C7/22
Filed: 1950-10-26
Abstract: 687,742. Colour photography. KODAK, Ltd. Oct. 26, 1950 [Oct. 27, 1949], No. 26112/50 Class 98 (ii). In a method of making from a lenticular film containing a record of the three primary colours of a coloured object, a coloured print of reduced size on a light-sensitive non-lenticular material so sensitized and constructed as to record three images corresponding to the three primary colours, the printing light is passed through the lenticular film and on to the non-lenticular material through an optical system comprising two fixed objectives having between them a fixed tricolour band filter which also acts as a diaphragm for both objectives, the effective aperture of the objective between the filter and the lenticular film being the same as that of the lenticulations, the focal length of the two objectives being proportional to the linear reduction required and the effective apertures of the two objectives being inversely proportional to their focal lengths and the resulting records of the three primary colours are processed to differently-coloured images. As shown, the optical system for producing prints of reduced size from the lenticular film 7 on the three-emulsion layer colour photographic film 2 comprises an objective 4 of the same effective aperture as the lenticulations 6, a three-band colour filter 8 forming the diaphragm for both objectives 4 and 5, and a second objective 5, the ratio of whose focal length to that of the objective 4 is proportional to the reduction required. Either or both of the objectives may have an aperture greater than the effective aperture. The colour picture produced in the non-lenticular film may be of the subtractive type. The lenticular film may have been printed without reduction of size from a non- lenticular colour photographic material, thus enabling a final print of reduced size on non- lenticular colour photographic material to be produced from the latter. Specifications 574,137 and 686,770 are referred to.

Title: Improvements in or relating to automatic gain control circuit arrangements for television receivers
Inventor: MOTHERSOLE PETER LEONARD
IPC: H04N5/53
Filed: 1957-08-26
Abstract: 816,725. Automatic gain control. MULLARD Ltd. Aug. 26, 1957, No. 26837/57. Class 40 (5). In a television A.G.C. circuit of the " sync. cancellation " type, in which a peak rectifier charges a condenser during the residual " porch " periods, an additional charge is added during the " back porch" periods which is sufficient to prevent the voltage across the condenser decaying below the " porch " level during the line scanning time. Inverted demodulated video signals, i.e. having the sync pulses positive-going, are applied via a series resistor R1 to the grid of a cathode-follower peak rectifier V1A which charges condenser C3, the sync. pulses in the waveform being cancelled out by inverted sync. pulses of greater amplitude which are derived from the sync. separator (not shown) via condenser C2 and resistor R2. The charge on condenser C3 is proportional to the height of the black level and decays during the line periods, due to leak resistor R3; it is prevented from falling below the black level by adding to the " back-porch " signals at the grid of the valve V1A positive-going pulses of constant amplitude which are derived by differentiation of the sync. pulses. The differentiation is performed by condenser C1 and resistor R1. The A.G.C. voltage across condenser C3 is amplified in a grid-controlled rectifier V1B, being applied to its cathode, while positivegoing line flyback pulses are applied to the anode via condenser C5: the A.G.C. voltage is derived from the anode -via smoothing network R4, C6. The grid of the valve V1B is given a positive bias via resistance network R5, R6, R7, the potentiometer R6 being used as contrast control. The arrangement may also be used for negatively-modulated television signals by interchanging the grid and cathode connections to the valve V1B. Specification 484,202, [Group XL], is referred to.
