Patent GB-505694-A (GB)
IPC: G03C7/14
Abstract: 505,694. Colour kinematography and photography. BOCCA, C.; and RUDATIS, D. Jan. 31, 1938, No. 2982. [Classes 97 (i) and 98 (ii)] In order to obtain coloured projected images, the parts of the image to be projected which correspond to a particular primary colour are provided with refracting elements of such form and direction that thev deviate the light in a direction different from that due to the refraction from similar elements relating to the other primary colours of the polychromatic selection employed, the orientation of the refraction plane being different for each of the primary colours, and the projection-being effected by intercepting the light which is not refracted by the said elements and colouring the refracted light by filters placed in the plane in which real images of the luminous source are formed. In order to obtain the image for projection, the subject to be reproduced is photographed through three primary-colour filters, and from each of the colour-record negatives so obtained a diapositive is printed on a goffered layer constituted by a, sensitised colloid, the goffering consisting of a series of refracting elements having different orientations for the three colours. The positive is washed to remove the unaffected colloid so that there remains a quantity of colloid varying from point to point in accordance with the intensity of the luminous impreesion. These copies can be hardened to form matrices and the image for projection is then obtained by impressing the three copies in succession, and in such a manner that corresponding points wilt be superposed, upon any plastic material which will be hardened after it has recieved the impression. The refracting elements may be prismatic or lenticular. Fig. 2 shows the action of prismatic elements A, the parallel light incident on the film being deviated by the elements A to form two parallel beams which are focused'by an objective 0 to form images L1, L<1>1 of the luminous source. Using three sets of refracting elements, six images will thus be produced arranged as shown in Fig. 3. The beams are coloured by filters disposed in ,the focal plane F, and in this plane there may also be provided a screen for cutting out those rays which have not been refracted. A black and white image may be added. to the goffered transparent image used for projection.

Title: Processing circuit for chromatic television signals
IPC: H04N9/465
Filed: 1974-11-27
Abstract: 1490354 Colour television INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 27 Nov 1974 [7 Dec 1973] 51346/74 Heading H4F A PAL switch 17 in a colour television receiver is controlled by a switching voltage from a generator 8, this switching voltage also controlling a gate 10 situated between a phase comparator 9 and a subcarrier regenerator 11. Gate 10 is controlled to pass signals during those line periods in which the output of a 45 degree phase shifter 15 is passed, by PAL switch 17, directly to R-Y demodulator 3. Subcarrier regenerator 11 produces an output in quadrature with the bursts received during the line periods in which gate 10 passes signals. If the phase of generator 8 is "correct", subcarrier regenerator 11 produces an output at 45 degrees with respect to the B-Y modulation axis. In the line periods that gate 10 blocks signals, phase comparator 9 provides a negative output which, through a low-pass filter 12, blocks a gate 13 to leave the operation of generator 8 undisturbed. If the phase of generator 8 is "wrong", subcarrier regenerator 11 produces an output at 135 degrees with respect to the B-Y modulation axis. In the line periods that gate 10 blocks signals phase comparator 9 provides a positive output which, through filter 12, opens gate 13, to pass a pulse from a generator 14 to generator 8 to reset it. In an alternative embodiment generator 14 is replaced by a half-line frequency selective circuit (19, Fig. 2, not shown) having its input connected to the output of phase comparator 9. In either of the above embodiments the gate 13 may be omitted, the output of low-pass filter 12 or the half-line frequency selective circuit (19) being used to control the generator 8 directly or, in the latter case, via a phase comparator receiving inputs from the generator 8 and the half-line frequency selective circuit (19).

Abstract: 1,095,907. Aerials; diversity reception systems; radio transmitting systems. MARCONI CO. Ltd. Oct. 5, 1966 [Dec. 8, 1965], No. 52142/65. Headings H4A and H4L. An H.F. aerial system comprises two logperiodic aerial arrays 1A, 2A, Fig. 1, which incline towards each other at 90 degrees and which are each at 45 degrees to the horizontal. The respective feeders 1A1, 2A1 of the arrays 1A, 2A are connected to the ports IN1 and IN2 of a hybrid circuit arrangement, and a combination output signal is selected by a switch S from one or other of ports OUT1 and OUT2 of the hybrid. Each log-periodic array may comprise a plurality of dipole elements or may consist of rectangular loops as described in Specification 976,870. The loops are composed of wires (W1), (W2), Fig. 2 (not shown), each formed in a rectangular zig-zag and connected to one of the two wires of the array feeder. The ends of the loops remote from the feeders are taken through triangular insulators (T) which provide means for the connection of support ropes. The lower ends of the arrays are secured by the support ropes to lower catenary ropes 1W, 2W, Fig. 1, slung between pairs of supports 1S, 2S, whilst their upper ends are similarly secured to an upper catenary rope W slung between a stub mast M2 and a higher mast M1. A hybrid circuit arrangement for reception may comprise a resistance network in which an in-phase combination of vertically polarized signals having a low angle of elevation above the horizon appears at the terminals OUT1, and an anti-phase combination of horizontally polarized signals having a higher angle of elevation above the horizon appears at the terminals OUT2. Adjustable delay circuits may be provided after the hybrid and the outputs may be selected by the switch S for simple diversity reception, or they may be combined in any desired manner, and automatic selection means may be provided. Alternatively, the two outputs from the hybrid may be fed to separate detecting circuits before being so selected or combined. In a transmitting system, using a suitable kind of hybrid circuit arrangement, energization of the arrays by feeding one port will give radiation at a low angle of elevation, whilst feeding the other port will give radiation at a higher angle of elevation.

Abstract: 1418624 Turbine and compressor blades SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 20 Nov 1967 [24 Nov 1966] 52746/67 Heading FIT  A hollow turbine or compressor blade has at least one primary passage and a plurality of discrete rectilinear secondary passages extending each with a predetermined orientation between the primary passage(s) and the outer surface of the blade, the secondary passages being individually pierced in the blade material by means of an electron beam. Very narrow passages (e.g. > 0.4 mm diameter) may be pierced, due to the high degree of focusing which it is possible to achieve in an electron beam. Successive piercing of the passages is carried out using an electron gun, the blade being held in a known kind of fixture which enables linear displacement of the blade parallel to its own axis, and if required, simultaneous angular displacement, to be effected. In this way it is possible to arrange that the axes of the different passages, whose exit orifices are all distributed on one and the same straight line or curve, make predetermined angles, e.g. a constant angle, with the respective planes tangential to the surface of the blade at the points of piercing. The secondary passages are preferably of circular crosssection, but may be of slot form. In the case of the blade illustrated in Fig. 2, there are provided two series of secondary passages 5 opening on to the concave surface of the blade in the neighbourhood of the leading edge, and two series of secondary passages 5 opening on to the convex surface 7 of the blade, the passages in both series being inclined towards the trailing edge. The diameter of the concave surface passages is 0.3 mm while that of the convex surface passages is 0.4 mm. The total number of secondary passages is 100.
