Title: System and apparatus for converting colour television signals of the sequential type into signals of the simultaneous type
IPC: H04N11/22
Filed: 1968-04-19
Abstract: 1,206,865. Colour television. COMPAGNIE FRANCAISE THOMSON HOUSTON - HOTCHKISS - BRANDT. 19 April, 1968 [19 April, 1967], No. 18739/68. Heading H4F. Colour television signals of the field or frame sequential type comprising sequential red, blue and green signals forming monochrome fields or frames are converted to signals of the simultaneous type having the same field or frame frequency by storing at least two of the monochrome video signals during their production and then reproducing them in synchronism with the third, which may also be stored or may be produced directly without storage. Apparatus for carrying out this method comprises a magnetic record disc 1 revolving once during every field or frame period and having three concentric tracks 2R, 2B, 2V on to which red, blue and green elementary signals R, B, V from a sequential camera 3 are respectively sequentially recorded by recording devices 5R, 5B, 5V controlled by an electronic switch 4. Each track also has a continuously operating reading head 6R, 6B, 6V and an erasing head 8R, 8B, 8V, a switch 9 causing erasing signals each lasting for one field frame period to be applied successively to the three erasing heads. During each field or frame period one of the tracks 2 receives a signal from the corresponding recording device 5, the previous monochrome signal of the same colour being erased by the corresponding head 8. The remaining two tracks store the other two monochrome signals, and all three signals stored at any given time are simultaneously read out by the heads 6R, 6B, 6V. The switches 4, 9 produce the necessary cycling of recording and erasing across the three tracks. In an alternative arrangement only one recording track is provided, having only a single recording head and erasing head, but with three reading heads accurately sited at 120 degrees to each other. Magnetic tape may also be used for storage. In applying the invention to an interlaced line scanning system each track of the illustrated record disc 1 may be provided with a supplementary recording head or reading head spaced angularly from the first such head 5 or 6 by an amount corresponding to half a line interval. If supplementary recording heads are provided the switch 4 switches successive signals of any particular colour alternately to the main head and to the supplementary head. Alternatively a half-line interval delay line may be switched into the input or output connections in such a sequence as to produce the same effect. In another form the disc 1 may have six tracks, with one set of three tracks being used for even fields and the other set being used for odd fields.

Abstract: 376,943. Radiators for heating buildings. GUIMONT, J. W., 5440, Grove Hill, Lachine, Quebec, and CRANE, Ltd., 1170, Beaver Hall Square, Montreal, both in Canada. July 6, 1931, No. 19430. Convention date, July 5, 1930. [Class 64 (ii).] A radiator for heating buildings has each element so shaped that adjacent elements form between them longitudinal air passages each converging gradually at one side to a narrow outlet communicating with a gradually diverging mouth and, at the opposite side, contracting abruptly to a narrow opening. Elements 12 are connected at top and bottom by header portions 13 having flanges 14 surrounding the flow openings. The upper flanges and flow openings may be dispensed with when adapted for steam heating. Grooves 16 extend longitudinally of each element, the inner wall 18 of each groove making an angle slightly less than 90‹ with the planes 17 between which the element lies, and the outer wall 19 lying at about 90‹ to the inner wall and at a small angle to the planes 17. The outer portions 20 converge gradually and, like the portions 19, may be slightly concave. The side walls 21 of the headers 13 lie between the planes 17 and outwardly of the bottom of the grooves 16, passages 25 which are wider than the openings 23, 24 being formed between the headers. An opening 26 is provided between the two columns of each section. Fig. 7 shows the invention applied to a wall radiator, each section being only half of that previously described, while the air flue 32 is closed at its ends by the connecting flanges. Cool air is drawn in at the bottom of the radiators and, on expansion, is delivered through the vertical openings to the room, the shape of the openings on the outer side of the radiators accelerating its delivery.

Abstract: 1,040,014. Electric analogue calculating. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 22, 1963 [May 22, 1962], No. 19586/62. Heading G4G. In an interpolator comprising at least three input terminals, an output terminal, and a plurality of ganged linear interpolating devices interconnecting the terminals, an input of at least one of the linear interpolating devices is connected to the output of another linear interpolating device to provide interpolation of a higher order than linear. In the example shown co-phased alternating voltages V1, V2 and V3 of, for example, 1000 c.p.s. and corresponding to points X1, X2 and X3 of Fig. 2 are respectively applied to input terminals 1, 2 and 3, Fig. 1. Transformers T1 and T2 are identical and each has four pairs of secondary windings K1A, K1B-K4A, K4B and L1A, L1B-L4A, L4B related in size by powers of two. The windings K and L are selectively connected in series by switches S1A, S1B-S4A, S4B. Transformer T3 is similar to T1 and T2 except that it has twice the number of primary turns. Its primary winding is connected to the sum of the outputs of T1 and T2 and a centre tap on the primary winding is connected in series with its secondary windings which are selectively connected in series by switches S1C-S4C. Switches S1AS1C are operated together, e.g. by a relay armature, and the other switches are similarly operated. The switches S1-S4 are operated according to a cyclic permuting code, the effect of which is that the number of secondary turns of T1 and T3 connected in series follow the sequence - 15, - 13, - 11 ... + 13, +15, whilst T2 follows the same sequence in reverse order. As a result the voltage at the mid-point of the primary of T3 follows the line X4-X6 of Fig. 2. The effect of the switches in the secondary of T3 is to give an output on line 6 which follows the parabolic arcs A and B of Fig. 2.

Title: Process for improving the adhesive strength of shaped structures made of polyesters
IPC: D06M15/356
Filed: 1959-06-08
Abstract: Improvement of the adhesion to rubber of shaped structures such as fibres, filaments, monofils, bristles and foils of high molecular linear polyesters of aromatic or cyclohexane dicarboxylic acids and dihydric alcohols in making articles such as tyres and belts reinforced by the polyester structures is obtained by preliminarily treating the polyester structure with an aqueous dispersion of natural or synthetic rubber containing a water-soluble precondensate of a monohydric or polyhydric phenol with formaldehyde, free formaldehyde and an inorganic or organic base, drying, treating with an anhydrous solution of a polyisocyanate, e.g. diphenylmethane-4;41-diisocyanate, toluylene diisocyanate or triphenylmethane-4;41;411-triisocyanate, in an organic solvent, e.g. methylene chloride, ethylene chloride, chlorobenzene or methyl ethyl ketone, having no effect on the isocyanate, and again drying.  The polyester structure may, before treatment with the aqueous dispersion, be treated with a fatty acid amide. According to the example, a tyre cord of polyethylene terephthalate silk is drawn through an aqueous dispersion of a copolymer of vinyl pyridine, butadiene and styrene, containing resorcinol-formaldehyde, formaldehyde and ammonia, dried in air at 180 DEG C., drawn through a methylene chloride solution of triphenylmethane-4;41;411-triisocyanate, dried in air at 180 DEG C., and embedded in a tyre carcass mix, which is vulcanized for 45 min. at 143 DEG C.  Treated polyester structures for storage before use may be coated with polychlorobutadiene or a copolymer of polychlorobutadiene with another olefine dissolved in a anhydrous organic solvent.
