Patent GB-1265253-A (GB)
IPC: G06K15/16
Filed: 1970-07-13
Abstract: 1,265,253. Printers. BURROUGHS CORP. 13 July, 1970 [24 July, 1969], No. 33872/70. Heading G4H. In a line printer marks referencing printing lines of each page of continuous stationery are preprinted down one edge of each page or are printed on a format control loop. In either case, pulses generated by photo-electrically scanning the marks as the paper moves are counted and the paper stopped when the count equals a binary number transmitted from a computer to select the print line. In the arrangement of Fig. 5, line marks represented by doubledashes 43, 45 either side of the paper sprocket holes, or single dashes on one side only, are scanned by two photo-cells in a scanner 41 which are connected to a logic arrangement 87, 93, 97 and 105 to generate a pulse on line 117 for each double-dash to clock on counter 113. The counter is reset by the unique end of page single mark in the left-hand column via line 115. Binary numbers from a computer 39 are stored in register 47. Decoder 109 decodes numbers from 1 to 12 each of which identifies a particular one of the double-dash marks. Upon coincidence with the counter and decoder a comparator 121 signals a brake/clutch mechanism 25 to stop the paper advancing. Binary numbers 13, 14 and 15 decoded in decoders 125, 133 and 139 respectively, advance the paper by one line, two lines or to the next double-dash mark. The receipt of a fresh number in register 47 starts the paper moving again. The sensing head, shown in Fig. 3, consists of two infra-red radiation sources and two phototransistors mounted in a block 65 which is supported in a frame 63 attached to a support 41. The block 65 is adjustable selective to the marks by screw 69 and the support 41 swings out to admit fresh stationery. If a format control tape is used (Fig. 6, not shown) it is laid on top of the print paper in registration with the sprocket wheel and loops over the support 41.

Abstract: 1294894 Adaptive control TEXAS INSTRUMENTS INC 18 Nov 1969 [23 Dec 1968] 56367/69 Heading G3R [Also in Divisions G4 H4] During a learning mode an adaptive processor is fed with training signals which include an input signal and with signals representing the desired responser to those signals. An error signal, representing the difference between the actual response and the desired response is generated. The error signal adjusts the gain of amplifiers to control the contribution to the training process of the training signals, thereby reducing the inertia to response after long training. In one embodiment, Fig.2, quantizer 11 is fed with an input signal u (i) and quantizer 14 by a signal x (i-1) which is the output of the processor during the preceding cycle. The uantizers select a storage capacitor, e.g. 51,71, in both of two storage matrices 12,13 by way of gates, e.g. 90, 91. Each capacitor in matrix 12 stores the previous values of the output of adder 20 when the capacitor is selected. Each capacitor in matrix 13 stores a signal representing the number of times the corresponding capacitor in matrix 1z has been updated. Each capacitor is associated with a mechanical switch, e.g. 92,95, which connects the capacitor, e.g. 51, first to contact 93 then to 94 so that the capacitor is first read out and then updated. The processor output x(i) is derived by way of normalizer 24 fed by the outputs of adders 20,26. Adder 26 receives a signal from matrix 13 and from amplifier 27b which is fed by a unit source 27. Adder 20 is fed by matrix 12, and via amplifier 23b, by the difference of the previous output x(i-1) of the processor and of the desired output z(i). To develop the error signal which controls the gain of amplifiers 23b, 27b the outputs of the matrices are fed to divider 27c. This feeds subtractor 27g, also fed with the desired response z(i). The subtractor output is rectified and filtered, 27i, 27j, and applied to the amplifiers. When training is completed the training signal inputs to adders 20, 26 are inhibited by opening switches 23a, 27a. Other embodiments, Figs.5 and 6 (not shown), are similar to Figs. 5 and 6 (not shown) in Specification 1264387 which illustrate a model of a plant with several variable inputs, and a system for recognizing boat sounds. In these embodiments error signals are derived by circuits as described above to control the gain of amplifiers which feed training signals derived from storage matrices to adders in the processors.

Abstract: 1295874 Porous fluoro-polymers E I DU PONT DE NEMOURS & CO 25 Nov 1969 [26 Nov 1968] 57715/69 Headings C3C and C3P [Also in Division B2] An object comprises a porous core of (1) fluorine-containing addition polymer, at least the surface of the core, and/or the pores at the surface of the core being coated or filled by (2) an addition copolymer in which substantially all of the recurring units contain fluorine atoms and some of the recurring units contain sulphonyl radicals, the molar proportion of the sulphonyl radicals in (2) being greater than the molar proportion of sulphonyl radicals (if any) in (1). The core may be polytetrafluoroethylene or may be a copolymer of tetrafluoroethylene with no more than 45% by weight of copolymerizable monomer, e.g. hexafluoropropylene or a sulphonyl-containing vinyl monomer. The core may be applicated by extrusion, casting or moulding to a sheet. The coating copolymer may contain units derived from vinyl fluoride, hexafluoropropylene, vinylidene fluoride, trifluorethylene, chlorotrifluoroethylene, a perfluoro (alkyl vinyl ether) and tetrafluoroethylene. The sulphonyl radicals may be SO 2 M (wherein M is F, Cl, OH or amine or OMe wherein Me is akyl metal or quaternary ammonium). The sulphonyl radical may be contained in repeating units of formula (wherein R f  is a bifunctional perfluorinated radical containing 2-8 carbon atoms, S f  is a sulphonyl radical). Preferably the vinyl radical is joined to the R group through an ether linkage. The preferred sulphonyl fluoride-containing copolymer is perfluoro-(3,6-dioxa-4-methyl-7- octenesulphonyl fluoride). The object can be produced by dipping the core in a dispersion or solution of the copolymer (2), removing the solvent for dispersing medium and optionally converting some or all of the sulphonyl groups of the coating copolymer into e.g. sulphonate or sulphonic acid groups. Alternatively polymer (1) may be mixed with up to 50% copolymer (2) and the mixture shaped, e.g. by fabrication, into sheeting. The pores of the core may be open.

It is constructed from stringers 28 attached to a skin 29 so that it may twist; the other doors are of honeycomb sandwich construction. The flat lower doors 10 and 11 slide, guided by tracks 35, 36, 37, 38, in a channel 34 and are coupled together by a pin and bush joint (33), Fig. 2A (not shown). Door 10 is attached to the fuselage by a pivot 32 whilst door 11 is coupled to the upper door 9 at 31. The biasing mechanism, Fig. 5, has two arms 42, 43 pivoted on the fuselage by a common pivot 44 and connected by linkages 49 and 50, 51 to the doors and by a spring mechanism 45 to each other.

The compound sprayed is such as will pyrolize on contact with the hot glass to form the metal oxide, e.g. ferric chloride or cobaltous acetate, and the gas used to maintain the controlled atmosphere may be air. Glass ribbon 1 passes after formation in region 2 to the annealing lehr 4 via spray zone 5, being carried on rollers 3. Suitable gas is passed into the zone through manifolds 9 and exhausted through ducts 10 and butterfly valves 13 to hood 11 and hence to the extraction system 12. The spraying zone is isolated from forming area and annealing lehr by known means, such as raisable wall 14, in which is mounted a manifold 15 supply gast o form a screen, used in conjunction with flexible aprons 16 and 18. Spraying is by means of one or more spray guns 8 which spray through a slot 7 in the stepped ceiling 6. The temperature of the enclosed zone is maintained by heating the gas supplied through manifolds 9 at a value near to that of the hot glass so as to prevent adverse cooling effects.
