Title: Colouring of cellulose ester and ether materials
IPC: C09B15/00
Filed: 1934-01-25
Abstract: Cellulose esters or ethers, dyeing.--Cellulose ester or ether materials are dyed or otherwise coloured in greenish yellow to orange shades, fast to acid and to alkali, by applying thereto a derivative of acridone carrying at least one nitro group with or without further substituents, such as halogen or alkoxy groups. In an example cellulose acetate fibres are dyed a bright yellow, fast to light, acid and alkali, by treating the fibres, preliminarily soaped, for 5 minutes in an aqueous dispersion at 120 DEG  F. of 4-nitroacridone, raising the temperature to 160-200 DEG  F., maintaining this temperature for 30 minutes, rinsing and drying.  The aqueous dispersion is prepared by making up a dry paste or powder by milling the dyestuff with an inert water-soluble material such as sugar, soap, Glauber's salt, common salt, dextrin or a mixture thereof, with or without a dispersing agent, such as an alkylated naphthalenesulphonic acid or a salt thereof, sulphonated ricinoleic acid, an abietene sulphonic acid or a salt thereof, rosin soap, aldehyde-sulphoaryl condensation products, dry sulphite waste concentrates &c., stirring the paste or powder into a soap solution to produce a smooth paste, stirring this into hot water and diluting. A table is also given showing the colour, the affinity for cellulose acetate fibre and the fastness to light of the dyeings with the use of the 2- and 3- nitro-, 2- and 6- methoxy-4-nitro-, 8-ethoxy-4-nitro-, and the mono- and dibrominated 4-nitro-derivatives.  Specification 275,752, [Class 15 (ii)], is referred to.  Acridine dyes.--2-Methoxy-4-nitroacridone is obtained by ring closure, by fusion with aluminium chloride, of the chloride of the acid obtained by condensation of anthranilic acid with 4-chloro-3-nitroanisol, obtained from 4-amino-3-nitroanisol by the Sandmeyer reaction.  6-Methoxy-and 8-ethoxy 4-nitroacridones are obtained by similar ring closure of the chlorides of the acids obtained by condensation in hot amyl alcohol of 2-bromo-3-nitrobenzoic acid with o-anisidine and p-phenetidine respectively.  Mono- and di-brominated 4-nitroacridones are obtained by brominating 4-nitroacridone in boiling acetic acid.  The Specification as open to inspection under Sect. 91 comprises also the use of any nitro- or amino-acridones with or without further substituents, such as halogen, nitro, amino, alkyl, hydroxy or alkoxy groups and specifies the use of the 4-methyl-1-nitro-, 2-methyl-4-nitro-, 2- and 4-amino-, 2 : 8-diamino- and the 2 : 4-, 2 : 8-, 4 : 6- and 4 : 7-dinitro-derivatives.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to radio beacons and beacon systems
IPC: G01S1/50
Filed: 1947-02-07
Abstract: 642,183. Radio navigation. PHILIPS LAMPS, Ltd. Feb. 7, 1947, No. 3674. Convention date, Feb. 5, 1944. Addition to 642,181. [Class 40 (vii)] Relates to omni-directional phase beacon systems as described in the parent Specification for enabling a mobile receiver to determine its bearing relative to the beacon in which the beacon radiates two fields modulated respectively with harmonically-related frequencies the phase of the lower modulation frequency w being proportional to azimuth and the phase of the higher modulation frequency nw being independent of azimuth, means being provided at the receiver for comparing the phases of the demodulated signals to obtain a quantity which is indicative of the bearing # and which is a function of n# where n is the ratio of the modulation -frequencies. The accuracy of such a system is increased by making n large but this results in n ambiguities in the 360 degree range of bearings and according to the present invention the ambiguities are resolved by radiating a third field modulated by a frequency ¢w), 2w or 2nw, the modulation phase of this field being also azimuth dependent. At the receiver the modulation of the third field is compared in phase with that of the first or second fields to give an unambiguous but less accurate indication of the bearing #. At the beacon illustrated in Fig. 1 (not shown), the modulation frequency of the third field is 2w and at the receiver the three modulation signals are separated by filters 25, 26 and 27. When the switches 29 and 30 are in the upper position as shown, the signal of frequency w from 26 is frequency multiplied by a factor n at 28 and compared in phase in the meter 31 with the signal of frequency nw from 26 as described in the parent Specification to give an accurate but ambiguous indication of # and with the switches 29 and 30 in the lower position the signal of frequency w is frequency doubled at 32 and compared in phase with the signal of frequency 2w from 27 to give an unambiguous indication of #. Alternatively the phase angles may be determined by producing Lissajous figures on a cathode-ray tube as described in the parent Specification. Specifications 642,094 and 642,182 also are referred to. According to the Specification as open to inspection under Sect. 91 the modulation frequency of the third field having a bearing dependent phase may also be ¢nw, Nw or Nnw where N is an integer greater than 2 or alternatively the modulation phase of the third field may be independent of bearing the modulation frequency being w/m where m is an integer greater than unity. This subjectmatter does not appear in the Specification as accepted.

Filed: 1966-01-27
Abstract: 1,140,391. Quilted laminates. J. PUFAHL. 27 Jan., 1966, No. 3678/66. Heading B5N A contoured multi-ply material comprises a sheet 13 of an elastic base material, and an overlying layer 24 of fabric secured by adhesive to the base material in selected areas whilst the base material was under stress, the overlying layer 24 of fabric being gathered in areas bounded by the selected areas upon relief of stress of the base material to form a contoured surface. In apparatus, Fig. 3, for making the material elastic base material 13, e.g. of an elastic plastics such as polyurethane foam or stretch nylon is fed between rollers 15, 16, the roller 16 applying to the material 13 over selected areas adhesive from a bath 20. The adhesive may be applied along diagonal lines 10, 11 (see Fig. 6) or form the outlines of rosettes or other ornamental figures. The material 13 then passes between a laminating roller 23 and a pressure roller 26, these two rollers having a peripheral speed greater than that of rollers 15, 16 so that the material 13 is stretched, preferably 5-10%, between the two pairs of rollers. The layer 24 of e.g. woven natural and synthetic material, is applied to the material 13 by the roller 26, and the multiply material so formed is fed by rollers 29-32 having the same peripheral speed as rollers 23, 26 to maintain the material 13 in a stretched state until the adhesive has dried. The stress on material 13 is then relieved to produce a fabric having gathered areas 12, Fig. 6, between the adhesive areas. To accelerate drying of the adhesive the rollers 29-32 may be heated, and, as shown the roller 23 is heated by radiant heaters 27 and the fabric is heated by a radiant heater 28. If desired the roller 23 is hollow and heated by passing steam through it. The apparatus may be modified to apply adhesive to both sides of the material 13 in which case an overlying layer of material is applied to each side, thus forming a 3-ply laminate having two contoured surfaces.

Abstract: 1,131,468. Statistical records. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 Jan., 1966 [5 Feb., 1965], No. 3698/66. Heading G4M. A record card or tape is impervious to light along the recording tracks except at the bit positions, and information is recorded by covering selected bit positions with an opaque material. Recording may be by means of stamps, brushes or nozzles and may be effected while the record is moving. Such a record may be sensed photo-electrically in a conventional manner, light passing through those bit positions which have not been covered. The covering material may be made conductive, magnetic, light reflective or fluorescent, and this additional property may be utilized in conjunction with appropriate sensing apparatus to provide signals which are complementary to those produced by the sensing of the transparent bit positions, e.g. for checking purposes. Alternatively, where at least one bit position per column or row is covered, the width of covering material deposited may be varied to record further information, e.g. in Morse code, which is retrievable by a set of sensing devices connected in parallel.
