Title: Process for treating textiles
IPC: D06M13/467
Filed: 1938-07-29
Abstract: 517,474. Quaternary ammonium compounds; waterproofing, softening and anti-crease treatments for textiles. ROGERS, M. A. T., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 29, 1938, Nos. 22534/38 and 7098/39. [Classes 2 (iii) and 15 (ii)] [Also in Group VIII] New quaternary ammonium compounds are made by combining aliphatic or heterocyclic tertiary amines with halogenmethyl compounds of the general formula where R is an aliphatic hydrocarbon radicle containing at least 7 carbon atoms and X is halogen. Such halogen methyl compounds are made by interacting compounds of the formula with dihalogenodimethyl ethers, or with formaldehyde and a hydrogen halide, e.g. hydrogen chloride or bromide, or, in the case of the chlorides, with formaldehyde and phosgene. The R-CO- groups may be derived from caprylic, pelargonic, capric, lauric, myristic, palmitic, oleic, stearic and montanic acids and also from mixtures of acids, such as those derived from coconut oil or palm kernel oils. The tertiary amines specified are trimethylamine, triethylamine, N:N-tetramethylethylenediamine, dimethylcyclohexylamine, diethylclyclohexylamine, pyridine, N-methylpiperidine, and alpha-picoline. In examples: (1) distearyldiaminomethane is reacted with hydrogen chloride and paraformaldehyde, and the chlormethyl compound obtained is condensed with (a) pyridine, (b) triethylamine and (c) trimethylamine, and (2) the diacylaminomethane obtained from a mixture of fatty acids derived from coconut oil is treated with paraformaldehyde and hydrogen chloride, and the product is condensed with pyridine. The products are used for softening or rendering water-repellent textile materials of animal or vegetable origin or composed of regenerated cellulose or of cellulose esters or ethers, by impregnating the materials with a solution or. suspension of the quaternary ammonium compounds in water or an inert organic liquid, and subsequently submitting the impregnated material to a short heat treatment to decompose the ammonium compound. Examples are given of the treatment of calico, viscose and cellulose acetate fabrics, and wool delaine. With natural or regenerated cellulose, the process may also be combined with a crease-resisting treatment, by treating the material with a solution or suspension of one ammonium compound before, simultaneously with, or after a treatment with a medium comprising a partly condensed resinous condensation product derived' from an aldehyde and urea or thiourea or a derivative thereof, or a phenol or an amino-1:3:5-triazine, or with the components of such a resinous condensation product, the treatment being followed by drying and finally by a short heat treatment to decompose the quaternary salt and insolubilize the resin. Examples are given of the application of this treatment to fabrics made of viscose. Specifications 291,473, 291,474, 304,900, [all in Class 2 (iii)], 431,703, 449,243, 458,877, 466,015, 466,817, 477,991, 485,198, 493,920, 495,025, 497,856 and 498,287 are referred to.

Abstract: 1,150,725. Block copolyamides. COURTAULDS Ltd. 26 Aug., 1966 [27 May, 1965], No. 22535/65. Heading C3R. Block copolyamides are produced by reacting a polyamide oligomer having amino end-groups and a M.W. between 1000 and 6000 with (a) a polyfunctional activator in such an amount that for every terminal amino-group in the oligomer there are at least 1À2 functional groups in the activator present and (b) a lactam of formula where n is at least 5, containing an anionic polymerization catalyst. The polyfunctional activator is defined as a compound containing at least 2 functional groups which (i) activate anionic lactam polymerization and (ii) react with primary or secondary amino groups. Compounds specified include diisocyanates and N,N<SP>1</SP>-diacyl bislactams structurally derived from a dicarboxylic acid and a lactam. The oligomer may be a random copolymer. The oligomer may first be reacted with 2 equivalents of the polyfunctional activator followed by reaction with the lactam at 160-200‹ C. In an example a nylon 6/66 oligomer is treated with N,N<SP>1</SP>-terephthalyl biscaprolactam followed by Na in caprolactam. The product is shredded, soaked in glacial acetic acid and extracted with boiling methanol to remove low molecular weight material.

Title: Terminal equipment for a telephone system
IPC: H04B14/00
Filed: 1973-05-15
Abstract: 1431922 Echo suppression KOKUSAI DENSHIN DENWA KK 15 May 1973 [15 May 1972] 23036/73 Heading H4R  In a terminal equipment for a Lincompex telephone system in which speech to be transmitted is compressed and transmitted with a signal indicating the original signal level which is used at the receive end to expand the compressed signal to its original volume range, a comparator 5 is provided which compares the original signal level dependent signal from the transmit side with the signal indicating the original signal level of the incoming signal on the receive side and, when the comparator shows that the receive signal is above the outgoing signal, and the receive signal is above a predetermined reference level, the level indicating signal to be transmitted is changed to a signal corresponding to a low input signal level, causing the expander at the other terminal to provide a low gain, effecting echo suppression. As shown the outgoing speech at terminal 1 passes through delay circuit 10 compressor 11, delay circuit 12 and low pass, e.g. 2700 Hz, filter 13 for transmission together with a signal from frequency modulator 16 whose frequency is governed by the level of the signal at terminal 1, as detected by amplifier rectifier circuit 14, and modified by logarithmic compressor 15. Received speech at terminal 3, passes through filter 24, a fading controller 25, which restores the signal to substantially constant amplitude, a delay circuit 26 and an expander 27, controlled by the incoming level indicating signal after filtering, limiting, and demodulation in 22 and shaping in the reverse logarithmic compressor 23. The received level indicating signal at the output of demodulator 22 is fed to a threshold circuit 8 which, if the received level is above a predetermined value produces a signal which passes through the normally open inhibit gate 7 to a bias circuit 6 which applies a bias voltage to the FM modulator 16 to cause it to set to an output frequency corresponding to a very low level of signal on the outgoing speech signal side. If however the outgoing speech signal level, as indicated by the signal at 112, is above the incoming speech level, as indicated by the signal at the output of demodulator 22, the comparator 5 produces an output to inhibit the application of the output of threshold circuit 8 to the bias circuit 6 and the frequency modulator produces an output which depends on the level of the incoming speech at terminal 1. A switch 9 can be inserted in the outgoing speech signal path to be opened by the output signal of gate 7 when the received signal is above the threshold level and the outgoing signal is below the incoming signal.

Title: Phosphate phosphor
IPC: C09K11/77
Filed: 1966-05-25
Abstract: A phosphor principally comprises phosphate of strontium and/or calcium, additive scandium phosphate, and at least one activator consisting of copper and/or tin, wherein the atom ratio of Sc to alkaline earth metal in the phosphor is from 1:5 to 1:100, preferably 1:10 to 1:40, the atom ratio of total metal to P is from 2.4:2 to 3.0:2, preferably 2.6:2 to 2.9:2, the atom ratio of total activator to P is from 0.001:2 to 0.1:2, preferably 0.005:2 to 0.06:2, and the atom ratio of Cu to P is less than 0.06:2. Manganese may be added to the phosphor in amounts such that the atom ratio of Mn to P is from 0.0005:2 to 0.15:2.  Variation of the phosphor composition within the above ranges enables the spectral output to be controlled; the incorporation of Mn, for instance, produces a pronounced red phosphorescence.  The above phosphors operate at elevated temperatures, e.g. 220 DEG  C., and can therefore be used in HPMV and fluorescent lamps and other applications where U.V. radiation is to be converted to the visible range.  The methods of preparation are given of copper activated, and copper-manganese-activated, calcium-scandium phosphate and strontium-scandium phosphate phosphors, and calcium- or strontium-scandium phosphate activated by tin; in all cases the disclosed starting materials in prescribed quantities are thoroughly blended and fired at 1325 DEG  C. in a slightly reducing atmosphere e.g. nitrogen with 1% to 4% by volume of hydrogen, causing part of the copper, tin or manganese to be present in the cuprous, stannous or manganous states respectively. The Figures (not shown) indicate emission curves for typical phosphors excited by 254 nm radiation.
