Title: Process for dyeing fibres of stereoregular polypropylene
IPC: C09B31/02
Filed: 1963-03-26
Abstract: Fibres of stereoregular polypropylene containing a polyvalent metal compound are treated with an aqueous composition containing an azoic diazo component in the free amine form and with an aqueous composition of a phenolic or enolic coupling components, both the diazo and the coupling components being free of strongly ionisable substituents and thereafter treated with a diazotising composition to effect diazotisation and coupling and the formation of chelate groups between the polyvalent metal atoms and the characteristic <FORM:0985612/D1-D2/1> groups in the azoic dye is promoted.  The polyvalent metals may be Cu, Zn, Ca, Mg, Sr, Ba, Cd, Al, Ti, Sn, Pb, V, Sb, Bi, Mo, Mn, Fe, Co and especially Ni or Cr.  The metal compounds may be inorganic salts, organic salts or organo-metallic compounds (many specified), those exemplified being bis (1-[2-hydroxyethyl]-2-undecyl-2-imidazoline) chromium acetate and nickel phenol-phenolate of bis (p-tetramethylbutyl phenol) sulphide. Many diazo and coupling components are specified which are free from highly ionisable groups, e.g., sulphonic and carboxylic acid, amino-carboxylic and halogen-carboxylic acid groups and salts thereof; they may be substituted with nitro, alkyl, alkoxy, hydroxyalkyl, hydroxy, fluoro, chloro, bromo and iodo substituents or contain amide groups.  The diazo components are most easily absorbed as the free amine at pH 8-12 while the coupling components are most easily absorbed as the free phenol or enol at about pH 7.5, both at temperatures of 180-200 DEG F.  The use of many known dyeing adjuvants, e.g. emulsifying agents, melting agents, carriers and swelling agents (many specified) is mentioned.  In a preferred embodiment the fibres are treated at 180-200 DEG F. with an aqueous bath containing both azoic components first at pH 10-12 and later at pH 6-7 and then rinsed. Diazotisation is then carried out at room temperature and the bath temperature is then varied to 160-180 DEG F. The fibres are then soaped and rinsed.  Examples are given.

Abstract: 672,086. Laundry systems. PROSPERITY CO., Inc. May 16, 1950 [July 20, 1949], No. 12218/50. Class 138 (ii). A method of continuously and progressively laundering, ironing and processing individual family bundles of laundry, consists in re-assembling the main and sub-classes of each individual family bundle after the main class has been individually machine washed and dried, and the sub-classes (requiring different respective washing treatments) have been washed and dried with the respective sub-classes of a number of other bundles and sorted therefrom. Family bundles of washing are weighed successively on scales 12 and undergo a colour test and each is then broken up on a table 11 into a main class (including articles which will not shrink and the colour of which will not run) and a subclass or classes (including articles the colour of which will run if washed in too hot water, and shrinkable articles). The main class of each bundle proceeds in a respective cart 14 to a respective washer 13 (one, only, shown in the Figure) which may be automatic or semiautomatic, and thence successively to an hydro extractor 17 and to a " shake out " tumbler 21. The sub-classes of several family bundles are grouped together according to the respective types of article. All the sub-classes of one type are then dealt with together in a washing machine 15 and hydro extractor 20 and are then sorted out on hooks on a rack 23. A further series of machines 15, 20 (not shown), are provided for each of the other types of subclasses. When the main class of a particular family's bundle arrives at the tumbler 21 the various sub-classes of that bundle, which have previously arrived at, and have been waiting on, the rack 23 are united in the tumbler with the main class. The articles are then sorted out on a table 25 into groups which relate to the respective types of succeeding operations, (e.g. the particular kind of ioning and starching required). They are then disposed in these groups on a carrier 26. A target 31 carrying a number relating to the particular family bundle (1 as shown) is hooked on the carrier and carries tags 32 relating to the various types of sub-classes included in the bundle. Tags 33 relate to the degree of starch required. Flags 34 are provided for labelling each respective group on the carrier 26. The carrier then proceeds successively to a dry tumbler 27, starching station II, flatwork ironer station III, station IV at which are sock forms and handkerchief presses, further pressing stations V, VI and VII for shirts and other articles. The carrier is finally emptied at a wrapping table VII.

Abstract: 275,724. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). May 12, 1926. 1: 3 - di(4<1> - alkoxyphenylamino)naphthalene and its derivatives are produced by heating a naphthylamine sulphonic acid having a sulpho group in the meta position to the amino group with a p-alkoxyaniline or a derivative thereof. According to an example the acid sodium salt of 1-naphthylamine-3: 8-disulphonic acid is introduced into molten 4-anisidine and the mass stirred. Water and 4-anisidinehydrochloride are added and the mixture heated until evolution of sulphur dioxide ceases. On pouring into dilute hydrochloric acid and ice, 1 : 3-di(4'-methoxyphenylamino)naphthalene-8-sulphonic acid is obtained by filtering and washing. Similarly by using the mono- or di-sodium salt of 1-naphthylamine-3: 6: 8-trisulphonic acid, the 1: 3-di(4'- methoxyphenylamino)naphthalene - 6: 8 - disul - phonic acid is obtained. Naphthophenazine dyestuffs are produced from 1 : 3-di(4<1>-alkoxyphhenylamino)napthalenes or derivatives thereof by condensation with an aromatic nitroso compound or by joint oxidation with 1 : 4-phenylenediamine or a derivative thereof which contains at least one free amino group. In an example, 1 : 3- :di (4<1>-methoxyphenylamino) naphthadene-8-sulphonic acid in neutral alcoholic solution is oxidized at elevated temperature in the presence of the sodium salt of 4-aminodimethylaniline-3-sulphonic acid by means of air, a copper oxide ammonia solution having been added. The dyestuff which is precipitated dyes wool in greenish-blue shades fast to light. In a further example, p-nitrosodimethylaniline is condensed with 1 : 3-di(4<1>-methoxyphenylamino) naphthalene 6 : 8-disulphonic acid by boiling in alcoholic solution.

Title: Improvements in or relating to methods of dispersing fogs and the like
IPC: E01H13/00
Filed: 1953-05-04
Abstract: A method of dispersal of atmospheric fog comprises the introduction, into the fog, of a surface-active agent in order to promote coalescence of the droplets and their precipitation as rain.  Fogs whose droplets carry a negative surface-charge may be treated with cationic surface-active agents such as tetraisoamyl-ammonium chloride, lauryl or stearyl dimethyl benzyl-ammonium chloride, or cetylpyridinium chloride.  Fogs whose droplets are positively-charged may be treated with anionic wetting agents such as long-chain sodium-alkyl sulphates or sulphonates.  The charge-density in the fog may be determined by laboratory analysis and the concentration of surface-active agent required for dispersal may be determined from a calibration chart. p  Non-ionic agents, such as penta-erithritol esters, may also be used, these agents being adsorbed over the droplet-surface to displace the charged ions.  The dosage of ionic wetting agents requires to be exact, in order to avoid a charge-reversal on the fog-droplets, but non-ionic agents may be employed in excess.  The agents may be dispersed, either by volatilization of a solution of the wetting agent in a current of hot air, thus producing a smoke, or by spraying from aircraft or from machines such as are used for fruit-spraying.
