Title: Improvements in or relating to inductance coils comprising a ferro-magnetic core of highly-permeable ferrite
IPC: H01F29/14
Filed: 1951-04-17
Abstract: 708,121. Inductances. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 17,1951 [April 20, 1950], No. 8991/51. Drawings to Specification. Class 38(2) In an inductance coil for signal frequencies exceeding 10 KE/sec, a ferromagnetic core of ferrite with a loss angle less than 0.06 and a Curie temperature greater than 80‹C is premagnetized by a constant magnetic field of such valve that the inductance of the coil is substantially independent of temperature. This field, which may be produced by a permanent magnet, is preferably at right angles to the field produced within the core by the signals. Both the permeability and the losses of the material are approximately halved. The core dimensions may be chosen so that loss increase from mechanical resonance is avoided. An inductance, may have a core part with a positive temperature coefficient combined with a part with such a value of premagnetization field that it has a negative temperature coefficient, so that the coefficient overall is zero. Specifications 708,127, 708,131, 708,132, 708,133, 708,134 708,135, 708,136, 708,137 and 708,140 are referred to.

Title: Improvements in the production of esters of hydroxylcontaining cellulose derivatives
Inventor: LAMBORN BAYARD THOMAS
IPC: C08B3/02
Filed: 1952-04-08
Abstract: The process of the parent Specification, in which certain perchlorate catalysts are used in the acylation of cellulose, is applied to the solution acylation of cellulose derivatives containing hydroxyl groups replaceable by acyl groups.  A cellulose ether containing free hydroxyl groups may be acylated to introduce acetyl, propionyl, butyryl, caproyl, stearyl, crotonyl or phthalyl groups.  Methyl, ethyl, hydroxyethyl, carboxymethyl, allyl and benzyl cellulose ethers may thus be acylated to form cellulose ether-esters.  In an example, a fibrous hydroxyethyl cellulose is pretreated with acetic acid and allowed to stand at room temperature for two days.  The pretreated cellulose ether is impregnated with an acetylation mixture made by mixing acetic anhydride, methylene chloride, perchloric acid and zinc chloride and cooling to about 5 DEG  C.  The mixture of cellulose ether and acetylation mixture is placed in a reaction vessel and the temperature is brought to 35 DEG  C.  A fibre-free solution is obtained in about 3.5 hours.  Instead of the mixture of perchloric acid and zinc chloride there may be used as catalyst another equilibrium mixture of perchloric acid and a metallic salt of hydrochloric, hydrobromic, phosphoric or a sulphonic acid, or an equilibrium mixture of a metallic perchlorate and hydrochloric, hydrobromic, phosphoric or a sulphonic acid, the metal of the metallic salt or the metallic perchlorate having an electrode potential of between plus 1.7 and minus 0.7 volts.  Specification 463,323 also is referred to.

Title: Treatment of yarns
IPC: D02G1/02
Filed: 1969-02-19
Abstract: 1,217,124. Treating twisted yarns. HEBERLEIN & CO. A.G. 19 Feb., 1969 [20 Feb., 1968], No. 9038/69. Heading D1F. A process for equalising the internal tensions in synthetic textile yarns which have been textured by temporary high-twisting and heat setting in the highly twisted state comprises subjecting the yarn to further temporary high twisting in the direction opposite to that in which it was previously high twisted but without a heat setting treatment in the high twisted state, the yarn being subjected to a heat treatment either before or after the said further temporary high twisting. In a preferred embodiment, a multifilament yarn 2 is fed from a bobbin 1 via feed rollers 3 and a heater 4 to a false twister 5. The heat set highly twisted yarn then passes through feed rollers 6 to a heating device 7, to equalise internal tensions in the yarn, and is taken off by feed rollers 8 rotating at a speed 10-15% slower than that of the feed rollers 6 to allow the yarn to contract. The rollers 8 feed the equalised yam to a second false twister 9, which rotates in the opposite direction to the false twister 5, and the yam is fed to a takeup package 11 by feed rollers 10. The yam is preferably slightly stretched during the second false twist treatment. The heaters 4 and 7 are preferably heated contact surfaces but may be hot air heaters. In an alternative embodiment, the yam after the first false twist and heat setting treatment is wound into a package which is steamed in an autoclave to equalise internal tensions in the yarn. The yam is then taken from the steamed package and passed through a false twister so that a twist is imparted in the opposite direction to the first applied twist, and the yarn is wound into a package. In a further embodiment, the heat treatment to equalise internal tensions may be combined with subsequent necessary yarn treatment processes. Yarns specified are multifilament polyamide or polyester yarns of 100-200 denier.

Title: Method of obtaining potassium and/or sodium ferro-cyanide in the purification of coal gas
IPC: C10K1/12
Filed: 1930-03-24
Abstract: Water soluble potassium and/or sodium ferrocyanides are obtained free from insoluble cyanides in the purification of coal gas from hydrocyanic acid by washing the gas with a suspension of divalent iron compounds in an excess of alkali lye, such as alkali hydroxide or carbonate, the coal gas freed from tar and ammonia but containing carbon dioxide and hydrocyanic acid being washed according to the counter current principle and the excess alkali which is converted into carbonate or bicarbonate being used again in making up fresh wash liquor.  The divalent iron compounds may be obtained by the reaction of ferrous sulphate or chloride with milk of lime, soda, or ammonia preferably at a temperature of 80-90 DEG  C.  The spent liquor is filtered hot and concentrated for the crystallization of the ferrocyanides, any bicarbonate present being decomposed with the evolution of carbon dioxide; any thiocyanic acid or sulphuretted hydrogen present is also driven off in the concentration.  The mother liquor from the crystallization consisting principally of alkali carbonate is returned to the process.  Specifications 10876/02, 26566/02, [both in Class 1, Acids, alkalies, &c.], 109,254 and 181,719, [both in Class 1 (ii), Inorganic compounds, other than &c.], are referred to.

Title: Process of continuous dyeing of textile materials
IPC: D06P1/22
Filed: 1945-04-17
Abstract: Fibres, yarns and fabrics are dyed by a continuous process by subjecting them successively to processes whereby vat dye pigments are applied from a liquid suspension, the greater portion of the liquid is removed from the materials by squeezing, the materials are dried immediately, but only for a short period of time subjected to one or more baths of an alkaline reducing agent, they are then squeezed, and subsequently the reduced vat dye is oxidized on the fibre.  The amount of liquid removed by squeezing before drying may be such that the moisture retained is less than 75 per cent of the weight of the fibres.  The vat dye pigment may be applied by passing the fibres, yarns or fabrics through an immersion box containing the liquid dispersion of the vat pigment, and a substantial portion of the liquid then removed by means of a padder.  In example (1), mercerized bleached cotton poplin is padded with a liquor containing Indanthrene Brown BRA paste, Calcaloid Yellow GCD paste and Calcaloid Grey BD paste, dried by passing through a hot flue, passed firstly through a three-roll pad containing caustic soda and sodium hydrosulphite at 180 DEG  F. and then through a booster box containing a lower concentration of caustic soda and sodium hydrosulphite at 160 DEG  F., soaped, rinsed and folded.  In other examples, mercerized cotton fabrics are similarly dyed, using (2) Ponsol Brown AGG double paste, Ponson Olive GGL paste and Ponsol Golden Orange 4G paste, and (3) Indanthrene Olive TA paste, Carbanthrene Khaki 2G paste and Indanthrene Olive Green BA paste. Specification 578,212 is referred to.
