IPC: D06M13/50
Filed: 1975-10-31
Abstract: 1535506 Flame retardancy I W S NOMINEE CO Ltd 31 Oct 1975 [1 Nov 1974] 30066/78 Divided out of 1535505 Heading DIP The flame-retardance of keratinous material is increased by applying to the material at least one water soluble compound of titanium, zirconium, tungsten, antimony, tin or zinc containing the metal in a complex anion and dissolved at least partly in the aqueous phase of a water and organic solvent emulsion. The emulsion is preferably applied at a pH below 3, at a temperature between 10‹C and the boiling point of the solvent for a period of 5 to 16 minutes so as to provide 1-6% of the complex on the fabric. The material may be solvent scoured before and after the treatment. Finally the material may be steamed e.g. in a decatizer. The complex metathferous anion may be added to the solution as such or it may be formed in the composition by the addition of its components, or it may occur in the composition by molecular rearrangement of compounds not nominally or apparently containing the metal in a complex anion. Fluoroborates, for example behave under acid conditions as fluorometallates. Wool, wool/cotton and wool/polyester blends in various forms may be treated.

Title: Process for recovering metals contained in ores
IPC: C22B3/06
Filed: 1921-11-11
Abstract: Lead is extracted from ores by first converting it to sulphate, leaching the product with a chloride solution, and continuously precipitating the lead from the resulting solution on a metal such as iron.  The process may be combined with the recovery in successive stages of the various metals contained in complex ores. In a process for the treatment of sulphide ores containing copper, zinc, lead, silver, and gold, the ores are crushed, roasted, and leached with sulphuric acid to recover copper aud zinc, the solution of these metals being electrolyzed or otherwise treated for the recovery of the metals.  The residues after the removal of the copper and zinc are treated with hot sodium chloride solution, the solution of lead chloride being continuously drawn off and precipitated on iron or other metal preferably in the form of dust.  The ferrous chloride solution formed is used with or without sodium chloride as a solvent for further lead sulphate. The residues from the extraction of the lead are treated with cyanide for the extraction of gold and silver, the metals being precipitated from the cyanide solution on zinc dust. Silver may be recovered along with the lead by roasting the ore so as to convert both the lead and silver to sulphates, leaching with chloride, and precipitating with iron.  The extraction of the zinc and copper from the complex ores may be effected as described in Specification 26138/13, [Class 82 (i), Metals, Extracting &c.].

Abstract: 304,150. I. G. Farbenindustrie Akt.- Ges. Jan. 14, 1928, [Convention date]. Fatty acids, obtaining; mineral oils and waxes, extracting etc.; soaps.-Waxes such as bees wax, montan wax, and wool fat are separated into two parts :-the corresponding acids and a mixture of the hydrocarbons and alcohols, by saponifying. atomizing the product so as to produce a dry powder, extracting with solvents, and acidifying the soaps. For example; (1) 11.8 kilograms of beeswax are stirred in an autoclave with 4 kilograins of 23.5 per cent caustic soda at 175‹ C. and 8 atmospheres for 8 hours. The entire mass is atomized, and the light yellow powder obtained extracted with benzene. The residue is then acidified; 51 per cent of acids are obtained. (2) 18.7 kilograms of dehydrated crude wool fat are stirred in an autoclave for 6 hours at 182‹ C. and 8 atmospheres with 6.4 kilograms of 30 per cent caustic soda. 'The product is blown out and atomized, and the brown flocculent soap extracted with acetone. 64 per cent of crude fatty acid is obtained by treating the residual soap with mineral acid. The caustic soda may be replaced by oxides or hydroxides of alkaline earth or other metals in aqueous alcoholic solution or suspension. Atomization and drying may be assisted by adding auxiliary substances, e.g. sodium sulphate, kieselguhr, charcoal, sawdust, or pumice, before or after saponification, by the action of hot gases or vapours, e.g. air, nitrogen, carbon dioxide, or superheated steam, and by reducing the pressure in the atomizing chamber.

Title: Improvements in or relating to a modulation system
IPC: H03K7/00
Filed: 1948-11-25
Abstract: 669,320. Phase modulation; valve amplifying circuits. MOTOROLA, Inc. Nov. 25, 1948 [March 22, 1948; April 2, 1948], Nos. 30608/48 and 30609/48. Classes.40 (v) and 40 (vi). To prevent excessive frequency deviation of the carrier in a phase-modulated transmitter, due to the presence of steep-fronted highfrequency components in the audio modulating signal, the strength of that signal is automatically controlled according to the frequency and amplitude of its components before it is applied to the phase modulator. In Fig. 2, the audio signal from a source 10 is amplified in a variable-gain valve 20 and applied to the phase modulator 12. The signal is also fed to an auxiliary amplifier 21, whose output taken across the inductor 34 is rectified at 35. The D.C. voltage across the load resistor 36 is fed in negative sense to a gainadjusting grid of the main amplifier 20, and as this voltage is, owing to the differentiating function of the inductor 34, dependent on the frequency as well as the amplitude of the audio signal, excessive frequency deviation of the carrier is prevented. In a modified circuit, Fig. 3 (not shown), input to the auxiliary amplifier 21 is taken from the output of the valve 20 through a differentiating condenserresistance network, and the output from the auxiliary amplifier is taken through a transformer to a rectifier which is biased so as to be non-responsive to weak inputs. In a further modification, Fig. 5, audio input is applied at 110, 111 through a differentiating network 113, 114 to the grid of an amplifier 115, the output of which is fed to a parallel pair of oppositely-poled biased diodes 125, 126, acting as adjustable voltage limiters for both positive and negative voltages. The limited output is fed to the grid of a valve 141 which has its anode connected to an integrating network 150, 151 the integrated voltage across the condenser 151 being applied to the phase modulator. The differentiating network is designed to give increasing signal output up to about 3000 cycles as represented by the curve a of Fig. 7, and the integrating circuit to give decreasing output from about 50 cycles upwards, as shown by curve b. The joint effect is a flat response c between the frequency limits 50-3000. Audio components which, owing to' their amplitude and frequency, exceed the amplitude limits permitted by the diodes 125, 126 are reduced to these limits so as to avoid excessive frequency-deviation in the phase-modulated carrier wave.

Abstract: 430,396. Tempering glass. MEER, R., 35, Rue Marbeuf, Paris. Oct. 25, 1934, No. 30662. Convention date, May 24. [Class 56] [See also Group II] Relates to the method of temper ing plates or sheets of glass or metal ir which the sheets are cooled by jets of gas The invention con. sists in the combination, in one and the same apparatus, of means for causing the incidence of the jets of gas on the sheets to vary, and of means for producing relative movement between the jets as a whole and the sheet that is being tempered. The apparatus comprises two rows of tubes 1 which are journalled at one end in a plate 3 and at the other end in a casing connected to an air compressor. Orifices 5 are formed in the tubes, and channel members 7 cover part of the surface of the tubes in such a way as to prevent air from escaping from the orifices when they are not directed towards the glass plate 6. Gear wheels secured to the ends of the tubes mesh with one another, and the lower wheels mesh with a pinion 9 which engages a bevel pinion 11 on a crank shaft 12. The whole frame is supported by bearings 13 on two crank shafts 12 which rotate in unison with one another. Thus, when the shafts 12 rotate, the tubes 1 rotate on their axes so that the jets of air from the orifices 5 sweep over the surface of the sheet 6. At the same time, the whole of the tubes are moved with a gyrating movement parallel with the surfaces of the sheet. The tubes may be arranged to oscillate, instead of rotate, on their axes.
