Title: A process for producing fatty acids of vegetable or animal fats or oils from their glycerides
IPC: C11C1/04
Filed: 1937-03-08
Abstract: Fatty acids are obtained from fats or fatty oils by heating the fat with acid artificial resins, or distillation residues from acid artificial resins or colophony, which are free from volatile components, and thereafter recovering the fatty acids liberated by distillation.  Acid resins specified are, phenol-aldehyde condensation products with or without colophony, condensation products of colophony or abietic acid with formaldehyde, or of maleic acid with colophony, tung oil, terpenes or butadiene. Tallow; castor, olive, sardine, whale, poppyseed, or linseed oil; or nut oils may be treated.  The residues after removal of fatty acids are neutral resins which may be esterified with glycerine, which may be used in the manufacture of varnishes, or after heated with fatty oil, or with other artificial or natural resins.  The neutral resin or modified resin may be used in the manufacture of varnishes.  Example, a phenol-aldehyde-colophony condensation product of acid number 100 is heated with linseed oil in vacuo at 290 to 300 DEG  C.  Linseed oil acids of acid number 174 are distilled off preferably in vacuo with steam, leaving a resinous residue of acid number 11.ALSO:Neutral artificial resins are obtained by heating a fat or fatty oil with an acid artificial resin, and distilling off the fatty acids liberated preferably in vacuo.  Acid resins free from components volatile at the reaction temperature are used, for example; phenol-aldehyde condensation products, with or without colophony, condensation products of colophony or abietic acid with formaldehyde, or of maleic acid with colophony, tung oil, terpenes or butadiene.  Distillation residues of these or of colophony may also be used.  Fats and fatty oils specified are, nut oils, tallow, or castor, poppy seed, olive, sardine, whale or linseed oil.  Example, a phenol-aldehyde-colophony condensation product of acid number 100 is heated with linseed oil in vacuo at 290 to 300 DEG  C.  After removal of fatty acids, a resin esterified with glycerin of acid number 11 is obtained as residue. The resins may be further heated with fatty oils, artificial resins or colophony, to lower the melting point.

Abstract: 674,668. Centrifugal machines. WESTFALIA SEPARATOR AKT.-GES. March 20, 1950 [April 23, 1949], No. 6857/50. Class 23 In a method for the centrifugal separation and extraction of liquids by plant operating on the counter-current principle, the liquids are mixed in the stripping chambers of centrifugal separators connected in cascade. A separator for use in the above method comprises two stripping chambers 8, 9, and a stationary shaft 14 which extends beyond the centrifugal drum, is provided with supply and discharge channels and is surrounded by a stationary annular channel 27 extending into the upper stripping chamber 9, and serving as a supply passage for a liquid to be added to the mixture. The drum has a nest of plates 5, a distributer 4 and a separator plate 7. The shaft 14 has stripping discs 15, 16, for the light and heavy liquids respectively and a collar 19 to connect the channel within the shaft to the external feed and delivery lines. A solution such as phenolated water, which constitutes the heavy liquid and is shown in solid lines, is fed to the drum through a passage 20 together with a solvent such as butyl acetate which is shown in broken lines. The solution, less the phenol content yielded to the solvent, is discharged through the stripping disc 16 and a bore 26 together with a fresh supply of solvent fed thereto through a bore 27. The butyl acetate-phenol mixture is discharged through the disc 15 and a bore 25 together with phenolated water fed thereto through a bore 28. In a modification, the bores 27, 28 terminate at a point below the discs 16, 15, respectively, whilst the conduit 24 delivers to a point above the disc 16. Again, both liquids may be fed to the stripping chamber on the same side of the stripping discs.

Title: Apparatus for pulse hardening the surface of steel objects
IPC: H05B6/04
Filed: 1973-02-13
Abstract: 1380525 Automatic control of temperature IMPULSPHYSIK GmbH 13 Feb 1973 7063/73 Heading G3R [Also in Divisions C7, H2, and H3-H5] Apparatus for hardening the surface of a steel workpiece 20 by high frequency induction heating comprises an oscillator valve 3, a cavity resonator 1 and an inductor 17 coupled to the resonator by a loop 16. The radiation emitted by the heated workpiece is detected by a photo-diode 54 after passing through a selected orange, green or blue filter 53. The pulse produced by the diode in the  circuit 55, 56 is amplified and fed to the grid of a thyratron 59 thereby switching on the thyratron and controlling the output pulse width of the valve 3. A constant hardening temperature of the workpiece is therefore maintained since any increase or decrease of temperature above or below that determined by selection of the filter 53 causes a corresponding decrease of increase in the output pulse width of the valve 3 and consequently a decrease or increase in the heating of the workpiece.

Abstract: 1,171,272. Material for making coke. MARATHON OIL CO. 16 Feb., 1968, No. 7635/68. Heading C5E. [Also in Division C1] Coke for making graphite having a low coefficient of thermal expansion is made by a delayed coking process from a petroleumderived feedstock which comprises 85 to 100% b.w. aromatics and which contains less than 1% b.w. sulphur and less than 6% b.w. of an oxygen - containing compound. The process comprises pyrolysing the feedstock in the temperature range 1000‹ to 7000‹ F. at a pressure of at least 10 p.s.i.g. and separating the fraction boiling above 500‹ F. and delivering it to a heater where it is heated, with agitation, to from 900‹ to 975‹ F. for a time, e.g. 0À5 to 5 minutes, insufficient to form solids, and charging the residue from this step before it cools to 875‹ F. to a delayed coker. In the coker, the charge should not be allowed to cool below 700‹ F. in less than 30 minutes. In an example, the feedstock had a B.R. of 100‹ to 200‹ F., and was pyrolysed in the presence of steam for 0.5 second at 1500‹ F. and 15 p.s.i.g. A fraction initially boiling at about 700‹ F. was passed through the coil of a gas-fired furnace, such passage providing the necessary agitation. Initial cooling in the coker may be diminished by recycling condensed oil vapours from the coker through the heater and back to the coker. The coke may be crushed, calcined, recrushed and mixed with a coal tar or petroleum pitch shaped, prebaked and graphitized.
