Title: Improvements in and relating to the preparation of trichlorbenzenes from hexachlorcyclohexanes
IPC: C07C17/25
Filed: 1952-05-07
Abstract: A process for preparing trichlorobenzenes and hydrogen chloride, comprises heating a hexachlorcyclohexane to a temperature above 200 DEG  C. in the presence of a catalytic amount of a metal oxide or carbonate able to effect dehydrochlorination thereof, the liberated hydrogen chloride and the trichlorobenzene formed being discharged from the reaction vessel.  Suitable compounds are oxides of calcium, barium, aluminium, zinc, cadmium, strontium, chromium or manganese and carbonates of calcium or sodium.  About 5 per cent by weight based on the hexachlorocyclohexane is usually sufficient.  Preferably the reaction is carried out batchwise in the liquid phase.  The catalyst used is found almost unchanged in the sludge in the reaction vessel and may be re-used.  In an example a -hexachlorcyclohexane is heated with calcium oxide, hydrogen chloride and a mixture of trichlorbenzenes, primarily 1,2,4-trichlorobenzene being distilled off and condensed.  The reaction is completed at about 280 DEG  to 300 DEG  C.  Other isomers of hexachlorcyclohexane may be similarly reacted.ALSO:A process for preparing hydrogen chloride and trichlorbenzenes comprises heating a hexachlorcyclohexane to a temperature above 200 DEG C. in the presence of a catalytic amount of a metal oxide or carbonate able to effect dehydrochlorination thereof, the liberated hydrogen chloride and the trichlorbenzenes formed being discharged from the reaction vessel.

Title: Current limiting and voltage stabilising circuit arrangements
IPC: G05D23/24
Filed: 1975-03-20
Abstract: 1494259 D.C.-D.C. converters SIEMENS AG 20 March 1975 [10 April 1974] 11558/75 Heading H2F [Also in Division G3] A current limiting and voltage stabilizing circuit comprises a blocking oscillator formed by a switching transistor 1 and transformer 3 having a primary winding 2 and feedback winding 8. A resistor 17 is included in series with the main current path of switching transistor 1. Control of output voltage is achieved by means of a thyristor 14 connected in parallel with the series arrangement of the input electrodes of switching transistor 1 and resistor 17 and controlled in dependence on the output of a comparator 23, responsive to the difference between a reference voltage 27 and a voltage dependent on the output voltage and arranged to stabilize the voltage and to protect the circuit against over-current conditions. The voltage across feed-back winding 8 is rectified by diode 13 to provide operating voltage for thyristor 14 and by diode 20 to provide inverse bias for the gate. As described, pulses in the secondary 40 are rectified at 41 ... 44 so as to provide D.C. outputs at 45 ... 48. The input is derived from A.C. mains 57 via rectifier 65 and via terminals 4 and 16. Starting.-A mains frequency starting pulse is derived by diode 31 and pulse shaping components 32, 33 and fed to the base of switching transistor 1. Voltage stabilization and over-current protection.-A voltage dependent on the output voltage is induced in winding 5 and is rectified by diode 6 and compared by transistor 23 with a reference voltage across Zener diode 27. If this voltage is excessive, thyristor 14 is turned on so as to block the base circuit of switching transistor 1 for some cycles until started by the next mains frequency pulse. A similar action occurs in the event of over-current, since this causes an increase in voltage across resistor 17.

Title: An improved device for washing and after-treating bobbins of artificial silk by the stacking system
IPC: D01D10/04
Filed: 1932-04-22
Abstract: <PICT:0380395/IV/1> Bobbins of artificial silk arranged in column form are treated with liquids or gases which are passed under suction or pressure through the thread windings, deformable sealings provided in the interior of the bobbin column being forced in a radial direction against the margins of each pair of superposed bobbins so as to maintain fluidtight seals.  As shown in the Figure, bobbins 1 are stacked over the perforated pipe 3 fixed in the bottom 2 of a tank or carriage.  The perforated pipe supports the bobbins and serves for the supply or withdrawal of the washing liquid or other treatment fluid.  Lengths of soft rubber tubing 5 on the pipe 3 are held by caps 6 which leave the central portion of each length free. This free portion of each length is opposite the point where two bobbins abut.  The pipe 3 is not perforated over the parts covered by the rubber tubing.  Water or air under pressure is introduced through pipes 7, 8 to the inner surfaces of the free portions of the rubber tubes 5 causing them to bulge out and press against the edges of the bobbins.  Similar sealing devices are arranged at the top and bottom of the column where the screwed-on cover 10 and the clamping ring 9 take the place of abutting bobbins.  When the treatment is completed the valves 11, 12 are closed and the rubber sealings are caused to retract by opening the valve 13.  The bobbins are then removed and replaced by others.  The apparatus is suitable for washing, desulphurizing, bleaching, scrooping, oiling, dressing, dyeing, and drying.

Title: Process for producing polyhydroxy organic compounds
Filed: 1953-04-27
Abstract: Polyhydroxy organic compounds are produced by reacting water-soluble olefinic compounds with hydrogen peroxide in the presence of an unstable peracid-forming metal oxide hydroxylation catalyst at temperatures between 40 DEG  and 60 DEG  C. until the hydrogen peroxide is substantially completely consumed but hydroxylation of the olefinic compound is incomplete and then completing the hydroxylation at a temperature between 60 DEG  and 100 DEG  C. Examples of water-soluble olefinic compounds are olefinic alcohols, aldehydes, ketones and ethers and the water-soluble halo-substitution products of the olefinic alcohols, ethers, aldehydes and ketones having the halogen atom or atoms linked to non-olefinic carbon atoms. The preferred metal oxide hydroxylation catalysts are the oxides of tungsten, molybdenum or vanadium.  In the presence of hydrogen peroxide the oxides form unstable peracids.  The oxides can be added in the form of their acids, e.g. tungstic acid or molybdic acid.  In the examples: (a) allyl alcohol is treated with hydrogen peroxide in the presence of water and tungstic acid to give glycerine; (b) crotyl alcohol is treated similarly to give glyceraldehyde and (c) acrolein is treated with hydrogen peroxide in the presence of osmium tetroxide to give glyceraldehyde.
