Patent GB-486755-A (GB)
Title: Process for the preparation of cellulose esters
IPC: C08B1/02
Filed: 1936-08-29
Abstract: Cellulose material is subjected, prior to esterification, to the action of a fatty acid, except formic acid, in vapour form in a chamber maintained at a temperature at or above the boiling point of the fatty acid in order to render soluble impurities such as lignin, fats, wax, resin, pentasanes, hemicellulose, and pectins, and the material is then subjected to an extraction treatment, e.g. with a solution of an acid, so as to remove the soluble impurities.  The pretreatment is effected in a chamber maintained at a temperature equal to or higher than the boiling point of the fatty acid employed. Chorinated fatty acids may be used.  In an example, acetic acid vapour is circulated through a chamber containing sulphite cellulose. The chamber is provided with internal or external heating means in order to prevent condensation of the vapours.  The treated material is then subjected to extraction with acid in liquid form in order to remove soluble impurities.  The material is then treated with acetic anhydride and sulphuric acid, a solution of cellulose acetate being formed.  Instead of acetic acid vapour, a mixture of acetic acid and dichloracetic acid vapour may be used.  Reference has been directed by the Comptroller to Specifications 263,938 and 264,937, [both in Class 2 (ii)], and 414,461.

Title: Recording spectral flame photometer apparatus
IPC: G01N21/72
Filed: 1962-06-25
Abstract: 963,030. Photo-electric spectrophotometers. TECHNICON INSTRUMENTS CORPORATION. June 25, 1962 [July 3, 1961], No. 24285/62. Heading G1A. A recording flame spectrophotometer for the analysis of a liquid containing a test substance and a reference substance as constituents, comprises a spectral-flame burner 12 a recorder 14 and a null type balance current ratio system 16 including a photosensitive device 18 for receiving the spectral light corresponding to said test substance to provide a first current and another photosensitive device 20 for receiving the spectral light corresponding to the said reference substance to provide a second current the recorder being operable by the current ratio system in response to the ratios of the said first and second currents, characterized in that the circuit of one of the photosensitive devices includes means to nullify the effect of false peaks and depressions in the said currents which would cause corresponding peaks and depressions in the record made by the recorder. In the embodiment shown a filter 22 in the path of light from the flame F to the photosensitive device 18 passes only light corresponding to the spectral line of the test substance and a further filter 24 allows only light corresponding to the spectral line of the reference substance to reach the device 20. The devices 18 and 20 are preferably cadmium sulphide cells and are connected to thermistors 52 and 54 respectively to compensate for ambient temperature variations. Variations in the current flowing in a circuit comprising the cell 18 thermistor 52 resistors 28 and 44 and a D.C. source 26, caused by changes in the resistance of the cell 18 cause a voltage drop across the resistance 42 and this is tapped at 44 to give a voltage at a D.C. /A.C. voltage converter 70, and similarly, changes in the resistance of the cell 20 cause a voltage drop across a resistor 46 part of which is tapped by a tap 60 linked to the stylus 40 of the recorder 14, the tapped voltage also being fed to the converter 70. The voltage difference at taps 44 and 60 is converted to an A.C. value by the converter 70, applied through a transformer 74 to an amplifier 76, the output of which is connected to one winding 78 of a twophase motor 66 the other winding 80 being fed from A.C. source 82, and causes the rotor of the motor 66 to rotate a shaft 64 and thus move a nut 62 carrying the stylus 40 and the tap 60 until a null balance of the voltages at the taps 44 and 60 is obtained, movement of the stylus 40 making a record on the chart of the recorder representative of the concentration of the substance in the liquid. To eliminate false peaks and depressions in the currents flowing in the circuits of the cells 18 and 20 due to the effect of noise from the flame F a capacitor 30 and a variable capacitor 34 are provided in the circuits as shown and initially the capacitor 34 is adjusted until the ratios of the peak to peak values to the average D.C. values of the currents flowing in the circuits are equal. Specification 963,029 is referred to.
