Title: Improvements in and relating to the manufacture and production of organic esters of cellulose
IPC: C08B1/02
Filed: 1934-09-14
Abstract: In the production of cellulose acetate, cellulose material is treated for not less than 24 hours with a small proportion of acetic acid, i.e. not more than one part of acetic acid to one part of cellulose, at a raised temperature, while allowing little or no evaporation to take place, and then the mixture is heated under conditions such that acetic acid and water are evaporated off until the product contains less than 1 per cent of water.  The product which contains a small proportion of combined acetic acid may readily be further acetylated to form a cellulose acetate suitable for the production of artificial threads.  Glacial or fairly concentrated acetic acid is preferably employed.  The proportion of acetic acid used may be 30--40 per cent of the weight of the cellulose.  The process is carried out in the absence of a catalyst or in the presence of so little catalyst that no appreciable degradation is caused.  In an example, cotton linters containing 5--6 per cent of moisture are heated in a closed container with concentrated acetic acid at 65 DEG  C. for four days.  The material is then spread out and heated while passing a current of air through the vessel until the material contains less than 1 per cent of water.  The material contains 3 per cent of combined acetic acid. In another example, cotton linters are heated with 50 per cent strength acetic acid for five days, and then spread out and heated for a day until they contain less than 1 per cent of moisture.  The material may be further acetylated using 2 parts of acetic anhydride for each part of cellulosic material.

Title: Method and apparatus for storing and reading out impulse resonance spectral data
IPC: G06G7/19
Filed: 1970-06-03
Abstract: 1339076 Impulse resonance spectrometers VARIAN ASSOCIATES 19 April 1971 [4 March 1970] 26801/71 Heading G1N In an impulse resonance spectrometer in which the resonance signal is analyzed into its Fourier components, a substantially pure absorption or dispersion resonance output is obtained by analysing the Fourier components covering a reference resonance line to obtain an output representative of the line symmetry, and changing the phase of both the real and imaginary parts of the Fourier components by like amounts to reduce one to zero and maximize the other. In Fig.1, resonance signals from an impulse gyromagnetic resonance spectrometer 1 are accumulated in a time averaging computer 3. An arithmetic unit in the computer derives the Fourier components, the real parts of which are multiplied by a first very low frequency (#À1 Hz) sine wave at 6, and the imaginary parts of which are multiplied at 7 by a second sine wave of the same very low frequency in quadrature with the first. The outputs of the multipliers 6, 7 are added at 11, integrated at 12, and compared at 13 with a reference signal representing a zero level (for symmetry of a pure dispersion line) or the maximum level so far (for symmetry of a pure absorption line), the thus derived error signal controlling the phase of the oscillator 8. If this is done using the dispersion mode of the reference line and it is then desired to record the absorption spectrum, the phases of the sine waves fed to the multipliers 6 and 7 are interchanged. In a modification Fig.7 (not shown) the sine wave multiplication is performed digitally in the computer. In Fig.8, the Fourier components stored at 25 are read out under the control of a scanner 39 at a rate which may be slower than or faster than the rate of accumulation of data in the store. A local oscillator 33 and modulator 28 raise the frequency of the Fourier components to reduce the relative frequency range of the signals. The error signal output of the line symmetry comparator 13 may be used to control a variable time delay 35, or a phase shifter 36, or a variable time delay 38, or a phase shifter 37. The resonance spectrum analyzed may be nuclear magnetic resonance, electron spin resonance, nuclear quadrupole resonance, magnetic resonance of ferromagnetic materials, magnetic resonance of molecular beams, electrical resonance of molecular beams and ion cyclotron resonance. The line symmetry analysis may be done by comparing positive and negative peak amplitudes.
