Title: Process of preparing cellulose butyrate
IPC: C08B3/08
Filed: 1921-03-09
Abstract: Before esterification, the cellulose is treated with a catalyst such as sulphuric acid, in the presence of acetic acid; a suitable mixture consists of 1-5 per cent of sulphuric acid, 5-8 per cent of water, and the remainder acetic acid.  After thorough impregnation, the excess of the solution is removed, and the cellulose is then treated with a mixture of butyric anhydride and butyric acid, and the esterification continued until a sample shows the desired solubility; if the preliminary solution contained only a low percentage of catalyst it is advisable to add a further proportion to the butyrating mixture after a sample shows good solubility in chloroform, and then to allow the reaction to proceed until solubility in benzol and alcohol is obtained.  The butyrate is soluble in chloroform, acetylene tetrachloride, acetone, ethyl acetate, phenol, hot alcohol, hot benzol and solvent naphtha, alcohol-benzol, and alcohol-carbon tetrachloride.

Abstract: 1,096,448. Measuring blood flow. SOCIETE NATIONALE DES PETROLES D'AQUITAINE and J. ESPAGNO. Feb. 22, 1966 [Feb. 22, 1965; Sept. 28, 1965 (2)], No. 7801/66. Heading A5K. [Also in Division G1] Blood flow in an organ is measured by injecting a radio active tracer into the organ and monitoring the decrease in radioactivity of the organ with time. An isotope with a half life of several days, such as Xe133, is used. The output pulses from scintillation counter 1, 2 detecting the radioactivity are counted in a counter 6 for successive equal intervals of time and each count is applied in turn to a memory 8a. The contents of memory 8a are converted to analogue form by a converter 8b and logarithm thereof is produced by the diode 9a. The rate of change of this logarithm, which is the logarithmic decrement of the radioactivity and consequently indicative of the rate of blood flow, is derived by a differentiating circuit 10, 11 and displayed on an indicator 12. The circuit 13 is provided to control the length of the counting intervals so that the counter 6 is substantially filled in the first counting interval. A quick rough indication of the rate of decline of radioactivity in the organ is provided by circuit 14 by determining the time taken for the memory content to fall from one predetermined value to another.

Filed: 1944-05-09
Abstract: 632,356. Aerials. POLYDOROFF, W. J. May 9, 1944, No. 7923. [Class 40 (vii)] Two rotatable loop aerials wound on iron-dust cores are provided for use at low and high radio frequencies respectively, and the disconnected lower-frequency coil is prevented from interfering with the higherfrequency coil when the latter is in use. In the embodiment shown in Fig. 1, a coil 12 having relatively large inductance for use at low radio frequencies is mounted at right angles to a coil 13 having relatively small inductance for use at high radio frequencies. The coils are geared to a shaft 47 so that they may be rotated while remaining at right angles to one another, split gears being preferably used to eliminate backlash. One or other of the coils is selectively connected to a direction-finding receiver through the cable 42, and the idle coil being at right angles to the active coil does not absorb energy from it or set up deviation errors. The coils are mounted on a base 32 attached to the fuselage 10 of an airplane and the shaft 46 of the rotary gear engages the external controlling shaft 47. A streamlined. shield 22 is attached to the base 32 and in order that coil 13 may be temporarily aligned with coil 12 to permit of assembly, coil 13 can be decoupled from its shaft 29 by loosening the grub-screw 51, which is accessible through a hole in the base 32, Fig. 2 (not shown). The coils may be wound to eliminate displacement currents as described in Specification 632,355. In a modification, Fig. 3, the coil 65 with large inductance and coil 68 with small inductance are wound on a single former 61 with hollow iron-dust core 60 and each is wound in two halves whose inside ends are connected in the manner described in Specification 632,355, external connections being made through sliprings and brushes 77.. When the higherfrequency coil 68 is in use the lower-frequency coil 65 is shunted upon it, for direction-finding at high frequencies, in order that the lowerfrequency coil may not wastefully absorb energy or cause deviation errors. The requisite connections are made by means of a switch 84 or a remote-controlled relay, Fig. 4 (not shown). The loop earth is connected to the sheath of the cable 92 through the centre slip-ring. The coils are screened against the electric vector of radiation by cloth woven with parallel wires 101, Fig. 5, and separated from the windings by an insulating tube, the wires being open-circuited along the top of the coil and grounded at the bottom. Discs containing similar wires arranged vertically are provided at the ends of the coil, Fig. 6 (not shown). Alternatively the electrostatic screen may comprise copper or like foil. The screening arrangements constitute the subject-matter of Specification 632,422.
