Title: Control of hole measurement
IPC: G01B11/08
Filed: 1975-01-23
Abstract: 1465231 Measuring dimensions photoelectrically EASTMAN KODAK CO 23 Jan 1975 [23 Jan 1974] 2976/75 Addition to 1461700 Heading G1A In the method and apparatus for measuring the length and diameter of a capillary in a spinneret as claimed in Specification 1461700 in order to compensate for errors due to the capillaries being not exactly in a circle, or the centre of the spinneret not being coincident with that of the circle of capillaries, resulting in a capillary not being correctly aligned with the laser beams as it is moved into the examination zone, the spinneret as a whole is translated in a radial direction , so as to obtain measurement signals which during the scanning of a particular capillary relate to correctly centred beams. The apparatus includes a generator 31, 32 producing the signals B for the oscillation of shaft 20 carrying scanning prisms 13, 14. This signal B or a delayed form of it, D, obtained via delay circuit 41, is applied to sampling circuit 40 to develop the error signal J for servomotor 50 used in driving the carriage carrying the spinneret by the required amount. The periodic sampling signal I, which controls the circuit 40 and determines the level of the signal J during each oscillation of shaft 20, is developed by operating on a signal C which comprises the ratio signal I o I R1 , the output of detector 18 divided by the output of the corresponding reference beam, and effectively represents the position of a capillary relative to the examination zone. The signal I is derived from signal C by a series of differentiation and pulse squaring operations, followed by rectification in circuits 35-39. Extraneous triggering of servomotor 50 is prevented by the loop including integrator 55.

Title: Inverter system
IPC: H02M7/62
Filed: 1951-02-07
Abstract: 682,653. Converting. BRISTOL'S INSTRUMENT CO., Ltd. Feb. 7, 1951, No. 3032/51. Class 38 (ii). In a measuring or other circuit including an inverter for deriving an A.C. proportional to a D.C., the effect of lack of symmetry in operation of the moving contacts 18 of the inverter 10 is eliminated by a further contactor 40 with contacts 44, 45 operating at twice the frequency of and in series with the contacts 18. When a unidirectional voltage at 29 is inverted to alternating voltage across transformer winding 33 by the co-operation of moving contact 18 and fixed contacts 21, 22 of vibratory converter 10 energized from an A.C. supply 17, and contacts 44, 45 remain closed, the alternating voltage has the form A or B, Fig. 3, according as the times during which contact 18 engages contacts 21, 22 are of equal or different durations, but both are of fundamental frequency based on the D.C. output. If the input D.C. has an A.C. component of fundamental frequency, the output voltage has components C or D, Fig. 3, whether the contacts operate symmetrically or not. In the latter case, it may be seen from D that the output has an alternating component of fundamental frequency based on the input component resulting from the asymmetry between successive half-waves whereby errors are introduced. To remove this asymmetry, contacts 44, 45 of the unpolarized vibrator 40 driven from and operating at twice the frequency of A.C. supply 17 are made to close for such a duration, and by means of phase-shift 46 at such a time, that they are closed for the central portions only of the half-cycles which are all similar, as shown, for rectified component E, Fig. 3, the asymmetrical portions being cut out. The contacts of further vibrator 40 may be in parallel with transformer winding 33 instead of in series, Fig. 2 (not shown). Specification 678,703 is referred to.

Title: Production of ethylene diamine
Filed: 1953-02-03
Abstract: In the production of ethylene diamine ethylene chloride is reacted with an aqueous solution of ammonia having a concentration above 35 per cent by weight.  The process is carried out at elevated temperature and in a closed system under pressure.  The process may be carried out continuously especially when that proportion of ethylene chloride which dissolves in the aqueous ammonia is used.  In an example a mixture of ammonia and water and ethylene chloride are pumped under pressure through a system of nickel pipes maintained at an elevated temperature.  Surplus ammonia is expelled from the reaction mixture in a pressure column.  Sodium hydroxide is added to the product after dilution with water, sodium chloride is separated and ethylene diamine hydrate and polyethylene polyamine are obtained on fractionation. Variations of reaction velocity with concentration of ammonia in the solutions employed and the solubilities of ethylene chloride in aqueous ammonia solutions of various strengths at various temperatures are recorded in Figs. 1-3 (not shown).
