Vol 4. Moscow- Leningrad, Mashgiz, 1957, pp 138-144 ABSTRACT: An experimental investigation is made of the variation in the vibration frequency of hydraulic -turbine blades as a function of the density and viscosity of the fluid medium in which the vibra- tions occur. Thus, a blade's vibration frequency in water is 20-40c@o lower than its vibration frequency in air. The more rigid a blade is, the smaller will be its drop in vibration fre- quency. Altering the speed of the water flow from 0 to 3 meters per second has virtually no effect on the vibration frequency. 1. Turbine blades--Vibration V. A.

Pribory i tekhnika eksperimenta, 1960, No.5, PP-41-45 TEXT: A description is given of a high-sensitivity magneto- meter designed for measurements of variations in the Earth's magnetic field. A photograph of the apparatus is shown in Fig.l. In distinction to the forced precession which is observed when constant and radio-frequency magnetic fields are applied to a specimen, the "free precession" is defined as the precession of the macroscopic nuclear magnetization vector in a constant magnetic field, i.e. without the radio-frequency field, In the equilibrium state, the magnetization M =X 0H of the nuclear paramagnetic is parallel to the applied constant field H and in order to obtain a precession of the magnetization vector, the latter must be artificially given a non-equilibrium orientation in the field H. In the Packard-Varian method (Ref.1) this is achieved by preliminary magnetization of the specimen by a large magnetic field H in a direction which is roughly perpendicular to the measured deld H. Card 1/6 85340 S/12o/60/000/005/008/051 E032/E5i4 A Nuclear Magnetometer After the application of the auxiliary field the magnetization of the specimen increases in accordance with the law M = MOE, - exp(-t/T I )] I where M 0 = -k0Hp is the equilibrium magnetization. The time constant T 1 is called the thermal relaxation time and depends on the temperature and composition of the substance. For water Ti,--o3 sec (Ref.2). When the auxiliary field is switched off sdfficiently rapidly, the magnetization vector is incapable of changing its magnitude and orientation in space and begins to precess around the measured field H. The precession frequency WL is proportional to the magnitude of the measured field so that WL = yH, where y is a constant independent of the external conditions and is practically equal to the gyromagnetic ratio of the nucleus, measured in strong fields. Only for very weak fields, of the order of the width of the nuclear resonance line, does the constant y begin to depend on the field and temperature. The Card 2/6 85340 S/12o/60/000/005/008/051 E032/E514 A Nuclear Magnetometer variable magnetic flux associated with the precession of the magnet- ization vector induces in the coil surrounding the specimen an alternating e.m.f. of frequency W L. Thus, in order to measure the field strength, it is sufficient to mea.sure the frequency of this e'mf. Hydrogen nuclei are convenient as the probe element since they have the maximum gyromagnetic ratio (except for tritium) and this gyromagnetic ratio is accurately knoim. The magnitude of the precessing magnetization vector will decrease with time owing to relaxation processes and this reduction can be described by the formula L4 = X,[!!pexP( 2 After a few TA the precession effect becomes unobservable and in 2 the case of repeated measurements of H the precession must be periodically re-introduced. The block diagram of the magnetometer based on this effect, which was developed by the present authors, is shown in Fig-3. It consists of the probe, a commutator, a pre-amplifier, a time relay, a frequency meter and a supply block. Card 3/6 8534o S/12o/60/000/005/oo8/051 E032/E514 A Nuclear Magnetometer The probe is designed to have a sensitivity of about 2 x 10 -6 Oe with a pass-band of 100 cps and has a single coil which is used both to produce the auxiliary field H and to pick up the precession signal. The coil has 900 turns and is wound on a thin- walled perspex cylinder 12 cm long and 9 cm in diameter. The cylinder is filled with distilled water. The relaxation time of the specimen T 1 was determined from the dependence of the initial signal amplitude on the time of magnetization. The transverse relaxation time T (Ref.9) was determined from the rate of decay of the signal. Wiihin the limits of experimental error it was found that T1 = T2 = 2 sec. The relaxation time was reduced to 0.7 see by the addition of copper sulphate to the water. This corresponds to a time of measurement T m = 0.5 sec and time of magnetization T = 1 see. During the reception of the precession signal the coil @s tuned to the expect ed frequency with the aid of a capactor. With a single,fixed tuningthe probe can be used to uF: measure the Earth's magnetic field tn an interval,,0.017 Oe. In addition, the tuning can be altered so that other intervals can Card 4/6 85340 S/120/60/000/005/008/051 E032/E514 A Nuclear Magnetometer be investigated. The commutator is set up on a separate panel and is used in a periodic switch over of the probe coil from the magnetizing battery to the amplifier and vice versa. The commutator consists of a power and a signal relay controlled with the aid of a time relay. The power relay controls the magnetizing current and the signal relay shunts the coil with a 39 kJQ resistor and shorts the input of the amplifier. The power relay is switched off after a time T and a transint process takes place ir the coil with a time conJant of 2 x 10- . After a delay of 5 msec when the transient process has been damped out, the signal relay is switched off, opens the input of the amplifier and switches the probe coil to the amplifier input. The pre-amplifier has three stages consisting of 6)Kltj (k@ @P ubes. The amplification factor is 1500 and the noise factor l.'2. The design of the frequency me er is based on the requirement that with a sensitivity of 2 x 10 Oe the magnetometer should reliably measure precession frequency changes of 0*01 cps during the chosen time of measurement T M=0-5 sec. In order to ensure this accuracy in the measurement of frequency, use was made of the method described by Waters and Francis (Ref.13).
