IPC: G01R33/24
Filed: 1966-12-06
Abstract: 1,173,298. Nuclear resonance magnetometers. TREASURE SALVORS Inc. Dec.6, 1966, No.54518/66. Heading G1N. In a proton precession magnetometer of the type in which a coil 201 round a proton sample 200 is used alternately for providing a polarizing field at an angle to the field to be measured and detecting the free precession of the protons after cessation of the polarizing field, a switch is provided for switching the coil between its "read" and "polarize" connections at a time when the mean magnetic moment of the precessing protons will be approximately aligned with the direction of the polarizing field. Thus, after several "polarize/ read" cycles, the polarization approaches that attainable with infinitely long application of the polarization field at the average polarization power in use. As shown in Fig.2, the output of the coil 201 during "read" periods passes through an amplifier 208 and limiter 209 whereby a square waveform 219 of constant amplitude and frequency equal to the Larmor frequency is fed through line 210 to frequency measuring circuits (not shown). Waveform 219 is also fed through a differentiating capacitor 211, a transformer and a diode 215 whereby a trigger pulse train 217 is fed to a multivibrator 202 so that at a time just prior to the self initiation of a new "polarization" period by the multivibrator due to its own free running time constants, a particular pulse in the pulse train 217 will trigger the multivibrator to cause relay 203 to operate switch 204. A phase adjust resistor 218 is provided. There is described with reference to Fig. 5 (not shown), a magnetometer which, in addition to the features shown in Fig.2, comprises a continuously running voltage controlled variable frequency oscillator (512) which is synchronized by a phase lock loop to be phase coherent with the precession signal at the start of each new "read" period. Thus a frequency measurement may be made at any time during the "polarization" periods as well as during the "read" periods and integration over several "polarize/read" cycles is possible.

An air matress having separately inflatable, interdigitated chambers 11, 12 is inflated in a controlled cycle by a control apparatus including a pneumatically driven rotary valve 5, 6 which is operated such that the chambers 11, 12 are alternately inflated and vented to atmosphere but with the provision that neither chamber is vented until the other has been inflated. The air supply 1 is delivered through a pressure regulator 2 to a pressure chamber 3 fitted at one end with the valve 5, 6 which comprises a stationary part 5 with ports 9, 10 and 17-20 and a rotary disc 6 with a semi-circular port 7 and a recess 8. The disc 6 is spring urged 23 into engagement with the stationary part 5 and is provided with a stem 21 having a cam slot 21a which co-operates with a follower block carried by a sleeve 22 which is reciprocated by a bellows 28 to rotate the disc 6. In operation, starting from the position shown in Fig. 1, one chamber 12 communicates through a duct 14 and ports 10, 7 with a pressure chamber 3 whilst the other chamber 11 is vented to atmosphere through ducts 13 and 15, port 17, recess 8 and port 19. Simultaneously, air is delivered through a duct 35 to a chamber 34 of the bellows 28 to move the partition 29 and hence the sleeve 22. Resultant rotation of the disc 6 causes both chambers 11, 12 to be put into communication with the pressure chamber 3 by means of the ports 9, 10 both communicating with the disc port 7. Simultaneously pressure is applied to the bellows chamber 32 to return the partition to its central position.. The valve disc 6 is correspondingly rotated to allow deflation of the mattress chamber 12 and of the bellows chamber 34. Resulting movement of the partition 29 causes pressure to be restored to both mattress chambers 11, 12. Further movement restores the starting situation of Fig. 1 with one mattress chamber 11 deflated.
