Title: Measuring the electrical resistivity of ground
IPC: G01R27/20
Filed: 1978-09-22
Abstract: In order to reduce the effect of any local inhomogeneity when measuring the electrical resistivity of ground, two measurements are made in different positions and an appropriately weighted average calculated. As described five electrodes are implanted in the ground at equal spacings along a straight line. An electrical current is passed through the ground between one pair of these electrodes and the potential difference between a further pair of the electrodes is measured. The electrode which is not used in this measurement is at one end of the line. A further measurement is then made with the four electrodes which exclude the electrode at the opposite end of the line. The measurements are combined to provide a measurement of apparent resistivity which is almost unaffected by a local resistivity variation.

Title: Purifying waste gases from nuclear reprocessing plants
IPC: B01D53/34
Filed: 1978-12-28
Abstract: In the purification of waste gases containing nitric oxides, iodine and iodine compounds and triturated water vapour from a nuclear reprocessing plant, hyper-azeotropic nitric acid is introduced at the head (6) of a counter-current gas/liquid contact column (4) and then conducted through a co-current contact column (1) where it is cooled to a temperature of up to -65 DEG C. Waste gas to be purified (22) is introduced into the head of column (1), and thence follows the path (23), (24) and (7). Organic iodine compounds and iodine are partially oxidised, in the cooler lower part of column (1), while in the warmer upper region of column (1) a proportion of the NO oxidised by the hyper-azeotropic nitric acid to NO2. NO2, iodine and water vapour are substantially absorbed by the hyper- azeotropic nitric acid during the subsequent passage through the counter-flow column (4). The flow ratio V=G/F of gas flow G and liquid flow F at any point of the counter-flow column is smaller than the iodine distribution coefficient D (G/F), (c, T), whereby c is the iodine concentration and T the temperature. <IMAGE>
Patent GB-790031-A (GB)
Abstract: 790,031. Gyroscopic apparatus. GENERAL ELECTRIC CO. Dec. 16, 1955 [Dec. 21, 1954], No. 36121/55. Addition to 777,021. Class 97(3) [Also in Group XXXVIII] Apparatus for automatically aligning a directional gyroscope 1, having a major axis 6 supporting gimbals 5 containing the minor axis 8 supporting the gyro rotor 7 on which is assembled a pin co-operating with stops 24 on the gimbal 5 to limit the tilt of the rotor 7, with a magnetic compass 2 comprises means for applying a torque to the major axis 6 until the pin engages the stops 24 so that the gyroscopic rigidity is removed, when a correspondence control system rotates the gyro until it agrees with the compass reading, and the major axis torque is then removed. The magnetic compass 2 comprises a saturable toroidal core 35 having an AC-energized winding with three taps 39. The orientation of the gimbal 5 about the main axis 6 is determined by stator windings 42, 43 fixed to the gyro frame, and a Z- shaped rotor 41 fixed to the gimbal 5. Winding 43 is connected to the taps 39 on the compass 2 and the' magnitude and direction of deviation between the gimbal direction and the direction of the earth's magnetic field is indicated by the phase and magnitude of the signal in winding 42, which is amplified at 44. Rotation of the rotor 7 about the minor axis 8 is detected by windings 19 mounted on the gimbal 5 and energized by leakage flux from the rotor 7, the tilt signal being amplified at 45. The alignment operation is initiated by pressing a spring-loaded switch button 46 which, at 49, closes the output circuit for amplifier 44 through relay winding 47, closing a holding circuit at 51, and energizing a motor 25 which, through gears 26, 27 and spring clutch 28, 29, drives an externally grooved cam 30 against a spring 31, thereby rotating and raising a cam follower 32 so that pinion 34 engages with gimbal gear 22 to rotate the gimbal 5 about the major axis 6, whereupon the rotor 7 precesses about the minor axis 8 until it is stopped by the peg 24. The gyroscopic rigidity is now absent, and the output signal of amplifier 44 causes the gimbal 5 to be rapidly brought into line with the compass 2, at which stage there is no input to amplifier 44 and therefore no output, motor 25 is de-energized and relay 47 falls, to connect at 55 the output from amplifier 45 to the motor 25, whereupon the gyro is precessed to remove the tilt from rotor 7, the input and output signals of amplifier 45 are also eliminated, and the system comes to rest with the gyro correctly aligned. For normal low-rate tilt precessing windings 19 may be connected to a low-torque motor on the major axis 6 comprising stator winding 17 and rotor 18. For low-rate directional precession winding 42 may be connected to a lowtorque motor comprising stator winding 20 and rotor 21. The compass 2 may be replaced by a manually operable heading selector. The system may be applied to set a gyro vertical into correspondence with two pendulums or other level-sensitive devices, producing signals indicating pitch and roll of the gyro frame.

Title: Method of Cooling a Reciprocating Continuous Casting Mould
IPC: B22D11/055
Filed: 1979-03-29
Abstract: In a method of cooling a reciprocating continuous casting mould for steel strands having side walls (2) with channels (3) flowed through by a cooling medium, the upper part of the side walls is less cooled than the rest, the cooling in the region of the side walls contacted by molten metal during reciprocation is retarded and thereby the maximum temperature in the mould is shifted in the upward direction by approximately the height of the reciprocating movement, and the surface temperature in the reciprocating region is kept constant. The cooling may be retarded by incorporating heaters 11, insulation spaces, or insulation materials into the mould wall. Defects in the strands are reduced. <IMAGE>

Title: Dipole mass laser-based gravity gradiometer
IPC: G01V7/10
Filed: 1979-05-10
Abstract: A gravity gradiometer uses at least one mass dipole 16 or 18 mounted in a laser force-measurement system to detect the torque on the mass dipole generated by gravity gradient. The mass dipole is mounted on one end of a photoelastic modulator element 12 positioned in the cavity 4, 6, 8, 10 of a ring laser tube 2 to differentially modulate circular polarization modes in response to application of a torque. In a preferred form, two mass dipoles are mounted on opposite ends of the modulator element which is rigidly supported at its center to improve noise rejection. A biasing element 32 may be provided to prevent phase locking of the laser, and the bias may be checked by a second ring laser wing the same cavity with a second laser tube 40. Beat frequencies indicative of the polarisation modulation are measured by photodetectors 40, 52. The differential modulation allows the apparatus to be used when moving, e.g. in a borehole. <IMAGE>

Title: Device for sensing the presence of contents at a certain level in a container
IPC: G01F23/296
Filed: 1980-07-01
Abstract: A device for sensing the presence or absence of contents in a container comprises a probe in the form of a rod 1 which projects through a seal 4 from a "dry" side of the device to the "wet" side of the device. An exciter 15 on the dry side is provided for exciting a first rod 2 which is mounted on the dry side and which is mechanically coupled to the probe rod 1 to cause the probe rod to vibrate. A detector 17 on the dry side detects the vibration in a third rod 3 which is mounted on the dry side and which is mechanically coupled to the probe rod 1. The first 2, probe 1 and third 3 rods have slightly different natural frequencies which are successively greater or less than one another such that when vibration of the probe rod 1 is undamped, in use, the three rods vibrate together but when the vibration of the probe rod 1 is damped, in use, by contents in the container, the third rod 3 is not forced to vibrate sufficiently by its coupling to the first rod 1 with as great an amplitude. Means are provided for discriminating between the response of the detector 17 to the amplitude of vibration of the third rod 3 when the vibration of the probe 1 is or is not damped by the contents and for providing a corresponding output signal. <IMAGE>
