Title: Improvements in and relating to measurements using sonic or ultrasonic mechanical oscillations
Inventor: RANKIN ALEXANDER BRYCE CALDER
IPC: G01N29/07
Filed: 1962-11-16
Abstract: 1,013,836. Ultrasonic testing. S. SMITH & SONS (ENGLAND) Ltd. Nov. 18, 1963 [Nov. 16, 1962], No. 43495/62. Heading H4D. A method of measuring the velocity of ultrasonic waves in a sample 10 (Fig. 1), or 22 (Figs. 4 and 5), having two parallel surfaces (e.g. 16 and 19, Fig. 1) or for measuring the distance between the surfaces when the velocity is known comprises transmitting pulses of ultrasonic waves from a transmit-receive transducer 12 through a fluid coupling medium and into the sample through the front face thereof (e.g. 16, Fig. 1), displaying on a cathode-ray tube (see Fig. 2) against a time-base triggered by the transmitted pulse 17, the pulse 18 due to the first reflection at surface 16, pulse 20 due to reflection at surface 19 and pulse 21 due to the second (or higher) order reflection between surface 16 and face 12 of the transducer, the distance d between 12 and 16 then being adjusted by means of the micrometer 13, 14 to bring pulses 20 and 21 into coincidence. The velocity C m  in the sample is then derived from the relationship C m  = xCL/d, where x is the distance between the faces of the sample and CL the velocity of ultrasonic waves in the fluid coupling medium. The latter (comprising, e.g. a mixture of ethylene glycol and water) is contained in the enclosures 11, 23 or 25 and in the case of 23 (Fig. 4) the sealing ring 24 may be dispensed with and the open end sealed with a thin plastic membrane and a coupling medium such as oil used between the under surface of the membrane and the upper face of the sample 22. Instead of triggering the display time-base by the transmitted pulse it may be triggered by the pulse 18 due to the first reflection of surface 16 (Fig. 3, not shown).

A combined oxygen jet and liquid fuel burner for use in metal treatment comprises a cylindrical body 10 terminating in a nozzle block 11 provided with a central convergentdivergent bore 12 and a plurality of orifices 15 around the central bore and a liquid fuel nozzle 25 adapted to be moved within the body 10 between a retracted position in which it is spaced from the nozzle block 11 to permit the flow of oxygen through the central bore 12 and in which the central bore of the liquid fuel nozzle itself is blocked by a resilient stop 28, and an advanced position in which the liquid fuel nozzle co-operates with the convergent portion of the central bore 12 of the nozzle block 11 to provide a narrow passage 41 through which oxygen passes to atomize the liquid fuel from the liquid fuel nozzle, movement of the liquid fuel nozzle operating means for closing the plurality of orifices 15 when the liquid fuel nozzle is retracted and opening them when it is advanced. The liquid fuel nozzle 25 is mounted on the end of a tube 18 threaded at 23 to the inner end of a fixed liquid fuel supply tube 21. The resilient stop 28 is disposed on the end of a spigot 27 on the end of the fixed tube 21. The means for closing the orifices 15 comprises an annular block 39 connected by springs 38 to an outer sleeve 35 threaded at 33 to an inner sleeve 32 connected to the tube 18. A pin 36 on the body 10 projects into a slot 37 in the outer sleeve 35 to prevent rotation of the latter. The threads 23, 33 are of the same hand but of differing pitch so that when the tube 18 is rotated to advance the liquid fuel nozzle 25 the outer sleeve 35 moves backward so that the annular block 39 opens the apertures 15. The movement is stopped by the end of the outer sleeve 35 abutting a flange 16 on the body 10. Oxygen is supplied to the body 10 by inlets 17 in the flange 16 and passes through passages 40 in the inner sleeve 32 to the orifices 15 and to the narrow passage 41 around the fuel nozzle 25. The body is cooled by a water jacket 42. The combined oxygen jet and burner may be used in an open hearth or an electric furnace or in melting small amounts of iron in a ladle or top blown converter.

Abstract: 1,011,303. Aerials. SIEMENS & HALSKE. Nov. 23, 1962 [Nov. 23, 1961], No. 44328/62. Heading H4A. Means are described of modifying a known aerial array, Fig. 1, comprising four half-wave dipole assemblies and 3 (the other two not being shown), fed with signals from a common source via individual feeders such that at a certain frequency the phase of the energy reaching the dipole assemblies advances by 90 degrees from one assembly to the next, whereby the aerial can operate over a frequency range of 0À85 fm to 1À15 fm, where fm is the geometric mean frequency without the minimum radiated energy in the horizontal plane falling below half the maximum value. In the arrangement of Fig. 3, dipole assembly 52 is fed with a feed line #m/4 shorter than that feeding dipole assembly   51, dipole assembly 53 is fed with a feed line the same length as that feeding assembly 51, but with the addition of a phase reversing unit, and dipole assembly 54 is fed with a feed line the same length as that feeding assembly 52, but with the addition of a phase reversing unit. By this arrangement, the phase difference between the energies at dipole asemblies 51 and 52, and between dipole assemblies 53 and 54, increases with increasing frequency, whilst that between dipole assemblies 52 and 53, and between dipole assemblies 54 and 51, decreases with increasing frequency. The four dipole assemblies are staggered along the side of the tower such that d<SP>1</SP>/d<SP>2</SP> = 1À15, and dipole assemblies 51 and 53   are turned through an angle α. The resulting horizontal lobe diagrams for f=fm, f = 85fm and f = 1.15fm are as shown at 60, 59 and 61, respectively. Alternatively, Fig. 2 (not shown), distance d 1  can be left equal to distance d 2 . Specification 1,011,304 is referred to.

Abstract: 950,690. Electric coils. AVCO CORPORATION. Dec. 14, 1961 [Dec. 30, 1960], No. 44765/61. Heading H1P. [Also in Division H2] In a magnetohydrodynamic generator, the transverse magnetic field is produced by a superconductive coil which surrounds the generator duct.  The superconductive coil comprises a number of layers 31 of conductors 32 on annular metal shells 33 which have axial cooling passages 34. A coolant, e.g. helium, is passed into the coil assembly via inlet 4 along passages 34 and exhausts via outlet 42 to keep the coil in a superconductive state. Sodium conductors cast into stainless steel tubing and insulated by oxidation or by painting the sides of the conductor not in contact with the coolant with an insulating material may be used. Methods of baffling the flow of coolant within the coil assembly to give optimum cooling are described The coil is wound to produce a magnetic field whose intensity decreases linearly along the duct in the direction of gas flow, Fig. 14 (not shown), and this reduces the effect of longitudinal Hall currents. The coil assembly may also be braced both internally and externally to prevent distortion, Figs. 12, 13 (not shown). Supply lead 62 to the coil is cooled by liquid nitrogen contained in chamber 62 and by the main coolant which surrounds it as it passes through chamber 25 to the coil, Fig. 9 (not shown).
