Patent GB-1302731-A (GB)
IPC: G01S7/529
Filed: 1970-01-23
Abstract: 1302731 Acoustic attenuation comparison BIN-DICATOR CO 23 Jan 1970 [27 Jan 1969] 3353/70 Heading H4D Changes in the attenuation of an acoustic signal by a fluid material in a container are detected by transmitting an ultrasonic pulse through the container wall and across the container, receiving an echo of the pulse and detecting changes in the echo amplitude. The invention may be used for detecting the level of a liquid/liquid or liquid/air interface, or for comparative measurements of fluid viscosity or of the percent solid content of a suspension. In the Fig. 1 embodiment oscillator 11 pulses transducer 2 and the echo pulse from wall 10 or a reflector in container 1 passes through gate 14 (which is controlled to block signals at other times) and amplifier 17 to differential amplifier 19. The other input to amplifier 19 is a reference voltage derived by attenuating and delaying the oscillator 11 output. Attenuator 22 is set to balance the amplifier 19 inputs (a) when a fluid interface is at level A-A, whereby the polarity and magnitude of amplifier 19 output indicate (e.g. on a meter) the direction and extent of subsequent deviation of the interface from that level, (b) when a fluid interface is either above or below level A-A, whereby subsequent movement of the interface part A-A will cause relay 6 to energize a visual or audible alarm 7 and/or process control device 8, or (c) when a fluid or suspension in container 1 has a given viscosity or solids content value, whereby a meter at amplifier 19 output will register deviation of viscosity or solids content from that value.

Title: Improvements in or relating to the densifying of magnesia
IPC: C04B2/10
Filed: 1956-02-07
Abstract: Densified magnesia (periclase) is made by heating magnesia on a magnesium compound with a small amount of a lithium compound and firing the mixture.  Lithium halides are preferred but lithium carbonate, sulphate or nitrate may be used alone or in admixture with iron, chromium or aluminium in the form of lithium ferrite or chromate.  In examples, 0.01 to 1 per cent by weight lithium fluoride is mixed with finely powdered magnesia, magnesium hydrate, carbonate, or chloride and the mixture heated at about 1300-1400 DEG  C.  Most of the lithium salt is volatilized. Alternatively, the lithium salt is deposited from a salt solution as a coating on the magnesia, which may be in the form of a slurry; the mixture is then dried, briquetted and fired.  The product contains at least 95 per cent of magnesia and has a density of 3 to 3.5.  The densified magnesia may be ground and used as "grog" in the manufacture of refractory bricks.  U.S.A. Specifications 2,487,290, 2,641,529, 2,641,530 are referred to.
