    摘要: A hardened cement is prepared by mixing together two slurries, one comprising water and a cement component and the other comprising water, beta anhydrite and calcium oxide and or calcium hydroxide. According to the invention the cement component of the first slurry comprises ferrite and C.sub.12 A.sub.7 or A.sub.7 A--CX.sub.2 (where X is a halogen atom) and a reactive source of silica.

    摘要: A fuel level probe has a series of stacked, annular capacitors, the capacitance of which changes with the dielectric constant of the fluid in which they are immersed. A multiplexer provides sequential measurement of each capacitor to determine a step change in capacitance and hence fluid levels based on the time at which the capacitance changes.

    摘要: A cement composition which when mixed with water hydrates to form a hardened cement containing ettringite comprises a high alumina cement, beta-anhydrite and calcium oxide and/or calcium hydroxide. The composition may also contain a calcium sulphate which is partially water soluble, an alkali metal sulphate, an accelerator for the high alumina cement such as lithium carbonate, and/or a bentonite clay. The composition is particularly suitable for filling cavities in mines.

    摘要: A substantially dry powder composition which when mixed with water forms a gel comprises a swelling clay, a sodium silicate having a silica to soda weight ratio of about 2.65:1 or below and an inorganic gelling agent for the sodium silicate which gelling agent does not introduce ions which significantly lower the gelling capacity of the clay.The composition is particularly suitable for use in coal mines as an anti-combustion material.
