  • Patent number: 5342576
    Abstract: The invention provides a magnesium manganese alloy suitable for use in the production of a pellet 10 for administration to a ruminant by dposition in its rumenoreticular sac. A typical pellet 10 comprises a magnesium alloy tube 12 enclosing a degradable core formed of plurality of tablets 14, 16. The magnesium alloy used in the construction comprises at least 90% by weight of magnesium, uyp to 1% zinc and up to 2% of manganese. Preferably the alloy may further include aluminium, silicon or zirconium along with iron and beryllium. When deposited in an animal's rumen the alloy reacts with the rumen juices to form an anodic film over the exposed surface of the tube 12. This prevents corrosion or dissolution of the tube 12 except at its exposed ends where galvanic corrosion by coupling with the electrically conductive core 14, 16 is provided. The normal requirement of a non-degradable exterior coating e.g. resin for the tube exterior is obviated.

  • Patent number: 4658392
    Abstract: An optically readable, high storage density information carrier usually in the form of a disk, for example, a digitally recorded audio disk (CD) or a video disk (VLP) including a base, and a microstructure on the base which contains the recorded information, and consists of spiral or annular tracks or channels on one or both sides thereof. A reflective layer of a suitable metal or alloy is applied to the side of the information disk carrying the microstructure in at least that portion in which the microstructure exists. The present invention provides an improved reflective layer which, in turn, is covered by a protective layer. The improved reflective layer is a metal alloy selected from one of the following groups of alloys: (1) a Cu-Cr alloy containing from 0.3 to 1.5% chromium, (2) an Al-Mg-Si alloy containing 0.5 to 1.5% each of magnesium and silicon, and (3) an Mg-Mn-Si alloy containing 1.2 to 2% manganese and 0.05 to 0.1% silicon.
