  • Magnesium anodisation methods
    Patent number: 7396446
    Abstract: This invention relates to a method of anodising magnesium material which includes anodising the magnesium while it is immersed in an aqueous electrolyte solution having a pH above 7, and in the presence of a phosphate, the electrolyte solution also containing a sequestering agent. The method may further include the provision of a plasma suppressing substance within the electrolyte solution. Furthermore, the electrolyte solution may also preferably include a tertiary amine such a TEA, and the current passed through the electrolyte solution may preferably be a straight DC current.

  • Multiple battery comprising a cranking battery and an auxiliary battery
    Patent number: 5866274
    Abstract: Batteries for boats and vehicles require a CRA (cranking) battery 23 and an AUX (auxiliaries) battery 22 to ensure a start. The preferred version has an AUX battery made of parallel plates and a CRA battery made of parallel plates lying in a monobloc case in face to face positions. Each battery has a pair of CRA terminals 20, 30 for the electric starter and a pair of AUX terminals 19, 31 for the AUX loads of the vehicle and the alternator. The AUX and CRA negative are joinable by a link or a switch 41 so that a single earth connection is made to the vehicle. Alternatives show the AUX and CRA batteries side by side, at 90 degrees, providing 24 v or 36 v with a 12 v tap; a CRA battery with two AUX batteries one 51 for constant voltage equipment. Advant-ageous disposition of terminals simplifies connections to vehicle wiring and to a like battery.
