Abstract: A heating device is provided comprising a heating chamber for receiving and storing a substance to be heated having at least two walls, a reaction chamber affixed to a wall of the heating chamber, a solid-state modified thermite reaction composition located within the reaction chamber and an actuatable trigger mechanism affixed to the reaction chamber such that the trigger mechanism is in contact with the reaction composition. According to another aspect, a heating device is provided comprising a heating chamber defining an interior space for receiving and storing a substance to be heated, a reaction chamber, a solid-state modified thermite reaction composition disposed within the reaction chamber such that it is physically isolated from and in thermal communication with the interior space of the heating chamber and an activator mechanism affixed to either reaction chamber or heating chamber such that the activator mechanism is in communication with the reaction composition.

Abstract: A high rate discharge battery cell 150 is disclosed. The battery cell 150 comprising an anode end 200 and a cathode end 100 contains: a laminate including at least one anode electrode sheet 102; at least one cathode electrode sheet 101; and at least one separator sheet disposed between the anode electrode sheet 102 and the cathode electrode sheet 101; wherein the anode electrode sheet 102 projects outwardly of the edge of the laminate towards the anode end 200 of the battery cell 300; the cathode electrode sheet 101 projects outwardly of the edge of the laminate towards the cathode end 100 of the battery cell 150; a first current collector 203 in electrical contact with the outwardly projecting part of the anode electrode sheet 102 in the laminate formed by metal spray; and a second current collector 103 in electrical contact with the outwardly projecting part of the cathode electrode sheet 101 in the laminate formed by metal spray.

Abstract: The present invention provides lubricant mixtures for use as base fluid in bearing grease comprising 25 to 90 percent w/w of a liquid ester having a viscosity at 40.degree. C. in the range 100 to 200 mm.sup.2 /s, and 75 to 10 percent w/w of a liquid poly-.alpha.-olefin having a viscosity at 100.degree. C. in the range 2 to 10 mm.sup.2 /s, and bearing grease compositions containing a major proportion of such lubricant mixtures, particularly such compositions containing a clay thickener.
