Abstract: The invention relates to a method and apparatus for providing hydration fluids. The invention allows for a ‘background’ rate of providing a hydration fluid to be automatically supplied by an apparatus to a patient, for example intravenously, and for the patient to receive an extra amount of hydration fluid, or ‘bolus dose’, to be provided when the patient sends a signal to the apparatus. In preferred embodiments the background supply rate, the volume and rate of supply of the bolus dose and the maximum extra volume that can be provided as bolus doses in a given time can be set, for example, by a nurse.

Abstract: A fragment for an ordnance item having a blind recess within which are disposed a number of layers or pellets of thermite (Al-Fe.sub.2 O.sub.3) or a thermite-like metal-metal oxide mixture; the density of each layer being successively less than the layer beneath it, proceeding from bottom to top of the blind recess, due to the use of diminishing compacting pressures. The density of the top layer is such that it will ignite due to the heat and shock of explosive projection upon detonation of the ordnance item and produce the following reaction: 2Al + Fe.sub.2 O.sub.3 .fwdarw. Al.sub.2 O.sub.3 + 2Fe. Since the burning rate of the layers varies inversely with their density, a substantial portion of the thermite will remain unreacted over a considerable range until the fragment impacts with a target at which time the remaining chemical energy of the thermite will be explosively released.
