Abstract: A hydrogen suppressing, flameless, heat generating chemical composition including magnesium or a magnesium-containing alloy, a hydrogen suppressor or eliminator, particulate carbon, a metallic salt including a cation and an anion and water. The anion is selected from the group consisting of silicate, carbonate, bicarbonate, phosphate, borate, perborate, percarbonate, perphosphate, persulfate, nitrate, nitrite, ferrate, permanganate, and stannate and combinations thereof. The magnesium or magnesium-containing alloy, hydrogen suppressor or eliminator, particulate carbon, metallic salt and water are each present in a proportional amount to generate sufficient heat to heat water, medical supplies and/or consumable rations.

Abstract: The present invention relates to flameless heating apparatus for food products. In particular, the present invention relates to an improved potentially exothermic mixture/blend for such heaters and to a meal package including foods, and heating apparatus. It is known to have food products such as rations for back-packer, adventurers and military forces which comprise hermetically sealed packages of food which can be heated without flame, on demand. Such food products and apparatus are collectively referred to as Meals-Ready-to-Eat (“MRE”). In addition to the above uses, the products can be used as emergency rations for shelters and for heating of non-food products. Currently MRE packages yield hydrogen as a by-product. The present invention seeks to improve the efficiency of the reaction. In accordance with the present invention, there is provided a composition operable to provide thermal output with no or an insignificant production of any flammable gasses.

Abstract: A heating apparatus includes an elongated flexible envelope (4) comprising two sheets (6), (8) that are attached to each other along permanent side seams (10), (12) and along a permanent bottom seam (14) and a moisture-activated chemical heater (16) disposed inside envelope (4), wherein envelope (4) is folded over on itself and secured by temporary side seams (18), (20) and a permanent top seam (22) to form a continuous moisture barrier surrounding the moisture activated chemical heater (16) and wherein heater (2) may be opened for use by removing top seam (22) and unfolding envelope (4) by unpeeling temporary seals (18), (20) to provide unfolded envelope (4), wherein sheets (6) and (8) remain sealed along permanent seams (10), (12) and (14), but wherein envelope (4) now has an open top end (30).

Abstract: This invention is in the field of expandable, exothermic gel-forming compositions that are predominately useful in the consumer products and medical industries. More particularly, it relates to the use of expandable particulate exothermic gel-forming compositions with efficient and long-lasting heat production for heating surfaces and objects without the need for electricity or combustible fuel.

Abstract: A fuel for splitting water into hydrogen and an oxide component comprises a substantially solid pellet formed from a solid-like mixture of a solid-state source material capable of oxidizing in water to form hydrogen and a passivation surface layer of the oxide component, and a passivation preventing agent that is substantially inert to water in an effective amount to prevent passivation of the solid-state material during oxidation. The pellets are brought into contact with an alloy of the passivation preventing agent having a melting point temperature below that of the solid-like mixture to initiate the hydrogen-producing reaction at a lower temperature.

Abstract: A hydrogen suppressing, flameless, heat generating chemical composition including magnesium, a hydrogen suppressor or eliminator, particulate carbon, an alloying metal selected from the group consisting of: iron, cobalt, nickel, zinc, aluminum and mixtures thereof, a metallic salt including a cation and an anion, wherein the anion is selected from the group consisting of silicate, carbonate, bicarbonate, phosphate, borate, perborate, percarbonate, perphosphate, persulfate, nitrate, nitrite, ferrate, permanganate, and stannate and combinations thereof, and water. The magnesium or magnesium-containing alloy, hydrogen suppressor or eliminator, particulate carbon, alloying metal, metallic salt and water are each present in a proportional amount to generate sufficient heat to heat water, medical supplies and/or consumable rations.

Abstract: Less hazardous methods for generating thermal energy for heating water, medical supplies or comestible products using improved flameless chemical heaters/flameless ration heaters by novel chemical or electrochemical means, each capable of suppressing the generation of hydrogen gas. Remote unit self-heating meals may be more rapidly heated by forming a reaction mixture comprising magnesium or a magnesium-containing alloy, and a hydrogen eliminator or suppressor, and introducing water to react the reaction mixture and generate a more rapid release of thermal energy sufficient to effectuate a more accelerated temperature rise and more rapid heating of medical supplies, water, rations or other comestible substances while simultaneously suppressing or eliminating the generation of potentially hazardous hydrogen.

Abstract: The present invention is a package for selectively heating or cooling a food product of the package utilizing a temperature-changing pack disposed within an inner container. The temperature-changing pack is formed in a manner which prevents the inadvertent or premature mixing of the chemical reagents to initiate the heating or cooling reaction. Further, the temperature-changing pack is positioned within the inner container at a location where the food product comes into contact with the pack on multiple sides to maximize the heat transfer between pack and the food product. The inner container can be positioned within a reusable outer sleeve that insulates the inner container to further maximize the heat transfer between the pack and the food product.
