Abstract:
An evaporative cooling device (40) is disclosed for cooling water or other liquids comprising a vessel (50) adapted to receive water or another liquid, said vessel comprising a vessel wall (53, 54, 55), an outer layer (90) of absorbent material and a wick (85) extending through said vessel wall, such that said wick is positioned to contact said water or other liquid within the vessel and is adapted to transport a portion of said water or other liquid through the wall by capillary action to said absorbent material, said wick being substantially impermeable to gas or vapour, so that the cooling device (40) can be connected in-line in an hydration system of the kind comprising a reservoir (12) and a drinking tube (32). Water or other liquid transported from within the vessel to the outer layer by said wick is absorbed by the absorbent material, from which it evaporates, the latent heat required for such evaporation being removed from the water or other liquid disposed within the vessel as sensible heat through the vessel wall, thereby cooling such water or other liquid. In some embodiments, the cooling device (40) may be fan-assisted. Also disclosed is a cooling garment comprising a garment portion that is adapted to be worn by a user and an evaporative cooling device (40) for cooling water or other liquids that are circulated through integrant channels or tubes provided in the garment.
Abstract:
A protective undergarment (10), shown in the form of shorts, includes integrally formed protective panels (22, 26, 30) that exhibit slash-proof properties. The protective areas (22, 26, 30) are made from a flexible Kevlar® knit or the like, and extend to cover the groin, crotch, substantial areas of the buttocks and the inner thigh regions of both legs. The protective panels (22, 26, 30) are externally snitched to a low thermal burden material (18, 20), such as a polyester mesh, that provides elasticity and completes the structure of the shorts (10). The Kevlar® knit is flexible and preferably lies directly against the skin of a user to provide blast wave and ballistic fragment deflection while permitting mobility in a lightweight arrangement. Varying thickness of the Kevlar® knit can be used in the protective areas (22, 26, 30) selectively to enhance protection against blast wave and fragment penetration. The shorts (10) find particular application in battlefield theatres where military personnel are exposed to bomb threats.
Abstract:
Armoured over-trousers (10) are formed as “chinks” having an open lateral external flank (13). Protective anti-ballistic armour plate (42), integral with fabric material (22) used for the over-trousers or otherwise incorporated within correspondingly sized, shaped and strategically located pockets (40), protects lower abdominal regions, including the buttocks, upper thigh regions and genitals, of the wearer. The open flank (13) provides mobility whilst ensuring a low thermal burden and access to storage pockets in conventional trousers (14). The over-trousers are secured around the legs by strapping (16, 18) to reduce the possibility of a blast wave (36) funneling effect that might otherwise be experienced should the over-trousers (10) only fit loosely around the legs of a soldier.
Abstract:
Food products such as wraps (100) are displayed, sold and subsequently heated in a heating apparatus (200). Within the heating apparatus (200) are reactants, such as quicklime and water which, when mixed, generate steam. An individual steam nozzle extends within the interior of each wrap and is arranged such that the steam generated is injected into the food product within its outer wrapper. The outer wrapper therefore acts to form a steam container whereby efficient heating of each wrap is achieved. Generally, the outer wrapper acts as an insulator to enable the heated wrap (100) to be safely handled.

Abstract:
A steam generator device has a first and a second chamber, and walls mutually isolating the two chambers. Reagents which react together to generate steam when in mutual contact are mutually separated by a barrier, and disposed in the first chamber. An opening member forms a first opening between the chambers and a second opening through the barrier. Hence the reagents come into contact via said second opening, the reagents react thereby generating steam, and the steam flows through the first opening into the second chamber.
