Abstract: An improved method of purifying a fluid having fluid-borne contaminants I including the steps of: providing a pump (21) having an inlet (22) and an outlet (23); connecting the pump inlet to a source (24) of contaminated fluid; operating the pump at. a pressure ratio of at least 2.0 so as to sufficiently elevate the temperature of the fluid and contaminants passing through the pump, or, alternatively, operating the pump so that the outlet temperature of the fluid and contaminants passing therethrough is at least about 200° C.; and controlling the time during which the temperature of the fluid and contaminants are elevated; thereby to alter or convert substantially all of the contaminants passing through the pump.

Abstract: The invention relates to a walker having a main supporting frame, a superstructure frame and a body support means. The superstructure frame is operatively arranged for vertical adjustment relative to the main supporting frame and includes an adjustable interior opening for accommodating a user and an entrance gate operatively arranged to provide access to the adjustable interior opening. The body support means is secured to the superstructure frame and operatively arranged to support the user. Furthermore, the walker may include four wheels, each of which may include a directional locking apparatus and/or braking system, and the walker may include at least one arm support operatively arranged for supporting the user. The walker may also include at least one handle operatively arranged for transmission of the walker.

Abstract: The present invention relates to a body thermal regulation system. The system includes a fluid-circulating garment having a plurality of fluid-impervious compartments where each compartment is in contact with a different part of a body. At least one heating/cooling unit is positioned to heat and/or cool fluid circulating to the fluid-impervious compartments in the garment. The system also includes a fluid circulation system positioned to circulate fluid between the heating/cooling unit and the plurality of fluid-impervious compartments in the garment. The present invention also relates to a method for measuring heat fluxes in different parts of a body. The method involves providing to a subject the body thermal regulation system according to the present invention. Then, the temperatures and flow rates of fluid entering and exiting each of the plurality of fluid-impervious compartments in the garment are measured, allowing heat fluxes in different parts of the body to be determined.
