Abstract: A hemodialysis apparatus that carries out hemodialysis treatment by measuring or calculating the blood volume or its volume change as a blood indication level, and by controlling dialysis conditions according to said target blood indication level, wherein the chronological course of said blood indication level is defined as a target control line, and the primary blood volume (BV0) can be calculated as blood indication level. In the former part of the dialysis operation, the water removal is controlled so that the circulating blood volume in the body approach to the standard blood volume (BV st) with the use of said target control line. After the water removal of the former part of the dialysis operation, when the circulating blood volume in the body attains the standard blood volume (BV st), the latter part of the dialysis operation is started. In said latter part of the dialysis operation, the water removal operation is performed by substantively maintaining said standard blood volume (BV st).

Abstract: Rifle (1) comprises barrel (2) and loading means (15) for introducing a projectile from magazine (7) into breech (4). The projectile is propelled by a compressed gas propellant initially stored as a liquid in canister (10). The liquid is heated to a super critical state in chamber (8) by heating element (12) to induce a phase change such that the liquid becomes a highly dense gas. The phase change from liquid to gas provides the energy required to expel the projectile at high velocity from rifle (1), regardless of the ambient temperature.  The propellant is preferably CO2 which is heated to 31.06 °°C.  Rifle (1) produces minimal noise and no heat signature, making it suitable for military and stealth purposes. A pistol and launchers for grenades or mortar bombs are also disclosed. Another version can launch low earth orbit satellites or payloads.

Abstract: The present invention consists of an improved method and apparatus to upgrade bitumen in various forms which comprises four main components; namely, a fractionator equipped with a condenser, a heavy gas oil catalytic treater, a catalyst regenerator/gasifier and a gas cleanup assembly. In operation, the bitumen in liquid form is fed to the fractionator for initial separation of fractions with the bulk of the bitumen leaving the bottom of the fractionator in the form of a heavy gas oil which is pumped to the catalytic treater and sprayed on a hot catalyst to crack the heavy gas oil (an endothermic reaction) to release lighter hydrocarbons in the form of H2 rich volatile matter while depositing carbon on the catalyst. The volatile matter from the treater is directed to the fractionator where the condensable fractions are separated from the non-condensable H2 rich gas, a valuable primary gas. The carbon containing catalyst from the treater is recycled to the regenerator/ gasifier, and the catalyst after being regenerated (an exothermic reaction) is fed hot to the treater. Various fractions are removed from the fractionator as intermediates in the form of light napthas and light oils. The off-gas from the regenerator/gasifier is directed to a gas cleanup system to produce a valuable secondary gas. Both the primary gas and the secondary gas may be further utilized in the processing of the intermediates produced by the method, the primary gas being a source of H2 and the secondary gas being a source of thermal energy.

Abstract: The present invention relates to a method of regulating and controlling surface temperature of concrete or asphalt structure (the structure) and the like, as well as atmospheric or air temperature over the structure by encapsulating and containing temperature (thermal) control materials (TCMs) or/and water in the structure which constructs or constitutes pavements, roofs, parking lots, walls and the like. Volume ratio of water and one or more TCMs encapsulated and contained in the structure are from 0% to 100%. Based on simulation analysis, on one hand, the present invention, in summertime, can reduce the highest temperature on surface of the structure by up to 56.5% (reduced by about 46°C), and reduce the highest temperature of air over the structure by up to 54.4% (reduced by about 48°C), therefore "heat island" effect in urban areas in summer can significantly be reduced, thus saving cooling energy and benefiting human health. On the other hand, in wintertime, by the invention the surface temperature of the structure can be raised by up to 5.6°C, and the temperature of air over the structure can be raised by up to 5°C, accordingly heating energy demand is reduced.
