  • Patent number: 6638429
    Abstract: Method and apparatus for processing a watery substance, such as sludge or manure, wherein in a mixer-drier (33) the watery substance to be processed, which may or may not be mechanically partly dewatered (in 31) and/or preheated (in 32), is mixed with zeolites of type A, which adsorb water from the watery substance while releasing adsorption heat which causes an amount of moisture to evaporate, while from the mixer-drier vapor and a mixture of zeolites and dried matter are discharged, whereafter the zeolites are regenerated in an oven (35) through heating, and are returned to the mixer-drier after being separated from dry matter residue formed by the heating, such as ash, and released moisture. Prior to the supply to the oven, at least a part of the dried matter can be extracted by a separation device (34) the mixture formed in the mixer-drier.

  • Patent number: 6623481
    Abstract: An electrosurgical probe including a metal cannula, partially provided with an electroinsulating coating, and filiform electrodes housed in the cannula in a stretched position. The filiform electrodes are provided with an elastic memory of an arched shape and as a result, come out from the cannula to occupy a limited, nearly spherical volume. The electrodes are fixed to the distal end of a control rod slidably arranged inside the cannula so that the electrodes in a stretched position are arranged side by side parallel with the control rod. The cannula includes a series of holes each positioned immediately under the free ends of the filiform electrodes and having a sufficient diameter for the passage of a respective one of the electrodes. The electrodes are removed from the cannula by pulling the control rod and retracted into the cannula by pushing the control rod.

  • Patent number: 6607768
    Abstract: Coffee beans and the like are roasted in an enclosed, pressurized roaster under conditions which provide rapid heat transfer and close control of roasting time-temperature profiles. The roasting chamber desirably has a bottom screen, a top screen and a shutter adapted to momentarily occlude flow through the various portions of the top screen. Roasting gas passes upwardly through the beans, entrains some of the beans and forces them against the top screen. The beans drop back into the chamber when the shutter occludes a particular portion of the top screen holding the beans. Time-temperature profiles can be controlled by monitoring process conditions such as inlet and outlet gas enthalpies.

  • Patent number: 6607668
    Abstract: Water purifier using membranes, ion exchange resins and electricity to remove ionic, organic and suspended impurities from water to produce high quality, pure water. Supply water is pre-treated by directing it first into a sediment pre-filter module, a softener module and a sediment removal and dechlorination module. The pre-treated water is supplied to a reverse osmosis module which separates the water into two streams (a purified water stream and a concentrate stream) by collecting fluids from both sides of pressurized membranes. The purified water is passed to an electrodeionization module which further purifies the water and directs the water to an ultraviolet sterilization module. The concentrate stream is divided into a recycle stream which is passed to the inlet of the reverse osmosis module and a waste concentrate stream which flows to an outlet of the machine. A control method for the water purifier is also disclosed.

  • Patent number: 6564458
    Abstract: A method of manufacturing radiators by joining a corrugated fin to a base plate, characterized by low costs and prevention of thermal deformation of the corrugated fin due to low-temperature soldering. A first soldering at the lower ends of the corrugated fin is conducted by a first soldering alloy in a recess heated by a heating plate in a mobile solder tank filled with the molten first soldering alloy. A second soldering alloy is heated by a heating plate on a base plate and the molten second soldering alloy is used to conduct a second soldering. When the corrugated fin is placed on the base plate, pressed and heated, the first and second solders are melted to join the corrugated fin to the base plate.
