  • Patent number: 6640462
    Abstract: Disclosed is a method of drying timbers loaded in a drying chamber, which comprises the steps of heating the drying chamber by a heating system up to a temperature of 80 to 100° C., subjecting the timbers to vacuum blowing by connecting the inside of the drying chamber with a vacuum chamber (receiver) evacuated by a rotary pump until the inside pressure of the drying chamber drops to 1 to 10 mmHg, disconnecting the inside of the drying chamber from the vacuum chamber, connecting the drying chamber with the atmosphere. When the inside of the drying chamber is connected with the vacuum chamber, the moisture content of the timbers is sharply reduced, so that their temperature sharply drops. Thereafter, when it is disconnected from the vacuum chamber, and connected with the atmosphere, the inside temperature of the drying chamber is again increased. Meanwhile, the heating system is worked during the whole process.

  • Patent number: 6637354
    Abstract: A process for recovering the byproducts of a process that burns coal and for reusing the byproducts is disclosed. The process includes the steps of identifying a disposal site that contains the byproducts (typically flyash and bottom ash), removing at least a portion of the byproducts from the disposal site, analyzing a sample of the portion of the byproducts to determine the loss on ignition of the portion of the byproducts, introducing the portion of the byproducts along with pulverized coal into a pulverized coal furnace if the portion of byproducts have a loss on ignition greater than or equal to a predetermined loss on ignition value (typically greater than or equal to 1 to 5%), and burning the portion of the byproducts in the furnace with the pulverized coal to render the byproducts into a commercially valuable fly ash and bottom ash having very low loss on ignition, typically lower than 3%.

  • Patent number: 6638245
    Abstract: This is a balloon catheter having at least two lumens. One of the lumens is a large working lumen. The balloon catheter is especially useful as a guide catheter or micro catheter and may be used in a variety of therapeutic and diagnostic procedures. In particular, it has value in treating neurovascular embolic strokes in combination with other devices which are delivered to the stroke site through that working lumen. The remainder of the lumens typically are used to inflate and to deflate the balloon. The balloon or inflatable member be situated in a recess in the outer wall of the inventive catheter. Additionally, the distal end of the catheter past the balloon may be tapered. The catheter has a very low profile as compared to other catheters of the neurovascular balloon catheter genre. It may include other features such as variable stiffness along the axis of the device and anti-kinking components. The balloon may be compliant in nature.

  • Patent number: 6634117
    Abstract: The method serves for drying an active part containing at least one winding and solid insulations. The active part is arranged in a vacuum-tight housing and is heated there to a final temperature value (Tfin) by means of warmed oil and by means of a current (I) carried in the winding. The warmed oil is sprayed in the housing at reduced pressure (p) and with the current (I) switched on. At the same time, water is extracted from the active part. The sprayed oil is collected on the housing bottom, after discharging heat to the active part, and, after rewarming, is sprayed once again in the housing at reduced pressure and with the current switched on. The active part is thus dried particularly quickly and carefully.

  • Patent number: 6626827
    Abstract: A fluid management assembly for use in an endoscopic procedure is provided. The assembly comprises a first line for fluid to flow therethrough from an endoscope to a Y-connector and a second line for fluid to flow therethrough from a drape to the Y-connector. The Y-connector is also in fluid communication with a third line which connects the Y-connector to a suction source which supplies a suction force and receives the fluid. According to the present invention the Y-connector is located in close proximate relation with respect to the suction source and the first and second lines are preferably co-joined along a portion of their lengths. The first and second lines define scope and drape legs, respectively, which are elongated in comparison to more conventional designs.

  • Patent number: 6623470
    Abstract: An apparatus for controlling fluid volume in a patient includes a fluid source (16) and a fluid conduit (32, 34, 36) for carrying fluid from the fluid source to the patient (12). A controllable infusion pump (30) pumps fluid from the fluid source to a peripheral vein of the patient through the fluid conduit. An occluder (100) for blocks fluid communication between the fluid source and the patient through the fluid conduit. A fluid pressure sensor (80) periodically senses fluid pressure in the fluid conduit. The apparatus further includes a controller (86) for determining a peripheral venous pressure value from the sensed fluid pressure in the fluid conduit after the infusion pump is stopped and the occluder blocks the fluid communication between the fluid source and the patient through the fluid conduit. The peripheral venous pressure is indicative of the patient's means systemic pressure and the fluid volume of the patient.

  • Patent number: 6622645
    Abstract: A method and system for combustion of fuel in a boiler in which flue gasses are produced. The boiler includes a source of fuel, a source of air, and a controller for controlling the ratio of the source of air and the source of fuel inputted into the boiler. A sensor is used for measuring the concentration of oxygen in the flue gasses. The controller is adapted to calculate the amount of air entering the boiler based on the amount of oxygen in the flue gasses to thereby adjust the air to fuel ratio to include calculated air input and air input from the source of air. A preferred fuel is pulverized coal. The method and system provide for the air to fuel ratio to be adjusted to optimize efficiency as well as to minimize NOx production.

  • Patent number: 6618957
    Abstract: The invention described herein pertain generally to a process for drying and/or pathogen reduction as well as an apparatus effective for the same, the process comprising the steps of feeding a sample containing water onto a mesh conveyor belt; transporting the sample into a heated chamber having an air flow about, around and through the sample; exposing said sample to at least two sources of microwaves in non-parallel alignment to each other; and collecting the sample. The at least two sources of microwaves are from a split waveguide assembly, producing microwaves which are essentially 90° out of phase to each other. The heated chamber is between approximately 75° C. and 125° C. The convection heating supplements the microwave heating thereby both heating the sample from the outside in and also from the inside out. The microwave frequency is between 915 MHz and 1000 MHz, preferably approximately 915 MHz.
