  • Patent number: 6829804
    Abstract: A filtration arrangement of a vacuum cleaner includes a floor-engaging base unit, a body portion pivotally mounted on the base unit and a suction motor/fan assembly located in either the base unit or body portion. A dustcup is mounted on the body portion and is in fluid communication with a first air path so as to receive dirt laden air therefrom. A cyclonic member is disposed over the dustcup and is effective for imparting rotational motion to the dirt laden air entering the dustcup. An air tube is mounted centrally within the dustcup and extends from the bottom of the dustcup to an area near the top of the dustcup. A removable filter member is disposed over the top portion of the air tube. The removable filter has a central opening that cooperatively engages the top portion of the air tube to establish a second air path that extends from inside the dustcup to outside atmosphere through the suction motor/fan assembly.

  • Patent number: 6821486
    Abstract: The invention relates to a multi-autoclave and details of its design, a method for automated synthesis of zeolites in the multi-autoclave, and furthermore, to applications of the multi-autoclave for an automated synthesis which is optimized simultaneously with regard to several synthesis parameters in the synthesis of zeolites. The multi-autoclave consists typically of a pressure vessel/autoclave having from 10 to 10,000 small, separated chambers lined with an inert material, with each chamber typically having a volume of 0.2-2 ml. The chambers preferably are formed as through-going perforations in a central block and the perforations are sealed by balls, septa, stoppers or such which are placed at the bottom and top of each through-going perforation. Metal plates are placed over and under the central block so that a closing mechanism is pressed against the edges of the perforations with sufficient load to enable the chambers to be filled with aqueous mixtures and to be heated to 200° C.
