  • Patent number: 9815010
    Abstract: A water filtration system utilizes a housing configured to utilize various types of filter media and having a press-sealed closing system. The closing system includes a head portion defining a head opening, a lock member, and a lid member. The lock member releasably engages the head portion such that an abutment section of the lock member projects into the head opening. The lid member is received by the head portion to cover the head opening, and has an outward-facing press section configured to abut an inward facing portion of the abutment section of the lock member when the lid member is covering the head opening. Pressure generated within the housing during water filtration presses the lid member in an outward direction and causes the lid member press section to press against the abutment section of the lock member to substantially prevent disengagement of the lock member from the head portion.

  • Patent number: 9776113
    Abstract: A rotatable basket extractor for use in extracting oil from oleaginous feed material is disclosed. The extractor includes a rotatable rotor that includes a plurality of baskets extending radially outward from a central shaft, and the baskets receive and transport the oleaginous feed material while a motor rotates the baskets between a feed inlet and a feed outlet. The rotor is located within a housing and positioned above a screen through which miscella that drains from the feed material passes. The miscella is collected in a trough located below the screen and is sprayed onto the feed material bed positioned within the baskets in a counter-current manner. A suction device pulls vapor down between the particles of the feed material bed to decrease the drainage time of the miscella through the feed material.

  • Patent number: 9731232
    Abstract: A liquid filter having a housing and a hollow insert. The housing has a dirty liquid feed, a clean liquid outlet and a drainage channel, and is closed by a detachable cover. In the channel, a valve is arranged, having a valve body axially displaceable between a closed and an open position. The cover on the housing presses the valve body into the closed position. When the cover is removed from the housing, the valve body is carried to its open position and then is detachable from the cover or insert and is retainable in its open position by a spring holding element. The holding element automatically expands into the opening position by spring force and engages a spring element restraint holding the valve body in its open position. A force contracts the spring element, displacing the valve body in the closing direction, releasing engagement with the spring restraint.

  • Patent number: 9707497
    Abstract: A filter assembly and cage and/or capsule apparatus including upstream and downstream and optional intermediary supports having modified features to maximize fluid flow through the filter assembly. The cage apparatus has a plurality of posts with stacked ridges that function as cap engaging teeth. A cage end cap is formed with a plurality of slots corresponding in configuration and position to the plurality of posts. The combination of slots and ridges interact to create a locking mechanism to adjustably secure the end cap to the cage and to generate the necessary compression to seal the enclosed filter discs and supports. The upstream supports are formed with channels in an outer ring and optional channels in radially extending ribs to improve fluid ingress and transfer to the filter discs. The downstream supports are formed with channels or tunnels in an inner ring to facilitate filtrate egress into a filter assembly outlet.
