Abstract: A device and system for purifying a fluid is provided. The system includes a tank having an interior space and a media container disposed within the interior space. A valve is provided that cooperates with an element within the interior, the valve being movable between an open and a closed position. The valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position. The valve further being configured to move to a closed position when the element is positioned within the interior space.

Abstract: A generative interactive video computer-implemented method and system applies trained computer-implemented neural networks to generate a sequence of images, which may comprise a video, and which contains identified objects, and then delivers the sequence of images to a user. The sequence of images may be further generated in accordance with an inference of a preference from user behavioral information. The identified objects may be provided to the system in the form of natural language and/or images. The system then generates and delivers to users natural language-based responses to user requests for information with respect to the identified objects, including attributes that are associated with the identified objects. Users may direct the system to generate video-based virtual environments that include representations of the identified objects.

Abstract: A method configured according to the invention receives a user input. Then a recording of an audio file and a corresponding audio timer are initiated. When the audio timer times out, the recording of the audio file is ended, and an image file is captured. In an embodiment of the invention, the audio recording is ended and the image file is captured if the audio timer times out prior to receiving a second user input. In an embodiment of the invention, if the audio timer does not time out prior to receiving a second user input, an image file is captured. In an embodiment of the invention, if the audio timer does not time out prior to receiving a third user input, then the recording of the audio file is ended.

Abstract: A process for producing liquid and, optionally, gaseous products from gaseous reactants comprises feeding gaseous reactants into a slurry bed of solid particles suspended in a liquid; allowing the reactants to react as they pass upwardly through the slurry bed, thereby to form liquid and, optionally, gaseous products; and separating liquid product from the solid particles by passing, in a filtration zone within the slurry bed, liquid product through a filtration medium in a first direction, so that a cake of the solid particles forms on the filtration medium. The passage of liquid product through the filtering medium is interrupted. The filtering medium is then backflushed by passing a flushing fluid through the filtering medium in a second direction, opposite to the first direction, for at least portions of the periods that the liquid product passage is interrupted, thereby to dislodge the cake from the filtering medium.
