  • Patent number: 10940298
    Abstract: A self cleaning inlet head for use on a shunt. The head has a tube with openings disposed in predetermined positions in its wall, and a cleaning element installed inside the tube. The cleaning element may comprise a central shaft with a number of bristles protruding therefrom, preferably in locations substantially identical to the positions of the openings in the wall of the tube. Mutual vibratory motion between the cleaning element and the tube causes at least some of the bristles to enter the openings, thereby keeping them clear, and preventing tissue growth into them. The vibratory motion may be generated by the action of an external field on a responsive part of the cleaning element, such as an external magnetic field operating on a magnetic or magnetized part of the cleaning element or the bristles. Alternatively, the external field may be an ultrasound field operating on the bristles.

  • Patent number: 10932437
    Abstract: A wheeled manure-removal vehicle for removing manure from an animal-shed floor includes a scraper assembly for scraping the manure together into a manure-storage space by scraping across the animal-shed floor. The scraper assembly includes a flexible, strip-shaped scraping element which is partly arranged around the manure-storage space and a rolling body. The rolling body extends on a side of the scraping element which faces away from the manure-storage space in order to be in contact with the scraping element at least while scraping the manure together, and has, on the side facing the scraping element, a rolling surface which is convexly rounded towards the scraping element. The use of the rolling body for contact with the scraping element has an advantageous effect on the life of the scraping element on the vehicle.
