entr Binding system using binder pieces with concentric cylinders By www.freepatentsonline.com Published On :: Tue, 14 Oct 2014 08:00:00 EDT A binding system for binding a set of media sheets, including first and second binder pieces, each including an end cap, a retainer, a cylinder and a connection mechanism. The retainer has an arc-shaped cross-section having an associated arc angle thereby providing an opening slot that extends along a length of the retainer. The retainer and the cylinder are connected to the end cap such that the cylinder is positioned within the retainer. The binder pieces are adapted to bind the set of sheets of media by inserting the set of media sheets into the first and second binder pieces such that the media sheets are wrapped around the cylinders and extend out of the opening slots in the retainers, and engaging the connection mechanisms to connect the first and second binder pieces together.

entr Binding system using concentric cylinders By www.freepatentsonline.com Published On :: Tue, 16 Dec 2014 08:00:00 EST A binding system for binding a set of media sheets, including a cylinder having an outer diameter and a length, and a retainer fabricated from a flexible material. The retainer has an arc-shaped cross-section having an inner diameter and an associated arc angle thereby providing an opening slot that extends along a length of the retainer. The binding system is adapted to bind the set of media sheets by wrapping the media sheets around the cylinder and inserting the wrapped cylinder into the retainer with the wrapped media sheets extending out of the opening slot in the retainer. The inner diameter of the retainer is less than the sum of the outer diameter of the cylinder and a total thickness of the wrapped media sheets so that the retainer flexes to provide a clamping force to bind the media sheets.

entr Cylindrical liquid filtering device with central rotor, supported filter elements, and divergent inner wall radii that form curvilinear wing-shaped bulges to guide the liquid toward the filter elements By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT A device for filtering liquids has a container, units for introducing a liquid to be filtered into the container, a container outlet for unfiltered liquid to be discharged from the container, and at least one rotor, which is drivable to rotate around the container axis. The rotor has a hollow shaft mounted in an end wall and a support device fastened thereon for filter elements, which are arranged with a clearance to the container axis or rotate around their own axis. The interior of the filter elements opens via the support device and the hollow shaft out of the container as the discharge for filtered liquid. To provide improved filtration conditions, the container internal radius of the inner wall of the container circumferential shell is enlarged up to a maximum in the container circumferential direction while bulging the inner wall between two minima. The bulge forms a guide unit which guides the liquid toward the filter elements. Full Article
