BRONSWERK RADIAX TECHNOLOGY B.V. Patent applications
Patent application number	Title	Published
20110097190	Rotation Device - The invention relates to a rotation device, such as a pump or a hydromotor of the rotating type, wherein a rotation-symmetrical rotor bounds at least two rotor channels together with radial baffles. The rotor comprises two generally goblet-shaped dishes, the innermost dish of which is stiffened by a first stiffening plate which has a peripheral widening, for instance branches in its peripheral zone into at least two rings which are rigidly connected with at least two respective bent peripheral edges, substantially over the whole outer surfaces thereof, to the inner surface of the peripheral edge of the relevant dish such that the stiffness of the peripheral edge of the dish is increased.	04-28-2011
20110084482	Conical Screw Coupling - A screw coupling between two bodies, one having an external screw thread and another having an internal screw thread complementary thereto, which screw threads are superimposed onto two base surfaces monotonously narrowing and widening respectively in the direction of a central axis, the longitudinal section of each of these screw threads relative to the central axis being a periodic univalent function which is continuous at least at the inflection points. The screw coupling has the following features: the first and second derivatives of the longitudinal section of each screw thread along the base surface is a continuous function; the second derivative of the longitudinal section of each screw thread relative to the central axis is a continuous function at least in the region of the inflection points; and the screw threads are in mutual contact over a substantial surface area differing from line contact.	04-14-2011
