Abstract: The invention concerns a device for generation of ion network for water treatment in tanks, especially for reduction of cloud and for stabilization of water surfaces, where the device is arranged on a floating body equipped with a drive for initiation of mutual motion of the floating body and water, whereas the floating body is equipped with an ejector and at least one source of electrolytically and/or photocatalytically treated water connected with an outlet (9) that leads into ejection and/or ejected water of an ejector. Eventually, an inlet of chemical agents (11) and/or an inlet of biological agents (12), an inlet of oxidation agent (13) or an inlet of air (14) lead into ejection and/or ejected water of the ejector.

Abstract: Variable transmission gear particularly for bicycles comprising a transmission element such as a chain or a belt which is in engagement with a driving and a driven rosette, one rosette consisting of two parts adapted to be mutually shifted along straight guidings, the axis of said guidings being parallel and passing beyond the axis of supporting shaft.

Abstract: The invention relates to the suspension of a vehicle for rugged terrain with a wheel or wheel-like ground engaging element, the ground-engaging surface of which has the shape of a body of revolution and which is journalled for free rotation on a primary axle, the primary axle being freely rotatable around a second axle which is connected with the frame of the vehicle. The secondary and primary axles make an angle .alpha. with respect to each other which is less than 90.degree.. Also with respect to a reference plane .tau., perpendicular to a horizontal support plane and passing through the longitudinal axis of the vehicle at least one of said axles making an angle .beta. with the plane .tau. which is less than 90.degree.. The suspension according to this invention is a simple design and no additional control device is required for the adjustment of the travel gear when overcoming obstacles.

Abstract: There is disclosed a cutting press adapted for the cutting of paper, such as discarded paper money. The cutting device is mounted in a support having the shape of a case with open side walls, a feeding conveyor passing through the case forwarding the paper to be cut to the press.
