Abstract:
A housing of a flotation device has a flotation chamber with at least one inlet for a suspension. The flotation device has at least one foam collecting unit, arranged on an upper face of the housing, for receiving and discharging a foam product, and at least one fluid distribution element, provided above the at least one inlet in the flotation chamber, for generating a flow directed toward the at least one foam collecting unit. The vertical position of the at least one fluid distribution element is variable above the at least one inlet in the flotation chamber.
Abstract:
A flotation device for separating off a valuable mineral from a suspension, has a housing having a flotation chamber, a foam collector for removing a foam product formed in an upper region of the flotation chamber, a feed arrangement for feeding gas and/or suspension into the flotation chamber, an adjustable orifice via which the flotation chamber is horizontally divided into an upper part and a lower part and an open internal diameter of the flotation chamber is locally avoidable. The orifice is arranged completely in a suspension region of the flotation chamber. A measuring arrangement determines a variable in the operation of the flotation device. A control appliance connected to the arrangement automatically adjusts the orifice in dependence on the at least one state variable.
Abstract:
An oil/water emulsion is mixed with functional solid particles to agglomerate oil droplets and/or water droplets having functional solid particles and the functional solid particles are hydrophobicized for the agglomeration of oil droplets or are hydrophilicized for the agglomeration of water droplets. This enables oil and water to be separated from an oil/water emulsion under gravitational forces.
Abstract:
A device for separating ferromagnetic particles from a suspension may include a tubular reactor through which the suspension can flow and which has an inlet and an outlet, and a means for generating a magnetic field along an inner reactor wall, and a displacement body arranged in the interior of the reactor. Means for generating a magnetic field are provided on the displacement body, on an outer wall of the displacement body.
Abstract:
A method for introducing dust into a molten bath of a pyrometallurgical installation is described. According to the method, a carrier gas containing dust particles is guided through a heating zone of an electrode less plasma torch, the gas being converted to a plasma by inductive heating prior to being blown into a region of the installation which receives the molten bath.
Abstract:
In the case of an electromotive auxiliary drive for vehicles, particularly for windscreen wiper drives or adjustment drives for vehicle elements with a secondary transmission for the electromotor, with at least one magnetic sensor, which acts in conjunction with a signal transmitter or permanent magnet arrangement formed of at least one permanent magnet and rotating with a drive shaft or a gear wheel in order to record the angle position and/or modification of the angle position of the rotation of the shaft or the gear wheel, the permanent magnet arrangement is arranged on the front side on a shaft end bedded in a bearing arrangement or on a drive element bedded in the bearing arrangement and arranged on the shaft. The at least one magnetic sensor is arranged opposite the permanent magnet arrangement in the direction of the shaft axis within the bearing arrangement.
Abstract:
A bearing arrangement for an output shaft of a gear of an electromotive windscreen wiper drive has the output shaft and an eccentric grommet configured to align the output shaft with at least one further gear element by rotation around an grommet axis. The eccentric grommet is anchored by being pressed into a receiving opening of a bearing housing for a press-fit. The eccentric grommet a has no flange.

Abstract:
In devices for producing strong current high power impulses, the electronic components, for example, passive components such as capacitors and/or switch elements, such as semi-conductor switches, diodes or similar elements, need to be protected against overcurrents in the event of an error function. Generally, serial resistance and serial inductance are used. The serial resistance and the serial inductance are preferably combined together in such a manner that a coil comprising necessary resistance and inductance values is produced.
Abstract:
In a drive for a switching device, stored energy is converted into a rapid switching movement and a switching body is hence activated. An energy conversion occurs as a result of an underwater electrical discharge, by the application of stored electrical energy in order to evaporate a drive medium, by which an exclusive pressure is generated for operating the switching body. An advantage is presented of the possibility of the complete recondensation/recombination of the working medium and a greatly increased lifespan compared to a conventional explosive drive.
