Title: Processing composites of solid organic, inorganic, metallic and mineral materials in flowing stream
Inventor: ENGEL RUDOLF
IPC: B07B9/00
Filed: 1996-09-14
Abstract: This new method processes the components of composites, comprising solid organic and/or inorganic composite materials. These may include composites of metals, plastics and/or minerals. Particles are formed from the composite and added to a transport fluid. Relative to the flow of this mixture, a flow obstruction crosses transversely, causing turbulence. Motion causing acceleration and separation is generated, setting up forces which exceed the bonding forces between solid particle components. Such forces arise from centrifugation and friction, and separate or pull-apart layers of the composites forming the particles. Apparatus for carrying out the process is also claimed.

Patent DE-19725629-A1 (DE)
Inventor: WOBBEN ALOYS
IPC: H02M7/539
Filed: 1997-06-17
Abstract: The invention relates to an inverter for inputting sinusoidal currents into an alternating current network. The invention seeks to improve resistance to short circuiting and to reduce the risk thereof. According to the invention, only one switching unit is used to generate a semi-oscillation of a sinusoidal oscillation. In order to generate a positive semi-oscillation of a sinusoidal oscillation, a second switching unit is used in addition to the one used to generate the negative component of a sinusoidal current. As a result, only one switch pertaining to a switching unit is clocked or actuated to generate a positive semi-oscillation. Another switch is clocked or actuated to generate a negative semi-oscillation of a sinusoidal current. The risk of a short circuit between both switches is thus reduced to the period occurring between switching from the positive to the negative or from the negative to the positive semi-oscillation.
