Title: Facility for cleaning flue gases in heating systems
Inventor: DOERENKAEMPER WILHELM
IPC: B01D50/00
Filed: 1987-07-01
Abstract: A facility for cleaning or detoxifying flue gases generated in the operation of furnaces for heating systems and removed by forced convection comprises two or more cleaning devices located one after another in the direction of flow of the flue gas, the upstream one consisting of a filter device and the downstream one of a catalyst device. Both cleaning devices are located in a separate cleaning duct which branches off from the vent flow path and rejoins it, and also contains a blower for the forced convection of the flue gas. An isolating valve associated with the cleaning duct can be moved from an open position that releases the flue-gas access for operation of the cleaning devices, depending on interruptions in service of the cleaning devices, to a closed position that blocks the access of the flue gas to the cleaning duct; simultaneously, the vent flow path for bypassing the cleaning devices to vent the flue gases is released.

Title: Capacitive distance sensor
Inventor: HABERLAND RUEDIGER PROF DR ING
IPC: G01D5/24
Filed: 1987-10-14
Abstract: The invention relates to a capactive distance sensor which overcomes alterations in the dielectric constant in the gap between the sensor and surface to be measured by the use of multiple measurement surfaces at various separation distances. The sensor can be operated such that the capacitance of each of the surfaces with the opposite surface is measured and, from the measured values, the known surface areas as well as the known separation distance between the surfaces, the dielectric constant and the separation distance can be calculated. Simpler, and more suitable to application as a sensor, is a mode of operation with dividing evaluation electronics which directly deliver only the terms relating to the separation distance and suppress the dielectric constant.

Title: Magnetic separator for sorting weakly magnetisable substances
Inventor: WUNDERLING KARLHEINZ
IPC: B03C1/16
Filed: 1988-02-09
Abstract: The invention relates to a magnetic separator for sorting weakly magnetisable substances and is used preferably for separating weakly magnetisable substances, such as non-ferrous metals, minerals and ores. The magnetic separator according to the invention is constructed in such a manner that a tongue-shaped pole shoe having a protruding bulbous nose is arranged above or in front of the vertical central axis of the profiled pole roller. The profiled pole roller is preferably constructed so as to be of a helical shape. An essential condition for realising the solution according to the invention is that the curves of the bulbous nose have a greater curvature than the radii or curvatures of the profile tips of the pole roller. Using this magnetic separator according to the invention, it is achieved that the sorting of magnetic from non-magnetic particles takes place even before the detachment point of the discharge parabola between a pole roller and a pole shoe, so that mixing on the sloping track of the profiled pole roller can no longer occur.

Filed: 1988-07-28
Abstract: The permanent-magnetic body (2) consists of a sintered superconductor material of the type II, has been subjected to a magnetic field treatment and is held below the critical temperature of the superconducting material. Hitherto, corresponding bodies required elaborate liquid-helium cooling technology. According to the invention, provision is therefore made to select as the superconducting material an oxide-ceramic superconductor material which can be held below its transition temperature (Tc) by means of liquid nitrogen (LN2). In particular, the superconductor material can be selected from the system Me1-Me2-Cu-O, the component Me1 at least containing a rare earth metal (including yttrium) and the component Me2 at least containing an alkaline earth metal. Advantageously, corresponding materials having a relatively low critical current density can be employed. <IMAGE>

Filed: 1988-12-21
Abstract: An arrangement for providing power to a cooking magnetron uses a full wave bridge inverter circuit 22. Four semiconductor switches 46, pairs of which are switched on and off by a pulse width modulation control circuit 24, provide power to a primary winding 60 of a power transformer 26. A secondary winding 64 of the power transformer supplies the power to the magnetron. The control circuit switches two of the four transistors 46F, 46T on and off by way of an isolated drive circuit 52, 54 such that the control terminals of the semiconductor switches float with respect to the other two semiconductor switches. The control circuit 24 includes pulse width modulation circuitry which provides a control pulse having a width proportional to an input provided across a transconductance amplifier. A signal dependent upon magnetron current 94 is used as part of a feedback loop such that magnetron current is stabilized against variations due to line voltage changes. Magnetron filament voltage may be regulated using a saturable reactor, and over-temperature and excess current protection may be included. <IMAGE>
