Title: Lifting coke oven charging hole cover - using magnet suspended from carriage sliding in profiled slots on charging car plate
Inventor: GEBHARDT GUENTER
IPC: C10B25/20
Filed: 1975-06-21
Abstract: A magnetic device to lift off the charging hole covers of coke ovens has a lifting magnet on a frame which is suspended on chains from a carriage. The latter moves on a pair of rollers in slots of a central plate below the platform of the charging car. These slots are arranged in a vertical plane one above another and have a contour which enforces first a vertical lifting and then a sideways shifting when a power actuator moves the carriage. Before this, a crank device on the frame turns the magnet and the cover several times in both directions to free the cover. This is a simpler and less expensive design than on using link chains coupled to sliders. It makes better use of the space between over ceiling and charging car platform.

Title: Brushless motor fed from DC source - has auxiliary start up circuit ensuring correct run up direction
Inventor: RUFF GERD
IPC: H02K29/12
Filed: 1975-07-22
Abstract: The motor is wound with three stator phases to which current is switched sequentially by an operational amplifier and power transistor circuit. An additional winding on the stator provides the necessary positional information for the switching circuit. To ensure the correct run up direction a time delayed control element is added which produces three outputs lasting for the start up period (t0-t2). The first lasts the whole period and earths the amplifier inputs, thus rendering the sequential switching inoperative. The second lasting a s shorter time (t0-t1), switches on two motor phases to bring the permanent magnet rotor to a known starting position. The third follows the the second (t1-t2) in time. It switches on the other phase of the motor thus causing rotation in the required direction.

Title: Directional loudspeaker system for conference halls - has microphones located on dias with outputs separately connected to delay circuit
Inventor: REICHARDT WALTER PROF DR ING
IPC: G10K11/34
Filed: 1976-02-10
Abstract: The directional loudspeaker system, for large conference halls allows listeners to detect the speaker by the direction of his voice. Several microphones are locatead on a dias and their output are each connected separately to a delay circuit. The delay circuits introduce delas to the signals appropriate for that microphone's relative position on the dais. The delayed signals are then added together in given combinations, and their sums are each used to drive one loudspeaker located at the front of the dais. The relative sound intensities produced by the loudspeaker thereby depend on the position of the speaker relative to the microphones.

Title: Cyclonic appts. for removing particles from gases - has rotating element that swirls gas to produce centrifugal force on particles
Inventor: VENAAS KARL
IPC: B01D45/14
Filed: 1976-12-16
Abstract: A device for separating particles from a gas has a rotating truncated cone-shaped element enclosing a free space into which polluted gas is fed by an inlet tube. Clean gas leaves through an outlet tube at the narrow end of the element and separated particles fall into a catch bin below the widest end of the cone. The inlet pipe extends coaxially to the median or narrowest part of truncated cone-shaped space and has one or more outlet opening that direct polluted gas at a tangent and/or parallel to the wall enclosing the free space. A truncated cone-shaped cap can be positioned inside the free space to form an annular space between it and the rotating element. This cap can be fixed to the inlet tube in such a way that the outlets of the inlet tube are situated in the surface of the cap. Alternatively the cap can be fixed to a rotating tube so that it rotates with the rotating element. The element in this case Would be supported from the rotating tube, which also acts as the outlet tube, by means of a flange and gudgeon studs that are fixed to the narrowest end of the truncated cone-shaped element. An inlet tube surrounds the gudgeon studs so that the polluted gas enters the space between the element and the cap at the narrowest end. The cap is fixed to the end of the rotating tube in such a way that it can be adjusted in an axial direction to alter the witdth of the space between the element and the cap. Device can be used for solid particles from a gaseous stream, e.g. cement particles from a flue gas; silicon dioxide dust coming from electrostatic precipitators. The device is of simple construction and takes up little space.
