Abstract: Sealing apparatus of wind boxes at both the ore charge and discharge sides of a Dwight-Lloyd sintering machine provides a plurality of seal members disposed in series in close contact with the bottom surface of pallets of the sintering machine, and a seal chamber communicating with a space provided between these seal members.  The seal members are rotatable rolls having seal plates projectingly installed radially on the outer periphery thereof, and may be rolls with these seal plates held in close contact with the bottom surface of the pallets and the inner surface of the seal chamber, or may be flat seal plates with their flat surface firmly pressed against the bottom surface of the pallets.  In the seal chamber is mounted an independent exhaust fan for the removal of air, further improving sealing performance.  According to the apparatus, it is possible to decrease the amount of sintering exhaust gas, power consumption of main induced fan, and processing costs at subsequent desulfurization and denitrification equipment.

Abstract: COMPENSATION CIRCUIT FOR NULLIFYING DIFFERENTIAL OFFSET VOLTAGE AND REGULATING COMMON MODE VOLTAGE             OF DIFFERENTIAL SIGNALS  Abstract of the Disclosure An apparatus  for nullifying the differential  output offset  voltage  between  the  outputs  of  a  differential amplifier and for setting the DC levels of the outputs to a known  reference voltage  includes  a circuit which cross-couples the opposing AC output signals to obtain only the DC components of each signal.  The apparatus further includes a first  operational  amplifier  to  generate  a  compensation voltage  from  the  DC  components  of  the  outputs  of  the differential amplifier proportional to the amount of offset between  the  DC  components  of  the  outputs  of  the differential amplifier.   The compensation voltage is fed back  to  the  offset  control  inputs  of  the  differential amplifier  to  reduce  the  differential  offset  voltage  to substantially zero volts.  The apparatus further includes a dual voltage divider network having a second operational amplifier that supplies a variable reference voltage to one terminal of each leg of the voltage divider network.   The outputs of the differential amplifier are each provided to a respective  other  terminal  of  the  dual  voltage  divider network.   The second operational amplifier has a reference voltage on one of its inputs.  A signal responsive to the common mode output voltage from the differential amplifier is provided to the other input.   The second operational amplifier provides an output voltage that is responsive to the  common  mode  voltage  output  from  the  differential amplifier.   The output voltage from the second operational amplifier provided to the terminals of the dual voltage divider network varies such that the voltage outputs from the voltage  divider network have a  common mode voltage substantially equal to the reference voltage.

Abstract: The invention relates to a blocking oscillator switched mode power supply which is supplied with a primary voltage Up obtained by rectification of the AC line voltage. Because the line voltage varies, the secondary voltage which supplies electrical equipment is stabilized by means of a switched mode power supply. The maximum power from the supply generally depends on the primary voltage Up. The present invention has the objective of eliminating this disadvantage of the known switched mode power supplies. To this end, according to the invention, a correction circuit actuated via a voltage divided is provided, the voltage divider being connected to the primary voltage Up. The correction circuit is designed so that it keeps the breakpoint of the secondary current Is constant. It is thus possible to economize on the normally required overdimensioning of certain parts of the circuit, especially of the transformer, converter, and switching transistor, while on the other hand the invention can be realized at little cost.

Title: Capacitively commutated brushless dc servomotors
Inventor: MILLER GABRIEL L
IPC: H02K41/02
Filed: 1989-10-12
Granted: 1994-08-23
Abstract: Abstract There are disclosed both one- and two-dimensional, high resolution, brushless DC servomotors that are linear, rotary, planar and cylindrical in nature. All of these employ a capacitive method for deriving the required position and motorcommutation information. In suitable circumstances, particularly two-dimensionalplanar motors on air bearings, the method allows the use of the motor ferromagnetic cores themselves as the capacitive position sensing elements. This leads to a particularly simple and compact type of servomotor design. In addition, since such motors can move at high speed, there are also disclosed two transformer coupled methods for handling the current drive to the motor windings. Both methods are simple, energy efficient, applicable to motors of any number of phases, and in addition, handle motor direction reversals automatically.
