Patent CA-2153081-A1 (CA)
Inventor: BERNARD JOHANNES GELEIJN
IPC: C21B11/00
Filed: 1995-06-30
Abstract: A method and apparatus for production of iron from iron compounds is provided.  There is a first stage of pre-reducing the iron compounds in a first chamber having a rotationally symmetrical wall, and a second stage of further reducing the iron compounds in a second chamber below the first chamber, fuel and oxygen being supplied to the second chamber.  A reducing gas passes upwardly into the first chamber to effect the pre-reduction therein.          Oxygen is fed to the first chamber.  The iron compounds in the first chamber at least partly melt and then flow downwardly along the wall towards said second chamber.  The iron compounds are introduced into the first chamber in particle form and by means of a carrier gas which provides one or more jets.  The oxygen is fed into the first chamber at least partly in the form of one or more jets having tangential components. The velocity of introduction of the oxygen is greater than the velocity of introduction of the iron compounds in the jets thereof, while the velocity of introduction of the iron compounds is such that the particles reach the wall of the first chamber in an at least partly molten state.

Title: Magazine for supplying work pieces to a robot or production machine
Inventor: SCHMID AUGUST
IPC: B65G59/06
Filed: 1995-12-01
Abstract: A magazine stores a multitude of work pieces (7) in a plurality of stacking units (2) on a turntable (3) for presenting these work pieces one by one in a constant retrieval position for pick up by a robot or production machine.  The stacking units (2) are arranged  around  a  central  vertical  column  (4)  on  the turntable (3).   Each  stacking unit  (2)  has  a retrieval or discharge opening (6, 26) for the work pieces.  A sensor (11) provides a signal that signifies that the particular stacking unit (2) is empty.  A drive mechanism advances the turntable (3) in response to such an "empty" signal through such an angular range that the next stacking unit is positioned to present the work pieces one-by-one in the fixed retrieval location until that stacking unit is empty.   Thus,  the work pieces  are always presented at the same location for an easy retrieval.

Abstract: Waste water treatment uses a combination of continuous and discontinuous water flow in a activation tank, where the required activated sludge concentration is maintained by interrupting an activation process during a period of reduced waste water supply into the equalizing tank, from where the waste water is re-pumped into the activation tank after having accomplished the sludge sedimentation, the excess sludge is pumped off in one lot and the continuous water flow in the activation tank is automatically re-established by raising the waste water level in the equalizing tank.
Patent CA-2164659-A1 (CA)
Title: Method for serial transmission of digital measurement values
Inventor: MEHNERT WALTER
IPC: G08C19/28
Filed: 1995-12-07
Abstract: In a process for the serial transmission of measurement values which are continuously supplied by a sensor and which occur at the transmitter end in digital form, to a receiver, the measurement values are ascertained at such short time intervals that their deviation from the respectively precedingly ascertained measurement value can be represented generally by only two bits of which the one reproduces the sign and the other the value of the deviation. Of the measurement values which occur within a predeterminable period of time, only a respective one is completely transmitted as an absolute value while of the others only the respective incremental alteration values which are related to the one measurement value are transmitted. At the receiver end 'virtual' measurement values corresponding to the measurement values occurring at the transmitter end are synthesised by the transmitted incremental values being added, correctly in respect of value and sign, to the completely transmitted absolute value.

Abstract: A switched reluctance motor includes a rotor mounted for rotation about an axis, and having a plurality of rotor poles, and a stator surrounding the rotor and including first, second and third stator phases.  The motor also includes energizing means for sequentially energizing the stator phases with an energy source to cause rotation of the rotor, based on rotor position information, the energizing means causing one phase to be energized and then deenergized to near a zero current level prior to a point where the rotor pole breaks away from the stator pole.  The energizing means further includes limited current turn on means connected to switch operating means for operating a switch on the one phase to permit flow of limited current through the one phase after it reaches a near zero current level but before the break away point.  The motor further includes circuit means connected to the one phase for permitting the limited current to circulate through the one phase; and current sensing means for sensing the amount of current in the one phase and for determining when the current exceeds a predetermined regenerative current threshold at about the break away point, the energizing means being connected to the current sensing means to use this excess regenerative current information at about the break away point for rotor position information.
