Patent CA-2001781-A1 (CA)
IPC: H04J3/08
Filed: 1989-10-30
Abstract: ABSTRACT         An improved drop/insert multiplexer for use in a channel access unit that uses channel slots in common for data channels in first and second directions, and uses less wiring between a multi-plexer/de-multiplexer section and a channel section thereof is provided by adopting a time division multiplex transmission system for transmitting receive and send channel pulses.  The drop/insert multiplexer has at the receive side thereof, a time slot phase difference setting stage for providing a predetermined phase dif-ference between received timing signals as well as receive data from the first and second directions.  A receive channel pulse generating stage generates multiplexed channels pulses.  A receive channel pulse decoding stage and a PCM decoder reproduces a voice signal by receiving selected received data and, at the send side thereof, a time slot phase difference correcting stage corrects the set phase difference for sending out channel data to the first and second directions.  A send channel pulse generating stage generates multiplexed channel pulses.  A send channel pulse de-coding stage and a PCM coder produces PCM signals to send out to the first and second directions as channel data.

Abstract: AUGER FLIGHT WELDER      ABSTRACT             An apparatus for rebuilding the worn outermost edge of a flight of an auger section by depositing a continuous bead of weld material along the extent of that edge. Attached to a support frame is chuck means for releasably grasping opposite ends of the auger section and holding it horizontally 80 that it may be driven in rotation about its longitudinal axis, and a guide rail affixed to the frame to extend above and parallel to the auger axis. A carriage assembly is mounted to move freely along the rail and includes a carriage plate mounted for vertical movement; which plate has a follower wheel with a grooved rim, mounted to its lower end.  This wheel is adapted to ride an upper portion of the auger flight and to thereby vertically support the carriage plate and to urge it in horizontal movement as the auger  is rotated.    The carriage plate also adjustably mounts the welding head of an arc-welder including an automatically fed welding wire  that  is  aligned with the  flight  edge.    This arrangement  allows  the  welding  head  to deposit  a continuous bead along the flight edge as the auger section is rotated.

Filed: 1990-06-13
Abstract: In a multiprocessor system comprising a plurality of processors and a main memory common to the processors, each processor comprises at least one vector calculation unit which is specific to a vector calculation and which is independent of the vector calculation units in the other processors.  A register holds a configuration signal representative of configuration of the vector calculation units in each processor.  An access control unit controls access operations of the processors on the basis of the configuration signals in the processors to make the processors selectively access the main memory.  Thus, the processors individually carry out the vector calculations to individually access the main memory.

Title: Apparatus for producing quality steel directly from iron ores
Inventor: PETERSON OREN V
IPC: C21C7/072
Filed: 1990-08-29
Abstract: ABSTRACT OF THE INVENTION    The apparatus of the present invention is for producing quality steel directly from iron ores with reducing gas. The apparatus comprises  three vessels:  (1) a primary reduction vessel, (2) a reducing gas production vessel and (3) a secondary or final reduction vessel.  (3) is a high temperature vessel having two hoppers at the top, one into which the partially reduced iron ores are introduced by a conveyor from the bottom of vessel (1), and the other for holding the iron ores and slag ingredients. Molten steel and slag floating on it collect in the bottom where they are held prior to batch withdrawal. Conduits are provided in the wall of vessel (3) (a) to withdraw molten steel and (b) to withdraw molten slag. A plurality of tuyers having arcuate ends are rotatably mounted in the wall above the molten slag layer for introducing (1) oxygen, (11) coke and (iii) reducing gas. By rotating the tuyers, the angle of introduction of the fluid ingredients can be changed to cause them to impinge on the surface of the slag and cause it to rotate clockwise or counterclockwise. The coke and oxygen react to form a reducing gas that rises countercurrent to descending partially reduced iron ores and slag ingredients and flows from the top of the high temperature vessel into the gas production vessel where waste heat is utilized to convert carbonaceous materials, steam and carbon dioxide into hot, strong reducing gas comprising hydrogen and carbon monoxide. Conduits are provided to conduct (1) this gas to (a) the primary and (b) the secondary reduction vessels and (2) sulfur and phosphorus vapors to recovery vessels.

Abstract: DE LA RUE GIORI S.A.                LAUSANNE/SWITZERLAND       Apparatus for invalidating security prints printed on print carriers.            ABSTRACT            The  apparatus has as many invalidating units (E) arranged next to one another as  there  are  longitudinal  rows  of security  prints   on   the   print  carriers  (P).  Each invalidating unit (E)  has  a stand  (1),  a  trough  (3) vertically  displaceable  in  the  latter and intended for receiving  ink  (4),  a  centrifugal  wheel  (7)  rotating continuously above  the  trough  (3),  and a shutter (11) which interacts  with  an  orifice  (10)  of  a  cowl  (9) covering   the  centrifugal  wheel  (7).  By  means  of  a controlled  actuating  member  (6),  the  trough  (3)   is adjustable between a raised working position, in which the centrifugal wheel (7) dips into the ink  and  the  shutter (11)  exposes  the orifice (10), and a lowered position of rest, in which the centrifugal wheel (7) does not dip into the  ink  and  the  orifice (10) is covered by the shutter (11).  Control  takes  place  whenever  a security  print previously  detected  as a misprint and to be  invalidated in one or more longitudinal rows  of  the  print  carriers passes  the  orifice  (10)  of the respective invalidating unit, so that this misprint is sprayed  with  ink  by  the centrifugal  wheel  (7)  through the orifice (10) which is then free.
