Patent CA-2070213-A1 (CA)
Title: Fluidized bed combustion method utilizing fine and coarse sorbent feed
Inventor: ABDULALLY IQBAL F
IPC: F23C10/10
Filed: 1992-06-02
Abstract: A fluidized bed combustion method utilizing fine and coarse sorbent feed to control the temperature of a cooling fluid such as water or steam circulating through a fluid flow circuit of a fluidized bed combustor. Fuel particles, such as coal, along with relatively fine and relatively coarse sorbent material, such as limestone, are fed into the furnace section of a fluidized bed reactor.      The fuel is combusted, and a fluidizing gas such as air is introduced into the furnace section. Flue gases arid entrained material pass from the furnace section, and the entrained material is separated from the flue gases. The separated entrained material passes to a recycle heat exchange section and is cooled before being passed to the furnace section. The recycle heat exchange section is provided with heat exchange surfaces which form part of a fluid flow circuit to transfer heat from the separated entrained material to a cooling fluid such as water or steam which is circulating through the circuit. The ratio of fine to coarse sorbent feed is controlled to control the heat transfer from the separated entrained material in the recycle heat exchange section to the cooling fluid, thereby controlling the temperature of the cooling fluid and enabling the temperature of the cooling fluid to be held constant over a range of fluidized bed reactor loads.

Title: Method and device in closed heating plants
Inventor: GLOEERSEN STIG
IPC: F23L15/04
Filed: 1991-01-08
Abstract: A method of utilizing the high energy values of fossile fuels in central heating boiler systems. Tie boiler system comprises a processor which include an air heat pump (5) whi~~ functions to cool the system flue gases by condensation. A first fan (10) generates a first circulation (C1) of boiler room air, via the air heat pump (5), this circulation of air also passing through a heat exchanger (4) where heat exchange takes place with the flue gases. A second air circulation (C2) is generated with the aid of a flue-gas fan (7) which removes flue gases from the boiler by suction, thereby generating a subpressure in the boiler room so that fresh air will be drawn in from the ambient surroundings, this air passing through the heat exchanger (4). A lower pressure is maintained on that side of the heat exchanger (4) on which the air/flue gas mixture (C2) flows into the heat exchanger, whereas a higher pressure is maintained on the other side of the heat exchanger (4) on which the cooling boiler-room air circulates (C1). This will ensure that flue gases will always flow out to the free atmosphere, via the heat exchanger (4).

Patent CA-2082077-A1 (CA)
Inventor: BARTOW NEIL G
IPC: H04L69/40
Filed: 1992-11-04
Abstract: A  system and method for  asynchronously transmitting data blocks, in parallel, across multiple fibers in a serial manner.   Frame groups are provided as a mechanism to transmit associated data serially on each fiber and tie the data being transmitted together.   The frame groups do not have sequence numbers,  therefore,  the receiver determines which frames are part of a frame group by the arrival times of the individual frames.  In one embodiment, the transceivers for each  member  of  the  parallel  bus  asynchronously  achieve synchronism at each end of the fiber.  Thus the need for a common clock is eliminated.  The receivers on each side of the bus determine the relative skew for each conductor by performing  skew  measurements  on  a  calibration  message generated by the transmitters on the other side of the bus. When the skew on all conductors, viewed from both sides of the bus, has been determined, the skew values are exchanged across the bus, thus enabling the transmitters to set proper frame spacing.

Filed: 1992-11-30
Abstract: A method and apparatus of the alternately displaying two separate data entry views of an electronic mail object. A  first  data  entry  view  graphically  displays  a  visual metaphor  of  at  least one  sheet  of  note paper partially overlying an envelope, with only a portion of the envelope visible  in the  display.   A  second  data  entry  view graphically  displays  a  visual  metaphor  of  an  envelope overlying a portion of at least one sheet of note paper, with only a portion of the sheet of note paper visible in the display.  In either view, the overlying displayed sheet of note paper or envelope is active for the entry of message text or destination  information,  respectively,  while  the partially displayed  envelope  or  sheet  of note  paper  is inactive to such data entry.  Instead, the selection with a pointing device of the partially obscured envelope or sheet of note paper causes that selected envelope or sheet of note paper to be fully displayed and rendered active for data entry while rendering inactive and partially obscuring the previously active field.

Title: Method and device for the extraction of blocks from a rock formation
Inventor: ANTUNES CACIQUE GERALDO
IPC: B28D1/00
Filed: 1992-07-16
Abstract: Extraction from rock formation of blocks of rock that are already of a paralellepiped shape and thus do not require final time consuming finishing operations involves cutting a long slot in the formation beneath a slice of rock to be removed and then drilling various orthogonal series of parallel aligned perforations to define cutting surfaces that are separated using metal plugs applied to the perforations. In this manner parallelepiped shaped small blocks are obtained directly and can be removed from the formation in a stage virtually ready for commercialisation. Equipment in the form of an extractor (1-28) permits the simultaneous formation of the slot and the perforations.
