Patent CA-2077216-A1 (CA)
Inventor: HENRICSON KAJ
IPC: D21C11/02
Filed: 1992-08-31
Abstract: Chemicals are recovered during the production of cellulose pulp by forming two different sulfidity melts in two different sections of a recovery boiler, and then producing cooking liquors from different melts in dissolving tanks. The liquors may be causticized and/or oxidized, or may be utilized uncausticized. Uncausticized green liquor having a sulfidity of about 70-90% may be used early in a kraft cooking cycle, followed by treatment with low sulfidity oxidized and causticized white liquor. In the continuous digestion of cellulosic pulp, oxygen may be added to the recirculation loops below the black liquor withdrawal to enhance the alkalinity of the slurry and to assist in delignification. Oxidized cooking liquor with low sulfidity can be added to oxygen bleaching and alkali extraction stages downstream of the digester, and a portion of the high sulfidity cooking liquor can be used to produce acid used in an ozone bleaching stage.
Patent CA-2078312-A1 (CA)
Title: Digital data processor with improved paging
Inventor: KAUFMAN MARK A
IPC: G06F12/10
Filed: 1992-09-15
Abstract: Abstract A digital data processing apparatus has a memory element that stores data for access by one or more processes, as well as a secondary storage element, e.g., a disk drive, for non-volatile data storage.  A paging mechanism selectively transfers sets of data between the memory and an associated data file on the disk.  A directory stores "atomic" signals, or bits, each reflecting a state of one or more data in the set.  The paging mechanism includes a page-out element that stores data from a subset of the set to the associated data file.  During paging, that element responds to data in the subset which are associated with the atomic state -- as reflected by the atomic bit -- for storing to an associated status file on the disk attributes of the paged data.  Those signals can be, for example, the atomic bits themselves.

It  is  particularly suitable for use with the so called "mini" rolling mills which are small and flexible and  modular in design.
Patent CA-2081752-A1 (CA)
Inventor: HOOK CHRISTOPHER
IPC: G06K19/07
Filed: 1991-05-01
Abstract: An electronic identification system comprising a transmitter (5) for generating an electromagnetic excitation signal, one or more portable transponder (3) for storing variable identification data, and for transmitting an information signal containing the identification data upon entering the field. Transmission of the information signal is independent of the excitation signal in both time and frequency. A radio frequency receiver is provided for receiving the information signal and in response generating an output signal representing  the variable identification data contained in the information signal. THe system overcomes two principle disadvantages associated with existing systems: an excitation frequency can be selected for optimum performance given circumstances dictated by each application; an independent response channel can be selected according to the requirements of each installation or application, thereby allowing response signals to be transmitted by transponders at a frequency which differs from the frequency of an interfering signal.

Patent CA-2082431-A1 (CA)
Title: Method and apparatus for timing recovery in digital data communications systems
Inventor: CAPKUN EDWARD A
IPC: H04L7/04
Filed: 1991-05-23
Abstract: In apparatus for receiving digital data signals in a digital communication system; especially an Integrated Services Digital Network, timing recovery problems associated with erratic zero crossing when multiple terminals transmit to a common receiver are mitigated by detecting the rate of change of the digital data signal between tyro predetermined positions (C1, C2) and controlling sampling of the digital data signal in dependence upon the difference between such rate of change and a reference. The rate of change conveniently corresponds to the trailing "corner" of a framing pulse (F), i.e, the point at which the signal commences the transition from one polarity to the other. The "corner" is much more stable; i.e. less susceptible to variation due to multiple terminal effects, than the zero-crossing which follows it, since the zero crossing may vary relative to the "corner". The transition may be determined by sampling the digital data signal at two discrete positions and determining when the two resulting samples differ in amplitude by a predetermined amount. One of the two pulses (C1, C2), namely the one with the targer amplitude (1), may then be used for data recovery.

Title: Apparatus for the gasification of liquids
Inventor: TODD JOHN J
IPC: C02F3/20
Filed: 1992-05-01
Abstract: An apertured flexible membrane (10) extends over a domed support (11). A  central gas supply tube (50, 82) terminates in gas outlets (51) oriented to direct the gas to flow horizontally into the space (40) between the membrane and the support to inflate the membrane away from the support so that gas from the inflated space discharges through the apertures (60) as fine bubbles and such that when the gas supply ceases the membrane collapses back into area contact with the support to seal all the apertures. This reduces clogging. The aerator is useful in the aeration of sewage or waste water and in fish or eel farms.
