Patent CA-2022128-A1 (CA)
IPC: H04L27/00
Filed: 1990-07-27
Abstract: A subscriber unit for wireless communication with a base station in a wireless subscriber communication system includes a FIR chip, a DIF (digital intermediate frequency) chip, a single processor chip and a radio. The processorchip transcodes a digital voice input signal to provide digital input symbols; demodulates an output signal received from the base station to provide digital output symbols; and synthesizes a digital voice output signal from the digital output symbols. The FIR chip FIR filters the digital input symbols and generatestiming signals for timing the transcoding and synthesizing operations in the processor chip. The DIF chip digitally synthesizes a digital intermediate frequency signal by direct digital synthesis (DDS) and modulates the digital intermediate frequency signal with the filtered input symbols to provide a modulated intermediate frequency input signal. The radio further processes the modulated input signal for transmission to the base station.

Title: Process for soybean flavor control
Inventor: SAUB JERRY
IPC: A23L11/30
Filed: 1990-10-30
Abstract: PROCESS FOR SOYBEAN FLAVOR CONTROL                   ABSTRACT OF THE DISCLOSURE The natural beany flavor of soybeans, which is generally considered unpleasant and hence detrimental to the success of soybeans as a versatile foodstuff and source of nutrition, is removed by boiling the dehulled soybeans in an aqueous solution of the juice of guava, papaya, pineapple, apple, orange, or a combination of these.  Once the beany flavor is removed, the soybeans may be packaged and sold for consumption or processed into soybean-based food products such as soymilk or soy-based tofu.  A non-soybean flavor may be imparted to the soybeans or to food products derived therefrom by the use of flavoring agents at any stage subsequent to the soybean flavor removal. This includes soaking the soybeans in a marinade of the desired flavor, or adding the flavoring directly to the soymilk or to a coagulant solution in the preparation of tofu.  The strong beany flavor characteristic of the soybean may thus be replaced with delicate flavors and essentially any flavor.

Title: Procedure for the production of pulp
Inventor: VAHERI MARJA
IPC: D21C9/10
Filed: 1990-11-26
Abstract: (57) ABSTRACT OF DISCLOSURE             The invention relates to a procedure for the production of mechanical pulp from a fibrous product.  To reduce the refining energy, the fibrous product is subjected to an enzyme treatment in which an enzyme acts on the hemicellulose and/or cellu-lose in the fibrous product.  When hydro-lytic enzymes are used, it is preferable to use oxidation-reduction chemicals to adjust the redox potential to the optimum level characteristic of each hydrolytic enzyme.  In addition to reducing the refining energy consumption, the en-zyme treatment also improves the strength properties and the blue reflectance fac-tor of the pulp.

Inventor: MINDE TOR B
IPC: G10L19/10
Filed: 1990-03-09
Abstract: A method for positioning excitation pulses for a linear predictive coder (LPC) operating according to the multi-pulse principle, i.e. a number of such pulses are positioned at specific time points and with specific amplitude. The time points and the amplitudes are determined from the predictive parameters (ak) and the predictive residue signal (dk), by correlation between a speech representa-tive signal (y) and a composed synthesized signal (y). This can provide all possible time positions for the excitation pulses within a given frame interval. According to the proposed method, the possible time positions are divided into a number (nf) of phase positions and each phase- position is divided into a number of phases (f). These phases are vacant for the first excitation pulse. When this pulse has been positioned, the phase determined for this pulse is denied to the following excitation pulses until all pulses in a frame have been positioned.

Title: Burst time division multiplex interface for data link controller
Inventor: FARRELL JOSEPH K
IPC: H04L29/06
Filed: 1991-01-11
Abstract: BURST TIME DIVISION MULTIPLEX INTERFACE FOR       INTEGRATED DATA LINK CONTROLLER               ABSTRACT OF THE DISCLOSURE     Subject  burst  time  division  multiplex  interface connects  circuits  which perform  "layer  1  (L1)"  line control  functions  relative  to  a  data  communication network with devices which perform "Layer 2 (L2)" link control functions relative to the same network (L1 and L2 defined  by  OSI  Specifications  of  the  International Standards Organization). The interface is characterized by presentation of bursts of readiness indicating pulses from the L1 circuit to the L2 device during each basic time division multiplex time slot. The pulses indicate readiness  of the  circuits  for data bit  exchange,  and separate  time  overlapped bursts  are  sent  to  indicate readiness of the circuit to send and receive data bits. Each burst contains a varied number of pulses ranging from O to n (where n is greater than 2,  and in the disclosed embodiment equals 8). The bursts are positioned in a womdpw of time occupying a fraction of the slot interval close to the emd of each slot. This allows the L2 device to perform state swapping operations during the remainder of the slot to prepare for burst exchanges with different  network  channels  to  which  the  slots  are allocatable ant to be able to devote maximum processing time to performance of L2 tasks required relative to the channels.    The   channels    operate   under   various communication protocols (HDLC, LAP-D, clear/voice, etc.). Slot time spacings are variable by the L1 circuits to adjust to signalling conditions in the network.

Abstract: SUCTION BEAM                        ABSTRACT OF THE DISCLOSURE         A beam construction used in the area of single-draw of the drying wire (13) in a paper machine or the equivalent thereof is placed in proximity of the straight joint run of the drying wire (13) and the web (W) between the drying cylinder (10) and the leading cylinder (12) or roll on a sector (a) of the leading cylinder (12) or roll that is otherwise free from the drying wire (13).  The beam construction comprises a static closing-suction beam (20) with no blowing members.  The closing-suction beam (20) covers the drying wire (13) which runs from the drying cylinder (10) onto the subsequent leading cylinder (12) or roll, the web (N) being placed on the opposite face of said wire (13). At the inlet edges of the closing-suction beam (20) transverse seals (27,28) are placed against the drying wire (13) and the leading cylinder (12) as well as lateral seals (25, 25a) at the ends of the closing-suction beam (20).  These prevent the access of air into the spaces (14,15) between the closing-suction beam (20) and the drying wire (13) and the leading cylinder (12).  Negative pressure is produced in the latter spaces (14,15) and in the inlet nip (N+) between the leading cylinder (12) and the drying wire (13) by the intermediate of perforations (12c) in the mantle (12b) of the leading cylinder (12) out of the negative pressure prevailing inside the mantle (12b) of the leading cylinder (12).

Abstract: A  cooled  reactor  for  exothermic  catalytic conversion  of gaseous materials,  e.g.  for the  oxo synthesis, for the conversion of hydrogen and nitrogen to from ammonia and for the reaction of carbon oxides with hydrogen to form methanol, comprises a cylindrical pressure shell, distributor means for synthesis gas, at least one tube sheet and one or more catalyst beds provided with cooling tubes for the indirect cooling of reacting gas.  Each cooling tube consists of an outer tube provided with a heat exchanging outer wall; this outer tube surrounds and is coaxial with an inner tube and hence defines an annular space the inner wall of which is provided with perforations to direct the stream of  cooling  gas,  which  may consist  of  or  contain components of the synthesis gas, to the annular space and along the heat exchanging wall.  There is obtained a very rapid equalization of temperature differences in the catalyst bed, which causes an improved yield and hence makes  it possible to decrease the amount of catalyst for a given process.
