Patent CA-2146393-A1 (CA)
Inventor: MEEK QUENTIN J
IPC: H04B3/23
Filed: 1995-04-05
Abstract: In an echo cancelling arrangement, an estimated echo signal is produced by an adaptive filter from a receive path signal and is subtracted from an incoming transmit path signal to produce an outgoing transmit path signal, to compensate for ERL  (echo return loss) via a hybrid circuit. Short-term averages of signal levels on the receive path arid the incoming and outgoing transmit paths are produced by exponential averaging. An ERLE (echo return loss enhancement) due to the subtraction of the estimated echo signal is calculated from the incoming and outgoing transmit path averages and, when this exceeds a threshold value, enables averaging of a ratio of average levels on the receive path to average levels on the incoming transmit path. The resulting long-term average constitutes a determination of the actual ERL.

Title: Method for recovering particulate and scavenging formaldehyde
Inventor: SORENSON BLAINE F
IPC: C02F1/44
Filed: 1993-08-27
Abstract: A thin film mem-brane filtration system (50) recovers particulate from the waste water stream (66) of a wood panel fabrica-tion process to a desired concentration of approxi-mately 30-50 % solid by weight. The high concen-tration level enables im-proved transport or dispo-sal. Rather than discard the concentrate, however, the concentrate is added into subsequent wood pan-el "particle board" batches at a rate of approximately 0.5 to 0.65 gallons per 1000 pounds of wood pro-duct. The concentrate re-duces press time, serves as a scavenger for tying up formaldehyde and serves as a resin extender for strengthening internal bonds of fabricated pan-els. The membranes (54) capture the particulate into an accumulated concentrate, while passing permeate output to a recycle water stream (80).

Title: Method for manufacturing consecutively opened bag and bagging system
Inventor: TSENG BEN
IPC: A47F13/08
Filed: 1995-09-20
Abstract: A method for manufacturing automatic consecutively opened thermoplastic T-shirt bags  for dispensing from a conventional supporting  rack.   The method  involves  providing a continuous flattened tube of thermoplastic film and applying adhesive solution using a printing press to form adhesion regions on the outside of the tube.  The adhesive solution can be applied using a flexo or gravure printing process.  The method then involves forming side gussets in the tube and making traverse seals in the tube, thereby dividing the tube into pillowcases.  The pillowcases are separated at the seals to form a series of end-sealed gussetted pillowcases which are stacked to form a bag pack.  Next, the bag pack is cut along a bag-mouth contour to from a plurality of T-shirt bags.  The bag-mouth contour forms a set of laterally spaced handles each having a receiving aperture for a conventional support rod of a dispensing rack, a central tab having a mounting aperture, and an open mouth region.   The adhesion regions are optimally located below the receiving apertures and above the lowest point of the bag-mouth contour.   Finally,  slight pressure is applied to the proximate area of the adhesion regions of each bag in the bag pack to  form a disengageable  link between consecutive  bags.   The invention also relates to the T-shirt bags and the bag packs produced from this method.

Title: Digital demodulator with frequency correction
Inventor: ORTEGA RODRIGUEZ FERNANDO
IPC: H04L27/233
Filed: 1995-09-28
Abstract: Specially for application in space communications where the movements of the satellite produce shifts in the carrier frequency due to the Doppler effect and where the received signal is very weak and masked by noise. The input signal (Xi) is mixed in a first multiplier (M1) with a local oscillator signal (XOL) coming from a first voltage-controlled oscillator (VCO), obtaining thereby an intermediate frequency signal (XFI). This voltage-controlled oscillator (VCO) receives a frequency error signal (FD) to compensate the variations in the carrier of the input signal (Xi).      The frequency error signal (FD) is also applied to a numerically controlled oscillator (NCO), whose output signal is mixed with the intermediate frequency signal in order to reinsert the variations in the input signal carrier (Xi) in the reception path and have these available subsequently to obtain the frequency error signal (FD).

Title: Data phase alignment circuitry
Inventor: BUCKNER WADE B
IPC: H04L7/02
Filed: 1994-11-29
Abstract: A data phase alignment circuit (34) is provided to align incoming plesiochronousdata with a known clock phase. Multiple phases of a clock signal are provided to a data capture circuit (40), which captures the incoming plesiochronous data with at least one of the clock phases. A data transition decoder (44) then determines the time of data transition with respect to the multiple phases of the clock. The captured data is then realigned with a selected phase of the multiple clock phases by a data retimer circuit (50) and provided as the output (64). The resultant data is therefore aligned with a known phase of the clock signal and is no longer plesiochronous with respect to the clock signal. Data shifting due to data jitter, drift and wander may also be corrected with a slip buffer (38).
