Abstract: A test system directed to apparatus for transmitting and receiving multiple telephone transmission signals over a single twisted pair (100). The system converts an analog signal from a local switching (112) station to an 80 ksymbols/sec signal for transmission over a twisted pair by a line card (104). A remote terminal (102) converts the 80 ksymbols/sec signal back into a con-ventional analog signal for use in conventional telephone (108), facsimile or other related equipment. The test equipment separ-ately tests the entire system, the line card portion of the system, the remote terminal portion of the system, and the twisted pair. An improved 2-to-4-wire hybrid coupling circuit (202) also is disclosed.

Abstract: A vacuum cleaner having a body with an inlet opening for dust laden air and an outlet.  An impeller is located between the inlet and the outlet.  A chamber within the body having at least one wall receives a perforate dust receptacle.  The chamber is located up-stream of the impeller.  An inlet passageway extends from the inlet opening into the chamber.  This passageway is directed so that when a perforate dust receptacle is in position in the chamber, the inlet passage has an outlet directed at a wall of the dust receptacle.  Dust laden air entering the receptacle is filtered to remove dust.  The dust laden air, forced against the wall by the impeller, acts to keep the wall free of dust accumulation.

Abstract: ABSTRACT OF THE DISCLOSURE       A calibration method and apparatus capable of being calibrated according to the method that allows a remote sensor to be transferred from analyzing instru-ment to analyzing instrument within a group of analyz-ing instruments without the need to recalibrate.  The device includes a separate memory capability associated with the sensor as well as each instrument while the method requires the use of an arbitrarily selected sensor to initially be transferred from instrument to instrument, while being subjected to the same calibra-tion standards in order to generate calibration data for entry into each instrument's memory.  With such data entered in the instruments' memories, any remote sensor, calibrated on any one instrument and having such calibration data stored in its own memory, can then readily be interconnected to any instrument of the group to immediately yield accurate results.

Filed: 1993-05-25
Abstract: A unique method and apparatus processes and validate Manchester-coded data transmitted on a communications channel and containing a synchronization word and a data word including a plurality of a data bits and coded according to a predetermined BCH error correcting code. Each data bits has a binary state determined by left half non-return-to zero (NRZ) bit sample and right half NRZ bit sample. The method for processing such data includes the steps of receiving a data work from the communications channel; checking the right half NRZ bit sample of the receive data word according to the predetermined error correcting code to detect the number of erroneous bit (810); error correcting the right half NRZ bit sample of the received data if the number of erroneous bits is less than a first predetermined number (814); comparing the left half NRZ bit sample to the error-correction right half NRZ bit samples of the received data word to determine the number of data bits that are in error (824); and discarding the receiver data word if it has more than a second predetermined number of data bits that are in error (830).The novel method may be used in processing data communications in any suitable system, such as, for example, data communications in cellular radio telephone systems.

Title: Process and apparatus for treating waste water in a dynamic, bio sequenced manner
Inventor: DESJARDINS GAETAN
IPC: C02F3/12
Filed: 1993-07-02
Abstract: ABSTRACT OF THE DISCLOSURE      A process for treating wastewater in a dynamic bio-sequenced manner in a single SBR reactor already filled with an activated sludge-mixed liquor.   In this process which is simple, fast and biologically and hydraulically "on going" and which allows one single SBR reactor to process typically twice as many batches of water per day as is presently processed within the existing SBR process, a, given amount of wastewater rapidly introduced into the SBR reactor below the clear water level to cause the level of the  wastewater  within  the  tank  to  raise  relatively uniformly and vertically and the supernatant clarified water to enter decantation pipes and be discharged out of the  reactor.   Then,  the  scum  floating on  top of  the wastewater is collected and discharged and the mixed liquor is mixed and aerated as long as necessary to achieve the required  treatment.   The mixed  liquor may  further  be stirred to bring the sludge totally in suspension within the liquor and a supplemental amount of wastewater added into the reactor to cause a corresponding amount of mixed liquor containing excess sludge to overflow.   Then the sludge in suspension is allowed to settle for a period of time sufficient to avoid solids to be carried out with the supernatant water when another given amount of wastewater is introduced into the reactor to repeat the above sequence of steps.  Also disclosed is a dynamic clarifier for use to carry out this process.
