Patent CA-2015174-A1 (CA)
Title: Method and apparatus for thermal conversion of organic matter
Inventor: MEUSER WILLIAM E
IPC: B09B3/00
Filed: 1990-04-23
Abstract: ABSTRACT    A method and apparatus for the thermal conversion of organic waste materials includes a tank having a molten metal bath, preferably lead,   through which apertured containers are trans-ported by primary conveyer members in a plane intermediate two arrays of heating devices.  Buoyancy of the waste-filled contain-ers is resisted by abutment members within the tank while align-ment elements on the containers prevent the containers from becoming askew during their travel through the tank.  The abut-ment members may comprise fixed rails or secondary conveyor members spaced atop the primary conveyor members.   Agitation devices within the tank assist in maintaining maximum heat dis-tribution throughout the bath.   Produced hydrocarbons are col-lected by a main hood overlying the majority portion of the tank bath surface while separate shroud assemblies overlie other, individual isolated bath surfaces at the entrance and exit of the tank.   Inorganic and/or products not converted by the elevated temperature of the bath (over 650 degrees F), accumulate on the surface and are periodically removed by a skimmer apparatus, communicating with the exterior of the hood.  A continuous proc-ess is achieved by utilizing conveyors to deliver and retrieve the containers to and from the tank, respectively.

Patent CA-2017579-A1 (CA)
Title: Communication circuit fault detector
Inventor: YAMADA YOSHIKO
IPC: H04L69/40
Filed: 1990-05-25
Abstract: A communication circuit fault detector tests a communication circuit by using a sequence generator to generate a test signal, a memory circuit to temporarily store the test signal, and a multiplexer to multiplex the test signal and an input data signal into the communication circuit.  A timing generator drives the communication circuit at a rate higher than the normal communication rate, enabling the data signal and test signal to be sent through the communication circuit simultaneously.  A demultiplexer demultiplexes the output signal from the communication circuit into an output data signal and a returned test signal. A comparator compares the returned test signal with the test signal stored in the memory circuit and generates a result signal indicating whether they match.

Patent CA-2021363-A1 (CA)
IPC: A61B5/022
Filed: 1990-07-17
Abstract: The  invention is  a system and apparatus  for screening out blood pressure measurements that are inaccur-ate because of the presence of artifact while allowing such measurements to be utilized if they are accurate despite the presence of artifact.  The apparatus is a blood pres-sure monitor having a blood pressure cuff and air pump and valve pneumatically coupled to the cuff. A pressure transducer pneumatically coupled to the cuff generates a signal representative of the air pressure in the cuff and a signal corresponding to pulses in the cuff.  A processor responds to the transducer signal and energizes the air pump to inflate the cuff, periodically energizing the valve to reduce air pressure.  The processor in response to the measurements made calculates blood pressure parameters and compares them with recorded parameters to determine whether artifact has affected the accuracy of any recorded pres-sure.

Patent CA-2033988-A1 (CA)
Title: Boiler
Inventor: FULLEMANN JORG
IPC: F24H1/28
Filed: 1990-06-22
Abstract: Abstract The boiler has a heat-exchanger space (13) accommodated inside a water jacket (15).  Concentric to this is another water jacket (27) that extends at the rear of the boiler along approximately half the length of the first water jacket.  Inside the second water jacket is a concentric core (43).  There is a helical channel (54) with an outlet (33) for flue gas extending out of one intermediate space (53) and another helical channel (56) with another outlet (37) for flue gas extending out of another intermediate space (55).          In the vicinity of the mouths of the outlets (33 & 37) is a damper (39).  In the illustrated mid-position the flue gases can flow practically unimpeded out of both channels.  This corresponds to operation of the burner (11) at full load.          When the load is maximally reduced, the outlet (33) is closed off by the damper.  The temperature of the exhaust gas is the same in each case, however.  Thus, failure to attain the condensation point will be prevented in all parts of the boiler.

Abstract: The cellular mobile telephone apparatus comprises a radio unit having an antenna, and a telephone unit which is connected to the radio unit via a line and is formed of a main unit and handset.  To originate a call, a user dials the telephone number of an other party to be called.  When the dialing is detected, a calling tone indicating to the user that the call being originated is gen-erated from a speaker of the telephone unit.  To start speech communication, it is necessary to designate and capture a speech channel in the radio channel.  When the capture of the designated speech channel is detected, the calling tone is stopped.  After the communication, there are three types of terminating the call.  At the end of communication, the type of the termination is detected and the corresponding synthesized voice message is generated.

Title: Linear phase low pass filter
Inventor: BRAATHEN RUSSELL
IPC: H03H11/12
Filed: 1991-06-13
Abstract: ABSTRACT    An electrical signal filter composed of a pair of cascaded filter sections in which the group delays of the two filter sections are matched so that their non linear effects cancel in the passband, resulting in an overall linear phase.  In addition, the attenuation slope after the first null in one filter section's stopband response is complemented by the other filter's stopband attenuation.  This prevents the overall stopband attenuation from falling to extremely low values as with some filters, which, in turn, limits the time domain overshoot.  The passband group delay and stopband attenuation characteristics are controlled by appropriate selection of the passband ripple and filter order number parameters of the filter.  In a preferred embodiment, the two filter sections are of the elliptic and Chebyschev type.  The invention can be implemented as analog-component active filter circuit or as a digital filter.

Abstract: A groove cutter has a groove cutting edge that is inclined at a lead angle (K).  The groove cutting edge has a hollowed-out center region between end regions on both sides, and connection cutting edges provide transitions between the center region and the end regions.  The connection cutting edges have different lengths and are disposed with respect to one another at a flank angle (.delta.).          The groove cutter also has a cutting edge corner that leads in a groove cutting direction, along with a cutting edge corner that trails in the groove cutting direction.  One of the connection cutting edges is disposed adjacent to the leading cutting edge corner and forms an inclination angle (.alpha.) with respect to an adjacent end region cutting edge.          This angle of inclination (.alpha.) is greater than an oppositely directed inclination angle (.beta.) between the other connection cutting edge and another end region cutting edge, which trails in the groove cutting direction.

Abstract: A  track  roller  bearing  having  a floating sleeve between the inner  race  and  outer  race.   The floating sleeve has a self-lubricating  bearing material on its outer surface.  The coeffi-cient  of  friction  of  the  self-lubricating  bearing material increases  as  the  material is worn.  When the self-lubricating bearing  material  coefficient of friction exceeds the coeffici-ent  of  friction  of  the  floating  sleeve  inner surface, the floating  sleeve  will  rotate  with  the outer race until a new unworn  surface  of self-lubricating  bearing  material is pre-sented  to  the load area of the outer race.  This precessing of the  floating sleeve will continue until the entire surface area of   the   self-lubricating   bearing  material  is  worn,  thus extending the track roller bearing life.
