Patent CA-2076846-A1 (CA)
Inventor: MACDONALD DANIEL W
IPC: G01N21/47
Filed: 1992-08-25
Abstract: The Infra-Red Densitometer (IRD) readings of developed toner patches in a tri-level imaging apparatus are compared to target values stored in Non-Volitale Memory (NVM) and are also compared to the previous IRD reading. Toner dispensing decisions (i.e. addition or reduction) are based on both comparisons. In this manner, not only are IRD readings examined as to how far the reading is from the target, they are examined as to current trend (i.e. whether the reading is moving away from or toward the target).

Title: Offset frequency converter for phase/ amplitude data measurement receivers
Inventor: CURRIE CHARLES H
IPC: H04B1/26
Filed: 1991-03-07
Abstract: OFFSET FREQUENCY CONVERTER FOR PHASE/AMPLITUDE DATA MEASUREMENT RECEIVERS            ABSTRACT     An offset frequency converter (10) for the intermediate frequency (IF) stages of a multi-channel radio frequency (RF) phase/amplitude measurement receiver (8).  The converter allows use of noncoherent transmitter and receiver local oscillator sources which utilize digital frequency synthesizers and enables harmonic mixing to be employed.  The converter samples an incoming first intermediate frequency signal IF1 in a reference channel (38b).  The IF1 sample is then upconverted to a higher frequency, filtered and downconverted to an IF1 + IF2 signal offset from the IF1 sample by a lower second intermediate frequency IF2.  The added frequency offset IF2 is derived from a time stabilized source independent of the transmitter but coherent with the receiver LO.  The mixed IF1 + IF2 signal is heterodyned with signals in both the signal channel (38a) from the antenna under test and the reference channel to obtain coherent outputs at IF2 which differ by phase and magnitude corresponding to the characteristics of the antenna under test.

Title: Disc cutter
Inventor: FRIANT JAMES E
IPC: E21B10/12
Filed: 1993-11-03
Abstract: DISC CUTTER          ABSTRACT            An  improved disc type rolling rock cutter,  and novel cutterheads employing such cutters.  A rock cutter with an improved,  simplified structure,  with compact bearing,  and smooth,  rounded blade shape is disclosed.   The design incorporates a cutter ring, bearing, and seal into a single cutter ring assembly.   The cutter may be assembled and disassembled for rework by a single worker with simple hand tools.  Replacement of worn out cutter rings is done quickly and easily by removing the old ring assembly and then sliding a new ring, bearing, and seal assembly on to the cutter shaft.  This simplified assembly is achieved by using a comparatively large shaft which is normally in the range of 40-50% of the ring diameter.   The shaft design is sufficiently robust to permit a cantilever mount of the cutter.  The unique configuration allows 30,000 lbs. or more thrust to be applied to a 5 inch diameter miniature disc.          This capacity permits single disc cutter technology to be applied to smaller bits or cutterheads than previously possible.  Also, a unique method of shaping and installing hard metal inserts improves cutting efficiency over the life of the cutter, and increases wear life in highly abrasive conditions.

Abstract: DOUBLE-WALL COMPOSITE PIPE AND COUPLING STRUCTURE ASSEMBLY AND METHOD AND APPARATUS FOR MAKING SAME                         ABSTRACT      A double-wall composite pipe comprises a permeable annulus structure separating impermeable inner and outer walls.  The permeable annulus structure has micro-fractures formed therein that function to reduce the flow rate and pressure of fluids leaking through the inner wall to thus inhibit fluid leakage.  The annulus structure resists the stresses produced by internal fluid pressures and other service loads.  The inner and outer walls will remain permanently impermeable while the pipe annulus structure undergoes stress-induced dimensional changes.   A coupler assembly mechanically connects each longitudinally adjacent pair of pipes together and comprises two semi-cylindrical half-couplers,  a  compressible seal ring, a cylindrical retaining sleeve, and a flexible boot that encloses and seals the assembled half-couplers.  A leak detecting sensor may be located at the coupler assembly.  A preferred method and apparatus for making the pipe and coupler assembly are also taught.
