Patent CA-2130871-C (CA)
Inventor: ALDER JOHN M
IPC: H03L7/22
Filed: 1994-08-25
Granted: 1999-09-28
Abstract: A phase-locked loop circuit with holdover. mode is formed utilizing a primary and secondary phase-locked loop circuits. Each loop circuit comprises a phase detector, loop filter, VCXO and frequency divider. The secondary loop is configured such that its output is very stable.      The primary loop is phase-locked on a received reference clock signal and the second loop is phase locked on the output of the primary loop. The scaled output of the secondary loop being parallel to the reference clock signal. If the incoming reference signal is interrupted or lost the circuit is switched to a holdover mode where the input of the primary loop is switched to the stable scaled output of the secondary loop. In holdover mode, the output, of the primary loop is phase-locked to the stable output of the secondary loop. When the reference clock signal is reestablished, the input of the primary loop is switched back to the reference clock signal.

Title: Cam drive mechanism
Inventor: DUNCAN WAYNE C
IPC: B25B13/46
Filed: 1994-10-18
Granted: 1998-02-24
Abstract: A reversible gearless drive mechanism for a socket wrench comprises a driven member having an upper centering support flange and a lower centering support race, between which is a cam-like area around the circumference defining three symmetrically opposite bi-directional ramps.   The driven member is axially centered within a drive member defining a round cylindrical bore, between which each bi-directional ramp forms one right hand wedge and one left hand wedge.  Between  each  two  bi-directional  ramps  are two cylindrical rollers held apart into their respective left hand and right hand wedges by a leaf spring. The cammed circumference of the driven member does not contact the inner circumference of the bore for centering support permitting the use of larger diameter  rollers relative to the diameter of the bore in which the mechanism is centered. The larger diameter rollers combined with the pressure of the leaf springs provide adequate friction drag to hold the driven member stationary while a thumb operated rotary selector switch overcomes a spring and pin detente to unwedge either the three left hand or the three right hand rollers  to change the direction of drive.  This permits a change in drive directions with only one available hand. The larger diameter rollers also provide a more positive lock for the drive and are more tolerant to small particles and imperfections caused from wear or contamination.

Patent CA-2157661-C (CA)
Title: Method and system for demodulation of downlink cdma signals
Inventor: DENT PAUL W
IPC: H04B7/08
Filed: 1995-01-27
Granted: 2005-05-17
Abstract: Demodulation of a CDMA downlink signal is performed by filtering correlations of the received signal with a known signature sequence. Unlike the conventional Rake receiver, the filtering is not necessarily a FIR filter (102) with coefficients equal to the conjugates of channel tap estimates (105). Instead, the present invention filters in such a way as to maximize the output signal-to-noise ratio, accounting for the fact that part of the noise comes from the same base station as the signal, so that it is colored by the same channel as the signal. This is accomplished by replacing the RAKE FIR (102) combining filter with a more general filter such as IIR filter (202) or FIR filter (402).

Title: Extended life brake cylinder holder
Inventor: HOFFNER JAMES C
IPC: F16D65/28
Filed: 1996-09-13
Granted: 2000-01-04
Abstract: A push rod holder for use with a brake cylinder of a railroad vehicle is disclosed.  The push rod holder includes an annular outer metal member and an annular inner elastomeric member.          The annular inner elastomeric member is molded to an interior surface of the annular outer metal member.  The push rod holder defines at least one set screw throughhole and a pair of aligned holder pin throughholes.  Each of the throughholes is oriented perpendicularly to a longitudinal axis of the push rod holder.  The brake cylinder includes a hollow piston rod and a push rod assembly inserted therein.   The push rod holder concentrically fits onto the hollow piston rod.  The annular inner elastomeric member assures that the push rod holder fits snugly about the hollow piston rod.  At least one set screw is used to attach the push rod holder to the hollow piston rod via the at least one set screw throughhole.  A holder pin device is used to lock the push rod holder to the hollow piston rod and the push rod assembly contained therein.   The annular inner elastomeric  member  dampens  vibrations  encountered  at  the junction of the push rod holder, hollow piston rod and push rod assembly.  The push rod holder thus reduces the likelihood of damage  occurring  to  these  components  and  prolongs  the operational life of the brake cylinder.
