Patent CA-2121266-C (CA)

Abstract: Wear-resistant titanium nitride coatings onto cast iron and other carbon-containing materials (18) is enhanced by means of a new surface preparation and deposition process. The conventional pre-deposition surface cleaning by Ar+ ion bombardment is replaced by a hydrogen-ion bombardment process which cleans the substrate surface (16) by chemical reaction with minimal sputtering and simultaneously removes graphite present on the cast iron surface.  Removal of the graphite significantly improves the wear resistance of titanium nitride, since the presence of graphite causes initiation of wear at those sites.  Hydrogen ion bombardment or electron bombardment may be used to heat the substrate to a chosen temperature.  Finally, titanium nitride is deposited by reactive sputtering with simultaneous bombardment of high-flux Ar+ ions from an independently generated dense plasma (10').  The resulting titanium nitride coating on cast iron evidences superior wear properties and adhesion compared to conventional reactive evaporation deposition techniques for titanium nitride.

A first handle shoulder abuts against the first housing shoulder when the locking handle is in a locking position, and a second handle shoulder is disposed adjacent to and overlapping with the second housing shoulder when the locking handle is in a locking position. Preferably, the housing defines a substantiallysmooth visible surface facing the one opening side, with the first housing shoulder recessed relative to the housing visible surface; and the locking handle includes a substantially smooth visible surface substantially surrounding the handle portion and facing the one opening side when the locking handle is in a locking position so that the visible surfaces cooperatively define a substantially smooth visible surface surrounding the handle portion when the locking handle is in a locking position.

Abstract: An interference cancellation system employing a polar vector modulator obtains a reference signal and a received signal.  The received signal has a desired signal component and an interfering signal component.  The reference and received signals as well as an auxiliary signal of known frequency and amplitude, are provided to a signal correlator circuit which compares and correlates the reference and received signals and generates an adjusted auxiliary signal which corresponds to the auxiliary signal adjusted in phase and amplitude.  A phase detector detects the difference in phase between the auxiliary signal and the adjusted auxiliary signal and generates a phase control signal in response.  Likewise, an amplitude detector measures the amplitude of the adjusted auxiliary signal and generates an amplitude control signal in response.  The phase and amplitude control signals and the reference signal are provided to a polar vector modulator having a 360° variable phase shifter and a variable attenuator coupled together in series, each of which has a low or negligible insertion loss.  The reference signal is amplitude and phase adjusted by the polar vector modulator to have substantially the same amplitude and to be 180° out of phase with the interfering signal component of the received signal.  The amplitude and phase adjusted reference signal is then summed with the received signal so that substantially only the desired signal component of the received signal remains.

Abstract: A method and apparatus for yarding logs by introducing slack is provided for use with a mono-cable system having a continuous loop of cable strung through a logging area along a path that the harvested timber is conveyed. The invention includes advancing the mono-cable system along the path of the mono-cable system until a length of cable not being used to secure a log is available. Slack is then created in the cable of the mono-cable system, after which the cable is transported to a log located on either side and distant from the path. The choker is then secured to the log, and the hook of the choker is secured to the cable. The slack of the cable is then eliminated, such that the secured log is retrieved from its felled position distant from the path to a position adjacent the path. The cable is then advanced such that the hook of the choker is caught on a stopper of the mono-cable system, and the log is moved along the path to a transport location from which the log is removed from the logging area. The use of slack in the mono-cable system provides superior selective harvesting of trees at a logging site, reduces the labor required for retrieving such logs, increases the capacity of the mono-cable system, and reduces dangers heretofore inherent in conventional mono-cable systems caused by the height and constant tension required in the cable, while retaining the advantages of mono-cable systems over conventional line systems.
