Patent CA-2260597-A1 (CA)
Inventor: DOLAN TROY D
IPC: B65G45/16
Filed: 1999-01-29
Abstract: Disclosed herein is an invention having to do with a method and apparatus for supporting and tensioning cleaning blades that are in contact with a moving conveyor belt. The method and apparatus disclosed herein comprise locating an elongate support bar under the return side of a conveyor belt and positioning its length transverse to the direction of travel of the conveyor belt. The support bar has mounted spatially along its length several individual spring loaded piston-cylinder assemblies.      Support plates are connected to the extensible end of each piston-cylinder assembly and cleaner blades are removably attached to the support plates. Each piston/cylinder assembly has an adjustable spring tensioning adjustment for the proper tensioning of each blade. The cleaner blades and piston-cylinder assemblies are arranged adjacently with one another along the length of the support bar, and the blade assemblies have side edges preferably with tongue and groove connections so that each adjacent cleaning blade has a sliding engagement with one another. On each end of the transverse support bar is located a pneumatic/hydraulic, extension/retraction mechanism that connects between the transverse support bar and a support bracket for firmly anchoring the scraper blade assembly to a foundation.      Shock absorbent means are mounted between the transverse support bar and the pneumatic/hydraulic, extension/retraction mechanism.      The invention contemplates the method of locating the scraper blade assembly on a foundation so that the scraper blade edges are located approximately 1/4 to 1/2 inch below the return side of the conveyor belt. The pneumatic/hydraulic, extension/retraction mechanism is then extended so that the blades come in contact with the belt. As wear occurs on the individual blades or as the conveyor belt becomes curved more in the middle, the blades will then be automatically adjusted by the piston cylinders so as to press against the belt in a uniform manner. When it is necessary to change the blades, the extension/retraction device may be retracted and the piston cylinders will be retracted from contact with the belt.

Title: Apparatus and method for restoring fiber optic communications network connections
Inventor: NAGARAJ KESAVAMURTNY
IPC: H04B10/00
Filed: 1998-07-08
Abstract: A system and method for connecting traffic along a communications network are accomplished by rerouting traffic upon the detection of a fault condition along a primary connection path. Signals are divided into different wavelength regions labelled red and blue, respectively. The wavelength bands between transmit and receive channels are alternated between red and blue band regions and then combined, multiplexed or "bundled" together by a wideband wavelength division multiplexer in a single non wavelength specific transmission medium for connection to a single unidirectional Optical Cross Connect System (OCCS) port. Additionally, the receiving end of a single medium is connected to a wavelength division multiplexer which unbundles the combined red and blue band signals upon reception.

Patent CA-2281423-A1 (CA)
Inventor: WOLSTENHOLME PAUL P
IPC: B65G3/02
Filed: 1999-09-03
Abstract: A method of forming a grain pile by pushing grain into a buried insertion point. A screw conveyor is disclosed for carrying grain at ground level from a receiving point to the buried insertion point. The screw conveyor creates a pile core at the insertion point and forcibly enlarges the pile core into a large pile against forces of natural resistance.  The method is disclosed as being useful in contemporary grain storage facilities where it reduces exposure of the cover to wind damage and in traditional storage facilities where it reduces the risk of explosion, all at reduced cost and with reduced grain damage. Piles as large as 2,000,000 bushels can be formed by a conveyor having a drive motor of less than 50 horsepower. Grains of different properties may be formed into a pile and become blended as a consequence thereof.

Title: Muscle function assessment apparatus and method
Inventor: RICHARDSON CAROLYN ANNE
IPC: A61B5/22
Filed: 1998-05-08
Abstract: A method and apparatus for assessing the function of deep joint stabilising muscles. Superficial muscles are monitored using an EMG (3) during performance of an activity known to require recruitment, primarily, of deep stabilising muscles when performed correctly. If the deep muscle functions adequately, there is little activity of the superficial muscles. Conversely, if the deep muscle function is inadequate, the superficial muscle activity is increased. Monitoring of the superficial muscles may be combined with monitoring of the deep joint stabilising muscle using ultrasound imaging (12) and/or pressure biofeedback. The apparatus includes an EMG unit (3) ultrasound unit, pressure biofeedback unit (16) and vitalograph (9), in combination with a computer (5) programmed to analyse data from them and give an indication of function.

Patent CA-2292905-A1 (CA)
Title: Method of and arrangement for electrochemical machining
Inventor: KUCENKO VIKTOR N
IPC: B23H3/02
Filed: 1999-03-29
Abstract: The invention relates to a method of electrochemically machining an electrically conductive workpiece in an electrolyte by applying electrical pulses between the workpiece and an electrically conductive electrode, one or more machining pulses (MP) alternating with voltage pulses (PP) for depositing passivation layers on the workpiece. The amplitude of the voltage pulses is adjusted during an adjustment procedure in which the amplitude of the voltage pulses is increased gradually from zero to the voltage at which the workpiece starts to dissolve in the electrolyte. After each voltage increase the resistance of the gap between the electrode and the workpiece is measured. The voltage value for the highest gap resistance is stored in a memory and used during further machining. The time span of the voltage pulses may be divided into time slices (Dt) and for each time slice the voltage is adjusted for maximum gap resistance during that time slice.

Patent CA-2302176-A1 (CA)
Title: A device and method for recommending dynamically preferred speeds for machining
Inventor: STERN ELLIOT L
IPC: B23Q15/08
Filed: 1998-09-08
Abstract: A hand-held, portable device recommends dynamically preferred speeds for stabilizing or reducing undesirable vibration such as chatter in a machining process. The device may be applied to machining processes such as turning, boring, milling and drilling which exhibit a relative rotational motion between the cutting tool and workpiece. The device measures in a safe, non-contact manner via a microphone the dominant audio signal component of the sound pressure emanating from the machining processes. Without prior knowledge of the machining process parameters or the dynamic characteristics of the machine tool or workpiece, the audio signal is conditioned and processed to determine the frequency component levels.      The rotational speeds which are more likely to lead to a stable machining process are calculated based on the number of teeth on the cutting tool and the identified dominant frequency of vibration. The dynamically preferred speeds are displayed as recommendations to the process operator or machinist.
