Patent CA-2252210-A1 (CA)
Inventor: MYER ROBERT EVAN
IPC: H03F1/32
Filed: 1998-10-29
Abstract: The present invention is a feed forward circuit and method for reducing distortion added to an output signal of the feed forward by its amplifiers without increasing the time delay in the main circuit path of the feed forward circuit. This is accomplished using a pre-distortion circuit to introduce a pre-distortion signal to the input signal of a correction amplifier. The pre-distortion signal being used to cancel a distortion signal that will be introduced by the correction amplifier. The pre-distortion signal has approximately the same frequency and amplitude as the distortion signal. The pre-distortion signal, however, has a phase difference of approximately 180° with respect to the distortion signal such that the pre-distortion signal and the distortion signal cancel each other when combined.

Title: A web cutting apparatus for use in a papermaking machine
Inventor: HILKER DIETER H
IPC: D21F7/04
Filed: 1999-01-25
Abstract: A water jet cutting apparatus for use in a papermaking machine has an elongated support beam that extends across the width of the web. The water jet cutting apparatus utilizes a free spinning hose wheel about which the water jet hose supplying water to a water jet nozzle is guided and stretched. The wheel is mounted for movement with a slower moving carriage along the beam adjacent a faster moving carriage carrying the water jet nozzle. The slower moving carriage moves along the beam at speeds which are one half the speeds at which the faster moving carriage moves across the beam. During this movement of the second slower moving carriage, the wheel reels the hose thereabout to provide a travelling intermediate support for the hose. The hose wheel supports the weight of the hose and maintains it in alignment with the faster moving carriage so that less strain and stress is placed on the hose and the ends of the hose connected to the water jet nozzle during movement of the water jet nozzle across the beam. The water jet cutting apparatus has a preferred application as a tip cutting device in a reel turn-- up application in a papermaking machine when two sets of faster and slower moving carriages are arranged for movement on opposite sides of the support beam to move towards each other in directions transverse to the web.

Filed: 1997-08-05
Abstract: Filtration apparatus has parallel filtration chambers (A, B, C, D) each of which has a filter screen and a cake of particulate material accumulated thereon for enhanced filtration. In normal use three chambers are in filtering operation, filtering fluid between an inflow conduit (100) and an outflow conduit (106); whilst one chamber, D as shown, is off-line. When another chamber, for example A, needs to have its filter screen de-caked it is taken out of operation and chamber D is brought into operation. After de-caking it is necessary to prepare the filter screen of chamber A for subsequent filtration and this is achieved by switching a fan (114) on, so that fluid filtered through chamber A is drawn through a recirculation conduit (108) and back into the inflow conduit (100). It cannot leave the apparatus until it has undergone effective filtration in one of the other filtration chambers. After an interval the filter screen in chamber A will have an adequate cake and is ready to be brought on-line.

Title: Power steering system
Inventor: KAJI HIROAKI
IPC: B62D5/06
Filed: 1997-08-13
Abstract: When a steering angle speed (V.theta.), a rate of change of a steering angle with respect to time is not higher than a predetermined stop threshold level (Vb) (YES at S10) with a motor current value (Im) within a motor stop range (.DELTA.I), which is determined on the basis of a no-load current value, for a predetermined period of time (YES's at S12 and S13), a motor is stopped (S14). Since the no-load current value is a value recorded when the steering torque is zero, the motor stop range corresponds to a range in which steering assistance is not required.  Namely, when both the steering angle speed (V.theta.) and steering torque are small, the steering assistance is regarded as unnecessary, and the motor is stopped.

IPC: H01R4/12
Filed: 1998-01-23
Abstract: A device for electrically interconnecting the wire leads (22) of various electronic elements (20) within a microminiature package (24). A non-conducting base (10) member having a plurality of electronic element barriers (14) and wire lead through-holes (15) is provided. The through-holes are generally located within the interior regions of the base element to minimize potentially detrimental filed interactions or capacitive coupling between the leads and the external package terminals.  During package assembly, the electronic elements are placed within recesses (16) created within the base member by the aforementioned barriers. These recesses and barriers align the elements and help maintain electrical separation and uniformity during manufacturing. The wire leads from two or more elements are interconnected by twisting them together and inserting them into one of the through-holes.  The leads are inserted into the through-holes such that they protrude below the bottom surface of the base element, thereby facilitating soldering (50) of all such connections in a single process step. This arrangement reduces manufacturing and labor costs and increases component and overall package reliability.

Patent CA-2286268-A1 (CA)
Title: Method and apparatus for noise reduction, particularly in hearing aids
Inventor: BRENNAN ROBERT
IPC: H04R25/00
Filed: 1998-04-16
Abstract: This invention describes a practical application of noise reduction in hearing aids. Although listening in noisy conditions is difficult for persons with normal hearing, hearing impaired individuals are at a considerable further disadvantage. Under light noise conditions, conventional hearing aids amplify the input signal sufficiently to overcome the hearing loss. For a typical sloping hearing loss where there is a loss in high frequency hearing sensitivity, the amount of boost (or gain) rises with frequency. Most frequently, the loss in sensitivity is only for low-level signals; high level signals are affective minimally or not at all. A compression hearing aid is able to compensate by automatically lowering the gain as the input signal level rises. This compression action is usually compromised under noisy conditions. In general, hearing aids are of lesser benefit under nosiy conditions since both noise and speech are boosted together when what is really required is a reduction of the noise relative to the speech. A noise reduction algorithm with the dual purpose of enhancing speech relative to noise and also providing a relatively clean signal for the compression circuitry is described.
