Patent CA-2347942-C (CA)
Title: Rotary shaft brake
Inventor: SARUWATARI MINORU
IPC: F16D65/28
Filed: 2001-05-22
Granted: 2006-11-21
Abstract: A relatively simple hydraulically operated disc brake mechanism for drive systems which store torsion by reason of being under torque is disclosed. Certain drive systems such as the drive strings for deep well submersible pumps store considerable torsion due to torque and elasticity. Such torsion must be controllably released if drive power is interrupted. The disc brake mechanism includes a housing that defines a reservoir for lubricating oil for the bearings of a shaft that drives a bi-directional hydraulic pump. When the shaft turns in an operating direction, the pump conveys the lubricating oil in a closed circuit by way of a control manifold through the brake mechanism and back to the reservoir, without activating the brake mechanism. This flushes the complete lubricating oil circuit including the control manifold and the brake mechanism to prevent accumulation of gas pockets therein at locations of little or no fluid flow. If normal operation is interrupted and the reactive torque in the system is released, the bi-directional pump forces oil through the control manifold to a disc brake caliper of the brake mechanism while controlling oil flow through the brake mechanism, which activates the brake mechanism to brake a disc rotor attached to the shaft. The faster the shaft turns as it releases reactive torque, the more braking force applied. As torsion is released, pump speed drops and brake force is correspondingly reduced until all torsion is released from the drive string permitting safe handling and soft restart of the drive string. The advantage is much improved safety and a self-regulating brake mechanism that handles power interruptions without manual intervention and is no longer prone to brake fade.

Abstract: A system and method for signal peak reduction in a multiple carrier communication system where the individual carriers are produced from input symbols that are filtered to reduce individual carrier bandwidths, offset in frequency, and combined into an output signal. A multiple carrier peak reduction unit (12) is provided which modifies the input carrier symbols so that the combined output signal does not exceed a predetermined peak limit value. The multiple carrier peak reduction unit includes filter predictors (54) that predict the effect of each channel filter (30) on that carriers input symbols by using filter coefficient values corresponding to the impulse response function of each filter (30). The filter predictor outputs are then phase shifted, in correspondence to frequency offsets provided for in multiple carrier signal generation, and combined to produce a prediction of the combined signal output which is then processed to determine the corrections required to the individual channel symbol inputs.
