Patent CA-2255525-A1 (CA)
Title: Low noise hydraulic power unit for an auto hoist lift
Inventor: HOBSON NICHOLAS M
IPC: F15B11/04
Filed: 1998-12-07
Abstract: A hydraulic power unit for an auto-hoist lift having improved noise characteristics and a more compact design. A motor and pump driving the power unit are located inside a hydraulic fluid reservoir to thereby reduce the amount of noise reaching the immediate vicinity of the power unit. The motor and pump are submerged in the hydraulic fluid to advantageously utilize the hydraulic fluid to cool the motor. The power unit may further incorporate a delay valve for reducing the start-up torque load on the motor, thereby allowing the motor to be sized for normal operating requirements rather than oversized for start-up requirements.

Patent CA-2264030-A1 (CA)
Title: Improved annular flow monitoring apparatus
Inventor: ALLAN JOSEPH CALDERHEAD
IPC: G01F1/44
Filed: 1997-09-02
Abstract: An improved annular flow monitoring apparatus is described which improves flow monitoring accuracy by taking account of scale thickness when calculating flowrate measurement. This is achieved, in one aspect of the invention, by providing a flow restrictor insert (14) into the bore of a conduit or pipe (12) with the flow restrictor insert being arranged so as to create an annular flowpath around the insert, the flow restrictor insert having at least two substantially co-axial portions (36, 40) of different diameters with sufficient pressure monitoring stations (P1, P2, P3) being provided so as to allow the calculation of at least two pressure differentials. This can be implemented by providing three absolute pressure gauges which may be located at three appropriate locations (P1, P2, P3) in the bore of a carrier or by using two differential sensors connected to the monitoring stations to calculate pressure differentials from the three bores. The three pressure monitoring bores and two differential pressure sensors (43, 45) may be located within the flow restrictor insert (14), and the pressure sensors being located in respective co-axial portions. In another embodiment a multiple venturi flowmeter (5) is used to calculate scale deposition with the same type and number of measurements. Using standard fluid mechanics analysis, a mathematical model is derived which computes gross flowrate from the three pressure measurements (non-differential) in a scaling environment. For each embodiment, a value of scale thickness is a byproduct of the calculation and this is used as the basis for a downhole scale indicator.

A portion (40) of the DAO product stream (16) is heated (41) to produce a stream (42) of heated deasphalted oil, a portion (43) of which indirectly heats the two primary liquid streams (14 and 15).

Title: Adaptive pre-equalization apparatus for correcting linear distortion of a non-ideal data transmission system
Inventor: TWITCHELL EDWIN RAY
IPC: H04N7/12
Filed: 1998-07-23
Abstract: An apparatus (10) for compensating a linear distorting action to an information signal within a transmission system (12). Within the system (12), an information signal proceeds to a transmitter (24) that has an amplifier (62). A sample signal is coupled-off from the transmitter (34). The linear distorting action of the system (12) includes shifting of at least one aspect of the signal away from its intended value. A linear pre-equalizer (54), located along a signal stream of the information signal to the transmitter (34), pre-equalizes the information signal. An adaptive equalization determination (70), connected to receive the sample signal and the information signal outside of the signal stream to the transmitter (34), determines an amount of pre-equalization required from the linear pre-equalizer (54) to compensate the linear distorting action of the system (12). The pre-equalization by the linear pre-equalizer (54) is modified in response to the determination by the adaptive equalization determination (70).
