Patent CA-2301977-C (CA)

Abstract: A control system is provided for a tracked vehicle drive/steering system having an engine driven hydraulic steering pump which drives a hydraulic steering motor.  The steering pump is responsive to steering control signals representing a status of an operator manipulated steering wheel. The steering motor provides an input to a differential track drive mechanism which responds to manipulation of the steering wheel and drives left and right tracks to turn the vehicle. The control system includes a control unit which receives signals from an engine speed sensor, a steering motor rotation speed and direction sensor, and the steering control signals. The control unit, when the steering control signals indicate that the steering wheel is turned in a direction opposite to a direction of rotation of the steering motor, generating and saving a first ratio value representing a ratio of the motor speed to the pump speed. Then, if the steering control signal is unchanged after a certain time duration, the control unit generates and saves a second ratio value representing a later ratio of the motor speed to the pump speed. The control unit then calculates a difference value representing a difference between the first and second ratio values, and generates a fault signal if the difference value has a magnitude which is less than a predetermined magnitude.  Thus, the control system generates a fault signal when the sensed signals indicate that the steering pump swashplate position is not changing as it should in response to changes in steering wheel position.

Abstract: L'invention concerne un broyeur qui comporte un conteneur rotatif (40) dans lequel sont amenés des matériaux particulaires. Le conteneur tourne à une vitesse supérieure à la vitesse critique pour former une couche qui est maintenue sous une pression élevée contre la surface intérieure du conteneur. Des disques de cisaillement (58) fixés à l'intérieur du conteneur induisent le cisaillement de la couche pour favoriser la fracture particulaire, par cisaillement et abrasion dans la couche sous pression. Les matériaux finement broyés se déplacent dans le sens axial vers l'extrémité de décharge du conteneur (64). Selon un mode de réalisation de l'invention, le conteneur tourne à une vitesse suffisante pour former une série de zones solidifiées (70) alternant avec des zones brassées (72) près des disques de cisaillement non rotatifs (58). Ces zones solidifiées agissent comme des disques solides tournant avec le conteneur.

Abstract: A Web-based computer system is provided with software for processing of inbound messages originating from a back office system. The computer system or web-based application may be operated to maintain the consistency of the information on both systems. A  method of operating the computer system and application is also provided. The method, system and application accommodate use of multiple inbound queue server processes, multiple ports for sending messages from the back office system and multi-threaded processing in the web-based application system. The various inbound messages received by the web-based application system are processed in proper time sequence. Every document created by the back office system is identified with a unique primary key. The primary key identifies the type of document and the document number corresponding to the particular document. The document and a timestamp identifying the date and time of the document's creations are stored in the back office database. The web-based application system receives an inbound message including the document information from the back office system. Upon receipt, the web based application system searches a database listing primary key information of earlier received messages and compares the primary key information of the inbound message. If the primary key of the inbound message matches a stored primary key entry, the timestamps of the two messages are compared. The message having the later timestamp is identified as the most current version and is recorded in the web-based application database.

Abstract: A system is provided that monitors at the wellsite injection of additives into formation fluids recovered through well bores and controls the supply of such additives from remote locations. A pump supplies the selected additive from a source at the wellsite into the wellbore via a suitable supply line. A flow meter in the supply line measures the flow rate of the additive through the supply line and generates signals representative of the flow rate. A controller at the wellsite determines the flow rate from the flow meter signals and in response thereto controls the pump to control the flow rate of the additive to the well. The wellsite controller interfaces with a suitable two-way communication link and transmits signals and data representative of the flow rate and other parameters to a second remote controller. The remote controller transmits command signals to the wellsite controller representative of any change desired for the flow rate. The wellsite controller is microprocessor based and may be programmed at the wellsite or by the remote controller to adjust the flow rate. The system of the present invention may be configured for multiple wells, with each well having a separate wellsite controller or a common wellsite controller.

Abstract: An acoustic array includes amplifiers (124) and sensor subarrays (112), both of which are placed along rungs that connect a return distribution bus (144) with both a signal distribution bus (116) and a pump distribution bus (132). By placing the amplifiers (124) along the rungs, separate buses can be used for distributing the optical signal and th e pump energy for the amplifiers (124), thereby facilitating the use of standardized couplers (121-123; 136-139; 140-143). Time division multiplexed sensor subarrays (230) are advantageously connected to unique combinations of laser signal sources (200-203) and signal return buses (270-274), in which the laser signal sources (200-203) generate different optical wavelengths (.lambda.1, .lambda.2, .lambda.3, .lambda.4) that are multiplexed on the signal return buses (270-274). Optica l sources include intensity modulators (910) on either side of an amplifier (920) to eliminate extraneous noise between optical pulses. In addition, amplified spontaneous emission (ASE) filters (940) may be advantageously used to reduc e optical noise at wavelengths other than those of interest.

Granted: 2005-11-22
Abstract: The present invention relates to a controller (11), a cabin pressure control system (10) and a method for controlling pressure in a cabin (30), especially an aircraft cabin. In accordance with the invention the controller (11) comprises a channel (15; 16) and a pressure differential safety function (22). The channel (15; 16) calculates a first output signal (40) for actuating an overflow valve (17) in a closed loop control based on the pressure differential between the cabin (30) and the atmosphere and additional critical parameters. The safety function (22) calculates a second output signal (41) based only on the pressure differential.      The two output signals (40, 41) are compared, and the second output signal (41) is selected, if said first output signal (40) is found inaccurate. The safety function (22) assures operation of the outflow valve (17) even if the channel (15; 16) is out of function. Accordingly, the number of additional safety valves (18) may be reduced so that the weight of the system (10) is minimized. A manual control panel (26) is provided for backup.
