Patent CA-2355754-A1 (CA)
Inventor: MORGANTI PIERO
IPC: F04B39/10
Filed: 2001-08-23
Abstract: A system for remote diagnosis of the state of wear of the suction and delivery valves of reciprocating compressors (20), comprising at least one piezoelectric seismic sensor (12), applied to each cylinder (14) of the compressor (20), which transforms the vibrations generated by the noise of the valves into an electric signal, from which, by means of appropriate amplification and filtering methods, the envelope of the resulting narrow band signal is obtained; the signal obtained is then digitised, and transmitted to a remote diagnostics centre (16), in order to be monitored.
Patent CA-2357460-A1 (CA)
Inventor: OXLEY LONNIE
IPC: F02M21/02
Filed: 2001-09-18
Abstract: An integrated fuel control unit for gas-operated internal combustion engines that includes a base on which a primary diaphragm is secured to define a primary fuel chamber. A primary fuel orifice is carried by the base, as is a primary control lever that is coupled to the primary diaphragm for controlling flow of fuel through the primary orifice as a function of inlet fuel pressure and engine demand. A secondary diaphragm is also secured to the base to define a secondary fuel chamber. A secondary orifice is carried by the base between the primary and secondary chambers, and a secondary control lever is coupled to the secondary diaphragm for controlling flow of fuel through the secondary orifice as a function of engine demand. A heat exchange section in the body receives engine coolant or engine oil for heat exchange with fuel so as to heat and vaporize the fuel between the primary and secondary chambers. A high-pressure fuel lock-off is carried by the body, and includes a solenoid coil mounted on the body and a solenoid plunger within the coil for selectively closing an end of the primary orifice remote from the primary control lever. A fuel inlet filter is carried by the body for filtering fuel prior to passage to the primary orifice and the lock-off. The solenoid plunger is normally urged by fuel inlet pressure and by a plunger spring to close the primary orifice, and is withdrawn from the primary orifice against the force of the spring by energization of the solenoid coil when the engine is operating. This feature helps ensure that fuel will not flow to the engine when the engine is not operating.

Title: Automated system for rating pipe segments in a water distribution system
Inventor: KIRWAN KEVIN B
IPC: G06Q50/06
Filed: 2001-09-27
Abstract: A computer-implemented process rates pipe segments in a water distribution system, the water distribution system including pipe segments and hydrants.  Information gathered from maintenance tasks and inspections performed on the pipe segments and hydrants within the water distribution system is stored in an electronic database. The information in the electronic database is analyzed for a specified period of time to determine the presence of water quality factors and service interruption factors. Points are assigned to the pipe segments based on the presence of the water quality factors and service interruption factors.  The pipe segments are rated based on the total points assigned to the pipe segments. The pipe segment ratings can be used for prioritizing the replacement of pipe segments in the water distribution system.

Abstract: Techniques to adjust the phase rotation of a modulated signal to compensate for the phase rotation introduced by circuit elements associated with the transmit signal path. The circuit elements can be located directly in, or operatively coupled to, the transmit signal path. A phase rotation corresponding to an operating state defined by the received control signal(s) is then determined, and the phase of the modulated signal is rotated by an amount related to the determined phase rotation. The phase rotation compensation can be performed at various locations along the transmit signal path by rotating either the data, the PN sequences used to spectrally spread the data, or the carrier signals used to modulate the data.
