Title: Method for determining physical properties
Inventor: BELCHAMBER RONALD MALCOLM
IPC: B02C25/00
Filed: 1988-09-19
Abstract: A method for the determination of the value of a property of the material within a mill during the comminution of solid material within the mill comprises the steps of:   (a) detecting the noise intensity of milling by means of an analogue electrical signal, the intensity of which is proportional to the intensity of the noise in the audio frequency range, converting the analogue signal to a digital signal, (c) passing the digital signal through a digital band-pass filter to select at least two frequency bands, and (d) analysing the data from the bands by means of a multivariate statistical technique to obtain the value of the property. The method is particularly suitable for determining the particle size distribution of material being ground in a ball mill. p

Title: A purge strategy for a hybrid electric vehicle
Inventor: ROBICHAUX JERRY D
IPC: B60W20/00
Filed: 2001-12-14
Granted: 2004-09-15
Abstract: The present invention provides a method and system for purging a vapor canister in a Hybrid Electric Vehicle during vehicle idle conditions. The present invention first determines whether purging is necessary by measuring fuel tank pressure and the time since the last purge. If either of these elements exceeds a calibratable threshold, the controller determines that the engine needs to be on and that purging must occur. An electronic throttle controller can also be used to command the throttle plate to low positions to increase intake manifold vacuum while purging. This allows for very rapid ingestion of the fuel vapor without risk of engine stalls, if used in an HEV where the engine speed is controlled by an electric motor. Upon completion of the purging process, the engine is shut "off" and the vehicle is returned to its normal idle conditions.
