Title: Method and device for quantitatively determining the setting of an alternator
Inventor: RONDOT PASCALE
IPC: G01B13/12
Filed: 1995-11-08
Granted: 2005-02-22
Abstract: A method for quantitatively determining the setting of an alternator without removing or dismantling the alternator rotor, even when the width of the alternator air gap is no greater than 10 mm. The method uses a thin flat sensor with a recess on one side for receiving a piston. The sensor is inserted into the air gap and positioned in front of the wedge where the setting is to be determined, so that the piston is facing said wedge. A fluid is then injected into the sensor to urge the piston into contact with the wedge and press it thereagainst while the sensor is in engagement with the rotor. The pressure of the injected fluid, which is proportional to the force applied to the spring behind the wedge, is measured. Wedge movement when the pressure is exerted is also measured by means of a strain gauge attached to a flexible blade contacting the piston. The setting may thus be deduced from the measured force and movement. An apparatus for carrying out the method is also disclosed.

Title: Filter and hydraulic mixing assembly for water treatment
Inventor: WILFONG ROBERT W
IPC: B01D24/14
Filed: 1997-12-02
Granted: 2002-05-07
Abstract: A filter and hydraulic mixing assembly for a water treatment system. The assembly includes two circulation tubes disposed alongside a center tube. During a backwash cycle fluid is conveyed through the center tube to a housing member where it is discharged immediately below the open bottom ends of the two circulation tubes thereby conveying media from the surrounding tank upwards through the circulation tubes. A cap member is fitted over the upper ends of the circulation tubes within the tank and direct the media being discharged from the circulation tubes into a downward spiraling helical flow pattern which provides enhanced agitation and lifting of the media bed. Discrete filter segments are selectively attachable to the housing member and interchanging the discrete filter segments permits the total filter slot area of the assembly to be adjusted and also permits the filter slot size to be altered. The filter segments are color coded, with each separate filter size having a different corresponding color. The color coding scheme provides an efficient and effectivemechanism for preventing the inadvertent mixing of filter segments having different slot sizes.
