  • Method of detecting tire mold bladder leakage by smell
    Patent number: 10603858
    Abstract: A method of detecting tire mold (10) bladder (14) leakage is provided that includes placing an uncured tire (12) into a mold (10), and inflating a bladder (14), that has a fluid (22), within the mold. Sufficient heat and pressure are applied to at least partially cure the tire when the uncured tire is in the mold (10). The mold (10) is opened and electronic smelling is conducted on the at least partially cured tire (12). The electronic smelling is performed in order to determine whether the bladder (14) is leaking the fluid (22).
    Type: Grant

  • Method and apparatus to suppress electrical noise in a rotor assembly for an electrical machine
    Patent number: 7015608
    Abstract: A dynamoelectric machine includes a rotor having a rotor shaft; two flux carrying segments rotatably disposed on the rotor shaft; a field coil disposed between the two flux carrying segments, the field coil having a pair of coil leads; an insulative member disposed at one end of the shaft; a pair of slip rings longitudinally spaced on the insulative member and having respective coupling terminals; and a diode having a pair of diode leads, each diode lead electrically connected to one of the pair of coil leads of the field coil and to one of the respective coupling terminals, the diode configured to suppress electrical noise as a result of an interface between the pair of slip rings and respective brushes.
