  • Patent number: 6653587
    Abstract: A method of separating isotopes from polyatomic molecules, in particular 13C from trifluoromethane HCF3, by applying to the polyatomic molecules in the gas phase two infrared laser beams of different frequencies. The first laser has a frequency appropriate to excite a low overtone transition of a light atom stretch vibration and produce vibrationally pre-excited molecules enriched in the desired isotopes, for instance 13C. The second laser has a frequency and energy fluence to selectively induce dissociation of the vibrationally pre-excited molecules by infrared multiphoton excitation.

  • Patent number: 4356724
    Abstract: An apparatus and method is disclosed for testing automatic vehicular transmissions. The transmission tester of the invention includes input adjustment elements and output adjustment elements which permit various makes and models of transmissions to be installed in the tester for testing. The torque converter of the transmission under test is operatively connected to a drive shaft of the transmission tester. The output of the transmission under test is operatively connected to a load device which provides a loading torque to the output shaft. During the test procedure, the torque converter is rotated at varying speeds while a loading torque is imparted to the output shaft. A vacuum is supplied to the vacuum modulator control of the transmission under test, and the hydraulic pressure of the transmission under test is monitored.
