  • Automatic velocity and position controller for a film processor
    Patent number: 4385821
    Abstract: An automatic controller for a film processor is characterized by a motor energy signal generator which is responsive to both a position error signal and to a velocity error signal. The motor energy signal is periodically applied to a drive motor for the processor to modify the portion of the available energy transmitted from a source to the motor to restore the actual film position to within a predetermined range of an ideal film position and to restore the actual velocity of the film to within a predetermined range of an ideal film velocity.

  • Apparatus for producing electrical energy
    Patent number: 4385246
    Abstract: An electrical generator comprises a stationary permanent magnet for establishing a magnetic field, one or more sensing coils responsive to the magnetic field, and a diamagnetic blocking element movable between the magnet and the sensing coils for periodically interrupting the magnetic field to produce electrical energy in the coils. A preferred embodiment includes a pair of semi-circular coils arranged side-by-side in the magnetic field and a rotatable blocking disc interposed between the magnet and the coils. The disc includes a semi-circular portion of superconductive material rendered impermeable to the magnetic field at temperatures near absolute zero and a semi-circular portion of magnetically inert material to alternately block and pass the magnetic field to the coils upon rotation of the disc.

  • Test in place valve and valve fitting
    Patent number: 4384591
    Abstract: A test in place poppet valve and fitting assembly having a minimal air volume internal configuration is provided for attaching a portable hydraulic test system to a snubber internal hydraulic line. The valve fitting includes structure for connection to the test system. After the valve fitting has been attached to the poppet valve, but before the poppet valve has been opened, a passageway and the interior of the poppet valve are evacuated and filled with hydraulic fluid. A remotely actuated, spring biased probe extends from the fitting through the passageway to engage a poppet for selectively opening the poppet valve. When actuated to an open position, a prong on the probe is inserted into a cavity, and the poppet is supported on the probe. Using the poppet valve and valve fitting, the test system may be attached to a snubber internal hydraulic line 12 without introducing an appreciable amount of air.
