  • Patent number: 4533891
    Abstract: A two pole stationary coil rotary magnet motor which provides for increased work and reduced rotary inertia. The motor consists of two main assemblies, a rotor assembly contained within a rotor casing and a stator and housing assembly surrounding the rotor casing. One end of the casing is closed, whereas the other end is open to eliminate the need for a dynamic shaft seal. Fluid enters the casing at the open end thereof to provide a lubricating fluid for the rotor bearings and a heat conductive path. The rotor casing isolates the critical movement of the rotor from the contaminated atmosphere of the stator environment and allows replacement of the stator assembly without disturbing the rotor assembly. A permanent magnet rotor may be formed using one or more rare earth magnets which may be suitably bonded to the rotor shaft. A protective cover surrounds the rotor magnets to eliminate potential rotor magnet breakage contamination.

  • Patent number: 4529140
    Abstract: Continuous strip accumulator includes a convolution transfer annulus providing for controlled expansion and contraction of the stored convolutions between inner and outer sections within the accumulator. During mill match operation of the accumulator, the convolution transfer annulus is retained against movement but still provides support for the strip material as it moves from the inner section to the outer section. A differential drive between the entry and exit pinch rolls provides for mechanical synchronous operation of the entry and exit pinch rolls during the mill match mode. During the welding mode, when it is desired to replenish the supply of strip material, movement of the incoming strip is stopped and the convolution transfer annulus is driven by the differential drive in a direction causing positive transfer of the convolutions from the outer section to the inner section in mechanical synchronism with the exit pinch rolls to provide a continuous uninterrupted supply of strip material to the mill.

  • Patent number: 4524906
    Abstract: A hot air modulating valve for mixing hot air with cold air flowing in a duct, the modulating valve having a torque motor operated pilot valve to position the modulator valve to maintain a predetermined temperature of the hot air-cold air mixture. The temperature of the mixture is sensed by a thermistor which in conjunction with a tri-mode (proportional plus integral plus derivative) electronic controller which provides an input current signal to the torque motor to position the modulator valve in proportion to the input current signal, produces zero steady state errors, and provides an anticipation effect to compensate for control system time lags. The controller has auxiliary inputs which when exceeding predetermined values switch the air mixture temperature at the thermistor to a lower setting. The modulating valve has a relatively low gain during the initial portion of its opening stroke to improve system dynamic stability and has a position feedback to the torque motor operated pilot valve.
