    摘要: An improved fuel cell assembly includes a plurality of series-connected fuel cells each including an electrically conductive separator, a compressed or sintered oxide powder cathode contacting the separator, a solid electrolyte contacting the cathode and a compressed or sintered powder anode contacting the electrolyte. Each of the separator, anode, electrolyte and cathode includes two internal holes each at least partially in registration with each other so that a fuel and an oxygen-containing gas may be admitted to separate tubes in the cell. Preferably, a gasket is disposed in the opening in the cathode receiving the fuel to shield the cathode from the fuel. A second gasket is disposed in the opening in the anode receiving the oxygen-containing gas to shield the anode from oxygen. Oxygen admitted to one of the tubes reaches the anode by first diffusing through the cathode and then being ionically conducted through the electrolyte to the anode. Oxygen at the anode reacts with the fuel, releasing heat. A peripheral barrier may partially protect the anode from oxygen. In an alternative embodiment, each of the elements of the cell includes only one hole, all of which may be aligned to form a single tube for admitting fuel. In that embodiment, oxygen diffuses from outside the cell, through pores in the cathode. In other embodiments, a single central fuel tube may have a plurality of oxygen supply tubes.

    摘要: An electrohydraulic drive for process line equipment, especially a spooler that winds and pays out an indefinite length of metallic strand, varies the output torque of a hydraulic motor by controlling its displacement and the pressure differential between its inlet and outlet. A valve controlled by a proportional actuator reduces the supply pressure of the hydraulic fluid in a feed line for the motor. A sequence valve located in a return line from the motor maintains the pressure at the motor outlet at a preselected and adjustable value. During braking, fluid from the return line is directed to a regeneration circuit that includes a flow divider returning one portion of the flow to the feed line and another portion to a supply reservoir. A servo-amplifier circuit includes an integrating amplifier that compares the actual rotation speed of the motor to a speed command signal. An analog multiplier produces a control signal for the proportional actuator. In the preferred form a tensiometer monitors strand tension and produces an input signal to a computer that modifies the pressure limit signals. The computer also controls the speed command and displacement of the motor. A hydraulic cylinder controls the linear traversing movement of the spooler under the control of a high speed servo valve that in turn is controlled by electronic circuitry. Position, velocity and rotation speed transducers for the spooler and a position transducer for the strand provide input signals to the circuitry.
