  • Patent number: 5403384
    Abstract: In a regenerable collective protection system the turbine of an air cycle machine is driven by a potion of the clean air output of a pressure swing adsorber bed pair in the system. The beds in the pair are used alternately to cleanse contaminated air. They are then alternately purged of contaminant products. Valves are used to direct these alternate operations. The valve closures cause overpressures in the clean air output. The overpressures are predictable in relation to the valve actuation sequence and are removed by coordinating operation of a surge air bleed valve in the clean air output with valve actuation in the pressure swing adsorber bed pair.

  • Patent number: 5373734
    Abstract: A method and apparatus for measuring the quality of a coating on a plate. The invention uses a method of measuring the impedance of a coating on a plate, which uses the steps of placing the coating on a plate in a chamber, and then placing a counter electrode in the chamber so that the coating lies between the plate and the counter electrode. A reference electrode is placed in the chamber so that the coating lies between the reference electrode and the plate, and the chamber is filled with a fluid with an ionic substrate. A potentiostat induces a voltage between the plate and the reference electrode, and the impedance of the coating is measured to determine the quality of the coating.

  • Patent number: 5337885
    Abstract: A travel monitor for a rectangular sludge conveyor having a plurality of scrapers attached to and driven by a pair of chains, each of which is formed in a closed loop having an upper run. A pair of detector sprockets independently engage and are driven by the upper runs. Switches positioned adjacent the sprockets create a series of pulses in response to their rotation. The phase difference between the series of pulses resulting from rotation of the sprockets is detected, and a misalignment alarm is activated when the phase difference exceeds a predetermined amount.

  • Patent number: 5335856
    Abstract: A trailer mounted sprayer having an air boom supported from the trailer frame by a four-bar linkage movable by a hydraulic cylinder to adjust the elevation of the boom and with ground-engaging wheels rotatably attached to bell cranks mounted on the frame and pivotable by cylinders to control the ground clearance. Accumulators isolate the frame from shock loads created as the wheels traverse uneven ground and also isolate the boom from shock loads that would otherwise be transmitted from the frame to the boom. A draft member pinned to both the trailer and to the tractor pulling the trailer has hydraulic jacks to determine which of the pinned connections will control the pivotal movement between the tractor and the trailer.

  • Patent number: 5307279
    Abstract: The invention provides a wheel balancer that is able to determine if its measurements are accurate. The invention takes a set of measurements and determines if the measurements are sufficiently consistent. If they are sufficiently close the invention uses the measurements to calculate wheel imbalance. If the measurements are not sufficiently close the invention uses the measurements to calculate wheel imbalance. If the measurements are not sufficiently close the invention rejects at least one data point and collects more measurements until either the invention yields sufficiently close data points or the machine is stopped. A display is provided for diagnostic messages.

  • Patent number: 5289100
    Abstract: A propulsion system for using a pair of electric induction motors to power a pair of vehicle drive wheels. The motors are driven by pulses of electric current from a common dc bus. The inductance of stator windings cause electric current to power the motors during the time between pulses so power from the dc bus is low. When a vehicle is making a tight turn, an inside motor provides an electric current to the dc bus to supply additional power to an outside motor. Speed and steering signals operate the electric motors and control speed of an engine and an alternator which supply power to the dc bus.
