  • Patent number: 4450753
    Abstract: An electro-hydraulic proportional actuator in which the actuator piston position is hydraulically controlled by fluid flow through solenoid valves operable by an electronic control system. An operator control provides an input voltage representing a desired piston position and a transducer generates a voltage representing the actual piston position. The difference between the input and output voltages generates a difference or error signal that is fed into a feedback system including a sample-and-hold circuit. A clock logic system is provided for transmitting the signal from the feedback system to the solenoid valves at predetermined intervals to activate either valve to move the actuator piston in either direction or to activate both valves to hold the piston at a desired position.

  • Patent number: 4422474
    Abstract: An application of the basic system of patent application Ser. No. 149,065 for operating a remote hydraulic valve. An electro-hydraulic actuator is mechanically linked to the control member of the remote valve. An input control signal is generated by multiplying a signal from a control handle position transducer by a scale factor constant produced by a full control setting with a gain control circuit. The gain control circuit also operates to set the constant to unity in case the signal from the handle position transducer exceeds a predetermined level corresponding to a maximum control handle setting.The control handle itself has four positions: Float, Lower, Neutral and Raise. The handle is biased so that if the handle is released from any position other than Neutral, the handle will go to the Neutral position provided a detent is off. The detent is put in the "off" position by an electrical solenoid which is actuated whenever the supply pressure to the remote valve exceeds a set value.

  • Patent number: 4397490
    Abstract: A vehicle bumper that incorporates a "C" section face bar attached to a truss-formed backplate to achieve a box section construction. The face bar, although a conventional "C" section, has more nearly horizontal upper and lower shelves combined with a reduced frontal face height to offer, when further combined with the backplate, a nearly square box beam. Functional height is extended beyond the beam section with a plurality of strategically located underride stops drawn from the lower shelf. These stops provide low pendulum impact performance at minimal weight while facilitating forming of the bumper beam ends. The stops preferably are concealed with a flexible shield which provides conventional appearance in addition to opportunities of cost, weight, airflow and model appearance differentiation when replacing separate air deflectors and sight shields. The bumper assembly configuration provides a highly weight efficient section modulus, improved torsional stiffness and improved dent resistance.
