Abstract: An oxygen generator includes a monolithic body having first and second channels extending longitudinally therein. An electrode is operatively disposed in the first channels and a counter-electrode is operatively disposed in the second channels. The second channels are formed in the monolithic body so each second channel is electrically isolated from, yet adjacent to a first channel, resulting in an alternating configuration of first and second channels. The first channels have fluid or oxygen flowing therethrough, while the second channels have the other of oxygen or fluid flowing therethrough. An output manifold, having an oxygen collection area separated from a fluid collection area, operatively engages with the monolithic body. The oxygen collection area receives substantially pure oxygen from one of the second or first channels, and the fluid collection area receives oxygen-depleted fluid from the other of the first or second channels.

Abstract: In many instances it has been a recent trend to incorporate the use of electronic controls into various machine functions to reduce the fatigue of an operator. When incorporated into the steering functions of a machine, the electronic controls often do not provide an operator with an "automotive" feel and thus do not work as well in some machine applications as they do in others. The present invention incorporates a mechanical feedback through the steering controls to provide the operator with a feel similar to that of an automotive environment. In addition, the steering controls operate in a manner which provides a variable ratio of steering wheel rotation to steering control valve actuation depending upon the articulation angle of the machine. In so doing, the function of the steering controls will vary with and enhance the operation of each specific mode of machine operation.

Abstract: In machines that are articulated in response to a steer input mechanism, it is many times necessary for the operator to make a steer input and then to make corrective adjustments in order to obtain the desired steer angle of the machine. In the subject invention, an electro-hydraulic steering system is provided which senses the desired steer input by the operator, senses the degree of articulation of the machine and a microprocessor delivers an electrical control signal (P) to an electro-hydraulic valve mechanism which effectively controls articulation of the machine. Once the machine has reached the degree of articulation desired by the operator, the microprocessor signals the electro-hydraulic valve mechanism to stop articulation of the machine. Consequently, the operator does not have to provide any adjustments thereto. Additionally, the ground speed of the machine is sensed and the rate of articulation is controlled in response thereto.

Abstract: The design and manufacture of past steering and transmission shifting control devices utilized an upright and rockable control handle for the steering function and an actuating element in close association with the control handle for effecting a speed change function of a multi-speed transmission. The design of the control handle does not offer a rotatable steering member which is familiar and easy to operate. The present invention overcomes these problems by providing a steering wheel for steering a vehicle. A means for changing the speed ratio of the transmission is mounted on a front portion of the steering wheel and extends from a front surface so that the changing means may be conveniently accessed by an operator. A means for selecting either the forward or reverse drive condition of the transmission is mounted on the back portion of the steering wheel and extends from the back surface so that the selecting means may be conveniently accessed by the operator.

Abstract: The present invention provides a rollover protection structure that utilizes unitary corner members that are cast pieces that require no additional bracing. In addition, each corner member includes a leg portion that integrally defines an area of reduced cross-section. This reduction in cross-section creates an area of predictable deformation in the structure which will prevent the structure from collapsing on an operator stationed within the cab.

Abstract: Target velocity and range are measured with high resolution in an echo ranging system (sonar or radar) using composite Doppler invariant signals consisting of at least two segments, such as "rooftop" or "vee" HFM signals, such composite signals having ambiguity functions that intersect along the zero-velocity time axis with ridge lines slanted in different directions. A single correlator is used for each segment wherein returns from the target are correlated with replicas of each segment of the composite signal to separately transform the Doppler frequency shifts of the target return into outputs whose time relationship provides a frame of reference for high resolution measurement of the velocity of the target. The time relationship measurement is implemented by a set of tapped delay lines and coherent summers which output a coherent correlation-like detection peak in a bin which corresponds to the target's velocity.

Abstract: False target (reverberation, clutter, etc.) detection is suppressed in an echo ranging system (sonar or radar) in which target velocity and range are measured using a composite Doppler invariant-like signal having at least two segments, such as are present in a "rooftop" or "vee" HFM signal, such composite signal having an ambiguity function with two or more ridge lines of different slopes that intersect along the zero-velocity time axis. A bank of matched filters provides a distribution of outputs which has an ambiguity function-like character with intersecting pairs of ridge lines, the intersecting points of said pairs characterizing the range and velocity of the echo returns. This distribution is adjusted so that the intersecting ridge lines of each pair have equal and opposite slopes with respect to the time axis. In particular, fixed reverberators, which would have ridge lines intersecting on the zero-velocity time axis, would be symmetrical about this axis.

Abstract: A track roller frame assembly for a track-type vehicle includes a rugged and yet lightweight main body including a channel-shaped base, a recoil-mechanism receiving tubular casing overlyingly connected to a first end portion of the base, and a plate structure overlyingly connected to the second end portion of the base. A collar defines a bore therethrough for receiving a support member of a drive wheel preferably containing a hydraulic drive motor, and a support bracket is connected to the tubular casing for pivotally connecting the main body to the main frame of the vehicle. The weight of the superstructure and the tension forces on the drive belt that encircles the track roller frame assembly are advantageously transferred through the collar and the main body along a central vertical plane therealong and to a plurality of roller wheels centrally supported under the base.
