Abstract: FAULT DETECTION FOR WHEEL SLIP CONTROL SYSTEM     Abstract of the Disclosure A fault detection system containing three modes of system shutdown, temporary, latching or permanent, dis-ables an automotive wheel slip control system upon detecting faults in the speed sensors, control valves or interconnecting cables.  Temporary shutdown is per-formed immediately following turn on and whenever certain supply voltages drop below threshold levels.  Temporary shutdown is automatically terminated at the end of a predetermined time after turn on or when the supply voltages return to normal.  Latching, resettable shutdown is performed in response to excessive apparent speed difference between a pair of wheels where the apparent difference endures too long.  Latching shutdown is also performed in response to excessive actuation time of one or the other of two wheel slip control system solenoid valves and in response to actuation of a second solenoid valve in the absence of cycling of the first solenoid valve.  Reset after latching shutdown is performed by re-moving and reapplying power to the fault detection system.          Permanent shutdown is accomplished when cyclic sensor faults cause spurious operation and when solenoid energi-zation is not terminated by inhibit signals generated during latching shutdown.  Reset after permanent shutdown is accomplished by replacement of an external power supply fuse which is blown by the operation of the permanent shutdown function.  All fault actuations provide energiza-tion signals of an external warning indicator and in-hibition of external circuits.

Abstract: ABSTRACT OF THE DISCLOSURE A self-erecting highway guide post for insertion in the ground is constructed in the form of a resilient plastic channel having a substantially flat center surface flanked on either side by a pair of flat side portions which are joined at an obtuse angle to the center portion by curved surfaces. A second, arcuately cross-sectioned channel is attached by fasteners through the center portions of each channel to the rear of the first channel. The rear, concave surface of the arcuate channel is directed toward the rear surface of the first channel and lies within its side portions. Such a configuration results in a self-erecting highway guide post when one end is imbedded in the ground to denote the margin of a highway. When the post is struck the curved portions flatten allowing the post to bend when run over by a vehicle and to recurve once the vehicle passes to re-erect the post. The self-erecting post may include features including integrally constructed barbs or holes to prevent removal of the channel once inserted in the ground, reflective elements attached to the face of the channel such as reflective tape, construction from a thermo-plastic poly-carbonate resin, and a construction in which the curved portions joining the sides to the central portion are uniformly curved. Other embodiments may omit the second arcuately cross-sectioned channel or may be of the two member con-struction with the first channel being arcuately cross-sectioned.

Abstract: ABSTRACT OF THE DISCLOSURE     An articulated tractor in which there is a front first tractor vehicle and rear second and third tractor vehicles, each of the tractors having an engine for driving the wheels of the tractor and the first tractor having an operator's compartment, the second and third tractors being connected to the first tractor through a cross bar pivotally secured adjacent its longitudinal midpoint to the rear of the first tractor for pivotal movement both about a generally vertical axis and a generally horizontal axis.  The rear second and third tractors are secured to the cross bar by pivotal connections at points equally spaced from the first pivotal means so that the longitudinal axis of the second and third tractors are normally substantially parallel to each other.  The steering is accomplished by a steering control in the operator's compartment which changes the angular relationship about a vertical axis of the cross bar to the first tractor vehicle to cause the longitudinal axes of the second and third tractor vehicles to assume tempor-arily an angular relationship with the longitudinal axis of the first tractor vehicle.  The pivotal connections of the second and third tractor vehicles to the cross bar are designed to permit pivotal movement of these vehicles with respect to the cross bar about their longitudinal axes.          There is also a further cross bar pivotally connected to the second and third tractor vehicles at the rear thereof in such a manner as to allow turning of the tractor vehicles about their longitudinal axes with respect to the second cross bar.  In addition to the two cross bars, there are pull rods extending between the cross bars so as to transmit pulling forces from the front cross bar to the rear cross bar.  The implement to be pulled is coupled to the rear cross bar.  There preferably are three cross bars, one in the center and one extending between the front and rear pivotal connections of the second and third tractors to the two cross bars.  The cross bar is connected to a front tractor by means of a center yoke which is pivoted about a generally vertical axis to the front tractor vehicle and is pivoted about a generally horizontal axis to the cross bar.
