Abstract: Abstract of the Disclosure POLYURETHANE BONDED TO CURED RUBBER       CONTAINING A DIENE POLYOL      A method of preparing a composite of polyurethane bonded to the surface of a cured rubber substrate and the resulting composite.  The method requires the rubber substrate to contain an hydroxyl terminated polybutadiene polyol.  The method is practiced by first applying to a cleaned, cured rubber surface containing the polybutadiene polyol a coating of cyanuric acid followed by an additional coating of a phenol formaldehyde resin and then applying a liquid polyurethane reaction mixture which is cured to form the resultant composite.  The invention is particularly directed to the preparation of a tire comprised of a polyurethane carcass applied to a cured rubber tread and to a tire comprised of a polyurethane tread applied to a cured rubber carcass.

Abstract: ABSTRACT OF THE DISCLOSURE    Two separate microstrip antennas are interleaved in the same plane thereby occupying substantially the same area as a single antenna.  Each antenna aperture produces two beams and the configuration for each antenna includes a single feed on each planar array which results in lowered overwater bias error.  Each planar array antenna can have radiating arrays of different radiator spacing.  Using forward firing arrays for one antenna and backward firing arrays for the other antenna, a radiated spacing is chosen for each interleaved antenna which results in temperature compensation in the along track direction.

Abstract: DOUBLE WINDROWING ATTACHMENT FOR HARVESTER                   Abstract of the Disclosure A double windrowing attachment for a harvester comprises a reversibly driveable conveyor shiftable between a first crop discharge position for forming a windrow inboard of one side of the harvester and a second crop discharge position for forming a second windrow along the opposite side of the harvester.  The conveyor is supported on the attachment frame at only three points.  One side of the conveyor is supported on a pair of feet movably supported on an elongated guide.  The opposite side of the conveyor is supported by a shift arm which is used to shift the conveyor.  The shift arm is pivotally mounted at one end to the attachment frame and movably mounted at the other end in a track fixed to the conveyor.  The crop discharge positions are adjustable and permit a double windrow to be formed either in a side-by-side or in a stacked disposition.  To prevent crop from being discharged from the conveyor onto uncut crop, a switch reverses a hydraulic drive for the conveyor responsive to the beginning of movement of the conveyor from the first to the second crop discharge position and reverses the hydraulic drive responsive to the completion of movement of the conveyor from the second to the first crop discharge position.  The attachment is mounted on the harvester frame by moving the harvester from a lowered harvesting position to an elevated transport position.          The attachment is supported entirely off the ground by and extends rearwardly from the harvester frame and counterbalances the weight of the harvester header supported on and extending forwardly from the harvester frame.

Abstract: APPLICATION OF RICHARD N. FARGO THREE-WAY SOLENOID VALVE        ABSTRACT A three-way solenoid valve uses a movable armature housed in a coaxial sleeve and having longitudinal fluid channels on its outer surface and a fluid sealing element on both ends. A first fluid sealing element on a first end of the armature is a resilient ring arranged to cooperate with an adjacent fluid orifice in a valve body to peripherally seal the fluid orifice in response to spring pressure exerted by a spring acting on the first end of the armature in a first position of the armature during an deenergized state of the valve. The armature is provided with a coaxial longitudinal bore aligned with the center hole in the fluid sealing ring. During the deenergized state of the valve, a fluid path is provided between a first fluid port and second fluid port in the valve body via the hole in the sealing ring, the bore in the armature and the channels on the armature.  During an energized state of the valve, the armature is repositioned to a second position to effect a seal between the fluid sealing element on the second end of the armature and a fixed plug in the valve to interrupt the fluid path along the channels on the armature.  In this state of the valve, the sealing ring is separated from the adjacent fluid orifice to provide a fluid path between the first fluid port and a third fluid port.  A rolling diaphragm seal is arranged between the armature and the valve body to isolate the second port from the first and third ports.

Abstract: IMPROVED NEUTRAL START CIRCUIT FOR A VEHICLE INCLUDING A POWER TAKE-OFF ASSEMBLY                  Abstract of the Disclosure A tractor includes a PTO clutch and is provided with a safety interlock circuit including an ignition switch having separate  output  terminals  respectively  coupled  to PTO  and transmission switches that must be closed, by disengaging the clutch and shifting the transmission to neutral, before the tractor can be started.   A start relay is coupled for being energized only when the PTO switch is closed and it then acts to complete a current path between the transmission switch and a starter solenoid.  When de-energized, the start relay acts to complete an alternate current path to the solenoid, this path containing a lamp for indicating clutch engagement and which acts to drop the voltage below that required for starting. Mechanical engagement of the PTO clutch is electrically maintained by a PTO coil coupled in parallel with the start relay and with a reset relay,  the  latter operating when energized to complete an alternate current path for maintaining the PTO coil energized, after the clutch is engaged and the PTO switch opens, for so long as an operator remains seated to close a normally open seat switch which functions to control a transistor that controls grounding of the reset relay.
