Abstract: ABSTRACT           This invention relates to a transport wheel assembly for a tillage type agricultural  implement having at least two pairs of ground support wheels mounted on the frame section of the implement.  Each wheel of the pair is journaled in a separate axle mounted on the end of a pivot arm with the pivot arms being mounted in spaced shafts journaled on the implement frame.  The shafts are separated longitudinally of the implement frame or across the width of the same to space the wheels longitudinally apart, and they are also separated in a fore and aft direction of the implement frame.  The shafts of each pair are tied together through a hydraulic actuator which acts as a linkage to transmit motion from one wheel to the other when the implement traverses uneven terrain.          The actuator in one position pivots the wheels in close proximity in the fore and aft direction for stability in turns and raising the implement and hence the ground working tools above ground level for transport.  In the opposite position of the actuator, the implement frame is lowered for working and the wheels are separated in the fore and aft direction to a wide extent for greater stability in traversing uneven terrain.  In the transport position, a strap ties the actuator to a fixed position for safety purposes.  Stops on the frame limit movement of the transport wheels for stability purposes.  On wing sections of the implement, the transport wheel assembly includes an adjustment of the wheel position for depth adjustment of the tools.

Abstract: CLOSED LOOP FUEL CONTROL SYSTEM FOR AN INTERNAL     COMBUSTION ENGINE HAVING AIR/FUEL RATIO ENRICHMENT DURING PERIOD OF ENGINE WARMUP     Abstract of the Disclosure:         A closed loop fuel control system is described for a vehicle internal combustion engine which includes an exhaust gas sensor providing a signal having a value determined by the oxidizing/reducing conditions of the exhaust gases.          An integral controller is responsive to the output of the exhaust gas sensor and provides a control signal varying in a first direction for sensed oxidizing/reducing conditions greater than a desired condition and varying in an opposite direction for sensed oxidizing/reducing conditions less than the desired condition.  A control circuit is responsive to the output of the integral controller to adjust the vehicle engine air/fuel supply device to vary the value of the air/ fuel ratio of the mixture supplied to the engine in a direc-tion tending to maintain the desired exhaust gas condition.          The output of the integral controller is limited to predeter-mined values so as to limit the air/fuel ratio control authority of the closed loop circuit.  A circuit is described which varies the limit of the value of the output of the integral controller in a mixture leaning direction as a function of engine operating parameters related to cold engine operation so as to prevent severe excursions of the air/fuel ratio in the lean direction resulting from certain vehicle operator initiated inputs to the fuel supply device during cold engine operation.

Abstract: REGULATING TRANSFORMER WITH MAGNETIC SHUNT     Abstract of the Disclosure:            A regulating power transformer has a DC-shunt control arranged so that coupling between the primary and secondary windings of the transformer over substantially the entire range from 5% to 95% of rated line input may be achieved, with low harmonic component and low voltage distortion in the output.          A DC-shunt, having a cross-section at least equal to any single path AC magnetic flux core leg is interposed between primary and secondary windings placed on the core legs, with an air gap between each end of the shunt member where it is contiguous to a core leg, and a DC control winding is arranged through at least one window formed in the shunt member.  The AC reluctance through the shunt member and the air gaps at each end is less than the AC reluctance in the principal magnetic path between the primary and secondary windings, so that when there is zero DC current in the DC control winding, there is substantially no coupling between the primary and secondary windings, with substantially all of the magnetic flux established by the primary winding being shunted through the shunt member.

Abstract: A B S T R A C T     A combination pressure reducer and flow control valve which include a valve body and cover means having an upstream port and a downstream port, and two parallel fluid flow passages inter-connecting said ports. An adjustable differential pressure valve means is operatively mounted in a first one of said two parallel fluid flow passages for reducing the upstream pressure of fluid entering the upstream port to provide a reduced downstream pressure at the down-stream pressure port.  A check valve means is operatively mounted in the second one of said two parallel fluid flow passages and it is operative to check the flow of fluid through said second one of said two parallel fluid flow passages when fluid is flowing through said first one of said two parallel fluid flow passages, and to allow flow of fluid through said second one of said two parallel fluid flow passages when fluid is exhausted into said downstream port and out the upstream pres-sure port.  An adjustable fluid flow control valve means is operatively mounted in either one of said two parallel fluid flow passages to pro-vide either a meter in or a meter out action to the flow of fluid through the passage in which the adjustable fluid flow control valve means is mounted.  The function of the check valve means and the adjustable fluid flow control valve means may be incorporated in a single valve means for a meter out action.  An adjustable pre-exhaust valve means may be in-cluded for quickly exhausting downstream pressure simultaneously with the exhaust of fluid flow through the check valve means.

Title: Fuel ignition system control arrangement having a timing circuit with fast reset

Abstract: FUEL IGNITION SYSTEM CONTROL ARRANGEMENT HAVING A TIMING CIRCUIT WITH FAST RESET ABSTRACT An arrangement for a direct ignition type fuel ignition system includes a capacitive timing network which enables a flame relay to operate during a trial for ignition interval, energizing a fuel valve to supply fuel to a burner for ignition, and a flame sensing circuit which causes the flame relay and the fuel valve to be maintained operated only if a flame is sensed before the end of the trial for ignition interval. In the absence of a flame, a diode, back biased by the timing signal, decouples the flame sensing circuit from the timing network. When a flame is established, a further diode, back biased by a control signal provided by the flame sensing circuit, decouples the timing network from the flame sensing circuit. In an embodiment wherein the charging time of a capacitor defines the trial for ignition interval, a fast reset circuit provides rapid discharge of the timing capacitor when power is removed from the timing net-work. In another embodiment, wherein the discharge time of a capacitor defines the trial for ignition interval, a checking relay, energized over normally closed contacts of the flame relay, operates to disconnect the capacitor from a source of charging current and complete a discharge path for the capaci-tor enabling the timing network to generate the timing signal. The checking relay is prevented from operating, thereby main-taining the system locked out, if the flame relay is operated at the start of an ignition cycle.

Abstract: ABSTRACT OF THE DISCLOSURE           A power steering device includes an input member, a sleeve and an output member such that rotation of the input member relative to the output member communicates pressurized fluid through the sleeve to provide a power assist during steering.  At least one pin is disposed between the input member and the sleeve to define fluid paths through the device and limited rotation between the input member and the sleeve increases the fluid flow in one of the fluid paths and decreases the fluid flow in the other of the fluid paths.  A groove in the sleeve and a slot in the input member receive the one pin.  The one pin is normally maintained in spaced relation to the input member by means of an axial cutout in the slot.  In order to control pressure buildup due to fluid flow between the pin and the input member slot, the pin or the input member are provided with axial recesses at the location where the pin is engageable with the input member slot when the input member is rotated relative to the sleeve.
