  • Patent number: 5705742
    Abstract: A system and method are disclosed for motoring an engine using an external drive motor for the purpose of performing tests on same. The system and method is capable of operating in three separate modes, a horsepower testing mode, a valve train testing mode, and a lap simulation mode. In the lap simulation mode, for example, the operator may select by way of a computer how many laps are to be run, the length of each lap, and the exact RPM to be used during each second or time period of every lap. In such a manner, the operator may simulate actual races so as to determine how a particular engine or components thereof will stand up to anticipated racing conditions. Another aspect of this invention is the use of a laser affixed to the block for the purpose of measuring vertical valve movement during motoring of the engine. The use of such a laser overcomes numerous problems in the prior art caused by vibration, lighting, etc.

  • Patent number: 5348101
    Abstract: A hydraulic rockshaft control circuit which includes a three-way valve that normally operates the rockshaft is connected to the lift cylinder on a trailing implement. A hitch lock valve connected to the rockshaft control valve maintains the rockshaft in a preselected position regardless of changes in pressure at the valve output. The extend side of the lift cylinder is connected to the control valve output so that the tractor hitch control is used to operate the trailing implement cylinder. To overcome the inability of the three-way valve to positively retract the trailing implement cylinder, a reducing/relieving valve is connected to the retract side of the cylinder and is adjusted to provide just enough pressure to retract the cylinder and raise the implement wheels from ground contact when the extend side is connected to return pressure.A position feedback system on the implement is connected to the hitch control unit (HCU) on the tractor.

  • Patent number: 5339906
    Abstract: A feedback mechanism for providing an implement position signal includes a rotary potentiometer mounted on the implement frame adjacent the rockshaft with the axis of the potentiometer shaft extending parallel to the rockshaft. A linkage structure includes a potentiometer arm connected to a rockshaft arm by a link such that the angle the potentiometer arm forms with the link is acute when the implement is in the transport position and obtuse when the implement is in the lowered field-working range. At the lowermost position of the implement, the link and potentiometer arm approach an overcenter position. The linkage structure provides amplified rotation of the potentiometer shaft relative to the rockshaft when the implement is in the field-working range of positions, while rotation of the shaft is reduced relative to rockshaft rotation when the implement is raised above the field-working position. In the preferred embodiment, rotation of the rockshaft 10.degree.

  • Patent number: 5063729
    Abstract: A cotton path blockage detector has an acoustic output directed toward the discharge door floor on the cotton picking unit directly behind and to one side of the stream of cotton coming off a doffer. When the unit is operating properly, the floor area is generally clear of cotton and a first distance signal is provided. When a blockage occurs, the area begins to fill with cotton and debris, causing a decrease in the monitored distance. A threshold distance signal which is less than the distance signal to the floor causes an alarm to be activated to warn the operator of a plug. To prevent false alarms where the blockage may only be temporary, a slew rate limitation is built into the processing circuit.In another aspect of the invention, the signal radiated into the cotton conveying path is reflected by cotton, and a doppler circuit detects the presence of a doppler shift in frequency indicating moving cotton in the path.

  • Patent number: 4635047
    Abstract: An element placed within a cotton conveying duct of a cotton harvester above the air discharge jet is shaped to shed cotton and supports a vacuum opening which communicates with a simple differential pressure switch through a vacuum conduit. The aspiration effect of normal air flow over the opening provides a vacuum in the conduit which maintains the switch open, but if air velocity in the duct drops below a preselected value due to a plug, low fan speed or faulty hose, the vacuum decreases and the switch closes to energize a warning device.

  • Patent number: 4469185
    Abstract: An improved cutter wheel that is particularly useful with tilling apparatus for sod seeding purposes. The cutter wheel is mounted for rotation by a drive structure that includes a drive shaft. The cutter wheel includes a central disk portion with an outer periphery defining a plurality of equally spaced slots, each for receiving a tip-holding insert. A bullet-shaped tungsten carbide tip is soldered or brazed to the tip-holder and the holder is welded to the disk. The disk periphery is shaped to allow cutting clearance for the tip, to protect the tip from breaking off, and to provide rear support for the tip-holder. The angle at which the tip is connected to the holder is chosen so that the brazed or soldered joint is loaded primarily in compression as the wheel cuts through the soil.

  • Patent number: 4322034
    Abstract: A hydraulic rate control system for maintaining a selected application rate at varying ground speeds. The application rate is selected through an operator control which permits the operator to dial in the spray tip size, the width of the spray pattern per tip and the desired spray rate in gallons per acre, and this application rate can be changed on the go. A ground-driven hydraulic oil pump directs its entire flow through a variable orifice, adjusted through manipulation of the operator control, and the oil pressure acts against a balance valve which maintains the pressure of the chemical to be sprayed equal to the oil pressure at the variable orifice. As the ground speed increases or decreases, the oil pressure and thus the chemical pressure increases or decreases accordingly to maintain the selected application rate.

  • Patent number: 4250968
    Abstract: An improved cutter wheel that is useful in conjunction with tilling apparatus for sod seeding purposes. The wheel has a body fashioned from sheet metal. The periphery is characterized by smooth contours which define the teeth and gullets. The wheel is devoid of hooked sections or notches as well as abrupt gullets where stringy material such as Bermuda grass could become caught or hairpin to cause wrapping. Different teeth are offset in opposite directions from the plane of the body to increase the effective cutting width. Additionally, the symmetry of the cutter wheel is such that it can be mounted for rotation in either direction.
