摘要： A soil stabilizer comprises a self-propelled vehicle, a rotor having soil-working teeth, and a motor for driving the rotor. The motor is reversible to drive the rotor in opposite directions. The rotor includes tooth holders, each having generally oppositely directed tapered sockets. A tooth is received in one of the sockets so as to project in the direction of rotation. The rotor can thus be effectively utilized in either direction of rotation. The sockets are coplanar and intersect so that the zone of intersection forms an interruption in the tapered engagement between the tooth and socket intermediate the ends thereof to compensate for manufacturing variations in the tapered fit.

摘要： The present invention relates to a soil stabilizer machine with a recycler screen. The soil stabilizer machine includes a horizontal rotor having a plurality of teeth along a periphery thereof. In operation, the machine moves along the ground and the rotor rotates to dig soil material. The soil dug by the rotor is comminuted by the rotor within a housing surrounding the rotor. Inside the housing and behind the rotor a screen is positioned to selectively permit particles of soil of less than a predetermined size to be dispensed on the ground behind the rotor and to selectively return particles of soil or rock greater than the predetermined size to the rotor to be further comminuted by the rotor. In a preferred embodiment, the screen is pivotably mounted within the housing between first and second positions. The screen can be secured in the first position to return particles of greater than the predetermined size or in the second storage position in which the particles dug up by the rotor are dispensed upon the ground behind the rotor without being sized.

摘要： A multi-sensing device is provided which includes a first sensor for sensing a temperature of the fluid flowing through the filter element, a second sensor for sensing a pressure generated by the fluid flowing through the filter element; and an indicator for indicating a condition of the filter system, and a microcontroller operatively coupled to the first and second sensors. The microcontroller executes instructions for receiving temperature data from the first sensor and pressure data from the second sensor; if the temperature data does not exceed a first temperature threshold, monitoring subsequent temperature data received from the first sensor until it exceeds the first temperature threshold; and if the temperature data exceeds the first temperature threshold: determining whether the temperature data exceeds a second temperature threshold and whether the pressure data exceeds a pressure threshold; if the temperature data exceeds the second temperature threshold, activating the indicator to indicate that the fluid is in an abnormal condition; and if the pressure data exceeds the pressure threshold, activating the indicator to indicate that the filter element is in a condemned condition.

摘要： A fluid filter for filtering a circulating fluid includes an outer shell having a closed first end and opposite thereto an open second end which is defined by a peripheral edge. The outer shell further includes a surrounding sidewall which defines a hollow interior and a filter cartridge is positioned within the hollow interior. A nutplate is positioned in the open second end and is assembled to the outer shell with the peripheral edge of the outer shell being formed over a portion of the nutplate. A floating annular retainer is positioned adjacent the nutplate and in cooperation with the formed peripheral edge creates an annular receiving channel. An annular gasket is placed in the receiving channel and is sized such that there is a side-to-side compressive fit established between the annular gasket and the retainer and a similar compressive fit is established between the annular gasket and formed peripheral edge.
