摘要： A pair of circular, furrow-opening disks, supported by separate, angularly oriented axles, rotatable simultaneously as a unit and converging to a leading zone of interengagement within the ground for preventing soil buildup therebetween, have a wedge-shaped, trailing blade, rigidly supported therebetween immediately ahead of materials gravitating into the furrow, and following at a greater depth, for slicing the series of unplowed scallops at the bottom of the furrow, clearing the furrow bottom of loose soil and forming a truly V-shaped, ridgeless, material-receiving apex compressed into a smooth, firm sidewall formation.

摘要： The applicator comprises a relatively thin, streamlined knife blade adapted to be positioned with its longitudinal axis inclined upwardly and rearwardly during use with a leading edge of the applicator slicing through the subsoil and a lowermost and forwardmost point thereof penetrating the subsoil for the progressive entry of a wedge immediately behind the point which firms up and smooths the lowermost portion of the slice being created by the knife. Upwardly and rearwardly inclined, streamlined wings at the bottom of the blade but above the wedge project beyond the rear of the wedge to define a pocket into which anhydrous ammonia or other substances can be deposited. In one embodiment, the wings commence at the point and diverge rearwardly therefrom at a faster rate than the wedge to provide increased surface area for lifting and fracturing the soil as the knife moves therethrough, providing particular relief in root-bound subsoils. In a second embodiment especially suited for soils which are not self-closing, a pair of outwardly projecting closing fins are provided above and generally rearwardly of the wings to cause the rearwardly flowing soil to be directed downwardly and rearwardly into the slit and around and behind the knife, thus promoting closing of the slit and retention of the deposited substance.

摘要： A shank mounting assembly for a soil opening point permits adjustment of the spacing between a pair of mounting bolts of the assembly for permitting attachment of the assembly to farm implement shanks having bolt holes of various spacings. The assembly includes an elongated adapter having a hidden, internal cavity to which access is gained only by an elongated slot on the backside of the adapter. The cavity and slot are so dimensioned that while the bolts may move lengthwise within the slot for positioning adjustment, the enlarged heads of the bolts remain in the cavity and cannot pass through the slot. By having the cavity accessible only from the back of the adapter and by providing the front face of the adapter with a smooth, continuous, soil-engaging surface, the heads of the bolts are protectively unexposed to abrasive contact with the soil during use.

摘要： A double disc, debris-clearing assembly has a suspension member for releasable attachment to a farm implement and on which is rigidly secured an upright standard. A guide rigid to and depending from the suspension member beneath the standard has a tiltable channel element releasably mounted thereon and provided with an upwardly-extending strap for varying its height along the guide. An adjustable connection is utilized between the strap and the standard. A pair of interconnected brackets carried by the channel element are provided with disc mounts which may, in turn, be adjusted to vary the positions of the discs relative to each other and to their brackets. Accordingly, the suspension member, the standard, the guide, the strap and the channel element are common to the bracket unit and, therefore, the discs.

摘要： A double disc attachment for planters, operating to present a debris-cleared area ahead of the furrow opener of the planter, has one of the discs peripherally fluted so that the discs cooperate in their debris-clearing function rather than work in opposition to one another. The fluting permits lateral displacement by the other disc of debris which might otherwise be contacted simultaneously by the soil-penetrating cutter disc and left lying across the path of the oncoming furrow opener. The discs are properly oriented insofar as tilt, spacing, convergence, relative overlapping and lead are concerned, with at least certain of such relative positioning and depth being adjustable to accommodate for various conditions.

摘要： A knife for applying substances such as fertilizer in solid, liquid or gaseous form cuts a slice in the subsoil with its leading, rearwardly inclined cutting edge and simultaneously firms up and maintains the lower portions of the sides of the slice in readiness for receiving the substance in a pocket formed by a recess at the lowermost rear of the knife in conjunction with the firmed up portions. The slice taken by the slender knife is of such narrowness and the movement of the knife through the subsoil is of such a streamlined nature that the cohesive integrity and inherent resiliency of the subsoil is not destroyed, promoting self-closure of the slice behind the knife, thus greatly reducing the escape of the substance where it is a gas. A forwardly tapering wedge having downwardly converging faces on the bottom of the knife leads rearwardly from a lowermost, forwardly projecting, sharp point to prepare the lower portions of the slice sides in the proper manner, and laterally projecting, forwardly converging wings overlying the recess of the knife behind the wedge help seal the pocket to trap the substance when it is a gas, such wings also serving to return and press subsoil into the slide after the deposit of the substance.

摘要： A novel inflation/deflation system for the pneumatic tires of a vehicle, and particularly of an aircraft, is described, which comprises a housing on the vehicle, such as in the form of a fixed axle housing, on which the tire and wheel are mounted for rotation, and defining a cavity coaxial with the axis of rotation of the wheel for housing the valve and related components; a manifold within the housing defines a manifold chamber containing and supporting an axially movable poppet valve; a remotely controllable solenoid is mounted within the axle housing coaxially with the manifold and poppet valve, the plunger of the solenoid being operatively connected to the poppet valve for axial movement of the poppet valve between open and closed positions in response to operation of the solenoid, whereby pressurized air may be selectively supplied from a pneumatic source to the manifold and to the tire through pneumatic lines connected thereto.

摘要： A valve system for remotely controlling the inflation pressure within a pneumatic tire of a wheel mounted for rotation on an axle of a vehicle includes several improvements. One improvement is a spool valve assembly disposed in a housing mounted within the axle. The spool valve assembly is carried by and rotates with an air manifold formed on the interior of the wheel hub cap. Another improvement is an electrical pressure transducer for monitoring the pressure in the air manifold which is mounted to the manifold and rotates therewith. A pair of electrical inductive coupling rings attached respectively to the housing and spool valve body electrically couple a stationary leading portion of an electrical signal transmitting cable to a trailing portion thereof which is attached to the transducer and moves therewith. A further improvement is a sealing assembly disposed between the housing and spool valve body adjacent the inductive coupling rings. The sealing assembly includes a flexible ring and an expanded flexible band which seats in a curled inner edge of the ring for establishing an air-tight seal between the curled edge of the ring and the valve body when the inflation/deflation function is in operation.
