摘要： A recreational vehicle suspension system and air spring assembly wherein the frame beam on the vehicle has a first leaf spring operably mounted thereto and a first axle is mounted on the leaf spring. An air spring assembly is mounted in tandem to the leaf spring on the frame beam and mounts a second axle. The air spring suspension assembly includes in one embodiment a mounting plate which is secured to the frame beam in overlapping relationship with the leaf spring. A trailing arm is pivotably mounted on an axis transverse to the mounting plate on a depending support at a forward portion of the mounting plate. An air spring is mounted between the trailing arm and the mounting plate to cushion the movement of the trailing arm toward the mounting plate and a shock absorber damps the movement of the trailing arm toward and away from the mounting plate. A side flange on the mounting plate extends along the inner side of the beam opposite the leaf spring and a bottom flange on the mounting plate extends along the bottom of the beam. The shock absorber is secured to the side flange. With the air suspension assembly according to the invention, a leaf spring assembly and an air spring assembly can be mounted in tandem with a minimum space in between the wheels due to the overlapping of the two assembly systems. In another embodiment, the system is mounted in overlapping relationship to a leaf spring with the air spring, shock absorber, and the depending support being mounted directly to the frame. This latter embodiment is used on motor homes where the frame is much stronger than on van type vehicles.

摘要： The method of honing gears which comprises placing the first gear of a first series of gears in tight mesh with a gearlike hone in new condition so as to have a predetermined clearance between the crests of the hone teeth anf the bottom of the spaces between gear teeth, and thus establishing an initial position to be occupied by the first gears of successive series of gears, rotating the gear and hone in tight mesh under light pressure contact to finish the side profiles of the teeth of the gear while material is worn away from the sides of the hone teeth while maintaining the hone in a fixed position. Repeating the process with successive gears in the first series while reducing the center distance between the hone and successive gears to maintain tight mesh as material is removed from the sides of the hone teeth until the crests of the hone teeth approach an interference condition in which they would bottom in the spaces between gear teeth. At this time the honing operation on the first series of gear teeth is terminated and the hone is either replaced with a new hone or is reconditioned by removing material from the crests of the teeth. In either case, substantially the same clearance is introduced between the crests of the hone teeth and the bottom of the spaces between gear teeth of the first gear of the second series. Thereafter, the cycle is repeated on the multiplicity of gears constituting the second series until sufficient material is worn away from the sides of the hone teeth to cause approach to the aforesaid interference condition.

摘要： A coupler for a trailer and the like, the coupler having a body and cap hinged together at a front portion and closeable along parting faces with an internal cavity formed by the body and the cap for a ball which is conventionally secured to the towing vehicle. The body forms a major portion of the ball cavity and includes a ball centering upper surface which extends substantially laterally across the upper surface of the cavity forming a self-centering bearing surface for the ball. A load distributing means is uniquely formed on a rear portion of the parting faces of the body and cap to restrain relative vertical movement between the body and cap along the parting faces thereof. The load distributing means includes a horizontal shelf extending from the ball cavity and a complementary recess, with the horizontal shelf preferably being formed on the parting face of the body. The parting faces are desirably vertical adjacent the ball cavity and juxtaposed locking flanges extend upwardly from the vertical faces of the body and cap. Holes in registry with each other extend through the locking flanges so that the cap and body can be padlocked in the closed position.

摘要： An adjustable phase shifter is connected between a radar scanning beam position sensor which provides an output wave form in accord with the azimuth position of a radar beam and the horizontal input of a cathode ray tube display for the radar. Deviations between the phase of the wave form passed to the display tube and the actual azimuth position can thus be corrected to avoid double images on the display screen which results if there exists any out of phase relationships between the output signal passed to the cathode ray tube display and the actual position of the scanning beam.

摘要： A storage rack assembly including a post of sheet metal or the like having at least one supporting wall with a front face and a back face. A plurality of slots are formed in the supporting wall and are spaced from each other along the length of the post. A beam of sheet metal or the like has a web portion with a front face and a pair of load carrying tabs struck from the front face and spaced from each other in a direction transverse to the length of the beam. Each of the load carrying tabs are received in one of the slots in the post such that the beam extends transversely of the post. A projection is struck from the front face of the beam and engages an edge of the supporting face so that the beam is firmly secured against horizontal movement with respect to the post. An anti-lift tab is provided on the beam to project through one of the slots to firmly secure the beam against vertical movement with respect to the post.

摘要： A gyro hunt damping circuit for electrically changing the phase of the excitation current applied to a synchronous motor to slowly settle changes in the lag angle of a synchronous motor and thereby dampen motor hunting, is disclosed. The current drawn by a synchronous motor is continually sensed by a current detector circuit which provides an output signal representative of the motor current. The detector output signal is applied to a comparator circuit which serves to compare average current drawn by the motor over a long time period to instantaneous current demand over short time periods. The frequency of a square wave generator, which controls the frequency of excitation current from the AC power supply of the motor, is temporarily changed in accordance with any difference between the average and instantaneous motor current demand.
