摘要： A control lever assembly with handle lockout capability including a lever element selectively positionable in a locking position and lockable therein by movement of a handle thereof to a lock position. A first biasing member is disposed on the lever element in an operative position to exert a first biasing force against a detent element, and a second biasing member is disposed in opposition to the first biasing member and is operable to hold the detent element to allow free pivotal movement of the lever element relative to a base.

摘要： A system and technique for dynamically and historically evaluating useful life of coiled tubing. Methods are detailed wherein a monitor and system are equipped for enhanced evaluating of coiled tubing fatigue life based in part on the orientation of the coiled tubing during use. This may be obtained through the tracking of a seamweld of the coiled tubing. Additionally, reliability of the coiled tubing over various uses may be determined on an ongoing basis as a result of acoustically acquired data during operations. In either case, the monitor may be of a magnetic flux data detection variety.

摘要： A poppet valve arrangement is provided and has a poppet slideably disposed therein. The poppet has an odd number of integral guide legs formed thereon about the periphery of the poppet. The odd number of integral guide legs are evenly spaced from one another and are of a size sufficient to permit fluid to freely flow thereby when unseated. The integral guide legs also function to permit the poppet to freely slide, without binding, within a bore of the poppet valve arrangement. The poppet having integral guide legs is compact, versatile, cost effective to produce and has good strength.

摘要： A single lever control assembly that limits motion due to the inherent design of the assembly. In other words, no additional components are required to limit the motion of the single lever control assembly. The assembly includes two U-shaped members each having a base and parallel legs extending from the base, a lever connected to one of the U-shaped members and a pivot block interconnecting the parallel legs for allowing the U-shaped members to rotate relative to one another. The assembly has at least one of the parallel legs having a projection that engages one of the parallel legs of the other U-shaped member. In general, the single lever control assembly is a type of modified universal joint whose movement is limited by a projection.

摘要： Hydrostatic transmissions are useful for propelling a machine to do work and travel relative to the ground. In performing work functions and during travel it is desirable to adjust machine speed to aid in handling the machine. The subject hydrostatic transmission control system includes a infinitely adjustable creeper hand lever which can be moved to any desired position and be maintained in the selected position until moved by the operator. A spring biased inching pedal can be used in combination with the creeper lever to further adjust the machine speed. This arrangement of components provides a control system for the hydrostatic transmission which can be adjusted and maintained at a desired setting.

摘要： There is provided a countermeasure defense system against hostile missiles by employing non-explosive intercepting (“NEI”) elements 14 deployed by the spin stabilized rocket 10. The NEI are carried in a payload section 17 and contained by a sleeve assembly 16 which is removed by a drive mechanism 20 or a pyrotechnic device 152 after a countdown time delay programmed into the trigger release assembly 46 as controlled by the control unit 150. The drive assembly includes a drive rod 26 that is releasably held by a release assembly 46 a compressed coiled spring unit 30 drives the sleeve assembly 16 forward exposing the payload section 17 to the centrifugal force of the spin stabilized rocket propelling the NEI elements out from the rocket at constant angular velocity creating an interceptor cloud of elements. In another embodiment the pyrotechnic device 152 detaches the shearable screws 170 that secure the payload section 117 from the rocket engine housing 102 thereby setting the sleeve 121 free from the rocket housing 102.
