Abstract: A trigger assembly and associated method for use for the adjustment of trigger pull force of a firearm. The trigger assembly having a housing with an adjustment means in the form of a fastener in communication with one or more trigger springs that interface with a trigger. The adjustment means can be configured to adjust a length of one or more trigger springs to adjust the trigger pull force of the trigger assembly. A calibrated force tester can be coupled to a portion of the trigger to test the amount of trigger pull force necessary to release a hammer of the trigger assembly. The trigger assembly enables a calibrated repeatable method of giving a user the ability to adjust the trigger system pull force by the means of a calibrated laser etched scale on the trigger housing that works in conjunction with the adjustment means.

Abstract: A cabin assembly may comprises a door assembly comprising an outer surface, an inner surface, and a seal. The cabin assembly may further comprise a cabin frame comprising hinge assemblies pivotably coupling the door assembly to the cabin frame and a seal surface defining an opening into the cabin frame. The seal surface may contact and compress the seal of the door when the door assembly is in a closed position. The seal surface may include an angled seal surface that is provided at an angle with respect to the inner surface of the door assembly. The angled seal surface may be located proximate to the hinge assemblies. The angled seal surface may prevent a portion, of the seal of the door, from being compressed above a threshold when the door assembly is in the closed position.

Abstract: A cab enclosure for a machine includes a cab enclosure framework formed of a plurality of frame members. The cab enclosure framework defines a plurality of cab enclosure sides. The cab enclosure further includes a plurality of brackets secured to at least two frame members of a first cab enclosure side. The cab enclosure further includes a mounting frame having a substantially planar shelf portion and an attachment portion. The attachment portion is secured to the plurality of brackets and extends around the shelf portion. The cab enclosure further includes a panel including a peripheral portion secured to the shelf portion of the mounting frame.

Abstract: An adjustable striker bolt assembly includes a mount having a first slot oriented along a first axis and a second slot oriented along a second axis. The second axis is disposed at a predetermined angle to the first axis. The adjustable striker bolt assembly further includes a striker bolt supported in the second slot of the mount.

Abstract: Methods and systems, including computer program products, for monitoring and analyzing a database performance problem stored in a separate performance database with cube-based analysis program tools. The methods and systems include means for detecting one or more performance problems, mapping performance problems to cubes, filling the cubes with performance data collected before, and outputting the filled cubes to an output interface usable to deploy said cubes for cube-based database performance analysis.

Abstract: An improved Wankel-type rotary engine having a one piece manufactured side sealing system to improve engine oil leakage and combustion chamber lubrication leakage over the entire seal. The rotor of the Wankel-type rotary engine acts like an internal supercharger thereby improving the power output of the engine. An electronic circuit operates to open the peripheral port at a desired RPM to a desired position. The rotor housing for the Wankel-type rotary engine is ground using a horizontal machining center with a custom parameter driven program and is finished in a spiral overlapping process. The seals for the Wankel-type rotary engine are designed and programmed into a Wire Electrical Discharge Machine wherein perfect consistent apex seals are manufactured out of a single block of material.

Abstract: A computer controlled pull gun system for pulling interference fit fasteners into a mounting hole. The pull gun has a rotatable and axially movable mandrel the is driven by a pneumatic motor. An axially movable piston in a hydraulic cylinder of the pull gun is attached to the mandrel to move it axially after it has been threaded into an interference fit fastener. A digital control system precisely controls the operation to the functions thread mandrel, pull mandrel, unthread mandrel to quickly and efficiently install a fastener. The digital control system controls pressurized fluid pneumatic and hydraulic valves to perform the installation functions. The digital controller responds to commands from buttons on the pull gun that select the functions and determines when a fastener has been properly installed by feedback from a pressure sensing transducer. A reset command button is provided on the pull gun to abort an installation or reset the pull gun for a new installation.

Abstract: A lock nut to be threaded onto a threaded shank which has a keyway. The lock nut has a base, a key on the base to fit in the keyway, a peripheral wall with axial angularity spaced apart recesses, and a wave spring. The wave spring has ridges and radial tabs to fit in the recesses. An internally threaded nut has radially-extending grooves complementary to the ridges to hold the nut against rotation relative to the wave spring when the ridges fit in the grooves. The tabs can be contacted by a drive member to compress the wave spring and remove the ridges from the grooves to enable the nut to turn during installation and removal.
