Abstract: A method of predicting fatigue failure in a filled polymeric material is provided. The method involves the calculation of stress at the region of highest stress using an equation which includes as parameters, regression coefficients of the stress vs. modulus obtained from a finite element analysis. Once the regression coefficients are obtained, there is no further need to perform a finite element analysis. The calculated stresses are numerically integrated in a damage equation using a Monte Carlo method, using a cumulative model to estimate when failure will occur. The method has been tested in the case of temperature stress loading of a solid propellant rocket motor.

Abstract: A push button actuator including a plunger movable between return and actuating positions, a conduit with an axial bore therethrough and a core slideably disposed within the bore. The first end of the conduit is operatively connected to the plunger and moves substantially with the plunger. The second end of the conduit and the first end of the core are fixed with respect to the movement of the plunger between its return and activating positions. Movement of the plunger from its return position to its actuating position pushes the first end of the conduit away from the first end of the core, causing the second end of the core to be drawn towards the second end of the conduit. The movement of the second end of the core may be used to activate a reaction mechanism operatively connected to the second end of the core.

Abstract: A positioning device for a power tool. A tool, such as a drywall screw gun, is equipped with a projector which projects two light rays, which form a “V.” The axis of a screw driven by the gun lies in the plane of the “V,” as by bisecting the “V.” If the two rays are positioned so that they illuminate a framing member, such as a 2×4 stud, then this axis will intersect that stud. In effect, (1) the stud becomes the horizontal base of a triangle, (2) the legs of the “V” become the sides, and (3) the axis becomes the altitude. The altitude (axis) necessarily intersects the base (stud). This intersection occurs whether or not a sheet of material, such as drywall, covers part of the stud, provided extremeties of the stud are exposed for the illumination described above. Thus, the location of the concealed part of the stud can be determined, despite the fact that a sheet of material obscures that part.

In order to permit secure attachment of the pressure medium lines even when the minimum thickness which is necessary for the use of the standardized connection thread is not present, the outside of the casing of the cylinder is flattened in the vicinity of the exit point of a duct provided for the supply of pressure medium. A connection plate which is provided with ducts for the pressure medium is secured to the flattened part of the casing, and the connection plate is provided with a port for a pressure medium line.

When the treated food passes through said cutters, the treated food is cut a thrust with a depth and a width and then cut off by the cutters such that finished products with a desired width can fall down through an output slot on the bottom plate.

Abstract: The dog clutch for a square baler is normally retained in a disengaged position as a continuously driven sprocket rotates around it during baling operations. When a retainer for the dog is released, the dog is released by the retainer and flips out to an engaged position so as to be driven through one knotter revolution by a driving lug on the rotating sprocket, whereupon it is reset by the retainer into its disengaged position. An external lobe on the rotating sprocket blocks releasing movement of the retainer if the driving lug of the sprocket is in the immediate vicinity of the dog, which could otherwise cause an insecure engagement of the lug with the dog. The dog-engaging seat on the retainer is spring-loaded to provide yieldable relief in the event binding starts to occur between the retainer and the dog.
