    摘要： A process to fracture connecting rods and the like, that are made of high strength materials, comprises of the following mechanisms: (a) Fatigue: fluctuation of stresses in a pre-notched connecting rod due to the use of harmonic excitation will extend the notch tip in the connecting rod and will weaken the predetermined fracture plane by creating micro-cracks, (b) Resonance: resonance occurs when the frequency of the used harmonic excitation matches a natural frequency of the connecting rod, idealized as a structural system, (c) Pre-stressing forces: by applying pre-stressing forces acting in the same loading mode, the stresses in the connecting rod due to several force components can be superimposed, (d) Dynamic force: applying a dynamic force will raise the stress intensity factor, exceeding the fracture toughness of the material.

    摘要： A electronic apparatus manufacturing cell defining an electronic apparatus manufacturing cell envelope having a first side and having a second side opposite the first side. According to one aspect, the electronic apparatus manufacturing cell comprises an infeed conveyor, a pass conveyor and a reject conveyor. The infeed conveyor extends from a point outside of the electronic apparatus manufacturing cell envelope on the first side to a point inside of the envelope.

    摘要： A muffler having a baffle with angled plates includes a one piece baffle, a container and two end caps. The one piece baffle has at least three different configurations. The baffle preferably has two, three or four plates, namely “V”, “Z” or “W” shapes. Each one piece baffle configuration includes openings to allow exhaust flow therethrough. Each one piece baffle configuration is retained in the container. The container is terminated with end caps on each end thereof. At least one inlet tube and at least one outlet tube are attached to a perimeter of the container. In a second embodiment, the container and baffle are formed from a single piece of material. In a third and fourth embodiment, the inlet and outlet tubes are inserted through plates of the baffle. In a fifth embodiment, balanced tubes and chambers are added. In a sixth embodiment, a corrugated baffle is used.

    摘要： According to the invention, parting of the cap of the connecting rod is achieved by engaging the eye of the big end of the connecting rod with two semicylindrical fixtures, respectively a fixed fixture and a movable fixture, which are actuated by a hydraulic actuator which is interposed between them and is adapted to expand the fixtures in a diametrical direction against the inner surface of the eye of the big end of the connecting rod, subjecting the piston of the actuator to the action of a hydraulic fluid fed into the respective actuation cylinder at an optional pre-loading pressure that is in any case lower than the pressure required to reach the yield point of the material of the connecting rod, and producing an instantaneous peak in the pressure of the fluid fed to the hydraulic actuator by means of an auxiliary piston that is subjected to the momentary action of a striking mass.
