A positive displacement supercharger includes a housing defining a rotor cavity with a pair of positive displacement rotors operative to carry air axially from an inlet end to an outlet in the cavity wall near an outlet end of the cavity. The outlet communicates with an outlet plenum partially defined by the cavity wall. The cavity wall includes a stiff portion defining a plurality of lightening recesses, such as a waffle pattern, limiting distortion of the wall by pulsations in the plenum. The recesses may be time and cost efficiently converted to Helmholtz tuners by covering the recesses with a cover plate, which may be perforated to include at least one tuning opening (perforation) into each tuning chamber (recess) and forming tuning volumes of the tuning chambers and their associated tuning openings effective to attenuate selected frequencies of pulsations in the plenum and thereby reduce undesired noise emanating from the air system of the supercharger.

A system monitors a network or web application provided by one or more distributed applications and provides data for each and every method instance in an efficient low-cost manner. Agents may monitor the performance of the distributed application by the web services and report monitoring data as runtime data to the remote server, for example a controller. The controller may analyze the data to identify one or more performance issues or “hot spot” methods based on current or past performance, functionality, content, or business relevancy. Instructions and/or configuration information may be transmitted by the controller to the agents that correspond to a particular business transaction portion associated with a hot spot. The portions are then monitored to collect data associated with the hot spot and the hot spot data is reported back to the controller.

The invention discloses a titanium alloy laser welding protection method. The titanium alloy laser welding protection method is characterized in that two gas streams are adopted to protect the laser welding process; one gas stream is helium, helium is conveyed to a welding zone through a protection cover arranged at an acute angle to protect a molten pool, and helium flow quantity Q1 is 8 L/min to 16 L/min; the other gas stream is low-ionization energy argon, argon is conveyed to the tail of the molten pool and weld joints through a horizontally placed protection cover to cool metals, and argon flow quantity Q2 is 12 L/min to 20 L/min; and the two gas streams are mutually independent, and argon flow quantity Q2 is greater than helium flow quantity Q1. According to the titanium alloy laser welding protection method, the two different gas streams are adopted, so that effective gas protection can be provided for laser welding of titanium alloy parts, high-quality titanium alloy welded joints can be obtained, and laser welding of a titanium alloy plate with the thickness of 1 mm to 12 mm can be effectively protected.

A precession modulated variable differential transmission having a transfer assembly interposed between a rotational input and output. The continuously variable differential transmission utilizes dampers to induce and control the gyrational and rotational motion of a precessing plate. A core group of elements of the transfer assembly include an axial array of dampers peripherally arranged to engage a swash plate in a torsionally rigid manner. Torque is transmitted via the swash plate to an abutment plate within the transfer case. This differential arrangement produced by interposing the damper array between the input and output results in a swash plate that exhibits the motion of a gyroscope. Its rotational speed is dictated by the prime mover while the gyration component, rotating in the same direction, is modulated by the dampers. As the gyration component alone, is translated to the transfer case, and hence the output, the relationship between the rotating moment and the gyrating moment determines the reduction ratio, and is regulated by controlling the damping rate of the damper array.
