摘要： A spring biased plunger located on the turbine head cover moves upward into engagement with the wicket gate lever arm when the gates are in a closed position. A pressure fluid operated servomotor is connected to the plunger and is activated to withdraw the plunger out of engagement with the wicket gate lever arm when it is desired to open the wicket gates. An opening in the plunger body aligns with an opening through the lever arm when the gates are in the full open position. A pin extending through both openings locks the gates in the open position.

摘要： A flange clamp having a C-shaped configuration, the opening between the ends of the clamp being slightly smaller than the diameter of the envelope to be clamped. The construction is such that the clamp is snap-engaged on the envelope to provide a security link to the envelope that it is associated with. The clamp is also provided with compression limiters so that only a predetermined compression force will be applied to the envelope flange.

摘要： There is provided in accordance with an embodiment of the invention a wave trap assembly for connection in series with an electrical conductor means such as an electrical power transmission line for the purpose of attenuating or damping transient high frequency phenomena, and comprising a non-magnetic conductor member received in a slot in a stack of magnetic laminations, whereby the inductive effect of the magnetic laminations causes displacement of the high frequency transient currents into a reduced cross-sectional area of the conductor contiguous the outer periphery of the magnetic laminations, to modify the action of the normal high frequency skin effect whereby to more effectively attenuate the high frequency phenomena. The conductor may be cast in the slot. In a modified embodiment, the radially or peripherally outer portion of the conductor lying in the slot of the stack of magnetic laminations may be made of a higher resistance material than the radially inner portion of the conductor whereby to further attenuate high frequency transient currents flowing in the peripherally outer portion of the conductor. In a still further embodiment of a conductor lying in a slot in a stack of magnetic laminations, a radially inner conductor portion of larger cross section may be connected by a narrow cross-section neck portion to a radially outer conductor portion of smaller cross section than the radially inner conductor portion whereby to promote the transfer of high frequency transients to the outer portion. In another embodiment, the wave trap assembly may comprise a plurality of circumferentially spaced conductor members lying in slots in the peripheral surface of a drum-like stack of magnetic laminations. In still another embodiment, a plurality of wave trap assemblies may be supported by stand-off insulators and by conducting spacers in such manner as to be connected in series with each other and in series with the power transmission line.

摘要： An aftercooler in a turbo-charged engine including a removable core having supporting plates at intervals along the length of the core. The periphery of the supporting plates and cooling fins between the plates generally conform to the cross section of the opening of the core supporting housing of the intake manifold. The end walls are sealed to form coolant fluid chambers for fluid flow through fluid passages extending longitudinally through the core while the cooling fins and supporting plates spaced along the length of the intercooler core define cross passages for the flow of the intake air.

摘要： A high speed switch for short-circuiting the electrical output of an alternating current generator or other generator. The shorting switch includes a stationary shorting bar connected to one electrical output line to be shorted. The other output lines to be shorted are respectively connected each to a separate hairpinshaped contact carrier of spring material and having low mass and low bounce characteristics. Each contact carrier is normally engaged by a "contact hold-down means" to hold the respective contact carrier and its associated contact out of conductive engagement with the shorting bar. The contact hold-down means is normally held in its contact hold-down (nonshorting) position by a magnetic detent device. Upon the occurrence of a fault in the electrical output system being protected, a signal is transmitted to the magnetic detent device to reduce the magnetic holding force sufficiently to permit the stored energy of the spring-like contact carriers, aided by an auxiliary spring, to rapidly move the contact hold-down means out of hold-down relation to the spring-like contact carriers, the contact carriers with their respective associated contacts moving into conductive engagement with the shorting bar. Shorting of the output lines instantaneously removes the energy source supplying fault current. In essence, the fault current is "diverted" from the fault to the shorting device. A motor driven relatching device is provided to move the armature which supports the contact holddown means into magnetically latched engagement with the magnetic detent means.

摘要： An impact crusher is disclosed having a rotor carrying a pair of hammer bars, with each hammer partly within an axially extending peripheral slot diametrically opposite each other. A portion of each leading hammer face within the slot and a facing wall of the slot cooperate to define therebetween a generally cylindrical cavity parallel to an axis about which the rotor rotates. A twopiece bushing is fitted in the cylindrical cavity at each end of the rotor, and each of the bushings comprises a pair of bushing halves each having a convex semi-cylindrical outer surface. The bushing halves are arranged within the cylindrical cavity with one convex surface engaging the hammer defined portion of the cavity and the other convex surface engaging the slot wall defined portion of the cavity, and with a diametrical plane along which the bushing is split into halves, being substantially parallel to the adjacent leading hammer face. The halves of each bushing define therebetween an internal conical shaped cavity with an apex end pointed inwardly of the adjacent end of the rotor. A frusto-conical plug is inserted into each bushing with apex ends pointed inwardly of adjacent ends of the rotor. A rod passes through central bores in both plugs, and nuts threaded on both rod ends hold the plugs relative to each other. Retaining walls are provided within the cylindrical cavity to limit movement of the bushings inwardly of their respective adjacent rotor ends. Movement of the frusto-conical plugs toward each other therefore moves each pair of bushing halves apart. As each pair of bushing halves move apart their convex outer semicylindrical surfaces move apart and apply forces which are directed radially of the bushings to both push the hammer radially into its slot and tangentially against the back wall of the slot, to securely lock the hammer in its slot.

摘要： A rotary pump having a plurality of impeller blades and a plurality of circumferentially spaced vanes located about the periphery of said blades. The blades and vanes cause the fluid being acted upon by the pump to be delivered in pressure pulses of relatively high frequency and low magnitude. The spacing between adjacent vanes is nonuniform to prohibit uniform pressure patterns in the process fluid.
