  • Patent number: 9025342
    Abstract: A wedge lock clamping assembly, system and method wherein the module to be clamped in a slot in a chassis has a pair of wedge surfaces oppositely inclined to spaced-apart side surfaces of the slot. The clamping assembly comprises a pair of wedge elements on opposite sides of a movement axis and each wedge element is configured to be disposed within the slot between a respective wedge surface of the module and a respective side surface of the slot. An actuator operates to forcibly urge the wedge elements along the movement axis for causing the wedge elements to be wedged between the respective wedge surfaces of the module and respective side surfaces of the slot for clamping the module in the slot.

  • Publication number: 20120152501
    Abstract: Provided is a heat exchanger having a swirl chamber, an impact chamber and a swirl nozzle connecting the swirl chamber to the impact chamber for directing a swirl spray exiting the swirl nozzle against an impact surface of the impact chamber for outward expansion along the impact surface. The swirl spray impacting the impact surface is a high velocity spray that produces a turbulent flow across the impact surface allowing for increased heat transfer between the impact surface and a heat transfer surface.

  • Patent number: 7901191
    Abstract: An enclosure (100) comprising a wall structure (110) defining a container space (112) and electronic devices (114) contained within this space (112). The wall structure (110) includes an entrance for providing an operative fluid (e.g., a heat-transfer fluid) into the container space (112) and an exit for draining the operative fluid therefrom. The wall structure (110) includes an inducement chamber that, when a motive fluid is introduced through an inlet (120), produces a differential pressure that induces the operative fluid in the container space (112) to flow through the exit to an outlet (122). The wall structure (110) can be at least partially constructed from a stack (400) of plates having openings and grooves forming the inlet, the outlet, the entrance, the exit, the fluid circuits, and the chambers.

  • Patent number: 7484530
    Abstract: A fluid coupling for providing a fluid connection between an electronic module and a rack having an electrical connector to which the electronic module is connected, comprises a male coupler and a mating female coupler. The male coupler includes a male coupler body and a nipple, and the female coupler includes a female coupler body and a socket for receiving the nipple to establish a sealed fluid flow path between the male and female couplers when the couplers are connected together.

  • Patent number: 7083122
    Abstract: An atomizing injector includes a metering set having a swirl chamber, a spray orifice and one or more feed slots etched in a thin plate. The swirl chamber is etched in a first side of the plate and the spray orifice is etched through a second side to the center of the swirl chamber. Fuel feed slots extend non-radially to the swirl chamber. The injector also includes integral swirler structure. The swirler structure includes a cylindrical air swirler passage, also shaped by etching, through at least one other thin plate. The cylindrical air swirler passage is located in co-axial relation to the spray orifice of the plate of the fuel metering set such that fuel directed through the spray orifice passes through the air swirler passage and swirling air is imparted to the fuel such that the fuel has a swirling component of motion. At least one air feed slot is provided in fluid communication with the air swirler passage and extends in non-radial relation thereto.

  • Patent number: 6920749
    Abstract: A multi-function spray nozzle for engine applications useful as a cooling device to introduce a fluid into the fluid stream of the engine, and as a cleaning device to introduce a fluid to clean internal components of the engine. The nozzle includes a multi-layered arrangement of etched plates defining flow paths for the first and second fluids. Non-radial feed slots direct the first fluid into a cylindrical swirl chamber. The swirling fluid exits the swirl chamber through a spray orifice or a prefilmer, depending on whether the nozzle is configured as a simplex or prefilmer nozzle. Other non-radial feed slots direct the second fluid inward, downstream of the first fluid, to create a fine dispersion of droplets for fluid stream cooling purposes. During cleaning, only the first fluid is introduced through the nozzle, which results in a larger droplet size suitable for cleaning purposes of the internal components of the engine.

  • Patent number: 6763663
    Abstract: An injector includes a plurality of flat, circular plates which provide fuel delivery and cooling of the injector. Fuel delivery passages in the plates have swirl chambers and spray orifices which are formed by chemical etching. A pair of fuel delivery plates define a fuel cavity therebetween, and include a plurality of radially-outwardly extending spokes, with the spokes from one fuel plate in adjacent, surface-to-surface relation with opposing spokes from the adjacent fuel plate. A fuel passage is defined between each of the opposing spokes, leading from the fuel cavity to a fuel outlet opening at the distal end of each spoke. A fuel tube delivers fuel to the fuel cavity between the plates, from where the fuel is then directed through the outlet openings. Downstream plates shape the fuel into appropriate sprays for ignition. An upstream cooling plate assembly directs air against the upstream fuel plate, and radially outwardly along the spokes of the upstream plate.

  • Patent number: 6173862
    Abstract: A multi-flavor post-mix dispense head includes a nozzle having a plurality of concentrate inlet ports for directing concentrate(s) to a plurality of outlet ports; and a diluent inlet port for directing a diluent to an annular outlet port, surrounding the concentrate outlet ports. The annular diluent outlet port has a configuration which forms a cylindrical outlet flow of diluent surrounding a liquid stream of concentrate from any of the concentrate outlet ports. The cylindrical outlet flow of diluent combines under surface tension into a single stream to form a freely-supported cup downstream from the nozzle. The concentrates are respectively introduced through the concentrate outlet ports internally of the cup in a stream or spray to be mixed together with the diluent and then flow downstream together in a homogenous mixture.
