  • Publication number: 20150252767
    Abstract: A fuel injector is provided that creates variable spray characteristics to effectively reduce emissions, such as NOx emissions and particulate matter. The injector includes a nozzle valve element of the outwardly opening type including a fuel delivery passage and spray holes. The nozzle valve element is operable to move to a low lift position to cause fuel flowing from the spray holes to impinge on the injector body and to deflect toward the combustion chamber, and to move to a high lift position to cause fuel flowing from the spray holes to avoid impingement on injector body and flow in an obstructed manner directly into the combustion chamber. An annular chamber may be formed in the nozzle valve element adjacent the spray holes to receive fuel.

  • Patent number: 9090685
    Abstract: The present invention relates to antibody molecules, in particular antibody molecules that bind Transforming Growth Factor beta (TGF?), and uses thereof. More particularly, the invention relates to antibody molecules that bind and preferably neutralize TGF?1, TGF?2 and TGF?3, so-called “pan-specific” antibody molecules, and uses of such antibody molecules. Preferred embodiments within the present invention are antibody molecules, whether whole antibody (e.g. IgG, such as IgG1 or IgG4) or antibody fragments (e.g. scFv, Fab, dAb).

  • Publication number: 20140360460
    Abstract: The present disclosure provides an improved system and method of operating a fuel injector of an engine to provide at least two different types of fuel spray in a combustion chamber of the engine by application of ultrasonic pulses to fuel in the fuel injector during an injection event. A first type of spray includes larger droplets that reduce the effective diffusion combustion area around the droplets and a second type of spray includes relatively small droplets that increase the effective diffusion combustion area around the droplets.

  • Publication number: 20140361096
    Abstract: The disclosure provides an improved fuel injector and method of operating the fuel injector to provide at least two different types of fuel spray to a combustion chamber of an internal combustion engine. The two types of spray are formed by providing a first fuel pressure to the fuel injector during a first portion of an injection event at a first pressure and providing a second fuel pressure to the fuel injection during a second portion of the injection event, and maintaining a substantially constant fuel flow rate throughout the injection event.

  • Patent number: 8757047
    Abstract: A fluid control device for use in a high pressure fluid system, the device including a device body with a cavity and a high pressure circuit, a plunger positioned for reciprocal movement in the cavity, and a leakage reduction cap mounted to the plunger for reducing fluid leakage flow. In one implementation, the leakage reduction cap includes a flexible portion positioned between the device body and the plunger, and defining an annular clearance gap between the leakage reduction cap and the device body. The flexible portion of the leakage reduction cap resiliently flexes radially outwardly in response to fluid pressure forces to reduce the annular clearance gap so as to minimize fluid leakage flow through the annular clearance gap.

  • Publication number: 20130138752
    Abstract: Systems and methods for managing computer-assisted communications channels based on relationships between users who wish to communicate with one another are described. The relationship-managed communications system allows users to retain control over whom they permit to communicate with them and under what conditions such communications may take place, for example when they take place and/or using which communications channels, by allowing pairs of users to establish relationships which specify communications permissions. Users of the system provide their contact information to the relationship-managed communications system, and the system uses the securely stored information to mediate the establishment of communications channels between users. Embodiments of the system may intelligently route communications to substitute channels based on relationship-related and other information.
