Among other disclosed subject matter, a computer-implemented method for animating an image element includes determining that a trigger element defined by a trigger element occurs. The method includes, in response to the trigger element, applying an animation effect to a group that comprises at least one image element. A first association between the animation effect and the group is configured for another animation effect to selectively be associated with the group, and a second association between the trigger element and the animation effect is configured for another trigger element to selectively be associated with the animation effect.

A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.

A fuel injector for use in a internal combustion engine is disclosed. The fuel injector includes a body having a discharge end and a longitudinal axis extending therethrough, and an electromagnetic coil located within the body. The fuel injector further includes a fuel metering valve operable between an open position and a closed position and an air metering valve operable between an open position and a closed position. The fuel injector also includes a valve seat located within the body proximate to the discharge end and includes an orifice extending therethrough along the longitudinal axis. A needle is reciprocally mounted along the longitudinal axis between an open position and a closed position. The needle has an upstream end, a downstream end, and a needle channel extending therethrough along the longitudinal axis. The needle engages the valve seat in the closed position. A guide is disposed along the longitudinal axis such that the upstream end of the needle is reciprocable within the guide. A seal having a seal opening therethrough is located within the guide. A bellows fluidly connects the seal opening and the needle channel. The bellows and the guide form a generally annular chamber therebetween. The bellows is movable between a compressed and an extended position. The annular chamber is adapted to receive fuel. The seal prevents the fuel in the annular chamber from entering the needle channel. A method of operating the fuel injector is also disclosed.

A flow straightener and a controlled disturbance element are interposed between the injector needle seat and the discharge orifice disk of a fuel injector. The flow straightener straightens flow eliminating turbulence prior to fuel discharge. The controlled disturbance disturbs the fuel flow providing controlled atomization. A spacer is provided between the flow straightener and the controlled disturbance element as well as between the controlled disturbance element and the discharge orifice disk delimiting flow recovery regions. By varying the diameter and/or height of the spacers, in conjunction with the controlled disturbance element, an adjustable level of flow disturbance can be obtained, leading to variable degrees of atomization. In one arrangement, the flow straightener and the controlled disturbance element are combined into a single flow element performing the functions of both the flow straightener and the controlled disturbance element.

Opening and closing times of a fuel injector are accurately determined in accordance with the energy content of an accelerometer trace. The energy content of an accelerometer trace is determined in accordance with a predetermined relation. A line is defined between known points prior to and after the opening or closing time. The normal distance between the line connecting known points and the accelerometer trace energy content is maximum at the inflection point, which corresponds to the opening or closing time. With this data, an ECU can be properly programmed to more accurately control an injector stroke, thereby improving engine performance.

A separate thumb accessible pushbutton operated circuit revises the power operated tube nut wrench at a reduced speed to intercept a home stop wherein after the wrench is automatically shut off on the sensing of current rise in the motor on stall to avoid over stress and unnecessary heat buildup.
摘要:
The atomizer is a cap-shaped shroud that contains a stack of flat stamped metal inserts. When assembled onto the nozzle of a fuel injector, the atomizer causes the inserts to be axially sandwiched between the shroud's end wall and the exterior end of the nozzle. In the zone of sandwiching, the inserts have circumferential discontinuities that in cooperation with the nozzle end and the shroud's end wall define air assist openings for the assist air to flow radially inwardly toward the injected fuel that has just been injected from the nozzle. An air assist opening in one insert is thereby both circumferentially and axially offset from an air assist opening in another insert.

A cover retainer assembly for a support member having a cavity and an air bag disposed within the cavity includes a cover member closing the cavity and having at least first and second edges, a structure for fixedly securing the first edge of the cover member to the support member and a structure for releasably retaining the second edge of the cover member to the support member to allow the cover member to swing open toward the first edge upon deployment of the air bag.
