    • An ultra precision net shape forming process is disclosed which can satisfy the requirements of MMW and sub-MMW components and sabots for small caliber armor piercing ammunition. The process is well suited to both moderate and high volume applications, and offers the potential for dramatically reducing piece part fabrication costs. The process involves closely controlled high temperature compression forming of metals with cycle times of the order of one minute or less, precise replication of all die features, and very low residual stresses. The ultra precision net shape forming cycle starts following insertion of the billet/blank into an open die. In the preheat phase the press is closed to preheat position where the billet/blank is enclosed in both halves of the die but no force is applied. Following preheat the part is formed employing displacement and force control to insure a fully formed part. After holding for a preset time at the peak force, the press is then commanded back to the loading position. The process has many of the attributes of conventional compression molding of plastics and is well suited to high volume, automated production of complex precision parts.
    • 公开了一种超精密网形成型工艺,可以满足MMW和次MMW组件的要求,并能满足小口径穿甲弹药的要求。 该工艺非常适合中等和高容量应用,并且具有显着降低零件制造成本的潜力。 该方法包括精密控制的高温压缩成形金属,循环时间为1分钟或更短,精确复制所有模具特征,以及非常低的残余应力。 在将坯料/坯料插入开模中之后开始超精密网状成形循环。 在预热阶段,压机关闭到预热位置,其中坯料/坯料被封闭在模具的两半中,但不施加力。 在预热之后,使用位移和力控制形成部件,以确保完全成形的部件。 在峰值力保持预设时间后,再按下按钮返回装载位置。 该方法具有传统的塑料压缩成型的许多属性,并且非常适合于大量自动化生产复杂的精密零件。

    • A fluid ejection system (20) comprising a cartridge (24), an ejector (32, 300) and, optionally, a fill station (28) for filling the cartridge with a fluid, such as a vaccine. In some embodiments (52), the cartridge includes a transfer passageway (96) for receiving fluid from the fill station. In other embodiments (200, 400), the cartridge includes a vented fluid reservoir (208, 408) offset from an ejection chamber (224, 420). In yet other embodiments (500, 600), the cartridge includes a vented fluid reservoir chamber (512, 636) inline with the ejection chamber (508, 644). In still other embodiments (700, 1000, 1100), the cartridge includes first and second chambers (728, 736, 1036, 1048, 1136, 1148) initially fluidly sealed from on another by a valve, e.g., either a traveling valve (704, 800, 900, 1200, 1300) or a temporarily stationary valve (1004, 1104).
    • 流体喷射系统(20),其包括筒(24),喷射器(32,300)和可选地用于用诸如疫苗的流体填充盒的填充站(28)。 在一些实施例(52)中,盒包括用于从填充站接收流体的传送通道(96)。 在其他实施例(200,400)中,该盒包括从喷射室(224,420)偏移的排出的流体储存器(208,408)。 在其它实施例(500,600)中,该盒包括与喷射室(508,644)成直线的通气的流体储存室(512,636)。 在另外的其它实施例(700,1000,1100)中,盒包括首先和第二腔室(728,736,1036,1048,1136,1148),其通过阀例如流动阀(704) ,800,900,1200,1300)或临时固定的阀(1004,1104)。
