    • A process for the minimization of phosphonium ion ligand degradation products formed during reaction of a polyunsaturated olefin or an unconjugated functionalized olefin in the presence of a transition metal-triorganophosphine ligand complex catalyst to form as a product, by-product, or intermediate product a conjugated functionalized olefin having a carbon-carbon double bond conjugated to an α-electron-withdrawing group, such as, an α,β-unsaturated aldehyde, ketone, ester, acid, or nitrile. The minimization process involves conducting the reaction under selected conditions of conversion, temperature, pressure, or a combination thereof; and/or by selecting a triorganophosphine ligand with a specified steric and/or electronic property. Further, a process for reversion of phosphonium ion ligand degradation product(s) back to useful triorganophosphine ligand(s), the reversion involving treating a reaction product fluid containing the degradation product(s) with an inert gas, hydrogen, synthesis gas, or a mixture thereof under conditions sufficient to regenerate the triorganophosphine ligand(s).
    • 一种在过渡金属 - 三有机膦配体催化剂存在下,在多不饱和烯烃或非共轭官能化烯烃反应期间形成的鏻离子配体降解产物最小化的方法,以形成产物,副产物或中间产物,共轭 具有与α-吸电子基团例如α,β-不饱和醛,酮,酯,酸或腈共轭的碳 - 碳双键的官能化烯烃。 最小化方法包括在选择的转化条件,温度,压力或其组合下进行反应; 和/或通过选择具有特定空间和/或电子性质的三有机膦配体。 此外,将鏻离子配位体降解产物还原回有用的三有机膦配体的方法,涉及用惰性气体,氢气,合成气体或其混合物处理含有降解产物的反应产物流体的逆转 其混合物在足以再生三有机膦配体的条件下进行。

    • A rolling shutter characterized by an array of edge-adjacent, parallel shutter slats and full shutter width, clear shutter segments or links articulately interconnecting respective pairs of adjacent shutter slats. The links are telescopically movable in the slats to permit relative movement of the slats between spaced-apart and juxtaposed positions. When spaced apart, the slats form therebetween a gap which exposes the clear link which permits passage of light over substantially the full extent of the gap. The clear links also provide a double hinge-like joint between adjacent slats. The shutter slats are also uniquely reinforced and have an improved exterior appearance.
    • 一种滚动快门,其特征在于具有边缘相邻的平行快门板条和全快门宽度的阵列,清晰的快门部分或链接铰接地互连相应的相邻的快门板条对。 连杆在板条中可伸缩移动,以允许板条在间隔开和并列位置之间相对移动。 当间隔开时,板条之间形成有间隙,该间隙暴露清除链节,允许光在空隙的基本上全部范围内通过。 清晰的连接还提供了相邻板条之间的双铰链状接头。 快门板条也是独特的加强,并具有改进的外观。

    • A fluid coupling of the type which couples automatically on the engagement of two coupling members and which uncouples automatically on the application of a predetermined minimum axial separation force, as is useful in refueling operations between moving vehicles. One coupling member has an annular groove about its outer surface, and the other carries at least one locking ball which may be held in engagement with the groove by a lock ring having graduations in internal diameter. Applying a tensile force between the coupling members compresses a spring and simultaneously displaces the lock ring with respect to the ball until an unlocked position is reached, allowing uncoupling by release of the ball from the groove. Uncoupling may also be effected manually and independently of the tensile force applied, and there is a convenient adjustment of the threshold force necessary for uncoupling. The coupling preferably includes automatically operable valves to prevent loss of fluid on uncoupling, and is almost completely pressure balanced, to provide for consistent and reliable operation and very little change in operating characteristics over a wide range of fluid pressures.
    • 这种类型的流体联轴器在两个联接构件的接合上自动联接,并且在施加预定的最小轴向分离力时自动脱开,如在移动车辆之间的加油操作中有用的。 一个联接构件具有围绕其外表面的环形槽,而另一个承载至少一个锁定球,其可以通过具有内径刻度的锁定环保持与凹槽接合。 在联接构件之间施加张力压缩弹簧并同时使锁环相对于球移动,直到达到解锁位置,从而允许通过从凹槽释放球而脱开联接。 解偶合也可以手动地实现,而不受施加的张力的影响,并且对于解偶联所需的阈值力有方便的调整。 联接器优选地包括可自动操作的阀,以防止解耦时的流体损失,并且几乎完全是压力平衡的,以提供一致和可靠的操作,并且在宽范围的流体压力下操作特性的变化很小。
