摘要： A rotomolded hydraulic oil tank includes an integral dividing baffle which strengthens the tank structure, and diverts and slows returning oil for better air removal and oil mixing. This occurs by positioning the dividing baffle so that the top of the baffle is just below the oil level in the tank so that returning oil must flow a greater distance around the baffle at a reduced velocity thereby increasing the time the oil is in the tank before exiting the tank through the tank suction. The lower velocity of the oil and the increased passage time allows air in the returning oil more time to float to the surface of the oil in the tank.
摘要翻译：滚塑液压油箱包括一个整体分隔挡板，加强了油箱结构，并转向并减缓了返回的油，以便更好地除气和油混合。这通过将分隔挡板定位成使得挡板的顶部刚好低于罐中的油位，使得返回的油必须以减小的速度在挡板周围流动更大的距离，从而增加油在罐中的时间通过油箱抽吸离开油箱。油的较低速度和增加的通过时间允许返回的油中的空气更多的时间漂浮到罐中的油的表面。

摘要： In general, the invention relates to an improved assembly for insertion of an intravenous catheter and method of insertion which minimizes or eliminates the potential for exposure to blood and other bodily fluids during the use and insertion of an intravenous catheter. An intravenous catheter hub has a side opening directly to connected to a port of a multi-port stopcock. A modified syringe and hollow-bore needle are attached directly to the base of the catheter and when properly inserted, the needle extends slightly beyond the tip of the catheter. After the needle is inserted beneath a patient's skin, the syringe is used to generate slight negative pressure so that blood immediately flows into the syringe as soon as a vein is punctured by the needle. The syringe is then removed and the flow of fluids into the patient may be regulated by the multi-port stopcock.
摘要翻译：通常，本发明涉及用于插入静脉内导管的改进的组件和插入方法，其在使用和插入静脉内导管期间最小化或消除了暴露于血液和其它体液的潜力。静脉导管座具有直接连接到多端口旋塞的端口的侧开口。改进的注射器和中空针针直接附接到导管的基部，并且当适当地插入时，针稍微延伸超过导管的尖端。在将针插入患者皮肤之后，注射器用于产生轻微的负压，使得一旦静脉被针穿刺，血液立即流入注射器。然后取出注射器，流体进入患者的流量可以由多端口旋塞阀调节。

摘要： A lift boom assembly includes a pair of lift arm assemblies. Each of the lift arm assemblies include a main lift link with a rear end portion and a second lift link. The second lift links each have a first end portion, a second end portion pivotally connected to a frame of a work machine to define a first pivot, and a central portion pivotally connected to the rear end portion of a respective main lift link to define a second pivot. A pair of control links each having a first end portion that is pivotally connected to the frame of the work machine to define a third pivot. A second end portion of the control links being pivotally connected to a respective one of the main lift links to define a fourth pivot with each of the first, second, third, and fourth pivots being located above the lower portion of the frame. The pivots of the components are located on an upper portion of the work machine so that the components cooperate together to achieve a simple and efficient lift boom design.
