摘要： A pipe coupling device for coupling the peripheral flanges of a pair of pipes together, including a pair of retainers with a V-shaped groove therein for receiving portions of the peripheral flanges of the pipes. The retainers are pivotally coupled at one of their ends by a hinge assembly and releasably coupled at their opposite ends by a latch mechanism. The hinge assembly has at least two links pivotally coupled at one of their ends to one of the retainers by a first pivot pin and pivotally coupled at their other ends to the other retainer by a second pivot pin. The pivot pins are separated from each other such that the links of the hinge assembly straddle the peripheral flanges of the pipes. This arrangement provides more uniform pressure at the ends of the retainers since the moment resulting from the offset of the hinge assembly is moved closer to the circumferential loading line between the retainers and the flanges of the pipe. In a second embodiment, the retainers are pivotally coupled together at one of their ends by a single pivot pin and releasably coupled together at their other end by a canted latch mechanism.

摘要： A fluid jet cutting system that includes an X-Y axis support table that is adjustable in both the X and Y-axis direction and has frame structures that overhang a centralized support platform assembly. The frame structures include overlapping central openings positioned above an opening defined by the platform assembly. A driving system such as a linear motor system shifts the support table. A Z-axis holder is provided for supporting a nozzle head assembly in a central area of the opening defined by the platform assembly. The nozzle head assembly has a main body that is fixed in position or limited to Z-axis movement with or without fourth and fifth axis rotation capability. Workpieces are supported by rails or the like within the open area. The nozzle head assembly directly receives abrasive through a plurality of abrasive ports which directly receive branch tubes of a multi-branch abrasive feed assembly. The fluid jet energy is conserved by the abrasive flow arrangement, the avoidance of lengthy tubing, the providing of uninterrupted high pressure fluid conduits, and a gas forced abrasive particle stream when particles are utilized. The avoidance of having the nozzle head assembly shift along an X-Y plane allows for a stationary catcher tank which can be rolled into and out of position on a roller carriage. The system further includes a filter which is internally positioned within an attenuator and bellville seal/return members provided in respective chambers of a dual action intensifier.

摘要： A pipe coupling device for coupling the peripheral flanges of a pair of pipes together, including a pair of retainers with gripping grooves therein for receiving portions of the peripheral flanges of the pipes. The gripping grooves of the retainers have a unique inner surface with a pair of slanted gripping surfaces and a pair of non-gripping surfaces that are located within the outer envelope of the peripheral flanges. This provides for lightweight, compact retainers. The retainers are pivotally coupled at one of their ends by a hinge assembly and releasably coupled at their opposite ends by a latch mechanism. The hinge assembly has at least two links pivotally coupled at one of their ends to one of the retainers by a first pivot pin being received in a pivot slot formed in the retainer and pivotally coupled at their other end to the other retainer by a second pivot pin being received in a pivot slot formed in the retainer. The pivot slots are open holes in some embodiments to reduce the weight of the pipe coupling device. The pivot pins are separated from each other such that the links of the hinge assembly straddle the flanges of the pipes. The latch assembly utilizes coupling members with tenons which are received in coupling slots formed in the retainers.

摘要： Fluid jet cutting system with nozzle assembly having a monolithic main body with a central fluid passageway with fixed diameter intermediate fluid jet passageway with orifice component at un upper end. The upper end of a modified focus tube is positioned directly below the outlet of the fluid jet passageway such that the enlarged opening at the upper end of the focus tube forms the mixing chamber. This avoids the high cost of mixing chamber wear inserts. The enlarged upper end opening has a diameter equal to or larger than a circumferential ring contacting the external most portion of the outlet of each of the preferably 3 or 4 abrasive ports spaced about the main body. The focus tube with mixing chamber enlargement avoids efficiency degrading abrasive contact with wall surfaces of the nozzle assembly. The abrasive ports extend from an upper, sloped surface of the main body to the abrasive ports outlet with the central axis of the abrasive ports forming an acute angle of less than 15 degrees. This angle minimization results in less efficiency degrading horizontal velocity components in the abrasive feed through the nozzle assembly, and also reduces surface wear contact in the main body since the abrasive ports dump the abrasive more along the central axis of the fluid filled fluid passageway and less into the side walls of the nozzle assembly and more into the fluid stream directly in a mixing region provided by the enlarged focus tube mixing chamber. The mixing chamber is preferably in the form of a deepened V configuration with a non-converging, uppermost section (e.g., a cylindrical section) having the largest diameter and a lower positioned converging section spaced below. The low wear features allows for the focus tube and main body to be formed of a material that is relatively less expensive than the high abrasion resistant material wear inserts.
摘要翻译： 具有喷嘴组件的流体射流切割系统具有整体主体，该主体具有中心流体通道，该中心流体通道具有固定直径的中间流体喷射通道，孔口组件位于上端。 改进的聚焦管的上端位于流体喷射通道的出口的正下方，使得聚焦管的上端处的扩大的开口形成混合室。 这避免了混合室磨损插件的高成本。 扩大的上端开口具有等于或大于圆周环的直径，该周向环与主体间隔开的优选3或4个研磨端口的每个出口的外部大部分接触。 具有混合室扩大的聚焦管避免了降低与喷嘴组件的壁表面的磨蚀接触的效率。 研磨口从主体的上部倾斜表面延伸到磨料口出口，磨料口的中心轴线形成小于15度的锐角。 这种角度最小化导致较低的效率降低了通过喷嘴组件的磨料进料中的水平速度分量，并且还减少了主体中的表面磨损接触，因为磨料口沿着流体填充的流体通道的中心轴线倾倒磨料，并且更少 进入喷嘴组件的侧壁并且更多地进入到由扩大的聚焦管混合室提供的混合区域中的流体流中。 混合室优选为加深V形的形式，其具有最大直径的非会聚的最上部分（例如，圆柱形部分），并且下部定位的会聚部分位于下方。 低磨损特征允许聚焦管和主体由比高耐磨材料磨损插入件相对较便宜的材料形成。
