摘要： A material moving apparatus, and in particular, a material moving pump such as a manure pump. The pump includes a pumping chamber defined by interior chamber walls, and a piston or ram mounted for reciprocation in the chamber. The ram has side walls generally in conformance with the shape formed by the interior walls defining the chamber. The side walls of the ram are slotted or provided with grooves which induce turbulence in fluid flow between the side walls of the ram and the interior walls of the chamber to inhibit backflow of material from a position in front of the ram to a position behind the ram. The pump thus operates efficiently to pump material of low viscosity or material of low density.
摘要翻译：材料移动装置，特别是诸如肥料泵的材料移动泵。泵包括由内部室壁限定的泵送室，以及安装成用于在室中往复运动的活塞或活塞。压头具有通常与由限定腔室的内壁形成的形状一致的侧壁。柱塞的侧壁开槽或设置有凹槽，其引起流体在冲压器的侧壁和腔室的内壁之间流动的紊流，以阻止材料从冲头前部的位置回流到随机存取存储器。因此，泵有效地泵送低粘度的材料或低密度材料。

摘要： A method and apparatus for tentering nonwoven webs during annealing. The nonwoven web of thermoplastic fibers is restrained on a tentering structure at a plurality of tentering points distributed across an interior portion of the web, rather than just along its edges. The nonwoven web is annealed while restrained on the tentering structure to form a dimensionally stable nonwoven fibrous web, dimensionally stable up to at least the heatsetting temperature. The annealed nonwoven fibrous web is then removed from the tentering structure. In one embodiment, the tentering structure restrains the nonwoven fibrous web in a non-planar configuration during the annealing process. The tentering structure includes a plurality of tentering points projecting distally from a tentering support. The tentering points are positioned to be engaged with an interior portion of the web, thus restraining the web during annealing.
摘要翻译：一种用于在退火过程中拉伸非织造纤网的方法和装置。热塑性纤维的非织造纤维网被限制在横跨纸幅的内部分布的多个拉幅部分的拉幅结构上，而不是仅沿着其边缘。非织造纤维网被退火，同时被限制在拉幅结构上以形成尺寸稳定的非织造纤维幅材，其尺寸稳定至少达到热定型温度。然后从拉幅结构中除去退火的非织造纤维网。在一个实施例中，拉伸结构在退火过程期间将非织造纤维网限制在非平面构型。拉幅结构包括从拉幅支架向远侧突出的多个拉幅点。倾斜点被定位成与幅材的内部部分接合，从而在退火期间限制幅材。

摘要： A viscosity sensitive, pressure divider arrangement for use as part of an engine timing control tappet system where that system includes a block oil pressure supply, hydromechanical control valve and an oil sump, the pressure divider arrangement including an inlet chamber, a divider chamber and an exit chamber. The inlet chamber is connected to the divider chamber by means of a first connecting conduit having a relatively short length. The outlet side of the divider chamber is connected with the exit chamber by means of a second connecting conduit which has a length substantially longer than the length of the first connecting conduit. Additionally, the divider chamber includes a pressure-assist outlet aperture which is in flow communication with the hydromechanical control valve. The viscosity of oil flowing into the pressure divider arrangement will be acted upon by the combination of connecting conduits wherein the first connecting conduit is less viscosity sensitive than is the second connecting conduit. Consequently, a controlling pressure will be created within the divider chamber and this controlling (assist) pressure is communicated to the hydromechanical control valve and influences the switch point of that control valve.
摘要翻译：一种粘度敏感的分压器装置，用作发动机正时控制挺杆系统的一部分，其中该系统包括块油压力供应器，液压机械控制阀和油底壳，该分压器装置包括入口室，分隔器室和出口室。入口室通过具有相对较短长度的第一连接导管连接到分隔器室。分隔室的出口侧通过第二连接管道与出口室相连，第二连接导管的长度基本上长于第一连接导管的长度。此外，分隔器室包括与液压机械控制阀流动连通的压力辅助出口孔。流入分压装置的油的粘度将通过连接导管的组合而起作用，其中第一连接导管比第二连接导管的粘度敏感性低。因此，在分隔器室内将产生控制压力，并且该控制（辅助）压力传递到液压机械控制阀并影响该控制阀的切换点。

摘要： The invention relates to an air cleaner comprising a generally bell-shaped air cleaner housing and a generally frustoconical filter positioned concentrically within the housing. The housing has an air inlet at its small end and an air outlet at its large end for the flow of air generally axially into and out of the housing. The filter has a filter element coaxially juxtaposed the interior surface of the housing. The filter element is generally annular and has an upstream portion and a downstream portion. The downstream portion of a member supportably engages the upstream portion of the filter element. The upstream portion of the filter element has a diameter larger than the diameter of the member downstream portion. The member blocks the flow of air into the interior of the filter element and directs air axially along the exterior of the filter element. A downstream annular support piece engages the downstream end of the filter element. The support piece has an aperture communicating with the outlet and with the interior of the filter element. The support piece sealably engages the interior surface of the housing. Air flowing in an axial direction through the inlet passes over the member, axially along the filter element a distance before passing through into the interior of the element and axially out the outlet.

摘要： A flow controlling system having a viscosity sensitive means for producing a simulated fluid pressure which varies in correspondence with a fluid pressure at a predetermined portion of a fluid flow circuit on the basis of the viscosity of the fluid flowing through the circuit, and a pressure regulating means, that is responsive to changes in the simulated pressure, for maintaining a predetermined pressure at that predetermined portion of the fluid flow circuit. In particular, in a preferred embodiment of the invention, the flow controlling system is utilized in an engine timing control tappet system of the type having at least one expansible tappet for controlling timing of a fuel injector using oil that is supplied by a pump to an engine lubrication circuit.

摘要： A combination muffler and catalytic converter for an exhaust system. The unit comprises an outer housing having an inlet to receive exhaust gases, and a venturi is located within the housing and provides an aspirating effect to draw air into the housing from the atmosphere for the catalytic conversion. The venturi includes a diverging conical outlet section, and the gases are discharged from the outlet section through a plurality of perforations which aids in obtaining a uniform distribution of the gases to the catalytic unit that is located centrally of the housing. After passing through the catalytic unit, the gases are discharged from the housing through a discharge pipe having a closed inner end and perforations in its wall through which the gases flow. The perforated discharge pipe provides a self-controlling system which prevents overheating of the catalyst.
