摘要： A dilator for a teat of a dairy cow operates to facilitate the flow of fluid from the teat. The dilator has a body having a passage adapted to be positioned in communication with a duct of the teat. An elongated tubular member extends from the body into the duct. The tubular member has a passage allowing the flow of fluid through the dilator. A one-way valve mounted on the body allows the flow of fluid out of the dilator and restricts the entrance of external foreign substances back into the passage and duct of the teat. The valve has flexible side walls terminating in normally closed lips. A slit mouth is located between the lips. The slit mouth can be opened to facilitate the dispensing of medicinal compounds into the teat and udder of the mammal. An inserter having a rod extended through the one-way valve and tubular member is used to place the dilator in the teat duct and duct outlet, with the one-way valve located at the terminal end of the teat.

摘要翻译： 用于奶牛奶头的扩张器操作以便于来自乳头的流体流动。 扩张器具有主体，该主体具有适于定位成与奶头的管道连通的通道。 细长的管状构件从主体延伸到管道中。 管状构件具有允许流体流过扩张器的通道。 安装在本体上的单向阀允许流体从扩张器流出并限制外部异物进入奶嘴的通道和管道中。 阀门具有柔性侧壁，终止于常闭嘴唇。 嘴唇位于嘴唇之间。 狭缝口可以打开以便于将药物分配到哺乳动物的乳头和乳房中。 使用具有延伸穿过单向阀和管状构件的杆的插入器将扩张器放置在奶嘴管道和管道出口中，单向阀位于奶嘴的末端。

摘要： An apparatus for supplying aerosol fuel particles uniformly mixed with air to utilizer, as an internal combustion engine or burner. The apparatus has several fuel mixing and atomizing nozzles operable to mix one or more liquid hydrocarbon fuels and discharge the fuels through orifices in small fuel particles of uniform size. The fuel particles are mixed with air and flow through a pair of venturi throats with converging inlet walls and diverging outlet walls. The velocity of the air and fuel particles flowing through the venturi throats is at or above the speed of sound. The fuel particles are finely divided into particles between 0.5 and 1.5 micron in diameter as they move through the turbulent inlet and outlet interfaces of the air flowing through the nozzle throats at sonic and supersonic velocities and are evenly distributed into the air. The length or major dimension of one of the venturi throats is regulated with a baffle in accordance with the speed requirements of the engine.
