Abstract: An improved vacuum hose includes an axial vacuum conduit having outer linear buttresses integral with the conduit and arranged radially around the conduit; the buttresses are strengthened by substantially orthogonal ribs. Buttresses and ribs are imbedded in a matrix of flexible plastic which provides support and increases the collapse resistance of the conduit; the whole assembly is covered by a tough casing which may be a separate component or a treated surface of the matrix material.

Abstract: A pulsation dampener or desurger for use in sterile or other high-temperature applications such as food- or pharmaceutical-processing plants has an outer case surrounding a concentric perforated mandrel. Flanges or other connectors provide for attachment to a piping system so that product flows through the mandrel. Enclosing the mandrel is a liner of polytetrafluoroethylene or other fluoropolymer; the liner in turn is enclosed by a resilient sheath which may be integral with the liner. Between the liner and the mandrel is a pressure chamber which fluctuates in volume responsive to surges in line pressure, dampening the amplitude of the surges. Expansion of liner and sheath is limited by pressure within a gas chamber in the region between sheath and case.

Abstract translation: 用于无菌或其他高温应用的脉动阻尼器或去除器，例如食品或药物加工厂，具有围绕同心穿孔心轴的外壳。 法兰或其他连接器提供连接到管道系统，使得产品流过心轴。 封闭心轴是聚四氟乙烯或其他含氟聚合物的衬垫; 衬套又由可与衬套成一体的弹性护套包围。 衬套和心轴之间的压力室是响应于管线压力的浪涌而波动的压力室，抑制了浪涌的振幅。 衬套和护套的膨胀受到护套和外壳之间区域内的气室内的压力的限制。
