Mineral wool filler and silencer moulding for car exhausts

Where the surface (4) of the moulding (1) adapts to contained pipe or tube, the mineral wool should be sealed in fibre-binding heatproof noncombustible material such as a solidified waterglass solution or else by a solution sprayed on and allowed to solidify. The sealing solution can also be applied by immersion or by pressurised impregnation. The mineral wool moulding can be stabilised throughout by means of a thermoplastic binder and in any case sealed all over its surface. The outer surface (6) of the moulding should be coated in foil, fabric or netting. The moulding can be sprayed with the waterglass solution during its manufacture. The filler may consist of several parts so all together pack out the interval between tubes etc. and housing.

The mounting portion (102) is secured to the fuel conduit (40), and the damping portion (104) includes a stack (130) of damping washers (132), a bushing (150) on top of the stack (130) of damping washers (132), a spring clip (140) secured around the stack (130) of damping washers (132) and the bushing (150), and a shoulder bolt (160) disposed through the bushing (150) and the stack (130) of damping washers (132) and engaged to the mounting portion (102).

一种hdpe管刚性预埋件连接组件

本发明提供了一种HDPE管刚性预埋件连接组件，属于管件技术领域。本HDPE管刚性预埋件连接组件，包括预埋件和伸缩节，所述的预埋件与伸缩节之间通过管道连接件连接，所述的预埋件通过电熔卡箍与管道连接件的上端连接，所述管道连接件的下端插入进伸缩节中，所述的预埋件包括呈圆柱状的本体，所述本体的内部设置有环形金属套，所述伸缩节的上端为呈喇叭形的第三管口，所述第三管口的外壁上开设有外螺纹，所述的外螺纹外连接有管盖，所述的伸缩节与管道连接件之间设置有密封圈。本发明通过加装环形金属套和伸缩节可以使HDPE管刚性预埋件在穿过楼板时不会产生环向收缩，而出现轴向收缩时具有适度的补偿空间。

Helical Strake Attachment for Tubular Structural Members

A helical strake pole system that includes a tubular pole having a longitudinal axis and threaded attachment points. The system further includes a helical strake fin disposed circumferentially around a portion of the tubular pole along the longitudinal axis. The system further includes couplers disposed on the tubular pole. The couplers are configured such that each coupler has a first portion with a slot configured to receive an upper portion of the helical strake fin and a second portion configured to removably coupled to a threaded attachment point of the tubular pole. In addition, each coupler is configured to position a portion of the helical strake fin substantially perpendicular to a surface of the tubular pole.
