    • Apparatus for manufacturing cylindrical tubes from paper or similar fibrous materials. A layer of plastics material which becomes tacky when heated provided on a paper web is heated through the paper web then pressed against a plastics foil web with one edge of the plastics foil web extending beyond the corresponding edge of the paper web. The joined webs are wound helically onto a mandril with the extended edge of the plastics foil web overlapping a corresponding opposite second edge of the plastics foil web. A string of molten adhesive is applied along the extended edge on the mandril. The mandril is cooled to maintain the foil layer nearest the mandril below its melting temperature.
    • 用于从纸或类似纤维材料制造圆柱形管的装置。 一层塑料材料,当被加热设置在纸幅上时变粘,加热通过纸幅然后压在塑料箔片上,塑料箔片的一个边缘延伸超过纸幅的相应边缘。 连接的纤维网螺旋地缠绕在心轴上,塑料箔片的延伸边缘与塑料箔片的相应的相对的第二边缘重叠。 一串熔融粘合剂沿着延长的边缘施加在心轴上。 将曼荼尔冷却以使箔层最靠近其熔融温度以下。

    • An apparatus for taking a sample of a toxic and/or radioactive substance byntroducing such substance into a sample vessel. The apparatus includes a rotatable cylinder containing a recess for receiving a sample vessel. A drive shaft is connected to the cylinder for imparting rotary and axial movements to the cylinder for moving the recess of the cylinder between first and second positions. A needle head filling system is arranged above the cylinder at the first position for filling a sample vessel with toxic and/or radioactive substances. The cylinder is lifted by the shaft for engagement with the needle head filling system when being filled and lowered by the shaft after being filled. An inlet and outlet conduit is provided having one end for receiving from and discharging into the recess of the cylinder a sample vessel, the one end being located above the cylinder at the second position. A stripper is located between the cylinder and the needle head filling system for disengaging the sample vessel from the needle head filling system when the cylinder is lowered by the shaft after being filled.
    • 一种用于通过将这种物质引入样品容器中来获取有毒和/或放射性物质样品的装置。 该装置包括可旋转的圆筒,其容纳用于接收样品容器的凹部。 驱动轴连接到气缸,用于向气缸提供旋转和轴向运动,用于在第一和第二位置之间移动气缸的凹部。 针头填充系统布置在气缸上方的第一位置,用于填充具有有毒和/或放射性物质的样品容器。 在被填充之后,当轴被轴被填充和下降时,气缸被提升以与针头填充系统接合。 入口和出口导管设置有一端,用于从气缸的凹槽中接收和排出样品容器,一端位于第二位置的气缸上方。 汽缸和针头填充系统之间设有一个汽提器,用于当汽缸在充满后由轴下降时,将样品容器与针头填充系统脱开。
