摘要： A valve guard assembly for a gas cylinder has a mounting collar 2 which is adapted to fit around and to engage the neck of the gas cylinder. The mounting collar 2 has an outer surface 6 in which there is an endless first coupling member in the form of a circumferential slot 8. A valve guard 10 has an integral coupling ring 12 with a second coupling member in the form of an endless inward projection 14 engageable with the circumferential slot 8. A means for acting against disengagement of the first and second coupling members is provided. This means takes the form of a locking band 30.

摘要： A laser cutting head includes a lens for producing a waist in a laser beam, an internal chamber having an inlet for pressurised gas, an outlet nozzle for both the laser beam and a jet of pressurised gas which communicates with the internal chamber, an inner hollow generally cylindrical lens holder which holds the lens. The lens holder has a body which (i) makes sliding engagement with an outer sleeve, (ii) holds the lens and (iii), in use, is axially displaceable away from the nozzle. A plurality of transverse pins extends through slots in the outer sleeve to engage the body of the lens holder, and an outermost adjustable limit ring the axial position of which is able to be reproducibly set, and which engages the sleeve, the adjustable limit ring defining the axial position of the lens holder.
摘要翻译：激光切割头包括用于在激光束中产生腰部的透镜，具有用于加压气体的入口的内部室，用于激光束的出口喷嘴和与内部室连通的加压气体射流，内部中空通常为保持透镜的柱面透镜架。透镜架具有主体，该主体（i）与外套筒滑动接合，（ii）保持透镜，和（iii）在使用中可远离喷嘴轴向移位。多个横向销延伸穿过外部套筒中的狭槽以接合透镜保持器的主体，以及最外面的可调节极限环，其轴向位置能够被再现地设定，并且其与套筒接合，可调极限环限定透镜架的轴向位置。

摘要： The invention relates to a nozzle (16) for emitting solid carbon dioxide particles. The nozzle (16) comprising an inlet (30) for receiving liquid carbon dioxide, a nozzle aperture (32) from which solid carbon dioxide particles flow from the nozzle (16), a duct extending between the inlet (30) and the nozzle aperture (32), the duct having a convergent section (36) and a divergent section (38), and an axially displaceable valve member (42) located within the duct, the valve member (42) having first and second convergent portions and a substantially cylindrical portion located between the first and second convergent portions. The nozzle (16) finds particular use in apparatus for cooling a heated weld zone in a workpiece.
