摘要： A welding apparatus having a welding tool and a weld cooling apparatus for forced cooling of the weld zone. The welding tool has a welding nozzle with a longitudinal axis, and the weld cooling apparatus uses a source of CO2 as the coolant. A coolant delivery conduit is arranged to move with the welding tool and has a first tube with a longitudinal axis that extends alongside the welding tool, and a second tube with a longitudinal axis extending downwardly and away from the welding tool. A coolant nozzle is located at the end of the second tube to eject coolant at the weld zone. The coolant nozzle outlet is spaced from the workpiece and arranged to direct a jet of coolant behind the welding tool onto the weld zone at least 10 mm from the longitudinal axis of the first tube.

摘要： A flexible sheet stacker is described which includes a support surface disposed substantially at right-angles to a flowline along which flexible sheets are fed in spaced relationship. The support surface is adapted to support in a stack the leading edges of the successive sheets fed along the flowline. The pressure-member is arranged to contact a face of a first sheet fed to the support surface and is thereafter movable away from the flowline against biasing means as sheets are progressively fed to the support surface. A wedge shaped separation member is movable along a substantially rectilinear path in advance of a sheet approaching the support surface, the separation member contacting the face of the stack and maintaining the contact during rectilinear movement of the separation means up to the support surface, a face of the stack being thereby displaced laterally out of the path of the leading edge of the approaching sheet as the sheet is advanced up to the support surface.
摘要翻译：描述了一种柔性片材堆垛机，其包括基本上与流线成直角设置的支撑表面，柔性片材沿着该线路间隔开地被馈送。支撑表面适于在堆叠中支撑沿着流动线路馈送的连续片材的前缘。压力构件布置成接触供给到支撑表面的第一片材的表面，并且随后片材逐渐进给到支撑表面，随后可将其从流动线移开以抵抗偏置装置。楔形分离构件可以在接近支撑表面的片材之前沿着基本上直线的路径移动，分离构件接触堆叠的面并且在分离装置的直线运动期间保持接触直到支撑表面，因此当片材前进到支撑表面时，堆叠件由此侧向移出接近片材的前缘的路径。

摘要： An infusion set (10,12) comprises a first part (10) housing a pump and control means and a second part (12) housing a replaceable infusate reservoir (14) with an integral infusion line (16). An anti-freeflow sliding member (26) has an opening (28) through which the infusion line (16) passes, and is slidable between a first open position and a second closed position by detaching the parts.
