A tool-less adjustable torque setting assembly for a bottle capping headset wherein there is a witness mark and a push button. The operator pushes in the button and a tooth on the button's inside surface of the housing disengages with the inside wall of the housing where there are a series of mating teeth. The assembly is rotated to the desired setting and released. The button, which is spring loaded, will return to the seated position in the series of teeth within the housing. No tools are required to adjust the torque setting.

An apparatus for automated capping and de-capping of test tubes having an ejector pin system for individualized cap ejection.

Methods and apparatus for rotating a container delivered to a container manipulation system on a conveyor are described. In some embodiments, first and second carriages are positioned on opposite sides of the conveyor, each carrying respective forward and rear clamp arms. Each clamp arm is selectively independently moveable and carries at least first and second vertically spaced-apart wheels. All of the wheels are engageable with the container on the conveyor. At least two wheels on the first carriage are power-driven and selectively rotatable. The remaining wheels are free-spinning. Additional methods, systems and apparatus are also disclosed.

The invention relates, inter alia, to an apparatus for closing a container, comprising a closure element, a pre-tensioning device with at least one elastic, pre-tensioned element for specifying a head pressure and a lifting cam follower for following a lifting cam. The lifting cam follower is connected to the closure element via the pre-tensioning device for vertically moving the closure element when following the lifting cam. The at least one elastic, pre-tensioned element is arranged substantially at the same height as the lifting cam follower or above the lifting cam follower. Alternatively, it is provided that a vertical extension of the at least one elastic, pre-tensioned element along a vertical axis and a vertical extension of the lifting cam follower along the vertical axis overlap or adjoin one another.
