Abstract: A gas laser emits an output laser beam from a low pressure region to a region having a higher pressure. This is done through an opening in the side of a laser device. Under normal circumstances, the provision of such an opening would incur a flow of air from the high pressure side, externally of the laser device, to the low pressure side within the device. To prevent this, an aerodynamic window is placed in a passageway leading from said opening in the laser device through which the laser beam passes. A gas flow is passed across said passageway which will provide a flow which represents the flow of a segment of a free-vortex flow field having a pressure differential across the segment which is equal to that between the low and high pressure regions. A single nozzle, specifically contoured to produce a segment of a free-vortex flow field directs the gas into the passageway and an opening collects the flow onto the other side of said passageway. A method of constructing such a nozzle is set forth.

Abstract: For mounting and dismantling a resilient liner of a pressing roller of a draft-frame in textile machinery preparatory to spinning, a method is suggested which comprises the steps of positioning the liner on a temporary supporting member, inserting the roller into the liner with a snug fit while simultaneously slipping the temporary supporting member away.

An apparatus for performing these operations quickly and conveniently is also described. The method and apparatus in question permit to dispense with adhesives for fastening the resilient sleeve to its own supporting member, and affords the possibility of removing the resilient layer without damaging the roller in any wise.
