Rotating guide tube

The fiiction is believed to have been caused by the buildup of sodium aerosol deposits on the inside of the liner tube and on the extension rod of the absorber in the cool region of the rotating shield, as shown in Figure 6.4. Lowering the rod moved the deposit on the guide tubes into the warmer region below the roof insulation where it melted off, reducing the friction. 

Figure 3.6 Rotational splitter. The falling stream impacts on the hopper (center panel) which guides the flux through the rotating tube (left panel) meeting, in this case, 32 chutes per rotation. The devise is engineered to be able to maintain a constant rotational velocity irrespective of the load. This feature allows for a vastly extended number of effective chutes by problem-dependent hopper flux versus rotational velocity coordination.

The left hand is used to support and rotate the former. The right hand supports the tube, holding it about half-way between the former and the remote end. This hand controls the angle between the mbe and the former, keeps the glass in the flame and guides it on to the forming tool. 

The polychromatic beam from the cold source is monochronaated by a helical slot velocity selector which selects neutrons of +1- 10% about a mean wavelength determined by the rotation speed of the drum. Typically, a mean wavelength of -0.525 nm is used. The neutrons are then collimated by a series of movable guides. Guide sections are inserted into, or removed from, the beam depending on the incident beam divergence required. A position-sensitive neutron detector is located inside an evacuated tube and can be moved to any distance between 1.1 and 35 m from the sample. 

The take-off tower consists of guide rolls, a steel nip (pinch) roll, and a rubber nip (pinch) roll. The guide rolls (or forming tent) collapse the bubble and guide the flattened film tube into the nip rolls. The steel roll is a driven roll which pulls the collapsed tube away from the die. The rubber rotates with the steel nip roll. Typical line speeds are 10 to 90 m/min (35 to 300 ft/min.). ...
