A Yankee dryer is a pressure vessel used in the production of machine glazed (MG) and tissue paper. On the Yankee dryer, the paper goes from approximately 42–45% dryness to just over 89% dryness. In industry, MG cylinders or Yankee dryers are primarily used to remove excess moisture from pulp that is about to be converted into paper.

The 7200 Series is a critical care ventilator model prior to the 760 Series. [15] 560 Series. The 560 Series is a portable ventilation unit. [16] Bennett MA-1
The same fitting can be used in reverse as an eccentric increaser or expander. They are used where the diameter of the pipe on the upstream side of the fitting (i.e. where flow is coming from) is larger than the downstream side, and where there is a danger that vapour may accumulate. [1]
Mentor Corporation was founded in Minneapolis, Minnesota in 1969 by Christopher Conway, Eugene Glover, and Thomas Hauser. [5] [6] Mentor went public in 1970 and its first product line consisted of electronic laboratory instruments for the detection and measurement of the electrical activity of nerve cells and neural systems. Special urethral ...
Tissue expansion is a common technique used for breast reconstruction. [20] This essentially involves expansion of the breast skin and muscle using a temporary tissue expander. [21] Three to four weeks after the mastectomy, a saline solution will be injected into the expander to gradually fill it. This process is supported by a tiny valve ...
Tissue supported expanders allow the forces to be applied directly to the tissues of palatal mucosa instead of teeth. The most common type of tissue-borne expander is known as the Haas Appliance. This appliance was popularized by Andrew Haas in 1961. This appliance involves bands placed on maxillary first premolar and first molars on each side.
One side is connected to the pipe work of the heating system and therefore contains water. The other, the dry side, contains air under pressure, and normally a Schrader valve (car-tire type valve stem) for checking pressures and adding air when needed. When the heating system is empty or at the low end of the normal range of working pressure ...
