The present invention is to be used in drying installations. The invention consists of combining the heat of the copper cylinders on which the paper slides with pressing rollers with a diameter larger than the conventional rollers used to transport the belt which guides the sheet of paper. The invention has been foreseen to increase the number of pressure points by installing other pressing rollers at the free spaces, accelerating the drying process.

An intranasally applicable powdery pharmaceutical composition comprising a polypeptide having a physiological activity, a quaternary ammonium compound, and a lower alkyl ether of cellulose. This powdery pharmaceutical composition has an excellent preservability and chemical stability of the polypeptides and, when the powdery composition is administered to the nasal cavity in the form of a spray, the polypeptides are effectively absorbed through the nasal mucosa.

A support bracket has a base member adapted for attachment to a particular measuring tool and a vertical member extends from the base member and it has a horizontal slot within its top edge which mounts a tape rule by way of the tape rule spring clip. The tape rule is oriented on the support bracket such that measurements may be made along a common baseline with reference to the measuring tool and a workpiece to be measured while, at the same time, measurements may also be made along a ruler edg...
