Abstract: A wheel apparatus is provided for measuring by rolling contact a dimension of an elevated temperature surface. The device is particularly useful for measuring the length of product in a continuous casting machine. The apparatus includes an elongated arm having an internally cooled wheel rotatably mounted at one end thereof. The arm is pivotally movable about a mount at an end of the arm opposite from the one on which the wheel is mounted. The mount biases the arm to a position in which the longitudinal axis of the arm is normal to the adjacent surface of the cast product. The biased mount permits pivotal deflection of the arm upon contact of the wheel by cast product moving in either a forward or reverse direction. The arm has at least one longitudinal cooling fluid passage which only registers with a cooling fluid supply passage in the arm mount when the arm is in the deflected positions thereof. Generally, air is supplied through the mount to cool the arm and outer surface of the wheel.

Abstract: A body of pulverulent material is confined in a receptacle, and a screw conveyor having a vertical axis conveys a predetermined quantity of the material per unit of time in the upward direction. The amount of the pulverulent material which is being conveyed is such that it fills the space between the turns of the helical conveyor screw of the screw conveyor, which is surrounded by a jacket, only in part, thus leaving a passage in the screw conveyor through which a stream of drying air is conveyed in contact with the pulverulent material so that the drying air withdraws moisture from the material. The rotational speed and/or the pitch or spacing of the consecutive turns of the conveyor screw is so selected that only such an amount of the pulverulent material enters through an opening in the jacket of the screw conveyor while the space between two consecutive turns is juxtaposed with the opening as to only partially fill such a space.

Abstract: A paper machine multiple cylinder dryer includes a plurality of drying cylinders, in conjunction with which a drying fabric supports the web as it moves from one cylinder to another in closed conduction. A supporting fabric supports the web on some of the cylinders. The runs of the web supported by the drying fabric, the free surfaces of the drying cylinders and the runs of the supporting fabric confine elongated pockets in conjunction with the cylinders. In order to prevent web breaks occurring in the drying section of the fast-running paper machine, since such breaks are among the most important factors limiting the increasing of paper machine speeds, the multiple cylinder dryer provides a pressure greater than the ambient atmosphere pressure in the pockets in the direction of travel of the web, at least in the initial part of the dryer. This results in the considerable stabilization of the running of the web.
