Title: Paper web drying section
Inventor: STEINER KARL DR
IPC: D21F5/02
Filed: 1997-12-13
Abstract: The web drying section, of a paper-making machine and the like, has a constant pressure difference as much as possible between the common feed (4) and exhaust (6) for the heating medium.  Most of the channels (3) linking the feed (4) to the drying cylinders (1), and preferably all of them, have a given and set throttling of the heating medium pressure. The pressure difference between the feed (4) and exhaust (6) is the product of the drying cylinder (1) radius and 10<4> N/m<2>. The channel (3) linking the heating feed (4) to the drying cylinder (1) has a reduced inner diameter, preferably of 2-7 cm and/or a perforated diaphragm as the throttle (7). A controlled pressure valve is in the heating feed (4) to the drying cylinder (1). The throttling action is set according to the dry content of the web being processed at the corresponding drying cylinder (1), and pref. increases with a rising dry content.  The throttling action is also set according to the angle by which the web passes round the drying cylinder (1), and is lessened with a larger angle round the cylinder. The separate heating medium feed (3) and exhaust (5) channels for each cylinder (1) are linked to a common feed (4) and exhaust (6) for the cylinder row,

Patent DE-19813535-A1 (DE)
Inventor: MOL JOHANNES C F G VAN
IPC: B66D5/04
Filed: 1998-03-27
Abstract: The invention relates to a braking device for a body which is moved in a translational manner by a rotor-driven power transmission element. Said body is, for example, a work platform and/or an elevator cab of a platform for lifting persons whose height can be adjusted along a pole by at least one driving pinion (10), said pole comprising a toothed rack which meshes with the driving pinion (10). The inventive device comprises a shaft (7) which is rotationally mounted in a housing (2), and a brake lining support (22). The brake lining support has at least one brake lining (23) and is connected to the shaft (7) in a rotationally fixed manner. The brake lining interacts with a fixed brake surface (24) during braking. The braking device also comprises an initiating device which moves the brake liner support (22) between a non-braking and a braking position. The invention provides a braking device with which a relative velocity between the shaft (7) and the brake liner support (22) does not need to be equalized during braking action due to the production of an effective brake which does not wear easily. To this end, the initiating device is constructed as two parts and is comprised of a centrifugal weight support (11) having at least one centrifugal weight (12). The initiating device is also comprised of an actuating element (21) which moves the brake liner support (22) into the braking position, is connected to the shaft (7) in a rotationally fixed manner, and decouples from the centrifugal weight support (11) during braking action. The centrifugal weight support (11) is connected to the actuating element (21) in such a way that a coupling resulting from a difference in speeds between the centrifugal weight support (11) and the actuating element (21) opens in a nondestructive manner due to the application of an inertial force.

Title: Papermaking machine press section
Inventor: MESCHENMOSER ANDREAS
IPC: D21F3/04
Filed: 1998-10-20
Abstract: The press roller (20) at a papermaking machine, to apply pressure to a web of paper or cardboard, has a mantle (40) rotating round a fixed carrier (38), with a mechanism (44, 46) to set the bending action of the roller carrier (38).

Title: Making reeled flexible tubing and coaxial cables with exceptional properties, is achieved without kinking or waviness, by traveling ice plug technology in which local carbon dioxide solidification is induced
Inventor: FREYHARDT HERBERT C
IPC: B21C47/02
Filed: 1998-11-18
Abstract: The start (5) of the closed tubing (2) is hermetically-sealed, connected internally to a valve (6) and secured to a spool (4). Pressurized gas is fed in through the valve to fill and pressurize the tubing. Internal pressure is maintained. Downstream of production, the tubing enters a freezing unit, where the gas is solidified, forming a plug seal filling the internal cross section. At the same time, the tubing is wound onto the spool.  Preferred features: The gas is frozen sufficiently to form an axial, gas-tight plug. The gas can be frozen in three separate chambers of the freezing system, spaced along the production line. This forms three gas-tight plugs. Each is effective only over a limited time scale. The gas is carbon dioxide. Before and after each freezer, the tubing is heated. Gas is supplied through a rotary joint (8) in the hollow core (7) of the spool (4). Its pressure is given by: P = A \* D \* W/R<2> , A being a constant dependent on the tubing material, D the tubing diameter, W the wall thickness, and R the radius of curvature. The tubing is closed at its end during unspooling, internal gas pressure being maintained.
