Title: Hollow seal for movable window of car - has inflation of seals used to form tight fit with glass
Inventor: BALL WILFRIED
IPC: B60J10/75
Filed: 1991-06-14
Abstract: The door (1) for a passenger car has hollow profile seals (5, 6) running along the outer (10') and inner (10") walls at window level (10).

Title: Paper web pulse drying - has wet secondary blanket passing through heated press point to provide steam
Inventor: MAYER WOLFGANG
IPC: D21F3/02
Filed: 1992-05-15
Abstract: To extract water from a fibre web in a mechanical-thermal action, in papermaking, heat and pressure are applied simultaneously in a pressure gap on the web and at least one blanket. At least part of the evaporated water is extracted from the web by pulse drying, with a further pre-wetted sec. blanket to give the required steam. The paper web only comes indirectly into contact with the heated part of the assembly. At the sec. blanket, water can be substd. by another liq. with a lower boiling point. Before entry into the press point, the sec. blanket is wetted. At the press point, the surface on the side of the sec. blanket is heated. Both press units bearing against each other are rotating rollers, or one is static with a recirculating belt passing round it. A further recirculating belt can also pass through the press point, with heating at the belt on the side towards the secondary blanket. ADVANTAGE - The technique gives an effective drying action on the wet paper web, in a compact assembly, with low energy consumption, and without breaking up the fibre structure of the paper.
