Patent DE-19650366-A1 (DE)
Title: Method for tensioning and supporting flexible roof with air cushion
Inventor: BOLTE DIETER
IPC: E04H15/20
Filed: 1996-12-05
Abstract: The method involves an integrated or self contained pressurised air cushion within the flexible structure. The reduction in noise is achieved by stopping the uncontrolled flapping of the sides and roof of a flexible structure. The air pressure can be constant or made to vary automatically to suit the conditions using commonly available components. No flapping means that rapidly fluctuating changes in pressure within the enclosed space are reduced. Heat insulation is achieved by the air cushion between lower and upper surfaces. Energy losses are reduced by air locks or treatment of the air in the air cushion.

Title: Adsorptive drying agent in shoe soles
Inventor: ZIMMERMANN WOLFGANG PROF DIPL
IPC: A43B13/42
Filed: 1997-04-02
Abstract: An hygroscopic or non-hygroscopic drying agent (d) in the sole of the shoe (a,f) absorbs fluid such as perspiration or leakage wetness and if hygroscopic condenses the water vapour e.g. by capillary condensation. The agent (d) should be contained in chambers (c) between inner (a) and outer (f) soles of the shoe, leaving enough free space in the chambers to allow the agent to swell as required. The agent remains stable throughout shoe life and remains capable of drawing in fluid repeatedly and giving this off on drying. Spent agent can be exchanged any number of times by a suitably shaped agent insert in the dismountable space between the soles (a and f). Otherwise the agent is pushed by a slide into the space between the soles and here closed off watertightly by a plug. Typical agents include activated carbon or bauxite (A1203). Area (e) presents a damping or cushioning layer.
