Patent DE-2457229-A1 (DE)
Title: Hose-type door seal with expanding sealing element - fitted along entire door circumference, with actuating mechanism on one side only
IPC: E06B7/23
Filed: 1974-12-04
Abstract: The arrangement does not need a fixed door frame, the endless expanding hose fitted in the peripheral groove of the door leaf provides the function of the sealing against the side faces of the opening to be sealed-off. On one of the door leaf edges a slat is provided behind the hose, which can be moved on wedge-shaped guides longitudinally, but at the same time compressing the length of hose in contact with the slat. On this part of the door circumference seal is achieved by pure mechanical pressure of the resilient hose against the edge surface of the opening, the rest of the hose is now inflated by the compressing action of the slat and the inflated hose provides the seal.

Title: Plant using heat generated by burning urban waste - feeds heat to compressor delivery of gas turbine
Inventor: STRACH LOTHAR
IPC: F02C7/08
Filed: 1975-01-02
Abstract: Plant using heat generated by burning urban waste employs this heat to supplement the fossil fuel supplied to a gas turbine engine. Between the compressor and the combustion chamber of the engine there is arranged a recuperator fed by the hot combustion product of the waste-burning boilers to raise the temperature of the compressor delivery and thereby reduce the amount of fossil fuel necessary to raise the turbine entry temperature of the engine to the level required to efficient operation. The engine is connected to an electricity generator to be used e.g. for charging the batteries of electrically driven coaches.

Title: Plastics cladding for reinforced concrete components - has ribbed sections with split edge ribs connected by channel section clamp
IPC: B28B7/36
Filed: 1975-03-07
Abstract: The lining, preferably for reinforced concrete components, is made of ribbed plastics sections whose parallel T shaped ribs are readily embedded into concrete. The lining sections have split ribs at their edges which join to form complete ribs.

Title: Bottle screw cap seal - has combined sealing and security rings for ease of assembly
Inventor: HEINLEIN HANS
IPC: B65D41/34
Filed: 1975-04-24
Abstract: The bottle (3) screw cap (1) is taper grooved (11) and lipped (13) to receive a flexible plastic sealing ring (7) correspondingly shaped for retention after insertion.
