Title: Key container with pivot-out flat key
Inventor: LINDMAYER MARTIN DIPL ING
IPC: E05B19/04
Filed: 1989-01-28
Abstract: The invention relates to a key container with a pivot-out flat key, which, as an L-shaped receiving shaft, is let into a corner region and an adjoining length region of a front edge and a side edge of a bar-shaped housing and in whose shorter leg the flat key is attached via its grip part angled off from the shaft part, as a result of which, in the non-use position of the flat key, the grip part engages into a length portion of the leg which is in the vicinity of the corner and, in the use position, it engages into a length portion of the leg which is remote from the corner. In order that, during storage of the key container, foreign bodies cannot penetrate into the length portion remote from the corner, the latter is covered, with the flat key in a sunken position, by an end portion of the grip part, which is articulated on the housing approximately in the centre of its length, and the shorter leg of the receiving shaft is sunken corresponding to the pivot length of the end portion.

Patent DE-4010989-A1 (DE)
Title: Concrete for floor with underfloor heating - is made from sand, cement, water and steel fibres to increase thermal conductivity
IPC: F24D3/12
Filed: 1990-04-05
Abstract: The underfloor heating consists of pipes embedded in a floor made from a mixture of sand, cement and water with the addition of steel fibres. These steel fibres increase the thermal conductivity of the concrete so that the room is more rapidly heated. The quantity of steel fibres can be varied to vary the thermal conductivity of different parts of the floor. In the area where the pipes are led into the room and the water is at its highest temperature the thermal conductivity is at its lowest. Where the pipes lead out of the room and the water temperature is lowest, the thermal conductivity is highest. The heat input into the room is thus uniform over the floor surface.
Patent DE-4012087-A1 (DE)
Title: Timer controlled measurement signal processing - using separate filtering, averaging and digitising of opposite polarity half waves for optimised signal-noise separation
