Title: Tyre supporting folding element - with pressure fluid inlet to ease detachment
Inventor: ZEMME FRANZ
IPC: B29D30/06
Filed: 1979-01-08
Abstract: The Parent Patent described a folding membrane which is applied to the inside of a tyre under pressure during the heating operation. this has now been equipped with ducts between the inner wall of the tyre and the outside of the membrane. A fluid under pressure can be admitted through them when the folding membrane is to be extracted. The folding membrane is secured in the fixture inside the tyre.

Patent DE-2916178-A1 (DE)
Inventor: SCHMIDBERGER RAINER DIPL PHYS
IPC: G01N27/12
Filed: 1979-04-21
Abstract: A sensor measuring the partial oxygen pressure in furnace exhaust gas has an active layer of palladium. When the sensor is maintained at a particular temperature, for example about 700 DEG  C., the palladium changes to palladium oxide at a specific air number, namely 1.2. The change from palladium to palladium oxide and vice versa causes a change in conductivity by a factor of approximately 20. This change in conductivity is a clearly defined output signal which can be adjusted to occur at any desired air number in the region from 1.05-1.4, depending upon the temperature at which the sensor is maintained. Two sensors may be used, each maintained at a different temperature so that a control region is defined as the air number region wherein the sensor maintained at the lower temperature is oxidized while the second sensor is reduced. Preferably, the active layer consists not only of the metal oxide but also of a ceramic component such as cerium oxide which is doped with 0.5-10% by volume of Nb2O5 or Ta2O5.

Title: Vibration damper with spring - has fluid transmission with primary and secondary bellows of different cross=section accelerating swing mass
Inventor: BRAUN DIETER DIPL ING DR
IPC: F16F9/10
Filed: 1979-12-20
Abstract: The vibration damper comprises a spring between the vibrating part and the holder and a swing mass which moves inside a fluid transmission to suit the movement of the protected part. Fluid transmission is provided by a primary fluid space deforming in the vibration sense and a second space which also deforms in this direction, but is smaller in cross-section, and thus deforms mor strongly. This accelerates the serving mass so that inertia changes the pressure in the fluid and produces a dynamic force which compensates the dynamic component of the force transferred to the holder by the spring. The second fluid space may adjoin the first one with a low-leakage connection between, or the second one can be inside the first space and sealed to contain a compressible medium at over- or under pressure. The second space can be linked to atmosphere. The first space may have a deformable and a smaller fixed section, enclosing part of the second space and forming a fluid ring. A preset spring engages the mass and the holder to raise fluid pressure but without increasing fluid volume during operations.
