Patent DE-2522643-A1 (DE)
Title: Friction ring attached to roller bearing cage - is flexible and causes slow rotation of stationary rollers to prevent flats
Inventor: NEESE GERHARD
IPC: F16C33/46
Filed: 1975-05-22
Abstract: When a loaded roller bearing is stationary relative to a rotating shaft (3) on which it is mounted, the permanent contact pressure along the same line tends to produce flats on the rollers. To prevent the rollers from remaining stationary, the available radial play between the inner and outer race is used to produce a minute translatory motion on the rollers. This is achieved by attaching a radially flexible ring (8) to the roller cage (7). The outside face of the spring ring (8) is forced against the outer race of the roller bearing. The friction so produced is sufficient to drag the cage (7) and thus the rollers along in order to gradually change the contact positions of the rollers.

Title: Locking mechanism for e.g. doors - has housing with locking rotor operating locking element and overload friction coupling fitted between two
Inventor: UECKER ERWIN
IPC: E05B17/00
Filed: 1975-06-27
Abstract: The locking mechanism has a locking rotor connected to a locking element operated by carrier stub (12) which protrudes from housing (10). A head (14) with a wedge-shaped edge engages a lateral notch (13) in the element. Rotor contains the locking cylinder with internal face fitted with two blind holes with a pitch circle equivalent to the eccentricity of pin. If the cylinder is operated with the correct key, pin slides into one of the blind holes and this provides the rotary connection to the locking element (12). If forced rotation is attempted on the locking rotor (11), a spring loaded frictional connection comes into operation with the wedge-shaped head (14) being forced out from its seat (13) resulting in an axial movement of the head transmitted by the pin (17) onto the blocking (23) which prevents relative movement between the cylinder and the locking element, hereby protecting the cylinder tumbler pins from being shorn.-off.

Title: Reactive power compensator for supply networks - switches in capacitors according to harmonic currents and fundamental
Inventor: BIEGER FRITZ
IPC: H02J3/18
Filed: 1975-10-28
Abstract: The reactive power compensator, for supply networks, compensates for both fundamental and harmonic frequencies by switching capacitors to and from the network, and does so without the risk of overloading. The harmonic currents are measured and the result passed to the unit that controls the reactive power for the fundamental. The device that measures these harmonic currents can be a threshold switch, giving the simplest circuit. The output of the fundamental reactive power control unit and the output of the threshold switch are coupled via an OR-gate to the switching circuit so that the switchings of the latter are dependent on both outputs.
