Title: Interlocking concrete surface slabs for roadway - have a vertical bonding between one another to form even traffic surface
Inventor: LANGSDORFF FRITZ
IPC: E01C5/06
Filed: 1972-03-21
Abstract: The concrete blocks can in one form have a quadratic shape (101) on whose upper side (10) there are two dummy joints (12, 14) extending at right angles to a further pair of such joints so that the block surface is divided into nine fields. Similar dummy joints (e.g. 22, 24) are formed on the bottom surface but displaced laterally from the upper joints by a short distance (A). In this way a safety zone (30) is formed between the upper and lower sets of joints and is inclined at an angle (theta) to the normal to the upper side. The angle chosen depends on the thickness of the blocks, the depths of the joints and the magnitude of the lateral displacement (A).

Title: Vibration stabiliser for high-speed rotor - has damping ring revolving with rotor without any contact with surroundings, used e.g. in centrifuges
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: B04B9/12
Filed: 1973-03-23
Abstract: An apparatus for stabilising the movements of a very high speed rotor, which has >=1 bearing where the rotor is centered by magnetic forces without any mechanical contact with its surroundings, consists of a damping system in which the necessary damping forces are applied to the rotor partially or completely by mechanical and/or hydraulic and/or hydropneumatic forces. Pref. these damping forces are applied to the rotor by a damping system which is mechanically connected to the rotor and therefore revolves with it, but which has no mechanical connection with the surroundings. Used in very high speed centrifuges, e.g., revolving at 1,000 rpm, for the spindles of spinning machines or high speed revolving wheels in satellites. By the positive mechanical connection between the stabilising ring and the rotor, a much greater damping force is produced than with a purley magnetic coupling. This result is achieved by the basic principle of having a portion at least of the damping device revolving with the rotor.
