Patent DE-4210042-A1 (DE)
Inventor: FREMEREY JOHAN K
IPC: F16C17/20
Filed: 1992-03-27
Abstract: The invention concerns an auxiliary bearing system with mechanical bearing elements (3, 4), the auxiliary bearing system being designed for a rotor (2) which is mounted for contactless motion in a stator (1), in particular by means of a magnetic field between the rotor and stator. The auxiliary bearing elements are fixed to the stator at a short radial distance from the rotor and become active in the event of the rotor jumping radially out of position. In order to counter counter-rotational precession of the rotor when it is supported externally by the auxiliary bearing system, and synchronous motion when it is supported internally, the auxiliary bearing elements (3, 4) are designed in such a way that they form on one side a contact surface (6) which provides external support for the rotor (2) and on the other side a contact surface (8) for internal support of the rotor. The two contact surfaces (6, 8) are brought, as the rotor moves increasingly out of position in the radial direction, successively into contact with the rotor, at least that bearing element which first acts on the rotor when the rotor moves out of position being fitted on a radially flexible mounting.

Patent DE-4304816-A1 (DE)
Title: Implement and method for stabilising and exploring soft subsoil
Inventor: GUDEHUS GERD PROF DR ING
IPC: E02D3/12
Filed: 1993-02-17
Abstract: The core of the invention is a displacement tip designed as a tapered slide at the end of a pipe driven into the ground. When the pipe is withdrawn, an annular gap opens up through which a granular paste or a dry powder penetrates into the cavity produced by the withdrawal. When the pipe is advanced again, the granulate is displaced and compacted together with the surrounding subsoil; axial and torsional vibrations assist this action without disturbing the sensitive environment. The implement is pressed in by a protective and guide pipe and is repeatedly withdrawn and advanced for injecting and compacting the granulate in various working positions. The implement is set up as a pump with drive and control members. The same implement also serves as a probe so that the type and quantity of the granulate can be adapted. A group of injection rods of this type can be fed in such a way that economically optimum, reliable and careful stabilising occurs. Rods or pipes for further improvement, reinforcement or test monitoring can subsequently be inserted into the column-shaped improved areas.

Filed: 1993-08-05
Abstract: According to the method described, the used aircraft deicing fluid is first subjected to conventional filtration for separating off undissolved substances and then to an ultrafiltration for separating off, in particular, polymeric thickeners. The ultrafiltration permeate is further treated with ionic exchangers and water is then separated off by distillation from the eluate obtained essentially comprising glycol and water and thus the glycol level is brought to the desired value. A new aircraft deicing composition can be prepared with the glycol/water solution thus obtained by adding the additional necessary components to the glycol/water solution.
