Patent DE-3409047-A1 (DE)
Inventor: FREMEREY JOHAN K
IPC: F16C32/04
Filed: 1984-03-13
Abstract: A magnetic bearing having contactless position stabilization of a supported body which includes a damping and aligning arrangement. This arrangement includes two spaced rotating annular permanent magnets which form a gap therebetween and which are attached to a rotor supported by the bearing. A stationary plate having good electrical conductivity and extending into the gap between the permanent magnets, is cut by their rotating magnetic flux. Mechanical disturbances of the rotor generate eddy-currents in the conductive plate which currents damp out these disturbances. A portion of the plate outside the gap is much thicker than the portion in the gap and provides a very low resistance path for the eddy-currents.

IPC: H02K29/00
Filed: 1985-01-15
Abstract: An energy converter having a magnetic-core intermediate store, characterised in that the magnetic-core intermediate store has allocated to it two external, parallel-connected magnetic circuits, which are of different dimensions, the first magnetic circuit, which is designated as a pulse-magnetising circuit, having a higher magnetic reluctance than the second, which is designated the operating circuit, the winding of the pulse-magnetising circuit having lower inductances and shorter time constants than the operating circuit, and in that the currents which are used for the purpose of changing the induction from positive to negative and vice versa in the pulse-magnetising circuit have (for the purpose of flux passing through the magnetic-core intermediate store in the opposite direction) a duration which is far less than the time which the operating circuit requires to complete the [lacuna] by the commutation of the flux direction in the magnetic core and to convert a part of the energy, which is buffer-stored in the magnetic-core store, into electrical or mechanical work. <IMAGE>
Patent DE-3503589-A1 (DE)
Title: Process for the preparation of vinylcyclopropanecarboxylic acid derivatives, intermediates to be employed in this process and process for the preparation of these intermediates
Inventor: SCHMIDT HANS-GEORG DIPL CHEM D
IPC: C07D309/30
Filed: 1985-02-02
Abstract: The present invention deals with a process for the preparation of cis/trans isomer mixtures of 2,2-dimethyl-3-( beta , beta -dichlorovinyl)cyclopropane-1-carboxylic acid esters, in which the cis isomer is formed in a far higher amount than the trans isomer. The process starts from starting compounds which have not been used hitherto for the preparation of this isomer mixture and some of which are also novel compounds. The process is characterised in that either a 4,4-dimethyl-5-halo-6-alkoxytetrahydropyrone or a 3,3-dimethyl-4-halo-5-oxopentanoic acid ester or a 2-alkoxy-6,6-dimethylbicyclo[3.1.0]-3-oxahexan-4-one is reacted with dichlorophosphonic acid esters in the presence of alcohol or of alkali metal alkoxides or of alkali metal hydrides or of lithium alkyls. The tetrahydropyrones which can be employed as starting materials are novel compounds for substance protection and a process for their preparation is claimed. This preparation process consists in reacting  beta , beta -dimethyl- gamma , delta -dihalo- delta -valerolactones with alcohols or alkali metal alkoxides. The reaction temperature in this process is between -10 DEG C and +50 DEG C.

Patent DE-3507835-A1 (DE)
Title: Device for damping oscillations
Inventor: KLUESENER-TRAUTMANN ROSWITHA
IPC: F16F9/10
Filed: 1985-03-06
Abstract: A safety damper, whose damping mass is arranged in the dashpot enclosed by a sleeve is used for damping oscillations of large machines and installations. The sleeve is in this case constructed and connected to the damper plunger such that the foot of the latter is also enclosed. The damping effect is thus ensured in all degrees of freedom of the system. As a result of a special construction of the foot of the damper plunger, allocation of angles or an oblique arrangement of the walls of the dashpot, the position and arrangement of the damping mass, which is suitably protected against contamination, are further improved. As a result of the special arrangement and of the special protection of the damping mass, it is possible to install such safety dampers in any position, that is to say both in oblique positions and in a horizontal position. In consequence, costly intermediate structures or other measures are superfluous. Furthermore, the safety damper according to the invention is also distinguished by the fact that it can be transported and installed easily and, as a result of its simple construction, can also be produced at favourable prices. <IMAGE>

Title: Device for processing object information
Inventor: SORIMACHI KANEHIRO
IPC: G06T1/00
Filed: 1985-03-08
Abstract: An object information processing device has an imaging unit for imaging light information from an object point, a light-transmitting unit for passing the light information from the object point to the imaging unit via a first and a second optical path and mask units, which are mounted respectively in the first and the second optical path of the light-transmitting unit and provided with respective predetermined mask patterns between which there is a negative/positive relationship. The light information from the object point is split up by means of the mask units into a multiplicity of items of range information from which patterns of range characteristics are formed. The patterns of range characteristics can be used for three-dimensional identification of an object with the aid of the processing device. Since the processing device has no mechanically moving parts, and the items of light information arriving respectively via the first and the second optical path are imaged next to one another on a photosensor, a high resolution is achieved, it being possible for mutually corresponding points of the object to be compared with one another without difficulty.
