Title: Magnetic contactless bearing for high speed rotors - is combined with mechanical thrust bearings and regulator reducing shock loads
Inventor: BECKER WILLI ING GRAD DR
IPC: F16C39/06
Filed: 1978-06-10
Abstract: The rotor magnetic radial bearing ensures contactless support of the rotor. A mechanical axial bearing holds the rotor in the vicinity of the equilibrium position. The system is used for example for turbomolecular pumps in high vacuum technology. The bearing system damps critical shock movements without damage to the rotor. The nonrotating part of the thrust bearing has a measuring sensor generating a signal proportional to the axial thrust force exerted by the rotating part on the nonrotating contact face of the thrust bearing. The system has a regulator which limits the axial spacing of the rotor from the unstable equilibrium position. The regulator ensures that the contact force is held below a specified value. In case of excessively high contact force the distance from unstable equilibrium position is reduced automatically by axial displacement of bearing elements.

Title: Ferromagnetic abrasive shot for treating printed circuit boards - in magnetic field, consists of aluminium and silicon oxide, carbide, nitride, and phosphide in ferrous alloy
Inventor: CHOMITSCH NIKOLAJ S
IPC: C22C32/00
Filed: 1978-07-03
Abstract: The abrasive consists of a ferromagnetic alloy contg. by wt. 75-97% Fe, 0.2-16% Al, 0.2-18% Si, 0.005-1.5% P, 0.005-4% C, 0.05-3% O2, and 0.01-0.5% N2; and included in the above is 0.01-5% of the oxides, carbides, nitrides and phosphides of Al and Si as abrasives. The abrasive is pref. made by melting an alloy of Fe-Al-Si-P and heating it to 50-200 degrees C. above its initial crystallisation temp.; carbon is added to the melt, which is then converted into shot of below 1.5mm size by the gas stream. The gas contains by wt. 99.999-75% N2 and 0.001-25 wt.% O2, and is used at 2-20 atmos. and a speed of 150-500 metres/second to make the shot, which is cooled to room temp. The abrasive polishes the surface of components and produces very low surface roughness if required. Compared with known abrasives used in magnetic grinding, the invention uses only a small amt. of diamagnetic particles, and the shot has high hardness and strength.

Title: Synchronisation system for data transmission - pre-synchronises data to inverted or non-inverted internal clock prior to external synchronisation
Inventor: POLATZEK HANS-DIETER ING GRAD
IPC: H04L7/00
Filed: 1978-08-19
Abstract: The sync. system compares the phase of external clock pulses with that of internal clock pulses derived from the data signal. Phase differences less that 90 deg. cause the data signal to be presynchronises by the inverted internal clock pulses whilst phase difference greater than 90 deg. cause it to be presynchronised by the non-inverted internal clock pulses. The result of this presynchronisation is synchronised to the external clock pulses when the phase difference changes from 'not equal to 90 deg.' to 'equal to 90 deg.'.

Title: Coiler laying fibre band into container - which maintains constant feed without drawing or compacting fibre by centrifugal action
Inventor: SCHMID REINHOLD
IPC: B65H54/80
Filed: 1979-06-13
Abstract: A length compensator for the band of fibres delivered, is provided in a coiler for layering down the band in loops resembling cycloids, into a container, above which the coiler rotates with constant angular velocity. Pref. the compensator consists of a dishlike rotor, the concave side of which is inclined obliquely outwards. The band enters the dish ffom above radially,and leaves below radially or with a radial component. The dish has on its concave side, a bottom, a sub and a rim. Rim, bottom and hub blend into each other over radii, and at least between bottom and rim there is a flute. The outer surface of the rim forms part of a friction drive, which includes a bell with a friction surface positioned concentrically to the axis of the coiler, and a wheel in contact with the friction surfaces of the rotor and the bell. The axis of the rotor is inclined to that of the coiler and the rotor has a cover fixed by its shaft to the coiler. There are perforations in the flute at the base of the rim and at the point where the fibre leaves the rotor, a compressed air line blows from outside against the perforations. Above the coiler a feed funnel is fixed and has a collecting chamber for compressed air, sealed against the coiler and feeding both the air line mentioned, and a line blowing against perforations in the coiler wall at the point where the band of fibre leaves. Used to lay down a band of fibre more uniformly into a container such as a can, without the band being drawn or compacted. This has the further advantage that the band can be spun into yarn without the normal periodic variations. When woven, this yarn does not give moire effects.

Title: Focusing system for colour CRT - uses ring shaped permanent magnet spaced from lens formed by anode and outer electrode
Inventor: SROWIG REINHARD ING GRAD
IPC: H01J29/70
Filed: 1979-08-25
Abstract: The in-line colour CRT has an electron beam generator with a cathode (K) enclosed by a grid electrode (G1) followed by two further grid electrodes (G2,G3) and an anode (A). For focusing the two outer beams (31) so as to direct them to a common point on the colour selector mask behind the screen, the anode and the outer electrode (G3) are used as a lens.

Patent DE-2940129-A1 (DE)
Inventor: SATOH MITSUHIRO
IPC: F16H63/20
Filed: 1979-10-03
Abstract: A gear shift mechanism fore change-speed gearbox is operable by a gear lever 8, and includes two juxtaposed shift forks 6A, 6B and a mechanism for inhibiting simultaneous actuation of the shift forks. The gear lever is selectively engaged with one of the recesses 6a, 6b in either shift fork in order to effect gear changing. These recesses are mutually opposed, when in the neutral position of the mechanism, and have a common zone 10 which bridges the recesses in the region of the bottoms of the recesses and which is so shaped as to prevent rocking of the lever, when the latter is engaged therewith, to select one of the recesses 6a, 6b. A spring 12 urges the gear lever into engagement with the common zone 10 when the shift forks are in the neutral position. In order to shift the gear lever into engagement with only one of the shift fork recesses 6a or 6b, it is first necessary to lift the gear lever from the common zone 10 against the action of the spring 12. Hence, when the shift mechanism is in neutral and the gear lever is engaged with the common zone, accidental or unintentional actuation of the lever is inhibited. <IMAGE>
