摘要:
A frictional damper for spinner-type washing machines comprises a housing and a tappet, which is coaxially displaceable within the latter and the inner end of which is provided with a damping piston. The damping piston is disposed on a piston-bearing section of the tappet to be displaceable between biased compression springs bearing against stops, and provided with a friction lining elastically pressed against the inside wall of the housing.

The invention relates to a coupling device (19) for coupling a frictional damper with a middle longitudinal axis (21), which is coupled to an oscillatory washing unit with a drum axis, to a machine frame of a washing machine with a spin gear. The coupling device has a first bending axis, which runs vertically to the central longitudinal axis (21) and parallel to the drum axis, a second bending axis (33) which runs vertically to the central longitudinal axis (21) and to the first bending axis and intersects both at one point, a first connecting element for connecting the coupling device (19) to the frictional damper, a second connecting element for connecting the coupling device (19) to the machine frame and a spring element (24) that is located between the first connecting element and the second connecting element and is connected to both, the flexural strength of the coupling device (19) about the second bending axis (33) being greater than the flexural strength about the first bending axis.

A method of inhibiting lipoxygenase in a patient, for the prophylaxis and/or treatment of ischaemias and disorders in cardiac rhythm and of rheumatic, allergic and asthmatic diseases, oedemas, pulmonary embolisms, pulmonary hypertension, oxygen intoxications and ulcerations which comprises administering to such patient an effective amount of nafazatrom.
摘要:
A process for the manufacture of magnetic recording media by dispersing a mixture of particulate anisotropic magnetic material and additives in a solution of a polymeric binder in an organic solvent, compressing and then releasing the pressure on the dispersion, thereafter applying a layer of the dispersion to a non-magnetizable base, orienting the anisotropic magnetic material by means of a magnetic field, and drying the coating.
摘要:
The invention relates to an improved apparatus for the manufacture of magnetic discs carrying very thin magnetic layers, by applying a fluid dispersion of magnetic materials in a binder mixture to rigid base discs by the spin-coating process. Above the side of the base disc which is to be provided with the magnetic layer, there are arranged means which produce an aerodynamic boundary layer above the discs during rotation of the latter. This avoids the formation of surface irregularities and of coating streaks during production of the layer by spin-coating.
