Title: Pile fabric circular knitting machine - has rib needles associated with alternately effective vertical sinkers to guide yarns during loop formation
Inventor: NAGATA HIROKAZU
IPC: D04B9/12
Filed: 1977-02-02
Abstract: Pile fabric circular knitting machine has vertically movable sinkers carried by rings which depend from a support plate which also carries the rib disc with its associated rib needles. Sinkers move alternately into contact with the rib needles which are slidably mounted in radial grooves of the disc. Arrangement is such that the yarn engaged by a rib needle can be guided by the neighbouring sinkers so as to remain at a predetermined position when the rib needle is displaced radially outwardly relative to the rib disc in order to engage a further yarn needed for interlocking or when an associated cylinder needle moves upwardly to release a pile loop in its uncut state or with a cutting disc rotatable about a horizontal axis to release a cut pile loop. Since faults in knitting are avoided at each of the knitting stations fabrics with delicate patterns, uniformly long pile and high quality of finish can be produced.

Title: Chromating of aluminium substrates for magnetic storage plates - via acid soln. sprayed onto the plates to ensure that adherent chromate passivation with good corrosion resistance is obtd.
Inventor: FALK ROLAND DIPL CHEM DR
IPC: G11B5/84
Filed: 1978-10-02
Abstract: The substrates are kept in a horizontal position while they are conveyed through a spraying chamber, in which the substrates rest via changing point contact on a support. Vertical streams of an acid soln. are sprayed for a specified time downwards and upwards from nozzles onto the substrates to form the chromate. The substrates are then washed with water and dried via warm air. During the spraying of the acid soln., the nozzles are pref. subjected to swivel or yawing motions. The finely machined surface of the Al is passivated by a chromate layer prior to the deposition of a magnetisable layer, to obtain good corrosion resistance, and good adhesion of the magnetisable layer. The process improves the quality of the passivation.
