Title: Coating elements for components which contact the skin - e.g. door handles, has a surface layer contg. disinfectant
Inventor: RAMSPERGER UDO
IPC: A01N25/34
Filed: 1980-07-11
Abstract: Element for coating or enveloping components(or their parts)which come into frequent contact with human skin consists of a carrier element having at least one outer layer which contains skin-compatible antiseptic and-or mycotic agents which sterilise the surface of the active layer. The active layer is pref. made of porous material and contains additionally a compatible bactericide. This layer can be covered with a porous protective layer which allows the disinfectant components to leak onto the surface. Components coated in this way are also claimed. These elements are used to sterilise door handles, latches, door fittings, etc to prevent spread of germs. On contact with the device, some of the active ingredient is transferred to the skin, so the skin itself is sterilised. When the sterilising effect of the coating is exhausted it is simply removed and replaced.
Patent DE-3028065-A1 (DE)
Title: Dynamic converter for TV loudspeaker - has stray field reduction using magnet air gap filled with magnetic fluid
Inventor: THIELE KARL-HEINZ DIPL PHYS
IPC: H04R9/02
Filed: 1980-07-24
Abstract: The television sets are equipped with dynamic loudspeaker systems which suffer increasingly from the growing number of stray field sources. The fields can influence the tube deflection system and the shielding has to be increased to compensate. At present, the airgap of the magnetic body is filled with a magnetic fluid for damping and cooling purposes, but as yet is not intended to reduce stray fields. The magnetic fluid suggested for the latter use - as opposed to the air in the gap of known television loudspeakers - has a considerably lower magnetic resistance, by which, the qualities of the air gap region compare favourably with those of the magnet body. The field lines in the air gap region no longer extend into the region external to the magnet body, but are concentrated in the area of the magnetic fluid, leading to a considerable reduction of stray fields.

Title: Zinc alloy for hot dip galvanising steel - esp. silicon-contg. steel, contains antimony for uniform coating
Inventor: HAENSEL GUENTHER DIPL ING
IPC: C22C18/00
Filed: 1980-12-17
Abstract: A zinc alloy, for hot dip galvanising of steels, esp. silicon-contg. steels, has the compsn. (by wt.) up to 3% Pb, up to 0.03 (pref. 0.005-0.015)%Al, 1.0-10 (pref. 2-3)% Sb, balance Zn. Also claimed is the use of a zinc alloy of compsn. 0.005-0.015% Al, 2-3%Sb, balance Zn for hot dip galvanising of silicon-contg. steels, esp. silicon-killed steels. The Sb addn. to the alloy improves wetting of the steels and reduces the accelerate growth rate of Zn layers on silicon-contg. steels so that uniformly thick coatings are produced and flexibility in immersion times is increased. The Sb addn. also reduces the m.pt of the alloy so that hot dipping temps. of about 440 deg.C can be used. Steels contg. greater than 0.2%Si can be coated since the Al content of the Zn alloy is low. The presence of Sb in the Zn alloy increases the solubility of Pb so that higher Pb content Zn alloys can be used, with a resulting improvement in wettability.
