Title: Magnetic recording material of chromium di:oxide type - having iron oxide coating obtd. by oxidn. of ferrous hydroxide pptd. under reducing conditions
Inventor: VAETH GUENTER
IPC: G11B5/712
Filed: 1977-11-07
Abstract: Magnetic recording material has a non-magnetic substrate with a firmly adhering magnetic coating of acicular ferromagnetic CrO2 finely dispersed in an organic polymeric binder and additives. Before incorporation in the binder, the CrO2 is suspended in an aq. soln. of the Fe(II) salt and a reducing agent, the Fe)II) ions are pptd. on the CrO2 as Fe(OH)2 by addn. of water-soluble hydroxide or carbonate and this Fe(OH)2 is then converted to an oxide deposit contg. Fe(III) by treatment with a gaseous or water-miscible oxidant. The oxide deposit pref. consists of goethite and/or lepidocrocite or magnetite. The Fe oxide deposit improves the stability and mechanical properties of the CrO2 under unfavourable climatic conditions.

Title: Oil furnace efficiency measuring system - measures level of blackening of filter belt continuously moving over extracting hole to ascertain soot content of flue gases
Inventor: KEHL ALBIN DR RER NAT
IPC: G01N15/06
Filed: 1978-10-19
Abstract: The continuous measuring arrangement is for the soot content in flue gases from oil furnaces. The flue gas is drawn through a continuously moving filter belt over an extracting hole. The level of blackening is evaluated by an electro-optical light reflectoring measuring unit installed close to the extracting hole. The result is shown in soot-count units. A reflectometer can be used for the light reflection measuring in which a photodiode is positioned coaxially in a transparent body serving as a light conductor. The emergent side is formed as a truncated cone facet. All the outer sides are smooth. The flue gas can be cooled below the dew point in a heat exchanger before passing through the filter band and then heated again from the released heat in the opposing stream.

Title: Appts. for scraping walls of felting chamber - in which scrapers consists of uprights moving on conveyor chains
Inventor: BARO ANTONIO TINTO
IPC: D01D5/18
Filed: 1979-05-21
Abstract: Appts. for scraping the walls of a felting chamber for prodn. of fibrous articles, esp. from fibres made of thermoplastic materials, such as glass, esp. glass fibre reinforced plastics, consists of a number of upright longitudinal pieces which are covered over the whole of their surface to be used with a scraper material which scrapes the wall surface. Each of these pieces is fastened to a two part drive chain by which they are driven, and which passes over the front and rear walls. The chain is driven by its own velocity-controllable motor. By means of this appts. the coating medium is applied to the near side of the scraper band for suitable cleaning of the parts of the chamber to be scraped. Crust formation on the chamber walls and subsequent detachment of lumps of crusted material into the felted body are avoided. Hence failure of prods. due to non-uniformity or local flaws is overcome.
