Title: Watchglass with diffraction grating
Inventor: YAMAZAKI YASUHIRO
IPC: G04B39/00
Filed: 1986-09-25
Abstract: As distinct from known watchglasses with a diffraction grating, which is formed by direct etching of the glass surface, in order to obtain the aesthetic effect of iridescence, the watchglass according to the invention with a diffraction grating is produced by first preparing a coating layer of a metal oxide, for example chromium oxide and indium oxide, or a metal, for example chromium, gold and nickel, and then engraving this coating layer line by line by a photolithographic process with a line pattern of lines and interspaces, forming the diffraction grating, so that the watchglass according to the invention does not show any reduction in mechanical strength, which is unavoidable if the diffraction grating is produced by direct etching of the glass surface.

Title: Hair care device with guided cutting knife
Inventor: HAYAT DJAHANGIR
IPC: B26B19/20
Filed: 1987-09-12
Abstract: A hair care device which is suitable both for combing and cutting is composed of a comb part with teeth, past which an integral cutting blade can be forcibly pulled and/or pushed. The hair collected by the teeth is gradually separated by means of this integral cutting blade, so that the amount of force which needs to be exerted can be kept within narrow limits. This makes handling of such a device much safer and easier. The integral cutting blade is approximately as long as the teeth and is fastened at its upper end to a button-like guiding part, which is displaceable in its turn in a guiding channel which is formed in the back of the comb. The actuating device is also fastened to this guiding part, with the advantageous effect that tilting of the entire cutting blade and/or the guiding part is prevented. <IMAGE>

Title: Process for desulphurisation and denitration of coal-fired furnaces and coking plants
Inventor: STOCKMANN HEINZ WERNER DIPL IN
IPC: C10L9/10
Filed: 1987-10-16
Abstract: Economical combustion of sulphur-containing hard coal (bituminous coal) and brown coal (lignite) and other fuels even in relatively small quantities is made possible, comparatively simply, by the fuel, while still bonded together underground, being admixed, with a high injection pressure, with the additives for desulphurisation and denitration of the flue gases. Provision is made for high-pressure water to be supplied, both by means of coal face infiltration (soaking) and by long-wall, deep, diagonal or remote infiltration (soaking) or by a combination thereof, the water being enriched with an appropriate amount of additives. The homogeneous distribution resulting therefrom, e.g., limewash suspension whose stoichiometric concentration depends on, e.g., the sulphur content of the coal, makes it possible to achieve and maintain a high degree of desulphurisation. <IMAGE>
