Abstract: Blends of glycerides and/or fatty acids comprising 20 to 65 wt % C16:1 fatty acid, balance other fatty acids with 12 to 24 C-atoms and having a C16:1 to C16:0 fatty acid ratio of more than 2.0 and an C16:1 to C18:1 fatty acid ratio of more than 1.2 perform well in food applications. These blends of glycerides can be made by a process involving a partial enzymic hydrolysis of materials derived from fish oil using an enzyme with specificity for C16:1, removal of the fatty acids and a fractionation of the acids.

Abstract: The invention relates to a synthetic quartz glass preform which is produced according to the flame hydrolysis technique with subsequent cooling and is suitable for the application of high-energy DUV radiation in the wave length range under 250 nm. Said preform has a core area which contains ≧1150 ppm OH, a strain double refraction of ≦5 nm/cm and a resistance to high-energy DUV radiation as a result of a transmission reduction of &Dgr; T ≦0.1 %/cm thickness. The quartz glass has been exposed to the following radiation: wavelength &lgr;1=248 nm, laser shot frequency ≧300 Hz, laser shot value ≧109 and rumination ≦10 mJ/cm2, and wavelength &lgr;2=193 nm, laser shot frequency ≧300 Hz, laser shot value ≧109 and rumination ≦5 mJ/cm2. A device for producing said preform comprises a horizontally positioned muffle with two different-sized openings facing each other. The larger of said openings is for removing the preform, the smaller opening being for introducing a burner.

Abstract: In a method for producing a streak-free quartz glass sheet with a highly homogeneous degree of refraction, a quartz glass rod is lowered into a melting pot parallel to a longitudinal axis of the quartz glass rod. A cross-section of the melting pot is larger than a cross-section of the quartz glass rod and determines a contour of the quartz glass sheet. The quartz glass rod is heated in the melting pot to a flow temperature whereupon the quartz glass rod is lowered until the quartz glass rod melts and a height of the quartz glass flowing in the melting pot reaches a desired quartz glass sheet thickness. The melting pot and the quartz glass rod move relative to each other in a direction which is perpendicular to the longitudinal axis of the quartz glass rod during the melting process. Preferably, the movement involves a rotational and a transverse movement.
