Abstract: PCT No. PCT/EP85/00544 Sec. 371 Date Jun. 24, 1986 Sec. 102(e) Date Jun. 24, 1986 PCT Filed Oct. 17, 1985 PCT Pub. No. WO86/02583 PCT Pub. Date May 9, 1986.A method and an apparatus for the detection of slag co-flowing within a stream of molten steel being poured from metallurgical vessel, more particularly during continuous casting, makes it possible to detect even a small quantity of slag in the emerging flow of molten metal without requiring the removal of the shielding for the pouring stream, or without interfering with the pouring, by measuring changes in the electrical conductivity of the pouring system by means of electromagnetic fields. To this end, one or more transmitter coils and receiver coils are mounted fixedly around the pouring stream. The transmitter coils are fed with a current containing several frequencies, and the magnitude and phase position of the voltage induced in the receiver coils are evaluated frequency-selectively so as to increase the sensitivity, the measuring transducer being operated in a bridge circuit. The change in electrical conductivity of the pouring stream and, hence, the quantity of slag, are determined from the magnitude and phase position of the voltage induced in the measuring coils. Temperature-dependent errors are largely suppressed.

Abstract: A hybrid polypeptide composed of an identification peptide and a desired functional protein are produced by recombinant DNA techniques. A DNA expression vector is constructed that includes segments of DNA coding for the identification peptide and the desired functional protein. The identification peptide consists of a highly antigenic N-terminal portion and a C-terminal linking portion that connects the identification peptide to the N-terminal of the functional protein. The linking portion of the identification peptide is cleavable at a specific amino acid residue adjacent the functional protein by use of a sequence specific proteolytic enzyme or chemical proteolytic agent. The hybrid polypeptide expressed by the host cells transformed by the cloning vector is removed therefrom and purified by affinity chromatography techniques by use of an immobilized ligand specific to the antigenic portion of the identification peptide. The protein is then cleaved from the isolated hybrid polypeptide with an appropriate proteolic enzyme or chemical agent, thereby releasing the mature functional protein in highly purified, highly active state.

Abstract: A high-density fermentation process for high yield production of a protein having swine growth hormone activity by transformant E. coli strains is described. The process employs transformant stains of E. coli containing a gene coding for a protein having swine growth hormone activity under the control of a bacteriophage lambda promoter-operator and a gene coding for the λc1857 temperature-sensitive repressor protein. In the initial growth period, the level of dissolved oxygen in the fermentation medium is maintained at about 20 % to 60 % of saturation and the temperature of the medium is maintained at a temperature at which the λ c1857 repressor protein is active. Production of the desired protein is then induced by raising the temperature of the medium to at least about 42°C. The temperature is then reduced to about 38°C to 41°C to optimize cell growth for the remainder of the induction period, during which the level of dissolved oxygen in the medium is maintained at about 10% to 40 % saturation, and the protein having swine growth hormone activity thus produced is recovered from the transformant cells.

Abstract: The watch comprises a conventional timepiece movement driving the hours-hands, the minutes-hands and the seconds-hands, to which is added a chronograph module the frame of which, having the shape of a bell, covers the movement of the timepiece. The chronograph is autonomous, i.e. its indicators are not driven by the basis movement but by electric motors situated around the central movement, fed by a battery and piloted by a quartz oscillator, the frequency divisions being effected by an integrated circuit. The printed circuit associated with this whole comprises an annular plate surrounding the timepiece movement. An intermediary plate ensures the connection between the timepiece movement and the chronograph module. The transformation of a conventional timepiece movement into a chronograph watch is thus very easy, the chronograph module being able to be applied to very different timepiece movements, only the intermediary plate having to be different.
