Title: Polycarbonate prepn. by interfacial polycondensation - with phosgenation of an aq. soln. of bisphenol in three stage reaction and feeding back aq. reaction phase to first step
Inventor: HERRIG WOLFGANG DIPL CHEM DR
IPC: G11B7/2534
Filed: 1992-12-10
Abstract: Prodn. of thermoplastic, aromatic, polycarbonates by interfacial polycondensation of phosgene, a bisphenol, chain stopper and opt. a chain branching agent, includes phosgenation of an aq. alkali soln. of the bisphenol in presence of a solvent (mixt.) in which the oligo-, aromatic polycarbonate is soluble, and which is not miscible with water. Reaction is at pH 4-8, in the presence of a polycondensation catalyst and in three, series-connected, reactors. The resulting aq. phase is mixed with further starting materials and fed back to the phosgenation reactor. An oil-in-water emulsion is formed directly and maintained in the three reactors for the entire reaction time. Pref., in a first step the aq. alkali soln. of the bisphenol is reacted with phosgene in presence of the recycled aq. reaction phase and the organic solvent and extra alkali. In a second step the intermediate prod. is further reacted with further caustic soda. In a third step the intermediate prod. is polycondensed into polycarbonate in the presence of the polycondensation catalyst. The alkali soln. contains 10-40 wt.% of bisphenol. The recycled aq. reaction phase contains 2.5-15 wt.% of bisphenol. The recycled aq. phase is cooled to such an extent that no further cooling is necessary to ensure that the b.pt. of the organic solvent is not exceeded in the three reactors. Alternatively, the b.pt. of the solvent is chosen so that no cooling is necessary. The first step lasts 10 seconds-30 minutes, the second step lasts 1-30 minutes and the third step lasts 2-30 minutes. ADVANTAGE - Good yields and reproducibility of MW for the polymers produced.

Title: Sewing machine, especially multi-needle double chain-stitch machine
IPC: D05B57/02
Filed: 1993-05-13
Abstract: In practice, in sewing machines, especially multi-needle double chain-stitch machines, it is necessary for the top threads to be cut off neatly at the end of the sewing operation, especially where large-surface sewing material is concerned, so that the appearance of the finished sewing material is not impaired by the protrusion of more or less long top-thread parts. In order to provide a top-thread cutting device which is of extremely simple and cost-effective design and, at the same time, works in a highly reliable way, it is proposed that each gripper be provided with a knife blade which is located at such a point on the gripper that, during the sewing operation, the top thread remains unaffected during the normal gripper movement and is severed only as a result of the deliberate controllable further pivoting of the gripper.
