Title: Industrial dust disposal esp. for synthetic resin by combustion -  in blast furnace after premixing dust with separate airstream, avoiding pollution
Inventor: KALLSEN JOACHIM
IPC: A62D3/38
Filed: 1990-08-25
Abstract: Disposal process for industrial dust, esp. contg. all types of synthetic resin, e.g. furan, urethane and phenolic resins, is carried out in a blast furnace with a definite oxidn. zone, in which air for combustion is injected near the bottom.  The novel features are that the dust is mixed intimately with a separate air stream in a given mixing ratio and the resultant dust-air mixt. is injected into the oxidn. zone with a relative speed with the air for combustion. USE/ADVANTAGE - The process is compatible with the environment. The distribution of the dust particles in the air stream is as uniform as possible, ensuring rapid and complete combustion (at over 1600deg.C), even of gases formed, e.g. CO and any unburnt cracking prods., e.g. CH4.

Title: Spinning frame - has separate drives for traverse winding motion and lifter mechanism
Inventor: BROCKMANNS KARL-JOSEF DR ING
IPC: D01H1/36
Filed: 1991-01-29
Abstract: Yarn is wound in a relative position. It is arranged for the yarn guide traverse to be separately driven from the mechanism for the lift. The appts. is also claimed. Pref., on a ring frame, the spindle is driven separately by the motor. The base is mounted on a bracket which is brought from the nut on the threaded shaft. This is supported in the housing.

Title: Recycling lye extracted from cellulose@ mfg. plant - has recycling system incorporated to separate valuable material from lye for re-use in plant
Inventor: FAEGERLIND OLOF
IPC: C07C31/04
Filed: 1991-05-24
Abstract: A process to recycle the lye extracted from a cellulose mfg. plant. There are several stages of recycling and distn. of the volatile fluid, using equipment which is integrated in the plant. ADVANTAGE - There is a saving of energy for the process as the products are re-usable. The cellulose is made from wood chippings, having an initial process with alcohol, methanol or similar fluid with a low b.pt., heated with water for a specified time. Then follows a caustic soda treatment, on similar lines, and as the cellulose prod. is washed, the weak lye is extracted and passed to the expansion chambers to reduce the temp. and pressure. A pre-heater takes treated lye back to the condenser with steam to concentrate the fluid to a high viscosity, with a percentage of lignin. This extract is then burned in the process boilers. Concd. lye is also re-used. Vapour from the unit is combined with that extracted from the expansion chambers and passed into the vaporiser, which again separate the volatile material with a lower b.pt. Condensate is also extracted at this stage. Clean water, steam and vapour condensate are then passed along the system. The vaporisers have separate heating arrangement, with either plates or tubes in each stage. A regenerative system and a columnar unit allow further sepn. and distn. when gas is cooled and extracted to be burned in the boilers. Pure methanol for re-use is also produced. Condensate and water used in the washing process of the cellulose is extracted at the points indicated

The prepn. of captopril from L-proline via (I) gives yields of more than 50% (based on L-proline, compared to e.g. a previous process using 3-(ethanoylthio)-2-(methyl)-propionic acid as the acylating agent, which gave yields of only 10% based on L-proline. Other previous processes, were little better, giving yields of 30% or 34-35%. The prepn. via (I) is simple. (I) itself is produced by a simple and economical process.
