Abstract: Dehydration of 11a-chloro-5-hydroxytetracycline-6,12-hemiketal (II) to 11a-chloro-metacycline (I) is effected using a dehydrating reagent (DHR) consisting of a soln. of sulphuric acid in formic acid. Amt. of DHR used is pref. such that the mixt. at the end of the reaction contains 0-3 (pref. 1-2) mol. water per mol. of (II) used. DHR is pref. prepd. starting from aq. HCOOH by reducing or removing the water content by reaction with an acid chloride or anhydride, esp. sulphur trioxide or fuming sulphuric acid. USE/ADVANTAGE - (I) is an intermediate for the tetracycline antibiotic deoxycycline. (I) is obtd. in high quality and yield without using (dangerous) anhydrous HF or (unstable) anhydrous HCOOH. Cheap, stable, commercially available 85% HCOOH can be used to prepare DHR. In an example, 150 ml HCOOH (165 g/l water; i.e. 1.375 mol. water) was treated dropwise under stirring and cooling to -5 to +5 deg.C with 97.2 ml fuming sulphuric acid contg. 65% SO3 (1.576 mol). The obtd. DHR was treated at -10 to -5 deg.C with 132 g (0.2 mol) (II). HCl (79.9%; water content 6.5%, i.e. 0.477 mol). The mixt. was stirred for 5 hrs., with temp. rising to 23 deg.C, then treated over 15 mins. at 5-10 deg.C with 110 ml isopropanol and 50 ml acetone, stirred for 10 mins., filtered and washed with 100 ml acetone. The filtrate was treated with a soln. of 29p p-toluenesulphonic acid in 120 ml iPrOH, seeded with 0.2 g (I) toluenesulphonate, stirred for 10 mins. and left to stand overnight. The crystals were filtered off washed with acetone and dried to give 29.1g (89.7%) of (I) p-toluenesulphonate.

Title: Line protection circuit breaker
Inventor: BUEHRER WERNER
IPC: H01H71/52
Filed: 1993-03-22
Abstract: The line protection circuit breaker contains a magnetic short-circuit current release and a thermal overcurrent release with a bimetallic strip (10). In the case of this line protection circuit breaker, the line current is carried in a current path which, in addition to two contacts (44, 48) which move relative to one another and a section of the bimetallic strip (10), also has an electromagnetic coil (22) and a section of a yoke, which contains ferromagnetic material, of the short-circuit current release. The magnetic field which is produced by the coil (22) in the event of a short-circuit current is used to attract an armature (24) of the short-circuit current release and for magnetic blowing of a switching arc which forms while the contacts (44, 48) are opening. That yoke section which carries the current is formed by a non-ferromagnetic metallic material whose mechanical strength is comparable with that of the ferromagnetic material of the yoke, but which has an electrical conductivity which is a plurality of times greater than this material. The line protection circuit breaker is distinguished by a very high rated current capacity, while being of compact construction. <IMAGE>

Title: Engine for spacecraft (space vehicles)
Inventor: STEENBORG MANFRED
IPC: H05H1/34
Filed: 1993-06-30
Abstract: A thermal arc-jet engine which serves, in particular, the purpose of attitude correction and orbital (orbit) correction of spacecraft consists of a housing constructed as an anode, at the same time an expansion nozzle, and a rod-shaped, electrically insulated cathode which is held centrally therein. The cathode is arranged in a combustion chamber into which gaseous ammonia is injected as the working gas. The tip of the cathode is spaced from the restricted cross-section of the nozzle throat by a small air gap. When there is a flow of gas, an arc is struck between the anode and cathode and the working gases absorb additional thermal energy from it. The entire arrangement is designed such that the device for generating the working gases, the guide device for the working gases generated in it, and the actual arc-jet engine are arranged in series on a common axis. For this purpose, the cathode is connected to the device for applying electric power via a flexible lead element which is guided laterally out of the housing. Connected upstream of the combustion chamber is a device in which the ammonia is dissociated in a catalytic and/or thermal way into the components of hydrogen and nitrogen.
