Within the nozzle head is located a rotatable element defining a through-hole. The through-hole is shaped in such a way that the opening at one end is of relatively small cross-section and at the opposite end of a relatively large cross-section. The rotatable element is sealingly arranged in the nozzle head and has an external groove. The rotatable element can be positioned in at least a first rotational position to facilitate flow of spraying liquid from the conduit, to the nozzle inlet, and through the through-hole in the rotatable element, to the nozzle outlet for forming spray jets at the outlet. A second rotational position allows liquid to be flushed through the conduit by flow of the spraying liquid from the inlet, through the groove, and exiting the nozzle through a flush hole. A third rotational position allows the through-hole to be flushed by the flow of spraying liquid from the nozzle inlet through the through-hole in a second direction opposite to the first direction.

Abstract: An improved process for the preparation of a valuable drug.  The present invention relates to an improved process for the preparation of Fluoxetine hydrochloride, used as an antidepressant, i.e. N-methyl-3-(p-trifluoromethylphenoxy)-3-phenyl-propylamine hydrochloride, by catalytic hydrogenation of 2-benzoyl-N-benzyl-N-methylethylamine base with the aid of Pt/C or Pd-Pt/C at a hydrogen pressure of 5 bar at 50°C, with ethyl acetate as a solvent, whereby 1-phenyl-3-(N-methylamino)-propane-1-o1 is produced.  This compound is etherified selectively by using 1-chloro-4-trifluoromethyl-benzene in N-methyl-pyrrolidone at 80°C in the presence of potassium iodide and by using potassium-t-butoxide as the base, whereby N-methyl-3-(p-trifluoromethylphenoxy)-3-phenyl-propylamine,, i.e.          Fluoxetine base, is formed, which is converted in a known manner into Fluoxetine hydrochloride, i.e. N-methyl-3-(p-trifluoro methylphenoxy)-3-phenyl-propylamine hydrochloride.

Title: Phase comparison relaying system with single channel communications link
Inventor: CHYI SUN SHAN
IPC: H02H7/26
Filed: 1990-03-13
Granted: 1995-08-01
Abstract: The square wave phase comparison signals generated for  each  phase  of  a  power  distribution  system  by  phase comparison  relays  at each end of a protected  three phase transmission line segment are combined to generate a single, multi-level   signal   with   discrete   values   for   each instantaneous  combination  of  square  wave  signals.    The single, multi-level  signal  is  used  to modulate a carrier signal which is transmitted over a single channel of a two-way  communications  link  to  the  other  terminal  where the carrier signal is demodulated to reproduce the multi-level signal.   The reproduced multi-level signal is then decoded to generate remote square wave signals which are compared with the phase of locally generated square wave signals to generate trip signals for circuit breakers at the respective terminals.     Square  waves   representative   of  priority functions, such as direct transfer trips, can be integrated into the single, multi-level signal transmitted to the other terminal.
