Inventor: GIERTZ HANS JOSEF
IPC: C10B27/06
Filed: 1993-07-12
Abstract: A process is disclosed for regulating the gas pressure in the retort of a coke oven.

Title: Nucleotide sequence encoding carbamoyl phosphate synthetase ii
Inventor: STEWART THOMAS STANLEY
IPC: C12R1/19
Filed: 1993-12-02
Abstract: The present invention provides a nucleotide sequence encoding carbamoyl phosphate synthetase II of plasmodium falciparum. Carbarnoyl phosphate synthetase II catalyses the first committed and rate-limiting step in the de novo pyrimidine biosynthetic pathway. P. falciparum relies exclusively on pyrimidine synthesis de novo because of its inability to salvage pyrimidine. Mature human red blood cells, however, have no recognised requirement for pyrimidine nucleotide. Accordingly, this enzyme represents a prime chemotherapeutic locus. The present invention relates to the use of the sequence encoding carbamoyl phosphate synthetase II in the recombinant production of carbamoyl phosphate synthetase II and to antisense molecules, ribozymes and other gene inactivation agents designed from this sequence.

Title: Process for the production of nitroaromatic compounds
Inventor: KLINGLER UWE
IPC: C07C201/08
Filed: 1995-08-07
Abstract: Nitroaromatic compounds are produced by continuously reacting an aromatic compound with nitrating acid. The reaction mixture is separated into an organic phase from which the desired nitroaromatic compound is recovered and an acid phase. The acid phase is subjected to flash evaporation to remove at least 5% by weight of the water present therein. The vapors generated during the flash evaporation are introduced into a jet spray of coolant to produce a condensate made up coolant, condensed vapors and suspended organic compounds. A portion of the condensate is subjected to phase separation to remove water and organic compounds present therein. The water and organic compounds may be reused. The process of the present invention is particularly advantageous in that deposits which block pipelines and interfere with heat transfer are not generated.

Title: Low cost active power line conditioner
Inventor: BRENNEN MICHAEL B
IPC: G05F1/70
Filed: 1994-03-01
Abstract: A novel active power line conditioner (34) is disclosed. The apparatus includes a parallel inverter (30), with a de-link, coupled to an output line. The parallel inverter (30) is controlled by a parallel inverter controller (40) which forces the parallel inverter (30) to act as a variable capacitor or inductor. The parallel inverter controller (40) identifies and feeds-forward a desired phase shift value between an active power line conditioner voltage input signal and an active power line conditioner voltage input signal. Utilization of the desired phase shift value results in voltage control of the de-link of the parallel inverter (30). The parallel inverter controller (40) also produces a tuning capacitance current reference signal which reduces voltage magnitude errors of the output voltage.
