Title: Sealing device for the drive a haft of a high pressure fluid pump
Inventor: BONHOMME NICOLAAS
IPC: F04D29/10
Filed: 1982-05-21
Granted: 1988-07-16
Abstract: The high pressure pump for pumping fluid has a series of shaft seals (33-35) of which at least one (33) is of the hydrostatic type with a controlled leak.  A mechanical seal (45) is mounted upstream of this hydrostatic seal in a chamber (46) which is supplied with high pressure fluid.  The flow of fluid from one side (46a) to the other side (46b) of the chamber (46) is controlled by a valve (48) which can also isolate one chamber from the other.  A non-return valve (49) allows fluid to flow from one chamber to the other when the pressure in the first chamber exceeds that of the second.

Title: Method for promoting disulfide bond formation in recombinant proteins
Inventor: KOTHS KIRSTON EDWARD
IPC: C07K14/52
Filed: 1985-11-27
Granted: 1994-04-22
Abstract: Reduced cysteine-containing proteins consisting of recombinant IFN-β, IL-2 muteins thereof may be oxidized selectively so that the recombinant proteins have essentially the same disulfide bridging and biological activity as their native counterparts. The oxidized product is substantially free of unwanted side products and contains a minimal amount of intermolecular oligomers. The oxidation takes place in an aqueous medium containing a solubilizing agent at a pH of about 5.5 to 9, preferably at a pH of about 7. The reaction is initiated by addition of at least an effective amount of an oxidation promoter containing a Cu<sup>+2</sup> cation such as CuCI<sub>2</sub> or o-phenanthroline/Cu<sup>+2</sup> complex in the presence of air.

Title: Clamp circuit
Inventor: KIMURA YUICHIROU
IPC: H04N5/18
Filed: 1986-03-21
Granted: 1990-04-21
Abstract: The clamp circuit has a capacitor provided between an amplifier whose output impedance is relatively high and a cathode of a cathode ray tube.  A transistor is also provided having an emitter-collector path connected in parallel with the capacitor and a base electrode which is connected to a DC voltage source through a switch which is turned on during a horizontal retrace period and off during a horizontal scan period.  A DC restoring operation is achieved by causing almost all of the discharge current of the capacitor to flow through the emiter-collector path, resulting in less discharge current flow through the output impedance of the amplifier.

Abstract: The circuit is for improving  the  definition  ratio  of  the picture without increasing the frequency  bandwidth  in  the  NTSC image processing system. The  circuit  also  prevents  the  second harmonic involving into the configuration compensation element  so that the level conversion time of the image signal is reduced  and the roll- off quantity is controlled. The circuit comprises a first pass delaying the input brightness  signal  for  certain  time,  a converter  reforming  the  wave  by  differentiating   the   input brightness signal and taking its  absolute  value,  a  quantitised means emphasising the signal with low signal  difference,  but  by passing it with the high signal difference  after  differentiating again,   a   gain   controller   controlling   the   configuration compensating quantity, and an adder adding compensation signal  to the original one.

Title: Process for manufacturing hydrazine
Inventor: SHIN KWI-NAM
IPC: C01B21/16
Filed: 1990-10-18
Granted: 1993-05-08
Abstract: The hydrazine is produced by (a) reacting an ammonium chloride with a ketone of R1R2-C=O [R1=R2=C1-4 alkyl  using a barium peroxide as an oxidant to obtain a ketazine R1R2-C=N-N=C-R1R2 [R1=R2=C1-4 alkyl , (b) double-decomposing the obtd. barium chloride with a sodium hydroxide to obtain a barium hydroxide, and then oxidizing the barium hydroxide at 400-500 deg.C to continuously recycle the barium peroxide, and (c) acid-hydrolyzing the obtd. ketazine.

Patent KR-0145738-B1 (KR)
Title: Novel bacteriocin compositions for use as enhanced broad range bactericides nd method of preventing and treating infelction
Inventor: BLACKBURN PETER
IPC: A01N63/50
Filed: 1990-02-27
Granted: 1998-08-01
Abstract: Broad range bacteriocin compositions are provided. The compositions can be dissolved or suspended in a suitable solvent or matrix and are more active towards a broader range of bacteria than are any of the component parts. The dissolved or suspended compositions constitute enhanced broad range bactericides. The compositions include lysostaphin and a lanthionine containing peptide bacteriocin; lysostaphin, a lanthionine containing peptide bacteriocin and a chelating agent; and lysostaphin, a lanthionine containing peptide, a chelating agent and a surfactant. Each component is present in the enhanced broad range bactericide in sufficient amount such that the bactericide is more effective against staphylococci than is lysostaphin alone and is more effective at treating and preventing a broad range of microbial infections. Methods of treating bacterial infections using said compositions and bactericides are provided.
