Title: Method and apparatus for controlling hydraulic systems of construction equipment
Inventor: MASUZAWA JUN
IPC: F04B49/06
Filed: 1994-10-04
Granted: 2000-03-21
Abstract: A controller regulates a hydraulic pump for hydraulic equipment to allow long-term use of environmentally safe hydraulic fluids. This is accomplished by limiting the hydraulic pump power output to a level established to prevent the operating temperature from exceeding a specified level. A manual mode for switching between power curves permits alternate use of hydraulic fluids having different maximum operating temperatures.      An automatic mode detects the type of hydraulic fluid and automatically selects and applies a suitable power mode curve to limit the maximum operating temperature to a value suitable for the detected type of fluid.

Abstract: The present invention is concerned with a series of novel monoclonal antibodies directed against CD22, a B lineage-restricted member of the Ig-superfamily which serves as an adhesion receptor expressed by matu re B lymphocytes and is believed to function in the regulation of B cell activation. The monoclonal antibodies (mAb) specifically block red blood cell and leukocyte adhesion (80-100 %) to COS cells transfected with CD22 cDNA and also identify a region of CD22 distinct from those defined by previously described CD22 mAb. The invention also encompasses therapeutic compositions including therapeuticall y effective amounts of a polypeptide comprising the CD22 ligand or portion thereof or of a polypeptide comprising the first two amino - terminal Ig-like domains of CD22, or the ligand binding portion thereof. The antibodies and polypeptides of the invention find use in therapeutic methods for treatment of humans to retard or block CD22 adhesive function, particularly in autoimmune disease.

Abstract: In a load loss standard for calibrating a power measurement system, a pair of reference voltage signals are generated, one in-phase and the other in quadrature with a test voltage ac source. A transconducting and summing amplifier generates an output current corresponding to the vector sum of these reference signals. By varying the magnitude of each of the reference signals independently of each other it becomes possible to vary the phase of the output current relative to the source, while keeping the magnitude of such current constant.

Title: Method for reproducing in vitro the proteolytic activity of the ns3 protease of hepatitis c virus (hcv)
Inventor: DE FRANCESCO RAFFAELE

Granted: 1999-07-06
Abstract: This is a method for reproducing in vitro the serine protease activity associated with the HCV NS3 protein, that comprises the use both of sequences contained in NS3 and sequences contained in NS4A. This method takes advantage of the ability of the HCV NS4A protein, or sequences contained therein, to act as a cofactor of the serine protease activity or more generally of the enzymatic activities associated with NS3. Optimal serine protease activity is obtained when NS4A is present in a molar ratio of at least 1:1 with NS3, NS3 and NS4A can also be incorporated in the reaction mixture as NS3-NS4A precursor, at this precursor will generate, by means of an autoproteolytic event, equimolar amounts of NS3 and NS4A. It is also possible to mutate the cleavage site between NS3 and NS4A in a precursor, so that NS4A remains covalently bonded to NS3. The sequences that do not influence the proteolytic activity of NS3 can subsequently be removed from said non-proteolyzable precursor. The invention also relates to a composition of matter that comprises sequences contained in NS3 and NS4A, and to the use of these compositions for the setup of an enzymatic test capable of selecting, for therapeutic purposes, compounds that inhibit the enzymatic activity associated with NS3. The figure shows plasmidic vectors used in the method to activate HCV NS3 protease in cultivated cells and in vitro.
