An automotive engine has a turbocharger, a wastegate valve for controlling flow rate of exhaust gas applied to a turbine of the turbocharger, and an actuator for controlling the wastegate valve. A standard supercharging pressure is determined dependent on characteristics of the wastegate valve, and a desired supercharging pressure is set in accordance with engine operating conditions. A difference...

The invention relates to a method for thin needle biopsy in connection with mammography, wherein a stationary target is radiographed from two angles by means of a rotating picture head, the pictures are placed on a separate measurement table, and the x-, y-, and z-coordinates of the desired site in the target are calculated on the basis of the two pictures in a known manner. In the method, measuri...

An apparatus (10) and related process for enhancement of woven and knit fabrics through use of dynamic fluids which entangle and bloom fabric yarns. A two stage enhancement process is employed in which top and bottom sides of the fabric are respectively supported on members (22, 34) and impacted with a fluid curtain including high pressure jet streams. Controlled process energies and use of suppor...

System comprises: (a) 3 containers (C1, C2 and C3) where C1 and C2 and C2 and C3 are in fluid communication; (b) a first porous medium interposed between C1 and C2 (LDM) comprising at least 1 of a leukocyte depletion medium, a red cell barrier (RCBM) and a combined LD-RCBM; and (c) a second porous medium interposed between C1 and C2 comprising a leukocyte depletion medium. Also claimed is a blood ...

The (R) or (S) isomer of acetorphan or N-/2-acetylthiomethyl)-1-oxo-3-phenylpropyl/(S) alanine methyl ester is prepared by splitting of racemic acetylthio-2-benzylpropanoic acid by reaction with ephedrin, separation of the enantiomeric salt obtained, then freeing of the acid and coupling with the corresponding amino acid ester. The obtained preparations possess remarkable therapeutic activities an...

This invention relates to a gas assisted flotation process and apparatus useful in the separation of solids from liquids in a slurry, such as treated waste waters, paper pulp solutions etc. The gas assisted flotation process may be operated on a continuous basis. The upper portion of the main chamber of the apparatus (36) is tapered inward to terminate in an apex (38) which has an opening through ...

In order to accommodate a relatively large number of paper storage reels (11-17) with diameters of relatively large size in correspondence with a relatively large paper reservoir in a space of relatively small dimensions, storage reels (12-15) are also arranged in side-by-side relationship, i.e. laterally offset with respect to the paper feed slots (21-27) of the printer (20). The path segments of...

The utility model relates to a sanitary facility, particularly an improved self-pressing solar shower bath device. The utility model takes tap water as power, and takes solar energy as a heat source, so that hot water can also be ejected by cold water even when the self-pressing solar shower bath device is installed at an earth surface height outdoors. The self-pressing solar shower bath device is...

Winding apparatus for a continuously running thread The winding apparatus has a bobbin revolver (18), on which two bobbin spindles (5.1) and (5.2) are mounted for alternate operation. The bobbin spindle currently in winding operation rests with its circumference on a contact cylinder (11). The bobbin revolver is rotatable to adapt the axial distance between the contact cylinder and the bobbin...
