Abstract: IMPROVED CONDENSATE POLISHING SYSTEM   INCORPORATING A MEMBRANE FILTER                       ABSTRACT         A method and apparatus for polishing a condensate is provided wherein the condensate contains both suspended and colloidally dispersed solid impurities, and also intermittent and variable levels of ionic impurities and dissolved silica.  When the ionic impurities exceed a preselected level, a finely divided ion exchange resin mixture is first admixed with the condensate at a rate sufficient to reduce the level of such impurities to a preselected level within a preselected contact time period.  Thereafter, the resulting condensate is passed through a membrane filtration device to remove such suspended and dispersed solid impurities.  A simple, effective and reliable retrofittable apparatus adapted for use with BWR'8 fitted with precoat filter systems is provided.

Title: Inhibition of lymphocyte adherence to vascular endothelium utilizing a novel extracellular matrix receptor-ligand interaction
Inventor: WAYNER ELIZABETH
IPC: A61K39/395
Filed: 1990-08-31
Abstract: The present invention relates to a method for inhibiting the adhesion of one cell to another comprising interfering with the interaction between the extracellular matrix receptor and its ligand. The invention is based upon the discovery that the .alpha.4.beta.1 extracellular matrix receptor promotes adhesion of lymphocytes to endothelial cells via attachment to a defined peptide sequence. Prior to the present invention, the ligand of the .alpha.4.beta.1 receptor had not been identified, nor had the function of the .alpha.4.beta.1 receptor in lymphocyte attachment been known. By preventing the interaction between the .alpha.4.beta.1 receptor and its ligands using antibodies or defined peptide sequences, the present invention enables, for the first time, specific intervention in the migration of lymphocytes through the vascular endothelium and into tissues. The present invention, therefore, has particular clinical utility in suppression of the immune response; in various specific embodiments of the invention, the adherence of lymphocytes to endothelium may be inhibited systemically, or may, alternatively, be localized to particular tissues or circumscribed areas. Accordingly, the present invention provides for treatment of diseases involving autoimmune responses as well as other chronic or relapsing activations of the immune system, including allergy, asthma, and chronic inflammatory skin conditions.

The suspension includes a tapered, vertically mounted elongated arm having an integral eye at one end. The integral eye rotatably connects the elongated arm to the vehicle while the other end connects to an air spring attached to the vehicle. The axle connects to the arm near the air spring. The arm is tapered between the axle and the integral eye so that the amount of arm material, and thus weight, is reduced. A second arm is placed adjacent to, and parallel with, the first arm to back up the first arm if the first arm fails, or vice versa. A shock absorber is mounted near the axle on the opposite side of the axle as the air spring. The method of manufacture includes plasma cutting a blank elongated arm from spring steel, heat-treating the arm, machining to final form, and then shot peening the arm.

Abstract: An initial curvature is cut into a lens blank in a lens making machine, such as a lathe, and the curvature is subsequently finished by a finishing tool. The finishing tool has curve characteristics which correspond to those of a prescription within a prescribed tolerance. The curvature of the finishing tool is measured on a digital gauge, and those measurements are fed to a digital controller which actuates the lathe. As a result, an initial curvature is cut into the lens blank having characteristics which correspond to those of the finishing tool. The finishing operation can thus be performed more quickly, since less material needs to be removed from the initial curvature during the finishing operation. <IMAGE>
