Title: Methods and compositions employing unique mixtures of polar and neutral lipids for protecting the gastrointestinal tract and additional applications for surfactant replacement therapy and other conditions requiring rapid phospholipid _absorption to surfaces
Inventor: LICHTENBERGER LENARD M
IPC: A61K9/127
Filed: 1989-11-23
Granted: 1996-06-25
Abstract: Disclosed are methods employing compositions composed of unique mixtures of phospholipids and neutral lipids to treat the luminal lining of the gastrointestinal tract in the prevention or treatment of ulcerogenic processes such as peptic ulcer disease and inflammatory bowel disease.  Compositions including mixtures of saturated or unsaturated phospholipids, together with saturated or unsaturated triglycerides and/or sterols, are shown to provide a surprising ulcer protective efficacy in experimental models.  Further enhancement of activity is found upon the addition of a polyvalent cation or antioxidant to the various lipid mixtures.  The present invention also discloses unique methods employing mixtures of phospholipids and nutral lipids for surfactant replacement therapy in the treatment of the various forms of respiratory distress syndrome.  These compositions are shown to greatly enhance the surfactant replacement efficiency of surface-active lipids.  In this regard, experimental models have shown that both the surface-tension lowering effect and rate of phospholipid absorption to an air/liquid interface are accelerated by the addition of triglycerides and/or sterols to mixtures of saturated or unsaturated phospholipids.  Such compositions are therefore theorized to give new and enhanced therapeutic value to the use of surface-active lipids for surfactant replacement therapy in a subject without risk of immunogenic response.  The subject methods also comprise a simple, rapid and inexpensive means for the deposition of polar lipids to a variety of air/liquid interfaces.

Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE.          To permit easy change-over between double-prime, double-verso  (2/2) printing on a substrate web (5) and double-prime, single-verso (2/1) printing, the cylinders are arranged in printing couples to that first and second blanket cylinders (1, 2) are in printing engagement with each other, with the web (5) therebetween and printing couples including blanket cylinders (3, 4) independently of the blanket cylinders (1, 2) are in engagement with each  other, with the web therebetween. One (3) of the blanket cylinders of the printing couples is eccentrically shiftable from engagement with  the associated blanket cylinder into engagement with another blanket cylinder (2) so that said other blanket cylinder will function as an impression cylinder for one prime image, and as a printing cylinder for the verso image, while, at the same time, another prime image is being applied thereagainst by the shifted blanket cylinder (3).  The systems can be multiplied, preferably staggered vertically, with the substrate in form of a web being guided therebetween.  The system permits complete disengagement of the printing couple prior to shifting of the shiftable blanket cylinder, and thus avoids smearing of freshly printed subject matter.

Filed: 1992-03-19
Granted: 1997-04-15
Abstract: A  method  and  apparatus  for  recovering  lead  from  scrap lead/acid batteries involves first mechanically breaking up the batteries into small pieces, then feeding the small pieces into a substantially vertical,  upwardly diverging  separation/leaching column through which ammoniacal ammonium sulphate solution (AAS) passes upwardly at a speed that allows the removal of metallic lead and lead alloys as sinks from the bottom of the column,  with comminuted case material floating up and out of the column, while the lead compounds remain in suspension in the column for lead sulphate dissolution.  The insoluble lead dioxide from the pastes is removed from the AAS downstream of the column and is slurried with sulphuric acid to convert the lead dioxide to lead sulphate, which is then returned to the separation/leaching column.   The clarified AAS is fed to an electrowinning tank where metallic lead is plated out.  Make-up anhydrous ammonia is fed into the bottom of the column, while ammonium sulphate being produced from sulphuric acid neutralization and lead sulphate reduction is recovered for fertilizer.
