Title: Method of stripping electrolytically deposited copper  from a cathode
Inventor: MIDDLIN BRUCE
IPC: C25C7/08
Filed: 1987-11-03
Granted: 1993-05-18
Abstract: ABSTRACT     A Method of Stripping Electrolytically Deposited Copper from a Cathode Electrolytically deposited copper is stripped from a cathode by first flexing the cathode to cause at least part of the copper deposit to separate from the cathode, and then wedge-stripping or gas-blasting the remainder of the copper from the cathode.  Perferably the cathode is a stainless steel sheet, and flexing is achieved by means of hydraulic rams which press the centre of the sheet first in one direction and then in the opposite direction.   The cathode is supported along its bottom edge and held upright during the process.

IPC: A61K9/64
Filed: 1987-12-14
Granted: 1993-10-19
Abstract: Abstract of the Disclosure Methods are described for targeting the release of an active pharmacological agent in an animal by administering that agent encapsulated in proteinoid microspheres which are stable to the environment encountered from the point of introduction until they migrate to the targeted body organs, fluids or cells and are there unstable.  Orally administered delivery systems for insulin, heparin and physostigmine utilize encapsulating microspheres which are predominantly of less than about 10 microns in diameter and pass readily through the stomach wall and which are made of an acidic proteinoid that is stable and unaffected by stomach enzymes and acid, but which releases the microencapsulated agent in pharmacologically active form in the near neutral blood stream.          Basic proteinoid microspheres encapsulating a dopamine redox carrier system are administered in the lower gastrointestinal tract, where they are stable, and then enter the blood stream, where the encapsulated agent is similarly released.

Title: Asymmetric heat exchange reaction apparatus and method for effecting chemical reactions
Inventor: SILLERUD DEAN R
IPC: C02F11/08
Filed: 1988-01-21
Granted: 1992-09-01
Abstract: 208J.114 ABSTRACT OF THE DISCLOSURE   In accordance with the present invention there is provided a reaction apparatus having an externalized heat exchange mechanism by which heat may be added to or withdrawn from a reactant mixture. In one aspect, the present invention includes a cased well which extends approximately 5000 feet vertically into the earth in which at least one reaction vessel is suspended from a support plate at substantially ground level surface. The reaction vessel comprises an outer closed-end tube in which an inner open-end tube is disposed in a concentric manner to define an annulus which is in flow communication with the bore of the inner tube. Substantially parallel to the reaction vessel and also suspended from the ground level support plate, is a conduit which extends into the chamber defined by the well-casing. In the method of the present invention, a mixture of reactants, preferably diluted municipal waste, is injected into the annulus of the reaction vessel to form a hydrostatic column which exerts substantial fluid pressure at a reaction zone in the lower part of the reaction vessel. A heat-transfer medium, such as oil, is heated to an elevated temperature and then flowed through the conduit into the chamber where the hot heat-transfer medium envelopes the reaction vessel. Heat is transferred from the heat-transfer medium to the reactant mixture through the wall of the outer closed-end tube. In the case of an exothermic reaction, when the temperature of the reactants reaches a selected level, the reaction process gives off heat which is withdrawn by the heat exchange medium. As the reactants form reaction products, the reaction products are flowed from the annulus through the bore of the inner tube back up to ground surface level.     In another aspect more than one reaction vessel is suspended in a single chamber in a single subterranean shaft. In still another aspect of the present invention, a reaction apparatus is provided in which each reaction vessel comprises an inner open-end tube concentrically 2086.114 arranged inside at larger intermediate closed-end tube which is then surrounded by a larger tube to form a heat exchange annulus. Also suspended in the chamber with the reaction vessel is a conduit through which heat-transfer medium is pumped into the chamber during operation. The chamber is partitioned into an upper portion and a lower portion by packing assemblies or by pressurizing the upper portion with an inert gas. As heat-transfer medium flows into the chamber it is confined to the lower portion of the chamber and forced upwardly through the heat exchange annulus which is in heat-transfer relation to a hydrostatic column of reaction products in the inner reaction vessel annulus.

Abstract: ABSTRACT OF THE INVENTION         By the use of  small amounts of novel amide resin reaction products of dibasic dimerized or trimer-ized fatty acids,  an alkanolamine and a polyalkylene polyamine, improved drilling mud formulations are ob-tained.   In those oil mud drilling formulations that contain organophilic clays, one is able to maximize the viscosity and gelation of the formulations, resulting in less preparation time and less material usage, es-pecially the clay.  In accordance with the invention, one is able to thicken or gel oil-mud systems at usual operating temperatures even when using low viscosity/ low aromatic oils as the external phase, and to maximize the yield  of  organophilic  clays  readily  in a short period of time, at low shear rates.  The amide resin extends the utility of organophilic clays in low vis-cosity oil-mud systems.  They produce more shear thin-ning fluids, higher yield points and quicker gel stre-ngths while maintaining low plastic viscosities.
