Patent CA-2176337-A1 (CA)
Inventor: GREENLY JOHN B
IPC: H01J37/08
Filed: 1994-11-16
Abstract: An improved magnetically-confined anode plasma pulsed ion beam source (25). Beam rotation effects and power efficiency are improved by a magnetic design which places the separatrix between the fast field flux structure (408) and the slow field structure (414) near the anode (410) of the ion beam source, by a gas port design (404, 406) which localizes the gas delivery into the gap between the fast coil (408) and the anode (410), by a pre-ionizer ringing circuit connected to the fast coil, and by a bias field means (180) which optimally adjusts the plasma formation position in the ion beam source.
Patent CA-2176579-A1 (CA)
Inventor: SCHNEIDER REINHARD
IPC: C25D17/14
Filed: 1995-01-30
Abstract: The current density with which the process is used is of essential importance for the economy of a method of electrolytically treating materials. Normally only low or medium current densities are used, as the speed of replacement of consumed materials in the direct vicinity of the surface of the material for treatment has a restrictive effect on the magnitude of the current density at which a usable process result can still be achieved. However, a low current density leads to long electrolysis times and to complex treatment installations.       The opportunity afforded according to the invention of improving the transfer of materials at the surface of the material for treatment consists in generating a large flow of electrolyte at the treatment point by means of rotating electrodes which are movable synchronously with the surfaces of the material for treatment, and which may be electrically polarised with respect to the material for treatment, out of which the treatment agent emerges through openings, or into which it is sucked through openings.

Title: Methods and compositions for the detection and treatment of diseases associated with antigens of microorganisms
Inventor: CALENOFF EMANUEL J
IPC: A61K39/02
Filed: 1994-12-20
Abstract: A library of isolated and purified antigens specific for a micoorganism is a set of individual molecules. The library forms antigenantibody complexes useful in the context of diagnosing and treating conditions associated with a specific microorganism such as H. pylori-induced gastro-duodenal disease. For the antigen-antibody complexes in question the antibody is an immunoglobulin, which is IgE if the antigens are allergens. Complexes with IgA, IgG and IgM are also useful. By this multivariate approach, a specific condition is diagnosed with high sensitivity and specificity by determining whether complexes form between a specific antigen library and a biological sample which contains immunoglobulins from an individual. Such libraries also are useful for immunotherapy.

Title: Prevention of electrochemical and electrophoretic effects in food treatment systems
Inventor: BUSHNELL ANDREW H
IPC: A23L3/32
Filed: 1995-01-04
Abstract: Microorganisms are deactivated in a food product (10) using an electrode (16) placed into electrical contact with the food product. A current signal is applied to the electrode during a specified time period causing a deactivating charge to build up on the first electrode (16). An electrical field results from the deactivating charge having an electric field strength of at least 5.000 volts/cm. Substantially all of tile residual charge is removed from the first electrode (16) during a discharge period, such that an approximately zero net charge is delivered to the first electrode following the discharge period. thereby reducing electrophoretic side effects. The current signal causes an electrical double layer at the electrode to charge to a prescribed voltage. One embodiment, the prescribed voltage does not exceed a reaction voltage of a prescribed reacting material species for more than a prescribed threshold period, thereby reducing electrochemical reactions within the food product.

Patent CA-2204424-A1 (CA)
Inventor: DE MACEDO TORRES VANESSA
IPC: C22B/
Filed: 1997-05-02
Abstract: The present invention concerns the feasibility to economically exploit ores that contain gold and platinum metals, in which the recovery of platinum metals by the conventional processes is not feasible to be employed for ores that do not present occurrences of platinum metals and mineralogically associated sulfites.        The process to extract gold, silver and platinum metals from ores, concentrates and tailings according to the present invention is achieved through cyanidation under pressure, in which the material undergoes cyanidation in an autoclave with an alkaline solution (pH between 9 and 12.5), containing concentrations of cyanide between 50 and 15,000 mg/l.      The temperature and the pressure are controlled within the range of 40 to 300°C and 0.5 to 20 atm, respectively. Prior to the cyanidation under pressure, a cyanidation stage at room temperature can be conducted either followed or not by the adsorption of the extracted gold. After pressure cyanidation, the gold is recovered from the solution by adsorption/desorption, elutriation and electrolysis or cementation and the platinum metals by precipitation or by adsorption on the resin of the expended electrolyte.

Title: Feedback method for controlling non-linear processes
Inventor: FONTAINE ROBERT WILLIAM
IPC: G05B13/02
Filed: 1996-04-26
Abstract: A system controls a plant process (12) which includes manipulated variables (e.g. input states) and control variables (e.g. output states). The system includes sensor circuitry for providing measures of the control variables and a memory for storing a correction time constant and upper and lower limits for at least one control variable. The upper and lower limits are separated by a band of values within which the one control variable is considered to be acceptable. A processor includes data describing a process model (16) which relates costs of manipulated variables to control variables and, upon solution, further provides predicted values for the one control variable. Logic within the processor is responsive to a measured value function of the one control variable being outside the band of values, to determine minimum cost manipulated variables which result in a return of the predicted value of the one control variable to within the acceptable band of values. Control instrumentalities within the plant are operative to alter the manipulated variables (and input states) in accordance with signals from the processor.
