Granted: 1988-10-13
Abstract: An electrical circuit for the graphic processing of resulting contours of several polygonal superposed images stored in memory. Such images, commonly used for numeric machine tool controls, graphically represent a workpiece as sectional contours. The circuit of the present invention, after initialization, determines the inner and outer polygonal contour of the resultant superposed images. The processing speed of the present invention is one to two orders of magnitude greater than the corresponding processing speed of comparable software programs. This high speed processing enables the present invention to represent the effect of a machine tool on a workpiece in three dimensions in real time. By combining this circuit with additional components a relatively inexpensive high speed graphics processor can be created.

Abstract: Friedel Crafts preparation of arylene ether (especially arylene ether ketone) oligomers with an exceptionally high degree of isomeric purity and freedom from by-products can be achieved by adding to the Lewis acid reaction system a protic controlling agent selected from ROX, water, RCOOX, RSO3X, and ROY, wherein R is organic, X is hydrogen or metal, and Y is metal. Contrary to conventional expectation, the protic agent does not significantly acylate or alkylate the Friedel Crafts reaction product, and controlling agents of relatively low molecular weight, e.g., benzoic acid, can surprisingly be selected to produce dispersions of the resulting oligomers.

Abstract: A method is provided for obtaining a vaccine against the different pathogenic serotypes of group B Neisseria meningitidis characterized by starting from live microorganisms of any one of the known pathogenic serotypes of the B group without inactivation, from which the extractation of the vesicles of the outer membrane and the protein antigenic complex of 65 - 95 KD molecular weight is carried out using detergent, enzyme and ultrasound combined in the treatment. The resulting product, after treatment to eliminate the nucleic acids, is purified by a dissociating treatment with detergent, ultrasonic bath and column chromatography. The multi-antigenic material so obtained is purified to obtain the protein antigenic complex of 65 - 95 KD molecular weight for HPLC chromatography (TSK 3000 SWG column) or affinity chromatography with monoclonal antibodies, or hydrophobicity chromatography, or ionic exchange chromatography or a combination of any one of them. The protein antigenic complex is then added to the fraction that contains the vesicles by ultrasound treatment so that it will be anchored on then, in a proportion of 15 por cent +/- 3. The capsulr polysaccharide is also added, in a proportion of 1.1 - 1.4 with respect to the protein and the adjuvant in a relation ranging from 2 - 100 mcg/protein mcg. The different components ot the mixture may be sterilized by cobalt 60 inonizing radiations with doses from 5 - 25 Kgy and a temperature between 1 - 4 grade C before preparing the mixture or the resulting mixture may be sterilized by this procedure.

Abstract: A method of treating humans suffering from central nervous system diseases, such as Alzheimer's disease, cerebral atrophy, Parkinson's disease, senile dementia, senile tremor, essential tremor, multiple schlerosis, cerebovascular accidents, and cerebellar atrophy, as well as diseases where dementia is present. The treatment consists of inducing into the patient's blood stream at least one from the group consisting of: sex hormones and anabolic hormones. (HGH, NCG, trophobostic hormone). Ergolid myselates, dopamine, cathecoline, serotonin, amphetamine may be used in conjunction with the hormone, as well as a vasodilator and non-steroid anti-inflammatory. Growth hormone may also be used in those patients in advanced stages of the disease, or in those patients where it has been determined that a low level of growth hormone is present, clinical deterioration not having been corrected by other hormones. A method of diagnosing Alzheimer's disease, senile dementia, by the determination of the levels of the hormones somatotropin(human growth hormone) and somatomedin-C (IGF-I) after the administration of the Aroonsakul-Allen provocative test. Blood-sera samples are taken every thirty minutes for a two hour period after the administration of L-Dopa, and the samples are tested for the levels of these hormones. These levels are then compared against the levels for normal subjects in the age group of between fifty years and sixty years. If the levels of the patient being diagnosed falls below the statistical mean corrected for error, then a diagnosis of Alzheimer's disease is indicated what is equivalent to severe HGH deficiency, mild and moderate, HGH deficiency indicating senile dementia in early and late stage.
