Title: Process for encapsulating oils containing products which produce a colour by reaction, microcapsules produced by said process and their use in carbon papers
IPC: B01J13/02
Filed: 1985-12-23
Granted: 1988-11-02
Abstract: A process for microencapsulating hydrophobic oils with color reactants, dissolved therein, of color reaction systems by reacting a water-soluble non-ionic melamine/formaldehyde precondensate and a water-soluble polymer in an oil-in-water dispersion for forming the capsule envelope is described. The special feature of this process is that, for stabilizing the oil-in-water dispersion, an aqueous solution of a cationic melamine/formaldehyde precondensate and the aqueous solution of a water-soluble polymer are mixed with vigorous stirring, a solid precipitating as a very fine suspension in the mixture, the mixture thus obtained and containing the very finely suspended solid is mixed with ther oil, containing the color reactant in solution, with vigorous stirring, the oil-in-water dispersion thus obtained in acidified and an aqueous solution of a water-soluble non-ionic melamine/formaldehyde precondensate is added with stirring, in order to form the capsule envelope. The use of the cationic melamine/formaldehyde precondensate leads to the precipitation of a very finely suspended reaction product thereof, whereby all the reaction systems in the course of the process are stabilized. Excellent capsules can be obtained without formation of agglomerates. The invention also relates to the microcapsules obtainable by the above process and to their advantageous use in color reaction recording systems.

Granted: 1994-01-05
Abstract: A process for producing cast unsaturated thermosetting resins which are highly stain resistant is disclosed. A pressurization step is applied to the thermosetting resin prior to casting to reincorporate any volatilized monomer which has volatilized during a previous deaeration step. The resultant casting is non-porous in cross-section which produces a product which is both stain resistant and machinable in the field without exposing voids.

Abstract: Self contained radio transmitting state estimator modules are mounted on power conductors on both sides of power transformers in electrical substations and on power conductors at various places along electrical transmission lines. They are electrically isolated from ground and all other conductors. These modules are capable of measuring current, voltage, frequency and power factor (or the fourier components thereof) the temperature of the conductor, and the temperature of the ambient air. The modules transmit these parameters to local receivers. The receivers are connected by an appropriate data transmission link, to a power control center which allows determination of the state of the power system. Appropriate control signals are transmitted back to the electrical switchgear of the system to bring it to the appropriate optimum state. Direct local control may also be effected, for example, the prevention of overloading a transformer. A <<donut>> state estimator module comprises a novel hot stick operated hinge clamp and a novel voltage sensor which measures the current between an isolated capacitor plate and ground. The donut measures the fourier components of voltage and current over a number of cycles and transmites the components to the local receiver. The local receiver derives the desired electrical measurements such as voltage, current, power factor, power, and reactive power and transmits them to local or remote control stations. Up to 15 donut modules may transmit on a single channel to a single local receiver. Each transmits at intervals which are an integral number. The intervals between transmissions of all donuts do not have a common factor and the average interval is the desired transmission rate. Each donut uses the zero crossover of current of its conductor to establish its transmission interval. The system is self-calibrating using known reference signals within the donut module.

Abstract: The process entails impurities which are dissolved and/or suspended in the waste water being separated out, by precipitation and/or flocculation (3, 9) and subsequent sedimentation (6, 12), as sludge, and the deposited sludge being, before it is further treated or dumped, dewatered in a sludge dewatering stage. The sludge is conditioned by adding kieselguhr and active charcoal (2, 4, 10), each in the form of a powder, to the waste water during treatment. This considerably increases, by utilisation of a synergistic effect, the ease of dewatering the sludge when conventional sludge dewatering devices are used. <IMAGE>

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.

Abstract: Metal values in non-ferrous metallurgical slag are recovered by gently agitating the slag in contact with matte using stirring energy dissipation rates insufficient to emulsify slag in matte. These low agitation rates conserve energy by reducing cooling of the charge, especially by reducing the period required for the slag and matte to separate out into distinct layers after agitation. The preferred low energy dissipation rates increase the efficiency of the value metal recovery and avoid or reduce impairment of the reducing capabilities of the matte and hence its capabilities for reducing and collecting oxidized value metal species from the matte. This is achieved by avoiding or reducing oxidation of the matte as a result of dispersal of the oxidation-protective overlay of slag and contact of the matte with the ambient oxidizing atmosphere.

Abstract: In a multi-stage cooling process for hot pyrolysis gas formed by degassing of plastic wastes or the like in a pyrolysis reactor, the hot pyrolysis gas is cooled by direct heat exchange in the first cooling stage (10) immediately downstream of the pyrolysis reactor. The cooling medium used here is a low-boiling pyrolysis oil which is obtained by condensation of pyrolysis gas in a cooling stage (32) which is located downstream of the first cooling stage. As a result, separate cooling and purifying measures for the pyrolysis oil are unnecessary. <IMAGE>
