PCT/BG2016/000016"POBELCH - GLE" OODIVANOV, Ervin, Milenov
The invention relates to a method for extraction and separation of cannabinoids from industrial hemp, designed for medicinal purposes, and also the preparation of an extract, not containing tetrahydrocannabinol, and the preparation of maximum refined individual cannabinoids. The advantage of the method according to the invention consists in the preparation of an extract from hemp, which contains at a high percentage medically useful cannabinoids and doesn't contain undesirable admixtures and tetrahydrocannabinol, so that it can be used without any restrictions as a pharmaceutical. Moreover, the method allows the possibility of separation, if required, into individual useful cannabinoids as pure compounds, in ecological terms, without environmental pollution, as it is according to the most synthetic methods. The possibility of producing pure compounds represents a great contribution to the research of substances, related to a concrete medical application and the preparation of various combinations thereof, with the objective of expansion the field of application. The method is also cost-effective. The method consists in that the extract, obtained in accordance with various methods, undergoes a centrifugal countercurrent liquid-liquid chromatography, as the operation includes a centrifugation of solvents and the extract, obtained during the previous operations; the solvents form two phases, the phase, which the extract is dissolved in, is mobile, and the other one is stationary, whereby the mobile phase passes through the stationary phase, wherein several amounts of the components of the extract content are captured; this passing of the mobile phase through the stationary phase is repeated many times, until separation of the desired substances, which are analyzed in a familiar way, whereby as stationary phase solvents are used, which are selected from the group of straight-chain and branched-chain hydrocarbons, produced from crude oil, straight-chain and/or branched-chain alcohols, straight-chain and/or branched-chain ketones, straight-chain and/or branched chain carboxylic acids, straight-chain and/or branched-chain nitriles, gases in supercritical and subcritical condition, like carbon dioxide, nitrogen, nitrogen oxides, water with modified acidity with or without salts of organic and non-organic substances dissolved therein, as for example NaS03, carbonate compounds or mixtures of the above-mentioned solvents, and as mobile phase solvents are used, which are selected from the group of straight-chain and branched-chain hydrocarbons, produced from crude oil, straight-chain and/or branched-chain alcohols, straight-chain and/or branched-chain ketones, straight-chain and/or branched chain carboxylic acids, straight-chain and/or branched-chain nitriles, gases in supercritical and subcritical condition, like carbon dioxide, nitrogen, nitrogen oxides, water with modified acidity by organic and/or inorganic acids and bases, as well as Lewis acids and bases in the interval from 0 to 14 pH, with or without salts of organic and non-organic substances dissolved therein, as for example NaS03, carbonate compounds, or mixtures of the above-mentioned solvents, while the choice of the solvents between the two phases is conditional on that, they shall be different and immiscible with each other; the centrifugation revolutions and the flow speed of the mobile phase are designed (calculated or determined experimentally) depending on the total phase volume; thus at the finish of the process the tetrahydrocannabinols and/or the tetrahydrocannabinol acids are separated from the remaining cannabinoids and/or cannabinoid acids in the solution, the other cannabinoids in the process can also be separated as a pure substance, separate in a solution and the solvents are evaporated respectively, in order to obtain a pure substance.

6. WO/2016/179670 METHOD OF DATA INDEXING AND SORTINGWO17.11.2016
G06F 7/00
PCT/BG2016/000014STS SOFT ADTRONKOV, lliya
The invention is related to a method of data indexing and sorting on external storage devices through the establishment of specific indexing structure, characterized with the fact that it is established only through part of the incoming keys and operates through specific method of selection and merging of data buffers, in order to provide more effective external sorting of all data. The indexing method inherits the model with messages from buffer based trees, but makes a step further by allowing selection and multiple merging of buffers from various levels, and not only merging of subordinated buffers from a node to a slave node. With the method, the number of I/O operations, required for indexing and complete sorting of data is minimized. The method is applicable for database management systems, file systems, systems for sorting of big datasets, systems for parallel or distributed data processing etc.

A system and method for authentication, where the password do not have to be entered directly. It can be used to lock and unlock electronic devices. This system, protects passwords of being filmed, seen or recorded during the authentication process. The system is using numbers, letters, pictures and other graphical symbols which are randomly arranged in a matrix. Users are creating their passwords by choosing one or more symbols, which represent their passcode and they appear on the screen randomized and mixed with other symbols, every time. This system requires a new style of password typing, where the symbols will not be entered directly. Instead of clicking on the symbols, users have to slide over the rows or/and columns, containing the correct symbols. With every attempt for access the symbols are mixing and there have to be entered different combination of rows and/or columns.

The adjustable drip head will find application in the drip irrigation. It consists of a tube (2) in which an upper screw (3) with an inlet tube (4) and a lower screw (1 1) are screwed. There is a gap (6) between them wherein there is a movable upper cylinder (5) conveying the pressure via a pipe (7) through an obstacle (9) to a movable lower cylinder (10) with two drip holes (12) above it. The flow rate depends on the inlet pressure and the distance between the upper screw (3) and the lower screw (1 1) which is defined by the angle of its rotation ( a ). The desired flow rate is set via diagram 1 1 which is a function of a and the water pressure. Drip heads (1 ) bigger than 10 mm with more than two drip holes (12) for higher flow rates can be constructed. The allowed size of the sediments is below 0.5 mm which corresponds to the thickness of the gap (6).

PCT/BG2016/000010"PRINT CAST" LTDTODOROV, Georgi, Dimitrov
The method and system for layer-wise generation of three-dimensional objects from powdered material includes sequential application of powdered material and suitable binder onto a vertically mobile worktop (2). Depositing is performed by a powdered material application device (1) and a binder application device (3). The two application devices (1 and 3) work in two mutually perpendicular directions along two horizontal planes parallel to each other and the worktop (2), performing the application in both directions of movement between their final positions. Application devices (1 and 3) move and deposit the respective substance at a different optimal rate depending on the process. The method and the system have a wide range of applications in the casting industry for the layer-wise generation of complete sand molds and/or high precision cores directly from a three-dimensional computer model. They reduce the time required to produce casting shapes and improve the accuracy, and also allow the generation of more complex shapes without the need for a physical model.
