Title: Method for obtaining intact amorphous silica and high-purity silicon from plants and the device used in said method
Inventor: DIKINIS LEONAS VIRGAUDAS
IPC: F23G5/00
Filed: 2019-08-20
Abstract: The present invention can be used in pharmacy. Pure silicon can be used in computer technology, where the purity requirements for the materials are high. The object of the invention is to provide a more economical, safer and more environmentally friendly method for obtaining intact (natural) amorphous silica and subsequently 99.99999999% (N10) purity amorphous silicon. Amorphous silica can be obtained from oats, rice straw and rice husks by minor modifications of the devices. The raw material is processed in two different temperature modes: heat, where the temperature does not exceed +450 °C, and cold, where the temperature is maintained from -35 °C to -40 °C. The wet "white soot" mass obtained during the pyrocatalysis process is transported in a closed pneumatic conveyor, the inside of which is covered with a silicon-inert coating. The pressure in the system is generated by the compressor. The obtained raw material contains 93 - 95 % amorphous silica, its content depends on the variety of rice, soil, harvesting time and especially on the condition of the straw. The purity of the amorphous silica is 99.9999999% (N9) by cleaning the raw material, which is recycled in two washes, and by using two magnetic traps. The wave reactor works with three energies at once: heat, microwave, and sound. 99.99999999% (N10) purity amorphous silicon is obtained. Heating and cooling takes placeinside the units. Thermoregulation is performed by means of Þ. Rankë pipes.

Abstract: A side web non-pneumatic tire ("SWNPT") is integrally molded from a stiff, resilient elastomeric material with particular specifications, to form a unitary honeycomb structure bounded by integrally molded outer and inner cylindrical coaxial and coextensive members ("hoops"), and, a single side web member. The outer hoop is supported and cushioned by the honeycomb which comprises a plurality of circumferentially spaced apart, angularly oppositely directed planar rib members (ribs) bounded by the side web on one side only. The side web, preferably on the outboard edge of the hoops, connects the hoops near their outboard edges. The opposite side surfaces of the side web lie at an angle  theta  in the range from 0 DEG  to 30 DEG  on either side of vertical to the rotational axis of the SWNPT. The ribs extend axially along the inner and outer hoops, connecting them, and the outboard edges of all the ribs lie upon the inboard face of the web. The ribs on each side are angled at opposite angles in the range from 15 DEG  to 75 DEG  to radial planes which intersect them at their radially inner ends. A rubber tread is secured to the outer surface of the outer hoop. The coaction of the structural elements of the SWNPT provide a load-supporting structure which, in operation, is subjected to continuous compression and tensile forces as it travels over the ground. Deformation and buckling characteristics of the SWNPT are derived from the honeycomb structure of an elastomer which provides the SWNPT with "ride" and "handling" comparable to those of a conventional pneumatic tire. The outer hoop has a vulcanized rubber tread secured to the hoop's outer surface to withstand travel over a road surface. The unribbed face of the single side web may be faced with an elastomeric sidewall to resemble the sidewall of a conventional pneumatic tire.

Abstract: Redried cut rag tobacco is directly sprayed with one or more pre-selected alcohols. These are capable, when the vapours are inhaled by the smoker, of inhibiting or blocking the selective localisation of at least one nitrosamine and/or a metabolite thereof in the smoker's tissues such as those of the epithelial lining of his lungs. An example of such an alcohol is cyclohexanol in an ethyl alcohol solution. After the alcohol solution has been sprayed on the tobacco, pref. as it tumbles in the cooler cylinder of the mechanised cigarette making line, and allowed to dry, the tobacco is made or machined in a conventional manner into the final cigarette, either filtered or unfiltered. The blocking alcohol is then efficiently heat released into the tobacco smoke stream as the cigarette is smoked, resulting in the desired blocking effect in the smoker, without noticeably altering the customary smoking experience and satisfaction.

Abstract: A modulation circuit is used in a GMSK modulation system. The system includes I-channel (210) and Q-channel (212) ROM look-up tables, each preprogrammed for generating a representative digital waveform based on an input data stream (250) and a clock signal (252). Each digital waveform is converted to an analog signal for subsequent radio frequency (RF) modulation. Each ROM is addressed by an interpolation counter (224) controlled by the clock signal (252), by a data shift register (226) receiving the input data (250) at a rate corresponding to the clock signal, and by a quadrant register (230), also receiving the input data for specifying the phase of the data signal with respect to the clock signal. Additionally, a signal (242) indicating the arrival of a non-integer bit interval is provided. In response to this signal, ROM addressing is updated in order to provide control of the modulated carrier's phase angle.

Abstract: The invention relates to a process and to the device for controlling and guaranteeing safe operation of heating appliances not connected to a chimney and especially oil- based heaters indoors, under both normal conditions and conditions falling outside the latter. Outside the normal conditions of normal heating there is the danger of incomplete combustion occurring, with the consequent reduced levels of O2 and increased levels of CO2 in the indoor air. The objective of the invention is to enable the level of CO2 in the indoor air to be controlled rapidly and precisely and to guarantee, independently of the intensity of the flame of the burner, that the oil- based heater can be adjusted and safe operation thereby guaranteed, independently of the detection of the intensity of the flame sensitive to radiation. In accordance with the present invention, the said objective is achieved by measuring the level of O2 in the combustion gases of the burner inside the oil-based heater sensitively and using this value as a measurement for controlling the level of CO2 in the indoor air and converting a tension (voltage) signal to be used as control signal, in which, during operation of the burner outside a preset range of intensity of flame, use is made of the said O2-sensitive detector both for reestablishing a normal heating condition and for regulating operation at a minimum flame intensity and the production of an alarm signal and automatic delayed snuffing-out of the burner which take place at a first and at a second predetermined level of O2 in the combustion gas of the burner, respectively, corresponding to predetermined levels of CO2 in the indoor air, the second level being lower than the said first level. In addition, means are installed for detecting, sensitively, the level of CO in the combustion gas of the burner inside the oil-based heater and also for using the said level as a measure for adjusting the level of CO2 in the indoor air, after conversion into a corresponding control signal.

Abstract: A continuous flow of combustion products which are led through a chamber 22, are mixed with air mixed with moisture and ignited by the spark from a spark plug 40 which is connected to the high-voltage terminal 42 at a secondary winding of an ignition coil 44 having a primary winding connected between a DC voltage source and a terminal 52 which is exposed to a gas mixture in the chamber 22. The high voltage applied to the spark plug is induced by intermittent interrupting of the current through the ionised gas mixture which is grounded in the chamber 22 as a consequence of limited in-flow of the air mixed with moisture into the chamber 22. <IMAGE>
