Patent LT-6821-B (LT)
Title: Gas sensor with capacitive micromachined ultrasonic transducer structure and functional polymer layer
Inventor: BARAUSKAS DOVYDAS
IPC: G01N29/00
Filed: 2019-08-14
Abstract: The invention relates to a gravimetric gas sensor for the selective detection of inorganic "acidic" gases, such as sulfur dioxide and carbon dioxide, in a gas mixture, without limiting the possibility of use with other gases. The sensor consists of capacitive micromachined ultrasonic transducer (CMUT) structure and functional material. The prior-art patents are close to this invention in that they rely on the measurement of changes in the CMUT structure resonant frequency. However, different functional materials are required to selectively detect different gases. The present invention is based on the use of functional polymers having specific properties, such as mPEI (methylated polyethyleneimine), without limiting the possibility of using other polymers having suitable properties. The problem is solved: more accurate, faster and more efficient gas detection and concentration measurement. The invention utilizes cross-sensor selectivity for different gases, achieved by refraining from modifying the sensor with different materials, instead employing more sophisticated measurement of detector dynamic parameters. CMUT structure is modified by functional material. The interaction with the gas changes the physical properties of the functional material (mass, modulus of elasticity), resulting in changes in the CMUT membrane loading parameters that are measured. The invention can be applied by mining companies, a wide range of household consumers.

Abstract: The invention relates to a method of operating a gas turbine unit comprising a combustion chamber, a high pressure turbine driven by gas from the combustion chamber, and a low pressure turbine driven by gas from the high pressure turbine, means for controlling the gas supply from the high pressure turbine to the low pressure turbine, and a low pressure compressor driven by the low pressure turbine, and a high pressure compressor connected in series with the low pressure compressor and driven by the high pressure turbine for supplying pressurized air to the combustion chamber, the useful power of the gas turbine unit being adjustable by controlling the gas conditions upstream of the low pressure turbine by said means. Substantially all the air delivered to the combustion chamber from the compressors, is utilized for the combustion in the combustion chamber. The generated gas is cooled with water and/or steam to a temperature which corresponds to the maximum operating temperature of the high pressure turbine. There is made use of the power obtained from the combustion chamber by said cooling, and the useful power of the gas turbine unit is recovered from the high pressure turbine at substantially constant rotational speed thereof. The temperature of the gas supplied to the high pressure turbine is maintained substantially constant independently of the useful power recovered from the gas turbine unit.

Patent SE-315981-B (SE)
Inventor: SCHREIBER P
IPC: A61M16/00
Filed: 1967-06-30
Abstract: 1,175,714. Respiratory apparatus. O. H. DRAGER [trading as DRAGERWERK, HEINR & BERNH. DRAGER]. 24 July, 1967 [22 July, 1966], No. 33979/67. Heading A5T. Respiratory apparatus of the kind including a breathing bag 4 in a closed chamber 5 in which positive and negative pressures are alternately produced, for inducing inhalation and exhalation respectively, of the patient, comprises an adjustable control device 7 including a valve 8 which shuts off the flow of gas from the chamber 5 when the negative pressure therein reaches a predetermined value which is adjusted by adjustment of the control device. The breathing bag is connected to a respiratory circuit 2 which includes a carbon dioxide absorber 2c inhalation and exhalation valves 2a, 2b and an anaesthetic supply conduit 1. When a changeover valve 17 actuated by a diaphragm 14 in response to pressure in a chamber 13 of the control device closes a vent 10a, gas is supplied by an injector 10 to the chamber 5 for the inhalation phase via a conduit 6 and the valve 8 comprising a cup 21 and an adjustably spring loaded diaphragm 18 which is exposed on one side to atmosphere and on the other to the pressure in the chamber 5. Simultaneously pressure builds up in the chamber 13. At a predetermined positive pressure in the chambers 5, 13, the valve 17 opens the vent 10a so that gas from the injector 10 passes to atmosphere and entrains gas from the chambers 5, 13 for the exhalation phase. At a pressure in the chamber 5 determined by the spring-loading of the diaphragm 18, the valve 8 closes shutting off the chamber 5 from the control device so that there is no further drop in pressure in the chamber 5. Further pressure reduction in the chamber 13 operates the valve 17 to close the vent 10a so that gas is again supplied to the chamber 5 for the next inhalation phase.
