Title: Method for diagnosing asthmatic bronchitis in process of lung auscultation in adults
Inventor: ARTEMENKO MIKHAIL VLADIMIROVICH
IPC: G06F17/14
Filed: 2021-03-05
Granted: 2022-03-15
Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, particularly to pulmonology and functional diagnostics, and aims at diagnosing asthmatic bronchitis in pulmonary auscultation during examination of a patient using an electronic stethoscope. Method for diagnosing asthmatic bronchitis in the process of auscultation of the lungs of adults involves recording a respiratory noise in a point above the larynx region using an electronic stethoscope for 30 seconds, followed by sampling the signal in a computer with a sampling rate of 4 kHz. Further, calculating the value of the indicator variable Id as the average value of the squares of the elements of the main diagonal of the RR matrix, which is the product of the reference matrix Re corresponding to the signal of a person having no respiratory disease by the bispectrum matrix 
       ,  
     where   is the third-order sample moment (bispectrum matrix element), x(i) is the i th  sample of the recorded respiratory noise signal x(t), I is the number of samples of the discrete signal x(t), k and l are the indices readings of time shifts from a plurality of {0, 50, 80, 100, 140, 190}. Then the patient’s state is correlated with the following groups: “patient is healthy”, if Id ⸦ [0; 4], “presence of asthmatic bronchitis is highly probable”, if Id ⸦ [32; 50], “additional examination is required”, if the value of Id is not included in the specified intervals. 
     EFFECT: increased noise immunity of respiratory sound recording during lung auscultation using an electronic stethoscope and the efficiency of automated diagnosis of asthmatic bronchitis by calculating a certain indicator variable for the examined patient and comparing its value with the threshold value previously determined on a representative sample of healthy people.

Granted: 1982-07-01
Abstract: The object of the proposed circuit is to provide a simpler construction than earlier designs. The alarm relay unit (ME1) is activated by a contact (m1) associated with some external apparatus which is being monitored. When this contact closes the alarm relay (D1) picks up through the audible warning circuit (H1,h11). When this occurs the relay seals in via one of its contacts (d14), at the same time arming the accept relay. The audible alarm may now be stopped. Pressing the accept button (qu) energises and seals in the accept relay (D2). When the cause of the alarm has been removed and the initiating contact (m1) is open the cancel button (18) clears the whole circuit back to its original state. The accept relay is non polarised and remains in the state in which it was last set. PS.

Title: Zahnkupplung
IPC: F16D3/18
Filed: 1981-06-12
Granted: 1984-04-26
Abstract: Bei Zahnkupplungen müssen zur Schmierung der Verzahnungen die Kupplungsgehäuse mit Öl oder Fett gefüllt werden. Durch das Spiel zwischen Paßfeder bzw. Keil und Nabe kann Schmiermittel von innen nach außen austreten, insbesondere dann, wenn hohe Zentrifugalkräfte auftreten. Zur Abdichtung wurden bisher die inneren Nabenstirnseiten mit Hilfe von Nabenkappen oder inneren Verschlußplatten abgedichtet. Diese Lösung hat sich jedoch nicht bewährt, da sich die Nabenkappen wegen ihrer Dünnwandigkeit häufig von selbst lösen, bei der Montage teilweise schief aufgepreßt werden, oder schon beim Transport verloren gehen. Die Herstellung von Nabenkappen oder inneren Verschlußplatten ist aufwendig. Bekannt ist ferner die Abdichtung durch Verstemmen der Nuten innen oder außen mit Blei, was erhebliche Kosten verursacht. Zur Vermeidung dieser Nachteile werden erfindungsgemäß die Zahnkupplungen an ihren inneren Nabenstirnseiten und Wellenenden mit dünnschichtigen, zerreißfesten Folien versehen. Hierdurch ist bei minimalem Arbeitsaufwand eine einwandfreie Abdichtung bei neuen und bei bereits in Betrieb befindlichen Kupplungen möglich.
