Title: Composite crankshaft
Inventor: IVANSHCHIKOV YURIJ VASILEVICH
IPC: F16C3/12
Filed: 2021-01-12
Granted: 2021-07-14
Abstract: FIELD: mechanical engineering.SUBSTANCE: invention relates to the field of mechanical engineering, and more specifically to the crank mechanisms of internal combustion engines of automotive engines. The composite crankshaft includes separately manufactured support links. Each support link is pre-fabricated separately and is a single element. The supporting links consist of the main journals and two cheeks located in two parallel planes perpendicular to the axis of the main journal. On the ends of each cheek, grooves are made for installing a separately manufactured connecting rod link in them. The outermost support links - front and rear - also represent one-piece, single elements. The front support link includes a support journal, on the left of which, perpendicular to its axis, there is a cheek with a groove on its end, and on the right, an end for installing the gears of the drive of engine mechanisms. The rear support link includes a main journal, on the right of which the cheek is located perpendicular to its axis, and on the left is a flange for installing a flywheel. A groove is also made at the end of the cheek piece for installing the connecting rod journal. The assembly of the shaft is carried out directly during the general assembly of the engine. One of the advantages of the composite crankshaft of the proposed design is that it can be assembled on engines with a different number of cylinders by changing the number of support links. The connecting rod journals in the grooves on the ends of the cheeks are installed and fixed with a cover and two bolts through a set of adjustable liners. This design allows, if necessary, to adjust the piston stroke (increase or decrease).EFFECT: increasing maintainability in the event of failure of individual connecting rod or main journals, reducing the number of operations (in increasing productivity) when removing the connecting rod-piston group from the block and installing it back into the block, versatility (adaptability) of the proposed design of the crankshaft for engines with different numbers of cylinders, as well as expansion of the field of application, as well as the possibility of changing the compression ratio in the combustion chamber of automotive engines.2 cl, 10 dwg

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to neurology, and can be used for prediction of neurological recovery of patients in period from 14th to 90th days of ischemic stroke of brain. For this purpose, on the 14th day of acute ischemic stroke, serum concentrations of the basic myelin protein (MBP), antibodies to it (anti-MBP), vascular endothelial growth factor (VEGF), brain neurotrophic factor (BDNF) are determined, functional independence on the Phekin scale (mRS) and neurological deficiency on the Stroke Scale (SSS) scale is evaluated. The probability of neurological recovery of F on the 90th day in accordance with the developed formula is then considered. If F > 0.5, a high probability of neurological recovery from the 14th to the 90th day of ischemic stroke is predicted, if F < 0.5, the patient is unlikely to be reduced. 
     EFFECT: method makes it possible to carry out combined assessment of activity of processes of neurogenesis and angiogenesis, protective-compensatory, humoral reactions and degree of damage of myelin sheath of corticospinal tracts and can be possible to solve the problem of dosed rehabilitation interventions in early recovery period of ischemic stroke, which is most sensitive from point of view of structural and synaptic neuroplasticity, and also allows to achieve regression of neurological deficiency and increase functional independence personalised for each patient.

Abstract: Die Erfindung betrifft ein Verfahren zur schmelzmetallurgischen Behandlung von Legierungen mit Entmischungstendenz unter Unterdrueckung von Schwere-bedingten Entmischungserscheinungen. Das Verfahren ist dadurch gekennzeichnet, dass die Legierung unter Vakuum aufgeschmolzen, durchmischt, in Wasser zu einem Legierungsstab abgeschreckt und dass anschliessend eine infinitesimal duenne schmelzfluessige Zone der Legierung den Stab unter gleichzeitiger Kuehleinwirkung im Vakuum durchlaeuft.

Abstract: Speech sound recognition is made using a reduced number of speech parameter elements, e.g., five correlation coefficients rather than sixteen spectral coefficients. The five correlation coefficients are derived from comparison of the spectral coefficients of unknown or standard sounds against the spectral coefficients of five highly-separable vowel-like sounds. Then, unknown-sound correlation coefficients are compared with standard-sound coefficients for recognition.

IPC: F02B3/06
Filed: 1980-09-29
Granted: 1986-04-30
Abstract: The engine cylinder head is fitted with fuel injection offset from the throat area in a conical combustion chamber. To ensure uniform mixing and combustion, the angle (gamma) between the axes (15,16) of a pair of adjacent injection jets (10,11) directed onto the chamber and projected onto the cross-sectional plane of the chamber (4) should be 1.8 to 2.2 times the angle (delta) formed by any pair of adjacent jet axes directed onto the opposite chamber wall (6,4). As air whirls inside the chamber, fuel is injected through the channel system (10-14) along axes (15-19) to contact the wall at arrowed points (20-24). The radial air flow intersects the fuel jets at given angles move atomised fuel to the chamber centre. The jet tips remove combustion products by sweeping them round to the throat (7). In the expansion phase the fuel vapours are deflected towards the unused chamber air on the opposite side so that the air supply is totally utilised.
