Granted: 2022-01-18
Abstract: FIELD: engine building.SUBSTANCE: method for operation of a free-piston gas generator (FPGG) and apparatuses for implementation thereof relate to engine building, in particular, to free-piston gas generators. In the first variant, a two-stroke FPGG operating on gasoline comprises two compression cavities and two alternately working combustion chambers in the cylinder. During the working stroke, gases spent in the previous working stroke are pumped into the turbine from the opposite combustion chamber. At the end of the working stroke, the residual spent gases are removed by blowing the combustion chamber, the chamber is filled to a predetermined pressure with compressed air, and after injecting fuel, another working stroke is executed. In the second variant, a two-stroke FPGG operating on an expanded range of fuels comprises a lockable pre-chamber next to each combustion chamber. During the working stroke in the first combustion chamber, gases spent in the previous working stroke are pumped into the turbine from the second combustion chamber. At the end of the working stroke, the residual spent gases are removed by blowing the first pre-chamber together with the combustion chamber, the pre-chamber is filled to a predetermined pressure with compressed air, and the air is held. A working stroke is executed in the second pre-chamber, prior to the completion whereof fuel is injected into the first pre-chamber, and after the ignition and necessary holding whereof, another working stroke is executed. Increased pressure and temperature are obtained by pumping the spent gases into the turbine. The operation of the gas generator on an expanded range of fuels is achieved by pumping a predetermined amount of air into a closed pre-chamber and by holding the burning mixture prior to the beginning of the working stroke.EFFECT: development of a method for generating gases with increased pressure and temperature necessary to increase the efficiency of the turbine, and development of variants of FPGG operating according to the proposed method.4 cl, 12 dwg

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to the field of medicine, namely to otorhinolaryngology. When planning an operation to close the perforation of the nasal septum, the dimensions of the perforation of the nasal septum are measured and its area is calculated. Then the preserved sections of the nasal septum are measured and their total area is calculated. At the same time, to close the perforation of the nasal septum with a flap on the feeding leg from the anterior latticed artery, the preserved sections of the nasal septum and the bottom of the nasal cavity located behind the perforation are measured. To close the perforation of the nasal septum using cross flaps of preserved tissues located above and below the perforation with the inclusion of a reserve of the mucous membrane from the arch and bottom of the nasal cavity, the dimensions of the preserved tissues of the nasal septum and tissues from the arch and bottom of the nasal cavity located above and below the perforation for each side are measured. The ratio of the perforation area and the area of the preserved sections of the nasal septum is calculated. If the size of the preserved tissues exceeds the size of the perforation by 20%, this makes it possible to form a vascularized flap of the required size to completely close the perforation.  
     EFFECT: method makes it possible to determine the ratio of the size of the perforation of the nasal septum and the preserved sections of the nasal septum to select the place of formation of vascularized flaps and the presence of branches of feeding vessels that can fully close the perforation of the nasal septum, improve the quality of surgical care and reduce the number of reperforation and residual caudal defects.

Granted: 1984-01-19
Abstract: A digital, bow-type measuring instrument is disclosed which provides rapid adjustment of the position of a measuring bolt with respect to an anvil over the entire measuring range. The instrument is used by rapidly translating the bolt into position such that the object being measured is positioned between the anvil and the bolt. Thereupon, the bolt is locked in position with the aid of a locking system so as to fix the measuring bolt in position with great rigidity while applying a predetermined measuring force to the bolt. In this way, an instrument is provided which makes possible precise measurements of heavy or fixed objects by means of a bow-type measuring instrument which allows rapid shifting of the measuring bolt.

Granted: 1985-10-24
Abstract: Zur Verhinderung einer Überfüllung von Tanks mit leicht entflammbaren Flüssigkeiten (Kraftstoffen) werden elektrisch betriebene Abfüllsicherungen eingesetzt. Die Abfüllsicherungen wirken dort mit Grenzwertgebern zusammen, die in den Tank eingebracht werden und beim Erreichen eines vorbestimmten Flüssigkeitspegels ein Signal auf die mit ihm verbundene Abfüllsicherung geben, so daß von dort eine mit der Abfüllsicherung verbundene Ventileinrichtung die Zufuhr der Flüssigkeit unterbricht. Grenzwertgeber können im Laufe der Zeit durch äußere und innere Einflüsse fehlerhaft werden und können somit ihrer Funktion nicht mehr gerecht werden. Um derartige Grenzwertgeber während des Betriebes als fehlerhaft zu erkennen, wird eine Anordnung vorgeschlagen, die leicht in schon vorhandene Abfüllsicherungsanordnungen eingebaut werden kann. Diese Anordnung umfaßt einen Vierpol (1), dessen beide Eingangsklemmen (2, 3) zum Anschluß des Grenzwertgebers (4) und dessen beide Ausgangsklemmen (5, 6) zum Anschluß des Schaltverstärkers dienen, so daß diese Anordnung auf einfache Weise zwischen Grenzwertgeber und Abfüllsicherung geschaltet werden kann.

Abstract: The intention is to provide an anchor which consists of solid material, preferably of flat material, and is intended for simply concreting into prefabricated concrete compound units. In said anchor, the expansion extensions can be adapted, in terms of material, size, shape and position, to a given loading, in particular the specific installation conditions of different prefabricated compound units, but the anchor can, nevertheless, be easily produced.   This is achieved in that, in the anchor consisting of solid material, the anchor shaft exhibits cutouts which are located, at a sufficient distance from its lower edge, in its longitudinal central plane, and in that there are provided expansion extensions which form insert parts separate from the anchor and are inserted in a positively locking manner in cutouts.
