Granted: 2021-05-19
Abstract: FIELD: polysaccharide chemistry. 
     SUBSTANCE: method for producing hyaluronate includes washing the byproduct with running water, grinding it, extracting, filtering and combining the extracts. As the raw material, frozen or fresh animal byproducts are used, selected from chicken comb, cattle skin and eyes. After washing, the byproduct is denatured by dehydrating it with a saturated solution of sodium chloride, decontaminated with a compound of active oxygen, and placed in distilled water to swell. The cycle of dehydration, decontamination and swelling is repeated at least once, after which the dehydration and decontamination are repeated. The denatured material is crushed and homogenized, and three-fold extraction is carried out from the crushed denatured material with 0.85-0.9% sodium chloride solution at a temperature of 35-40°C with the separation of the meal by vacuum filtration on metal grids. Then, the extracts are combined, and fermentolysis is carried out when vacuumed with an enzyme complex including the papain, pepsin, trypsin enzymes and phosphodiesterase at a temperature of 30-35°C for 24-36 hours at a pH of 6.5-7.2. The fermentation mixture is heated to 70-80°C, quickly cooled to 5-10°C, and the lipid membrane is separated. Then, sequential ultrafiltration is performed with a final membrane with a pore size of no more than 0.2 mcm. The hyaluronate is precipitated with cetylpyridinium chloride. The precipitate of cetylpyridinium hyaluronate is dissolved in 0.9-1.2% sodium chloride solution to a concentration of no more than 0.15%, and the solution is filtered through a membrane with a pore size of no more than 0.2 mcm. Then, a solution of hyaluronate with a concentration of no more than 0.15% is prepared, followed by purification and separation of the hyaluronate into fractions by cascade filtration in a continuous cycle by reverse osmosis, and the finished product is obtained.  
     EFFECT: invention makes it possible to obtain substances of matrix hyaluronate of various molecular weights of high fractional and chemical purity from frozen or fresh animal byproducts, excluding its contamination with microbiological toxins with a maximum yield of hyaluronate of a wide molecular spectrum and the production of such related products as chondroitin sulfate, meal in a single technological cycle.

Granted: 2021-11-09
Abstract: FIELD: building materials. 
     SUBSTANCE: invention relates to the field of manufacture of building materials, namely, to the building and installation field in the area of fastening objects to walls, floors, ceilings. The term "anchor nail" relates to a product consisting of two main elements: an anchor and a spacer bar element. The anchor nail is used for performing fastening works and is applied for mounting objects to solid dense materials. The anchor nail fastener, consisting of an anchor and a spacer bar element, is made by a mould with a closure plane without additional moving elements, is made of a thermoplastic polymer in the form of a one-piece casting unit, ready for assembly and equipped with a spacer system for secure fixation. The anchor is made in the form of a cylinder with a collar by the upper base and with a slot along the entire axial plane of the cylinder. The slot divides the cylinder of the anchor into two equal parts interconnected by the lower base. The spacer bar element is made in the form of a nail with an upper head and is directed along the axial line of the anchor. The nail is located with the lower part thereof in the upper part of the slot of the anchor and is connected with the anchor by breakable bridges. The surfaces of the anchor nail can be made either smooth or with protrusions and recesses. The mated shapes of the slot and the surface of the spacer bar element are optimised for wedging the anchor, thereby providing self-centering and secure fixation of the anchor over the diameter of the hole in the wall or other surface. The method for installation and operation of the anchor nail fastener consists in the fact that the anchor nail is first inserted into a pre-drilled hole, then a force is applied to the end part of the nail head along the axis of the anchor using a hand tool for mounting work, the bridges are broken, and the anchor is expanded by the movement of the nail and securely fixated over the diameter of the hole in the wall or other surface. 
     EFFECT: manufacture of anchor nails suitable for mounting objects to solid dense materials.

Title: Superconducting resistance thermometer
Inventor: SHitov Sergej Vitalevich
IPC: G01K7/16
Filed: 2020-12-08
Granted: 2021-10-05
Abstract: FIELD: measuring equipment.  
     SUBSTANCE: invention can be used as a temperature sensor as part of cryogenic installations whose operating temperatures are below the critical temperature of a massive superconducting material used in a thermometer. According to the claimed solution, the temperature range of the superconducting transition of the film as a whole is expanded in comparison with the width of the superconducting transition of the massive superconductor from which the film is made. The principle of operation is based on the fact that in a film with a variable thickness, in the presence of the proximity effect, there is a temperature range within which a localized boundary (NS-boundary) occurs, dividing the electronic states into regions of the superconducting phase (R=0) and the normal phase (R≠0). Such a boundary changes its position with a change in the substrate temperature, as a result of which the total resistance of the film in the operating temperature range is different from zero and changes smoothly with a change in the substrate temperature. The calibration of such a thermometer is similar to the calibration of any other secondary thermometer of this temperature range.   
     EFFECT: fact that the sensor changes its resistance in a certain temperature range located below the critical temperature of the superconductor and amounting to several tens of percent of the critical temperature value.

Title: Verfahren zum Hydrieren von Kohle
IPC: C10G1/08

Granted: 1984-03-08
Abstract: Die Erfindung betrifft ein Verfahren zum Hydrieren von Kohle, bei dem die feingemahlene Kohle mit einem Anreiboel zu einem Brei verruehrt, der Kohlebrei auf Druck gepumpt, vorgewaermt und dann in einem Hydrierreaktor in Gegenwart von Wasserstoff der katalytisch beschleunigten Hydrierung unterzogen wird und bei dem das Hydrierprodukt in eine fluessige Feststoffhaltige und eine gasfoermige Fraktion zerlegt wird. Dadurch, dass eine aus der gasfoermigen Produktfraktion abgetrennte Kohlenwasserstoffraktion mit einem Siedebogen von etwa 280 Grad C und einem Siedeende von etwa 420 Grad C, im wesentlichen also ein Mittel- und Schweroel, dem Kohlebrei zugemischt wird, gelingt es, die Viskositaet des bereits auf Druck gempumpten Kohlebrei wesentlich zu erniedrigen. Hierdurch verbessert sich der Waermeaustausch des Kohlebreis mit den heissen Zerlegungsprodukten erheblich. Vor allem kann aber auch das Quillen der Kohle bei der Vorerwaermung und das damit verbundene unkontrollierbare Pulsieren, welches mit hohen Druckverlusten und grossem Materialverschleiss in den entsprechenden Waermeaustauschern verbunden ist, weitgehend abgebaut werden.                                                                                                                                                                                                                                                                                                                                                        ...U.S.W

IPC: G10L15/00
Filed: 1977-05-07
Granted: 1987-01-29
Abstract: For sound analysis, especially for speaker identification, a long-term spectrum is often formed from the recorded signal and compared to a long-term spectrum of a previously recorded signal. When the signal is, for example, received over telephone lines the transfer function thereof may distort the received signal to such an extent that identification is impossible. It is now proposed not to use the long-term spectrum for identification but rather its change, that is to say to accumulate the difference between two consecutive short-term spectra or the difference between such short-term spectrum and the long-term spectrum and to divide this accumulated value by the long-term spectrum in a Divider. Since the numerator and denominator each contain the frequency-weighting factor (aJ) of the telephone line transfer function, this factor is effectively cancelled out by virtue of the division operation performed in the Divider thereby eliminating the effect of the unknown transfer function. As a result the influence of the transfer function of the transmission path disappears almost completely.
