Patent HU-209467-B (HU)
Title: Method of making metal matrix composite based on aluminium
Inventor: AGHAJANIAN MICHAEL KEVORK
IPC: C22C1/10
Filed: 1989-01-16
Abstract: A net shaped ceramic-reinforced aluminum matrix composite is formed by forming a permeable mass of ceramic material (10) with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy (20) with the permeable mass of ceramic material (10) in the presence of a gas comprising from about 10 to 100 % nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy (20) spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy (20) can be placed adjacent to a permeable bedding of ceramic material (10) having a barrier, and brought to the molten state, preferably to at least about 700 DEG C, in order to form the net shape aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.

Title: Process for the thermally regenerative cleaning of gases which contain organic and/or inorganic carbon compounds as well as SO2 and SO3, and installation for carrying out the process
Inventor: SAMHABER FRIEDRICH DIPL ING DR
IPC: F23J15/02
Filed: 1994-03-01
Granted: 1995-09-25
Abstract: In the process, the gas stream which is to be cleaned is heated by heat exchange and by energy being supplied, in the process oxidizable pollutants are removed, and then the gas stream is cooled by heat exchange. To ensure that both the combustible pollutants and SO2/SO3 are thermally cleaned out of off-gases while avoiding corrosion problems, the gas stream, after the supply of energy, the oxidation of the pollutants and cooling, is sucked out, the SO2 fraction is catalytically oxidized, then the SO3 fraction is separated off and the gas which has been cleaned in this way is cooled further by heat exchange. The installation for carrying out the process comprises a first regenerator tower with heat-accumulator bodies for heating the gas stream which is to be cleaned, an adjoining device for supplying additional energy, a second regenerator tower which adjoins the device for supplying additional energy and has heat-accumulator bodies and devices for reversing the gas flow through the regenerator towers, as well as devices, which are arranged downstream of the device for heating the gas stream, as seen in the prevailing direction of flow of the gas, for extracting the gas from each of the regenerator towers, an SOx catalyst and an SO3 adsorption installation, preferably a dry adsorption installation. <IMAGE>

Abstract: A találmány szerinti rakfelület-rögzítő szerkezet működő eleme négy darab, külső részén lejtős felületű horog, amelyek rugó ellenében kenhető csapágyban ívben elfordíthatok. A horgokat rugók tartják zárt alaphelyzetben úgy, hogy azok a billenő csapok alá akadva kizárják a rakfelület véletlen felbillentését. Szándékos billentés esetén az egyik oldalon közös tengelyen lévő két horgot egy kézi karral lehet félrebilIcntcni cs ott kiakaszlással rögzíteni, Billcntcs közben a kiakaszlás megszűnik és a horgokat a rugók alaphelyzetbe zárják. A horgok a vezetőfülkéből távvezérléssel is félrebillenthetők és nyitott helyzetben tarthatók elektromos, illetve pneumatikus eszközökkel. A rakfelület visszabillenése közben az alaphelyzetben lévő horgok ferde felületeivel érintkeznek a billenő csapok és félrebillentik azokat, majd a rugók ismét bezárják őket, ha a rakfelület visszafekszik az alvázra. A kocsi homlokfalán mutatók jelzik a kétoldali csapok zárt, vagy nyitott helyzetét.  -1-

IPC: A61B/
Filed: 1990-03-27
Granted: 1993-12-27
Abstract: This device processes the information taken from blood contained in a sedimeter and calculates the buoyancy of the suspensions and the decrease over time (hourly equation), as well as calculates the breakdown of the bonds in the blood and analyses the pathology that is the cause. The equipment, with the Cartesian coordinates (or other coordinates), has the cinematic trace of the suspension decreasing and determining the first and second time in respect to the time present in the coordinates even the velocity diagrams and the acceleration of the suspensions.The equipment, using a mathematical method that is part of the calculation program supplied, writes the equations of the falling suspensions until the greater order that requests a more in-depth analysis of the blood. For other graphic and analytical processing considering the units mass the device eliminates the time parameters from the diagram already produced and using other symbols prints the diagrams on the amount of instant motion of the suspension, of the degradation of the energy of the blood and the falling power and in these diagrams the band of the pathology of the organism is limited having calculated the breakdown of the bonds in the blood and analyzed the pathology that caused it. The experiments on the blood and on the irradiated blood took place at the Laboratory of the "Umberto I" General Regional Hospital in Ancona.
