Patent HU-189005-B (HU)
Inventor: KISS ISTVAN
IPC: F24F3/16
Filed: 1983-12-02
Abstract: A találmány tárgya: kondenzációs szekrény, vegyigyárak, vegyi üzemek laboratóriumaiban felállított vegyifülkékben keletkező és az emberi szervezetre káros gőz- és gőznemü anyagok, valamint mechanikus szennyeződés megkötésére. A találmány szerinti berendezés a vegyifülkéhez közvetlen csatlakozással egybeépített olyan zárt tér, amelynek legfelső pontján van kialakítva az elszívócső, amelyen keresztül önmagában ismert elszívóberendezés révén a levegőt a külső környezetbe vezetjük. A kondenzációs szekrénybe vízfüggönyt létesítő csövek torkollnak, amelyek a felfelé áramló levegőből kicsapódott káros gőzöket oldó vizet szolgáltatják, amely a kondenzátumot technológiai csatornába vezeti, A kicsapódást a kondenzációs szekrényen belül kialakított, terelőlemezként is szolgáló további zárt téren belül áramló hűtőlevegő által lehűtött lemezek segítik elő. A felfelé áramló szennyezett levegő a szívócsőbe már megtisztítva kerül és így a környezetet nem szenynyezi. (2. ábra.) 3-3  2,-Áb ni -1-

Katalysatoren utgjøres av et salt av et metall fra. gruppene IB, 2B eller VIII i det periodiske system, opplost eller dispergert i reaksjons-blandingen..Det er funnet at hydrogenet ikke forstyrrer reaksjonen, slik at en hydrogenanriket gassblanding (syntesegass) trekkes ut fra reaktoren. Det er derfor spesielt fordelaktig at prosessen samtidig fremstiller dimetylkarbonat og hydrogenanriket syntesegass.

Abstract: Reaction products of hydrogen cyanide are prepared by a process in which hydrogen cyanide prepared in a conventional manner by pyrolysis at from 250 DEG  to 650 DEG  C. over a solid under from 5 to 200 mbar is cooled to a temperature of from 200 DEG  to -10 DEG  C. together with the other pyrolysis products, the hydrogen cyanide is then fed to a chemisorption reaction with a base or with a carbonyl compound, and the reaction products of hydrogen cyanide which are formed therein are removed from the system and brought to atmospheric pressure. In this process, the handling of large amounts of hydrogen cyanide is avoided.

Abstract: A two-position annulus pressure responsive valve is used for well testing or treatment by running it into a wellbore with the valve in a first valve position (eg. open), increasing the wellbore pressure without cycling the valve to its second valve position, decreasing the pressure and cycling the valve to its second valve position (eg. closed) in response to said reduction in pressure. In the method, the string may be automatically filled, a packer may be pressure tested without cycling the valve, and fluids may be spotted into the testing string, displacing wellbore fluids from the bottom of the testing string, prior to running the test.

[Also in Division C3] Compounds capable of coupling with diazonium salts (e.g. α- or #- naphthol) can be detected in a liquid, which may contain such a coupling compound, by adding to the liquid a water-insoluble polymeric colour developer which contains aromatic diazonium salt groups attached to a cation exchange resin by means of amide linkages (see Division C3), and observing any colour development due to diazo coupling. For test use, the polymeric colour developer can be coated on, or incorporated in, a carrier material, e.g. it can be coated on filter paper to provide sheets containing colourdevelopable zones, or it can be mixed with cellulosic fibres in aqueous medium in order to prepare paper strips or discs containing colour-developing material; also, the polymeric developer can be incorporated into tablets. The colour developer can also be used in the detection of systems, e.g. enzymatic systems, which can be made to liberate coupling compounds, by treatment with a coupling compound precursor substrate, e.g. α- or #- naphthyl phosphate. Thus, in Examples, the developers are used to investigate phosphatase activity in suspect serum or in milk.
