Title: Apparecchio per il disinquinamento dei gas di scarico provenienti dai  motori a benzina,diesel,e dai processi industriali.
Inventor: CUBONI SALVATORE
Filed: 1992-07-30
Abstract: Il processo consiste, nel far passare, attraverso una tubazione, i gas di scarico provenienti dalla marmitta, attualmente esistente in tutte le autovetture ed automezzi, ovvero dalle ciminiere industriali, fino ad introdurli in un serbatoio di adeguata capacità, contenente del liquido, per circa la metà della sua capacità; all'interno del serbatoio, i gas vengono fatti passare attraverso un tronco di tubo dalla superficie forata ed attraverso la quale si immettono nella massa liquida alla quale cedono tutte le impurità che vanno a depositarsi sul fondo, mentre la parte areiforme fuoriesce, disinquinata, e, volendo anche con diverse profumazioni, all'esterno nell'ambiente.L'apparecchio è costituito da:- tubazione di convogliamento dei gas con in testa una valvola di ritegno:- serbatoio di forma parallelepipeda od altra, con grata frangiflusso, scarico di fondo e valvola di alimentazione del liquido;- tronco di tubo con la superficie forata:- tubazione di scarico nell'ambiente con innesto nella parte superiore del serbatoio e ripiegata verso il basso.IL PROCESSO SOPRADESCRITTO PUO' AVVENIRE A CALDO O A FREDDO E CON QUALSIASI LIQUIDO

Title: Method of making a fastening peg for aerated concrete
Inventor: TUMALSKI TADEUSZ
IPC: F16B15/04
Filed: 1992-11-27
Abstract: In order to fasten structural parts on a porous underlying surface such as, for example, gas concrete, a nail for gas concrete is formed from a half-round metal rod which is grooved transversely to the longitudinal axis. The points, projecting away from each other, of the nail are pushed through the splitting disc (7) and the nail is driven into the material. The transverse bar (6) of the splitting disc acts on the two shank halves of the nail with a lateral force which spreads out the nail in the form of a claw, independently of the effect of the underlying surface. In addition, the transverse grooves of the nail improve the load-bearing capacity of the connection in the gas concrete. <IMAGE>

Title: Method for extracting xenon
Inventor: HAHN ERICH
IPC: F25J3/04
Filed: 1999-05-05
Abstract: The invention relates to a method for extracting xenon and eventually also krypton from a liquid oxygen (LOX) charge, as it accrues in a cryogenic air separation system (LZA) during a rectification of the air, mostly as a bottom product of a low-pressure, column, namely with xenon (Xe), krypton (Kr) and hydrocarbons (CxHy) in a small concentration and approximately 99 mol % oxygen (O2). According to the inventive method, the LOX charge is fed to a first column, the oxygen of the LOX charge is extensively removed by stripping with an inert gas, and is extracted in the top gas, whereas the inert gas is withdrawn in the form of a liquid from the bottom of the first column with little O2 and nearly the total mass of CxHy, Kr, Xe. According to the invention, the liquid discharge is fed to a second column without prior catalytic and/or adsorptive removal of CxHy. A Kr fraction is extracted as top gas of the second column, and an Xe fraction is withdrawn from the bottom of the second column. The method can be used in a device for extracting Xe and/or Kr in an air separation system (LZA). The device can be arranged in a transportable container.
