Abstract: A process for removing heat stable alkanolamine salts from an alkanolamine sorbent employed in gas conditioning for the removal of acid gases from a gas stream wherein the heat stable alkanolamine salts are formed during thermal regeneration of the alkanolamine sorbent.  In the process, the lean regenerated amine sorbent solution is fed to an electrochemical cell comprising a housing which is separated by an anion exchange membrane into an anode and a cathode compartment, wherein the anode compartment contains a platinum coated, platinized or iridium oxide coated anode and the cathode comprises an expanded metal metal plate cathode.  The anode compartment contains an aqueous anolyte solution of an alkali metal salt which is capable of reacting with the anions of the heat stable alkanolamine salts, and withdrawing from the cathode compartment a lean amine sorbent.  The process is an effective way to maintain the overall efficiency of the amine with respect to regeneration of the amine sorbent for reuse in the absorbing process and distinguishes from conventional processes in which the amine sorbent solution is transported to a caustic treater wherein the salts are decomposed to their respective amine and salt components.  Such processes are time consuming, not readily adaptable to field operation on site, and relatively expensive.

Abstract: ABSTRACT OF THE DISCLOSURE          An improved trap fitting assembly (F1, F2) which prevents the spread of fire and smoke through a floor (100,200) of a building is described.  The fitting uses a flammable coupling (10, 30) and a non-flammable sleeve (14, 32) inside the coupling with an extension (14b, 32b) from a lower most portion of the floor which is connected to a non-flammable J-pipe (16, 34).  In use the J-pipe contains water (101, 201) at a level (L-L) prevents the fire and smoke from going through the floor.  The trap fitting is preferably adapted for a floor drain outlet (11) or tub (203).

Abstract: In a telephone banking service, initial log-on (before service has identified the user) must use speaker-independent recognition (ie the speech recognizer 2 operates in accordance with a word template drawn from the population at large). Once the speaker is identified, the recognizer 2 employs a template specific to each individual speaker; this is much more accurate. The invention assists the log-on procedure by assigning each speaker a password consisting of a string of, for example, 5 digits which uniquely identify him, measuring the clarity with which the speaker recites each digit, compared to the standard template, and selecting his password from only those digits which he can clearly pronounce. The first digit may be used to indicate whether the speaker is male or female, and thereafter a respective "male" or "female" standard template may be employed.

Abstract: VERTICAL REACTION VESSEL                 Abstract of the Disclosure A method and apparatus for uniformly distributing fluid across the entire cross section of a reaction medium and for compensating for volumetric changes in the reaction medium utilizes a resilient membrane which cooperates with an adjacent  fluid manifold distribution chamber.   The combined operation of the manifold distribution chamber with the resilient membrane provides a low resistance to fluid flow in a direction transverse to fluid flow through the reaction medium and a higher resistance to fluid f low across the membrane in the direction of fluid flow through the reaction medium.  In this way, fluid is evenly distrib-uted across the cross section of the reaction medium prior to entering the reaction medium and after leaving the reaction medium.   The resilient membranes have reserve expansion  capabilities,  when  hydrated,  to  accommodate expansion in the reaction medium.  The resilient membranes are also sufficiently resilient to accommodate expansion of the reaction medium when necessary.

Abstract: In the method for manufacturing activated carbon from cellulosic material, the material is treated with a phosphoric compound like an ammonium phosphate compound which forms an ester with cellulose. The material is pyrolysed and activated in a suitable atmosphere and using a suitable temperature-time program. Activation is performed in a carbon dioxide atmosphere by a reduction reaction of carbon dioxide as the carbon dioxide gas flows past the material under treatment. As the cellulosic material, regenerated cellulose fibre like viscose fibre is used. Activation stage is continued at over 850  DEG C until yield of about 14-25 % is obtained whereby BET values of 1000-1600 m<2>/g are reached.
