Abstract: In a pressure swing adsorption process for the production of nitrogen enriched product gas from air, when the process is halted during a pressure equalisation step, that is, with valves 5 and 6 open to permit the flow of gas from one vessel 16 to a second vessel 16', then the gas remaining in the vessels 16, 16' is exhausted to atmosphere by opening valve 14. 
     This results in rapid return to the required purity of nitrogen enriched product gas on start-up of the process. 
     Preferably, subsequent to opening valve 14, valve 15 is opened, thereby permitting nitrogen-rich product gas from reservoir 11 to flow through the vessels 16, 16', thereby purging said vessels with nitrogen enriched product gas.

Abstract: An apparatus for treating solids with a liquid at elevated or ambient temperatures comprises an assembly of vertical Pot (1) sealed by Lid (3) in which Pot (1) contains the liquid and horizontal low level stirring means (6) inducing a liquid vortex and contains disposed above stirring means (6) a horizontal peripheral appertured layer (9) offering minimum inferference with the vortex and contains vertical open cylinder (11) bottomed by central appertured layer (10), co-planar with layer (9), being liquid permeable but supporting solids impermeably. The vortex rises through layer (9) up internal vertical wall of Pot (1) and into diagonally opposite inlets (18) of horizontal tube (16) suspended internally from lid (3) above cylinder (11). Liquid downpours through exit (19) of tube (16) through solids in cylinder (11) and through layer (10) to re-enter the vortex. Layers (9) and (10), are predisposed above the unstirred level of the thermostatted liquid, hence at the cease of stirring, the total iquid fall back leaves the solids isolated from the liquid at the thermostatted temperature of the assembly.

Abstract: The telecopy device is intended for fast transmission of telecopies according to a redundancy-reducing code. It includes an encoding/decoding stage (CD), which includes a control unit (ST), a buffer store (ZS) and a microcomputer (MR). The control unit (ST) is constructed using a read-only memory control (FS) and determines during the transmission of a telecopy from image signals (B1) produced by a scanner (AB) just how two neighbouring lines relate in terms of their neighbouring position and emits corresponding line signals (L1) to the buffer store (ZS). A microcomputer (MR) which likewise has access to the buffer store (ZS), assigns code words (C) to the line signals (L2) in accordance with the known MRC code and emits these code words via a transmission unit (ME). Upon receiving a telecopy, the microcomputer (MR) assigns to the code words (C4) received the line signals (L3), which are converted by means of the control unit (ST) back into image signals (B4) and output to a printing unit (DR). A great many components in the encoding/decoding stage (CD) are used both during encoding and during decoding. <IMAGE>
