Abstract: A hollow fibre separatory module comprises six separate hollow fibre bundles, four of which (12, 14, 18, 19) are shown, in a single pressure shell (10, 11). There are two fluid feeds (32, 86), two concentrate outlets (34, 88) and six separate permeate outlets, four of which (36, 40, 90,92) are shown. For reasons governed mainly by the lengths of the inidividual fibres in the bundles, the overall size of the individual bundles is limited. In the past separatory modules have consisted of a single bundle of fibres in its own individual pressure shell. Such modules have such a small output that they are largely only useful for experimental work. The multi-bundle module in accordance with the invention has much greater commercial usefulness.

Inventor: WINTENBERGER MICHEL-GEORGES
IPC: B01D9/02
Filed: 1983-03-29
Abstract: The present invention relates to a process for purifying metals, such as aluminum, by segregation, wherein, by controlled cooling in the upper part of a volume of liquid metal to be purified, which is contained in a crucible and disposed in a furnace, small crystals are caused to form, the crystals falling towards the bottom of the container under the force of gravity. The small crystals are compacted so as to cause the formation of a compact layer of large purified crystals. This process is distinguished from the known processes in that, to enhance the purification effect, the thermal flux is so adjusted as to completely and progressively re-melt the lower part of the mass of large crystals which are formed, with the re-melting action being propagated upwardly so as permanently to maintain a layer of large crystals which separates the re-melted liquid entirely disposed in the lower part from the remaining mother liquor. That process makes it possible to attain extremely high levels of purification, in relation to very high fractions of the initial mass of aluminum which is to be purified. The process can be applied to metals such as aluminum, lead, zinc, magnesium and silicon containing eutectic impurities in hypoeutectic amounts.

Abstract: A process for the operation of a circulating, fluidized bed reactor is described, by which a solid particle material comprising a solid reactant material, in particular carbonaceous fuel, is introduced into the lower part of the reactor and is formed to a fast bed by means of a fluidization gas containing a gaseous reactant material, in particular oxygen, introduced into the reactor bottom, while nonreacted particles are removed from the reactor top and recirculated to the bed. 
<??>By removing a predetermined fraction of the solid particle material being present in the reactor from at least one site positioned below the reactor top, subjecting it to thermal treatment and recirculating it to at least one other, lower positioned site of the bed, enhanced possibilities for process optimalization are achieved. 
<??>Furthermore a fluidized bed reactor is described comprising a vertical reactor chamber (1), a first inlet (9) in the lower part (2) of the reactor chamber for introduction of solid particle material, and a second inlet (22) in the bottom of the reactor chamber for introduction of fluidization gas, and an outlet conduit (28) in the upper part (4) of the reactor chamber for removal of reactor material.

Abstract: INTEGRATED DATA LINK CONTROLLER WITH      AUTONOMOUS LOGICAL ELEMENTS            ABSTRACT OF THE DISCLOSURE      A  single  chip  integrated  data  link  control  (IDLC) device provides full duplex data throughput and versatile protocol  adaptation  between  variably  configured  time channels on a high speed TDM digital link (e.g. T-1 or T-3 line) and a host data processing system. The device handles multiple  channels  of  mixed  voice  and  data  traffic concurrently, and thereby is suited for use in primary rate ISDN  (Integrated  Services  Digital  Network)  applications. Synchronous  and  asynchronous   sections  in  the  device respectively interface with the network and host system. Special purpose autonomous logic elements in the synchronous section form plural stage receive and transmit processing pipelines  between the network and host  interfaces.  Such pipelines perform OSI Layer 2 processing tasks on data in HDLC channels. Each autonomous element comprises one or more state  machine  circuits  having  functional  autonomy  and reduced  time  dependence  relative  to  other  elements.  A "resource manager"  element  (RSM)  and time  swap  (TS)  RAM memory  operate  to  dynamically  swap  states  of  pipeline elements  in  synchronism with  channel  time  slots  at  the network interface, whereby the pipeline stages operate as data buffering stages which perform multiple tasks during any slot. The device contains integrated memory queues in which   communication   data   and   channel   event   status information   are   stacked   for   asynchronous   transfer. Capacities  and  modes  of  operation  of  these  queues  are selected to minimize effects on chip size, throughput and cost, while minimizing critical time dependencies between the device and host system. Device elements provide first and  second  non-interfering  information  transfer  paths between the device and host system;  one for exchanges of control/status information between the device and host, and the   other   for   direct   memory   access   transfers   of communication data between the device and an external memory associated with the host.
