Filed: 1988-10-31
Granted: 1993-04-13
Abstract: ABSTRACT     The present invention provides a novel train and track which can  be  used  in  an  automated,  tracked  sortation  system which  is  capable  of  sorting  and  transporting  high  volumes ofgoods efficiently and which gives flexible system design, easy set-up,  easy  servicing  with  minimum  down  time,  centralized control and a minimum of wiring complexity.  The train includes "smart" cars and a locomotive for pulling the cars around the track.  The trains are loaded with goods to be sorted and given destination  addresses  for  the  goods  at  a  loading  or  master station.   Once  a  train  has  left  the  master  station,  all functions including keeping track of position,  regulating speed and dumping cars are to be controlled by a microprocessor placed aboard each locomotive   This "smart" design allows the track to be very simple as it need only provide a path and lower supply for the trains to run on and the train can wait at the loading station until it has a full or partial load to deliver.  Power feed lines are provided associated with the track to power the locomotive,  and  passive  destination  or  slave  stations  are positioned about the track to receive sorted goods.

Title: Method for operating a melt-down gasifier and melt-down gasifier for the implementation of said method
Inventor: VULETIC BOGDAN
IPC: C21B13/14
Filed: 1988-12-09
Granted: 1992-12-01
Abstract: Method for operating a melt-down gasifier and melt-down gasifier for the implementation of said method Described is a method for operating a melt-down gasifier (4) in which iron-ore-containg charge materials or iron sponge obtained from same by direct reduction are smelted due to the addition of carbon carriers and blowing an oxygen-con-taining gas through oxygen nozzles (6) into a fluidized bed created by same, and are (further) reduced to make liquid pig iron or steel starting material. On failure or reduction of the oxygen supply below a predetermined quantity and on failure of the water cooling system of the oxygen nozzles, the still present oxygen supply is cut-off and an inert gas is fed into the melt-down gasifier through the said oxygen nozzles instead, for protecting said oxygen nozzles. Thus, liquid fluidized bed matter is prevented from  penetrating into the oxygen nozzles and to solidify in same. In the case of failure of the water cooling system of the oxygen nozzles, the inert gas serves also at the same time as cooling medium.          (Fig. 1)

Abstract: A  method  and  apparatus  for  the  separation  of  air  by pressure  swing  adsorption  utilizing  two  beds  of  adsorbent material which are operated out of phase, thereby providing a more or less continuous flow of product oxygen with  reduced argon  content.   A  first  adsorbent  bed  comprises  a carbon molecular  sieve  which  adsorbs  oxygen  more  rapidly  then nitrogen. The adsorbed oxygen is desorbed from the first bed and flows to a second bed, comprising a zeolite molecular sieve that  adsorbs   nitrogen  preferentially  to  oxygen,   thereby producing   product   oxygen   as   the   non-adsorbed   gas. Alternatively,  the  second  bed  comprises  a  carbon  molecular sieve,  and the  adsorbed  oxygen  is  desorbed  as  the  oxygen product gas.
