Title: Sleeve joint externally threaded at its ends - in which elastic seal ring is arranged between elongated rings and abutment surface
Inventor: BONISSONE GIANCARLO
IPC: F16L19/065
Filed: 1977-08-06
Abstract: A pipe coupling consists of a sleeve (1) with threaded ends for tightening nuts (5,6). Grooves for sealing rings (20) are formed conjointly by conical abutment surfaces (17) on the sleeve and similar surfaces on loose annular member (18,19). Split wedge section gripping rings (9,10) are compressed by the nuts radially onto the pipes (11,12) and axially onto the annular members (18,19). This transmits compression to the sealing rings (20) which causes them to exert sealing pressure on the pipes. Pref. for plastic piping systems, or could be used in metal systems. Relatively large tolerance in pipe size can be accepted.

Title: Transport of sub-bituminous coal through pipes - as aq. slurry, after drying to low moisture content
Inventor: SEITZER WALTER HAROLD
IPC: C10L5/00
Filed: 1978-04-27
Abstract: Sub-bituminous or lignitic coal is transported through pipes as an aq. slurry, after drying to reduce the moisture content to 0-10%. Method is esp. applied to Bell Ayre Wyoming coal or Glenharold lignite. Drying is suitably carried out in a fluidised bed or rotary over heated with combustion gases. Re- absorption of water by the coal is prevented, apparently due to irreversible changes in the structure, and the carrying capacity of the pipe for coal is increased by pre-drying.

Title: Dust filter separator - with backflushing control unit closing clean gas duct valve and producing compressed air pulses in filter bags
Inventor: ROTHE GUENTER DIPL ING
IPC: B01D46/00

Title: Water demineralisation process - using ion exchange resin particles contg. weak acidic gps. and carbonate type weak basic gps.
Inventor: SHIMIZU HIROSHI
IPC: B01J49/40
Filed: 1978-09-01
Abstract: An ion-exchange desalting method uses ion-exchange resin particles contg. both free acid type weak acidic gp. and carbonate type weak basic gp. in the same particle. The particles are contacted with aq. soln. contg. salt of strong acid to effect desalting. The particles having weak acidic gp. in salt type and the weak basic gp. converted into strong acid salt type are heated to convert them into free acid type and free base type respectively, then contacted with carbonic acid to convert the weak basic gp. part into carbonate type. The regenerated resin particles are then reused. The desalting capacity per unit amt. of ion-exchange resin particles is higher and the salt concn. of the treated desalted water is lower than by using known heat regeneration process desalting methods.
