Abstract: 1286971 Heated bitumen tanks ZIMMERMANN & VONHOF KESSEL-BEHALTERUND APPARATEBAU KG 8 Aug 1969 39806/69 Heading E1G [Also in Division F4] In a storage vessel 1 containing a thermoplastic material to be heated, e.g. bitumen, a heating unit 2 comprising a tubular coil 6 mounted within a housing 3 provided with an insulating jacket 7 projects into and is secured to the vessel 1. A heating medium namely oil, passing through the coil 6 is heated by hot gases from an oil fired burner 4 connected to the outer end of the housing 3. Exhaust gases leave the unit 2 through a chimney 5. The thus heated oil is passed from the coil 6 through a pipe system (not shown) running along the outside surface of the storage vessel. The bitumen in the storage vessel is thereby heated indirectly by heat from the hot oil. The pipe system can alternatively be arranged within the vessel, e.g. on the outside of the insulated housing 3. In an alternative embodiment (Fig. 2 not shown) the bitumen vessel is heated by passing it into the heating unit (12) where a heat exchanges with the hot oil in the tubular coil (16), the heated bitumen then being returned to the storage vessel through suitable piping. In this case the hot oil flowing through the coil is heated externally of the unit (12), the burner of Fig. 1 being omitted.

Title: Sterilisation
IPC: A61L2/20
Filed: 1977-09-29
Abstract: A web (1) of packaging material runs through two chambers (3, 4) from a roller (2) and, after being deflected twice by guide rollers (5), is shaped into a tube (6), filled via a filling pipe (7) and sealed to form packages (9, 10). The air, conveyed by a compressor (11) and dewatered in a water separator (13), is fed via a regulating valve (15) to a heating element (17) and provided with sterilising agent by means of an ultrasonic nozzle (19), whereupon the mist formed is mixed with hot air in a mixing chamber (18). The steam thus evolved comes into contact with the packaging material in the chamber (3), is cooled thereon, condenses and flows out partially through an outflow pipe (23). On passage through the second chamber (4), the remainder of the sterilising agent is removed from the web (1). The method permits exact control of the sterilising process without addition of stabilisers and wetting agents. Furthermore, the consumption of sterilising agent is very low. Disposable packages sterilised in this way are used for packaging liquid foodstuffs, e.g. milk. <IMAGE>
