Patent GB-2046696-A (GB)
Title: Filling and sealing valve bags
IPC: B65B1/18
Filed: 1980-02-21
Abstract: An apparatus for filling and sealing valve-type bags includes a clamp (34, Fig. 1) which holds the bag against a filling spout (31) while the bag is being filled causing temporary sealing between the upper portion of the bag valve and the upper portion of the filling spout. The clamp also pushes the bag from the spout after the bag has been filled. The filling spout, through which material is injected under pressure into the bag, includes an arcuate chamber (70) located about its lower half. Air is injected into this chamber at a higher pressure than that at which material is injected into the bag. The air injection results in a lower portion of the bag valve sealing against a lower portion of the filling spout, thereby in combination with the clamp temporarily sealing the bag to the spout. When the bag has been filled water is injected into the chamber (70) as the clamp pushes the bag from the filling spout. The water injection activates a water-soluble polymer sleeve (21) in the valve throat to permit adhesion of opposing surfaces of the polymer sleeve and hence permanent sealing of the bag. <IMAGE>

Title: Method of sustaining a heat consuming process
IPC: F02C6/10
Filed: 1979-03-27
Abstract: A method of operation is described for a heat consuming chemical process which employs a compressor/expansion turbine combination in which air is supplied from a compressor 4 to a catalyst regenerator 1 and waste gases pass to a hot-gas expander 3 where the amount of energy released to the gas going to the expander turbine 3 becomes insufficient to sustain operation of the process. The process may then be sustained by passing air from compressor 4 to burner 8, heating the air in the burner to such a temperature that when it is combined via line 9 with the hot gases in line 2 the temperature of the combined gas stream is sufficiently high to re- energise and sustain the process. <IMAGE>
