Title: Counterpressured liquid transfer apparatus and variable control therefor
IPC: B67C3/06
Filed: 1965-07-28
Abstract: 1,101,080. Bottling. MOJONNIER BROS. CO. 28 July, 1965 [29 July, 1964], No. 32303/65. Heading B8T. [Also in Division G3] Carbonated beverage is produced at a first pressure in a tank 10 and passes to a bottle filling machine 24 operating at a second pressure via a device 50 that raises or lowers the pressure of the beverage from the first pressure to the second pressure. The tank 10 has water, syrup and gas inlets 12, 14, 16 respectively and an outlet pipe 22 communicating via a pump 80, valve 62 and pipe 54 with the rotating pipe 26 of the filling machine. The latter includes a rotating annular filler bowl 30 the liquid level in which is controlled by float operated valves 42, 46. The valve 62 is controlled by a pilot valve 60 which is responsive to the liquid level in a tank 52 as measured by a float 56, the tank 52 communicating with pipe 54 and being maintained at a pressure equal to the operating pressure of the filling machine by a gas supply admitted to the tank via a pressure regulator 70. In operation, and assuming that the tank 10 is maintained at 60 p.s.i. whereas the filling machine is required to operate at 40 p.s.i., beverage flows from tank 10 into tank 52 until the float 56 causes valve 62 to close. Tank 52 is maintained at 40 p.s.i. and when the level in the filler bowl drops vent valve 42 is opened to lower the pressure in the bowl to allow beverage to be admitted from tank 52. As the level in the bowl rises, valve 42 is closed and valve 46 is opened to raise the pressure in the bowl to 40 p.s.i. to stop flow from tank 52. If it is desired to operate the filling machine at a pressure higher than that in tank 10, e.g. 90 p.s.i., then tank 52 is maintained at 90 p.s.i. and pump 80 is used to raise the pressure of beverage flowing from tank 10 to 100 p.s.i.
