Title: A beverage package and a method of packaging a beverage containing gas in solution.
Inventor: FORAGE ALAN JAMES
IPC: B65D85/72
Filed: 1986-11-27
Abstract: A beverage package and a method of packaging a beverage having gas (preferably at least one of carbon dioxide and inert (nitrogen gases) in solution has a non-resealable container 1 within which is located a hollow pod 4 having a restricted aperture 7 in a side wall. The container is charged with the beverage 8 and sealed. Beverage from the main chamber of the container enters the pod 4 (shown at 8a) by way of the aperture 7 to provide headspaces 1a in the container and 4a in the pod 4. Gas within the headspaces 1a and 4a is at greater than atmospheric pressure. Preferably the beverage is drawn into the hollow pod by subjecting the package to a heating and cooling cycle. Upon opening the container 1 by draw ring/region 13, the headspace 1a is vented to atmosphere and the pressure differential resulting from the pressure in the pod headspace 4a causes gas/beverage to be ejected from the pod (by way of the aperture 7) into the beverage 8. Said ejection causes gas to be evolved from solution in the beverage in the main container chamber to form a head of froth on the beverage. The pod 4 is preferably formed by blow moulding and located as a press fit within the container 1 which latter is preferably a can, carton or bottle.

Title: Method for heat rate improvement in partial-arc steam turbine
Inventor: SILVESTRE GEORGE JOSEPH
IPC: F01D17/00
Filed: 1990-03-21
Abstract: Method for improving the heat rate of a steam turbine operated in a partial-arc mode includes sequential closing of control valves to establish a first arc of admission followed by a reduction of steam pressure to a predetermined level. Additional valves are closed to bring the admission arc to an optimum value and power reduction is thereafter affected by pressure reduction. In a further method, low power operation is achieved by reducing the arc of admission below optimum when steam pressure has been reduced to a minimum value.
