The outer sealing member is disposed to engage an outer corner of the rim of the neck of the bottle when the closure is threaded onto the bottle, and the inner sealing member is disposed to engage the top of the rim after engagement of the corner with the outer sealing member. The outer sealing member deflects outward slightly, and the inner sealing member deflects upwardly and inwardly. Movement of the top wall of the closure toward the rim is limited by a shoulder between the sealing members, so that when the closure is fully threaded onto the bottle, the inner sealing member is spaced from the inner surface of the top wall of the closure.

Filed: 1992-11-12
Abstract: A method and apparatus for supplying an inert gas under extreme pressure to a weldable air bag canister having a gas-charging opening in one end wall, and weld sealing the opening. The canister, and a composite welding head and weld ball supplying assembly, having a lower nose with a seal surrounding a ball dispensing opening therein, are relatively moved axially to seal off the opening in the canister end wall. Then, prior to pressurizing the assembly, an individual ball is presupplied through a passageway seal system to a ball delivery member inboard of the seals which axe provided in the welding head and weld ball supplying assembly.      Thereafter, the composite assembly is charged with gas under a heavy pressure measured in thousands of pounds per square inch, and a raiseable and lowerable welding electrode, carried by the assembly axially in alignment with the ball receiving chamber and ball dispensing opening, delivers welding current to melt collapse the ball to seal the opening. Finally, the electrode is moved back to retreated position and the assembly is depressurized.

Title: Apparatus and method for wetting and dissolving dry particles
Inventor: HSU SHENG H
IPC: B01F27/74
Filed: 1993-01-28
Abstract: ABSTRACT This invention is directed to an apparatus and method for wetting and dissolving finely divided dry particles, including hygroscopic particles such as coffee fines, in a liquid, including viscous liquids such as concentrated cof-fee liquor, in a manner in which foaming, the presence of wet lumps and liquor degradation  are minimized. The appa-ratus includes a dissolving tank containing at least one pair of counter-rotating drums partially submerged in a body of the dissolving liquid. The tank includes a liquid inlet and a discharge conduit which maintain a predeter-mined level of liquid in the tank.  A powder feeding device mounted above the tank discharges a falling curtain of par-ticles onto a thin layer of liquid on the surface of one of the drums in each counter rotating pair.  The partially wetted powder is carried into the nip between the counter-rotating drums to compress, knead and break up wet lumps of partially wetted powder formed on the surface of the drums, with the wetted powder being carried into and dissolved in the body of liquor.  Continued rotation of the drums car-ried any wet powder lumps which may remain in the liquor into the converging gap between the drum and a tangentially mounted solubilizing bar to abrade and disintegrate the lumps in the liquor body.  Any minor amounts of powder lumps which remain in the liquor are passed through a cy-lindrical filter having converging gaps formed by securing a plurality of wedges in close proximity to one another.          Any remaining powder lumps are compressed, sheared and dis-solved upon passage through the filter to provide coffee liquor having an increased solids content, which is free of undissolved particles and wet powder lumps.

IPC: C21B9/10
Filed: 1993-04-13
Abstract: ABSTRACT       AIR SEPARATION            Air is compressed in a compressor 4.  A minor air stream is taken from the compressor 4 and is cooled in a heat exchanger 12 by heat exchange with a pressurised stream of water.  The cooled minor air stream is separated in a plant 30 into oxygen and nitrogen.  Oxygen is supplied via a compressor 32 to a blast furnace 36 in which iron ore is reduced to iron and a low grade fuel gas is formed.  The fuel gas is compressed in compressor 40 and is moisturised in a gas-liquid contact column 18 with water supplied from the heat exchanger 12.  The moisturised fuel gas is supplied to a combustion chamber 6 and is burnt therein utilising the rest of the compressed air from the compressor 4.  The resulting combustion gases are expanded in an expander a which is employed in the generation of electrical power.

Title: Apparatus and method for aseptically reconstituting beverages
Inventor: HEATH HAROLD R
IPC: A23L2/42
Filed: 1992-03-18
Abstract: The invention provides a method and apparatus for reconstituting beverages wherein superheated reconstituting liquid and beverage concentrate are delivered into a mixing chamber having an adjustable volume, The mixing chamber is the volume (42) between two coaxially arranged tapered elements (43, 44) which are disposed one inside of the other. Final beverage product emanates from an aperture (48) in the tip of the ou-ter tapered element. At least one tapered element can be displaced in the longitudinal direction so that the volume of the mixing chamber decreases and approaches zero as the tapered elements are moved closer together. Thus, when the system is shut down the volume of the mixing chamber is allowed to approach zero so that very little product is susceptible to degradation in the mixing chamber due to prolonged exposure to high temperatures during a shutdown. The reduced volume mixing chamber may be flushed with reconstituting liquid. In addition, the temperature of the mixing chamber can be controlled during a shutdown by adjusting the temperature of water contained within the walls of the tapered elements.
