Abstract: A method of brewing a beverage using a beverage maker having a brew container, a first cylindrical section having a first diameter and a second section attached to the first cylindrical section having a portion with a second greater diameter; a liquid reservoir; a liquid delivery system to deliver the liquid to the brew container; a plunger assembly having a filter portion to filter the substance to produce the beverage from the liquid and a gasket to form a seal between the plunger assembly and an inner wall of the brew container in the first cylindrical section. As the plunger assembly is raised through the liquid a vacuum is formed between the plunger assembly and the bottom of the brew container and the filter traps and separates the substance to produce the beverage from the beverage.

Abstract: A device for delivering a liquid heated to a desired temperature under pressure in a microwave oven comprises a first chamber adapted to receive and hold a first volume of a liquid, a second chamber adapted to receive and hold a second volume of the liquid, a vapor flow path from the first chamber to the second chamber, and a liquid/vapor flow path from the second chamber to a destination outside of the second chamber. When the liquid in the first chamber reaches its boiling point and at least partially turns into a gas, at least a portion of the gas flows through the vapor flow path from the first chamber into the second chamber, thereby increasing a pressure in the second chamber. The increased pressure in the second chamber forces the liquid in the second chamber through the liquid/vapor flow path and out of the second chamber.

Abstract: A vacuum coffee maker has a starved electric heating arrangement having a solid body providing a reservoir. The chamber is covered by a circular lid that prevents flow of steam directly vertically up a tube from the chamber. At the end of a normal heating cycle, the temperature of the body rises rapidly and power supplied to a heating element is automatically turned off under the control of a thermostat. The heating arrangement is used without alteration (e.g. to the setting of the thermostat) to keep-warm hot coffee in a lower container after the end of the normal heating coffee-making cycle. The effect of having the lid is that during a keep-warm function, the reservoir is generally starved of liquid because any liquid entering the reservoir is immediately evaporated and this restricts flow of more liquid into the reservoir and hence starves the reservoir.

Abstract: A tea making machine wherein the bottom wall of an upper vessel can be used to seal the open top of a lower vessel which contains a supply of water. The upper vessel contains a supply of tea leaves and its bottom wall has an upright tubular portion for a riser with an open upper end in the upper vessel and an open lower end in the lower vessel. The riser is adjustable so that its lower end can be moved to any one of a number of different levels above the bottom of the lower vessel. When the supply of water in the lower vessel is heated, the pressure in the lower vessel rises and boiling water is compelled to flow up the riser and into the upper vessel where it contacts the tea leaves. When the level of the supply of water in the lower vessel descends below the lower end of the riser, such water must be evaporated in order to rise into the upper vessel. The interval which elapses for evaporation determines the steeping time in the upper vessel.
