To enhance extraction and dissolution of soluble components of a solid material in water to make a beverage, an appliance comprises a serving chamber (10), a pressure regulating system, a filter assembly (12), a brewing chamber (11), a liquid passageway and a controller (67) that controls the pressure regulating system to alternately de-pressurize and pressurize the brewing chamber (11) is provided. The appliance further comprises a foam filter (39) to reduce the amount of foam in the beverage.
A personal vaporizer (10) comprising: a housing (21) enclosing an air passage (27); a reservoir (28)disposed within the housing (21) for holding a liquid; a vaporizer (29) comprising a heating element (41) embedded in a body of porous material permeable to the liquid, the body of porous material having an inner surface (46) and an opposing outer surface (35), the inner surface (46) bounding at least a portion of the air passage; a bulkhead (30) that closes an axial end of the reservoir (28); a liquid pathway through the bulkhead (30) connecting the reservoir (28) to the outer surface (35) of the body of porous material; a flow control device in the liquid pathway for regulating flow of the liquid. The personal vaporizer (10) can prevent liquid leakage and accidental suction of liquid into a user's mouth.
To enhance extraction and dissolution of soluble components of a solid material in water to make a beverage, an appliance comprises a pressure chamber, a source of pressurized air, a venting device, a filter assembly, a filter chamber and a controller that controls the supply of pressurized air from the source to the pressure chamber is provided.
A universal mouthpiece cover for e-cigarettes includes: a sleeve(10) tapered longitudinally, at least one peripheral weakened section in the external surface(17) of the sleeve(10) permitting the sleeve(10) to be manually torn apart transversely.
An appliance for producing frozen food products, such as ice cream or slush drinks, includes a cooling cylinder connected in a refrigeration circuit, the cooling cylinder including a thermally-conductive cylinder wall and end cap closing the distal end of the cylinder wall, the cylinder wall and end cap separating refrigerant on one side from product to be frozen on the other side. A divider member disposed adjacent the cylinder wall forms contiguous evaporator compartments spaced apart axially. Restrictor passages in the divider member permit communication between contiguous compartments and refrigerant first enters the first-cooled evaporator compartment at one of the axial ends and flows in series between the evaporator compartments. For fast, efficient freezing of small batches, the product to be frozen is either driven by the auger, or drains, toward the first-cooled evaporator compartment.
