Abstract: An electrical beverage brewer (10) having a controller (26) responsive to a start switch (72) to operate a brew cycle by dispensing hot water from a tank (42) to beverage ingredient within a brew basket (38) through a bent tube (78) mounted to the water tank (42) for rotation about an axis aligned with an external horizontal rotary section (90) of the bent tube (78) between a closed position in which an inlet (80) of a swinging tubular section (79) is in a relatively elevated, closed position and an open position at a lower elevation relative to the closed position.

Abstract: An airpot beverage dispenser (10) having a composite dispense tube (40) with an exterior outlet (44) adjacent a top of a hollow body (20) and an interior inlet (110) located adjacent a bottom (16) for passing beverage (36) from adjacent the bottom (16) to the outlet when the interior of the hollow body (20) is pressurized has a brew-through assembly with a cover body (24) for substantially closing the open top (18) except for a centrally located brew-through passageway (95) substantially smaller than the open top (18) and extending between an upwardly facing exterior brew-through inlet (30) and an interior outlet (102) that passes through a central passageway extending through a double-walled bellows (74) or extends past a plurality of bellows (FIG. 16, 114) that are laterally spaced from the passageway has an electronic display (48) for indicating a plurality of levels of the beverage (36) within the hollow body and a resistive (FIGS. 11-14) or capacitive (FIG.

Abstract: A lightweight cast acoustical material requiring less drying time and energy is obtained by lightly cooking an aqueous slurry of starch, cooling it to about less than 140.degree. F., whipping air into it, adding granulated mineral wool with thorough mixing to form a foam, casting the resultant wet foamed pulp into a form and drying the formed pulp to an acoustical product. The web pulp has an about 40 weight % reduction in water content, resulting in considerable savings in drying time and energy.
