  • Patent number: 7465330
    Abstract: A filter assembly has an annular outer wall with a channel for receiving a layer of adhesive and a center ring within the outer wall. A filter media having a plurality of pleats in a closed loop is bonded with adhesive to the outer wall. The assembly is made by rotating the outer wall in a jig and applying a layer of adhesive within the channel. The filter media is positioning the within the outer wall, rotated and allowed to move along a radial path until its outer perimeter contacts the adhesive coated outer wall inner perimeter. The ring is positioned adjacent the filter media inner perimeter.

  • Patent number: 7032502
    Abstract: A coffee maker includes a water reservoir, an in-line water heater, a brew basket for receiving coffee grinds, and a water passage between the reservoir and the brew basket. The passage passes through the in-line water heater for delivering heated water to the brew basket. A a bi-directional valve disposed in the water passage between the water reservoir and the in-line water heater to permit substantially unrestricted flow in a first direction and restricted flow in a second direction. A controller can be provided for altering the valve between an unrestricted bi-directional mode and a unidirectional mode.

  • Patent number: 6129007
    Abstract: An electric automatic pop-up toaster has a carriage and a pivotably connected manually operative arm for moving the carriage to a lowermost position for toasting in well-known manner. At the beginning of each toasting cycle, the arm is horizontal and a latching plate is magnetically held down to hold the arm and the carriage in a lowermost position. The arm presses against a wire spring to hold closed a power switch (not shown) that supplies power to heating elements of the toaster. The latching plate is (magnetically) released at the end of each toasting cycle by a timer. This allows the carriage to move upwards to pop-up toasted bread in a usual way. However should the carriage fail to move upwards when the latching plate is released, the arm is pivoted by a spring and tilted to the position shown in the Figure. The wire is therefore released and enters a slot in a bracket mounted to the carriage. The switch opens and remains open to prevent power being re-instated to the heating elements.
