  • Publication number: 20030167638
    Abstract: What is proposed is an electrically operated hair removing device, such as shaver, hair/beard clipper, epilation device or the like, having an operating system—connected to a housing—for clipping and/or plucking hair, which system has at least two operating elements which are movable relative to one another and at least one of which is driven, and having at least one illumination device for illuminating or transilluminating the operating system, at least one illumination device being integrated in at least one of the operating elements.

  • Patent number: 6224755
    Abstract: A coffee maker and a method of preparing coffee in which steam is applied to the coffee grinds prior to passing hot water through the coffee grinds. The coffee maker includes a controllable outlet valve disposed within a fluid path, between a water reservoir and a flow-through heater. In a first position, the outlet valve has a flow opening dimensioned sufficiently small that water exiting the outlet valve evaporates completely in the flow-through heater. In a second position, the outlet valve has a flow opening dimensioned sufficiently large that water exiting the outlet valve is heated in the flow-through heater without appreciable development of steam.

  • Patent number: 6189438
    Abstract: The invention is directed to a filtering device, a filter element therefor and a method of manufacturing the filter element (28) from filter paper. The filter element (28) has a receiving cavity (76) to be filled with extractable materials such as coffee grounds or tea leaves. Following contact with hot water, the extractable materials deliver extractive substances to the water, resulting in a brewed beverage that is drained from the filter element (28). During this process, the filter element (28) is held by the filter support (1) by way of a supporting member which includes a rim (39) formed on the filter element (28) and having a bearing surface (40), and a supporting surface (24) formed on the filter support (1). The rim (39) of the filter element (28) is reinforced mechanically by providing the filter paper with exposed pleats (42, 51, 52) which cooperate with corresponding elevations (115) and recesses (79) formed on the supporting surface (24) of the filter support (1).

  • Patent number: 6006655
    Abstract: The present invention relates to an electic coffee machine and a filter element (1) therefor. The coffee machine includes a filter element (1) for taking up ground coffee (12) that is supported by a filter housing. A brewing head (2) is provided above the filter element (1) and has one or a plurality of outlet openings (3) from which water (14) heated by an electric water heater flows into the element (1) in order to extract the coffee. According to the present invention, the filter element (1) includes on its outside top edge (9) an annular collar (10) which extends at an angle relative to the edge (9). The filter element (1) is made of filter paper. Disposed below the annular collar (9) is a securing device (28) which bears the filter element (1) and on which the filter element (1) is supported in a substantially cantilevered manner. In this way, the filter element and the coffee machine are easier to handle. In addition, brewing results are improved and the dripping time is reduced.

  • Patent number: 5752618
    Abstract: The invention is directed to a carafe (10) for carrying a beverage, with a vessel (12) formed in particular from glass and having at its opening an upper rim (26) upon which a plastic ring structure (28) is seated. Because the thermal expansion of plastics is about 20 times greater than that of glass, the seat of the plastic ring (28) on the vessel (12) may work loose due to the effect of changing temperatures to which the carafe (10) is exposed as when hot or cold beverages are filled in. In order to ensure a consistently firm seat also at varying temperatures, it is proposed in the invention that the plastic ring structure (28) be provided with inner (30, 36) and outer (38) detent means rearwardly engaging inner (20) and outer (24) undercuts of the vessel (12).
