  • Patent number: 7414590
    Abstract: An antenna device has a sheet-shaped support which is folded along various fold-lines. The support includes a first support plane adjacent to one of the fold-lines and a second support place adjacent to the same fold-line. The first and second support places have first and second antenna structures, respectively, each arranged for receiving or emitting electro-magnetic radiation. The second support plane is positioned at an angle with respect to the first support plane. The second antenna structure is sensitive to electro-magnetic radiation which differs in, e.g., polarization from that of electro-magnetic radiation to which the first antenna structure is sensitive.

  • Publication number: 20060273974
    Abstract: An antenna device (1, 1?, 1?) comprising: a sheet-shaped support (2) which is folded along a fold-line (3-8, 80-83). The support (2) includes a first support (10-13) plane adjacent to said fold-lines (3-8, 80-83) and a second support plane (10-13) adjacent to a of said fold-lines (3-8, 80-83). The first support plane (10-13) has a first antenna structure (100) arranged for receiving or emitting electro-magnetic radiation and the second support plane (10-13) has a second antenna structure (100) arranged for receiving or emitting electro-magnetic radiation. The second support plane is (10-13) positioned at an angle with respect to the first support plane (10-13). The second antenna structure (100) is sensitive to electro-magnetic radiation which differs in a property to the electro-magnetic radiation to which said first antenna structure (100) is sensitive.

  • Publication number: 20050241492
    Abstract: A deep fat fryer has a control system (11) connected to a temperature sensor circuit (6) and to a heater control (13) for thermostatically activating a heating element (2) in response to a temperature signal from a temperature sensor circuit (6) representing a temperature at or below a lower limit value and deactivating the heating element (2) in response to a temperature signal representing a temperature at or above an upper limit value. The control system (11) is further adapted for, if the heating element (2) is active, generating the food lowering command signal in response to a temperature signal from the temperature sensor circuit (6) representing a predetermined sensed temperature below the upper limit value.

  • Patent number: 6571689
    Abstract: An apparatus for deep-frying food, comprising a vapour discharge channel (6) communicating with an inner space (3) and extending from an upper portion of said inner space. A cooling surface (7), which is cooled in use, is provided for cooling vapours. Condensate that has deposited precipitated on the cooling surface (7) can be collected in a collecting reservoir (13), into which the vapour discharge channel (6) opens. Fat contained in vapour being discharged deposits in a fat deposition area (14) outside the cooling surface (7). Since at least a portion of the fat deposition area (14) communicates with the collecting reservoir (13) for carrying fat that has deposited in the fat deposition area to the collecting reservoir along a path remote from the cooling surface (7), and/or since the vapour discharge channel (6) extends along a straight trajectory, the deposition of fat is made to occur in an area from which it can easily be removed.

  • Patent number: 6546848
    Abstract: An apparatus for deep-frying food, including a window (22) of a transparent material which takes up at least a portion of a cover (5; 105; 205) and which extends at least partially at an angle or vertically. A vapor discharge channel (6) communicates with the inner space (3) of the pan. A cooling surface (7) is provided for cooling vapor, which cooling surface communicates with the inner space (3) via the vapor discharge channel (6). A storage reservoir (13) is used for storing condensate that has precipitated on the cooling surface (7), and a collecting gutter (21; 121; 221) serves for collecting condensate that has precipitated on the window (22). The collecting gutter (21; 121; 221) extends along a bottom end of the window (22) and includes a drain (30; 130), via which drain the collecting gutter (21; 121; 221) communicates also with the vapor discharge channel (6) for draining condensate to the vapor discharge channel (6).

  • Patent number: 6089239
    Abstract: The invention relates to a hair dryer/styler having a diffuser with elongated fingers. In order to obtain a comfortable contact between the fingers and the scalp and a better individual adaptation of the fingers to the scalp during use of the hair dryer/styler, the fingers are arranged, individually or in a number of small groups, on resilient means. Preferably, each finger is arranged on one resilient arm.

  • Patent number: 6053181
    Abstract: An instrument for styling hair comprises a housing (9), a carrier (10, 11) which is movable supported by the carrier (10, 11), elongate hair guides (12, 13, 14) which project from the carrier (10, 11), a passage (15) for allowing hot air to pass through, and an air guide (17) which is controllable so as to direct the air stream in dependence upon forces exerted on the hair guides (12, 13, 14). The passage (15) and the carrier (10, 11) are adapted to influence the discharge direction in dependence upon the position of the carrier (10, 11) with respect to the housing (9). As the air guide (17) and the carrier (10, 11) are constructed in such a manner that the effective passage area of the passage (15) remains substantially constant when the discharge direction is changed, the air output and the temperature of the emerging air changes hardly when the discharge direction is changed. The hair-style is better under control and less combing and brushing is necessary.

  • Patent number: 5983517
    Abstract: The invention relates to a hair drying and styling appliance for drying hair by means of hot air. The appliance comprises a hair styling unit (8) which has a convex wall portion (9) formed with a multitude of air discharge openings (10) and the surface of the convex wall portion (9) has been provided with a velvet-like or short-tufted material (14). The styling unit further has a plurality of styling pins (12) are arranged along a peripheral part (11) of the convex wall portion (9). By brushing over the hair with the velvet-like or short-tufted material of the convex wall portion, the hair becomes is given a glossy appearance.

  • Patent number: 5894849
    Abstract: An instrument for styling hair comprises a movable carrier, elongate hair guides which project from the carrier, and a passage for allowing hot air to pass through. The passage and the carrier being adapted to influence the discharge direction in dependence upon the position of the carrier in such a manner that a pivotal movement in a first direction of the carrier with the hair guides which project therefrom results in a change of the discharge direction through the passage in a substantially opposite second direction. During use this prevents hairs just released by the hair guides passing through the hair from being muddled up again. The hair-style is better under control and less combing and brushing is necessary.
