  • Patent number: 4918294
    Abstract: The invention is directred to an electric heating in a bread toaster, comprising an insulating body (11) and heat conductor portions (14, 14') which may be arranged on both the front part and the back of the insulating body (11) and are pressed thereagainst by mounting strips (21). To compensate for uneven browning of the article to be toasted--which is caused by the bread toaster being cooled by an air current entering at its bottom and subsequently flowing mainly in the area of the center axis (X) of the insulating body (11)--, it is suggested to provide the mounting strips (21) on the insulating body (11) spaced from one center aixs (X) and thus substantially outside the range of action of the air current.

  • Patent number: 4911067
    Abstract: The infusion beverage maker (1) is composed of a tank (3) supplying water which connects via a water pipe (4) to a continuous flow heater (5). A hot water line (10) emanating from the continuous flow heater (5) terminates into a supply port (11) arranged above the filter unit (12), the said filter unit (12) being detachably mounted on the housing (2) of the infusion beverage maker (1). Fixed to the bottom side (41) of the filter unit (12) is a valve assembly (43) forming a valve (18) and controlling the discharge of the infusion beverage into a storing receptacle (27). For every type of infusion beverage to be prepared, there is provision of one separate filter unit (36) each which, in case of need, can be substituted for the previously used filter unit (12).

  • Patent number: 4904845
    Abstract: An electrical continuous flow water heater for an infusion beverage making appliance includes a hot plate serving to keep hot a beverage receptacle and which is located above and in heat exchange relationship with a heater element and water supply pipe disposed in a horse-shoe configuration. The temperature controller for controlling the temperature of the hot plate is mounted on one of a plurality of ribs provided on a support device thermally coupled to at least one of the supply pipe and heater element. Each rib is so sized and shaped and so located relative to the supply pipe and/or heater element to deliver solely through the rib a different amount of heat to a temperature controller mounted thereon. The temperature sensed by the controller is determined by the particularly rib on which the controller is mounted, thus permitting one type of continuous flow heater to keep hot flasks of different fill capacities place on the hot plate.

  • Patent number: 4894813
    Abstract: The invention is directed to an alarm shut-off device for an alarm clock or timer permitting a signal delivered by the clock to be interupted or to be cancelled in that the user of the clock approaches the clock or merely moves a part of his body, for example, his hand, towards the clock. Preferably, the clock is equipped with a transmitter 2, 2' emitting infrared radiation or ultrasonic waves and a corresponding receiver 3, 3' which detects the infrared radiation or the ultasonic waves reflected by the moved body part 1. A signal shaping network 4, 5 and 6 determines the variation of the intensity with time, which variation is compared in a threshold switching stage 7 with a predeterminable value which, when exceeded, causes the alarm signal A to be shut off.

  • Patent number: 4893552
    Abstract: A beverage making machine includes a housing with structure defining a storing receptacle receiving region and support structure above the storing receptacle receiving region, and filter case structure for releasable engagement with that support structure. The filter case structure has an outlet in which an anti-drip valve is disposed. A valve operating mechanism includes biasing means for biasing the valve to its closed position, and one piece lever structure is connected between the biasing means and the valve for moving the valve to its open position. The one piece lever structure is deflectable about a first axis of rotation by a stop on the housing as the filter case structure is inserted into the beverage making machine without opening said anti-drip valve, and, insertion of the storing receptacle beneath said filter case structure moves the lever about a second axis of rotation to open the anti-drip valve.

  • Patent number: 4890395
    Abstract: The invention is directed to a hair dryer in which the heating device, the switch, the igniting mechanism and the gas tank are provided by a conventional gas-operated pocket lighter (17) preferably equipped with a battery ignition or piezoquartz ignition or, in an alternative embodiment, by a disposable lighter using flint ignition (40). It is also within the scope of the invention to use an exchangeable gas tank, with the igniting device being fixedly arranged in the hair dryer housing. The ignition process is started as the lighter (17 or 40) is inserted into the recess (21 or 21a) of the hair dryer housing, with the blower (2) being started briefly before by contact of the laminae (18 or 18a). The blower current is supplied by either disposable batteries or rechargeable accumulators. The hair dryer of the invention is turned off simply by easing the thumb pressure, which ensures at the same time that the appliance does not continue running accidentally when put away.
