Abstract: A washing appliance, particularly a laundry washer or a dishwasher, comprises a tank (2) for loading washing liquor and items to be washed and control means adapted to carry out a predetermined washing program. It further comprises an inclined drain surface (2a) for collecting a portion of the washing liquor and means (6, 8, 9, 10, 11, 12) for assessing properties of such liquid on the basis of the drainage behavior thereof.

Abstract: A washing machine comprises a tank for loading washing fluid and items to be washed and a control adapted to carry out a predetermined washing program. The washing machine comprises a first electrode electrically insulated from the washing fluid and a sensor connected to the first electrode for detecting a value of a sensor formed by the first electrode and by the washing fluid acting as a second electrode, the value being fed to the control in order to control and/or adjust the washing program.

Abstract: For an electric range featuring combined heating by microwave energy, and/or thermal energy a compact and space-saving construction impervious to microwave energy is provided by the thermal-energy source being arranged in a hood which is impervious to microwaves and which is formed at the top of the cooking space. A reflector associated with the thermal-energy source and situated in the transition area between the heating space and the cooking space is connected to a metal grid in an electrically conductive manner and is connected to but insulated from the housing.

Abstract: The air supply system for feeding air to a firebox within a building comprises a fresh air intake box (3) in the outside building wall (19) and, in the immediate vicinity of the firebox, a distributor box (7), connected with several pipes (5a, 5b, 5c, 5d). The fresh air intake box (3) has an extensible tube (25) for adaptation to varying wall thicknesses of the outside building wall (19). The prefabricated parts can be readily installed on the building site. By the use of several pipes (5a, 5b, 5c, 5d), the individual pipe cross section can be kept at a small value so that no static impairment of the building ceiling (11), wherein the pipes (5a, 5b, 5c, 5d) are extended, occurs. Advantageously, a fan can be installed in the extensible and readily removable tube (25) in order to increase the flow velocity of the fresh air; servicing of the fan is possible without any problems.

Abstract: A rapidly responding, electric thermometer for measuring surface temperatures is described which permits only a minimum heat transfer of temperature. The thermometer consists of a housing open at the bottom in which, ending with the lower edge of the housing, a temperature sensor is embedded by means of a poorly heat conducting material. The heat transfer between the lower part of the housing and the upper part of the housing is suppressed to a great extend with several radial slits in the housing which allow only two or more bridges to remain standing.

Abstract: There is described an electrical thermometer for measuring surface temperature consisting of a flat temperature probe having lead wires and a metal housing which only exhibits a very slight difference in temperature between the actual surface temperature and the measured value. The housing has a housing bottom, a recess or opening in the bottom, which is so dimensioned that the temperature probe and housing are not in contact. The temperature probe is positioned in this recess by means of a leaf spring secured to the housing.
