Abstract: The invention relates to a carrier material having an inorganic molecular structure and a surface coating produced by applying a substance and by heat treatment. The invention also relates to a method for the production and to the appropriate uses of said surface coating. Carrier materials made of glass, metal or ceramic should be provided with a surface coating with anti-sticking properties against water-based and/or oil-based organic materials or water-oil emulsions while exhibiting at the same time essentially better temperature-resistant and anti-scratch characteristics than conventional PTFE or silicon coatings. The requirements are met by an inventive surface coating consisting of a combination of inorganic molecules of the carrier material and organic molecules of an applied substance on the uppermost molecular layer of said coating. In order to produce such a surface, an inorganic substance with silicone-like networks is initially applied.

Abstract: The invention relates to a laundry treatment apparatus like washing machines, laundry dryers or a washer-dryers with a rotatably mounted drum (6) with an at least approximately horizontal axle and with a drive motor (10) structured as a synchronous motor (10) energized by permanent magnets arranged on the drum (6) shaft, the stator (16) of the motor (10) being provided with a winding (18) which is energized by a converter. In order to optimize the motor in such machines in respect of energy consumption, noise development and costs it is proposed to design the winding (18) as a single pole winding, whereby the number of stator poles (27) and of the magnet poles (23) is different, and to utilize a frequency converter (104) as the converter the output voltage of which being set such the continuous currents are generated in all winding strands.

Abstract: The invention relates to a washing machine or a washer-dryer with a drum (3) mounted in a suds basin (2) for horizontal or inclined rotation and having a cylindrical wall (3.1) and to cover plates (3.2; 3.3), the cylindrical wall (3.1) or one of the cover plates (3.2; 3.3) being provided with a removal opening and the cylindrical wall (3.1) being made in part or completely from sheet metal provided with a texturized bulges facing the interior of the drum. In order to provide for an optimally gentle laundry treatment at the same time as good visual appearance and complete exhaustion of residual water the holes (16) in the cylindrical wall (3.1) are disposed on the outwardly facing marginal contours (17.1) of the bulges>alternatively, the holes (16) may be disposed in sections (3.5, 3.6) of the cylindrical wall (3.1) formed without bulge texturization.

Abstract: A method and apparatus for two-coat one-fire electrophoretic enameling of a work piece made of metal, wherein a first undercoat enamel slip deposit bath is followed by at least one excess slip removing bath before the undercoated work piece is submerged in a process bath including an additive for reducing the electrical resistance of the enamel biscuit followed sequentially by another rinsing bath, a finish enamel coating bath and not less than one final rinsing bath before the coated work piece is subjected to an enamel firing step.

Abstract: A program controlled dishwasher in which magnetic sensors provided adjacent to the dishwasher door respond to magnetic fields of predetermined polarization provided by permanent magnets in a catenulate magnetic key mounted on a dishwasher caddy in a position adjacent the magnetic sensors when the caddy is in the tub of the dishwasher, for generating a verifiable code pattern readable against dishwasher stored programs for the selection and actuation of a program specific to the articles which are stored in the caddy for washing. The polarization patterns on the caddies are specific to the kind of articles stored therein and may be readily altered to accommodate different articles.

Abstract: The warehouse has a high storage density and is suitable for the storage of bulk goods. The warehouse has at least three superimposed storage areas. A storage area is laid out as the operational level for the storage and withdrawal of the goods. A further storage area consists of a storage level with one or more superimposed storage levels for storing and consigning goods. A further storage area is used as an auxiliary operational level for preparing roller pallets and taking them to the operational level.

Abstract: In a cutlery-holding basket (5) for a dish-washing machine (1), in which the items of cutlery (6) which are to be washed and dried can be individually laid down lengthwise alongside one another in separate cutlery holders (9a) and cutlery supports (9b), the cutlery supports (9b) are constructed with differently profiled support surfaces (11) and/or different support heights. Because of this measure, it is equally possible for any arbitrary collection of items of cutlery (6) from various different sets of cutlery to be cleaned and dried in an optimal fashion.

Abstract: In electrophoretic immersion enameling, about one-third of the enamel slimes charged is admitted into the rinsing basin, with this basin being located downstream of the immersion enameling basin. The process and the device for carrying out the process of the invention effect an efficient recovery of the enamel slimes. In the process, the electro-immersion enameled parts are wholly or partly sprayed off above the immersion enameling basin and/or an after-connected additional basin. The overall water system is kept constant by draining cells arranged and integrated into the immersion enameling basin or in the additional basin.

Abstract: A preferred drum-type washing machine includes a housing having an interior and a housing lid which is placed in an open position for access to the interior. A detergent container is disposed within the interior of the housing and includes a detergent container lid which is aligned with the housing lid. The detergent container lid is for access to an interior of the detergent container when in an open position when the housing lid is in the open position. A wash drum is mounted for rotation about a horizontal axis within the interior of the detergent container. The wash drum includes a drum lid which is for alignment with the detergent container lid and, when in the open position, allows access to the interior of the drum. The drum lid is in a closed position for rotation of the wash drum. There is included a positioning device for positioning the drum in a loading position at which the drum lid is aligned with the detergent container lid.

Abstract: A washing machine which includes a wash tub for receiving water and articles to be washed, a drain connected to the wash tub, a float disposed within the drain, a drain water reservoir for receiving and storing water removed from the wash tub through the drain and for providing back pressure on the float, and a pump for pumping water from the wash tub, through the drain, and into the drain water reservoir.

Abstract: On a rotary switch apparatus for the cycle selection on a washing machine, the cycle data are arranged in a circular fashion around the rotary switch. Variable adjustable temperature ranges are assigned to each wash cycle, so that appropriate temperature values can be individually set and selected for various types of fabrics.

Abstract: The invention concerns a method for firing enamel on steel parts, especially on steel sheet of aluminum stabilized continuous cast steel material, as well as an enameling oven with a firing zone and an entry zone serving as a prewarming zone for the carrying out of this process. The invention is characterized in that the heating of the steel part or steel sheet to the firing temperature is interrupted before reaching the firing temperature, in that hydrogen dissolved in the steel is released during the interruption time, that the steel part subsequently is heated further to the firing temperature, is held at this temperature and is then cooled in a known way. The enameling oven for carrying out the method consists according to the invention of a degasing zone inserted between the firing zone and the prewarming zone, in which degasing zone the workpiece coated with enamel is held for a given minimum time at a definite temperature.

Abstract: There is provided a vacuum cleaner, particularly a floor vacuum cleaner with a rack or holder for the vacuum hose pipe, the rack is a two-part unit consisting of a separate pipe holder which can be slid onto the pipe extension of a vacuum hose and a mount for the pipe holder assembled on the vacuum cleaner housing. The arrangement and the configuration of the vacuum hose rack are such that the vacuum hose pipe can be secured onto the side of the vacuum cleaner housing.
