Abstract: A valve (9) for integrating into a sanitary appliance e.g. a urinal (1), including two lug-type elements (21) that are arranged parallel to each other on the lower end of a funnel-shaped inflow section (17). The elements (21) are interconnected on the ends of the lower edge (23). Slits (33) can also be made in the elements (21), enabling the escape of liquid when there is a large amount of throughflow.

Abstract: A method for determining the point in time for the replacement of one or more of wearing parts, blocking fluids and fragrance and cleaning substances, dependent on the use of a sanitary apparatus, includes the step of placing an indicator element in the run-out region of the sanitary apparatus, which indicator element has an optically recognizable chemical or physical conversion indicator that provides an observable conversion after a predetermined, or pre-set, number of uses, or wettings, of the sanitary apparatus for altering maintenance personnel that maintenance of the sanitary apparatus is required. An apparatus for performing the method is also provided.

Abstract: Disclosed is a process for the reprocessing or production of a sputter target or an X-ray anode wherein a gas flow forms a gas/powder mixture with a powder of a material chosen from the group consisting of niobium, tantalum, tungsten, molybdenum, titanium, zirconium, mixtures of two or more thereof and alloys thereof with at least two thereof or with other metals, the powder has a particle size of 0.5 to 150 ?m, wherein a supersonic speed is imparted to the gas flow and the jet of supersonic speed is directed on to the surface of the object to be reprocessed or produced.

Abstract: A waterless urinal (1) is provided with a pot (17) in which urine (35) accumulates. A float (33) floats on the urine (35) and is pressed upwardly by the buoyancy thereof against an opening (31) in the cover (29) of the pot (17). As soon as a pre-determinable column of urine rises above the float (33), the float (33) is pressed downwardly, and the urine (35) can flow out. In a preferred embodiment, the float (33) can be pulled downwardly by an electromagnet, in order to sporadically empty the urine (35), which has accumulated above the float (33) and the cover (29).

Abstract: A device for introducing an endoscope or a surgical tool into body cavities with a feed for a flushing medium and an extractor for said flushing medium, which permits as versatile as possible an application of the endoscope or tool and maintains a higher pressure in the interior of the body as compared with the environment. The device includes a sluice, insertable into the body cavity from outside. The sluice has a cylindrical stem along whose inner wall extend two separate longitudinal grooves which have openings at their ends which pass through the wall of the stem. The openings outside the body are connected to the feed and the extractor for the flushing medium. A cylindrical endoscope or tool is inserted into the device with its outer wall tightly contacting the inner wall of the stem. The outer wall of the endoscope or tool, together with the longitudinal grooves of the stem, form sealed channels for the flushing medium.

Abstract: A method and circuit arrangement for selective correction of hues and colors in the production of color separations for polychromatic mixed printing. A hue signal identifying the hues of the scanned colors as well as a color saturation signal and a luminance signal are derived from the measured color value signals acquired when scanning the original. Hue signals, color saturation signals and luminance signals are limited such that they are respectively not equal to zero only for selectable regions. The region of the hue signal defines a hue to be selectively corrected, and all three regions of the signals define a color to be selectively corrected. At least one of the limited signals is combined with at least one of the unlimited signals to form the selective correction signals which are superimposed on the color signals to be corrected.

Abstract: A welding sleeve for connecting pipes formed of thermoplastic material includes an electrical conductor in the form of an electrical resistance wire. The resistance wire extends around the sleeve and has a pair of opposite ends for conveying current through the wire. The opposite ends of the wires can be connected directly to a source of electrical current, for instance a 220.degree. V.about.line. It is not necessary to provide transformers or timing relays. A melting material is incorporated into the conductor between its ends and it melts through when the energy necessary for welding the sleeve has been developed. After the current is supplied through the resistance wire, the welding process is completed when the predetermined melting material melts through. Such sleeves can be manufactured in a mass production operation, and the sleeves are much safer than the conventional devices used to-date.

Abstract: A combination lock having a lock housing with a spring bolt. A manually operable combination dial is provided outside the housing to operate a standard combination mechanism and a bolt retracting cam. A bolt retracting element is secured to the bolt and engageable by the bolt retracting cam when the combination mechanism is operated to a predetermined condition. By turning the dial the retracting cam is operated and the bolt is retracted. A disengagement mechanism disengages the bolt retracting element from the retracting cam, after the dial is released and the bolt is then displaced to its locked position.

Abstract: This invention relates to the production of a printing block or form of the kind in which at least one original is scanned optoelectronically to obtain image signals being mixed to generate a composite signal and is recorded as the printing block or form, one of the image signal which is to be mixed being modulated by a control signal and the other image signal being modulated by the amplitude-inverted control signal and the modulated image signals being summated to obtain said desired composite signal, said control signal determining a mixing range and the mixing characteristic within said mixing range.According to the invention, the said control signal is derived from the color information of a colored control mask by scanning said mask or from the image content of the original.

Abstract: A process for the identification of a predetermined plurality of colors on the surface of an object which is scanned by electrical-optical means to produce measured signals substantially representing the colors red, green, and blue coordinates, the plurality of colors defining color-regions, and defining color-identification-regions, wherein the boundaries of the identification-regions are simulated electronically through threshold-value circuits for each of the coordinates, the output signals of which are transferred to coincidence circuits, which indicate the presence of one of the plurality of colors when the coordinates of the color signals lie within the color-identification-region.

Abstract: A method for the electro-optical reproduction of half-tone pictures in which the picture is subdivided into surface elements having covering spots therein corresponding to a tone value scale, wherein electronic recording data is produced from the surface elements and is stored, wherein by means of electrooptical scanning of a picture signals are obtained and are used to call up the recording data for the reproduction of the picture, the improvement resides in that several raster screens on the picture are formed and the meshes and the angle of rotation of such raster screens are selected in such a manner that an orthogonally oriented parcel screen having a congruent screen structure is obtained, and subdividing the parcels into smaller orthogonally oriented surface elements and obtaining recording data from such surface elements.
