Abstract: The invention relates to a primary switching power supply having an auxiliary voltage supply (2) on the primary side for a control unit (4) of a primary power switch (20) connected downstream of the primary winding (22) and having a run-up branch (16) containing run-up resistor (34), the auxiliary voltage supply (2) containing a winding (6) which runs with the latter and electrically parallel to which a series circuit consisting of a diode (8) and a capacitor (10) is connected, and the run-up resistor (34) connecting an auxiliary voltage input (14) of the control unit (4) to a positive, primary input terminal (18). According to the invention, a switch (38) which can be driven by means of a two-level controller (24) is connected between the run-up resistor (34) and the auxiliary voltage input (14) of the control unit (4). Thus, a primary switching power supply having a primary auxiliary voltage supply (2) and a particularly low-loss run-up branch (16) is obtained, by means of which the degree of efficiency of the switching power supply is not worsened and an immediate switching on is possible. <IMAGE>

Abstract: A memory is described which incorporates redundancy in the form of one or more redundant columns. An applied binary address is first distributed between predecoders which form a 1-out-of-2 n  code from n bits received. For each non-redundant column there is available a part of a main decoder, each part receiving a different combination of the bits supplied by the predecoders, thus selecting the column. For each redundant column there is provided a redundancy decoder. The latter decoder receives all bits supplied by the predecoders, each time via a series connection of a activatable gating element and a fuse element. Per predecoder the outputs of the series connections are combined in a wired logic function. Each wired logic function forms an input signal of the actual redundancy decoder. When a redundant column is to be addressed, all fuse elements but one of a group are opened and the gating elements are activated. A memory column to be replaced is then uncoupled by way of another fuse element.

Abstract: An overhead transparency system which enhances the density of images printed on film by ink-jet techniques is provided. The film is coated with a layer of a transpar­ent, hydrophilic material to a thickness which promotes controlled lateral diffusion of the printed ink. 
     The lateral diffusion is microscopically observed to begin within 1 minute after printing, eventually ceasing as the vehicle of the ink is sufficiently spread and eva­porated by the lateral spreading. The optical density of the image increases as the ink diffuses, reaching a maxi­mum density that is considerably greater than otherwise possible without an ink-coating system. 
     Sheets of such printed transparencies are protected by insertion between sheets of a vapor permeable, water absorbent material such as cellolose acetate.

Abstract: An optical filter comprises a volume diffraction grating (1) provided within a waveguide. The grating (1) has a thickness T sufficient such that when an optical beam R is incident on the grating from outside the waveguide, wavelengths at or near the Bragg wavelength for the grating are diffracted and coupled into the waveguide, all but the first order interferences being substantially eliminated, whilst wavelengths away from the Bragg wavelength pass through the waveguide substantially undiffracted. The grating pitch L may be varied to permit tuning of the filter response.

Abstract: In a process for producing an ether, at least one light olefin is contacted with water and an alcohol recovered from a downstream distillation operation in an olefin conversion unit in the presence of an acidic zeolite catalyst to provide an aqueous mixture of the alcohol and an ether, the olefin conversion unit being operated under conditions effective to provide the alcohol by the reaction of olefin and water and the ether by the dehydration of the alcohol and/or by the reaction of the olefin and the alcohol. The aqueous mixture of the alcohol and the ether is then introduced into a distillation unit which is operated under conditions effective to provide an azeotropic overheads fraction comprising the ether and minor amounts of the alcohol and water, and a bottoms fraction comprising aqueous alcohol. At least a portion of the bottoms fraction is recycled into the olefin conversion unit and, the azeotropic overheads fraction is introduced into an alcohol separation unit which is operated under conditions effective to provide an ether product containing at most negligible amounts of alcohol and water and an aqueous alcohol product.

Abstract: The process involves illuminating the component (12) to be measured with a focused laser beam, which is then reflected from the surface of the component. The reflected ray is detected by an array of diodes (27). A computer (35) records the successive indices idmj of the diode Dj in the array, which has detected successive peaks in amplitude for a set of steps in the discontinuous movement of the component in the X direction. The geometrical outline of the component is reconstructed by rotating it in front of the incident beam.

Le filet à mailles peut être formé de mailles en fils métalliques résistants, pour assurer une protection contre le risque de chute d'objets sur la structure. Une toile tout temps (de protection contre la pluie essentiellement) peut être placée dans les régions indiquées en B. Cette toile peut également former une couverture en matériau flexible pouvant être ouverte ou fermée, selon les conditions climatiques du moment. Cette toile peut également contenir un matériau ignifuge. Une autre toile tout temps ou un matériau de protection contre le soleil peuvent également être prévus au régions C et D et les câbles en D peuvent également porter un système d'arrosage aérien, pouvant par exemple être utilisés dans des serres. Les câbles de support principaux (2, 3 et 4) en B et C peuvent être en forme de tubes pour des petites structures, mais pour de très grandes structures, des câbles métalliques sont généralement nécessaires.

Abstract: For controlling polyphase machines (15) in electrical drive systems and in the electricity supply industry, electrical measurement quantities for the reactive current, active current, the reactive power, active power and the power factor are required. In the case of remote transmissions and in relatively large systems, digital quantities are preferably used. To reduce the complexity in the conversion of analog electrical measurement quantities into digital quantities, the voltage zero transitions of the phase-to-phase and open alternating voltages are detected (7) and at the time of the voltage zero transition (So), the corresponding actual phase current values are detected and stored in a sample and hold element (6). The zero transition of a phase voltage produces a corresponding reactive current value. The zero transition of a phase-to-phase alternating voltage produces an active current value and an amplitude value of a phase voltage, which is stored in a sample and hold element (6'). These stored current and voltage values are successively supplied via a channel selection device (8) to an analog/digital converter (9) and temporarily stored in a shift register (10) over 60 DEG  electrical. The digitised measurement quantities are subsequently evaluated by means of a microcomputer (11), which, among other things, controls the polyphase machine (15) via a digital/analog converter (12), an ignition signal generator (13) and a control converter (14). <IMAGE>

Abstract: A process for preparing decorative granules which can be used, for example, in the design of the surfaces of structured wallpapers is described. For preparing the granules, a pasty mass (8) is transferred, for example by means of a screen-printing cylinder (2), in discrete quantities or surface areas (26) to a carrier surface (10) which can be the surface of a rotating cylinder (4) or of a revolving belt. The cylinder (4) or belt is associated with at least one heating device (18) for solidifying the mass. After passing through a cooling unit (20), the finished granules (28) are lifted off the carrier surface (10) by means of a scraper (22). An additional printing mechanism can also be inserted, by means of which the surface of the particles is provided with a decorative imprint. Particles of defined size and shape and defined size distribution can be prepared by the process described. Depending on the starting mass and the treatment, the particles can have different properties, for example they can have been foamed by means of a blowing agent. <IMAGE>
