Abstract: In an apparatus which supplies characters or symbols and which is intended for service in different countries, some characters or symbols must have different forms for different countries or groups of countries. In the case of read-out apparatus which reproduces in dots, such as matrix printers or displays, the character forms are usually stored in a read-only store, a given address being assigned to each character. In order to achieve simple addressing in the case of a character which has different forms in different countries, not the character form is stored in the corresponding storage location, but rather one or more addresses which indicate in which location in the character store the relevant, country-dependent character form is present. To this end, each storage location comprises an additional storage (bit) position which indicates whether or not address information is concerned and which is read and interrogated first. Depending on the contents of this storage position, either the remainder of the store is then read and transferred to the read-out or an address in the address control system is read and transferred; after that the special character form stored at this further address location is read.

Abstract: A complementary integrated circuit in MOS technology contains at least one P-channel FET (18) with insulated gate (24) and one N-channel FET (16) with insulated gate (26). A closed geometry results in fast transistors with a high packing density. Drain zones (38 and 42) are surrounded by frame-like gate structures (24 and 26) which, in turn, are surrounded by source zones (40 and 44). To insulate the transistors, a layer (22), which is also closed in the manner of a frame, of conductive material is provided which acts as insulating gate. This also results in space-saving isolation of the transistors. In production, a self-aligning gate technique is used, the layer (22) being produced at the same time as the gates (24, 26). A single mask setting can be used for making a plurality of diffusions. <IMAGE>

Abstract: A phase modulation modem providing switch selectable speeds on voice-band channels utilizes four phase, modified eight phase, and optimized eight phase, two amplitude modulation techniques. A binary equalizer automatically corrects for envelope delay and amplitude distortion of the carrier signal caused by the voice-band channel. Each symbol time, the X-axis error and Y-axis error for the received symbol is determined by comparing the received X and Y components with stored ideal X and Y components for that symbol. These error X and error Y values are used to modify primary and secondary equalization constants. The equalization constants, thus modified during this symbol time, are used on the next received symbol to correct for the phase and amplitude distortion measured during past symbol times. This sequence is repeated for each symbol time. Preselected equalization constants are utilized on the first symbol received. To equalize the line very rapidly at start-up, a phase training signal is sent prior to data transmission. After this "course" adjustment the equalizer operates on the received data symbols to very accurately correct the phase and amplitude distortions of the received symbols. A symbol quality signal is conveniently generated as a result of the equalizer operation.

Abstract: An automated analysis process and apparatus for analyzing the amount of dispersed water-immiscible solid organic substances in sewage water whereby a precise sample of sewage is taken from a sewage source, admixed with various reagent solutions, including a K2Cr2O7-solution under heat-time conditions so that a reaction occurs between the sewage and the reagent and all of the organic substance in the sample are oxidized while simultaneously at least some Cr+6-ions are reduced to Cr+3-ions. During this oxidation-reduction reaction and at a location remote therefrom, a precise amount of Fe+2-ions is generated within an aqueous acidic Fe+3-ion containing solution via a coulometric reduction process. Thereafter, the reacted sewage-reagent solution is admixed and reacted with the so-generated Fe+2, Fe+3-ion containing solution so that any residual Cr+6-ions in the sewage-reagent solution are reduced to Cr+3-ions and at least some Fe+2-ions remain. By biamperometrically titrating the resultant Fe+2-ion containing solution with a standardized Cr+6- ion containing solution, the precise amount of Fe+2-ions within the titrated solution is determined and this provides an indirect indication of the amount of organic substances within the sewage sample. Pneumatic, hydraulic and electrical circuits actuate the various steps and are themselves actuated and controlled by a master control means, such as preprogrammed computer means, which also computationally integrates data from the overall process and automatically determines the amount of organic substances in the samples under analysis.

Abstract: Apparatus for converting ocean surface wave energy into useful rotational kinetic energy. A refractive horn and ramp provides reflectionless impedance transformation of ocean surface wave energy at the input to the system. Wave energy, in the form of breakers, which are massive pulses of essentially pure kinetic energy, from the output of the horn/ramp are then smoothed and transformed directly to mechanical rotation. Smoothing is accomplished by the inertial properties of a "liquid flywheel". The rotational kinetic energy may be extracted by means of a turbine to provide useful work. Discharged water is returned to the ambient ocean through a low terminal velocity diffuser. The entire structure may be located offshore and the discharged fluids may be used for auxiliary purposes.

Abstract: A printing device adapted to print a bar code on a moving information carrier, preferably in the form of a label for marking an article or packaged goods, said bar code consisting of a plurality of parallel bar imprints of different widths separated by spacings lying therebetween. The invention is characterized in that there is provided one single printing member for all of the bar imprints of the bar code, the imprint width of said printing member being not greater than the smallest width of any bar imprint appearing in said bar code, and said printing member being operatively connected to an actuating unit coupled to a programmable control unit, which is adapted to generate control signals at small enough time intervals to form bar imprints of larger width by juxtaposing of bar imprints of the width of said printing member without intervening spacings. The use of only one single printing member not only results in a considerable structural simplification, but also permits the printing device to be universally employed for any existing and future bar codes, the narrowest bar imprints of which correspond to the imprint width of the printing member. The narrow printing member produces a sharply defined and accurately readable imprint also for bars of larger width.

Filed: 1982-04-21
Abstract: The radiation distributor is for a fibre-optic measurement unit where the sensor works in accordance with the principle of excitation light wavelength shift to one of luminescence. Excitation and luminescence from the sensor are transmitted on the same light conductive fibre (2). The excitation light is converted by an optic unit to a parallel radiation bunch (3) which is reflected towards a component (4) with wavelength-dependent reflection, and which is connected into the sensor fibre (2). Luminescent light coming from the sensor fibre (2) is likewise converted to a parallel radiation bunch using an optic component. This radiation bunch passes onto the same optic component (3) with wavelength-dependent reflection, from which it is connected to at least one detector (7). The optic component with wavelength-dependent reflection can be an interference filter, a grid, or a prism provided with a reflector. (Provisional Basic advised week 83/49).
