Patent EP-0018120-A1 (EP)
Inventor: WONG WILSON TIN-CHE
IPC: G06F7/52
Filed: 1980-03-31
Abstract: The invention provides a fast multiplier circuit in which the multiplying operation is arranged to skip the teps of multiplying by sections of the multiplier which consist only of trailing zeros. …<??>The multiplier sections are applied to a non-zero detector (12) which produces an output whenever there is a non-zero bit in the word section. This output is applied to control register (13) which in turn supplies a signal to the shift counter (14) controlling the multiplication operation, thereby causing multiplier sections containing only trailing zeros to be skipped. …<??>The multiplier register (10) may comprise separate register portions (MQ-A, MQ-B, MQ-C, MQ-D) each of which stores a separate word section and may be on a separate micro-ship, and a multiplexer (11) responsive to a word-number supplied by the control register (13) is arranged to supply sequentially the digits of the non-zero sections of the multiplier from the appropriate multiplier register portion to a multiplier decode circuit (93) for carrying out the multiplication steps. …<??>Each of the multiplier register portions (MQ-A, MQ-B, MQ-C, MQ-D) may be in two parts arranged in parallel, one of them holding the odd bits and the other the even bits, and the multiplexer (11) may accept the digits in pairs in parallel from the two register parts.

Abstract: In a process for the treatment of in particular water-containing nitrate, such as, for example, ground water, brackish water or the like, the water is separated into a low-nitrate permeate and a high-nitrate concentrate by means of reverse osmosis and the latter is evaporated until precipitation of the solid. In order to be able to operate such a process more cost-efficiently, the concentrate is freed from hardness formers, concentrated by means of a membrane separation process to give a salt solution, which is then evaporated.

Abstract: A process for producing a low-fat oil-in-water-in-oil emulsion, particularly a low-fat spread, comprising (a) feeding the fatty phase which constitutes the continuous phase of the final emulsion into a system comprising an emulsification unit and units where cooling and working are carried out for a period of time long enough to at least achieve coating of the inner surface of said emulsification unit with said fatty phase and preferably for a period of time long enough to remove substantially all the air present in the emulsification unit, and (b) introducing in the system increasing amounts of a proteinaceous oil-in-water emulsion which is preferably substantially free of gas dissolved therein, until the desired concentration of fat in the end product is obtained. The fatty phase and the proteinaceous emulsion are preferably fed into the emulsification unit as concentric streams whereby the fatty phase constitutes the outer stream and the proteinaceous emulsion constitutes the inner stream.

IPC: G01N27/419

Abstract: This specification discloses a device to determine the percentage of oxygen in an ambient atmosphere. The device, which is immersed in the atmosphere, is constructed to define an enclosed volume in which the atmosphere can be established by means of a small leak. The enclosing structure contains two partitions which can conduct oxygen ions and act as electrochemical cells. One partition is called the pump cell while the other is called the sensor cell. When attached to an external power supply, the current (Ip) drawn through the pump cell either adds or removes (from or to the ambient) gaseous oxygen from the volume. As a result of the pumping action, an EMF (V s ) develops across the sensor cell which can be used to measure the change in oxygen partial pressure in the volume relative to the ambient. If an external circuit causes adequate current to flow in the pump cell to keep the sensor EMF at a constant value, then the magnitude of the current is linearly proportional to the percentage of oxygen in the atmosphere.

Abstract: A stress compensated thickness-shear resonator is of an orientation (yxwl) φ/θ selected from loci of stress compensated orientations provided for both the fast and slow thickness-shear modes of vibration. A stress compensated orientation is used in an oscillator for stable frequency-stress behavior. A stress compensated orientation having large-valued temperature coefficients of frequency is used in a temperature sensor for precision measurements. A stress and temperature compensated orientation is used in a pressure sensor such that the temperature compensated thickness-shear mode is used for pressure measurement while the stress compensated thickness-shear mode is used to compensate for effects of temperature.

Abstract: Procede de repartition de l'usure due a des vehicules circulant sur la surface d'une route, selon lequel des marques individuelles (3, 3', 4, 4', 5, 5') sont appliquees sur la surface de la route de chaque voie (1, 1') espacees les unes des autres et s'etendant dans le sens de la route. Ces marques sont appliquees cote a cote sur une distance qui correspond essentiellement a la largeur de chaque voie (1, 1'), et elles sont situees dans les voies (1, 1') de telle maniere que des vehicules circulant dans les voies (1, 1') et passant sur les marques (3, 3', 4, 4', 5, 5') avec les roues adjacentes aux marques (3, 3', 4, 4', 5, 5') maintiennent la distance normale entre eux, ce qui correspond a des vehicules circulant au centre des voies (1, 1'). Lorsque les marques (3, 3', 4, 4', 5, 5') sont effacees, a cause de l'usure due aux vehicules passant sur les marques (3, 3', 4, 4', 5, 5'), un nouvel ensemble de marques (3, 3', 4, 4', 5, 5') est applique, deplace legerement de cote par rapport aux marques appliquees precedemment (3, 3', 4, 4', 5, 5'). Ces marques (3, 3', 4, 4', 5, 5') sont de preference peintes sur la surface de la route en couleurs differentes aux lignes de marquage des routes, et comprennent egalement un symbole. En repetant l'operation decrite ci-dessus, les vehicules sont deplaces successivement d'un cote de la route vers l'autre, distribuant ainsi l'usure sensiblement sur toute la surface de la route. Chaque voie (1, 1') peut aussi recevoir deux lignes de marques espacees (3, 3', 4, 4', 5, 5') a une distance interieure correspondant essentiellement a l'empattement des types de vehicules conventionnels, de maniere telle que les conducteurs essaient de placer les vehicules par rapport aux marques (3, 3', 4, 4', 5, 5') pour que toutes les roues passent sur les marques appliquees (3, 3', 4, 4', 5, 5').

Abstract: The invention concerns a method and apparatus for dispensing of oxygen and liquids in biological systems, wherein the dispensing is powered by a drive gas formed by the continuous catalytic decomposition of hydrogen peroxide to form water and oxygen. The decomposition of hydrogen peroxide takes place in stages, wherein in a first step only a first amount of gas is liberated in a first container and a further decomposition of hydrogen peroxide takes place in one or more further containers. This method and apparatus are particularly suitable for the continuous production of oxygen, decontamination and disinfection in aquaria and free standing water as well as for the watering of plants and the supply of drinks for animals, where suitable active ingredients can be added to the water.
