Title: Delignification bleaching of chemically produced cellulose pulp - involves activation with nitrogen peroxide and high temp. alkali treatment
Inventor: HANS
IPC: D21C9/10
Filed: 1981-12-16
Abstract: Cellulose pulp chemically produced from lignocellulosic materials is bleached by delignification by contacting the pulp, in an activation step in the presence of water, with a gaseous phase contg. NO2, oxygen gas being fed in such manner that the intermediate NO prod. is used to activate the pulp, the latter being then subjected to alkaline treatment. The activation step and the alkaline treatment are effected under severe conditions, i.e. at high temp. during activation, to obtain some degradation of the cellulose molecules and at 95-150, pref. 101-140, esp. 11-120 deg.C during alkaline treatment, the duration of treatment at the lowest temp. limit within these temp. ranges not exceeding 45,30 and 15 min respectively. The process does not involve use of chlorine and therefore does not produce toxic effluents. It is also more selective i.e. more lignin is eliminated while a high pulp viscosity is maintained Pulp yield and kappa index are also improved.

Inventor: THEVENON ALAIN
IPC: G01J3/04
Filed: 1982-01-05
Abstract: An optical device having a Paschen-Runge mounting arrangement, suitable for splitting up the polychromatic light emitted when the sample to be analyzed is being excited, comprising a frame (1) having the shape of a circle sector, an inlet slit (21) illuminated by polychromatic light, a concave diffraction grating (4) which diffracts the bundle of polychromatic light coming from the inlet slit, outlet slits (51) worked into a slit-carrier (5) and selecting the monochromatic bundles coming from the grating, and detectors for measuring the light fluxes of the monochromatic bundles. The slit-carrier (5) consists of a flexible continuous metal ribbon, and the cylindrical support bearings (122), which serve as supports for the slit-carrier, form part of the frame and are situated on either side of an aperture for the passage of monochromatic bundles, the ends of this ribbon being fixed to the frame (1). The device is intended to be mounted in a direct reading emission spectrometer.

Title: Flow energy conversion using water wheels and guide walls - uses guides to converge fluid flow and has hemi-cylindrical cut=outs in wall to shield returning side of wheel
IPC: F03B17/06
Filed: 1982-04-27
Abstract: The flow energy of rivers and streams is converted to rotational mechanical energy using a diverting wall built across part of the width of the stream, forcing the flow to converge into the water wheel enclosures which are hemi-cylindrical cut-outs in a wall, covering half the wheel from the flow but leaving the other half exposed to the flow. The water wheel has fixed radial arms carrying pivoted blades (8,9). The side of the wheel shielded by the hemi-cylindrical cut-out has the blades in the closed position perpendicular to the radial arm for minimum drag as they move through the water. A fixed gear segment is used to open the blades progressively out to the radial position when the blade is in the main flow, and to withdraw it again as the blade approaches the shielded region.

Application to the remote detection of toxic gases.
Patent FR-2527693-A1 (FR)
Inventor: SIMONDS EDWARD L
IPC: F02M9/08
Filed: 1982-05-25
Abstract: The invention relates to a fuel system for an internal combustion engine, with a housing which has a first chamber of cylindrical cross section in which an upper air inlet opening is located, which is opened to an air throttle, and a lower outlet opening, which is connected to the engine intake manifold, and in addition with a cylindrical coil which is pivotally mounted in the first chamber and has opposing openings, which are aligned with the said inlet and outlet openings as soon as the coil is located in its fully open position. In addition there is a second chamber in the housing, which is opened to the heat of the engine exhaust system and is separated from the first chamber by a partition wall and in which a fuel heating jacket is fixed, so that the heat of the exhaust system surrounds the heating jacket and thereby heats the internal chamber. A fuel nozzle extends in the fuel jacket through which fuel is fed to the jacket. In addition an air port is provided in the housing, through which port air from the outer chamber is directed into the inside of the fuel jacket. A fuel nozzle fixed in the wall opens at one end into the inside of the fuel heating jacket and at the other end into the inside of the coil, in order thereby to form a fuel outlet opening in the coil between the inlet and outlet openings. In addition there is a potentiometer for generating an analog voltage signal as a function of the position of the coil and a further potentiometer for generating an analog voltage signal as a function of the quantity of the air flow occurring through the housing. A sensor provided generates an analog signal as a function of the fuel temperature. A fuel injection valve is connected to the fuel supply and to the fuel inlet of the housing in series. Finally a circuit is provided for converting the coil position signal, the air flow signal and the temperature signal into an analog fuel demand signal and for converting this analog fuel demand signal into a pulsed direct current signal for controlling the fuel injection valve.

Title: Method and device for measuring the parameters used to guide a torpedo towards an elongated target
Inventor: GERARD VERNAY
IPC: G01S15/66
Filed: 1984-07-03
Abstract: Methods for guiding torpedoes towards their target. The sonar system of a torpedo comprises means for measuring deviations of phase (71) and amplitude (72) selected (70) according to distance. The echo returned by the target is analysed in detail in segments corresponding to the resolution in distance. The results of this analysis are subjected to statistical treatment in order to determine the target parameters more exactly. The invention enables the torpedo to be guided to the middle of the target and in a direction perpendicular to it.
