Title: Method of and device for separation of a suspension in water treatment
IPC: C02F1/52
Filed: 1964-10-02
Abstract: After coagulation, chemically-dosed water is passed through a sludge blanket zone where separation of suspension takes place, the water, depleted of suspension, flows from the sludge blanket zone to a clarified water zone where it is collected, and the water then passes to an expansion zone and thence to a granular filter bed in a filtration zone, the pressure required for flow of clarified water through the filter bed, being obtained by the head of water provided by the combined height of the sludge blanket zone, the clarified water zone and the expansion zone.  In an apparatus for performing the above method the zones above the granular filter bed are, in descending order: the clarified water zone, the sludge blanket zone and the expansion zone, with appropriate interconnecting piping or overflows.  A float at top water level regulates the final filtrate discharge valve.

Title: Apparatus for Ion Temperature Measurement
IPC: H05H1/00
Filed: 1966-09-12
Abstract: 1,157,147. Measuring ion temperature of plasma electrically. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. Sept.12, 1966 [Oct. 27, 1965], No.40605/66. Heading G1N. The ion temperature of a stream of plasma, e.g. in the ionosphere or interplanetary space, is calculated from a measurement of the ion density at two metal electrodes, e.g. of tungsten, placed in stream of plasma in a plane parallel to direction of flow of the stream. It is found that the ion density round the downstream electrode is less than that round the upstream electrode because the former electrode lies in the "shadow" of the latter electrode. This produces an asymmetrical currentvoltage characteristic for the electrodes from which the two saturation currents of the two electrodes can be determined and the ion temperature of the stream of plasma calculated. For measuring the ion temperature of a plasma stream from, e.g. a plasma gun, stationary electrodes are placed in the stream and are connected to a reversible D.C. or pulsed source. The voltage across the electrodes and current between the electrodes may be read off directly from a voltmeter and ammeter connected in the circuit, Fig. 1b, or may be fed to an oscilloscope, Fig. 1a (not shown), To measure the ion temperature of the ionosphere or interplanetary space, the two electrodes are mounted on the nose of a rocket or satellite, Fig. 4 (not shown), with their tips in a plane parallel to the direction of motion of the rocket or satellite.
