Abstract: 1345095 Measuring particle mass and conceritration COMMISSARIAT A L'ENERGIE ATOMIQUE 4 Oct 1972 [18 Oct 1971] 45807/72 Heading G4H [Also in Division G1] The mass and concentration of particles carried by a fluid 60 (Fig. 2a) is determined by a flow-meter 68, measuring the rate of flow of the fluid, and a piezoelectric transducer 62 bombarded by the particles to produce output pulses whose amplitudes represent the mass of the particles and whose frequency is also determined. In one embodiment (Fig. 4), the transducer 62 has a measuring piezoelectric element 32 and a compensating piezoelectric element 34 rigidly attached to opposite faces of a metal cylindrical block 40, the outer face of element 32 being at an oblique angle to the direction of flow to prevent particles from impinging twice on the element. The piezoelectric elements are electrically connected in opposition to cancel the effects of common vibrations, and embedded in insulating material 54 which also damps out spurious pressure waves. In an alternative arrangement the transducer 62 is moved at a known constant rate in the fluid. The prior art is stated to include an arrangement of two piezoelectric elements 2, 4 (Fig. 1) determining the frequencies of oscillators 6, 8, wherein element 2 is coated with adhesive to trap impinging particles so that its resonant frequency is reduced by an amount measured in a mixer 10 also fed with the reference frequency of oscillator 8.

Abstract: 1309195 Welding by pressure; making tubes ALUMINUM CO OF AMERICA 1 Oct 1971 [2 Oct 1970] 45821/71 Headings B3A and B3R In a welding process for producing a thin walled longitudinally seamed tube by generating an arc between confronting edges of formed strip stock T at a welding station W and urging the edges together by at least three squeeze rolls S, continuous measurements are made of the pressures applied by the rolls S, of the speed of the strip stock, of eddy currents produced in the welded tube, and of three electrical factors relating to the supply of high frequency electrical power to the arc, and when any one or more of the measured values deviates by a preset amount from values previously determined as producing satisfactory seam welds the particular section of welded tube is identified for subsequent rejection. The welding station is preferably followed by a shearing station at which the welded tube is cut into predetermined lengths and the electrical circuitry is arranged to ensure that a gate is opened to allow the rejection of a substandard section of pipe identified previously by the measurements made in the welding process. Measurements indicating a substandard weld may also be used to actuate physical marking of the tube length by tube marking pens. An additional parameter of the process which may be monitored and used to identify sections of welded tube requiring rejection is the location of and light intensity emitted by the welding are. An impeder is located within the tube stock at the welding station to concentrate the high frequency welding current at the edges of the stock and a controlled flow of coolant serves to maintain the impeder at a constant temperature as a further condition for producing satisfactory weld seams. The three electrical factors which are measured to provide parameters of the arc power supply are the voltage and current on plates of rectifier tubes in the welding apparatus and the current in grid circuits of oscillator tubes therein.

Abstract: 1287914 Colour facsimile RCA CORPORATION 19 Sept 1969 [26 Sept 1968] 46316/69 Heading H4F In colour facsimile apparatus laser beams are used to both scan the original in three spectral colours, and to scan a photographic film. record for each colour separation. The recording laser beam may be pulsed to produce half-tone separation images directly. The colour transparency original 14, Fig. 1; and the high gamma recording film 18 are mounted on glass cylinders 12 and 16 respectively, rotated by motor 20 and advanced axially by drive means 24. The stationary laser beams thus scan the respective original and film in a raster scan. An argon laser 26 emits a beam 32 with discrete wavelengths 458, 476, 488 nm. (blue) and 514 nm. (green). A helium/neon laser 28 emits a beam 36 of wavelength 633 nm. (red). A combined beam 41 is produced by mirror 40 to scan the original in three colours. Interference filters 44 and 48 separate out the blue and the green components respectively in the beam after it passes through the original, which components fall on respective solar cell detectors 46 and 50. The remaining red component falls on solar cell detector 52. The "red", "green" and "blue" signals are converted in computer 53 to yellow, magenta and cyan signals which appear at respective terminals Y, M and C. A manual switch 56 selects which colour signal is to be fed to the recording means-yellow is shown selected. Laser 26 also produces a beam 34 which passes to scan the recording film 18 via an electro optical modulator 62 controlled by the output of amplifier 58. With switch 60 in its shown, lower, position the output, and thus the recording, is continuous. Very close marks 70 around the glass cylinder 12 interrupt the laser light and cause photo-cell 72 to give a pulsed output. These pass via counter 74 to an AND gate 82. A single mark 76 causes photo-cell 78 and counter 80 to enable gate 82 on every fourth line such that, on every fourth recorded line, and with switch 60 is its upper position, the output of amplifier 50 is raised through gate 86 in a series of pulses amplitude modulated pulses. These are applied to the modulation 62 to cause amplitude pulse modulation of the laser beam and the half-tone recording. A krypton laser, emitting light in the red, blue and green spectral regions may be used instead of 26 and 28.
