Title: Method and apparatus for the separation of isotopes
IPC: H01J49/16
Filed: 1973-10-24
Abstract: 1440139 Particle separators JERSEY NUCLEAR-AVCO ISOTOPES Inc 24 Oct 1973 [2 Feb 1973] 49415/73 Heading H1D In a method of separating isotopes using selective photo-ionization, a flowing plasma containing ions of the desired isotopes is given energy to raise the electrons to an energy level higher than the thermal energy level of the plasma thereby causing expansion of the electrons and the desired isotope ions which are thus deflected from the general flow direction and can be collected. In Fig. 3, uranium 72 is vaporized by an electron beam and is irradiated by laser radiation to produce isotopically selective electron transitions in a manner known per se. The resulting plasma is formed into a beam 88 and in the region of collector plates 92 is given the additional energy referred to above with a resultant expansion of the desired ions in a transverse direction causing the isotope to collect at 96, the other components of the plasma passing to a plate 100. The additional energy can be from a laser, an electric field between alternate plates 92, an oscillating magnetic field high frequency radiation, e.g. microwaves or electrons.

Abstract: 1452273 Measuring the thickness of a web coating: measuring conductance KODAK Ltd 1 Oct 1973 [26 Oct 1972] 49424/72 Headings G1N and G1U The conductance, and hence the average thickness, of a coating 13, Fig. I, on a web 12 is  measured by positioning two electrodes 11, 11 adjacent to the coating, thereby forming with the portions of the coating 13 immediately opposite the electrodes two air-dielectric capacitors, which are connected together by the portion of the coating between the two electrodes, by applying a squarewave voltage pulse, Fig. 2a, between the electrodes, and by measuring the peak current that flows. Current will, of course, only flow, as shown in Fig. 2b, at the edges of the voltage pulse, and in the preferred embodiment the first current pulse x is gated to a peak follower and the second y is utilised to reset the peak follower, thereby producing a pulse, Fig. 2d, whose height is proportional to the conductance - and hence average thickness - of the coating 13. The arrangement is particu-  larly useful for measuring the thickness of a coating on a moving web. A plurality of electrodes are arranged in a row transversely to the direction of movement of the web Fig. 3, (not shown) and switching circuitry is provided whereby voltage pulses are sequentially applied between each adjacent pair of electrodes. This results in a sequence of pulses, like that of Fig. 2d, which may, for example, be displayed on an oscilloscope, to provide a simple indication of coating thickness and its variation  across the web.

Title: Improvements in or relating to ultrasonic measuring apparatus
IPC: G01S15/10
Filed: 1965-11-23
Abstract: 1,129,655. Echo sounding. REALISATIONS ULTRASONIQUES. 23 Nov., 1965 [25 Nov., 1964], No. 49741/65. Heading H4D. In an ultrasonic pulse-echo sounding system in which a range indication is derived from a signal whose amplitude is proportional to the time interval between two successive echo pulses, the display or recording of perturbations in the range indication is prevented. In the embodiment of Fig. 3, the diameter of a tube 4 moved relative to a transmitting/receiving transducer 2 is determined from the time interval between two successive echoes received from the lower part of the tube inner wall in a single measurement cycle. A device 7 provides a gating pulse bracketing the first of the two echoes and gates amplifier 8 to pass the first echo and trigger a square-pulse-generator 9. The voltage level attained by a ramp generator 11 in the interval between the two echoes appears on a capacitor 12 and is sampled, prior to the transmission of an acoustic pulse, when the trailing edge of a pulse from generator 9 renders diodes 15 to 18 conductive, thereby applying a voltage pulse through cathodefollower 22 to a storage capacitor 20. Capacitor 20 is coupled through an amplifier 21 to an electrochemical chart recorder 10. In the absence of echo pulses (e.g. due to irregularities on the tube surface or disturbances of the acoustic propagation) diodes 15 to 18 prevent changes in the voltage on capacitor 20.

Abstract: 1,204,019. Spreading implements. C. VAN DER LELY N.V. 28 Oct., 1968 [3 Nov., 1967], No. 51105/68. Heading A1D. A spreading implement e.g. for manure has an inlet port 18 with a remotely controlled mechanism to couple the port to a delivery pipe of a storage tank and a closure member 19 near the mouth of the inlet port 18. The implement has an outlet port 47 with a closure member 60, the two closure members 19, 60 being actuated independently by the same control member 21. To fill tank 7 a delivery pipe of a storage tank is positioned in a capturing basket 44. Lever 75 is moved to engage a pin 77 in a hole 71 of a limb 70, downward movement of the lever actuates linkage 20 to open closure member 19. A control valve (41) Fig 1 (not shown) is then operated to cause an assembly 38 to move a support ring 22 in the direction A. Arms 25 are thus pulled through an annular stop 30 causing them to turn inwardly and clamp on the delivery pipe and press it into fluid-tight engagement with the inlet port 18. Filling of the tank is by suction with a float control controlling the level obtained. After filling reverse movement of the support ring 22 releases the delivery pipe with the stop 30 ensuring positive movement of the arms 25. Closure element 19 meanwhile has been shut by moving arm 75 to its central position where it tends to remain under the action of springs 76. When the implement is required for spreading closure element 60 is opened by arm 75 engaging arm 69 with pin 77 and then being moved downwards to actuate linkage 61. Spreading member 58 is now opened by moving slide 59 upward. The liquid manure is forced out under pressure by a pump (8). A manhole 48 has a cover 49 connected by pivots affording two relatively spaced parallel ones with one of the axis being within the circumference of the cover, see Fig. 5 (not shown).
