Abstract: 705,299. Fluid flowmeters. TEDDINGTON CONTROLS, Ltd. Aug. 20, 1952 [July 2, 1951], No. 15681/51. Class 97(2) [Also in Group XXIX] A fluid flowmeter comprises a plurality of discs, each operating in its own tapered conduit and coupled to a shaft which is connected to an indicating and/or recording instrument, the discs consisting of one or more pairs so mounted that the discs of each pair move in an opposite sense under variations of fluid flow, whilst the application of an external force, e.g. the effect of acceleration of an aircraft carrying the flowmeter, balances out on the discs and imparts no movement to the shaft. In the form shown, a pair of tapered conduits 2a communicate with an inlet pipe 1 and each contains a movable disc 6 connected by rods 3, 7 to an indicating shaft 4 biased by a spiral spring 9. Alternatively the discs 6 may each be biased by a helical spring. The conduits 2a lead to a common manifold 5 and more than one pair of conduits and discs may be fitted. The movement of the shaft 4 may be transmitted to the exterior of the meter via a magnetic coupling and a variable inductance, moved by the slave magnet, may cause a current change in an electric circuit which is measured directly to indicate the rate of flow and, integrated by a " watt-hour " type meter, to indicate total flow.

Title: Method of separating at least one component of an isotope mixture
IPC: B01D59/34
Filed: 1976-04-15
Abstract: 1512873 Producing selective excitation by means of electromagnetic radiation KRAFTWERK UNION AG 15 April 1976 [18 April 1975] 15718/76 Heading G6P Isotope separation embodies selective excitation to saturation of molecules of one isotopic type by irradiation of an isotope mixture with pulsed or continuous e.m. radiation whose frequency lies within a zone of the rotationvibration spectrum of the mixture in which the density of spectral lines is considerably higher than in other zones and in which the numbers of molecules of the different isotopes differ. The high-density zone will usually be the Q branch of the spectrum, the mean frequency lying in the visible, U.V. or I.R. The e.m. radiation is provided by a laser; its intensity is selected so that of all the molecules having absorption frequencies in the zone, only those of a selected isotope reach saturation (i.e. half the absorbing molecules are raised to an excited state). If the laser is pulsed, its period must be less than the rotation relaxation time of the excited molecules. If the laser operates continuously, separation of the excited molecules by a chemical and/or physical technique must be effected in less than the rotation relaxation time. Separation of uranium isotopes by the selective excitation method is described in detail. Separation of C<SP>12</SP> and C<SP>13</SP> by irradiating methane is also mentioned.
