Title: Isometric imaging system
IPC: G01N21/88
Filed: 1973-05-07
Abstract: 1426388 Analogue calculating circuits UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 7 May 1973 [24 May 1972] 21623/73 Heading G4G [Also in Divisions H3-H5] In a system for imaging an object by scanning a wave-energy transmit/receive transducer to obtain reflection signals from the object (see Division H4), voltages representing the coordinates of the transducer in two dimensions plus time-of-flight data for the reflection signals are processed by analogue means which provide co-ordinate transformation to give an isometric projection representation of the object. Where the transducer co-ordinates and time of flight data represent a space with co-ordinate axes X, Y, Z, the transformation gives isometric projection co-ordinates X<SP>1</SP>, Y<SP>1</SP> as follows where 0 and # determine the "angle of view" of the object. The analogue means include sine/ cosine potentiometers, op-amps used as unitygain inverters, and multiplying circuits.

Abstract: 1455203 Centrifugal classifiers UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 16 May 1974 [6 June 1973] 21711/74 Heading B2P A method of classifying particles suspended in a liquid into two portions having different settling velocities in the suspending liquid comprises the steps of: continuously introducing a sample comprising the particles and suspending liquid into an enclosed rotating right toroidal cavity at a point intermediate the centrifugal and centripetal sides of the cavity; flowing suspending liquid from adjacent the centrifugal side of the cavity towards its centripetal side at a velocity which is intermediate the settling velocities of the two portions of particles, whereby the faster settling portion of particles moves in the centrifugal direction and the slower settling portion moves in the centripetal direction along with the flowing liquid; removing the faster settling particles and suspending liquid from adjacent the centrifugal side of the cavity and removing the slower settling particles and suspending liquid from adjacent the centripetal side of the cavity. As shown in Fig. 1, the rotor of an elutriator has an enclosed toroidal cavity 6 into which open conduit means 7 for suspending liquid, conduit means 8 for removal of slower settling particles and suspending particles, conduit means 10 for introducing a sample of particles suspended in liquid and conduit means 9 for removal of the faster settling particles and suspending liquid. The conduit means may each consist of equally spaced pipe-like passages or of a disc-shaped cavity extending from the rotor housing exterior. Baffles 2, 4 pervious to suspending liquid and particles are located in the cavity to provide uniform flow therethrough and may be in the form of wire mesh, perforated sheet, porous PTFE or of a packed bed of beads. The rotor may consist of peripherally bolted, vertically stacked plates of stainless steel which may be coated with PTFE. In a modification, Fig. 2, the baffle 2' extends only partially across the cavity and a partition 13 extends between the top of the baffle and the centrifugal side of the cavity to provide a flow path for suspending liquid flowing from the conduit means 7 through the baffle 2'. The conduit means 9' in this case is located nearer the centrifugal side of the cavity.

A process for recovering nitrogen oxides in the form of an acid aqueous solution of ammonium nitrate from waste gases (which may include NO, NO 2 , N 2 O 3  and N 2 O 4 ) comprises initially adjusting the molar ratio between NO 2  and NO to about 1, then scrubbing the gas mixture with aqueous ammoniacal ammonium nitrate solution in a gas-scrubbing plant, the NH 4 OH content of this solution being such that the H 2 O : NH 3  weight ratio in the vapour phase above it is from 2 : 1 to 100 : 1, and finally reacting the NH 4 NO 2 /NH 4 NO 3  solution thus obtained with a solution of ammonium nitrate containing nitric acid. The scrubbing solution may contain 40-50 wt. per cent NH 4 NO 3  when the operating temperature is 20-30‹ C., and its NH 4 OH content is preferably such that the scrubbing plant effluent contains 0À05-0À5 wt. per cent NH 4 OH. The amount of washing solution may be so metered that the effluent contains 0À5-5 wt. per cent NH 4 NO 2 . The scrubbing may take place in a number of washing stages which are preferably arranged in series with respect to the gas flow and either in series or in parallel with respect to the scrubbing solution flow. The NO 2  : NO ratio of the gas may be readjusted to about 1 after it has traversed half or two thirds of the washing stages. In addition, three subsequent washing stages may be provided in series with respect to the gas flow, the first employing the effluent from the third (final) stage, the second employing NH 4 NO 3 /HNO 3  solution, and the third employing water. The reaction between the scrubbing plant effluent and the NH 4 NO 2 /HNO 3  solution may take place at 10-30‹ C., the latter solution preferably being used in an amount of 25 kg. thereof per kg. of NH 4 NO 2  in the effluent. The ammonium nitrate solution produced may in part be recycled to the scrubbing plant.
