Abstract: 1,059,246. Fuelling reactors. SOC. ANGLOBELGE VULCAINS.A. May 6, 1965 [May 12, 1964], No. 19113/65. Heading G6C. To remove fuel elements from a heavy water cooled and/or moderated reactor, the heavy water is replaced by light water. During the liquid change, the fuel elements are cooled by gas when they are not being cooled by either of the two liquids. Heavy water from the pressure vessel 1 and auxiliaries above inlet-outlet level 4, 5 is removed and collected in an auxiliary tank which can be gas pressurized for emergency quick return of the heavy water to the pressure vessel. Gas fed to the pressure vessel forces the heavy water out of the pressure vessel via pipe 7. When the heavy water level reaches the bottom of thermal shield 3, a convection circulation of the pressurizing gas is established via the channel between the thermal shield 3 and the pressure vessel wall. When the heavy water has been drained, light water is admitted via pipe 9, after which the pressure vessel enclosure is flooded and the pressure vessel top closure removed. If necessary, some flow of coolant can be delivered to the fuel elements when they are only partially covered by liquid, e.g. by forcing gas through a pipe 8. In a second embodiment the reactor pressure vessel is emptied by gas at atmospheric pressure.

Filed: 1943-11-18
Abstract: 574,885. Spray evaporators. LEVERICK, F. Nov. 18, 1943, No. 19244. [Class 32] Apparatus for separating the more volatile components of a liquid mixture from the iess volatile components and comprising a preheater, spray discharge nozzles and a reduced pressure chamber is characterised in that the liquid passes from the preheater into a short steadying space terminating in a wall constituted as a nozzle plate. The liquid mixture is drawn by vacuum pump A into steam heated vessel F through gland E. It flows through radially disposed U- tubes G, during which it is heated to a temperature slightly less than the evaporation temperature of the most volatile constituent, and then passes to a small steadying space H, Fig. 32, which is bounded on one side by a nozzle plate h' through which the liquid is discharged as fine jets into the expansion chamber J where the pressure is less than that in the steadying space owing to the resistance of the nozzles. Evaporation of the more volatile constituents of the liquid takes place in chamber J and the vapours and unevaporated liquid so formed pass together through steam heated tubes k, where further evaporation takes place, into separation chamber M. Transverse tubes j pass through chamber J and these communicate with the steam vessel-F.

Title: Method and apparatus for non-destructive testing
IPC: G01N29/04
Filed: 1973-04-24
Abstract: 1421849 Ultrasonic inspection NATIONAL AERONAUTICS & SPACE ADMINISTRATION 24 April 1973 [20 April 1972] 19317/73 Heading H4D A method of non-destructive testing involves generating a succession of spark discharges between a pair of spaced electrodes adjacent a surface of a specimen, which discharges produce a narrow beam of acoustical energy which contacts the surface to induce propagation of acoustical energy in the specimen, which propagation is then detected. Pulse generator 40 produces a 2000 volt peak-to-peak pulse which is amplified by a toroidal powdered core transformer 42 to a 10,000 volt peak-to-peak pulse across secondary winding 46. The pulse has an initial negative portion followed by an equal positive excursion (Fig. 3, not shown). The pulse is fed via leads 48, 50 to connectors 28, 34 fitted to tungsten rods 24, 26 which fit into channels 12, 14 in a transparent acrylic block 10. The channels 12, 14 are essentially tubular but at the lower end have frusto-conical portions opening into a hemispherical chamber 16. This chamber opens out from the bottom surface of the block 10 and a rectangular channel 17 opens from the bottom edge of the chamber to the front of the block 10 (Fig. 2, not shown). The rods 24, 26 have conical tips such that when fitted into the channels 12, 14 the points are held at a fixed distance from each other in the chamber 16. When the generator 40 produces its high voltage pulses, spark discharges are formed in the chamber and ultrasonic energy caused by the collapse of the discharges is directed by the chamber 16 downward and projected forward along the channel 17 to produce surface waves on a test specimen (60, Fig. 3, not shown). A compressed air source is connected to the chamber 16 via tube 22, connector 20 fitting in a threaded recess 18 in the rear face of the block 10 and channel 19. While the transducer is operating, the air constantly purges any ionization products from the chamber 16 which might have been produced by the discharge. The effect of the surface ultrasonic waves on the specimen may be measured using a crystal transducer coupled via rubber thereto or by the effect on a laser beam reflected from the specimen surface (Fig. 4, not shown).
