Preferably the central reactor core is surrounded by four pods each containing a tube furnace 16 to provide four parallel flow paths for the reactor coolant, each of these pods being flanked by two further pods, one containing a steam generator 17 also heated by the reactor coolant and the other a heat exchanger 19. The flow paths of both the reactor coolant and process gas are arranged so that all hot components and ducts are surrounded by an envelope of cooler gas. Coolant flow path.-The hot coolant (helium) emerging at the bottom 5 of the reactor core 2 passes via the inner part of a coaxial duct 27 to a tube furnace 16 and then via the inner part of a further coaxial duct 34 to the corresponding steam generator 17. On reaching the bottom of the steam generator a blower 18 returns the cooled gas to the top 4 of the reactor core via annular channels 57, 58, 30 surrounding the steam generator, tube furnaces and core respectively and the outer parts of ducts 27, 34. A plate 31 seals off the upper part of the tube furnace pod, and the space formed is filled with helium under pressure. Process gas and steam flow paths.-Cold process gas (methane/water-vapour mixture) enters (47) a recuperative heat exchanger 19 from below and after partial heating therein passes via the outer part of the coaxial duct 38 to the tube furnace 16. The hot, cracked gas leaves the furnace via the inner part of duct 38, and after giving up some of its heat in the heat exchanger 19 leaves the pressure vessel via a coaxial duct 48, 51. Steam enters and leaves the steam generators 17 from above (53, 56).

Abstract: 1,253,508. Repeating dialled impulses. GNT AUTOMATIC A.S. 14 Sept., 1970 [19 Sept., 1969], No. 43802/70. Heading H4K. A transistor oscillator Q1 in shunt across a telephone line is switched into oscillation by each loop-disconnect impulse as detected by a resistor R3 in one leg of the line. The collectoremitter path of transistor Q1 shunts the legs La, Lb, of a loop between impulsing contacts 3 and feedbridge relay windings 1. The collector circuit is tuned by L1, C2, and feedback is provided by L2, C3, R2. Shunt capacitor C2 keeps A.C. off the line and Zener Z1 takes overvoltages. The closed and open loop condition is reflected in voltage across R3 which switches Q3 on and off accordingly so that oscillator Q1 is driven in response to each loop disconnection. Output in winding L3 switches transistor Q2 to repeat the impulses. The oscillator may be switched on and off by a diode shunt circuit round resistor R3 as an alternative to transistor Q3, Fig. 1, not shown. Oscillator current is limited by resistor R1 or by a constant current diode.

Title: Improvements in or relating to supporting devices for manually and vertically displaceable loads
IPC: A61B6/00
Filed: 1961-12-07
Abstract: 969,243. Piston packings. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 7, 1961 [Dec. 10, 1960], No. 43856/61. Heading F2T. [Also in Divisions B8 and H5] In a supporting device for, for example, -X ray apparatus, which allows the said apparatus to be manually displaced vertically, the weight of the apparatus is compensated for or " counterbalanced " by the difference in gas pressure on the two sides of a piston moving in a housing. Fig. 1 shows a piston 2 moving in a cylindrical housing 1, the guiding members 3, 4 not being air-tight. The X-ray apparatus or other load 7 is suspended from the lower end of the piston. The air-tight packing is provided by a rubber membrane 5 in the form of a tube, one end attached to the piston and the other (everted) end attached to the cylinder. In order that equilibrium may obtain in any position, instead of just one position, it is necessary that the difference in gas pressure is substantially independent of the position of the piston. In the arrangement of Fig. 1 this is achieved by creating a vacuum (through pump connection 6) on one side of the piston, the pressure on the other side being atmospheric. In the modification of Fig. 2 (not shown) two piston-like members, one telescoped inside the other, give a greater vertical displacement distance. In another modification (Fig. 5, not shown) the load rests on the piston, which is urged upwards by compressed air. In the further modification of Fig. 4, the cylinder 1 and piston 2 are arranged horizontally, and suspended on a carriage 22 which runs along a beam 23. The load 7 is suspended from a rope 14, the connection to piston 2 being made via a twin drum having two different diameters 24, 25. This differential arrangement gives a smaller piston displacement for a given load displacement. In the arrangement of Fig. 6, a gas-tight closure between cylinder 1 and piston 2 is formed by a rolling hollow rubber ring 30, which may be filled with liquid or a compressed gas.

Abstract: 1392169 Radiation responsive explosives detector WESTINGHOUSE ELECTRIC CORP 20 Sept 1973 [28 Sept 1972] 44066/73 Heading G1A The invention relates to detecting explosives e.g. in luggage by sensing the gamma rays emitted by nitrogenous substances subjected to thermal neutron flux. To discriminate from textile materials containing nitrogen, the disposition of the concentration of nitrogen is sensed by an array of detectors and the circuitry responds to an area and concentration corresponding to four sticks of dynamite, Fig. 5 (not shown). As shown the apparatus is arranged for investigating luggage passing on a conveyor C. The thermal neutron flux is provided preferably by moderating a fast neutron source 24 such as californuim 252 which may be encapsulated in a moderator 25 and as shown is also buried in the test-chamber-walls 22, which contain a moderating material such as water or paraffin. The gamma-ray detectors comprise scintillator/photo-multiplier units also mounted in the walls and arranged with two large units 26 for estimating the total nitrogen content, followed by rows of small detectors 28 for estimating the disposition. Since thermal neutrons liberate high-energy x-rays (10.8 MeV) from N-compounds the comparators to which the detector outputs are fed, pass on only signals in excess of 10MeV. These signals are then processed by a computor to determine the concentration profile, Fig. 2 (not shown).
