Abstract: 1449625 Activated sludge process J R KAELIN 2 Nov 1973 [23 Aug 1973] 50966/73 Heading C1C In the treatment of effluent with oxygen or oxygen-enriched air and activated sludge in sealed tanks, the roles of the oxgyenation and settling tanks are periodically alternated by reversing the direction of flow through the system. In Fig. 2, effluent enters at 3<SP>1</SP>a into tank 4a where it is oxygenated and circulated by turbine 5a supplied with oxygen or oxygen-enriched air from pipes 7. The resulting effluent/sludge mixture passes through orifice 10 into tank 4b where turbine 5b is stationary, clarified effluent leaves at 8b and excess sludge at 13. When the sludge concentration in 4a becomes too low, turbine 5a is shut down, outlet 8b is closed, outlet 8a is opened, turbine 5b is started and supplied with oxygen or oxygen-enriched air, and effluent is instead fed to tank 4b, oxygenated therein, settled in tank 4a, clarified effluent leaving at 8a. The tanks are each equipped with cross-shaped baffles 15. and hot-water heaters 30. The process is monitored and controlled by photocells 12 andoxygen metering probes 23. In Fig. 1 (not shown) a plurality of such double-tank units are operated in parallel. In Fig. 3. (not shown) a single surface aerator is periodically moved from one. tank to the other.

Title: Methods of estimating one radioactive substance in the presence of another
IPC: G21C17/07
Filed: 1975-11-25
Abstract: 1499113 Testing nuclear reactor fuel elements UNITED KINGDOM ATOMIC ENERGY AUTHORITY 25 Nov 1975 [26 Nov 1974] 51208/74 Heading G1A. A method of leak-testing a nuclear reactor fuel element by determining the amount of radioactive gas in the plenum, which may also contain some radio-active fuel having an energy spectrum substantially overlapping that of the gas, comprises:- measuring the amounts of radiation over two ranges including (a) a substantial part of the gas spectrum and a major part of the fuel spectrum and (b) a substantial part of the gas spectrum and a minor part of the fuel spectrum; and calculating therefrom the amount of gas present. A known quantity of e.g. Kr-85 included in the plenum of a stainless-steel clad Pu-239 or  U-235 fuel element, enables leakage of the gas  from the cladding to be detected by measuring an abnormally low rate of emission of bremsstrahlung from the cladding due to irradiation by Kr-85 #-particles. To minimize measurement errors due to 7-rays emitted by fuel particles which may contaminate the plenum, radiation is measured over range A as illustrated, which contains about 2/3 of the bremsstrahlung due to the Kr-85 and most of the γ-rays due to fuel, and over range B which contains the remaining 1/3 of the bremsstrahlung and about 1/40 of the fuel radiation. A ratio substantially exceeding 2:1 between pulse counts in ranges A and B indicates the presence of fuel. Furthermore the quantity of Kr-85 present can be calculated by a formula derived by solving a pair of simultaneous equations, provided the respective ratios for Kr-85 alone and fuel alone have previously been determined.  Measurements may be made with a NaI scintillator masked with a lead collimator to view a portion of the plenum and applied to a photo-multiplier Energy ranges may be selected by choice of detector discriminator bias or by the use of a pulseheight analyzer.

Abstract: 1323379 Mechanical switches SWFSPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU GmbH 10 Nov 1971 [10 Nov 1970] 52119/71 Heading H1N A steering column switch for automotive vehicles has an operating lever, which by movement in a plane perpendicular to the column operates a switch device in the column for direction indication; by movement in a plane parallel to the column operates an optical or acoustic signal via a second switch device in the column; and by rotation of the lever operates a third column switch for operating, for example, head lights; the operating lever having a further switch mounted in the hand grip portion on the lever, operated by axial movement of the grip relative to the lever, said switch being arranged to actuate windscreen wipers. Figs. 1 and 2 illustrate the last mentioned switch, the grip 54 being movable axially with respect to the lever 52 against a return spring 33 and being retained thereon by collar 51. The contacts 60, 70 are operated by the asymmetric stepping wheel 59 mounted on a bearing axially slidable in the slot 63 which is fixed relative to the lever 52. The bearing is attached to the grip and moves therewith, the projection 62 or the contact spring causing the wheel to be "stepped" thus moving the spring contacts between fixed contacts on terminal strips. A further rocking switch 50 operates a third contact spring 68 between further strips (c.f. description of Specification). The arrangement of the terminal strips is such that operation of the grip causes the windscreen wiper motor to be actuated (or parked) and the rocking switch give either a fast or low wiping speed, c.f. circuit diagrams of Figs. 3 and 4 (not shown). The actuating lever of second switch and third switches, 78 and 85 respectively are shown in Fig. 5. Movement of the operating lever 51 around the pivot point 77 actuates the switch member 78 with projection 84. The operating lever which is rotatable within the housing 80, has a keyed collar 90 (91, Fig. 6) thereon of which a portion 94 contains a contact 87 being biased outwardly of the lever by spring 89 to abut flat contact portions 88 of terminals 86. The contact portion 87, Fig. 6, is spherical in shape and thus retains the switch in any "set" position between contact portions 88. The action of the switch is self cleaning.

Prefabricated building elements are cast in a tiltable mould which can be rotated from a horizontal to a vertical position for unloading. As shown, the apparatus comprises a transfer table 39 mounted on rails 49 for carrying the mould from moulding to unloading stations and a manipulator 31 for moving the mould transversely and tilting it at the unloading station. The mould 10 has a mesh base 18 through which water can be extracted by suction from pumps 18, vibrators 13, a removable side 16, on which the finished unit is removed from the mould and sealing blocks 19 to make the mould airtight when a further mesh with extracting means 22 is lowered on to and clamped to the mould. The element is cast with the surface that will form the outside at the bottom of the mould. A filler cloth is laid on the mesh base 18 and a layer of plaster 1 is applied thereto, the layer being levelled by movement of the mould assembly along the track 49 under a spreader. A layer of concrete 2 is laid on the plaster, a heat insulation insert and reinforcement 3 are laid on the plaster and the mould is vibrated. The evacuation system 12 may also be switched on to draw water out of the concrete. The mould is then filled level with its top by a layer of concrete 4. Vibration lowers the level of the concrete layer 4 and the mould is filled with a layer of "warm" plaster 5. A filter cloth is laid on the plaster surface, the mould is closed by upper section 28 and the mould is vibrated and suction applied to reduce the water content of the element. The upper section 28 and filter cloth are removed and the mould is filled with a second layer 6 of "warm" plaster 6. When the element has set sufficiently, the mould is carried by transfer table 39 to the storage bay and is moved transversely from the transfer table on the manipulator 31 from which the mould is tilted on to side 16 of the mould, this side being left as a stand for the element. This method of stacking allows the outer plaster surface 1 to be worked to any desired finish; the inner surface 6a butting against a previously moulded element.
