Filed: 1974-12-21
Abstract: 1529679 Transistor switching circuits SIMMS GROUP RESEARCH & DEVELOPMENT Ltd 8 Dec 1975 [21 Dec 1974] 55338/74 Heading H3T [Also in Division H2] A circuit for supplying power to a load 13 such as the field winding of a motor, comprises a switching element 14 connected in series with the load and a primary winding 17 of a transformer 16 across D.C. supply terminals 10, 11, the secondary winding 18 of the transformer being connected to the terminals via a diode 19 which conducts when the flux in the transformer core collapses. The circuit protects the switching element which may be a transistor and also minimizes power loss in the switching element. When the switching element is turned on, the voltage induced in the secondary winding reverse biases the diode 19 and the winding 17 therefore acts as a choke to limit the rate of increase of current. On turning off the switching element 14 the flux in the transformer core collapses and the diode 19 is forward biased to return energy to the supply. A capacitor 21 and a diode 22 are connected in parallel with the switching element 14, the capacitor being charged when the switching element is turned off and discharged through the primary winding 24 of a transformer 23 and a further switching element 27 when the switching elements are turned on. When the switching element 27 is turned off, the energy stored in the transformer core is returned to the supply via a diode 26.

In an apparatus for cleaning waste gases containing sulphur compounds, e.g. waste gases from coal- or oil-fired boilers, the gases enter through inlet 7 a zone 3 containing an electrostatic precipitator and then a cooling and scrubbing zone 4, finally passing to remove sulphur compounds in parallel through beds 13 of a catalyst irrigated with liquid and are discharged through an outlet 15. The catalyst beds suitably consist of actiwater-carbon and may be supplied with water or sulphuric acid. Liquid from the catalyst beds is collected in a sump in the base of the apparatus and the common gas inlet duct 2" to the catalyst beds is made progressively wider in an upwards direction to equalise the flow of gas through the individual beds. The electrostatic precipitator may be omitted or follow the scrubbing zone, and the scrubbing zone may be in the form of a packed scrubber, a venturi-scrubber or a bubble-tray scrubber. In a modification the scrubbing zone is arranged externally of the main body of the apparatus but having a common wall therewith.

Abstract: 1442792 Sample cells AUTOCHEM INSTRUMENT AB 11 Dec 1973 [20 Dec 1972] 57318/73 Heading G2J A sample cell unit for photometric testing of liquids comprises one or more sample cells 8, 10 which communicate with an input pipette 3 and an output capillary tube 14, the tube 14 opening into an exhaust chamber 15 to which is applied a first sub-pressure to draw a sample from a test tube 2 into the sample cells and a greater sub-pressure in order to draw liquid from the sample cells into the chamber 15 and thence to a drain hole 12. The sample cells are defined by diametrical bores through a cylindrical body 5 housed within a transparent tube 6. The first sub-pressure applied to the chamber 15 is sufficient to draw liquid through the sample cells and a chamber 13 into the capillary tube 14. Any impurities in the sample cells are thus washed away by liquid which passes into the chamber 13 before tests are carried out. As shown in Fig. 1 the tube 14 extends into an inverted funnel 36 which may be dampened with a foamquenching liquid if the sample under investigation generates foam. Bundles of optical fibres 23, 24, 27, 28 transmit light from a source through the cells 8, 10 to recording means such as photo-cells. Fluorescent measurements of a sample may be obtained by recording light directed from the sample along a light guide which extends at right angles from the centre of each sample cell.

As shown in Fig. 1, the inlet 14 and outlet 19 are apertures at the extremeties of ducts 13, 18 respectively within the wall of the guide tube 10, duct 13 being connected via a pipe 17 to a doser 16 for the inert gas and duct 18 being connected via a pipe 20 to a means 21 for measuring the radioactivity in the gas. The guide tube 10 is mounted eccentrically within a rotatable plug 2 which is in turn mounted eccentrically within a rotatable plug 3 and, by means of these plugs 2, 3, the guide tube 10 is positioned over the stack 6 to be tested and lowered by means of a drive 9. The guide tube 10 accommodates a rod 11 with a gripper 12 which grips the cap of the stack 6 and, as the rod 11 is moved up, the stack 6 is introduced into the tube 10. Inert gas from the doser 16 is bubbled through the coolant within the tube 10 to entrain the radioactive gases from any leaky fuel elements of the stack 6. The presence of such gases is detected by the measuring means 21. In a second embodiment (Fig. 2, not shown), a downwardly spun tube located within the guide tube is lowered over an upper portion of a fuel element stack, the lower end of the open tube being adapted to seal against the upper end of the stack. By this means the step of introducing the stack into the tube for the detection of leaky fuel elements is avoided and a stack is only removed from the reactor core by means of the recharging mechanism if a leaky fuel element is detected.

Filed: 1971-12-18
Abstract: 1372735 Thermal regenerators R N PENNY 14 Dec 1972 [18 Dec 1971] 58901/71 Heading F4K Leakage fluid flow through a seal at the end face of rotary disc type matrix in a thermal regenerator is maintained at a desired value by controlling the application of a pressurizing fluid to the seal, the seal being in the form of a closed loop defining at the matrix end face regions through which the separated streams of heat exchanging fluids are to be passed. Preferably the leakage fluid 16 passes to a fluid-responsive device which regulates the application of pressurizing fluid to the seal. The pressurizing fluid may be one of the heat exchanging fluids (e.g. compressed air and turbine exhaust gases) or it may be a separate fluid. The fluid-responsive device may as shown comprise a valve 13, a fluidics switching device (Fig. 3) or it may be a pressure transducer to which the leakage fluid is applied and which operates electrical means for supplying or withdrawing pressurizing fluid to or from the seal.  In the arrangement shown, the seal 5 incorporates a bellows 11 which is internally pressurized by the pressurizing fluid to urge the seal 5 towards the matrix 1, and the latter axially against the seal 6. Leakage fluid 16 acts on the end of valve piston 19 against the action of valve spring 22. In use, an excess of leakage fluid depresses piston 19, thereby admitting H.P. air (from heat exchange fluid stream 7, 9) via ducts 14, 12 to bellows 11 to thereby apply more sealing pressure and reduce leakage. When leakage fluid flow 16 has reduced sufficiently the resulting fall in pressure above piston 19 allows it to rise under the influence of spring 22 so permitting fluid from bellows 11 to discharge via ducts 12, 15, thereby reducing the sealing pressure and allowing increased leakage flow.
