The first catalyst is a platinium gauge or palladium or platinium on a support. The second catalyst is a base metal, i.e. nickel or cobalt and may also contain copper. Alternatively the second catalyst may be ruthenium. The volume of the first catalyst is 0.02 to 0.2 times the volume of the second catalyst when both are in the same physical form. The space velocity over the first catalyst is 0.15 to 3.0 x 10<SP>6</SP> hour <SP>-1</SP> and the velocity over the second catalyst is 0.15 to 3.0 x 10<SP>5</SP> hour <SP>-1</SP>. A third treatment stage involving the addition of air and catalytic oxidation may be provided. The reaction temperature in the second stage is over 700‹C e.g. 800-950‹C when a base metal catalyst is used and is 300-700‹C e.g. 300- 500‹C when a precious metal catalyst is used. The first stage catalyst is operated at 400-1000‹C depending on the temperature required at the inlet to the second stage. The oxygen content of the gas entering the first stage is typically 0.5% and this is preferably reduced to less than 0.15%: Catalysts The oxidation catalyst can also be a metallic oxide or oxide mixture selected from the transition metals such as copper, titanium, tin, lead, phosphorus, bismuth, vanadium, niobium, tantalum, chromium, tungsten, manganese and rhenium. Preferably it contains a metal or alloy from Group VIII of the Periodic Table e.g. rhodium, palladium or platinum. The support may be highly calcined magnesia, alumina, mullite. spinel, zirconia, zirconium silicate, hafnia or thoria and may be combined with a low-silica hydraulic cement. The catalytic material is suitably supported on calcined clay/cement granules.

IPC: G01P13/02
Filed: 1974-03-28
Abstract: 1465811 Flowmeters FURUKAWA ELECTRIC CO Ltd 28 March 1974 [6 Nov 1973] 13883/74 Heading G1N Apparatus responsive to flow-rate in fluid of poor electrical conductivity comprises two chambers for receiving the fluid the chambers being aligned in the direction of flow in a conduit; a source of ionizing radiation; two pairs of spaced electrodes constituting with the chambers a transducer and defining respective ionizing areas therein; shield means; and an amplifier of high input impedance and low output impedance disposed within the shield means and connected to the electrodes. A gas flowmeter 10, Fig. 1, includes a transducer 20 comprising a conduit 200 of PVC sections 202-208 locating between them three spaced electrodes 210-214 of wire gauze. Alpha-particle sources 222, 224 e.g. americium, secured to the common electrode 212, ionize the gas in the areas 216, 218 defined between the electrodes so that, if the gas is flowing, the ion concentration, therefore the conductance, in the downstream area exceeds that upstream. An FET 300, e.g. enhancement MOSFET,  mounted adjacent the conduit 200, has its gate connected to the common electrode 212 and its source and drain respectively to the outer electrodes 210, 214 and to external leads 308, 310 between which a D.C. resistance representing the relative conductances of the areas 216. 218 is measurable. A metallic shield 402, 404a, 404'a, either above or enclosed within a PVC case 400, 404, 404', excludes electrical noise from the high-impedance circuits within. A circuit 53, Fig. 5, for indicating fluid -flow in one direction comprises a Schmitt trigger 500 having an adjustable threshold, and an output circuit 506 for closing relay contacts 508a, 508b. A similar circuit Fig. 6 (not shown) indicates the cessation of fluid-flow. A detector for liquids, Fig. 8 comprises a rectangular conduit 226 having opposed plane electrodes 228-234 flush with the walls and defining a clear passage. Alternatively Fig. 9 (not shown), two aligned hollow cylindrical electrodes (240, 242) flush with a conduit wall (238) are opposed to a common axial rod electrode (244) supported in insulative frames (241, 243). For measurements on electrolytes the two ionizing areas are arranged in the arms of a Wheatstone bridge Fig. 7 (not shown) connected to the FET input and supplied with voltage below the electrolytic threshold. Temperature compensation may be provided Fig. 10 (not shown) by mounting the FET (300) in the conduit (202) but outside the ionizing area, so that it is immersed in the fluid.

IPC: G01S1/72
Filed: 1929-05-04
Abstract: 316,863. Electroacustic Ges. Aug. 4, 1928, [Convention date]. Locating sounds.-Relates to apparatus for determining the direction of sounds by the interference method and consists in interposing between the receiving and listening devices fixed filters which eliminate the results of those frequencies occurring in the arriving sound or arising in the receivers themselves which would give rise to a secondary maximum in the listening device. The invention is applicable both to apparatus having fixed receivers with electric or acoustic compensators and to apparatus having rotatable groups of receivers. The filters may be electrical or mechanical, and may eliminate waves having a wave-length approximately equal to or less than double the distance between the receivers. In the examples shown, the filters 5 - - 8 are connected between the receivers 1 - - 4 and the electric compensator 9, 10. As an alternative, one filter only may be connected between the contact 12 which slides over the compensator contacts 13 - - 18 and the telephone 11. The fixed filters may also be used for eliminating receiver harmonics, in which case they eliminate waves of a frequency equal to or less than that of the first harmonic of the receiver. In a particular application to subaqueous sound reception, the receivers are spaced approximately 75 cms. apart and the filters eliminate waves of a frequency up to 1000 cycles per second.

Title: Brakes for rail vehicles
IPC: B61H13/02
Filed: 1933-05-13
Abstract: 419,729. Transmitting mechanism for brakes. MALEY, A. W., 4, Grosvenor Road, Handsworth, and TAUNTON, E. M., 90, Fitz Roy Avenue, Harborne, both in Birmingham. May 13, 1933, Nos. 13977/33 and 17392/34. [Class 103 (i).] In order that the tension or compression of the pull-off springs for the brake shoes of railway vehicles may not be affected by the adjustment of the shoes to compensate for wear, the springs are connected between parts that are not shifted relatively by the adjustment for wear. Fig. 1 shows mechanism of the kind described in Specification 396,694 comprising pull-rods 1 connected together and to the operating rod 17 by equalizing mechanism 18 and each connected to a brake beam 3 by an adjusting nut 6. The pull-off spring 7 instead of being connected to the brake shoe or to the beam 3 is attached to a collar 12 secured to the rod 1, the other end being attached to a frame member 8. Fig. 4 shows mechanism comprising a brake beam 25 and an equalizer beam 22 interconnected by an operating lever 34 and brake rods 19 extending from the beam 22 to the other end of the truck. In this case, the pull-off springs 23 connected at one end to the beam 25 are attached at the other end to a yoke 31 that bears upon a nut 33 on a fixed bolt 28. The nut 33 telescopes on to the adjusting nut 20 of the rod 19 and the nuts are of non-circular cross-section so that rotation of the nut 20 to adjust the brake rod 19 in relation to the beam 22 is necessarily accompanied by rotation of the nut 33 and leaves the springs 23 unaffected. The bolt 28 instead of being in line with the rod 19 may be offset, the two nuts being arranged side by side and provided with intermeshing pinions.

Title: Programming apparatus for a machine tool
IPC: B23Q16/00
Filed: 1958-05-01
Abstract: 893,795. Drilling. FOSDICK MACHINE TOOL CO. May 1, 1958 [May 1, 1957], No. 13987/58. Class 83 (3). [Also in Groups XXIV and XXXVIII] Apparatus for setting a machine element 15 in a position determined by recorded data, e.g. on punched cards or tape, comprises means responsive to an electric signal for selecting measuring elements 28, 30, 31, corresponding to a dimension required and for mechanically moving the elements to determine the position of the element. In a jig-boring machine having a table and slide both automatically positioned by similar means, the measuring elements for the table are carried in rotary containers and on rocker arms and the selected elements are moved into line with one another as described in Specification 831,654. Thus, as the table 15, Fig. 26, is moved to a desired position, the selected ten-inch rods 30, the inch rod 31, and the decimal rods 28 are positioned between a rod 35 on the table and a feeler rod 33 mounted on the slide 13. When a cycle-start switch is pressed, the table is first moved to the left until a selected one of a number of back-off switches 60-63 is actuated by the table. This backing-off movement allows the selected measuring elements to be moved into position. Whereas, in the previous Specification, the rods were selected by setting dials rotated by hand, in the present machine the dials 24 each carry a gear which can be rotated by a motor 186 according to the setting of solenoid-operated clutches. Moreover, gears rotated with the dials each carry a brush which sweeps a circle of studs which can be selectively energized by the programme to determine the set position of each dial. These stud circles are shown in Fig. 26 connected to the programme reader. When a brush reaches an energized stud selected by the reader, the associated clutch is disengaged and the dial comes to rest. When a positioning switch 57 is depressed the table is traversed by a motor 36 through a screw 18 engaging a nut 38. Near the required position, the motor 36 is stopped by a switch operated by the feeler rod 33 and a motor 37 is started to rotate the nut 38 through gearing 41 to move the table slowly to the final position. The motor 37 is then momentarily reversed to relieve the driving stress. As illustrated, the table 15 is then set at a position 37.9625 inches from a previously set reference. This reading is indicated visually on the dials 24. The programming circuits may be interconnected with the drill head motor to initiate the drilling operation at required rotational and feed speeds. A manual stop switch 278 stops the whole machine in an emergency. A manual switch 281 allows the dials to be set by hand. U.S.A. Specification 2,674,706 also is referred to.

Filed: 1935-05-13
Abstract: 451,716. Protective arrangements ; automatic regulators. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and DONNELLY, W., 7, Albion Avenue, Park Drive, Blackpool. May 13, 1935, No. 13999. [Class 38 (iv)] The load circuit of a high voltage low power system such as electrostatic precipitation plant 3 is protected by the series connection of a device 2 having a resistance increasing with current, e.g. a barretter connected in parallel with a device 1 which conducts only above a critical P.D., e.g., a discharge tube or spark gap. The operating coil 4 of a retarded relay controlling the supply circuits may be included in series in the load circuit and the arrangement is such that the barretter takes up momentary fluctuations in voltage and tends to limit the voltage across the load on flash-over. If the current rises e.g. a short circuit, to a value such that the P.D. across the barretter increases above the critical value for the discharge device 1, this conducts and effects a further limitation of the voltage across the load, and, in the event of the fault persisting the coil 4, operates to interrupt the supply. A limiting resistance 5 may be connected in series with the discharge tube 1.

Abstract: 407,561. Prepayment mechanism for meters. METERS, Ltd., Blackfriars House, Parsonage, and BARLOW, G., 171, Windsor Road, Oldham, both in Lancashire. May 15, 1933, No. 14030. [Class 27.] Coin action, thrust and multiplecoin.-In a prepayment mechanism for gas or like meters operable at will by pennies or shillings, a coin inserted through a slot in the usual price-change disc a<1>, Fig. 1, into a pocket b which is rotated by a handle b<x>, depresses a slide b' by acting on an arm b' and causes a tooth b<3> to engage the teeth of a wheel c. The wheel c has a hollow boss c<1> on which is secured a wheel c<2> meshing with a wheel c<3>, Fig. 7, on a short shaft carrying another wheel c', which drives a wheel e either through wheels e<1>, e<2>, Fig. 4, or through wheel e<3>, e<4>. Rotation of the shaft of the wheel e is transmitted through bevel wheels g, g<1> to a usual screw-and-nut valve-controlling quantity mechanism. The wheels e, e<2> are compounded for rotation together as also are the wheels e<3>, e<4>, the wheels e', e<3> being mounted in a frame f which is rockable about the axis of the wheel e to cause either the wheel e<1> or the wheel e<3> to mesh with the wheel c' according as a shilling or a penny is used. Normally the frame is held by a spring h with the shilling wheel e<1> in mesh. When a penny is inserted, an incline b<5> on the arm b<4> shifts a plunger p, passing through the boss c<1>, rearwardly. The outer end of this plunger acts on an incline or cam-face f<1> fixed on the frame f and rocks the frame to disengage the wheels e<1>, c<4> and bring the wheels e', c<4> into engagement. If a coin, such as a halfpenny, is inserted the frame f is only rocked so far that neither wheel e<1> or e<3> is in mesh with the wheel c<4>.
