Abstract: 132,551. Jones, L. C., and Parsons, C. L. April 30, 1918. Catalytic apparatus; nitrogen oxide, catalytic production of by combustion of ammonia.- The oxidation of ammonia is effected without pre-heating of the gases, by means of a contact element in the form of a hollow laminated body of fine gauze constructed of or carrying catalytic material, arranged within a chamber having heat-reflecting inner walls. A strip of gauze is wound around an end piece 2 and spider 3 and secured in place by collars 4. The spider 3 forms the top of a cylinder 5 into which leads the gas inlet 9 through which passes a screwed rod 8 joined by a socket to a rod 7 for tightening the gauze laminations, the rod 7 being kept from rotating by a pin 10.

Abstract: 315,510. Lumb, A., and Lumb, L. May 7, 1928. Gas analysis. - Apparatus of the type described in Specification 23846/09 is provided with a pair of mushroom valves instead of the plug cock employed in the said apparatus for the automatic control of the gas to be analysed. The apparatus comprises a measuring chamber F connected, through an inlet passage. V, V<1>, controlled by a valve D in a casing A, to the source of gas to be heated. By the side of the valve E and opened simultaneously therewith by a comon actuating mechanism is a valve E which controls the passage of gas from the measuring bell G to the exterior atmosphere. The valves are actuated through a lever L by a bucket 3 which is filled by water passing from a tank down a pipe X into the measuring bell tank Y, thence to the vessel 1 which contains the measuring chamber F and thence through a syphon pipe 2. The bucket is emptied by a syphon 5. In operation the bucket 3 being full and valves D, E being open gas is drawn into the chamber F by the fall of pressure produced by the outlet of liquid from 'the vessel 1. The bucket 3 then empties and in consequence the lever L rises and the valves are closed. As water continues to pass into the vessel 1 the gas trapped in the measuring vessel is forced through pipes' V<1>, V<2> into an absorber 7 containing caustic potash solution and thence, through passages V<3>, into the measuring bell G which rises to a height indicated by a suitable indicating apparatus. When the water rises in the vessel 1 to a height sufficient to cause the syphon 2 to operate the water syphoning into the bucket 3 causes it to move the lever L to open the valves, and the cycle of operations is repeated. The outlet of the gases to the atmosphere is through the passage in the stem of the valve E.

[Classes 72 and 82 (i).] A process for reducing ores, for example iron ores, comprises mixing the ore with a solid carbonaceous material such as coke and passing the mixture through a rotary furnace wherein the ore is reduced by means of a gaseous, liquid, or solid reducing agent free from sulphur and ash, so that the coke &c. passes through the furnace substantially unchanged and acts to prevent sintering of the charge during the process. The reducing agent may be coal gas, water gas, producer gas, coke oven gas, oils, very finely divided wood charcoal, soot, or mixtures of these. In the apparatus shown, the charge is fed to an inclined rotary furnace 1 through an opening 8 and past a series of baffles 12, a similar arrangement of baffles 14 being provided at the discharge end. Reducing gas is admitted through a tube 16 and is burnt in a chamber 4 by means of air admitted through a tube 9. Excess of heat required may be supplied electrically by means of electrodes 18.

Abstract: 1308957 Measuring displacements PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 20 March 1970 [25 March 1969] 13484/70 Heading G4H If in a Michelson type interferometer the frequency or other parameter of the incident light is varied about an average value, the number of zero crossings of the intensity during a fixed time period is proportional to the displacement of one mirror with the respect to the other, and to the modulating frequency. Thus by counting the number of zero crossings the distance between the two mirrors may be measured. Light incident from a source 1 on a Michelson type interferometer passes via beam splitter 3, through quarter-wave plates 21 and 28. In this way the light passing through 28 comprises two beams of circularly polarized light which combine to form a single beam of linearly polarized light whose plane polarization is rotated with respect to that of the incident light, the angle of rotation being proportional to the displacement of the mirror 7. The light may be monitored by means of polarizer 23 and photodetechtor 25 whose output feeds into counter 26, and polarizer 24 whose angle is at 90 degrees to that of 23, and photo-electric detector 27 which also feeds into counter 26. The light incident at 1 may comprise two linearly polarized beams with planes of polarization at 90 degrees. The frequency of the incident light may be varied, or the frequencies of the two incident beams may be different, and the difference frequency may be varied.

Abstract: 497,323. Mercury switches. CIANCHI, A. May 13, 1937, No. 13579. [Class 38 (v)] In electric switch apparatus wherein conducting liquid is required to pass through a hole in a wall or partition, the thickness of material is reduced round the edge of the hole to obtain the desired rate of flow. Fig. 1 shows a hole 3 produced by drilling a conical depression 1 in a wall 2. Fig. 6 shows how the difficulty of making a small hole in glass or a ceramic material is overcome by covering a large hole 4 in a wall 2, with a sheet of metal 5 having a small hole 3 made as described. Other methods of making a hole are described including removing material from both sides of the wall, and filing a flat on a cylinder wall until a hole is produced or the thin material may be punctured by a needle. Fig. 7 shows a switch wherein a plunger 10 having an armature 2 with a hole 3 made according to the invention, floats in mercury in a container 1 encircled by a solenoid 9. Energization of the solenoid 9 pulls down the plunger 10 and displaces mercury which flows through the hole 3 until it reaches an electrode 15 to electrically connect it with an electrode 6. A valve at the bottom of the plunger allows a quick break when the plunger returns. Figs 2 and 5 of Specification 453,229 are referred to.
