Title: Improvements in the removal of carbon monoxide from gaseous mixtures by means of ammoniacal cuprous solutions
IPC: C01B3/02
Filed: 1924-08-16
Abstract: 220,651. Synthetic Ammonia & Nitrates, Ltd., (Assignees of Dely, J. G.). Aug. 16, 1923, [Convention date]. Hydrogen; nitrogen.-In the preparation of a mixture of nitrogen and hydrogen intended for the synthesis of ammonia from a mixture containing nitrogen, hydrogen, and carbon monoxide in which the latter is catalytically converted to carbon dioxide and hydrogen by means of steam, and the residual carbon monoxide is removed by absorption in ammoniacal copper solution the latter is recovered continuously together with the carbon monoxide which is then returned to the catalytic chamber. In Fig. 1 the gas to be purified enters the packed tower 1 under pressure through a pipe a and meets a downward stream of ammoniacal copper solution preferably at 0‹ C. circulated by a pump 2. The saturated liquor after passing through a reducing valve passes through a vessel 3 and tower 4 to a heat interchanger 5 and thence to a steam preheater 6 and regenerating tank 7 heated to about 70-75‹ C. by a coil 9. The regenerated liquor flows through the heat interchanger 5 to a brine cooler 10. Air is injected by means of an air lift into the liquor circulating through the tank 7 and pipe h, the latter having an enlargement 12 containing packing to ensure intimate contact between the liquid and the gas. The gas released in the vessel 3 owing to the fall in the pressure comprises principally carbon monoxide, hydrogen, and nitrogen and is conveyed through a pipe f to a water scrubber 8 and thence to the catalytic chamber. The gases evolved from the receptacles 5, 6, 7 containing large quantities of ammonia are passed into contact with cool unregenerated liquor in the tower 4 in which substantially all the ammonia is retained. Any oxygen in the gases entering at a is absorbed by the ammoniacal copper solution in the tower 1. In a modification of the process a single tower may be employed for the regeneration of the ammoniacal copper solution, which may be conducted under reduced or increased pressure.

Abstract: 750,428. Detecting gamma rays. TEXACO DEVELOPMENT CORPORATION. July 16, 1953 [July 26, 1952], No. 19754/53. Class 40 (3). [Also in Group XL (a)] Gamma rays are detected by converting them into light using the light to cause the emission of electrons, accelerating the electrons, and reconverting to light which is detected photoelectrically. As shown, the radiation to be detected is received on a luminescent screen, which may be as described in U.S.A. Specification 2,559,219. The scintillations of the screen are received on a photo-sensitive cathode 171 in a tube 12<SP>1</SP> the electrons emitted being received on a fluorescent target 20<SP>1</SP>. A velocity filter 30 for rejecting low velocity-thermal electrons is incorporated. Such a filter is described in U.S.A. Specification 2,548,118. A source of high potential 31 accelerates the electrons which are received on the fluorescent target 20<SP>1</SP>. The target has a coating of evaporated aluminium to prevent the re-emission of light into the tube. A coil 24<SP>1</SP> is provided so as to cause the electrons to flow radially from the cathode to the screen. The light emitted from the fluorescent screen is received on a photo-multiplier tube 10. The frusto-conical shape of the tube 12<SP>1</SP> has the effect of directing light from a large luminescent screen on to the cathode of a relative small multiplier tube. The arrangement of Fig. 1 (not shown) uses a cylindrical tube with cathode and fluorescent screens at opposite ends. In the arrangement of Fig. 3, the invention is embodied in apparatus for detecting radio-activity in boreholes. As shown, the luminescent substance is a liquid 11<SP>11</SP> and the light amplifying tube is of toroidal shape with the photo-cathode 17<SP>11</SP> on the inside of the outer curved wall and the fluorescent screen 18<SP>11</SP> on the inside of the inner. The detector is a photo-sensitive Geiger tube 10<SP>1</SP> and is situated in the centre of the toroid.

Abstract: 786,803. Electrolytic capacitors. WARREN, S. D., and BURKARD, R. F. July 8, 1955, No. 19903/55. Class 37. The electrolyte in an electrolytic capacitor comprises a substantially anhydrous mixture of an insulating organic solvent, preferably a ketone, a weak organic acid such as a phenol or cresol and an alkali metal base such as sodium hydroxide. The percentage of acid to solvent lies in the range 5-80 per cent and the percentage of base to acid lies in the range 0.03- 0.8 per cent. It is stated that under these conditions the capacitor can be made to operate satisfactorily when an alternating voltage applied thereto is biased by a direct voltage of less than the peak alternating voltage. The bias voltage may consequently be derived from a rectifier connected to the A.C. source as shown in Fig. 1 where the capacitor containing the anhydrous electrolyte is connected across the A.C. source 10 and is biased by a direct voltage derived by means of the rectifier 18. As shown in Fig. 3, the capacitor is housed within a metal can 25 to which the bias voltage is applied over the conductor 27 from the rectifier 26 connected to the terminal 28 of the capacitor.
