Title: Improvements in or relating to method for separating carbon dioxide and hydrogen sulfide from gas mixtures
IPC: C10K1/12
Filed: 1955-03-01
Abstract: <PICT:0790287/III/1> The process of the parent Specification of absorbing carbon dioxide or hydrogen sulphide from gases by alkaline solutions, particularly potassium carbonate, under superatmospheric pressure, regenerating by boiling and steam stripping at about atmospheric pressure and returning the solution to the absorber at about atmospheric boiling temperature, is modified by conducting the regeneration under sub-atmospheric pressure corresponding to a boiling temperature of 170 DEG  F. and upwards.  The apparatus may be the same as that of the parent Specification with the inclusion of a vacuum pump &c. to maintain sub-atmospheric pressure in the regenerator column; a separate flashing vessel immediately after the absorber may be dispensed with.  Part, e.g. 2/3 , of the regenerated solution may be introduced at an intermediate level of the absorber, the remainder being cooled e.g. 30-100 DEG  F. and introduced at the top.  Or this minor stream, with or without subsequent cooling, may be subjected to more thorough regeneration.  Fouled solution from an absorber 202 maintained e.g. at 300 lb. per sq. in. pressure passes through a letdown valve 208 to a regenerator 209 in which a sub-atmospheric pressure, e.g. corresponding to a boiling temperature of 200 DEG  F. at the bottom of the column, is maintained by a vacuum pump 215 which draws off carbon dioxide &c. from a separator 212 collecting effluent from the top of column after passage through a condenser 211.  Most of the regenerated solution is recycled through a line 204 to an intermediate level of the absorber.  A minor quantity is pumped to a secondary regenerator 223 maintained e.g. at about 30 lb. per sq. in. pressure (boiling temperature 290 DEG  F.) stripping steam being provided by means of a closed coil receiving exhaust steam from the vacuum pump turbine 217 or by direct input of steam.  The regenerated solution passes through a let-down valve 229 to a flashing vessel 320 from which steam is supplied to the main regenerator and the cooled solution through a coole 234 if desired, to the top of the absorber.  Corrosion inhibiting material, e.g. 0.2-0.3 p.c. of sodium dichromate by weight of the potassium carbonate may be employed.  Sodium carbonate and potassium phosphate may be used as scrubbing solutions. Specifications 790,288 and 790,289 also are referred to.

Abstract: 489,516. Valve relay circuits. BRITISH THOMSON-HOUSTON CO., Ltd. March 1, 1937, No. 6072. Convention date, Feb. 27, 1936. [Class 40 (v)] [Also in Group XXXV] In the control of a reversible motor with separate fields on the anode circuits of valves 31, 32 the grids of these valves are energized by A.C. at a predetermined phase angle, but a variable D.C. component is supplied from a normally balanced resistance bridge 42, 43. The resistance 42 is in the output circuit of valves 36, 37 containing an ionizable medium and connected across a resistance 49 forming part of a potentiometer 49, 50 supplied with D.C. A second potentiometer across the same D.C. terminals comprises resistances 46, 47, 48, and the grids of triodes 36, 37 are connected through resistances 60, 61 respectively to a point 46a thereon. The output of amplifiers 55, 57 and 56, 58 passes through the resistances 60, 61 respectively. The second stage valves 57, 58 are grid biassed so as normally to supply current to the resistances 60, 61 and so hold the valves 36, 37 nonconducting. Each time a photo-cell 26, 28 is activated the resulting change in output of the associated amplifier reduces the grid voltage of the valve 57 or 58 so that the valves 36, 37 carry current. When these activations are not simultaneous one of the valves 36, 37 conducts first and unbalances the bridge 42, 43 so that the corresponding winding of the motor 24 is energized through the corresponding valve 31 or 32. Commutation of the valves 36, 37 is obtained by valves 62, 63, the first being rendered conducting by the charge built up in condenser 66 whereupon the transformer 69 causes the valve 63 to send current through resistance 50 sufficient to raise the cathode potentials of valves 36, 37 above that of their anodes ; at the same time anode 63b discharges condenser 66 to reset the system.

Abstract: 368,053. Tufting-machines. GROVES, W. W., 30, Southampton Buildings, London. -(Carter Bros., Inc. ; Cherokee Boulevard, Chattanooga, Tennessee, U.S.A.) Feb. 27, 1931, No. 6187. :Class 112.] A row of needles on a tufting machine form free loop stitches which are caught by bills and severed by a row of cutters, any of which can be removed, arranged below the throat plate. The threads are led through a thread tension device 159, Fig. 4, to the needles 18. The fabric is fed from the front of the machine between two discs 43, 49 and passes beneath the presser foot 46. When the machine is started the needles pass through the fabric and the bills 117 are rotated about pivots 110 by cam 124 on the main shaft 8, and grip the loops against the fixed plate 119, where they are cut by an upward movement of the cutters 149, Fig. 6. The loops are then seized between teeth on two relatively sliding plates 76, 81, carried by a rocking frame 73 and are moved rearwardly, Fig. 7, with the fabric to clear the needles on their next descent. The toothed plate 76 is moved over the toothed plate 81 to grip the severed loops by a cam 99 on the main shaft 8 and bent arm lever 102, 98, Fig. 9. The rocking movement of the frame 73 is given by a cam 101 on the shaft 8, Fig. 6. The cutters are reversible and any number can be removed to vary the design.

Title: Improvements in or relating to intercarrier television receivers
IPC: H04N5/50
Filed: 1954-03-03
Abstract: 753,682. Diplex radio signalling; radio receiving circuits. PARKER, L. W. March 3, 1954 [March 11, 1953], No. 6260/54. Class 40 (5). In an intercarrier television receiver, the video carrier is demodulated by means which also pass on the modulated carrier to an amplifier for the demodulated signals, which feeds said carrier to beat carrier producing means connected to the audio demodulator. In one embodiment, the I.F. carriers from transformer 10 are fed to a diode 11 shunted by a capacitor 20 which feed the demodulated video signal and the two carriers to an amplifying pentode 17. The video output of valve 17 is fed, through a filter 26 ... 30, to the picture tube 25, while the two carriers are fed through a capacitor 34 and transformer 33 to a diode 38 in which intermodulation occurs. The beat frequency carrying the audio modulation is selected by transformer 42 and demodulated by diode 47, and the audio signal is amplified by the variablegain triode 53. As the amplitude of the video carrier is arranged to be considerably greater than that of the audio carrier, the D.C. voltage developed across the circuit 40, 41 in series with diode 38 is mainly dependent upon the video carrier amplitude and is used to control the gain of audio amplifier 53, so that aural tuning may be used to ensure maximum video carrier amplitude. A limiter diode 63 may be provided to set an upper limit to the positive bias on valve 53. In a second embodiment, the video carrier is derived from valve 17 and the audio carrier from a coil coupled to transformer 10, for application to the diode 38, and a limiting diode is associated with the video carrier feed, Fig. 3 (not shown). In another example, the valve 17 not only amplifies the video carrier and the demodulated video signal but also the beat frequency carrier before its application to the audio demodulator or discriminator, Fig. 4 (not shown). Specification 655,153 is referred to.

Abstract: 1378681 Fuelling reactors UNITED KING- DOM ATOMIC ENERGY AUTHORITY 16 Jan 1973 [11 Feb 1972] 6521/72 Heading G6C A fuel element transportation canister comprises a cylinder 1 forming a primary chamber for containing fuel elements 23 submerged in water, and six tubes 3 disposed about the cylinder 1 forming a secondary chamber for containing water and pressurized air. The tubes 3 are interconnected at their lower ends by a manifold 4 and connected with the cylinder 1 by a coiled tube 5 which makes one full turn about the cylinder 1. Within the cylinder 1 there is a removable magazine 6 comprising six open-ended tubes 7 which house the fuel elements 23. The magazine 6 is loaded with irradiated fuel elements under water. To load the magazine into the canister, the canister is lowered into the water with its cover removed so that the cylinder 1 fills up and the tubes 3 are partially filled from the lower end by way of the coiled tube 5, the air trapped within the tubes 3 being compressed by hydraulic pressure. The loaded magazine 6 is then placed in the cylinder 1, the cover of which is secured by bolting. The coiled tube 5 serves as an air lock to prevent the trapped air passing from the tubes 3 to the cylinder 1 during handling and conveyance but enables water to flow between the cylinder 1 and the tubes 3 due to volume changes caused by temperature variations. The use of tubes for the secondary chamber instead of an annular jacket enables more efficient cooling of the cylinder during conveyance in a transportation flask.
