Patent GB-892069-A (GB)
Title: Improvements in or relating to the production of hydrogen
Inventor: COST JOE LEWIS
IPC: C01B3/50
Filed: 1958-11-05
Abstract: Residual methane is removed from hydrogen, which has been freed from other hydrocarbons and a portion of the methane by liquefaction, by scrubbing with hydrocarbon liquid from the liquefaction step after removal of substantially all its methane content by stripping with a portion of the purified hydrogen product.  The effluent scrubbing liquid may be stripped of methane and recycled.  The hydrogen may be freed from nitrogen, carbon monoxide and dioxide, and acetylene before the liquefaction step. The scrubbing liquid may comprise one or more of ethane, propane, propylene, isobutane, n-butane, n-pentene, and isopentane.  The scrubbing step may be effected at a temperature of -290 DEG F., a pressure of 30 p.s.i., and a mol ratio of gas to liquid of 21,7. The stripping step may be effected at a pressure of 30 p.s.i. and a mol ratio of gas to liquid of 1,67, the temperature of the stripping hydrogen being -40 DEG F. and that of the hydrocarbon liquid being -240 DEG F.  Liquefaction may be effected by passing the hydrogen under pressure through four multi-pass heat exchangers in series with a phase separator after each exchanger.  Liquid from the first separator may be entirely recovered as such.  Liquid from the second separator may be entirely passed back through the second and first exchangers and recovered as gas.  Liquid from the third step may be entirely passed back through the third, second and first exchangers, or passed successively through the scrubber and stripper and then back through the third, second and first exchangers, or passed partly back through the exchangers and partly to the scrubber as make-up for liquid recycled from the stripper.  Liquid from the fourth stage may be entirely passed back through the fourth, third, second and first exchangers, or passed partly back through the exchangers and partly to the scrubber as make-up for liquid recycled from the stripper.  If insufficient hydrocarbon liquid is produced in the liquefaction step, liquid hydrocarbon may be added from an outside source to that passed to the stripper.  The purified hydrogen and impure hydrogen from the scrubber may also pass through the fourth, third, second and first exchangers.

Title: Improvements relating to electrical coupling circuits
Inventor: CLARK RONALD ISAAC HERBERT
IPC: H04M11/10
Filed: 1953-12-24
Abstract: 757,624. Automatic exchange systems. SIEMENS BROS. & CO., Ltd. Dec. 3, 1954 [Dec. 24, 1953], No. 35860/53. Class 40 (4). In a circuit arrangement for coupling a telephone line to a piece of apparatus, such as a recorder, access is had from a final selector or from a group selector to a control circuit, the outgoing side of which is connected to the apparatus, the application of the exchange battery to the incoming wires of the control circuit causing an indication that the apparatus has been taken into use to be given; and on the release of the apparatus the reversal of the battery connections to the control circuit causes the giving of an indication that the use of the apparatus has ended. Access from final selector, Fig. 1. The wires from the final selector bank F/S are also connected to the line wires of a line circuit LC associated with the control circuit, a cross-over being inserted as shown. In response to dialled digits from a caller (not shown) the final selector seizes the control circuit shown and applies ringing current thereto. Relay R pulls up and bridges the incoming wires to operate the ring-trip relay in the final selector. Coupling relay D operates to the battery feed then extended by the final selector, disconnects R and its own winding (I) from the line and connects up its winding (II) and uncoupling relay CS which also operates. The line is thus extended to wires 1 and 2 leading to the recording apparatus (not shown) and lamp ENG lights in a local circuit over wires 5 and 8. When the caller clears, the guarding earth is removed from the test wire in the final selector and the line relay in the associated line circuit LC is connected up in known manner to the wires incoming to the control circuit. With the battery reversed, CS releases and immediately re-operates, but D, which obtains its armature during the reversal, is released. Lamp ENG is extinguished and a circuit is completed for lamp CL and buzzer BZ over wires 5 and 8. Relay CS may then be released by an attendant by operation of key RL. If automatic restoration of CS were desired, contacts cs1 cs2 would not be wired up. The recorder may be taken out of use by throwing key BK which connects up a permanent loop. Access from group selector, Figs. 2, 3. The group selector bank contacts are wired to a relay set (Fig. 2) including a feed bridge which in the idle condition applies resistance battery to the p-wire. Relay A pulls up to the seizing loop and B follows, thus changing over the battery connections to the control circuit (Fig. 3). Relay D operates and removes the short-circuit from the left-hand winding of CS which then operates in series with D; lamp ENG is lit. When the caller clears, A falls away and is followed by B and D; CS being held over its right-hand winding. To obtain automatic release of CS, the strap shown in the circuit of contacts cs1 would be omitted. An attendant may speak to users of either embodiment by operating the speak key SP to connect up her telephone set over wires T1.

Title: Improvements in or relating to the control of signalling apparatus by wireless
IPC: G08B1/08
Filed: 1929-11-25
Abstract: 343,924. Wireless control of distant signalling apparatus. PINTSCH AKT.- GES., J., 7], Andreasstrasse, Berlin. Nov. 25, 1929, No. 36040. Convention date, Dec. 12, 1928. Drawings to Specification. [Class 40 (v).] The apparatus at an unmanned signalling point or station used for aerial or marine navigation is brought into operation at exceptional times, i.e. when sudden changes in weather occur, by means of a wireless valve receiver associated with the signal equipment and controlled by wireless signals transmitted from a distant point of supervision. Once the signal plant has been brought into operation, it remains active until the receipt of a second wireless control signal. To avoid unnecessary expenditure of energizing-current, a clockwork switch open-circuits the valve filaments during those times when the signal equipment is normally in operation, e.g. at night in the case of a light signal. During periods when the main signal may be required to be set into action, the time switch energizes the valve circuits for a few minutes at half-hour intervals. Wireless signals received from the distant control point then operate a local relay to bring the main signal into or out of operation as required.
