Title: Process for controlling the reaction of metals with liquids
Inventor: ROSS FRANCIS J
IPC: C22B26/00
Filed: 1968-01-12
Abstract: 1,205,676. Controlled reaction of metal with liquid. E.I. DU PONT DE NEMOURS & CO. 12 Jan., 1968 [23 Jan., 1967], No. 1973/68. Heading C1A. Sodium, potassium or lithium, or alloys thereof, or calcium are reacted with an aqueous liquid whose specific gravity is greater than that of the metal under a layer of liquid which is immiscible and does not react with the aqueous liquid and whose specific gravity is less than that of the metal and aqueous liquid. The metal is immersed in the reaction medium and the reaction between metal and liquid takes place at the interface between the two liquids. The inert liquid is preferably a hydrocarbon oil, and the aqueous liquid may be water, or an aqueous chloride, hydroxide or cyanide solution. The reaction is carried out at a temperature at which both layers remain liquid, preferably in the range 0 to 100 C. When the metal reacts with the aqueous liquid, hydrogen is formed which adheres to the surface of the metal and lifts the metal from the liquid interface, causing the reaction to cease. As the hydrogen disengages, the metal sinks back to the interface. In order to prevent explosive mixtures of hydrogen and oxygen forming above the surface of the inert liquid, the surface may be swept with air, or an atmosphere of an inert gas may be maintained above the surface. Examples describe the application of the process to the disposal of sodium from sodium-filled plastic tubes of the type used for electrical conduction, and the disposal of sodium sludge filter resulting from the manufacture of sodium by electrolysis of molten sodium chloride.

Abstract: 558,486. Directive wireless signalling. COSSOR, Ltd., A. C., GODECK, J. E., and JOFEH, L. Feb. 21, 1941, No. 2395. [Class 40 (v)] A directional receiver, e.g. for direction-finding, &c., comprises two aerial systems the outputs from which are separately rectified and then combined in opposition, one of the groups having at least one minimum cusp in its polar response diagram, and the other having a substantially uniform response over the directions represented by at least one of the cusps. In one arrangement, three horizontal half-wave dipoles 1, 2, 3, Fig. 1, collinearly disposed are rotatable about a vertical axis 4, the centres of the dipoles 1, 3 being slightly less than one wave-length apart. The dipole 2 is connected to rectifier 10, and the dipoles 1, 3 to rectifier 8, the outputs of the rectifiers being combined in opposition in the circuit of the meter 11. In the polar response diagram, Fig. 5, A represents the response of dipole 2, B of dipoles 1, 3 jointly, and C the difference between A and B assuming that A and B have been adjusted so that the difference between them falls to zero for certain directions but is never negative. In a modified arrangement, the dipoles 1, 3 are disposed with equal and opposite inclination to the line joining their centres, Figs. 2, 6 (not shown). The meter 11 may be replaced by a cathode ray tube, in which the brightness of the spot increases from zero when the output of one rectifier exceeds that of the other. The dipoles may be associated with reflectors and directors to sharpen the maxima, Fig. 3 (not shown). In a further arrangement, four vertical aerials 20 ... 23, Fig. 4, are connected to a goniometer 25, the output from which is combined at rectifier 26 with the output from a non-directional aerial 24 to give a cardioid response, a second rectifier 28 receiving its input from the non-directional aerial alone, the outputs of the two rectifiers being combined in opposition. The curves 30, 31, Fig. 7, indicate the response of the two aerial systems, their difference influencing the indicator 29, being of low value except for the direction represented by the cusp of the cardioid 31.

The illustrated device, for recording morse code comprises keys 10 and 12 representing a dot and dash, which actuate electronic timer units T1-T4. The units actuate a tape drive 24 and pen relay 20 and prevent a further code element being printed until the tape has been advanced and an actuated key released. The pen relay causes a solenoid actuated pinch roller 72 to press the tape against a pen 64 for a timed period controlled by units T1, T3. After de-energization of the pen relay, the tape drive operates for another unit of time thus to give a spacing between symbols. The device may be conditioned so that a code symbol is printed in each of a plurality of equal lengths of the tape. A tape so printed can be read by a logical decoding system Fig.2 (not shown) for print out on a typewriter. Alternatively the symbols may be read directly from a tape or may be sensed by a photocell and transformed into a sound or pulse output Fig.3 (not shown).

Title: Improvements in and relating to steam plant for use with exhaust steam
IPC: F01K7/34
Filed: 1929-01-25
Abstract: 304,785. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Jan. 26, 1928, [Convention date]. Regulating.-In a back-pressure steam power plant in which a safety valve in the back-pressure pipe is arranged to open when the pressure becomes excessive, the safety valve is actuated by steam taken from a point in the exhaust pipe where the pressure is independent of the quantity of steam blown off. In Fig. 1, a high pressure main n fed by a boiler a supplies a turbine b which exhausts into a back-pressure main d. A safety valve g on this main is operated by a servo-motor c, f which is actuated by steam drawn off at a point m. In the arrangement shown in Fig. 2, the safety valve g, in addition to being controlled as described above is also influenced by the pressure in the main n so that, if an excessive pressure is reached in this main, the pressure at which the safety valve opens is lowered. A bye-pass between the mains n, d, is controlled by a steam pressure regulator h which is arranged so that it remains closed when the safety valve g is open.
