Title: Improvements in or relating to systems for controlling a process for generating a vapour
Inventor: ROGERS MARK ANTHONY MEYRICK
IPC: F22B35/00
Filed: 1963-02-11
Abstract: 1,001,669. Controlling steam generators. INTERNATIONAL SYSTEMS CONTROL Ltd. Jan. 30, 1964 [Feb. 11, 1963], No. 5478/63. Drawings to Specification. Headings F4A and F4B. In a control system for a vapour generator, the most efficient operation possible is obtained by feeding signals representing the steam output rate, temperature and pressure, the feed water input temperature, the fuel supply temperature and pressure, the temperature and pressure of the primary and secondary air supplies, the flue gas temperature and oxygen content and the rate of flow and temperature of the recirculated flue gases to a stored memory computer programmed to derive an expression indicative of the useful heat output/heat input ratio at short intervals, average this value after a number of intervals, and produce signals representing the necessary adjustments to the primary and secondary air supply controls, induced draught control and flue gas recirculation controls to maintain the optimum heat output/heat input ratio. These signals are utilized to provide visual instructions to an operator, or may operate the controls automatically. The water level in a steam-water drum is maintained constant independently, but the computer may be programmed to determine the number of burners to be used for a given steam output rate and temperature, and to maintain such factors as the flue gas oxygen content and power consumption of the various fans within acceptable limits.

Patent GB-634391-A (GB)
Title: Improved process and catalyst for the dehydrogenation of olefines
IPC: C07C5/32
Filed: 1947-02-28
Abstract: A dehydrogenation catalyst comprises calcium nickel phosphate and is prepared by adding an aqueous solution, e.g. water or other ionizing solvent comprising water such as aqueous alcohol, dioxane, glycerol, or ethylene glycol, of calcium and nickel salts, such as chlorides, nitrates, or acetates in the proportion of 7.5 to 9.2 atoms of calcium per atom of nickel, to a solution of a soluble phosphate, preferably in slight excess, e.g. di- or tri-sodium phosphate, di-potassium phosphate or di-ammonium phosphate, and maintaining the mixture in a neutral or alkaline condition, e.g. pH 8-12. Alternatively, an aqueous solution of ortho-phosphoric acid, and calcium and nickel salts may be added to aqueous alkali.  Preferably the alkaline mixture contains an ionizable basic nitrogen compound, e.g. ammonia, water-soluble ammonium salt, or water-soluble amine or amine salt such as di- or tri-ethylamine or diethanolamine.  The gel-like precipitate of calcium nickel phosphate is separated, washed, dried at 60-150 DEG  C., and crushed; it may be used thus or made into granules with a lubricant, e.g. graphite, vegetable oil or hydrocarbon oil, which may be removed by oxidation or vaporization by passing air or air and steam through the catalyst at 450-750 DEG  C., preceded if necessary by a stream of inert gas.  The catalyst may be reactivated at intervals by passing air and steam through at 450-750 DEG  C. and may be remade after extensive use or to improve activity by dissolving in aqueous mineral acid, e.g. hydrochloric or nitric acid, filtering, and adding the solution to aqueous alkali to precipitate the gel, which is treated as before. U.S.A. Specification 2,178,601 is referred to.ALSO:Olefines having at least 4 carbon atoms in the chain containing the olefinic linkage are thermally dehydrogenated by passage with steam, which may be superheated, through a granular bed of p  catalyst which consists essentially of phosphate radicals chemically combined with calcium and nickel in the relative proportions of between 7.5 and 9.2 atoms of calcium per atom of nickel (see Group III), at a temperature 550-750 DEG  C. with or without pressure.  The mixture of steam and olefine may be 10-20 volumes of steam per volume of olefine and the product gases are cooled and separated by known means, e.g. fractional distillation. The bed of catalyst may be swept with steam at 450-750 DEG  C. before use while the catalyst may be reactivated at intervals by passing air and steam therethrough at 450-700 DEG  C. or may be remade after extensive use or to improve activity by dissolving in aqueous mineral acid, e.g. hydrochloric or nitric acid, filtering, and adding aqueous alkali to reprecipitate the catalyst.  More than one catalyst bed may be used, one being reactivated while the other is in use.  Examples describe the conversion of butylene to butadiene amylene to isoprene, treatment of C4 fraction of cracked oil gas, or cyclization of hexene to benzene.

Title: Improvements in or connected with remote-control coupling and uncoupling devices for toy electric railways
Inventor: ALTON WERNER
IPC: A63H19/18
Filed: 1951-03-12
Abstract: 678,257. Electromagnetic switches. TRIX, Ltd. March 12, 1951. No. 5877/51. Class 38 (v). [Also in Group XV] Electromagnetic switching of a remotely controlled coupling and uncoupling device for toy electric railways includes two solenoids mounted end to nd, and means for selectively energizing the solenoids. In Fig. 1, a locomotive has a switch magnet 4 which when energized by a current impulse from a controller, causes a switch drum 8 to be turned one step and current to be supplied to the driving motor. A further impulse causes a solenoid 25 in tender 18 to be energized via drum 8 and a contact plate 36 with which a contact post 33 mounted on a solenoid plunger 30 makes sliding contact (Fig. 8). The plunger 30 is thus drawn rearwardly causing contact between plate 36 and contact post 33 to be broken, and a contact post 32 to make contact with a plate 40. The hook portion 44 of coupling member 43 is thus depressed, uncoupling a carriage 60. The next control impulse causes current supply to the driving motor to be broken and solenoid 26 to be energized via the contact plate 40. Plunger 30 is thus drawn forward again to the position shown in Fig. 1 and the coupling member. returns to the coupled position.

Title: Improvements in or relating to protective or safety devices for electrically propelled vehicles
IPC: H02H3/14
Filed: 1933-02-28
Abstract: 415,713. Protective cut-out arrangements. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and CROFT, E. H., c/o General Electric Co., Witton, Birmingham. Feb. 28, 1933, No. 6126. [Class 38 (v).] A safety device for an electric vehicle comprises means for withdrawing the current collectors 2 from the conductors 1, and means adapted, upon the occurrence of a potential difference between the vehicle and earth, to effect the withdrawal of the collectors. The withdrawing means may be operated by the pressure or vacuum of the brake system and may comprise cylinders 3 to which pressure or vacuum is admitted by an electrically operated valve 14 when the potential difference occurs. At the same time the main switch 6 of the driving motor 4 may be opened by the deenergization of the coil 8. The controlling means may comprise a relay 12 connected on one side to the anode 16 of a thermionic valve 17 and on the other to the positive side of a battery 9 which is connected on the negative side to the coils 8, 13. Normally the relay 12 is energized and keeps contact 11 closed and 10 open, so that coil 8 is energized to close switch 6 while coil 13 is dead and valve 14 is closed. The cathode 18 is connected across part of the battery, and the grid 19 is connected to the vehicle body 21 through a resistance 20. A relay 22 which is cyclically energized and de-energized by means of three slow-releasing relays 39, 40, 41 forming a self-interrupting chain and connected across part of the battery, controls two sets of contacts 23-27 and 28-32. When the relay 22 is dead, contact 29 makes with 28, contact 31 with 32, and contact 24 with 25, so that condensers 35, 37 and their resistances 34, 36 are in parallel between the negative supply line through fuse 38 and trailer wheel 33, and are equally charged. When the relay 22 is energized, contacts 29, 24 make with 30 and 25 respectively, and condenser 37 is placed in series between the body 21 and the negative line, while condenser 35 is disconnected on one side. If a leak, shown by the broken line 43, occurs between the body 21 and the negative line, condenser 37 will be partly discharged. As the contacts 24, 29 continue to lift, 27 makes with 23, and 31 breaks with 32, so that condensers 37, 35 and resistances 36, 34 are in series between the grid 19 and the negative side of the cathode, in parallel with the resistance 20. The discharge of the condensers through 20 sets up a potential drop which biasses the grid 19 so that the anode current through the valve 17 drops sufficiently to release the contacts 10, 11, thereby opening switch 6 and the valve 14.

Abstract: 493,140. Electron - oscillators and circuits therefor. FARNSWORTH TELEVISION, Inc. March 2, 1937, No. 6184. Convention date, March 9, 1936. [Classes 39 (i) and 40 (v)] Oscillations are generated by projecting a stream of electrons from an external electron gun into the space between two opposed electrodes and applying an accelerating positive potential to an anode disposed between the electrodes so as to cause the electrons to oscillate between them without striking so as to give up energy to the electrodes electrostatically before being finally collected by the anode ; the energy so absorbed controls the number of electrons entering the space in such a way as to maintain oscillation. In the form shown, the heated filament 9 emits electrons which pass through a grid 10 and an aperture 6 in an electrode 5 towards a similar electrode 2, the electrodes 2, 5 being connected to a tuned circuit 14 and a transmission line or the like 16. The anode 11 is connected to a source 17 and an axial magnetic or electric field is provided for focusing the electron stream. The grid 10 may be provided with a modulating potential to modulate the output of the device or the device may serve as a Class C amplifier or a separately excited oscillator when a grid exciting voltage is applied through line 23 from a master oscillator, for example. The frequency of the input voltage must then be the same as that of the tuned circuit 14. The device may be provided with a second heated filament, symmetrically arranged behind the electrode 2, when the device is connected for push-pull amplification. Preferably, the field distribution increases parabolically as the electrode 2 or 5 is approached from the anode 11. Specification 488,661 is referred to.
