Abstract: 687,194. Cathode-ray tubes. PHILIPS ELECTRICAL, Ltd. March 3, 1948 [March 6, 1947], No. 6697/48. Class 39(i) A circuit for generating high frequency oscillators of the kind embodying a discharge tube wherein a beam of electrons emitted by a cathode passes through an aperture in a plane anode inclined to the beam at an angle in the neighbourhood of 45 degrees and strikes a secondary emission electrode parallel to the anode, has the voltages on and distance between the anode and secondaryemission electrode such that, in the absence of oscillatory voltage, the primary electrons just impinge on the secondary-emission electrode and the time of transit between the secondary-emission electrode and the anode is in the neighbourhood of one whole period of the oscillations to be generated. In the construction shown in Fig. 1 the beam from the hollow cathode 6 passes through the focusing electrodes 7, 8 and an aperture 3 in the copper disc anode 2 to strike the part 5 of the secondary-emission electrode 4, the part 5 being at a distance of 1.5 mms. from the anode 2. A glass wall 10 is sealed on top of the secondaryemission electrode 4 to take a cooling liquid. In the construction shown in Fig. 2 two cathodes 13, 14 and two pairs of focusing means 15, 17, 16, 18 formed as bodies of revolution are provided. Two strips 20, 21 which function as a Lecher line terminate in parts which are parallel to the apertured anode 12 and are coated with caesium oxide to form secondary-emission electrodes. With a voltage on the anode of 1400 volts and on the secondary-emission electrodes of 700 volts, oscillations may be produced in a wave length range of from 3 to 5 cms., the efficiency being approximately 20 per cent at a wave length of 5 cms. The mean voltage on the secondary-emission electrode or electrodes is chosen such that, for the anode voltage obtaining, the secondary emission coefficient has approximately its maximum value. The ratio between the voltage on the secondaryemission electrode and that on the anode is preferably chosen to be substantially equal to the square of the sine of the angle which the electron beam makes with the anode plane.

Title: Method of producing coatings of high melting nitrides on metals
IPC: C23C16/02
Filed: 1953-03-16
Abstract: Coatings of high-melting point nitrides of elements E are formed on metals or alloys M which have a reducing action on the halide of the element E and of which the halides are readily volatile below the melting-point of the metal M, by pre-casting from a nitrogen atmosphere containing at least one halide of the element E at a temperature at which the reaction is not intensely retrogressive, followed by deposition on the pre-coated metal surface at above 400 DEG  C. from a nitrogen-hydrogen, ammonia, ammonia-hydrogen, ammonia-nitrogen or ammonia-hydrogen-nitrogen atmosphere containing at least one halide of E.  Titanium nitride coatings may be formed on iron using titanium tetrachloride. Coatings of nitrides of one or more of Zr, Hf, V, Nb, Ta and B may also be formed and by including hydrocarbons in the gas mixtures, mixtures of nitrides and carbides may be produced.  To avoid deposition on the object of nitrides formed in the gas space of the reaction chamber, the object to be coated may be heated directly by resistance or induction heating, and/or may be continuously turned; preferably, however, the object is enclosed in a shell closely conforming to the shaft of the object, to provide as little gas space as practicable around it; such shell may itself be of iron coated with titanium nitride.

Title: Process for the manufacture of sodium carbonate and chlorine
IPC: C01D7/07
Filed: 1967-02-15
Abstract: Sodium chloride containing caustic liquor, produced together with hydrogen and chlorine by electrolysis of aqueous sodium chloride in diaphragm cells, is divided into two parts, one of which is used to recover ammonia from the filtration stage of an ammonia-soda process undergone by the other part, the solution of sodium chloride leaving the ammonia-recovery stage being resaturated with sodium chloride, purified and returned to the electrolytic cells.ALSO:Sodium carbonate and chlorine are produced in a cyclic process combining the ammonia-soda process, the carbonation of sodium chloride-containing caustic liquor, and the electrolysis of aqueous sodium chloride solution in diaphragm cells, characterized in that the sodium chloride containing caustic liquor, produced by electrolysis of sodium chloride, after leaving the electrolytic cells is divided into two parts, of which one is precarbonated by means of a gas containing carbon dioxide before being introduced into the ammonia-soda process at the ammonia-absorption stage; the other part being used to recover ammonia from the mother liquor from the filtration stage of the ammonia-soda process, the solution of sodium chloride leaving the ammonia-recovery stage being subsequently resaturated with sodium chloride, purified and returned to the electrolytic cells. The precarbonating gas may have a CO2 content, of less than 20% by volume, and be used in sufficient amount to convert all the caustic soda present to sodium carbonate.  To avoid precipitation in the ammonia absorbers, a part of the mother liquor from the filtration stage may be recycled to ammonia-absorption stage, in the proportion of 15% to 20% of the total weight of the mother liquor.

Abstract: 634,319. Vehicle wheels. DEMETRIADES, G. A. March 17, 1947, No. 7319. Addition to 615,182. [Class 144 (i)] [Also in Group XXIV] In a wheel or like rotary body, the hub 10 is mounted on bearings 12 on a stub shaft 14 and is provided with two screw threads 26, 30 of opposite hand on to which are screwed a member 24 carrying a rim 22 and a hub cap 34 carrying a flange 36. The hub 10 has a flange 16 to which a brake drum 18 is attached by means of screws 20. The rotation of member 24 relative to the hub 10 in one direction is prevented by engagement of complementarily tapered surfaces 28 on the brake drum 18 and member 24. Relative rotation in the opposite direction effects closer engagement of complementary surfaces 38 on members 36, 24 and a tendency for member 34 to screw further on to shaft 10 by virtue of the screwthreads 26, 30 being of opposite hand. In a double wheel assembly, Fig. 2, rims 22 are carried by members 24, 25 screwed on to hub 10 and having complementary surfaces 40. A member 11 bolted to hub 10 has a screw-thread 30 of opposite hand to thread 26 on to which is screwed a member 34 carrying a flange 36 engaging a surface 38 on member 25. Brake drum 18 and end cap 34 limit axial movement of the wheels as in the previous embodiment.
