Filed: 1916-01-25
Abstract: 100,066. Aktiebolaget Ingeniorsfirma F. Egnell. Feb. 6, 1915, [Convention date]. Gas analysis. - In automatic gas analysis apparatus, liquid is caused to rise and fall in a pipe system so as to draw gas into a measuring-vessel b, Fig. 1, from a pipe e, and to expel the measured volume through a seal g and heated receptacle h containing an oxidizable metal or an oxide or both into the measuring-bell l, from which it is expelled through a pipe i which branches, one branch leading direct to the bell l, and the other to the receptacle h and thence to a vessel o having a pipe p. The motion of the bell depends on the quantity of gas absorbed in h. Potash absorption-vessels may be inserted, in this modification. In one form, Fig. 2, potash is placed in the vessel o, which is provided with an inner vessel s containing the pipe p, the vessels s, o being connected by a pipe t leading to and from the receptacle h. The vessel s may contain water, glycerine, or the like. The oven h may contain iron or an oxide of iron or copper, or a solid mass formed by sintering a pulverulent metal; and two ovens may be used, one for the metal and the other for the oxide. The oven or ovens mav be heated electrically. The Specification as open to inspection under Sect. 91 (3) (a) describes other modifications, in which the gas stream is not divided on leaving the measuring vessel b. Such an arrangement is shown in Fig. 1 (cancelled), all the gas leaving the oven h being passed to the bell l. Various arrangements are described for the estimation of the total proportion of particular groups of ingredients, the apparatus being varied by inserting a potash absorption vessel between band h; or in front of b and between h and l; or in the latter arrangement the positions of h and l map be transposed. It is also stated that in the modification shown in Fig. 2 the vessel S may contain potash, in which case it can have an open bottom. This subject-matter does not appear in the Specification as accepted.

Patent GB-774563-A (GB)
Title: Process for the production of hydroxyalkane-sulphonic acids from their salts
Filed: 1955-01-17
Abstract: Hydroxy alkane alkane sulphonic acids are prepared by contacting aqueous solutions of their water-soluble salts with a cation-exchanger containing sulphonic acid groups such as acid Wofatits.  The water-soluble salts may be alkali metal, ammonium, organic base, calcium, magnesium or aluminium salts.  The resulting free acids, wherein a chain of at least 3 carbon atoms separates the hydroxyl and sulphonic acid groups may be converted into the corresponding sultones by splitting-off water by heating. The acid salts may be prepared by reacting allyl or other unsaturated alcohol with a bisulphite.  In examples: (1) an aqueous solution of sodium hydroxy propane sulphonate is passed through a column of Lewatit S 100 and the effluent is evaporated in vacuo to remove water; the resulting 3-hydroxy propane-1-sulphonic acid is heated at 130 DEG  C. under water-pump vacuum to give the sultone; (2) aqueous sodium 4-hydroxy butane-1-sulphonate is treated as in (1) to yield the free acid and then the corresponding sultone; (3) aqueous sodium hydroxypropane sulphonate is prepared by addition of sodium bisulphite to allyl alcohol in the presence of finely divided air and then diluted and treated as in (1).  German Specification 887,341 is referred to.

Title: Improvements in coaxial transmission lines, particularly in the termination thereof
IPC: H01P1/26
Filed: 1944-02-01
Abstract: 575,511. Current and voltage measuring apparatus ; non-metal resistances. MARCONI INSTRUMENTS, Ltd., and HUNT, E. W. Feb. 1, 1944, No. 1869. [Class 37] A resistive termination for a coaxial transmission line includes a centrally apertured carbon disc, of which the outer periphery makes contact with an extension of the outer conductor of the transmission line and the periphery of the central aperture makes contact with an extension of the inner conductor. An outer conductive tubular member 7 is internally threaded at both ends and provided with an abutment 8. Into one end is screwed a tubular member 3 having an internal diameter equal to the internal diameter of the transmission line. Coaxially supported by insulating material 9 is an inner conductor 4 having an external diameter equal to that of the inner conductor of the transmission line. The terminating resistor comprises a carbon disc 1 with a central aperture, the outer and inner cylindrical surfaces c, d and adjacent rings a, b on both flat faces being metallised. The disc is threaded on the conductor 4 so that the metallised surface d makes contact therewith. The member 3, conductor 4 and disc 1 are then screwed into the member 7 so that connection is made between the metallised surfaces a, c continuously around the disc, with the members 3, 7. A crystal rectifier 2 is connected to the conductor 4 by a plug and socket 10. Screwed into the right-hand end of the member 7 is a conductive plug 11 having a coaxial bore through which passes an insulated shank 12 having an inner terminal 6 for connection to the other end of the crystal rectifier 2. The outer face of the terminal 6 and the inner end of the plug 11 are insulated from each other by a disc 5 of mica and form a by-pass condenser for high-frequency energy. Between the shank 12 and the outer member 7 is connected a micro-ammeter which measures the voltage drop across the resistor 1. The resistor 1 may be made by drilling through the centre of a carbon resistor of 2-watt rating (e.g., Erie R.M.A.1.) nominal value 400-1,000 ohms and parting off a section # in. wide. The entire surface is then electroplated with copper and a ring of the deposited copper is removed from each end surface until the resistance from the centre to the outer edge is of the required value. The completed section is then impregnated with wax. Specification 556,726 is referred to.
