Title: Improvements in and relating to driving mechanism for paper making machines
IPC: D21F7/02
Filed: 1919-06-05
Abstract: 154,644. British Thomson-Houston Co., and Shuttleworth, N. June 5, 1919. Speed-maintaining systems.-In driving-mechanism for paper-making machines wherein separate electric motors drive different sections of the machine, alternating-current commutator motors are used for this purpose and the speeds of all the motors are kept proportional under varying loads by automatically operating brush-shifting gears. The motors 1, 6, &c. drive the sections through gear-boxes 3, 7 and shafts 2, or otherwise, and one motor drives a master shaft 4 through gearing 5. A sleeve 8 associated with each of the other motors is rotated on the shaft 4 through a variable-speed gearing, for example cone pulleys 6a, 8a, and is connected with one member of a differential gear inside the casing 9 thereof, the other member inside the casing being connected to the shaft 4. When any motor is rotating at the correct speed relatively to the shaft 4, the gear casing 9 is stationary, but variation of speed causes the casing to rotate, its motion being transmitted to the worm-gearing 15 of the brush-shifting gear. An electro-magnetic or other clutch 18 enables the brush-shifting gear to be disconnected when the corresponding motor 6 is not in use. According to a modification, the differential gear is arranged on a shaft parallel to and driven from the master shaft 4.

Abstract: 354,788. Capacitance measurements. STANDARD TELEPHONES & CABLES, Ltd. and NIELSEN, N. P., Columbia House, Aldwych, London. May 14, 1930, No. 14811. [Class 37.] A bridge for measuring capacity unbalance, for example in a telephone cable, is so arranged that substantially equal capacities may be added to each of two opposite arms and subtracted from each of the other two opposite arms. Fig. 2 shows a bridge in which the four arms A .. D are formed of four separate condensers mechanically connected, as by being mounted on the same spindle. The two pairs of one quad in the cable are connected to the points 1, 2 and the two pairs of the second quad to the points 3, 4. A modification is shown in Fig. 4 in which the bridge has two movable sets of plates 9, 10 and four fixed sets A .. D. The sets A, C and B, D may be combined as shown in Fig. 6. The bridges shown in Figs. 2, 4, and 6 may be connected as shown in Figs. 3, 5, and 7 for measuring phantom to side circuit unbalances. The bridge may be shielded. The direct capacities between the corners of the bridge may be rendered equal by known methods, and equality of the direct capacities of the corners to earth may be ensured. The arms may be adjusted to have equal initial capacities by the use of separate fixed or variable condensers, and similar condensers may be used for varying the range. Instead of mounting the movable plates on the same spindle, gearing may be employed so as to allow for initial adjustment of the capacities of each of the arms.

Abstract: A process of carrying out exothermic vapour phase reactions at high pressures in the presence of a stationary catalyst bed comprises passing a flow of incoming gases first through central core tubes of bayonet cooling elements in the catalyst bed, then in the opposite direction through annuli between the core tubes and concentric outer tubes of said cooling elements and in indirect heat exchanging relation with the catalyst, then through and in contact with the catalyst in the same direction as the gas flow through said annuli while preventing heat exchange between the gases in the core tubes and those in the annuli.  The following features are preferred:- (a) the incoming gases are a N2-H2 gas mixture, pres <PICT:0843882/III/1> <PICT:0843882/III/2> <PICT:0843882/III/3> sure above 100 atm; (b) thermal insulation is provided between the core and outer tubes, particularly comprising stagnant gas insulation in insulating tubes; (c) each core tube is attached at its end to the inner surface of a hollow block having a longitudinal flange to which the insulating tube is fastened and the blocks are carried by a tube sheet extending across the catalyst cartridge.  An apparatus for carrying out the above process is shown in the diagrams of which Fig. 1 shows a vertical section of an ammonia synthesis converter, Fig. 2 shows the structure of the said bayonet cooling elements and Fig. 3 is a horizontal section on the line X-X of Fig. 1; in all the Figures, the numerals 14 and 15 denote respectively the core tubes and the outer tubes of the cooling elements.  In the example, this converter was operated at 1000 atm. and space velocities of about 90,000 to produce 42-43 tons of ammonia per 24 hours using a synthesis gas containing about 68% by volume of a 1:3 N2-H2 mixture and 30-32% of inert gases (principally methane and argon) the catalyst being Fe3O4 promoted with small amounts of K2O and Al2O3 and reduced with H2 before use. The catalyst bed was 7.3 feet long and 17" diameter; the outer tubes 15 were 1" outside diameter and the catalyst volume therefore 7.4 cu. ft.  Inlet gas temperature at the core tubes 14 was 630 DEG F. and the catalyst temperature 860-935 DEG F.  The lower ends 17 of the core tubes were about 1 foot from the closed ends of the outer tubes 15.
