Title: Method of recovering sulphur dioxide
IPC: C01B17/60
Filed: 1939-01-16
Abstract: 523,845. Recovering sulphur dioxide. GUGGENHEIM, M., GUGGENHEIM, S. R., SMITH, E. A. C., and WHELPLEY, M. G. B. [trading as GUGGENHEIM BROS.] Jan. 16, 1939, No. 1467. Convention date, Jan. 17, 1938. Drawings to Specification. [Class 1 (ii)] In the recovery of sulphur dioxide from gases by contacting the gases with an absorption liquid containing dimethyl aniline, heating the absorption liquid to liberate the sulphur dioxide and collecting the liberated sulphur dioxide, a series of pools of the absorption liquid are formed by flowing the absorbent down through an apparatus of the bubble-plate tower type, the gases are passed upwardly through the pools of liquid at atmospheric pressure, and one or more of the pools of liquid are cooled to dissipate the heat developed during the absorption. The cooling may be such that the dimethyl aniline is kept at a temperature below 20‹C. preferably below 15‹C. The waste gases leaving the top of the tower may be washed by a reagent such as sulphuric acid to remove any entrained dimethyl aniline. The solution charged with sulphur dioxide from the bottom of the tower may be preheated by heat exchange with the stripped liquid and then fed to the top of a stripping tower which may be of the packed or bubble plate type. Heat is applied to the base of the stripping tower either by the direct introduction of steam, or by maintaining a body of water or a dilute solution of ammonium or alkali sulphite at the base of the tower and applying heat indirectly. In the latter case the water &c. carried out of the tower by the organic liquid may be separated in a settling tank &c. The sulphur dioxide leaving the top of the stripping tower may be passed first through a condenser and then into contact with sulphuric acid.

Abstract: 967,192. Fractional distillation under reduced pressure ; contacting gases with liquids. R. D. BEATTIE, and D. F. OTHMER. Jan. 16, 1961 [Jan. 18, 1960], No. 1776/61. Headings BIB and B1R. A vapour/liquid contact apparatus comprises a column divided internally into a number of contact stages 12 by horizontal plates 14 with a central opening 16, each stage containing a multi-bladed rotor 24 rotated with a shaft 18 and arranged to force vapour rising through a central opening 16 outwardly in contact with atomized liquid descending from the stage above. The rotor blades may have top and bottom cover plates and in the embodiment shown in Fig. 1 the liquid descending through a central opening is collected in a cage 26 above the top cover plate and distributed outwardly therefrom by centrifugal force. Vapour is supplied by a reboiler 28 to which liquid reflux is returned by a pipe 36, and vapour is condensed at 40, distillate being drawn off at 50 and reflux liquid returned to the column by a pipe 48. The apparatus may be operated under reduced pressure by connecting an ejector or vacuum pump to the reflux drum 46 through a pipe 49. In the embodiment shown in Fig. 4 liquid is delivered to a rotor 24 by pipes 68 and the liquid is dispersed at about the level of the cover plate. The inside of the column may have static vanes which may be straight vertical strips or helical strips, see Figs. 2, 3 respectively (not shown). Packing material may be placed in the free space of each stage and the lower portion of a rotor may seal in a pool of liquid on a plate 14. The plates 14 may have grooves delivering liquid to the outer portion of a plate 14 instead of, or in addition to, the opening 16. Three specific examples are described. In one, acetone was absorbed from an air-acetone vapour mixture fed at atmospheric pressure to a bottom inlet section, water being fed to a top inlet section, a single stage 12 intervening. In another, an apparatus similar to that shown in Fig. 1 was used for the vacuum fractionation of mixtures of nbutyl ether and dichloroethyl ether. In a third, a mixture of 25 mol. per cent chloroform and 75 mol. per cent benzene was fractionated at atmospheric pressure.

Title: Improvements in or relating to Electronic Switching Networks
IPC: H04Q3/52
Filed: 1967-01-13
Abstract: 1,153,912. Automatic exchanger. SIEMENS A.G. 13 Jan., 1967 [14 Jan., 1966], No. 1903/67. Heading H4K. In a multistage-cross-point switching network marking potentials upon co-ordinate marking wires switch a cross-point four-layer transistor via a coincidence circuit at that cross-point. The provision of holding current for the transistor enables the marking potentials to be removed. In one arrangement the coincidence circuit comprises a resistor and two diodes each connected to one marking wire; in another arrangement a transistor is used having its base and emitter receiving marking potentials and its collector connected to the base of the crosspoint transistor. However in the arrangement shown in Fig. 7 where a subscriber T13 is connected to a connector Vs over cross-point fourlayer transistors KP1, KP2 and KP3, four-layer transistors SV are used as the coincidence circuits. Marking potentials Um1 and Um2 from co-ordinate marker wires render the transistors SV conductive to supply base current to the cross-point transistors KP which flows from this transistor over R4 or in the case of the first cross-point over Rt. The cross-point transistors are held by a current from source U1 in Vs when switch S closes, permitting the marking potentials to be removed. When neither transistor SV or KP at a cross-point is conducting the U10 source upon the p-doped emitter of SV produces a potential across the diode formed by the n and p doped base regions which as applied to the base of transistor KP reduces the capacitance of this base region and thereby the transistor's ability to conduct in response to interference pulses applied to the emitter from another connection path in the network. In other arrangements a separate diode is provided in the coincidence circuit for this purpose. The transistors AV, which are non-conductive when holding current flows in the connection path, indicate the state of seizure of the stages of the path. Diode SD2 or resistor Rs protect other transistors SV from overloading by source U10. The connection path provided by the crosspoints is broken down and crosspoints opened by cutting or reducing the holding current, such as by opening switch S or opening one crosspoint or by injecting a negative pulse into the path. A two-wire connection path is described (Figs. 8 and 9, not shown) where a pair of fourlayer transistors at a cross-point are switched by a single coincidence circuit comprising a three-layer transistor having one or two collectors connected to both or one of the crosspoint transistors. The formation of the switching network as integrated circuits is mentioned.

Title: A gyroscopic indicating or controlling apparatus in automatic pilots
IPC: G01C19/00
Filed: 1955-01-25
Abstract: 790,637. Electrical correspondence control systems. SVENSKA AEROPLAN AKTIEBOLAGET. Jan. 25, 1955 [June 22, 1954], No. 2175/55. Addition to 712,993. Classes 40 (1). [Also in Group XXIX] In a modification of the measuring device claimed in the parent Specification, means are provided for imposing a moment around the axis of the gyroscope housing, the moment being controllable in magnitude and the direction. When the apparatus shown, mounted on aircraft, ship or guided missile, turns in a vertical plane through the gyroscope output axis 6, 6, the gyroscope precesses about the axis and through the leaf-spring 35 and rods 36, 37 applies a moment proportional to the angular velocity of the apparatus on the beam 38 connected to an hydraulic damping and integrating device comprising a rotatable double wing 43 in which liquid may be displaced around the wings from one side to the other. The momentary position of a nozzle 10 exhausting actuating air from the gyroscope housing is therefore dependent on the angular position and the angular velocity and distributes air between the orifices 11, 12 leading to a piston 15 actuating a control surface 19. Hinged balance weights 29 cranked to an electrical moving coil instrument 23 move a vane 21 to modify the jet between the nozzle and orifices according to a signal proportional to the angular acceleration. An electrical signal received in coil 23, from an altimeter or target finding means according to the parent Specification also controls the position of the vane 21. Guiding of the missile is effected by electrical signals supplied to solenoids 59, 60 acting on armatures 57, 58 attached to the rods 36, 37 whereby the missile will turn at a speed depending on the current intensity in the coils 59, 60 and the magnitude of the turning is determined by the time the current is flowing. When the current ceases a spring 67 is positioned by a de-energized coil 62 releasing an armature 61 to engage the beam 38 for re-centralizing it and restoring the damping means to neutral position. The spring 67 also carries a weight 68 whereby a signal is imposed upon the beam 38 proportional to acceleration in the direction of the spin axis of the gyroscope, but because of the integrating member 43 the turning of the beam 38 will be proportional to the velocity of the mass 68.
