Filed: 1975-07-11
Abstract: 1501200 Removing HIS and mercaptans from gases RHONE-POULENC INDUSTRIES 11 July 1975 29260/75 Heading CIA Alkyl mercaptan and/or H 2 S are removed from a gas stream by (1) contacting the stream with an aqueous solution (pH 3-11) of (a) a chelate of a polyvalent metal (e.g.Fe) with where n = 1 to 3, X is acetic or propionic acid group, A is 2-hydroxyethyl, 2-hydroxypropyl or C 1-4  alkyl; or where 2 to 4 of X (same or different) are acetic or propionic acid groups, the remaining X (if any) being 2-hydroxyethyl, 2-hydroxypropyl or (X as in II); and R is ethylene, propylene, isopropylene or 1,2-N-substituted cyclohexane or bezene; and (b) an alkali metal, alkaline earth metal, ammonium or amine salt of an acid having pK a  at 25‹ C. of 1À2-6; (2) contacting the chelatecontaining solution with a gas containing molecular O 2 , and separating the resulting sulphur and/or dialkyl disulphides from the aqueous solution. The polyvalent metal is preferably Fe, Cu or Mn, using N-hydroxyethylethylene diamine triacetic acid (HEDTA) as chelating agent. Other metals and amino-acids are specified. Component (b) is usually sodium formate, but salts of other weak acids are specified. In Examples 1-31, air is added to H 2 S/N 2  mixture and the gas stream is fed to a chelate solution under conditions that ensure intimate phase mixing, the reduction and reoxidation of the chelate take place simultaneously. In Example 32, the chelate solution is mixed with H 2 S/N 2  and then regenerated with air, so that the redox reactions are sequential.

Filed: 1959-08-31
Abstract: Powdered B, Si, Te, predominantly less than 0,1n  in diameter is produced by thermal evaporation of the element at a pressure below 500n  Hg. abs. followed by condensation of the resultant vapours in a free space maintained at a pressure below 500n  Hg. abs.  The powder is then collected in an inert medium, e.g. hexane, heptane paraffin &c, or an inert gas.  A thin <PICT:0930402/III/1> oxide film may be produced on the powder by controlled oxidation or the powder may be reacted with hydrogen, a halogen, a Group VB element (other than nitrgen), or a Group VIB element (other than oxygen).  The Figure shows an apparatus for powder production in which an externally cooled vacuum-tight tank 10 is connected to a vacuum pump 13.  The required element is evaporated from a heated crucible 14 and condenses in the free space within the tank. Powder adhering to the tank walls is removed by a rotating brush and is collected with a collection chamber 22 containing inert medium.

Title: Improvements in coin-freed automatic delivery machines
IPC: G07F11/54
Filed: 1933-10-25
Abstract: 432,549. Coin-freed article-delivery apparatus. HARRIS, S., 99, Manor Road, Wallasey, Cheshire. Oct. 25, 1933, No. 29523. [Class 27] Articles stored in piles ; storage.-The topmost articles G<1>, Fig. 2, of a number of piles of articles G are delivered in succession to a shoot 12 and tray 13, the piles being stored in containers C equally spaced round a drum B which is rotated step-by-step to bring each pile in succession into alignment with the shoot 12. The piles are supported by hollow radial arms 10 extending from a base plate F which has threaded bosses 9 engaging vertical screws E. A wheel 8 on the bottom of the drum meshes with wheels 7 on the screws, so that the screws are rotated by the rotation of the drum to cause the plate F to move upwards and bring the top articles G<1> in turn into position for delivery. Instead of two screws geared to the drum, a single central screw fixed in the drum may be used. The drum is rotated by a pawl 16, Fig. 8, on an arm M engaging pins P on the drum, the arm M being carried by a vertical spindle 5 actuated by a hand lever K. Normally the lever K is locked in the position shown in chain lines in Fig. 8 by any known coin-freed mechanism. After insertion of a coin, it is rocked in a clockwise direction to rotate the drum through one step, and then returned to its initial position to deliver an article. The drum is positioned after each actuation by a spring-pressed vertical rod S engaging holes in the top of the drum and released to allow rotation by a cam rod T carried by a sliding frame Q. The frame Q is connected by a link 20 to the arm M and carries rods 21 sliding in brackets 22. A frame 23 carrying a pusher plate R to eject the top article G' slides on the rods 21 and is connected to the frame Q by a spring 28 always in tension. When the frame Q moves to the right in Fig. 8, a pawl 29 thereon pushes the slide 23 with it, until an inclined end on the pawl 29 meets a stop 34 which raises the pawl so that the slide 23 and pusher R are returned to their initial position by the spring 28 to allow the next column of articles to be moved into alignment with the shoot 12. Refrigerating.-The apparatus described is for the delivery of cartons, of ice-cream, Solid carbon di-oxide is stored in the hollow centre D of the drum and carbon di-oxide gas passes by flexible tubes H and the hollow radial arms 10 into the containers C which are corrugated longitudinally. The gas under pressure passes up the grooves in the containers to outlets at the top and maintains the ice-cream at a low temperature. The casing A of the apparatus is fitted with an inner cylindrical wall 14, the space between being packed with suitable insulating material. The slide 23 carries a stopper 45 which closes the opening to the shoot 12 except when a carton is being delivered.

Abstract: 744,716. Photo-electric apparatus for recording cloud data. BRISTOL CO. Oct. 31, 1953, No. 30142/53. Class 40 (3). [Also in Group XIX] A system for continuously recording the height and density of the cloud ceiling above a given point comprises an A.C. excited mercury arc lamp 10 in a reflector to produce a modulated beam of parallel light directed vertically, a distant photo-cell in a housing 15 which continuously scans the path of the light beam and a recording device with a pen-carriage 29 driven synchronously with the scanning movements of the housing 15, the pen 41 being deflected substantially normally to the line of travel of the carriage in accordance with signals received from the photo-cell. The photo-cell amplifier is tuned to the modulation frequency and so does not respond to steady light and the pen movement also may be tuned to this frequency. Accordingly when light reflected by mist, cloud, &c., from the light beam affects the photo-cell, the pen makes an oscillatory mark the amplitude and length of which are dependent on the density and thickness of the cloud &c. Instead of moving the carriage proportionally to the angle of elevation of housing 15, which gives a scale crowded at one end, a mechanical linkage may be provided to give a linear relation between the carriage position and the point on the light path being scanned, Fig. 8 (not shown). Instead of a single pen making an oscillatory mark there may be provided a pair of pens carried by scissors arms, Fig. 9, which are moved apart by a cam 78 controlled by rectified signals from the photo-cell. A single pen may alternatively be controlled by a torque-motor fed with rectified signals, or by a shaded pole torque motor. The oscillatory pendriving movements may be moving-coil, moving iron or piezo-electric.

Title: Improvements in and connected with the starting of motor converters
IPC: H02K47/04
Filed: 1926-11-30
Abstract: 281,863. English Electric Co., Dtd., and Schroeder, G. Nov. 30, 1926. Rotary transformers; field magnets, dampers on poles of. - In an arrangement for starting motor converters by producing a reduced flux in the alternating-current element of the converter, the pole-faces of the continuous-current element are provided with a winding or windings capable of acting during starting as the polyphase secondary coils of an induction motor. These may take the form of a squirrel cage which gives a high effective resistance at starting and serves as a damping winding after synchronizing. Fig. 1 shows windings 1, 3 which give a 2-phase effect in producing torque, the winding 1 serving as a compensating winding during normal running and being wound in the usual manner symmetrically with respect to the mid-polar axes and in series with the commutating-pole coils 2. The other winding 3 is symmetrical about the polar axes and is preferably in the same slots as the winding 1. As shown in Fig. 2, the windings 2, 3 form a 2-phase group connected through resistances 4, 5, preferably liquid, to the neutral point 7 and the negative bus-bar 6. The point 7 is also connected to the other end of the winding 3. The continuous-current armature of the converter is connected to the positive bus-bar 11 through a switch 10, and the field circuit 8, 9 is completed in the usual manner. For starting, the stator flux is reduced in the alternating-current element of the machine, the switch 10 is open, a switch 12 in series with the winding 3 closed and the resistances 4, 5 are inserted at full value. The resistances 4, 5 are then reduced and when normal speed is approached they are short-circuited, the stator flux is increased and the machine pulls into step. The switch 10 may then be closed and the switch 12 opened to convert the winding 3 into a damper. Thereafter, the windings 1, 2 act normally for commutating and compensating. The windings 1 and 3 may form a double squirrel cage with magnetic leakage between them or they may be wound in narrow deep slots or other means may be used to give a high effective resistance at starting. Also the commutator brushes may be lifted during starting.

Title: Jet propulsion engine structure
Inventor: WHITE HARLAN VERNON
IPC: F02K1/08
Filed: 1964-07-31
Abstract: 1,071,076. Jet propulsion nozzles. GENERAL ELECTRIC CO. July 31, 1964, No. 30323/64. Heading F1J. A frame structure for jet engines includes a generally cylindrical support member, which is adapted to carry an axial load distributed substantially uniformly about a circumference at one end of the support member, and a number of struts secured to and intersecting the support member adjacent the other end thereof, the support member having part of its curved surface slightly deformed so that this part contains a number of straight lines along which the axial load may be transmitted to the struts. Each of a number of struts 12 (one shown in Fig.1) is rigidly secured at 14 to the outer casing 10 of the exhaust duct of a jet engine and passes through a substantially cylindrical support member 30 which extends upstream and downstream of each strut at 32 and 34 respectively. A member 24, which forms the radially inner wall of the working medium flow channel, is secured to heat baffles 16 which shield the outer ends of the struts 12. A plug 40 is attached to and forms a continuation of the member 24. The plug 40 is supported by a member 38 which is rigidly secured to the downstream end of the support member 30 which is reinforced at 46, and the action of the engine exhaust gases on the plug imposes, through the member 38, an axial load on this reinforced end of the support member 30. Fig. 2 shows paths a, b-h and b'-h' along which the axial load is transmitted to the intersection of a strut 12 and the member 30. Were member 30 perfectly cylindrical, each of these load paths, except path a, would be curved and, consequently, any one of these curved paths would tend to flatten out before the axial load was transmitted therealong. Accordingly, the slight deformation of the support member 30 is such that an infinite number of straight lines are contained in the surface thereof in the triangular region extending between each strut and the downstream loaded edge of the support member, and the axial load is transmitted directly along these straight lines to the struts.
