Filed: 1923-05-15
Abstract: 198,661. Dupuy, H. May 30, 1922, [Convention date]. Hydrocarbons, distilling.-In the distillation of solids, such as coal, or liquids, such as tar, the material is treated in a chamber a with superheated steam and the steam and distillation products are passed in a closed circuit through a condenser b by a fan c and back to the chamber a through a cooler d for residual products from the chamber a and superheater e. The distillation products are treated with a water spray f projected against a baffle h in the condenser b, the condensed liquids being collected in the vessel i. A branch pipe k removes the surplus products to a low temperature condenser m, the uncondensed gases escaping at o. The steam and gases entering the cooler d are re-heated by contact with the hot residues from the chamber a and pass into the superheater e before entering the chamber a. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of gas as a distilling agent. This subject-matter does not appear in the Specification as accepted.

Patent GB-754966-A (GB)
Title: Cracking or coking heavy hydrocarbon oils
IPC: C10G9/32
Filed: 1954-05-07
Abstract: <PICT:0754966/III/1> <PICT:0754966/III/2> In a process for cracking heavy hydrocarbon oils in the presence of a dense fluidized bed of hot non-catalytic solid particles, the feed oil is injected into a mixing zone through which a suspension of the solid particles is moving rapidly in highly-turbulent flow, whereby uniform distribution of the heavy oil on the particles is effected; the coated particles are then discharged into the dense fluidized bed.  The mixing zone may be disposed either inside or outside the dense fluidized bed. Gasoline, unsaturated hydrocarbon gases and coke may be obtained as products.  Suitable inert solids are coke, sand, pumice, alumina, and spent cracking catalyst.  A residual oil (I.B.P. 1150 DEG F.), is preheated to 600 DEG F. and introduced through line 18 (Fig. 1), into riser 22 which is part of a U-shaped passageway connected to reactor 10.  In the reactor is maintained a dense fluidized bed 12 of coke particles, the temperature being 900 DEG -1100 DEG F. when it is desired to produce gasoline.  Actuated by steam introduced through line 28, hot coke particles pass down standpipe 26 and up through riser 22. Standpipe 26 is provided with fluidizing line 62; and the bottom of U-bend 24 may be aerated by introducing gas through line 64. An intermediate section of riser 22 is provided with a venturi 32 (Fig. 2), which is perforated, slightly downstream of the maximum constriction, with openings 40 leading from nozzles 38, manifold 36 and line 18.  The oil is injected through openings 40 and is uniformly distributed on the turbulent coke suspension as it moves rapidly through the venturi.  Oil may also be introduced into riser 22, above and below the venturi, through lines 42 and 44. About 5 weight per cent of steam, on the oil fed through line 18, is introduced through line 28.  Steam may also be introduced into the riser through line 54.  The oil/coke mixture flowing up through riser 22 is discharged into reactor 10.  The cracked products leave the top of the reactor via cyclone 56, and are submitted to fractionation. Coke particles are withdrawn from the reactor through line 66, and are stripped of volatile hydrocarbons in stripper 68.  The hydrocarbon-laden gas from stripper 68 is passed to the reactor.  The stripped coke particles are mixed with air introduced through line 74, and the mixture is passed into burner 48, which may be of the dense bed type or the transfer line type.  In burner 48 the coke particles are raised to a temperature between 1100 DEG  and 1600 DEG F. due to partial combustion.  The hot coke particles are returned via lines 49 and 78 to the bottom of the dense bed in reactor 10. Some of the hot particles may be passed through lines 50 and 52 to riser 22 and standpipe 26.  When more coke is being produced than is necessary to supply heat to the reactor, it is withdrawn as product coke through line 72.

Abstract: 930,811. Packages. W. N. JARDINE. April 14, 1961, No. 13483/61. Class 94(1). A container, Fig. 10, is made from a blank of flexible material longitudinally heat-sealed at 16, the resulting tube being transversely sealed at 18, filled, and sealed at 20 to close it, thereby producing the container of Fig. 4 Which is then applied to a support member 26, Fig. 6, in order to form flaps 28, 30 subsequently folded inwards and sealed. In forming the base the weight of the contents is sufficient to deform the tube walls, and the flaps 28, 30 which are folded in as the support member 26 is withdrawn, are sealed by a separate strip 32, Fig. 9. The tube may be extruded instead of being formed from a blank. A straw 22 may be inserted in the tube at the time of filling. In a modification, Fig. 11 (not shown), the flaps 28, 30 are turned outwards and sealed to the container side wall. Alternatively, Fig. 15 (not shown), the end flaps may be turned out to form basal flanges, heat-sealed over their surfaces in that position, and trimmed, thereby making the container more stable. The top seam 20 may be scored or weakened to provide entry to the container. The container may be formed of separate plies of plastics material and paper, which may be laminated, Figs. 18- 23 (not shown). The material of the container may be transparent or translucent.

Title: Signalling on Primaries of Telephone or Telegraph Phantom Circuits.
Inventor: RITTER EDWARD STANTON
IPC: H04M7/08
Filed: 1918-08-20
Abstract: 130,489. Ritter, E. S. Aug. 20, 1918. Simultaneous telegraphy and telephony; multiplex telephony.-Relates to arrangements for transmitting steady current signals over the individual wires forming loop telephone or telegraph circuits upon which one or more phantom circuits are superposed. The loop circuits A, C are connected by transformers D, E to the pairs of wires X, Y upon which a phantom circuit B is superposed over transformer F, and the transmitting or receiving apparatus, by which steady current signals can be sent over the four individual wires of circuits X, Y with earth return, are connected to the four points 29, 30, 31, 32. In order to enable independent, signals to be sent over the wires x, x<1>, which are usually connected together in the loop circuit transformer, a condenser : i is arranged as shown, a condenser j being similarly associated with transformer E and circuit Y. The line side of transformer F has four windings, of which two connect the circuit X over points 9, 11 to leads 10, 12, while the other two connect circuit Y to leads 15, 17. The leads 10, 12, 15, 17 are interconnected in pain by condensers k, l, m, n, o, p, which provide a path for the alternating currents of the phantom circuit. Impedances q, r, wound to be inductive to currents in the loop circuits X, Y, and an impedance s wound to be inductive to currents in the phantom circuit are connected between the leads 10, 12, 15, 17 and the terminals 29 - - 32 of the steady current signalling-apparatus. These impedances keep the currents of the loop and phantom circuits out of the steady current signalling-apparatus and also prevent too rapid change of the signalling- currents. A signalling-current applied, for example, to terminal 29 passes through impedances s, q, lead 10, winding of transformer F, points 9, 4, winding of transformer D to point 3 and wire x<1>. Instead of, or in addition to, the impedances q, r, s, impedance coils may be inserted in the leads 10, 12, 15, 17. Alternative arrangement of the condensers k - - o also are described. When a phantom circuit is to be superposed on two phantom circuits, the latter are arranged as shown in Fig. I. and the superphantom circuit is connected to terminals 43, 54, Fig. IV, of a transformer H having eight secondary windings, the terminals 35, 37, 39, 41 of which are connected to terminals 29 - - 31, Fig. I, of the first phantom circuit, and the terminals 46, 48, 50, 52 are connected to corresponding points of the second phantom circuit. The terminals 36, 38, &c. are connected to the steady current signalling-apparatus through condensers, similar to condensers k - - o, Fig. 1, with or without impedance coils. A modified arrangement for a phantom circuit with an earth return superposed on a phantom circuit is described. The Provisional Specification describes alternative arrangements of condensers.

Filed: 1927-05-23
Abstract: 295,756. Eyston, G. E. T. May 23, 1927. Fixed-abutment type.-In a rotary pump of the type comprising an eccentric rotor with vanes projecting through openings in the rotor or sliding through rocking bearing blocks in the rotor periphery, the rotor is driven or the bearing blocks are rocked by members distinct from the vanes, and the centrifugal action on the vanes is taken up independently of such members. As shown in Fig. 1, the bearing blocks h are extended at one end of the rotor and have rigidly secured thereto links u which are slotted to engage an extension z on a shaft k centrally situated in the pump casing around which the vanes g are constrained to move being hinged or rigidly connected to rings r, which may be mounted on ball or roller bearings, encircling the shaft k. Lubricant may be supplied to the chamber 4 containing the links u and fed to ducts 9 in the rocking bearing blocks h by an oil deflecting ring 10. Fig. 4 shows a modification wherein the bearing blocks h are rocked by rods 11 projecting through holes 14 therein and at their inner ends formed with rings 12 encircling the central shaft; the rotor is formed with an extension 15 to form a chamber 16 containing the rods to which lubricant is supplied by a pipe 17; the vane spindles s may be extended at s<1> to join the rods 11. The vanes may be constrained to move round the central shaft by loose rings 32, Fig. 10, which are engaged internally by rollers 31 on the vanes and at the diametrically opposite position engage the central shaft k<2>. Figs. 16 and 18 show arrangements o: intermediately situated members for controlling the rocking bearing blocks : the first consists o: two angularly bent bars 48 screwed to the block and embracing the central shaft; the second comprises a forked member 50 which projects through slots 51 in the bearing block distinct from the vane slot and is rotatably mounted on the central shaft. By reason of the positive rocking of the bearing blocks the vanes, if rigidly mounted, may work with a uniform clearance in their slots. The vanes may slide directly through the rotor slots and rocking bearing blocks be provided for the guide members only. When the pump is arranged vertically, Fig. 6, thrust bearings 21 are provided for the rotor and the rocking bearing blocks h<1>, which latter are actuated by plates 19 which, together with the vanes, are rigidly fixed on counterweighted rings 22 rotating on the central shaft.
