Title: Process for purifying gases produced by the gasification of solid or liquid fossil fuels
IPC: B01D53/48
Filed: 1975-07-08
Abstract: 1483037 Purifying combustible gases METALLGESELLSCHAFT AG 8 July 1975 [29 Jan 1975] 28771/75 Addition to 1483038 Heading C5E The process for purifying a gas produced by the gasification of a solid or liquid fossil fuel in the presence of steam and/or oxygen under superatmospheric pressure described and claimed in the parent Specification is improved or modified by the steps of regenerating the scrubbing agent which has been used in the second scrubbing stage by flashing it approximately to atmospheric pressure, heating the scrubbing agent to the boiling temperature in the presence of sufficient water, if necessary, to ensure that the boiling temperature is not in excess of 170 C., treating the scrubbing agent in a stripping column with steam or stripping gas to remove the liquid impurities, condensing the mixed vapours, isolating the condensates by phase separation, feeding part of the aqueous phase as a reflux to the upper portion of the stripping column, cooling the stripped scrubbing agent and feeding it back for use in the second scrubbing stage. Embodiments of the regeneration procedure are described in detail. Organic solvents: N-methyl-pyrrolidone or other N-alkylated lactam, and polyalkyleneglycoldimethylether or other water soluble glycol ether having a boiling point below 200 C.

Abstract: 210,166. Medhurst, E. J. Oct. 26, 1922. Pulp, preparation of; pulping- engines. - In supplying pulp from stock to beaters or poachers, the pulp is out up transversely into strips by knives 3, 2, Fig. 1, and the strips fall on to a table 8. The table is fed forward by ratchet mechanism 9, and at the end of its travel is returned to its initial position by a weight 10, the strips being swept by a pivoted arm 11 on to a conveyer 12 and fed end-on to a similar cutter. The pieces so produced are delivered by a blower to a main pipe 16, Fig. 3, from which, by suitable valves 18, they may be fed to one or other of the hoppers 22 of a series of beaters 23. The hoppers 22 comprise fixed rods 27, Fig. 4, and rods 28 hinged at the middle. The latter are connected to a frame which may be raised to allow the pieces to fall between the rods into the beaters. A gate valve 24 opens when all the valves leading to the beaters are closed, thus admitting the pieces to a separate receptacle, which may be the receptacle to which they are fed from the cutters. A whistle 26 provides an audible signal of the opening of the valve 24.

Title: Improvements in visible indexes
IPC: B42F17/00
Filed: 1929-09-28
Abstract: 340,491. Visible card indexes. POWER, R. F., 18, Chesterford Gardens, Hampstead, London. Sept. 28, 1929. Nos. 29455/29 and 13606/30. [Class 146 (i).] A strip 1, Fig. 2, which may be an index strip or may form a support for an index card in a visible card index, is provided with a number of T, L, or equivalentlyshaped lugs of which one or more project from each edge so as to engage slots in a backing member. The slots 21 .. 25 may be formed in a sheet 20, the lugs 2, 3, 6 on the upper edge engaging the slots 21, 23, 25 and those 10, 11 on the lower edge engaging the slots 22, 24, thus preventing one strip overlapping adjacent strips. If desired, the sheet 20 may be attached to a backing sheet which is adapted to be bound in a book or loose-leaf binder or may be part of an endless band passing over rollers. In another construction, the slots are formed by ribbons stretched across rectangular frames hinged together similarly to covers, the frames being recessed so that the fingers may be inserted beneath the ribbons to insert or remove a card. A frame may be provided with slots on each face and mounted as a leaf between book covers. In a further construction, Fig. 19, the ribbons are attached at their ends to strips 78, 79 clamped between wood blocks 80, 81 arranged at the fold 82 of covermembers 76. Tongues 75 are struck-up out of the material of the covers 76 and are attached to the ribbons intermediate their ends so as to support them above the surface of the covers, the tongues being adapted to fall back into their original positions when the covers are closed and the ribbons lie along the covers. In a modified form of this construction in which the covers are made of metal, the strips 78, 79 are replaced by rods hinged together about an axis raised above the cover surface and the tongues 75 are replaced by hinged crank-members. The strips 1 may have widths corresponding to one or more lines of index matter, or may be formed integral with, or attached to, or adapted to carry an index card of a visible index. In the latter case the tongues are passed through slots in the card. Where the card is a double one 44, 45, Fig. 11, the tongues 2, 3, 6 are threaded through slots in the fold, and the tongues 10, 11 are threaded through slots 46 in the under sheet 45. The under sheet 45 may be only a narrow strip. The dimensions of the sheet or endless band 20, Fig. 2, and of the strips 1 are such that the sheet or band can be passed through a typewriter and the index matter printed on the strips. Further, the strips may be made as a series, Fig. 12, either in sheet or endless band form by stamping perforations from a sheet or web of paper and leaving the strips. connected by easily broken pieces 53 .. 55, the widths being arranged as before so that the index matter can be printed in a typewriter.

Abstract: 522,470. Rotary engines and pumps. FULCHER, F. C. Oct. 12, 1938, No. 29554. [Class 110 (ii)] Vanes 33 pass through slots in the rotor 18 which are closed at both ends to secure greater strength in the rotor. To permit assembly recesses 40 opposite the slots are formed in the inner surface of the rotor and grooves 39, Fig. 1, form gateways to the slots. The recesses 40 may be filled by pieces 41. Grooves 54 serve to lighten and, it may be, to balance the rotor. The swivel pieces 36 have each a slot open at one end and are inserted through holes in the end wall 35 of the rotor. The end wall 30 of the casing is described in Specification 522,473. The rotor, which is overhung, is carried by two ball-bearings 20, 21 and a spring sealing ring 24 is provided to protect the pump against oil spray coming from the engine 17 by which the pump is driven. The lubrication control 44 is described in Specification 522,471 and the flexible drive 25 in Specification 522,472, [Group XXIV]. The rotor may be held from axial displacement, due to wear, by means of a pointed setscrew inserted to bear laterally on the outer ring of the ball-race 21.

Abstract: 717,942. Open fireplaces. PAGE, H. H. March 18, 1953, [Dec. 18, 1951.] No. 29653/51. Class 126. A heat economizing device adapted to be fitted to an open fireplace, comprises a plurality of elongated strip-like reflectors, preferably polished on both sides, and means for fixing them one above the other to extend across the upper portion of the fireplace above the fret or grate bars in such a position that at least part of the radiant heat from the back of the fire which would normally strike the ceiling is intercepted and deflected into a generally forward direction. The device shown in Fig. 1 comprises a side member 1 at each side of the front of the fireplace frame 2 held in position by a rod located at each of its ends in an aperture 7 at the top of each member 1. The rod is screwthreaded at one end, a nut on this screw-thread being used to hold the members 1 in position by squeezing them against the frame. The reflector strips, preferably made from a light alloy and each made up of a broad and narrow strip 10, 11, span the distance between members 1 being pivotally attached thereto by brackets 8. If the strips are made flexible, such that they may be flexed and sprung into position in the brackets, thereby serving to exert clamping pressure, the rod may be dispensed with. In Fig. 3 the strips 10, 11 engage in slots 14 in side reflector panels 15, which are dished to stand proud of the side cheeks and seat on firebricks 16. A baffle 17, either secured to the strip or the panels 15, is provided to extend behind the top strip. This top strip may be arranged to close the top of the frame or, alternatively, a separate sealing strip may extend between the edges 18 of the panels. The baffle 17 may be replaced by the baffle 19, Fig. 4, the flanged ends 20 of which seat against the fireback behind panels 15 or bricks 16 with this cut-away portion 21 lowermost. Specification 238,673, [Class 126], is referred to.
