Title: Production of formed coke-like solid fuels from finely particulate bituminous coal
IPC: C10B53/08
Filed: 1954-05-28
Abstract: 753,084. Coking processes. KRUPPA, W. J., MACBARCLAY, K., and NOBLES, E. J. May 28, 1954 [May 28, 1953], No. 15904/54. Class 55(1). Coke is obtained from smelting coals of low sulphur and ash content by oxidizing the finely divided coal, forming with a binder a plastic mass which is shaped into elongated pieces and carbonizing the pieces by direct contact with a stream of non-reactive gas at a heating rate of 2À5-5‹C. per minute up to 600‹C. and À75- 1À25‹C, per minute up to the final temperature, e.g. 950‹C. The binder may be coal tar pitch and comprise 12À5-15 per cent of the mass, the moisture content of which may be controlled at 5-8 per cent ; a wetting agent e.g. an alkyl sulphonate may be included, and a small amount of water-soluble binder, e.g. waste sulphite liquor, molasses, starch dextrins may be added to increase the strength throughout the plastic range. Blends with unoxidized coals or additions of anthracite or coke breeze may be made to minimize fractures ; or the binder may be polymerized as by treatment with sulphuric acid. Dried pulverized coal is fed through a pump 2 and suspended in air from a compressor 4 passes through an oxidizer coil 8 in a furnace 9 and thence through a cooler coil 12 to a separator 15 and storage receptacle 16. The coal may be about 10-15 seconds in the oxidizer coil at a temperature of about 675‹-850‹F. From receptacle 16 it passes through a dryer 17 to a mixer 19 in which hot binder with steam preferably at about 325‹F. is sprayed on to it and water may also be added to yield a mix of 5-8 per cent moisture content. This is discharged into an extruder 23 from which a compacted tube of material is forced on to a conveyer 27 and cut up by a knife 26 into lengths and optionally by longitudinal knives, the pieces passing in the embodiment shown through a preheating furnace and heated to about 400‹C. before delivery to a retort. The pieces descend in countercurrent to two gas streams, one of products of the combustion of part of the retort gas and the other of another part fed through a line 36. If the preheater is omitted another stream of retort gas which is preheated may be introduced through a line 40. Tar and pitch are separated from the retort gas, and tar pitch obtained therefrom is employed as binder in the process. Specification 724,774 is referred to.
Patent GB-396202-A (GB)
Title: A method of converting polyphase current of a given frequency into alternating current of another frequency
IPC: B44C1/26
Filed: 1932-06-06
Abstract: 396,202. Frequency-changing ; phasechanging. AKT.-GES. BROWN, BOVERI, ET CIE, Baden, Switzerland. June 6, 1932, No. 15916. Convention date, June 4, 1931. [Class 38 (ii).] Relates to an arrangement for interchanging power between a polyphase circuit N1 and a single phase circuit N2 of lower frequency in which the two circuits are interconnected through two sets of grid-controlled discharge paths 1 .. 6 and 1<1>.. 6<1> associated with polyphase secondary windings on a transformer T, the amplitudes of successive phases of the latter being so graded, and the grids being energized in such sequence that the single phase current is approximately sinusoidal, and consists in simultaneously energizing corresponding grids in the two sets of discharge paths in order that at all times equal and opposite voltages are present in the local circuit comprising the two discharge devices. Thus the arrangement is capable of operating with inductive loads which would otherwise cause internal short-circuit conditions to be set up, and moreover is capable of transmitting power in either direction as determined by the relative voltage conditions in the circuits N<1>, N2. The grid energization may be effected by synchronously rotating switches U1, U2 serving to connect the appropriate pairs of grids in succession to the positive pole of a battery which is so connected as to maintain the grids normally at a negative potential with respect to the cathodes K1, K2. In a modification, Fig. 2, the two sets of anodes 1 .. 6 and 1<1> .. 6<1> are located in a common discharge vessel and the two circuits through which alternate half waves of the single phase current pass each contain a primary winding P1, P2 associated with a common secondary Q connected to the single phase circuit N2. In this case, a single switch U is employed for controlling both sets of grids. In a further modification, Fig. 3 (not shown), the discharge path 1 is arranged to pass current from the associated phase winding of transformer T to form the last portion of one half wave of the low frequency current and the first portion of the succeeding half wave, the grid control switch being modified to apply positive potential to the grid of discharge path 1 for a correspondingly extended interval.
