Title: Improvements in and relating to coking
IPC: C10B55/00
Filed: 1955-12-08
Abstract: 774,668. Coking. UNION CARBIDE & CARBON CORPORATION. Dec. 8, 1955 [Dec. 9, 1954], No. 35222/55. Class 55 (1). Pitch-like material is coked continuously by feeding the material in molten state to a pool thereof maintained at a coking temperature removing by mechanical entrapment that part of the contents of the pool which has been coked to such an extent that it resists gravitational flow, moving the partly coked material slowly through an additiona. coking zone to complete the coking, and discharging the coke. The molten pitch enters a shell 11 from a feed pipe 12, and wells over the lip of a funnel 15 supported on an inner wall 14. Scrapers 17, rotated by a shaft 21, prevent clogging of the surfaces. Heaters 27 are arranged on the shell 11 and the wall 14, and a drain 26 is provided. The pitch collects as a pool, at the bottom of an inclined casing 32, from which partially coked material is dragged up the lower wall of the casing by flights 33 on an endless chain 34. The upper run of the conveyer is supported on a guide 38. As the flights leave the casing 32 they are aligned with an opening 42 which conforms with the shape and size of the flights. With a similar opening 42 for the re-entering flights, this arrangement prevents the escape of volatiles which are drawn off at 44. Strip heaters are attached to the outside of the casing 32 to heat the pool and to complete the coking. The coke is discharged from the flights into a hopper 46, the coke being dislodged from each flight by a member 49 which is slotted to move down on each side of the chain and push the coke from the flight. The member 49 is operated by fluid-operated cylinders in timed relation with the flights.

IPC: F23J1/00
Filed: 1953-12-21
Abstract: 737,368. Separating dust from gases. RESEARCH CORPORATION. Dec. 21, 1953, No. 35489/53. Drawings to Specification. Class 8 (2). [Also in Group XL (a)] A method for the recovery of fly ash from combustion gases comprises introducing finely powdered coal particles into the combustion gases, and then subjecting the gases to mechanical cleaning and electrostatic precipitation. The coal particles are preferably less than 10 microns in size, and are added in the proportion of 10-20 per cent by weight of the fly ash content of the gases. In a powdered coal boiler system the coal particles are derived from the coal pulverizer supplying powdered coal to the boiler.

Abstract: 412,500. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London. -(Assignees of Bird, L. T. ; 211, St. Sacrament Street, Montreal, Canada.) Dec. 19, 1933, No. 35718. Convention date, April 22. [Classes 40 (iii) and 40 (v).] When a transmitter is connected to an aerial by a feeder, overloading of the transmitter due to initial mismatching of the aerial tuning and coupling device is .presented by the use during adjustment of a resistance network which serves both as a dummy load and as a bridge for testing the impedance of the aerial. The transmitter is connected through a feeder to the terminals T1, T2, and so to a network composed of resistances as shown in Fig. 3, where each resistance is equal to the characteristic impedance of the feeder, and during adjustment of the transmitter the galvanometer branch G is broken while a further resistance, equal to each of the others, is connected across the terminals H1, H2 (Fig. 2, not shown). Under these conditions the network is matched to the feeder at terminals T1, T2. The aerial is next connected across terminals H1 and H2 and its tuning and coupling device is adjusted until the galvanometer G indicates that the bridge is balanced. Finally the aerial is connected directly to the feeder at terminals T1, T2. The resistances shown as separate may be replaced by a smaller number of resistances having an equivalent effect (Fig. 1, not shown).

Air filtering elements 13 are cleaned by reverse flow pulses of compressed air delivered through nozzles 42 which are located within the elements so that the flow through the end outlets 12 is not reversed during cleaning. Nozzles may be frusto-conical, ample tubes, perforate tubes or bell-shaped with possible openings in top and side wall (Figs. 4 to 7, not shown). Other constructions, not illustrated, are perforate cylindrical boxes, or arrays of nozzle pipes extending from respective tubes 41. Nozzles are connected in groups for sequential cleaning of corresponding elements, to which single or multiple pulses are delivered by timer-controlled, solenoid-operated valves 43 (Fig. 2, not shown). Filtering flow is inwards through elements 13 and is effected by upstream and/or downstream fans. Dust discharge valve 17 may .be replaced by a bin or polyethylene bag to collect dust. The element 13 comprises a welded mesh frame with an upper spigot and gasket and a lower closure, urged upwards against plate 11 by a clamping screw beaming on a horizontal support 35 (Fig. 3, not shown). A filtering sleeve of wool or polyester felt, nylon or cotton is secured round the frame by hose clips. The housing 10 has an access door for replacing elements and is divided by partitions between groups of elements.

Abstract: A flexible, porous, asbestos-fibre, paper sheet comprises 90-99% by weight of milled hard asbestos fibre and 1-10% of binder material, and has a bulk of at least 0.30, where bulk is one hundred times the caliper in inches divided by the weight in pounds per hundred square feet.  The paper is made from a pulp in which the milled asbestos fibres consist of chysotile, crocidolite or amocite fibres and are of such a size that at least 70% by weight of the fibres are retained on a 200 mesh (U.S. Standard) sieve, and at least 50% of those retained on the 200-mesh sieve are retained also on a 100-mesh sieve.  The binder may be polyvinyl chloride, polymers of the methyl, ethyl, butyl or hexyl esters of acrylic or methacrylic acid and mixtures and copolymers, or cellulose ethers or esters.  The sheet may also contain fillers or pigments such as titanium dioxide, carbon black, silicon dioxide, rouge or heavy metal pigments.  The paper can be readily impregnated with synthetic resins of high viscosity, e.g. phenol-aldehyde, unsaturated polyester, or epoxy resins, by passing it through a tank containing the resin solution, then between squeeze rollers and heating to dry and partially cure the resin.
