Title: A container for corrosive liquids
IPC: B01J19/00
Filed: 1963-06-07
Abstract: 1,001,315. Corrosion - resistant containers. E. I. DU PONT DE NEMOURS & CO. June 7, 1963 [June 22, 1962], No. 22859/63. Heading B1X. [Also in Division F2] Containers for corrosive fluids comprise an exterior supporting casing and a spaced internal lining of polymeric material, spacing and support means occupying 3-50% of the space between the casing and lining, means to introduce a purge gas to and withdraw said gas from said space, and deflecting means to guide the gas uniformly between the casing and lining. The spacing and support means may comprise studs which are sealed into or integral with the inner wall and may be threaded, passed through the outer wall and suitably held in place. Metal rivets may be employed, the heads lying inside the inner lining and protectively coated with polymer. As shown in Figs. 3 and 6, however, the spacing and support means are parallel ribs separated by gaps 8 on the outer surface of the inner lining. The purge gas is distributed from an inlet such as 7 to manifolds 6 formed by omission of ribs. As shown, the purge gas, e.g. air or nitrogen, is separately circulated to the head 1 and base 2. Purge gas is discharged from the base at 7. The gas may be supplied under pressure to assist in the support of the lining, or the spaces may be filled with a highly permeable support material such as asbestos. The container may be heated or cooled by an external heater or cooler which concurrently heats or cools the purge gas, or the gas alone may be heated or cooled, or heating or cooling means may be provided between the liner and casing. The lining may be fabricated from polyethylene, polypropylene, polystyrene, polyvinyl chloride, polycarbonates, polyoxymethylenes, polyamides, chlorinated polyethers and especially polymers of tetrafluoroethylene, tetrafluoroethylenehexafluoropropylene, vinylidene fluoride and chlorotrifluoroethylene. The outer casing may be of metal or of rigid polyethylene, polypropylene, polystyrene and copolymers of styrene, and polyoxymethylenes, polycarbonates and polyamides or of thermosetting resins or reinforced plastics.

Title: Method and means for preventing leakage of gases from furnaces, especially in steam boilers
IPC: F23M11/02
Filed: 1925-09-29
Abstract: 240,497. Roucka, E. Sept. 29, 1924, [Convention date]. Air supply and draught, regulating. - In means of the kind described in Specification 230,061 for automatically regulating the pressure in the flues of a furnace with forced bottom draught, to prevent leakage of gases into the outer air, connection to a pressure-sensitive member is established at a point in the flues such that the static pressure, difference between the columns of air and flue, gases extending from the fire-box to the connection is either equal to or greater than the greatest possible dynamic pressure drop of the flue gases between the firebox and the connection. The ash-pit damper 8 of a boiler furnace 2 is regulated automatically or by hand in accordance with the load, and the smoke-flue damper 16 in accordance with the pressure of the. gases at the connection 18 in the flue 12, or vice versa if desired. From the connection 18 a pipe 20 leads to the underside of a bell float 22 suspended by a rod 26 from a balance beam 28 and counterbalanced by a spring 32 which can be adjusted by a setting-member 34 to determine the negative pressure to be maintained at the connection 18. Increase of pressure in the fire-box 10 and therefore at the. connection 18 raises the bell 22, rocking a beam 28 so that a rod 36 actuates the valve gear 38 of a servo-motor 40 which through a cord 42 opens the damper 16 until the desired negative pressure is again produced at the connection 18. The correct position of the connection 18 to fulfill the above conditions mav be determined empirically. Instead of a damper being adjusted, the motor driving a blower may be directly regulated.
