Title: Method of operating blast furnaces
IPC: C21B5/00
Filed: 1937-06-12
Abstract: 497,264. Manufacture of iron ; ferroalloys ; non - - ferrous metals ; motorpower plant. AVERY, J. M. June 12, 1937, No. 16371. Convention date, June 12, 1936. [Classes 72 and 82 (i)] [Also in Groups XII and XXVI] In the operation of a sealed blast furnace for the manufacture of iron and ferro-alloys, the average static pressure within the furnace is maintained at between two and seven atmospheres gauge, by supplying the blast feed gas at super-atmospheric pressure and throttling the gas discharge from the furnace so that the deficiency of hearth heat and the gasefication loss is decreased whilst the output of the furnace is increased. The blast-feed rate may be increased by about half of the proportion by which the average absolute static gas pressure within the furnace is increased over the normal gas pressure so that, e.g. by increasing the blast feed to about twice the normal rate. the gas pressure within the furnace is increased to about four times the usual pressure. The blast feed gas may be compressed, cooled and, if desired, heated by the heat of the discharged gas. The pressure within the furnace 10 is controlled by a throttling valve 19 in the gas-discharge pipe 20 and a control valve 14 in the feed pipe 13 to the bustle pipe 12. The blastfeed is passed through a compressor 15, a cooler 16, a dehydrator 17 and preferably through a stove 18 heated by gases which are byepassed from the pipe 20 by a pipe 26 The discharged gases are passed through a dust catcher 21 and then through a decompressor, such as a turbine 22 which may drive the compressor 15. A portion of the decompressed gas may operate an internal - combustion engine 25 connected through differential gearing 23, 24 to the compressor 15, and the remainder of such gas led by a pipe 27 to a boiler. In a modification the engine 25 may be supercharged by air byepassed from the blast pipe after leaving the compressor 15. The Specification as open to inspection under Sect. 91 states that the furnace may be used for the production of non-ferrous metals which do not volatilize under the conditions of operation described above. The subjectmatter does not appear in the Specification as accepted.

Title: Cementing equipment
IPC: E21B17/14
Filed: 1959-05-13
Abstract: 846,698. Drilling wells. SERVICE Inc., B. J. May 13, 1959 [May 13, 1958], No. 16478/59. Class 85. Apparatus for metering the admission of well fluids to a casing string as it is run into the well, and for preventing cement slurry from running back into the casing string when the pump is stopped, comprises metering means 3 and a separate back-pressure valve means P which is pumped down into the casing by the cement body 441 and locks on to the means 3. The metering means is shown as incorporated in nose 2, but may be in a cementing collar above the bottom of the casing C. It consists of a cylindrical rubber or like body 5, reinforced by a metallic core 8, and having at its top a centrally apertured diaphragm 6 which, when unstressed, has a flat upper surface. Jammed between the body 5 and the flange 10 is a ring 12 which is connected at one side to, and may be integral with, a flap member 13 having a central apertured metal insert 15. The flap rests on the diaphragm 6, but when an upward fluid surge occurs the flap 13 lifts and the diaphragm 6 yields upwardly to permit the fluid to pass into the casing to a controlled extent. When the casing is fully lowered, flushing liquid is pumped into the well, the pressure on the top of the body 5 and flap 13 ejecting these members from the bore 4. After flushing, the back-pressure plug means P is forced into the well casing by the cement plug 441 which is separated from the flushing fluid by the plug P. A plug T may be used as a separator between the cement and another fluid from the pump. The plug P includes a resilient body 42 having sealing ribs 43, 44 which body seals against a taper seat 19 on a ring 18. A taper nose 45 on the plug P expands a spring-ring 25 which snaps into a recess 20 to lock the plug P and metering device together. The bore 40 is, during the approach of the plug P to its locked position, closed by a plug 41, but when the plug P is arrested, pressure in the cement plug 441 rises, the cement passes ribs 38 and ejects the plug 41 to the bottom of the well. Pumping proceeds until the plug T is arrested against the plug P, the pressure rise indicating this. The pump is stopped and the back pressure forces the ball valve 39 against its seat to prevent back flow of cement. Fig. 12 shows a modified form of metering device, a strainer disc 51 being retained in the bore 41 by shear pins 50. The resilient diaphragm 55 is free to yield upwardly with upward fluid surges, but seats on the concave face of the strainer, with downward pressure, substantially to seal it against passage of fluid. The downward pressure thus shears the pins 50 and the members 51, 55 are ejected from the bore 41.

Title: Improvements in or relating to production of n,n-dialkylamino alcohols
IPC: C07C215/08
Filed: 1944-09-01
Abstract: An N,N-dialkylamino alcohol is produced by reacting a non-halogenated aliphatic polyhydric alcohol having at least one primary and at least one secondary carbinol radical with a secondary aliphatic amine in the presence of a metal oxide-containing or metal hydrogenation catalyst at a temperature of at least 120 DEG  C.  Reaction may be effected in liquid phase at 120-180 DEG  C., but temperatures up to, for example, 250 DEG  C. may be used.  1,4-Pentanediol and diethylamine yield N,N-diethyl-1-amino-4-pentanol which, with ammonia or thionyl chloride respectively gives 5-diethylamino-2-amino (or chlor) -pentane which are intermediates for the production of antimalarials.  Other polyhydric alcohols used include propylene glycol, 1,2- or 1,3-butanediol, and 1,3-or 1,4-pentanediol and other secondary amines are di-methyl, -ethyl-n-propyl, -isopropyl and -butyl amines.  Hydrogenation catalysts include Ni, Pt, Pd, Co and Cu, copper oxide, platinum oxide and hydrated alumina which may be on carriers.  In examples, 1,4-pentanediol, diethylamine and a catalyst made by decomposition of nickel formate in mineral oil, which catalyst may first be washed with ethanol, are autoclaved while stirring at temperatures between 150 DEG  and 180 DEG  C., and the N,N-diethyl-1-amino-4-pentanol fraction recovered. This may be converted to 5-diethylamino-2-amino-pentane by autoclaving with anhydrous ammonia and a nickel catalyst at 200 DEG  C.
