Title: Method for drying gases
IPC: B01D53/26
Filed: 1967-09-09
Abstract: A method for drying wet industrial gases by contacting them with a refrigerated inorganic brine is shown. The wet gas is contacted with cold brine and water vapor is condensed from the gas into the brine. In a preferred method, two stages of gas-liquid contact are employed to produce a particularly dry gas product. Brine used in the first contacting zone is heat exchanged with colder brine used in the second contacting zone and, if desired, it may be heat exchanged with dry cold gas product from the second zone before recycle to the first zone. Brine from the second zone is subjected to refrigeration before recycle to the second zone. Drying is carried out in conventional packed towers, at low pressure, and does not require system regeneration or replacement of expensive adsorbents.

Patent ES-348993-A1 (ES)
Title: Process for improving the quality of a carbon black oil
IPC: C09C1/50
Filed: 1967-01-05
Abstract: A low quality carbon black oil is upgraded, i.e. its asphaltene content is decreased for a given correlation index (which is defined), by subjecting the oil to vacuum flash distillation at 10, thermally cracking the overhead at 12, recovering a tar at 16 from the cracking step, and blending the tar with the bottoms 13 from the distillation step. The low quality oil may be the thermal tar from the conventional thermal cracking of a virgin gas oil, see Figure, or the thermal tar manufactured from synthetic tower bottoms and cycle gas oil from a catalytic cracking unit. The process is applicable to hydrocarbon oils having a 5% point of 425 to 600 F, and the bottoms 10, 13 respectively have 5% points of 800 to 900 F. and 500 to 600 F. Cracking conditions are: pressure 150 to 1000 p.s.i.g., outlet temperature 800 to 1000 F., and in two examples the cracking residence times were 2À5 and 2À2 hours.

Patent ES-355704-A1 (ES)
Title: Centrifugal condensing apparatus
IPC: B04B15/00
Filed: 1968-07-03
Abstract: A solution is concentrated by evaporation in chamber 5 within a rotary casing 1 from the inner wall 3 of which project a series of annular, heatable blades 6a . . 6l which define, in conjunction with wall 3, a series of annular channels 7a .. 7l connected in pairs of passages 8a . . 8f formed along the radially outer edges of alternate blades 6a, 6c ... The radial length of the successive blades decreases in the downward direction. In the evaporator as shown, the blades are hollow, and steam for heating the blades is supplied to chamber 4 through duct 15 and the condensate, driven out of the blades by centrifugal force, is discharged from chamber 4 through nozzle 19 into spiral trough 20. It is mentioned that the blades may be heated in a different manner, e.g. by electrical means. The solution to be concentrated is fed through nozzle 9 into channel 7a, flows by centrifugal force outwardly over the upper surface of blade 6a and passes through passage 8a into channel 7b between the hot surface of blades 6a and 6b. When channel 7b is full of solution, channel 7a is still not quite full since blade 6a is longer than blade 6b. Thus further flow of solution into channel 7a causes the solution in channel 7b to overflow over the radially inner edge of blade 6b. This overflow is urged by centrifugal force along channel 7c and thence through passage 8b into channel 7d. This alternate inward and outward movement of the solution continues down the evaporator. While thus flowing in the channels between the hot blades, the solution is caused to boil, and the vapour which is given off leaves the solution as it flows over the inner edges of blades 6b, 6d ... The vapour flows out of the evaporator through duct 10 which is connected to a centrifugal condenser 21. Concentrated solution is forced out of the evaporator through channel 7m and nozzle 13 into spiral trough 14. In a modified design, the length of each non-apertured blade is the same as the length of the apertured blade beneath it. Several evaporator chambers can be arranged along a common axis of rotation, with the solution passing from one chamber to another in series, while the solvent vapour given off in each chamber (except the last) is used to heat the next chamber.

Both types of ether are formed, and they are separated by chromatography. In the products, esterified OH groups may be hydrolysed, 17-ones may be converted to 17[alpha]-R 1 - 17#-ols (R 1 is H or an aliphatic hydrocarbyl or halohydrocarbyl radical), free OH groups may be esterified or etherified, and a 17[alpha]-ethynyl group may be converted to a 17[alpha]-(211,211-difluorocyclopropenyl) group. Starting materials of the Formulae (D) and (E) below are prepared from precursors of the formula (C) as indicated, the precursors being prepared from reactants (A) and (B) as indicated wherein R 1 is H, CH 3 , OCH 3 , OH or O acyl, R 2 is H or CH 3 and R 6 is CH 3 or C 2 H 5 . The preparation of compounds (C) proceeds via 2-R 6 -2- (1,2,3,4 - tetrahydro - 6 - methoxy - 3 - R 2 - 8 - R 1 - naph - 1 - ylidenethyl) - cyclopenta - 1,3 - diones and 3 - methoxy - 13 - R 6 - 1 - R 1 - 7 - R 2 - estra- 1,3,5(10),8,14 - pentaen - 17 - ones, which lastnamed are catalytically hydrogenated to give the corresponding 1,3,5(10),8 - tetraen - 17 - ones and these reduced to give (C). The process (C) -> (D) proceeds via the estratrien-17#-ols, and the process (C) -> (E) proceeds via the 8,9 - oxido - 1,3,5(10) - trienes, the 8[alpha] - hydroxy- 1,3,5(10),9(11) - tetraenes, the 8[alpha] - hydroxy- 1,3,5(10) - trienes, 17 - mesylates of the 1,3,5 (10),7 - tetraenes, the corresponding 17 - ols and the corresponding 3,17-diols. The steroid ethers of the invention are stated to possess anti-fertility and estrogenic activity, and they may be made up into pharmaceutical compositions with suitable carriers.

Title: Check valve with restricted bypass flow
IPC: F16K15/00
Filed: 1969-06-04
Abstract: A valve, which provides a relatively unrestricted flow in one direction and a comparatively restricted flow in the opposite direction, comprises a casing 10, two juxtaposed plate members 20 and 30 which are retained between casing shoulders 16 and 18, and a freefloating valve member 24, the two plate members being formed with aligned central apertures 22 and 32 respectively and the plate member 30 being additionally formed with a spiral throttling groove 34 which extends between aperture 32 and one of a number of peripheral recesses 36. In operation, fluid flowing from aperture 22 to an aperture 12 formed in the casing 10, tends to force valve member 24 against a plurality of projections 14 such that a relatively unrestricted flow takes place through apertures 22, 32, through channels formed between the valve member 24 and the projections 14, and finally through aperture 12. Upon the direction of flow being reversed, valve member 24 is caused to engage plate member 30 and a restricted flow takes place from aperture 12, through the one recess 36, through the spiral groove 34 and finally through the apertures 32 and 22. Figs. 6 and 7, not shown, indicate possible modifications of the throttling groove. Figs. 8 to 11, not shown depict a modification of the valve which includes, inter alia, an additional passage radially offset with respect a central passage corresponding to passage 22, the central passage having fluid flowing therethrough only in the unrestricted direction whilst being blocked by the valve member when such flow is reversed, with the fluid flowing through the valve, upon such flow reversal taking place, leaving the valve via the additional passage subsequent to passing through the restricted passage.

Patent ES-388796-A1 (ES)
Title: Columbium treated low carbon steel
IPC: C22C38/12
Filed: 1971-03-02
Abstract: A process of producing non-aging, low carbon steel having substantially no yield point elongation in the annealed condition and freedom from critical grain growth. A molten steel having an analysis typical of steel intended for rimmed or killed drawing steel is vacuum degassed to decarburize to a maximum carbon content of about 0.015%, and columbium (niobium) is added in an amount at least sufficient to combine with the carbon present in the steel. The cast material is hot rolled, finishing at 1500 DEG - 1700 DEG F (about 1090 DEG - 1200 DEG K) and coiled at a temperature of about 1500 DEG F (about 1090 DEG K) or less. The columbium addition retards the rate of recrystallization of the cold rolled product, and a wide spectrum of mechanical properties can be obtained in the final product by control of the final annealing time and temperature within the range of 1000 DEG to 1700 DEG F (about 810 DEG to 1200 DEG K). A preferred product is cold rolled and annealed strip suitable for deep drawing, porcelain enameling, hot dip metallic coating and the like, containing at least about 0.025% uncombined columbium at the hot rolling stage, as determined by analysis at room temperature, which has an average plastic strain ratio of at least 1.8, and a uniform grain size between ASTM 8 and 10.

Patent ES-408033-A1 (ES)
Title: Integral turbo-compressor wave engine
IPC: F02B33/42
Filed: 1972-10-20
Abstract: The present engine includes a heating chamber to produce relatively high temperature, high pressure gases an intake chamber to provide relatively low temperature, low pressure gases which initially act as scavenging gases an exhaust chamber into which the spent hot gases are expelled by the scavenging gases a compressed cool gas chamber into which the compressed cool gases flow with partial expansion and at least one hot gas expansion outlet or duct into which the high pressure hot gases expand. In addition the present engine includes a compressor-expander rotor having a plurality of rotor chambers, with each of said rotor chambers having an inlet opening and a nozzle with an outlet opening. The compressor-expander rotor is disposed to rotate adjacent to said intake chamber and said heating chamber, to accept into said rotor chambers, cool gases from the former followed by hot gases from the latter. Termination of the flow of cool intake gases from each rotor chamber nozzle outlet initiates a shock wave at the rotor chamber nozzle outlet. A second, normally stronger, shock wave is initiated at the inlet of each rotor chamber as it is exposed to the hot gases flowing from the heating chamber. Each rotor chamber is designed so that before this second shock wave (which is set up by the hot gases entering a rotor chamber already filled with cool gas) reaches the end of its excursion toward the rotor chamber outlet, the shock wave encounters the constricted area, or nozzle, of the rotor chamber. As a result this second shock wave is reflected from the rotor chamber nozzle toward the inlet of the rotor chamber. As a result of this reflected shock wave, the final pressure of both the cool gases and the hot gases within the rotor chamber is very high and is substantially higher than the initial pressure of hot gases flowing from the heating chamber. The rotor housing is designed such that ideally as the reflected shock wave reaches the inlet of the rotor chamber, this inlet is sealed as a result of rotation of
