Title: Process for the production of 11-bromoundecanoic acid
IPC: C07C51/363
Filed: 1953-07-31
Abstract: A process for the preparation of 11-bromoundecanoic acid is characterized in that undecylenic acid is treated with hydrobromic acid in the presence of an organic peroxide and in the absence of free oxygen. An organic dehydrogenatable solvent may be present in the reaction mixture, e.g. "Tetralin" (Registered Trade Mark) or cyclohexane or toluene together with "Tetralin" or cyclohexane. In the example, 11-bromo-undecanoic acid is obtained by passing hydrobromic acid into a toluene solution of undecylenic acid in the absence of air and using benzoyl peroxide as catalyst. For comparison toluene solutions of undecylenic acid in toluene are treated with hydrobromic acid in the presence of a stream of air and in the presence of air and benzoyl peroxide when 10-bromoundecanoic acid is produced as a by-product.
Patent ES-213621-A1 (ES)
Title: Improvements in and relating to the production of omega-amino nonanoic acid
Filed: 1954-02-11
Abstract: o -Amino nonanoic acid is prepared by subjecting an unsaturated acid occurring naturally in vegetable oils and having the formula R-CH=CH(CH2)7COOH, R being an aliphatic monovalent radical, to oxidative cleavage to form azelaic semi-aldehyde OHC-(CH2)7COOH, together with a further aldehyde RCHO as byproduct, the oxidative cleavage being effected either by reacting the acid with hydrogen peroxide to form a corresponding dihydroxy substituted acid and oxidizing this acid to form the aldehydes or by reacting the acid with ozone to form an ozonide which is subjected to hydrolysis or catalytic hydrogenation to form the aldehydes, and then either reacting the azelaic semi-aldehyde with hydroxylamine to form azelaic semi-aldoxime and hydrogenating the aldoxime in the presence of a hydrogenation catalyst to the desired amino-nonanoic acid or hydrogenating the azelaic semi-aldehyde in the presence of ammonia and a hydrogenation catalyst to the same amino acid. In a modification of the process, esters of the aminononanoic acid are prepared following the same sequence of reactions and either starting with an ester of the original unsaturated acid or esterifying one of the intermediate products which contains an esterifiable carboxylic group, for example, the azelaic semi-aldehyde or dihydroxy acid. In examples: (1) oleic acid in dry ethanol is treated with ozonized oxygen and the resulting solution of ozonide is hydrogenated in presence of palladium on calcium carbonate as catalyst the aldehyde mixture formed is reacted with hydroxylamine hydrochloride in presence of excess sodium acetate and the solution refluxed after removal of solvent, pelargonic aldoxime is precipitated by excess of aqueous sodium carbonate and thereafter azelaic semi-aldoxime is precipitated on acidification the azelaic semi-aldoxime is hydrogenated in ethanolic solution in presence of ammonia and a Raney nickel catalyst and the ammonium salt of the desired amino-nonanoic acid recovered from the product and converted into the free amino-acid the aldehydic products of the oxidative cleavage may be separated before the oxime-formation step by distillation or the semi-carbazone method (2) oleic acid is hydroxylated with hydrogen peroxide and acetic acid, and the resulting 9 : 10-dihydroxy stearic acid recovered and converted to its ethyl ester the ester is oxidized in dry benzene with lead tetra-acetate and the so-obtained pelargonic aldehyde and the ethyl ester of azelaic semi-aldehyde recovered by distillation the ethyl ester is converted into its oxime which is hydrogenated as in (1) to yield ethyl 9-amino nonanoate (3) as in (2), the ethyl ester of the azelaic semi-aldehyde being hydrogenated in ethanolic solution in presence of ammonia and Raney nickel to form ethyl amino nonanoate. Reference is also made to linoleic and ricinoleic acids and their esters. According to the Provisional Specification, R is any monovalent radical.
Patent ES-289571-A1 (ES)
Title: Process of producing spheroids of nuclear fuel materials by agglomeration
IPC: G21C3/62
Filed: 1963-07-02
Abstract: Granules of fissile or fertile material or mixtures thereof are placed in a container to which a gyratory vibration is applied so as to form spheroids, and the formed spheroids are subsequently enlarged by addition of further quantities of said material. Initial addition of the further quantity is at a lower rate, e.g. 25 g. per 15 minutes until spheroids are enlarged to 400 microns, than subsequent addition, e.g. 25 g. per minute, so that the added material causes enlargement rather than fresh spheroid formation. The added material is preferably powder of particle size smaller than the granules. The gyratory vibration is interrupted at e.g. hourly intervals to permit removal of undersized spheroids by sieving, and these may be reground for further addition as powder. A mixture of 500 g. uranium dioxide, 67 g. carbon black and 0.25% aluminium stearate is ball-milled for 16 hours to form granules which are spheroidized in a polyethylene bowl secured to a sieve-shaker imparting reciprocating motion in a vertical plane and oscillatory angular motion in a horizontal plane. Addition of powder which may be that obtained from the ball milled material by passage through a 100 mesh sieve, or which may be unsieved ball-milled material, causes enlargement from 230 microns up to 1 mm. The spheroids are reaction-sintered in vacuo to remove carbon monoxide and the dense non-porous spheroids of uranium carbide formed may be coated with silicon carbide or pyrolytic carbon, dispersed in a matrix of silicon carbide or carbon and the matrix formed into a nuclear fuel body. The container may be smooth or its internal surface may be fine abrasive. Ball milled or granulated uranium dioxide may also be used as the starting material and the formed spheroids coated and dispersed in beryllia. The powder to be added is advantageously first subjected to the action of a fluid energy or jet mill.

Patent ES-314017-A1 (ES)
Title: Needled nonwoven pile fabrics and method of making same
IPC: D04H11/08
Filed: 1965-06-09
Abstract: A simulated pile fabric comprises a first layer of fibres forming a foundation layer and a second layer of fibres forming a fibre tuft precursor layer fibres from the second layer are oriented through the foundation layer and project beyond the surface thereof in the form of fibre tufts which are set in the foundation layer, at least a proportion of fibres in at least one layer being composite fibres having at least one potentially adhesive component which is activatable to effect the setting of the fibre tufts. The fibre tufts are preferably additionally set by the crimping of at least some of the fibres of the foundation layer. The fibres of the second layer are oriented through the foundation layer by passage of the layered structure through a needle loom, the crimp in the fibres then being developed by heat treatment. Preferably the fibre tufts projecting beyond the surface of the foundation layer are also crimped, Fig. 4 (not shown). The foundation layer and the second layer may each comprise a plurality of layers of fibres. When used as floor-covering material, the non-woven fabric may be attached to a hessian scrim with or without a polyurethane foam layer. Alternatively, the hessian scrim with or without the polyurethane foam may be situated between the foundation layer and the fibre tuft precursor layer. The fibres present are prefarably polyamide, but polypropylene, polyethylene, polyurethane and polyethyleneterephthalate are also mentioned. Prior to or during the spinning operation, pigments, plasticisers, dyes, moth- and fire-proofing agents, fillers and the like may be added. The potentially adhesive component of the fibres may be activated by heat or chemical media e.g. a non-aqueous formaldehyde solution.
Patent ES-322523-A1 (ES)
Title: Improvements in spot suppression circuits in a cathode-ray tube
IPC: H04N3/24
Filed: 1966-02-02
Abstract: The beam of a cathode-ray tube is suppressed during fly-back periods by the application to the control grid W (Fig. 5) of negative pulses derived in a circuit including a transistor T supplied with signals occurring in the line and frame scanning circuits BL, BT during flyback periods. Such signals are not of the ideal shape (rectangular) for correct suppression tending rather to approach a semi-sine curve and to be accompanied, particularly in the case of signals from the line scanning circuit, by parasitic (overshoot) pulses, the former resulting in only partial suppression during the fly-back and the latter resulting in unwanted blanking during the commencement of the trace period (Fig. 3, not shown). These defects are removed by adjustment of the ratio of the potential divider formed by resistors R 1 , R1 1 , and R 2 to make the amplitude of the parasitic pulses slightly lower than the cut-off voltage of the transistor so that the latter passes rapidly from cut-off to saturation on the occurrence of the true fly-back signal resulting in the production of rectangular suppression pulses of the correct width and substantially free from the parasitic pulses.

Patent ES-345013-A1 (ES)
Title: Method for controlling stepping motors
IPC: H02P8/26
Filed: 1967-09-13
Abstract: A stepping motor is decelerated with reduced oscillation and stopped in a desired position by interrupting a train of driving pulses before the position is reached, and then applying a clamping pulse when the rotor has moved at least one step beyond the point of interruption and starts to reverse. If the rotor moves beyond the point of interruption by more than 1 steps, clamping pulses are applied to the motor equal in number to the number of further steps and at a frequency equal to twice the natural frequency of damped oscillations of the rotor. The motor A is supplied through an electronic switch P controlled by a multivibrator comprising transistors 1, 2, the frequency of the pulses derived from the multivibrator being determined by the time-dependent voltage developed acros the emitter resistance 23 of transistor 24. A control circuit for the transistor 24 comprises switch S which is opened to render transistor 30 non-conductive whereby transistors 31, 38 conduct and diode 37 is blocked so that the multivibrator starts to oscillate. Capacitor 40 begins to charge and transistor 24 is driven to clamp the voltage applied to capacitors 3, 4, this voltage decreasing linearly with time to increase the frequency of the motor-driving pulses. When the switch S is closed, the multivibrator 1, 2 is cut-off and transistor 51 passes the last pulse to a monostable multivibrator OSA which, after a delay period, changes-over a flip-flop FF and drives multivibrator OSB into the astable state. Multivibrator 55, 56 now oscillates freely, with a delay equal to the time constant of the multivibrator OSA, and supplies a first clamping pulse to the switch P which differentiates the pulse for application to the motor. The voltage developed across the resistor 23 is transferred through diode 71 to the circuit OSA whose time constant is reduced as the motor speed increases. The multivibrator 55, 56 is adapted to produce a train of clamping pulses whose repetition rate is adjusted by oscillation of the rotor. When this train is interrupted, the multivibrator OSB drives the flip-flop FF back to its initial state in which it cuts-off the multivibrator 55, 56.
Patent ES-347197-A1 (ES)
Title: Electrical control device for a hydraulic circuit
IPC: F15B21/08
Filed: 1967-11-15
Abstract: A hydraulic motor comprises a double-acting piston 2, Fig. 1, controlled by an electromagneticallyactuated distributer 9 biased into a neutral position 9b by springs 14, 15. From the rest position shown of the motor, depression of a manual starting switch (Ma), Fig.2 (not shown), energizes electromagnet Aresultingin rightward movement of the distributer and consequent connection of the cylinder spaces 5 and 6 respectively to a pressurized fluid supply line 10 and a return line 11. Moreover, the moving distributer, via a lever 23, opens switch A 2 and closes switch A 1 which thereafter maintains the electromagnet A energized so that the manual starting switch (Ma) can be released. The eventual rightward movement of the piston 2 causes a cam 4 to close switch FCO, open switch FC 1 and then close switch FC 2 . Opening of switch FC 1 deenergizes electromagnet A and the springs 14, 15 return the distributer to its neutral position shown whereat the switch A 2 is closed, so that the electromagnet B is energized through closed switches FC 2 and A 2 . The distributer is then moved leftwards and reverses the supply and return connections to the cylinder and, via a lever 22, opens switch B 2 and closes switch B 1 . The closed switch B 1 together with closed switches FC o and A 2 maintain the electromagnet B energized since the switch FC 2 is opened shortly after commencement of the leftward movement of the piston 2. This movement continues until switch FCO is again opened to de-energize electromagnet B and allow the distributer to return to the neutral position. Thus the machine has completed one cycle after which its operation ceases unless a re-cycling switch (Ca) has been closed during the first cycle.
