Patent ES-296385-A1 (ES)
Title: Apparatus for the winding of roller-driven, cross-wound bobbins
IPC: B65H54/44
Filed: 1964-02-13
Abstract: The invention relates to yarn winding mechanisms in which a package 2, driven by a drum 1, is used to drive a yarn traversing mechanism 15. To reduce the torque that must be transmitted from the drum 1 to the package 2 to drive the traversing mechanism 15, an auxiliary member 21 is provided that supplements the drive to the traversing mechanism 15 via a ribbon or cord like member 13 providing a frictional one way driving effort from the auxiliary member 21. In Fig. 1 the package 2 drives a pulley 9 via a system of belts 6, 8. The pulley 9 and the traversing drum 15, are freely mounted on a spindle 11 but are interconnected by a cord 13 wrapped several times around the spindle 11. An auxiliary variable speed motor 21 drives the spindle 11 in the same direction as the pulley 9 and thus provides a frictional drive that lessens the resistive torque of the package 2 being driven by the drum 1, the speed of the motor 21 varying with the displacement of the bobbin axis as the package grows. In Fig. 3 (not shown) the package 24 drives a shaft 25 on which are freely mounted two belt pulleys 26, 33. A cord 31 is wrapped around a hub of the belt pulley 33, one end of the cord being connected to a clamp 32 on the belt pulley 26 and the other end being connected to a bracket 30 attached to the shaft 25 and extending through a slot in the belt pulley 26. The auxiliary motor 39 drives the belt pulley 33 in the same direction as the package 24, but at a faster speed, and this causes the belt pulley 33 to transmit a frictional drive via the cord 31 to the shaft 25 to reduce the resistance to motion of the package 24.

Title: Demodulating circuit for waves frequency modulated by signals of the video type
IPC: H04N11/18
Filed: 1967-03-03
Abstract: To ensure correct D.C. restoration of a wave frequency modulated by a video signal an auxiliary circuit is provided which substitutes for the frequency modulated wave during a portion of each blanking interval of the video signal a constant frequency signal which after demodulation in a frequency demodulator becomes a constant value signal suitable for clamping by a conventional clamper. In the embodiment described a SECAM (Trade Mark) subcarrier which is frequency modulated by chrominance signals A 1 and A 2 alternately at line frequency having resting frequencies F 0 and F1 0 respectively is received at input 1 of a switch 3, Fig. 1, and a constant amplitude signal having frequency F 0 during line periods corresponding to the transmission of signal A 1 and frequency F1 0 during the line periods corresponding to the transmission of signal A 2 is received from a generator 102 at input 2 of switch 3. The state of switch 3 is controlled by a generator 103 so that the signal from generator 102 is transmitted to a frequency demodulator 4 (centered for example on frequency (F 0 + F1 0 )/2) during a portion E of each blanking period J, Fig. 2. The signal at the output of demodulator 4 has the shape represented in Fig. 2. The output of switch 3 may be fed to a conventional SECAM decoding circuit comprising a direct channel, a delay channel, a switch and two demodulators.

Abstract: Diazonium compounds of formula wherein R 1 , and R 2 are unsubstituted or substituted alkyl, aralkyl or cycloalkyl, or together form an unsubstituted or substituted heterocyclic ring, R 3 is hydrogen, alkoxy or fluorinated alkoxy, R 4 and R 5 are hydrogen, halogen, alkyl, alkoxy or fluorinated alkoxy and X is an anion at least one of R 4 and R 5 being hydrogen and at least one of R 3 , R 4 and R 5 being a flurinated alkoxy radical may be prepared by one of the following methods. (1) 1-chloro-2-nitro-alkoxybenzene is reacted under alkaline conditions with a fluorinated alcohol to give the nitro-hydroquinone-diether. The diether is reduced, diazotized and then by the Sandmeyer reaction produces the chloro-hydroquinone-diether. This diether is nitrated in the para position to the chlorine then reacted with a secondary amine or a heterocyclic base and the product is reduced and diazotized (ii) 2,5-dichloro-nitrobenzene is reacted under alkaline conditions with a fluorinated alcohol to give the 4-chloro-2-nitrofluoroalkyl ether which is reduced and the resulting amine is alkylated or aralkylated. This compound is nitrated to produce the 4-chloro-5- nitro-2-dialkylamino-phenyl-fluoroalkyl ether which is reduced and diazotized to give the diazonium compound, (iii) 3-chloro-4-nitroaniline is reacted with a fluorinated alcohol under alkaline conditions to yield the 2-nitro-5- amino-phenyl-fluoroalkyl ether. The amino group is now alkylated or aralkylated and the nitro group is reduced and diazotized to yield the diazonium compound. Specific diazonium compounds referred to are those prepared from 1 -amino-4-pyrrolidino- -4-morpholino- and -4- piperidino - 2 - methoxy - 5 - (21,21,21 - trifluoro ethoxy) - benzene 1 - amino - 4 - morpholino - 2,5 - diethoxybenzene and 1-amino-4-dimethylamino - 2 - chloro - 3 - (2,2,2-trifluoroethoxy) benzene and are in the forms of zinc chloride double salts or tetrafluoroborate.
Patent ES-357568-A1 (ES)
Title: Fluid cushion skirt arrangements for ground-effect machines
IPC: B60V3/04
Filed: 1968-08-26
Abstract: A tracked air cushion vehicle has a cushion containing skirt system whose position relative to the supporting track surface is determined by a spring and damping system. A flexible skirt member 2 is attached by bolts 9 to a U-shaped member 8 which is pivotally attached by brackets 10 to an extension 7 of the vehicle body at 4. Also attached to the U-shaped member 8 are two flexible diaphragms 11 and 13, which enclose an airspace 5 which communicates with the main air cushion 1 through holes 12. A second skirt member 14, which is normally further from the track surface than is the skirt member 2, is attached to the vehicle body 3, as are diaphragms 11 and 13. Clamped at 16 to the vehicle body extension 7 are torsion bars 15 which pass through bearings 17, the bearings having sufficient friction to damp motion of the torsion bars. When an obstacle is encountered by the vehicle so that skirt member 2 is lifted away from the track surface, the torque exerted by the torsion bars on the member 8 increases this increase in torque may be matched by the increases in torque of the air pressure forces acting on diaphragm 13 so that overall cushion stiffness is maintained, Fig. 2 (not shown). If these torque increases are not matched, the decreased clearance between track and skirt member 14 may be used to stiffen the innermost portions of the air cushion. Damping of vibrations of the skirt occurs due to the torsion bars and their bearings, and because pressure variations in the air space 5 are out of phase with those in the cushion 1. The torsion bars may be supplemented by hydraulic rams, Fig. 3 (not shown), and additional damping may be derived from a matched resonator attached to the U-shaped member 8, Fig. 4 (not shown). The invention may be used without the diaphragm 11.

Title: Apparatus and method for mixing and pumping fluid explosive compositions
IPC: B01F13/10
Filed: 1969-05-30
Abstract: An explosive slurry comprising a solution of an oxidiser and suspended solid particles is prepared by feeding solid particles and liquid at controlled speeds to a mixer, withdrawing slurry from the mixer, pumping it to a delivery point, e.g. a borehole, and recycling part of the slurry through the slurry pump in order to control the density and other physical properties of the slurry. The liquid fed to the mixer may be a heated aqueous solution of ammonium nitrate and sodium nitrate containing guar gum as a delayed action thickener. The finely divided solid materials may be, for example, further oxidiser and aluminium powder and other fuels or sensitisers. Apparatus is described, Figures 1-8 (not shown) in which a petrol motor 25 drives, through a single main drive, a pump 119 for the aqueous solution, augers 169, 180 for feeding the solid materials at separately controllable rates, the stirrer in mixer 99, and slurry pump 93. The mixer and the slurry pump are interconnected so that they always work together. The composition of the explosive and the degree of aeration may be varied during pumping into a borehole. An air compressor is also provided to operate pneumatic controls and to pressurise a water tank for auxiliary liquid supply and cleaning. The apparatus may be mounted on a vehicle or may be removed and used in a mine tunnel. In an alternative arrangement, Figure 9 (not shown), the drive means and control are fluid operated by a master pump system.
