Patent ES-343984-A1 (ES)
Title: Process for the treatment of Filaments and like Structures of Linear Polyesters
IPC: D01F6/62
Filed: 1967-08-10
Abstract: The rate at which polyester filaments and like structures can be drawn without minute cavities or "bubbles" forming in the filaments during the drawing step is increased by subjecting the filaments prior to the drawing step to a heat treatment step which is carried out at a temperature T ( C) and during a time t (sec.) such that T = A-X.(log e t) in which, with a duration of heat treatment of 0.3 to 3 seconds, A has any value in the range 77.7 to 95.7 and X = 7.6, and when t = 3 to 3600 seconds, A has any value in the range 72 to 90 and X = 2.48 and, when t = 3600 to 200,000 seconds A has any value in the range 54.6 to 72.6 and X = 0.354. The drawing step may be effected under such conditions that the filaments are thereby oriented and may be effected at ordinary or at elevated temperatures. When the drawing step is carried out at elevated temperatures, it is immaterial whether the filaments are cooled between the heat treatment and the drawing steps or whether they are heated to the temperature required for drawing directly after the heat treatment step. Any method of heating the filaments may be used in the heat treatment step and the filaments may either be prevented from shrinking or may be allowed to shrink to a controlled degree (preferably not more than about 10%) during this step. The filaments may consist of polyethylene terephthalate. The heat treatment of the undrawn filaments &c. can be carried out in a hot liquid, preferably water, in a heated gas or vapour, by radiated heat, dielectric preheating, or by contact with one or more heated surfaces. The heat treatment increases the speed at which the filaments may be drawn without minute cavities forming in them. The polyester used in all the examples is polyethylene terephthalate.

Patent ES-347127-A1 (ES)
Title: Manufacture of a fancy yarn
Inventor: SEGUIN PIERRE
IPC: D01H5/36
Filed: 1967-11-14
Abstract: A helical, fancy yarn of a polyamide, polyester or polyacrylonitrile is continuously produced by winding yarn onto a stationary needle, advancing the coiled yarn along and off the needle and through a heater wherein the coils are heat-set and then cooling the yarn in an accumulator - both the heating and cooling occurring when yarn is relaxed. In the apparatus shown, a yarn 28 fed into the passage 1a of a hollow rotating shaft 1 emerges through one of the ports 2a or 2b, follows longitudinally the surface of a rotating member 2 and is wound spirally on a tapered needle 7 which is magnetically restrained by the magnetic attraction between a pole piece 6 (carried on small shaft 3) and poles (8, 8') of a stationary magnet or magnets. The yarn turns, under the influence of a spring-loaded driven roller 12, are continuously displaced towards the free end of the needle. Coiled yarn passes through tube 10 into a steam heater 11 wherein the yarn deformation is set. On emerging from the heater, yarn passes through tubes 20, 21, into a channel in an element 22 pivoted on a knifeedge 23 and counterbalanced by a weight 24. The coiled yarn accumulates until its weight rocks the element 22 so that a pointed member 26 contacts a mercury bath 27 to close an electric circuit and thereby initiate operation of yarn withdrawal or winding mechanism: when the weight of yarn in the channel has decreased sufficiently, the element 22 rocks (towards an adjustable limit stop 25) to open the circuit.

Title: Axial-mechanism control rod actuator
IPC: G21C7/12
Filed: 1967-12-13
Abstract: In a control rod actuator for a nuclear reactor comprising a leak-tight containment vessel which is sealed by a top plug, a rod 1 is disposed inside a stationary liner tube 2 within the seal plug 3 of the reactor and coupled at its upper end to a servomechanism 4 by means of which it may be raised and lowered within the tube 2. The lower end of the rod 1 is fitted with an electromagnet 5 for attaching an assembly 6 which is capable of sliding within a guide tube 7 and a rod 8 which is capable of sliding within the assembly 6. A grappler 9 which engages a control rod 10 is mounted at the bottom of the rod 8. When the control rod 10 is in its lowermost position (as shown in Fig. 1b) the electromagnet 5 is located at the level of the underface of the seal plug 3. The sliding assembly 6 comprises a tube slidable within the liner tube 2 and a spring 11 which is applied against a stopcollar 13 of the rod 8. The guide tube 7 is fixed to a horizontal arm 15 secured to a tube 16 which is located within the seal plug 3 and can be rotated by means of a servomechanism 17. A locking pin 19 also actuated by the servomechanism 17 through the intermediary of a rod 20 within the tube 16 serves to lock the sliding assembly 6 to the guide tube 7 in the bottom position when the electromagnet 5 is not energized. A bellows seal 21 concentric with the rod 1 is fixed at one end to the rod on an annular abutment flange 22 and at the other end to the liner tube 2 on an annular abutment flange 23. A spring 24 concentric with the rod 1 and applied against the flange 22 imparts to the sliding assembly 6 through the intermediary of a movable portion 25, on de-energization of the electromagnet 5, the impulse which is necessary for the rapid dropping of the control rod 10. Opening of the grappler 9 is obtained in the bottom position by de-energizing the electromagnet 5 after having locked the sliding assembly 6 to the tube 7. The rod 8 is then thrust downwards under the action of the spring 11 and the grappler arms separate since they are no longer held by the wall of the tube 6. In order to free the space necessary for the transfer of fuel elements when the sliding assembly 6 has been locked to the tube 7 and the electromagnet 5 de-energized, the arm 15 is rotated through 180 degrees.

Patent ES-372153-A1 (ES)
Title: Manufacture of drawn thermoplastic fibrillary products
IPC: D02J1/22
Filed: 1969-10-03
Abstract: A process for the drawing of a thermoplastic thread-shaped or ribbon-shaped product in a drawing zone between the point of arrival of the product on a feed roll and a draw roll which is driven at a circumferential speed that is higher than that of the feed roll, which process comprises the steps of feeding the product to the drawing zone, subjecting it to a first draw between the feed roll and at least one friction member in slipping contact with the product, localizing the drawing point as hereinbefore defined in the zone between the feed roll and the friction member, subjecting the thread to a second draw between the friction member and the draw roll, and discharging the drawn product from the drawing zone. In particular the process comprises feeding the thread to a driven feed roll 2, subjecting the thread to a first draw, feeding the thread to at least one friction member 4 over which the fibre slips, subjecting the thread to a second draw by feeding the thread to a draw roll 6 which is driven at a circumferential speed higher than that of the feed roll. The process may be used for linear polyester especially polyethylene terephthalate and linear polyamides especially nylon 6. The first draw may begin on the feed roll. The drawing point which is the point of maximum decrease in denier or drawing may be localized by continuously adjusting the temperature of a heatable zone, such as a feed roll, immediately prior to the drawing point. The friction member may be rotary or stationary through which liquid may be passed for controlling its temperature. The process may be used for spin drawing especially of polyethylene terephthalate when the driven friction member is heated to a higher temperature than the heated feed roll, the temperatures preferably being in the ranges 180 to 225 C. and 65 to 90 C. respectively. The frictional member and the feed roll may have matt chromium plated surfaces. In Fig. 3 for spin drawing nylon 6 the fibres are subjected to a relaxation process after the stretching by passing the fibres over rolls 12 and 13 which have a slower peripheral speed than the draw roll 6.

Title: Paint spraying method and apparatus
IPC: B05B5/035
Filed: 1970-12-23
Abstract: A method and apparatus for spraying paint and similar coatings. In one form the paint is sprayed at low pressure from a flat fan nozzle. A flat fan of air impinges upon the fan of paint at an angle of from 30 DEG -70 DEG . The air atomizes the paint to form a soft spray with low-forward velocity. In another form of the method, two fans of paint are projected toward one another at an angle and an air fan is directed along the bisector toward the zone of intersection. The air fan atomizes both streams of paint. An electrode can be placed in the air stream to ionize the air stream which in turn charges the paint particles. The width of the paint spray pattern is varied by varying the included angle of the air fan.

Title: Method of assembling a glow discharge readout device
IPC: H01J17/49
Filed: 1973-10-18
Abstract: In a glow discharge readout, cathodes are arranged on a glass substrate in electrical isolation from a plurality of anodes also on the substrate. Contact pins sealably imbedded in the substrate contact respective anodes and cathodes. A transparent cover forms a sealed envelope encasing the anodes and cathodes within an illuminating gas atmosphere. The anodes are purposely recessed with respect to the cathodes, whereupon an electrical potential impressed between the anodes and selected cathodes will cause electrons to flow from the cathodes to the anodes, the electron stream being focused toward the surface of the glass substrate and away from the transparent envelope thereby preventing electron collision with the transparent envelope. According to the method of the present invention, cathodes are formed from particulate metal particles sintered under pressure and at a temperature below the melting point of the metal particles, but at a temperature sufficient to cause fusion of the substrate material. Upon fusion of the substrate in an inert atmosphere, the anodes, cathodes and contact pins are fused to the substrate simultaneously in a single operation. Applying molding pressure during fusion of the substrate will desirably recess the anodes from the cathodes.

Abstract: A security closure device for a bottle, which is intended to prevent the fraudulant refilling of a bottle is disclosed. The bottle closure device disclosed has an internal valve which is held shut when the device is in a normal upright position by the weight of a ball which is trapped in a valve chamber between the valve shutter and a plurality of inclined radial ribs. The inclination of the radial ribs is such that when the bottle closure device is held with its axis horizontal the ball rolls down those of the ribs which are lowermost at the time and into engagement with the valve shutter to hold this shut against the valve seat. In order to open the valve it is necessary to tilt the bottle closure device to a position past the horizontal where the ball can roll along the edges of those of the radial ribs which are lowermost at the time to release the valve shutter and allow liquid to flow from the bottle.
Patent ES-452453-A1 (ES)
Title: Stubless multi-ply assembly
IPC: B41L1/24
Filed: 1976-10-16
Abstract: A unit set or assembly of multiple plies includes superimposed top, intermediate and bottom plies as well as a cover ply disposed over the top ply. A flap is removably connected to this cover ply along the line of weakening and underlies the bottom ply. First and second axially aligned holes of different sizes are respectively provided in the bottom and intermediate plies, the size of the bottom ply holes being less than the size of the intermediate ply holes. Adhesive is provided on the flap for securing the top ply thereto, such adhesive extending through the intermediate ply holes. The size difference between the axially aligned holes defines portions of the bottom ply which serve to mask the intermediate ply holes so as to confine the cross-sectional size of the adhesive, which extends therethrough, to the smaller size of the bottom ply holes. Accordingly, the cover ply may be removed from the set while leaving the remaining plies intact, and separation of the top and bottom plies breaks the adhesive and frees the intermediate ply. Thus, a multi-ply set is provided without the need for a removable stub thereby resulting in paper savings and avoiding the need for stub handling and disposal.

Title: Color improvement of high pressure sodium vapor lamps by pulsed operation
IPC: H01J61/22
Filed: 1977-01-15
Abstract: High pressure sodium vapor lamps containing sodium or both sodium and mercury are raised in color temperature and improved in color rendition by pulse operation. During the pulse there is considerable enhancement and broadening of the sodium lines at 449, 467, 498 and 568 nm and the development of a continuum from 400 to 450 nms, and also the appearance of visible mercury lines in lamps containing mercury. Optimum results with lamps in size ratings from 50 to 1000 watts are obtained with pulse repetition rates from 500 to 2000 Hz and duty cycles from 10 to 35%. The color temperature may be increased from the common value of 2050 DEG K to 2500 DEG K with reduction in lamp efficacy of only about 20% from conventional 60 Hz operation. Even higher color temperatures may be obtained if further reduction of efficacy is acceptable.
