Patent ES-337356-A1 (ES)
Title: Water extractive distillation of an ethylene oxide stream containing formaldehyde
IPC: C07C67/00
Filed: 1967-02-28
Abstract: Ethylene oxide is separated from an aqueous solution of ethylene oxide and formaldehyde by distillation to obtain ethylene oxide as an overhead vapour the amount of formaldehyde in this vapour being reduced by introducing water as sole extractive agent to the distillation and purging the bottoms from the distillation to remove formaldehyde from the system. The aqueous starting solution may be obtained by scrubbing with water, the gaseous ethylene oxide and formaldehyde containing mixture produced by the partial oxidation of ethylene in the vapour phase. The extractive distillation may be carried out in two columns with the aqueous feed solution being fed to the upper portion of the first column and the extractive water being fed to the upper portion of the second column, overhead vapour from the first column being fed to the lower portion of the second column and liquid bottoms from the second column being fed to the upper portion of the first column.

Abstract: A metal shipping container, Fig. I (not shown), is formed in two parts 1, 2 the open ends of which are joined by means of an organic adhesive 18, of a type which melts or disintegrates when heat or a solvent is applied, so that the container may be disassembled for cleaning. Alternatively, the adhesive 18 may be used to secure end walls of the container to its side wall. One of the interfitting portions 7, 8 may be folded back on itself, thereby sealing the adhesive layer 18 from the container contents Fig. 6 (not shown) or the portions 7, 8 may both be either outwardly flared, Fig. 7 (not shown), or inwardly tapered, Fig. 8 (not shown), without overlapping, the join being effected by means of a biconical ring inside or outside the container side wall respectively. The ends (3, 6), which may be welded, are as shown in Fig. 4. The adhesive may be applied in powder form to the areas to be joined which are pre-coated and heated.
Patent ES-343991-A1 (ES)
Title: Synthesis of iron enneacarbonyl
IPC: C01G49/16
Filed: 1967-08-10
Abstract: Iron enneacarbonyl, Fe 2 (CO) 9 , is prepared in a continuous process by irradiation of pure Fe(CO) 5 at a temperature less than 20 C. with light of wavelength exceeding 400 mÁ and having its intensity predominantly in the wavelength range 400-700 mÁ. The Fe(CO) 5 is purified by distillation and preferably used immediately to minimize decomposition to Fe 3 (CO) 12 , whose presence causes reduced yields of product. The light used has a wavelength greater than 400 mÁ, to avoid rapid deposition of product on the walls of the reaction vessel halting the reaction, and less than 700 mÁ, to reduce the optical path length necessary for total absorption of light. The product Fe 2 (CO) 9 dissolves in Fe(CO) 5 to give a yellow solution which absorbs light in the wavelength region 400-600 mÁ, thus reducing the rate of reaction. This is avoided by keeping the temperature below 20 C., and also by making a 1-95% solution of the initial Fe(CO) 5 in a chemically and photo-chemically inert solvent, to minimize the solubility of the Fe 2 (CO) 9 , and thus to facilitate its removal by filtration.

Title: Fruit press
IPC: B30B9/24
Filed: 1967-09-13
Abstract: In a fruit press of the travelling band type in which the fruit is pressed between a pair of permeable webs 14, 15 threaded in serpentine fashion over a plurality of rollers, said rollers are mounted on the supporting frame at one end only in cantilever fashion. Fruit is fed on to band 14 by means of a tube 17 parallel to the rollers and containing a screw conveyer 18, a spreader plate 19 aiding in distribution. Pressed pulp is removed from web 15 by means of a scraper plate 20. Juice is collected in shrouds 62 with delivery conduits 63. Rollers 11 and 12 are mounted on pivoted arms adjustable by threaded means, e.g. 58, for controlling belt tension and roller 16 is similarly mounted for adjusting the throat opening of the press. Fig. 4 shows the cantilever mounting of a single roller 1 comprising an axle 37 bolted thereto and passing through a boss 32 on the machine frame, bearings 40 and 41 being thus able to be situated a sufficient distance apart to provide cantilever support. A hydraulic motor 44 is fitted to certain of the rollers. The frame of the machine consists of a number of separate castings, e.g. 21-27 and 29 bolted together so that it may be assembled in different ways with varying numbers of rollers. In a particular embodiment having 2 pressing stages (Fig. 9, not shown) only rollers 1, 2, 3, 10, 13 and 16 are present, belt 15 is omitted and belt 60 co-operates with a shortened belt (141) passing directly from roller 3 to roller 10, pressed fruit pulp being discharged at the periphery of roller 3.

Title: Improvements in or relating to Apparatus for Providing D.C. Pulses of Predetermined Duration
IPC: H03K3/57
Filed: 1967-12-07
Abstract: A pulse generator comprises a thyratron or thyristor 3 connected as shown to terminals of a load 4 and direct current supply 1, 2. As described, capacitor 5 is initially charged with the polarity shown via the load 4 and the path E-B 1 of unijunction transistor 7. When the unijunction transistor 7 becomes non-conductive, capacitor 5 discharges slowly via 4 and 6 until unijunction transistor 7 is again triggered, recharging the capacitor with the polarity shown. The duration of the charging pulses is sufficiently short as to have no effect on load 4. When the thyratron or thyristor 3 is fired by a short pulse applied to its control electrode, the load is connected across the direct current supply, initiating an output pulse. Capacitor 5 is immediately discharged via devices 3 and 9 and subsequently recharged through resistor 6 until unijunction transistor 7 once more becomes triggered when capacitor 5 discharges via the thyristor 3 and path E-B 1 , quenching the thyristor 3 and terminating the output pulse in load 4. The duration of output pulse may be adjusted by variation of resistor 6.
Patent ES-352587-A1 (ES)
Title: Resilient support
IPC: F16F3/00
Filed: 1968-04-09
Abstract: A spring unit consists of an elongate tension element (such as a wire or rod 1, Fig. 1, or a tube 43, Fig. 13) in combination with a series of compressible elements which are placed in compression when the tension element is tensioned, means being provided to vary this tension. One of the series of compression members constitutes a buffer element (e.g. 31 in Fig. 4, 34 in Fig. 11) which becomes effective only at a predetermined tension. The unit functions as a transversely bendable spring of adjustable stiffness. The compression elements additional to the buffer may be discrete metal or plastics bodies 2, Figs. 1 and 4, or 45, Fig. 13, or 2a, 2b, 2c, Fig.17, or alternatively adjacent portions of an integral strip 39, Figs. 11 and 12, leaving partly stamped out and turned over tongues 42 through which the tension element passes. The buffers may be of metal (e.g. coil springs or series of dished discs as at 34 in Fig. 11) or of rubber. Fluid and electromagnetic buffers are also mentioned, but not disclosed in detail. The tension adjusting means may be a pantograph mechanism 9-12, Fig. 1, or cam 24, Fig. 4. It may be operated mechanically, hydraulically or electromagnetically. There may be more than one tension element as at la, 1b 1c, Fig. 17, or as in Figs. 6, 16 and 18 (not shown). Figs. 19 to 23 (not shown) depict alternative constructions in which the compressible elements are threaded on a rod or wire type tension element and also located within a flexible tube. In these constructions the compressible elements are: blocks (56, Fig. 19) generally similar to the elements 2 of Fig. 1 but of taper - ing form balls (Figs. 20 and 21) or the turns of a helical spring of either constant (Fig. 23) or varying (Fig. 22) diameter. Reference has been directed by the Comptroller to Specification 1,110,414.

Patent ES-361850-A1 (ES)
Title: Production of carbon black
IPC: C09C1/50
Filed: 1968-12-26
Abstract: Carbon black is produced by contacting a hydrocarbon feedstock in a first reaction zone with hot free oxygen containing gas, feeding the reaction mixture into a second zone and therein contacting the mixture with hot combustion gas produced by combustion of a fuel in the presence of an amount of oxidant less than that required for complete combustion of the fuel. The free oxygen containing gas used in the first zone is or comprises air and has a free oxygen content of from 125-190% of the theoretical amount required for complete combustion of the fuel the combustion gas used in the second zone has an oxygen content of from 50-85% of the theoretical amount for complete combustion.
Patent ES-368667-A1 (ES)
Title: Method and apparatus for the purification of heavy water
IPC: B01D59/32
Filed: 1969-06-21
Abstract: The hydrogen and tritium content of heavy water is reduced by diverting a continuous flow of heavy water from a reactor to an isotopic exchange reaction with deuterium, passing the contaminated deuterium to a chromatographic fractionation whereby hydrogen and tritium are separated leaving pure deuterium which is recycled to the isotopic exchange reaction. Solid catalysts such as Pt or Pd on inert supports, iron oxide or Ni deposited on chromium oxide can be used to initiate the exchange reaction or alternatively thermal activation may be used, the exchange temperature being preferably 80-400 C. in the former case and 800-1200 C. in the latter. The fractionation may be performed in a moving solid or static solid column. In the former embodiment the impure D 2 enters the column at an intermediate point tritium rich D 2 leaving the top of the column and hydrogen rich D 2 leaving the bottom of the column. The solid absorbent is heated as it leaves the bottom of the column, freeing the absorbed gases which then pass up the column, the solid being recycled to the top of the column. Alternatively (see Fig. 3) the impure D 2 enters column 17 at 23. Tritium rich D 2 leaves via 24. The hydrogen rich D 2 passes via 25 to a second column 18 from which pure D 2 leaves via 27, hydrogen rich D 2 being removed at 26. This arrangement may be reversed, i.e. hydrogen rich D 2 may be separated in a first stage. The separating solid is preferably palladium based. The hydrogen rich D 2 may, by methods known per se, be subjected to isotopic enrichment to recover part of the heavy water. The tritium rich D 2 may similarly be treated to recover the tritium.
Patent ES-368965-A1 (ES)
Title: Printed circuit board liners and insertion method and apparatus
IPC: H05K3/34
Filed: 1969-06-30
Abstract: A terminal element for use in circular holes 26 of a printed circuit board 20, e.g. of epoxy resin, (not shown) comprises a tubular sheet-metal member having an arcuate end 6, and an oval end 4 having its major axis greater than twice the radius of arcuate end 6, the terminal element optionally including an open seam 8 and a finger-like retaining member 10 with an 'ear' formation 16. Each terminal when assembled in a hole in a printed circuit board is resiliently retained therein and is engaged by an external lead wire which is electrically connected to the terminal by, e.g. dip soldering. Insertion of the lead wire in the terminal opens out the formation 16 to abut an edge of the hole thereby preventing the terminal from moving in one direction during handling before soldering. A method of assembling such elements in the holes of a printed circuit board consists in using a template 22 (Fig. 5) having holes 28 corresponding to those in the printed circuit board, each hole 28 being filled with a terminal element from a plurality of them placed on the template, the entry of the terminals being effected by vibratory means. Terminals so lodged are transferred into holes 26 of the board 20 by the action of punching members 32 which are fixed underneath a plate 24 mounted in a machine (Figs. 13 and 17, not shown) which also includes other plates, guide posts extending into bushing supports through ball bearing retainers, aligning pins and components to hold warped printed circuit boards straight while the terminal elements are inserted through the template holes into the printed circuit board holes.

Patent ES-434253-A1 (ES)
Title: Container that can be displaced by rotary force
IPC: B60P3/30
Filed: 1975-01-29
Abstract: The present invention relates to a new container that can be displaced by rotary force, consisting of a continuous sheet that assumes a form similar to a cylindrical surface, generated by a rectangle whose shorter sides have been substituted by convex semicircumferences, when it rotates around an axis that is very close and parallel to one of the long sides. An element is then placed in the direction of the axis and forms the axis of rotation. This element is held fast by the container when the latter is filled with fluid or other matter that induces multidirectional pressures of sufficient magnitude to cause the element installed, when impelled by a force, preferably along the axis but from either direction, to pull with it the enclosed sheet, thus displacing the container by rotary force over the supporting surface.

Title: Method and device for cutting rove at doffing in flyer frame
IPC: D01H9/16
Filed: 1976-03-04
Abstract: A method and device are disclosed for cutting a rove at doffing in a flyer frame, wherein during the normal winding operation thereof the rove drawn out from front rollers is passed through the center hole of a flyer top, the hole of a hollow leg of a flyer, and over a presser and wound on a driven bobbin which is arranged on a bobbin rail moving up and down along the bobbin guide arbor of the flyer. Just before the doffing, the supply of the rove from the front rollers is failed and the bobbin and the flyer are caused to continue rotations substantially at the same speed for a time period sufficient to allow a predetermined number of rotations of both the bobbin and flyer, whereby the rove between the flyer top and the front rollers is subject to a stronger twist than that given during the normal winding operation. This assures that the rove is always cut of itself at an optimum portion thereof at the doffing.
