Patent ES-221657-A1 (ES)
Title: Improvements relating to the preservation of fruit and other products
IPC: A23B7/154
Filed: 1955-05-07
Abstract: Fruits, particularly oranges, grapefruits, tangerines and lemons, and other agricultural products are treated with a phenolic mould-growth inhibitor which ordinarily tends to burn the surface of the agricultural product together with sufficient of a non-ionic suface-active agent to reduce this tendency. The phenolic substances are exemplified by phenylphenols, e.g. ophenylphenol and its sodium salt, and mono-chlorinated or mono-brominated phenylphenols. The non-ionic surface active agent may be a condensation product of an alkylene oxide with an organic compound containing a large non-polar group and an active hydrogen atom, e.g. a wool grease fatty alcohol or acid, or may be a compound having a large non-polar group, e.g. a long chain alkyl group, and an amino, amido or mercapto group. The agricultural product may be dipped in an aqueous solution or dispersion of the mould-growth inhibitor and surface-active agent, and the solution or dispersion allowed to dry. Aqueous preparations suitable for the treatment contain 0.25-1 per cent of the mould-growth inhibitor and 0.125-0.75 per cent of the surface-active agent. An ionic surface-active agent, e.g. a long chain secalkyl sulphate or a higher alkyl benzenesulphonate, may be used to assist dispersion in water of an only slightly soluble non-ionic surface-active agent. In the aqueous preparation may also be dispersed a substance such as paraffin wax, carnauba wax, beeswax or plasticized polystyrene which serves, after the drying of the preparation, to diminish evaporation of moisture from the product. Wrappers or packing materials for the agricultural products may be impregnated with a preparation of the mould-growth inhibitor and the non-ionic surface-active agent.

Title: Process for the production of new glycols
IPC: C07C31/18
Filed: 1959-07-03
Abstract: The invention comprises glycols of the general formula <FORM:0908504/IV (b)/1> in which R1 represents an alkyl radical having not more than 6 carbon atoms or a cycloalkyl radical having from 3 to 8 carbon atoms, R2 and R3 represent alkyl radicals having not more than 4 carbon atoms, or R1 and R2 together may form an alkylene radical, and R4 represents an unsaturated aliphatic hydrocarbon radical having 2 or 3 carbon atoms. They may be prepared by reacting, preferably in an organic solvent, an a -hydroxy ketone of general formula <FORM:0908504/IV (b)/2> with an organometallic compound prepared from magnesium or zinc and a compound of formula Hal-CH2-R4, in which Hal represents chlorine, bromine, or iodine, followed by hydrolysis. If desired, compounds in which R4 contains a triple bond may be catalytically hydrogenated to reduce the triple bond to a double bond. The a -hydroxy ketones used as starting materials may be obtained from ketones of formula R1COR2 by converting them to the corresponding cyanohydrins, blocking the hydroxy group, e.g. by acylation, reacting the products with alkyl magnesium halides of formula R3MgHal and hydrolysing the products. Alternatively when R2 and R3 are both methyl groups the starting hydroxy ketones may be obtained by condensing ketones of formula R1COCH3 with alkali metal acetylides and adding water to the ethinyl methyl carbinols so obtained.

Filed: 1967-11-07
Abstract: A current limiting circuit breaker having an arc-chute such as that described in Specification 1,196,798 is provided with a muffle 40 for the arc gasses, the muffle comprising first a set 51 of parallel, closely spaced plates 58A lying parallel to the direction of flow to cool the gasses and having parts 58B1 at an angle to the plates 58B to create turbulence and prevent reflected pressure waves occurring and secondly a set 53 of parallel closely spaced plates 60 lying across the direction of flow and provided each with a plurality of small holes, holes in adjacent plates being out of alignment. In the circuit breaker (Figs. 1, 2, not shown) the arc is driven against a wall 39 having slots 39A through which the gases escape, but the arc cannot move. The muffle is longitudinally divided by insulating barriers 49A-49C so increasing the arc path that restriking within the muffle is impossible. Adjacent plates 60 are separated by narrow spacers 62 and second, smaller set 55 of plates 60 is spaced from the first by a large spacer 54 the spacers 62, 54 are divided by cross members so as to reduce the spaces between the plates to filter out the appropriate frequencies of the sound waves. The assemblies of plates, &c. are placed, in abutment, inside a pair of insulating wrappers 67, 68 and then slid into a metal casing 42 where they are retained by bolts insulated by tubes 70. The casing 42 is provided in its remote end with openings, aligned with the openings in spacer 54, for the cooled gasses to escape. The spacers 62 may be of metal or vulcanized fibre and spacer 54 and wall 39 of glass fibre reinforced melamine.

Patent ES-349429-A1 (ES)
Title: Purine compounds
IPC: C07D473/32
Filed: 1968-01-17
Abstract: The Specification describes colour television signal mixing and/or fading circuit arrangements, for fading out one colour television signal and fading in another, said two signals being frame and line synchronized but the chrominance carrier F for each signal being differently modulated in alternation line by line (e.g. PAL or SECAM), and said alternations not necessarily being synchronous. Thus in a PAL receiver, the PAL switch which is in phase with the initial signal, may be found to be in antiphase with the faded in signal. In one arrangement to overcome this, Fig. 1, the two signals (FBAS) 1 and (FBAS) 2 , although line and frame synchronized are seen to have their alternations of the chrominance carrier modulation from Fa to Fb, out of synchronism by one line period, and signal (FBAS) 2 is accordingly delayed by one line period at 21 to produce a signal which, when chosen by switch 7, can be fed to fading arrangement 10, for fading on to the end of signal (FBAS) 1 . In the arrangement of Fig. 2, the signals are PAL type signals, containing the chrominance carrier F and its conjugated complex F* on alternate lines. Filters 11 and 13 separate the chrominance carriers F2, F 2 *, F 2 . . . from the signal (FBAS) 2 , to leave the components (BAS) 2 . The separated chrominance signals are fed directly to terminal 3 of switch 7 and also to modifier 15, which forms at its output the mirror image signal of its input signal about the (B-Y) modulation axis (see Fig. 3). Signal F 2 thus becomes F 2 * and F 2 * becomes F 2 . The thus modified chrominance signals are fed to the second terminal 5 of switch 7. Means, to be described, determines that the signals on terminal 3 are in phase with the chrominance carrier signals in signal (FBAS) 1 and switch 7 accordingly adds these signals to the (BAS) 2 components in adder 12, to produce the complete colour signal, which can be applied to fading arrangement 10. The PAL signals may comprise chrominance synchronization signals containing oscillations whose phase is switched over from line to line. In such a case, the connection of switch 7 to terminal 3 or 5 is controlled by a phase comparator 19, Fig. 4 (not shown) determining whether the oscillations in the two signals are in phase or in antiphase.

Patent ES-376456-A1 (ES)
Title: Electrostatic dust separator
IPC: B03C3/36
Filed: 1970-02-11
Abstract: In an electrostatic dust separator having a ionizing electrode axially disposed within a Venturi, an annular nozzle produces a spray of an auxiliary substance in the gas stream issuing from the Venturi, around a polarizing electrode. The coarse particles of the spray are electrified by influence and they attract and retain the finer ionized dust particles carried by the gas. The spraying nozzle may be disposed within an auxiliary Venturi to increase the velocity of the gas and to improve impact effects between the dust particles and the sprayed particles. The ionizing electrode is preferably formed with fins to enhance the ionizing corona discharge, while the polarizing electrode is on the contrary smooth to avoid any noticeable discharge effect. The gas to be treated may be fed into the inlet of the main Venturi by an injector nozzle to produce a negative pressure whereby a portion of the gas issuing from the main Venturi may be recycled into same through an annular passage provided around the said main Venturi.
