Patent ES-314092-A1 (ES)
Title: Improvements relating to microporous plastics sheet material
IPC: C08J9/26
Filed: 1965-06-11
Abstract: A microporous plastics sheet is made by mixing together a plastics material, a solvent therefore, and a particulate pore forming material to produce a dough, forming the dough into a strip, heating the strip to such a temperature (the "Thermal Shock Temperature") that the particles of pore forming material are exposed within the strip and substantially all the solvent is driven off, immersing the strip in an aqueous bath to leach out the exposed pore forming particles, and finally drying the porous strip thus formed. The plastics material may be plasticized or unplasticized PVC, low or high density polythene, polypropylene or polyurethane, the "Thermal shock temperature" being not less than 130 DEG C., 150 DEG C., 130 DEG C., 150 DEG C., 170 DEG C. and 185 DEG C. respectively. The pore forming particles may be salts of alkali or alkaline earth metals or ammonium salts, e.g. sulphates, chlorides and bicarbonates. In one embodiment (see all Figures, not shown) ground ammonium sulphate is mixed with powdered PVC at a station (30) and the mixture introduced into a twin screw mixer (60) during the passage through which a solvent and a minute proportion of a melting agent is added through a feed pipe (113), the dough thus formed being subsequently de-aereated. The de-aereated dough is then fed either directly to an extrusion die or, as in the example, via a granulator 17 and storage hopper, to an extrusion die, whence it is formed into a ribbed sheet. The sheet is then passed through successively hotter regions in a hot air oven (see Fig. 3) and heated to the required temperature, after which it passes through a series of water baths each successive one being higher than the next (see Figs. 4 and 5) so that a counter current of water is produced. The now porous sheet is finally passed to a drying oven (160) having successively cooled zones, to form the finished strip. Material suitable for clothing, battery separators or filters may be made.

Title: Control rod actuating mechanism
IPC: G21C7/12
Filed: 1966-09-28
Abstract: A control rod actuating mechanism for use with a liquid metal cooled fast reactor comprises elements 2 for gripping the top of the control rod 1, a rod 3 for actuating the gripping elements by displacement in a coaxial tube 4, means outside the reactor vessel for displacing the tube 4 through the reactor vessel wall, a metal bellows 10 as sealing means between the tube 4 and the actuating rod 3 and a gasket (not shown) as sealing means between the tube 4 and the reactor vessel wall, apertures 13 in the lower part 4a of the tube 4 which enable the liquid metal to flow freely through the tube 4, and guiding elements 14 rigidly connected to the tube 4 which make point contact with the actuating rod 3. The tube 4 is guided in its displacement by keys 15 which slide in longitudinal apertures 16 in a stationary outer guide tube. The liquid metal can enter the tube 17 freely through the apertures 16. The liquid metal provides continuous lubrication of the mechanism. The stationary outer guide tube is secured to a stationary tube which extends through the reactor vessel wall and supports a biological protection plug encircling the upper part 4b of the displaceable tube 4. The gasket which is located in the stationary tube cooperates with the displaceable tube 4 to bound a number of consecutive annular chambers and a sealing block. A small flow of gas derived continuously from a gas blanket above the liquid metal in the reactor vessel experiences a series of expansion steps in the annular chambers, the pressure differences being produced in a direction such that there is no leakage of active gas outside the reactor vessel. The gas circuit includes a reservoir, the dwell time of the gas in the reservoir being long enough for satisfactory deactivation. With such a gasket, high-speed rod movements of several metres become a possibility while on the other hand the movements of the bellows are short and slow with no maintenance problems arising.

Title: Aliphatic mercaptoanilides and their use as herbicides
IPC: A01N33/10
Filed: 1967-09-09
Abstract: The invention comprises aliphatic mercaptoanilides of the formula in which R 1 denotes an aliphatic hydrocarbon radical of 1-8 carbon atoms which may be substituted by halogen atoms and (or) hydroxy, alkoxy, carboxy, phenoxy or hydroxyphenoxy groups, R 2 denotes (a) an aliphatic hydrocarbon radical of 1-9 carbon atoms, which may be substituted by halogen atoms or hydroxy and (or) alkoxy groups or (b) a cyclopropyl, cyclobutyl or alkoxycyclopropyl group, R 3 denotes hydrogen or an alkyl group of 1-3 carbon atoms, X 1 denotes a hydrogen or halogen atom, an alkyl or alkoxy group of 1-4 carbon atoms or a haloalkyl group and X 2 denotes a hydrogen or halogen atom or a methyl or ethyl group. Many specific instances of the radicals R 1 and R 2 are given, including some alkyl, alkenyl or alkinyl groups which may carry substituents, as specified above. The compounds may be prepared (a) by reacting an arylamine of the formula with an appropriate carboxylic acid halide in the presence of a solvent and an acid-binding agent, or (b) by reacting an arylamine as defined above with an appropriate carboxylic anhydride, or (c) by reacting an arylamine as defined above with an ester of an appropriate carboxylic acid and an alcohol of 1-6 carbon atoms or phenol, or (d) by reacting an isocyanate of the formula with an appropriate carboxylic acid, carbon dioxide being split off, or (e) by reacting an arylalkyl ketone of the formula with hydroxylamine to yield the corresponding oxime, which is then subjected to the Beckmann re-arrangement. Method (d) is not applicable to the preparation of alkylmercaptoanilines which contain a carboxylic or hydroxy group in the side chain or which are alkylated on the nitrogen atom, and method (e) is applicable only when R 2 in the first formula above denotes an alkyl radical of 1-9 carbon atoms. Numerous examples are given. The products are useful as herbicides (see Division A5). 3 - Chloro - 4 - allylmercaptoaniline, an intermediate in the process, is prepared by treating 3,4 - dichloronitrobenzene with sodium sulphide to yield 2 - chloro - 4 - aminothiophenolate, which is then reacted with allyl chloride. A number of other intermediates obtained similarly from p-chloronitrobenzenes are listed.

Title: Silk screen printing machine for decorating conical articles
IPC: B41F17/28
Filed: 1967-11-18
Abstract: In a silk screen printing machine for multicolour decoration of frusto-conical articles A such as bottles, goblets and tumblers, each article is mounted in a rotatable work-holder 7 carried by an endless conveyer 6 below a series of stationary screens 8a, &c., with each of which the articles are brought into rolling contact, ink being pressed through the screens by squeegees 9a &c., which reciprocate at such a speed as to follow the line of contact between an article and a screen as it travels across the screen. Each article is held between a cap (30), Fig. 5 (not shown), which is pivotable between a loading and unloading position and an operative position, and a face plate (32) which is continually rotated by a pinion (38) fixed thereto and engaging a rack (39) extending the length of the chassis 3 on which the conveyer is mounted. The diameter of the pinion is made equal to the mean diameter of the article to be decorated, in order to register the impressions. The drive for the squeegees and for the conveyer is derived from a single motor (21), Fig. 1 (not shown), acting through a gear-box (24), the squeegee being reciprocated by a carriage (71), Figs. 5, 6 (not shown), having a cam follower (70) which engages a cam groove (67a) in a rotating drum (67), one revolution of the drum corresponding to one reciprocation of the squeegee. Different sizes and shapes of articles can be accommodated. The chassis 3 can be tilted about an axis 4 by screws 5 to angles dependent on the taper of the articles, the silk screens and squeegees can be raised and lowered, and the pinions exchanged to accommodate articles of different mean diameter, and the distance between the cap and face plate of each working head can be varied to fit articles of different lengths. The screens can also be moved longitudinally or transversely, with respect to the travel of the conveyer. Each screen may consist of a fine wire gauze whose meshes are blanked off except for a region corresponding to the design to be printed. In modifications, the squeegee may be temporarily fixed to the conveyer belt when the work head reaches the squeegee and each decoration section could include a plurality of squeegees.

Title: Machine with caterpillar mold for casting strips from nonferrous metals, especially aluminum and aluminum alloys
IPC: B22D11/06
Filed: 1968-09-05
Abstract: In a continuous casting machine of the type having a mould cavity defined by a co-operating pair of endless sets of mould blocks which are driven at the same speed so that over a portion of their run they engage with each other and define between them a moving mould cavity, the rear surfaces of the mould blocks 10 are connected to but spaced from a guide member 11 by supporting means constructed so that the blocks 10 are thermally insulated from the member 11 to the extent that the heat conductance from the casting wall to the rear surface of the blocks is at least 200 times the conductance of the path provided by the supporting means between the rear surface and the member 11. The mould blocks 10 are fastened to the guide member 11 by a steel bolt 15 which is pulled against the member 11 by means of a nut 16 with interposed cup springs 17, and are spaced from the member 11 by steel bolts 12 which have rounded ends and rest on hardened steel backings 13. Guide pieces 21, (22) and (23) fixed to the member 11 are slidably received in grooves 18, [19) and (20) in the block 10 and maintain a fixed point H of each block in a fixed position relative to the guide member 11 whilst allowing expansion and contraction of the block. The thickness of the mould blocks 10 is such that the rear portions of the blocks remain cool and thus restrain the casting wall from appreciable expansion or contraction. A reflective metal sheet 24 is arranged between each mould block and guide member. In another embodiment, Fig. 10 (not shown), the mould blocks are made from a number of plates (44) held together by tie rods (45). The plates may be made of different materials e.g. steel and copper, and may be spaced from each other by layers of heat-resistant material.

Patent ES-360606-A1 (ES)
Title: Method of manufacturing silicon carbide crystals
IPC: C01B31/36
Filed: 1968-11-23
Abstract: Silicon carbide crystals are prepared by heating granular silicon carbide, which may be formed in situ, provided with a core of silicon dioxide, either pure or in the form of sand or clay, at a temperature, e.g. 2000 to 2600 C., at which the core of silicon dioxide volatilizes, the silicon carbide coheres and crystals thereof form on the inner surfaces of the cavity so produced. In order to obtain the cavities of large dimensions which have to be formed in carrying out the crystallization in an Acheson furnace for example, cores may be formed locally by depositing sand 5 during the construction from a mixture 2 of sand with carbon or products supplying carbon upon heating. During the heating, e.g. by means of a carbonrod shaped electric heater element 3, the paper moulds 4 burn or char and the sand 5 of the cores volatilizes so that the surrounding silicon carbide coheres and caving in of the cavity, which is formed by complete volatilization of the sand core, is prevented. Generally, plateshaped silicon carbide crystals are formed, but if the crystallization is carried out in the presence of a Group IIIA element, particularly lanthanum, filamentary crystals or " whiskers " may be obtained.
