Patent ES-344568-A1 (ES)
Title: Improvements in or relating to Microporous Plastics Members and Process for Making Same
IPC: H01M50/417
Filed: 1967-08-29
Abstract: A microporous plastics member, e.g. battery separator sheet, is made by forming a coherent dough by mixing a thermoplastic resin with a plasticizing amount of a first solvent and with finely divided particles of a filler which contains a volatilizable constituent releasable therefrom by heating and which shrinks irreversibly on release of this constituent, forming the dough into a shaped member, extracting the first solvent from the member by contacting it with a second solvent at a temperature below the b.p. of any liquid present, the second solvent being one which can dissolve the first solvent without dissolving the resin and filler, thereby deplasticizing the member, and then heating the member without softening the resin contained therein until the filler is shrunk within the member by release of its volatilizable content. The resin may be polyethylene, polypropylene, polystyrene or polyvinyl chloride. The filler may be powdered hydrated silica, silica hydrogel or diatomite with absorbed water. The first solvent may be a ketone, e.g. cyclohexanone and the second solvent may be water. In the examples, the dough was shaped by extrusion into a sheet.
Patent ES-344739-A1 (ES)
Title: Composite sheet adhesives
IPC: C09J7/30
Filed: 1967-08-26
Abstract: A laminate comprises a protective carrier sheet having a release surface and an adhesive sheet material comprising (a) a first layer comprising an activatable adhesive composition and (b) a second layer comprising an anti-blocking composition which second layer is adhered to the first layer and is lightly adhered to the rear surface of the carrier sheet so that the carrier sheet can be stripped from the second layer of adhesive sheet material, the anti-blocking composition being such that when the carrier sheet is stripped from the second layer of adhesive sheet material the adhesive composition is activated and the adhesive sheet material pressed against a surface to bond it thereto the antiblocking compositions is at least partially displaced to permit the adhesive composition to adhesively engage the surface and bond thereto. The adhesive composition may be heat-activatable and anti-blocking composition may be a thermoplastic material having a melting point not less than 20 F. lower than the activation temperature composition. In such cases the antibonding composition may be soluble in the molten adhesive composition. The second layer may have a thickness of 0.0001 inches or less. The adhesive composition may be formed of a thermoplastic polyester formed from glycol and an aromatic or saturated aliphatic dicarboxylic acid, such as polyesters formed from butylene glycol, ethylene glycol and polypropylene ether glycol and terephthalic or isophthalic acids or such aliphatic acids such as sebacic, azelaic and dimerised linoleic acid. A preferred polyester is a condensation product of terephthalic acid, isophthalic acid and sebacic acid with 1,4-butanediol. Other adhesives specified are polyamides, polyester amides, or acrylic and methacrylic resins and mixtures of polyethylene and other resins as well as those comprising natural rubber or butadiene-styrene copolymeric rubber which are particularly suitable when the antiblocking material comprises polyethylene. Suitable anti-blocking compositions include homopolymers of ethylene, copolymers of ethylene with vinyl acetate or alkyl acrylates such as ethyl acrylate, natural waxes, high molecular weight wax-like polyethylene glycols, paraffin wax and polyisopropylene or mixtures thereof. The laminate may be made by depositing the layer of anti-blocking composition onto the protective carrier sheet and subsequently depositing the layer of adhesive composition onto the layer of anti-blocking composition. The deposition may be effected by spraying, brushing or dipping using solutions in volatile organic solventsemulsions or as hot melts. The protective carrier sheet may be paper and may be coated with or impregnated with a silicone composition or with polytetrafluoroethylene.

Patent ES-348718-A1 (ES)
Title: Circuit Arrangements for Current Consuming Apparratus
IPC: H05B39/08
Filed: 1967-12-28
Abstract: A system for supplying from an A.C. source a load having a positive temperature coefficient of resistance is so arranged that the current flow in the load at starting is reduced. A load 3 such as an incandescent lamp is supplied from an A.C. source 1, 2 by way of a pair of reverse parallel connected thyristors 6, 11, the control signals for which are derived from a circuit comprising capacitors 7, 10 and resistors 8, 9, the resistor 8 having a negative temperature coefficient of resistance. When switching on the resistor 8 is cold and has a high resistance. The capacitors 7, 10 will-in consequencetake a relatively long time to charge to a value sufficient to break down the DIACS 14, 17 and supply the thyristors 6, 11 with trigger signals. The current flow in the lamp 3 will therefore be small. As the resistor 8 warms up and its resistance falls, the capacitors 7, 10 will charge more quickly. Thus the thyristors 6, 11 will fire earlier in the respective half cycles of the A.C. supply and the current flow in the lamp 3 will increase until the normal current flow is reached. If desired the resistor 9 may be a variable resistor by means of which the current flow through the lamp 3-and hence its brilliancy-may be controlled. In another embodiment the thyristors 6, 11 may be replaced by a TRIAC in which case the control circuit will comprise only one of the capacitors 7, 10.

The warning device has a pin 11 which can be operated by a sleeve member 4 axially displaceable in the master cylinder in dependence upon the hydraulic pressure in the working chambers 9, 10 of the dual-master cylinder illustrated and the pin extends radially out of the master cylinder casing 7 such that an electrical contact 16 may be operated by the pin 11 and also by a float member 13 to switch on the warning device in the event of a pressure failure in one of the brake circuits or should the level of the liquid in the fluid reservoir 12 fall. The pin 11 is spring urged into engagement with a recessed portion 17 on the sleeve 4 and is adapted to move upwardly when the sleeve member is moved to the left or right depending on failure of one or other of the brake circuits to actuate the electrical contact 16. As shown in the functional Fig. 2, the electrical contact 16 is disposed in the cover 18 of the supply reservoir 12.

Title: Method and apparatus for making hollow bodies of concrete or the like
IPC: B28B21/28
Filed: 1969-07-28
Abstract: Pipes having dense, watertight concrete walls are produced by vibrating a rotating mould suspended on a roller shaft as the mold is being filled, and continuing its rotation without vibration for a short time after the mold is filled. Vibration is attained by ridges or fingers which can be made effective, or not, to vibrate the mold as it is rotating. In one form, fingers on a roller shaft are slidable between ineffective positions and positions where they serially engage a smooth running surface on the mold. In other forms, a mold is movable from a position where it is supported by engagement of a ridged running surface on either the roller shaft or the mold with a cylindrical surface on the other to a position where the cylindrical surface on the mold runs on the roller shaft or on an auxiliary sleeve without vibration.
