Patent ES-469173-A1 (ES)
Title: Method of bonding a bioglass to metal
IPC: A61L27/30
Filed: 1978-04-26
Abstract: A method of bonding a bioglass layer to a metal substrate comprising heating the metal substrate having a roughened, oxidized surface to about a temperature at which the expansion of the metal is substantially equal to that of the bioglass at the temperature above which the thermal expansion of the bioglass is non-linear, immersing the heated metal surface in molten bioglass, the time of immersion being of such duration that the temperature of the metal does not rise substantially above the temperature to which it is heated, allowing the coated substrate to cool whereby the bioglass layer is bonded to the metal substrate by ion diffusion and thermo-mechanical stresses in the bioglass and metal layer are relieved at a substantially equal rate and the product produced by said process.

Title: Raw mineral material consisting of triple mineral layers having reversiblly expansible crystal state on large area* and having mutually separated crystal layers
IPC: C23C26/00
Filed: 1978-07-11
Abstract: Mineral is based on a reversibly swellable 3-layer mineral of large-faced crystalline type, with disconnected crystal layer. This is produced from fine-grained vermiculite, hydro-mica or even nonswellable mineral with these minerals deposited within the crystals with >50 (>75)wt. % tabular crystals with extremely thin, uniformly planae tubular crystals with a thickness of 0.5-10(0.5-5) mu m and face dimensions corresponding to an equiv. dia. of 10-200 mu m and a ratio of thickness/equiv. dia. =1.10, (=1.20). The particles have hydrophilic properties at the planar faces, which rapidly take up or yield polar liquids, such as water, and strong adhesion or cohesion, which leads to shrinkage only in one direction, i.e. perpendicular to the tabular plane, on drying the particles from a dispersion in a polar liquid (water) or moistening the dray material. The particles lie over one another in layers and gave a plasticity of 35-65 wt. % dry material w.r.t. the moist material. Mineral is used partic. as refractory binder for the prodn. of mouldings and films and as release agent. It is also useful as carrier for various materials, e.g. plant protection agents.

Title: Apparatus for watering and draining soil
IPC: A01G25/06
Filed: 1978-08-22
Abstract: A double-duct conduit for irrigation and drainage comprises an inner small-diameter duct secured eccentrically inside an outer large-diameter duct with the walls of the ducts closely adjacent to one another along their tops. Ports through the wall of the inner duct are spaced above the bottom thereof, to provide a sump in its bottom and are spaced below its top to provide an air chamber above the sump. The outer duct also has ports through its wall, at its opposite sides, spaced below the level of the bottom of the inner duct but a little above the bottom of the outer duct, providing a shallow sump in the bottom of the outer duct and an air chamber thereabove. During irrigation, water falls from the inner duct to the sump in the outer duct, then flows out through the outer duct ports. For drainage, water rises in the outer duct to the level of the ports in the inner duct, while slime and sediment remain in the sump in the outer duct.

Title: Retrace blanking pulse generator with delayed transition
IPC: H03K4/62
Filed: 1978-08-31
Abstract: A delayed transition kinescope blanking pulse generator has a switch controlled by the deflection synchronizing pulses.

The interval between the intants of closure of the two switches represents the amplitude and rapidity of movement of the object. Slight displacements or vibrations will not cause both switches to close due to the distance separating them but sudden violent displacements caused by a bag being snatched will cause an alarm. - The switches may be constituted by interdigitated printed conductors on a circuit board, the spacing between the conductors being such as to allow them to be bridged by the conductive sphere. Various forms of electronic monitoring circuit are described to trigger an alarm device in response to the two switches being closed in response to violent movement of the conductive sphere, using bistable circuits. The path has zones of differing curvature to provide a variation of the movement sensitivity.  (4/55)

Title: Polyamide membrane with controlled surface properties and process for its production.
IPC: C12N11/08
Filed: 1983-02-04
Abstract: Surface modified, skinless, hydrophilic, microporous, polyamide membranes with controlled surface properties are prepared by the steps of preparing a casting solution comprised of (A) a casting resin system comprised of (a) an alcohol-insoluble polyamide resin, and (b) a water-soluble membrane surface modifying polymer having functional polar groups and a molecular weight of 10,000 or greater, and (B) a solvent system in which the casting resin system is soluble inducing nucleation of the casting solution by controlled addition of a non-solvent for the casting resin system under controlled conditions to obtain a visible precipitate of casting resin system particles, thereby forming a casting composition spreading the casting composition on a substrate to form a thin film contacting and diluting the film of the casting composition with a liquid non-solvent system for the casting resin system, thereby precipitating the casting resin system from the casting composition in the form of a thin, skinless, hydrophilic, surface modified, microporous, polyamide membrane and washing and drying the membrane. The membranes of this invention are characterized by having fine pore ratings, the surfaces properties thereof being substantially controlled by functional polar groups of a membrane surface modifying polymer and having the capability, through the functional polar groups of the modifying polymer, of reacting or interacting with particulates and/or nonparticulates in a fluid. Membranes of this invention are useful in removing metal species from aqueous streams and in immobilizing enzymes. Membranes of this invention also have enhanced filtration efficiency over a broad pH range with very fine contaminants, particularly very fine positively charged particles, such as asbestos.

Title: Proximity switch circuit.
IPC: H03K17/95
Filed: 1983-06-10
Abstract: The circuit operates a main switch SCR to pass an a.c. supply V through a load L when a metallic object is in proximity to coil L1. Coil L1 is driven by an oscillator comprising transistor T2 and associated components. SCR is gated on simultaneous occurrence of an output from level detector T3 and a signal from T5, these being ANDed by T4. The timing of the signal from T5 in the supply cycle is governed by the RC time constant of C4,Z1,R14 and is such that the power supplied to the oscillator and level detector is the minimum necessary, for a wide range of supply voltage and load current.

Title: Time sharing conference circuit for digital system
IPC: H04J3/00
Filed: 1983-09-27
Abstract: Address information detailing which receiving and transmitting channels are being used for a conference is stored in RAM's. The speech is sampled in PCM format from each subscriber and is passed via a channel counter and multiplexed to a reception memory. This data is then transmitted from the memory to a comparator which selects the subscriber having the loudest signal. A latch circuit retains the current loudest signal and a timing circuit allows it to be retained for a given time period. A logic control circuit provides control signals when another subcrriber comparator circuit produces an output signalling the channel having the loudest signal. This process is repeated for each frame of information.
