Title: Heat insulating fibrous mass
IPC: B29C57/00
Filed: 1968-05-10
Abstract: A mineral fibre mat is made by moving a stream of mineral, e.g. glass, fibres to a collecting means, causing a sheet of solid particles to flow homogeneously and at a constant rate (over surface 136), projecting the particles of the sheet into the stream of fibres by a gaseous current (issuing from slot 140) to homogeneously distribute the particles in the stream before it reaches the collecting means, spraying a thermosetting binding agent onto the fibres and/or particles before they reach the collecting means, and reducing the volume of the collected mass of fibres whereby the particles are homogeneously distributed therein on setting of the binder. The binder, e.g. phenol formaldehyde resin, can be sprayed onto the particles before they reach the fibre stream. The particles can be perlite, vermiculite, sand, ground glass, pulverised rock or pulverised slag. The particles can be passed along a rectilinear conveyordistributor and down chutes (as shown), or through an annular screw feed conveyordistributor (Figs. 14 and 15), before meeting an annular frusto-conical surface to form the sheet of flowing particles. The fibre-particle stream may pass through an oscillatable duct 144 and be collected on a conveyor subjected to suction.

Patent ES-373548-A1 (ES)
Title: Electronic converter
IPC: G01R19/00
Filed: 1969-11-14
Abstract: A circuit for producing a unidirectional output proportioned to the amplitude of an alternating voltage includes an operational amplifier 71 with a resistive feedback loop M1, a rectifying arrangement connected to the output of the amplifier and a second feedback loop M2. The rectifying arrangement incorporates the base collector diode of a transistor T2 and the second feedback loop is connected between the emitter of this transistor and the amplifier input. The second feedback loop allows the bias of the transistor T2 to vary such that the rectified voltage is proportional to the input voltage and steady. This circuit has a low threshold value and high stability. The negative feedback M1 stabilizes the D.C. operating point to such a level as to switch off the transistor T2. During positive half cycles of an input, transistor T1 bottoms and T2 is maintained cut off. During negative half cycles T2 conducts and the negative feedback circuit M2 functions to maintain the output voltage at T2 collector linear in relation to the input at I, the transistor current in T2 being essentially equal to the input current of T1. The rectified alternating voltage at the output may be filtered by a capacitor. If this is in parallel with the output load resistor RO, direct voltage proportional to the rectified mean value of the supplied voltage is obtained, while if connected between collector and emitter of T2, a direct voltage proportional to the peak voltage supplied is obtained.

Patent ES-390273-A1 (ES)
Title: Diaphragm for inverse osmosis and method of making same
IPC: B01D67/00
Filed: 1971-04-16
Abstract: The invention relates to a method of preparation of semi-permeable diaphragms, especially for use in inverse osmosis and enabling substantially pure water to be extracted from aqueous solutions of dissolved substances of low molecular weight, such as sodium chloride, saccharose, etc. The diaphragms for inverse osmosis essentially consist of a film-producing polymer having a sufficient number of mobile hydrogen groups to give, after reticulation, compounds which are insoluble in water. The method covers the preparation of ultra-thin layers which can be employed for hyper-filtration purposes, and also includes the superficial reticulation of a dry film of polymers which include, inter alia, the polyvinyl alcohols and polyvinyl pyrrolidone. The reticulation agent is preferably chosen from the di-isocyanates and may comprise a solvent for a swelling agent for the polymer and a catalyst for the reticulation reaction. An important feature of the invention is that the degree of reticulation of such diaphragms varies progressively throughout the thickness of the film, the most highly reticulated layer being a very thin superficial layer of the diaphragm.

Patent ES-407615-A1 (ES)
Title: Method for classifying particles
IPC: G01N15/12
Filed: 1972-10-13
Abstract: To enhance the selectivity of the electronic classification of particles which are to be sensed in an electronic field which includes a high frequency energization and which thereby employs the electronic opacity of the particles as a basis for their classification, the particles are treated, for example, by a lysing agent, which selectively causes the opacity of certain types of the particles to change whereby, each distinctive type of particle acquires a distinctive opacity range that is subject to electronic detection. Further selectivity can be obtained by electronically excluding after the treatment and before classification any undesired opacity range.

Title: Method for calibrating analytical moisture measuring equipment.
IPC: G01N5/02
Filed: 1979-12-14
Abstract: The water of crystallization of a ceramic material, kaolinite, is used as a standard for calibrating equipment used for measuring the amount of hydrogen in a nuclear fuel pellet. A kaolinite is heated to a temperature sufficient to drive out the water of crystallization in the kaolinite which is a precisely known amount and the amount is measured. Comparison of to the equipment readout with the known values determines the accuracy of equipment calibration. A nuclear fuel pellet is placed in the equipment and exposed to a temperature suffcent to drive off moisture therein after the equipment has been accurately calibrated. The hydrogen content is then measured to provide an accurate indication of total hydrogen content in the pellet.
