Patent ES-8103718-A1 (ES)
Title: Gas-permeable refractory block and method of making this block.
IPC: C21C7/072
Filed: 1980-04-25
Abstract: The refractory piece permeable to gases according to the invention is designed to be incorporated in the inner refractory lining of a metallurgical container so that one of its surfaces will be in contact with the molten metal bath in said container, the opposite surface being equipped with means for introducing a gas under pressure. This piece, whose shape is generally hexahedral, consists essentially of a mass of nonporous refractory material that has a number of local discontinuities 8 extending throughout the piece along its height h between the surface in contact with the molten metal and the opposite surface. In an advantageous method of embodiment, the local discontinuities 8 are obtained by an assembly 1, in a metal casing, of nonporous refractory elements 2, in the form of plates and which are placed side by side along their large lateral surfaces, without any material gaskets or seals between them. The piece according to the invention is easy to make. In addition, it has all of the required qualities of selectivity or orientation so that its life will be about as long as the life of the surrounding refractory lining of the metallurgical container in which it is designed to go, while allowing the desired amounts of gas to be blown into the metal bath.

Patent ES-8306678-A1 (ES)
Title: Method and apparatus for producing high purity silicon from flames of alkalimetal and silicon halide.
IPC: C01B33/033
Filed: 1982-08-30
Abstract: Vaporized silicon tetrachloride is mixed with vaporized sodium in an exothermic reaction producing liquid silicon droplets and gaseous sodium chloride which are subsequently separated in an efficient manner. Separation of the silicon from the salt by-products is performed by a jet impaction separation technique wherein the products of the complete reaction between sodium and silicon tetrachloride are made to exit from a small hole (24) in the reactor (12) into a region held at a pressure less than half of the reactor pressure, A supersonic jet is thus formed which impinges upon a surface so that the direction of flow of the gas changes abruptly. The silicon droplets, however, are carried by their large forward momentum onto the surface where they are deposited. The salt vapor is then made to flow away from the depositing area and is passed over cooled surfaces where it is made to condense. Modifications of the basic technique allow the silicon to be collected in a variety of physical configurations including pellet form, crystal form, sheet form and ingot form.

Patent ES-8308079-A1 (ES)
Title: Operating, security and diagnostic device for the electrical system of a vehicle.
IPC: G01R31/00
Filed: 1982-11-23
Abstract: A circuit diagnosis and control device adapted to detect defects in a primary electrical circuit and temporarily discontinue power to the primary circuit in the event of a defect. A MOS transistor is connected in series with the power source and the primary circuit. A calculation device is connected with the MOS transistor and periodically tests a first voltage VGS, which may be different from zero, and a second voltage VDS, which must be higher than half of the voltage VBAT of the battery. In the event of a short circuit, the power is temporarily withheld from the primary circuit. An indication lamp may be controlled by the calculation device to inform the driver of the circuit condition. If VGS is not equal to zero and VDS is half of VBAT, a short circuit condition is indicated, for example, by a slow flashing of the indicator lamp. If VGS is equal to zero and VDS is less than half of VBAT, an open circuit condition is indicated, for example, by a rapid flashing of the indicator lamp. During normal operation, the indicator lamp remains continuously lit.
Patent ES-8401546-A1 (ES)
Title: Thread cutting device in lockstitch sewing machines
IPC: D05B65/00
Filed: 1983-02-11
Abstract: A thread cutting device for a lockstitch sewing machine having a rotary hook rotating in a horizontal plane, comprises a thread catcher which is pivotable in a horizontal plane and designed with a catch shoulder for needle and bobbin threads. The catcher cooperates with a stationary cutting tool as well as with a leaf spring which serves as a clamp for the end portion of the bobbin thread. The thread catcher is designed with a retaining shoulder by which the needle thread loop, upon being passed around the bobbin case, is caught and then released before being cut. The temporarily retained thread length substantially corresponds to the thread length which is pulled out sidewards while the thread catcher moves into its cutting position. Since no needle thread is thereby pulled off the thread supply by the thread catcher, only a minimum force is needed for moving the catcher.

Patent ES-8404084-A1 (ES)
Title: Electrothermal matrix addressable liquid crystal display.
IPC: G02F1/133
Filed: 1983-05-04
Abstract: A row (102-1) and column matrix (101-2) of strip electrodes is utilized for switching bistable liquid crystal display cells from the vertical state to the horizontal state via resistive heating by applying an electric current of sufficient magnitude and duration to selected electrodes (102-1, 102-2). Resistive heating causes the liquid crystal (130) to undergo a phase transition from the nematic mesophase to an isotropic phase. Extinction of the current permits the liquid crystal to cool preferentially into the horizontal state of the nematic mesophase. Horizontal-to-vertical state switching is performed by conventional electric field effect techniques. Faster operating devices are thus made possible.
