Title: Process for the manufacture of methyl mercaptan
IPC: B01J21/04
Filed: 1974-05-11
Abstract: Process for the synthesis of methyl mercaptan by the reaction of methanol with hydrogen sulfide wherein a high degree of conversion and enhanced selectivity for the product are obtained by dividing the quantity of catalyst utilized in the reaction into a minimum of three separate portions to form a plurality of reactive catalyst zones and introducing the total amount of hydrogen sulfide reagent into the first of such catalyst zones and thereafter introducing equivalent or alternatively different amounts of the methanol reagent into the consecutive interconnected catalytic zones to react with hydrogen sulfide flowing therethrough while maintaining a molar ratio of hydrogen sulfide to methanol between 1.1 and 2.5. By subdividing the catalyst into separate beds and introducing the reagents consecutively into the catalytic zones, it is possible to maintain the temperature of the reaction mixture within the optimum range and, therefore, to minimize deterioration of the catalyst due to excessive temperature and substantially eliminate the formation of undesired by-products.

Title: Fuel supply systems for heat generators
IPC: F02M69/20
Filed: 1976-03-18
Abstract: A fuel supply system for a heat generator comprises means for spraying fuel into an air inlet tube, which means are branched off a fuel supply line supplied by a pump having a fuel delivery greater than the fuel comsumption rate of the generator. The fuel line extends to a constant-level chamber by way of a variable-opening throttle element controlled in dependence upon the air flow through the inlet tube, the pump intake being connected to the constant-level chamber. A bypass circuit is adapted to connect the fuel pump output to a fuel reservoir and is closed by a calibrated valve which opens in response to a predetermined fuel pump delivery rate so that the fuel in the constant-level chamber is renewed when the rate of generator fuel comsumption is low.

Patent ES-8103521-A1 (ES)
Title: Gain controlled amplifier using a pin diode
IPC: H03G3/10
Filed: 1980-03-14
Abstract: A gain controlled amplifier is provided which is capable of handling a wide range of input signal levels without the need for input signal attenuation. A transistor is arranged in a common emitter amplifier configuration and includes a PIN diode as a controllable impedance in the emitter circuit. An input signal and a gain control voltage are applied at the base of the transistor. As the input signal level increases, the gain control voltage is decreased, causing an increase in the substantially resistive impedance of the PIN diode, which bears a constant relationship to the decreasing gain control voltage (i.e., a linear relationship on a semilog plot). The gain of the transistor amplifier is thereby reduced. At high input signal levels, the impedance of the PIN diode comprises a large resistive component in parallel with a large reactive (i.e., small capacitive) component at the emitter of the transistor, thereby affording substantial gain reduction. A novel PIN diode is provided for use in such a gain controlled amplifier, comprising a first localized region of high resistivity semiconductor material having a substantially planar surface. Second and third localized regions of one type conductivity are located in the high resistivity region adjacent to the surface. A fourth localized region of opposite type conductivity is located in the high resistivity region adjacent to the surface and intermediate the second and third localized regions, and is separated laterally from the first and second regions by zones of the high resistivity material.

Between the filter support and inlet is provided a distributing and air trapping chamber communicating with the individual blood-entering spaces and defining a space to receive blood from the inlet to trap air contained in the blood and present in the filter device to prevent the air from reaching the filter elements. A distributing piece, which serves to distribute blood introduced through the inlet into the distributing chamber to the individual filtering blood spaces, extends from the filter support into the distributing chamber.
Patent ES-8201769-A1 (ES)
Title: Photovoltaic cell suitable for manufacturing solar power units.
IPC: H01L31/07
Filed: 1981-01-30
Abstract: The invention relates to a low cost photovoltaic cell, using a minimum thickness layer of semiconductor compounds able to provide the photovoltaic effect and specifically in polycrystalline form. On a molybdenum sheet an auxiliary polycrystalline germanium layer is deposited in order to facilitate subsequent depositions. This is followed by an intermediate polycrystalline layer of gallium aluminum arsenide and an active layer of polycrystalline gallium arsenide. The presence of the intermediate layer with a wider forbidden band than that of the active layer compensates the effect on the efficiency of the limited thickness of the active layer.

Patent ES-8302786-A1 (ES)
Title: A process for the production of reduced iron and thermal cracking of heavy oils.
IPC: C21B13/00
Filed: 1981-12-21
Abstract: The invention provides a novel process for concurrently carrying out production of reduced iron and thermal cracking of heavy oils in which the reaction of thermal cracking is performed in a fluidized state with the fine iron ore as the fluidized medium and the particles of the iron ore become coated with deposits of the carbonaceous by-product material. The fine iron ore with the carbon deposited thereon is introduced in a fluidized-bed reducing furnace and there reduced into reduced iron by contacting with a reducing gas which is produced in a gas reformer from the cracked gas or the residual oil separated from the products of the thermal cracking. In an improvement of the above process, the gas reformer is operated as a fluidized-bed reactor with the reduced iron as the fluidized medium and acting as the reforming catalyst. The reduced iron partially re-oxidized in the reforming reaction is again reduced to completely reduced iron either by recycling into the fluidized-bed reducing furnace or by introducing into a second fluidized-bed reducing furnace.
Patent ES-8307146-A1 (ES)
Title: Metal pouring nozzle with gas inlet
IPC: B22D41/42
Filed: 1982-02-11
Abstract: A metal pouring ladle furnished with a sliding gate valve has a bottom pour opening fitted with a well block and a nozzle seated in the lower portion thereof, the well block and nozzle forming a flow passage leading to the valve. For introducing gas to the melt, a pipe is cast in the well block, the pipe opening to the bore of the well block above the nozzle or into an annular space encircling the top end of the nozzle component. This permits gassing before teeming commences without recourse to the flow passage through the nozzle, and so gassing is possible without disturbing any particulate silicious filler which may have been placed in the nozzle passage.
