Patent ES-362352-A1 (ES)
Title: Process and apparatus to control vi of solvent refined oil
IPC: G05D24/02
Filed: 1969-01-10
Abstract: Solvent refining of oil (in a vessel 13) is automatically controlled by a system in which the viscosity index of the refined oil (raffinate) is measured before the oil enters storage containers 37, 38 and the measured value, together with a target value, are used in a computation of an error signal which is then reduced by adjustment of a variable of the process affecting the viscosity index. The viscosity is determined at 41 by measurement of its refractive index in a side stream 35, 43 of the main flow to storage containers 37, 38 and the value fed to a computer 36. This includes an integrating stage and a desired value input to produce a signal which represents the viscosity error averaged over the contents of a storage container, and is used to control the proportionate flows of solvent S2 and charge S1 and the bottom temperature of the vessel 13 measured by resistance thermometer or thermocouple at 50. If there is a recirculating stage 60 its flow is also controlled by the computer. The computer may be of digital Fig. 2 (not shown) or analogue Fig. 3 (not shown) form. If digital, a number of alternative arrangements are described, some of which require a measurement of raffinate flow at 31 while others assume this to be constant the arrangements differ principally in whether it is the vicosity signal or the error signal which is integrated. In the analogue system it is the error which is integrated, and the flow is determined by the pressure difference across an orifice this yields the square of the flow so the square root is derived, which is then integrated to give the quantity of raffinate. The proportioning and the temperature controls may be used independently or jointly or successively, the temperature adjustment acting as a fine control when the proportioning is within a given range. The system may operate continuously or at prescribed intervals which are short compared with the time to fill a container. The temperature control loop comprises a side stream 26, 28 which circulates through a heat exchanger for heating or cooling, the flow of heat exchanger fluid being regulated by a valve 27 controlled by the computer, which effectively determines the reference value for this loop.

Patent ES-391032-A1 (ES)
Title: Astable multivibrator circuit with means for ensuring proper starting of oscillations
IPC: H03K4/64
Filed: 1971-05-11
Abstract: In an astable multivibrator circuit, a diode operates in conjunction with a voltage supply derived from the multivibrator output signal to insure the initiation of oscillations by limiting base drive current to the multivibrator transistors when power is first applied. This prevents saturation of both transistors and ensures sufficient loop gain to initiate oscillations in response to an unbalance in the system. As power is first applied, the diode is non-conductive and a relatively low voltage is applied to bias the multivibrator transistors. During normal operation, the voltage derived from the multivibrator output signal causes the diode to conduct, thereby coupling the base circuits to the operating potential supply. While conductive, the diode forward voltage drop compensates for changes in the Vbe of the transistors due to temperature variations and tends to maintain a constant charging current for the base circuits.

Patent ES-438130-A1 (ES)
Title: Coating composition and method of coating substrates therewith
IPC: C08G73/10
Filed: 1975-06-02
Abstract: A coating medium for application to a substrate to form a coating which is curable to a highly cross-linked polymeric state. A coating medium is prepared by reacting, in a suitable solvent for at least one reactant, an aromatic diamine and an aromatic dianhydride, with the reactants in the molar ratio of two-to-one respectively. The diamine is dissolved in a solvent, and the dianhydride is slowly added to the solution to form a diamide-diacid-diamine monomer. The reaction is carried out at a temperature below that at which imidization occurs. The reaction product may be made water soluble by the addition of a volatile base. A coating of the medium is applied to a substrate as a thin film and the film coating is cured at a temperature sufficient to form a highly cross-linked polymeric coating on the substrate. Suitable aromatic dianhydride reactants include 3,3',4,4'-benzophenonetetracarboxylic dianhydride and 4,4'-(2-acetoxy-1,3-glyceryl)bis-anhydro trimellitate, and suitable aromatic diamine reactants include 4,4'-diaminodiphenyl methane, 4,4'-diaminodiphenyl ether, and 1,3-diamino benzene. Upon application of a coating of the monomer solution to a substrate and upon cure of the coating to drive off the solvent and effect polymerization, intermolecular amidization and imidization reactions occur resulting in what are believed to be highly cross-linked ladder-type polymeric coatings.
