Patent ES-456897-A1 (ES)
Title: Tandem brake master cylinder
IPC: B60T11/20
Filed: 1977-03-16
Abstract: A brake master cylinder contains a primary and a secondary piston each having an associated brake fluid reservoir and compensator valve. Normally, the primary piston is actuated directly by mechanical force and the secondary piston is actuated by fluid pressure acting on it from the primary cylinder. If brake fluid pressure fails in either primary or secondary piston regions, the unfailed piston thereupon responds directly to mechanical actuating forces to produce normal brake fluid pressure in its associated wheel cylinders without interference from the failed piston.

Title: Motor vehicle battery charging installation
IPC: H02J7/14
Filed: 1979-01-31
Abstract: A motor vehicle battery charging installation includes an alternator/rectifier combination which is controlled by a voltage regulator and is connected to the battery. A warning lamp is connected in series with the collector-emitter of a control transistor across the battery. The voltage at the base of the control transistor is determined by a resistor/capacitor/diode network connected to the rectifier output and to a phase point of the alternator to turn the lamp on whereas the alternator is producing no output. A zener diode is connected to the rectifier output and to an auxiliary input of the regulator to take control should the connection between the alternator and the battery become interrupted. Current flow through this zener diode is detected by a second transistor with its collector-emitter parallel with the first-mentioned transistor so as overridingly to illuminate the lamp in the event of the zener diode becoming conductive.

Title: Method of controlling pumping water-wheel
IPC: F03B15/06
Filed: 1979-04-11
Abstract: A method of controlling a pumping water-wheel having S-shaped characteristic curve in its operating region. This invention intends to detect the behaviours of the operating point of the water-wheel in the S-shaped characteristic portion by the use of the number (N) of revolutions per unit time or acceleration (dN/dt) of the water-wheel.

Patent ES-8203063-A1 (ES)
Title: Process for producing hydrogen fluoride and phosphoric acid
IPC: C01B25/18
Filed: 1981-05-07
Abstract: An improved method for producing hydrogen fluoride from fluoride bearing ores, such as fluorospar and fluorapatite, by reaction of the ore as a slurry in fluorosulfonic acid. The slurry is heated by the exothermic heat of the reaction to vaporize volatile phosphorous compounds and substantial quantities of hydrogen fluoride. The calcium fluoride is substantially reacted to form hydrogen fluoride. High silica fluorospar ores can be used since silicon tetrafluoride is not formed with fluorosulfonic acid. Another feature provides for addition of calcium fluoride to the slurry to react with the by-product sulfuric acid in the residual solids to eliminate the sulfuric acid recovery step in the process. Hydrogen fluoride produced is recovered, together with the hydrogen fluoride produced from the hydrolysis or pyrolysis of the intermediate fluorophosphorous compounds. Additionally, at least a portion of the hydrogen fluoride can be reacted with sulfur trioxide to form fluorosulfonic acid for makeup in the process.

Patent ES-8309045-A1 (ES)
Title: Bus contention resolution in data processing apparatus having multiple independant users.
IPC: G06F13/374
Filed: 1982-11-02
Abstract: A multiple user shared bus contention resolution facility permits processing elements (PE's) to communicate with other PE's entirely under the control of each PE without a separate bus controller. Each PE has means for broadcasting its priority code on a contention portion of the bus and for sampling the bus after a delay in which it has received the codes from other PE's. Each PE holds its priority code on the bus for a further delay during which other PE's can sample the priority code. The PE's resolve contention for access to the information portion of the bus in a multi stage contention sequence. System usage, made possible by peer-to-peer distribution of bus access control, includes dynamic driven priority schemes, a variety of operating modes and hence flexible multiplexing of message traffic.

Title: Circuit arrangement for reversing and adjusting variable linear voltages
IPC: G01B15/02
Filed: 1983-07-27
Abstract: The invention relates to a circuit arrangement for reversing and adjusting variable voltages, such as can be tapped as a measure of the material thickness or density in measuring instruments which operate with radioactive radiation and scintillation measuring probes in order to determine the thickness or density of materials at a logarithmic amplifier which is followed by a pulse density meter, and serves the purpose of simple representation of the exponential relationship between the material thickness or density and the number of output pulses. The conversion and adjustment of the voltages is performed by feeding these voltages to a non-inverting operational amplifier, whose gain can be continuously controlled, in the circuit arrangement via an input voltage divider and, furthermore, by counterconnecting the output voltage of the operational amplifier to a compensation voltage, the stable countervoltage required for the compensation being obtained by dividing the operating voltage. The difference voltage obtained is present at the input of an AD converter with a digital decimal display. Control is such that the difference voltage is "zero" given a maximum input voltage.
