Title: Hydraulic system for feeding a plurality of independent hydraulic servo-operated devices
IPC: F15B11/20
Filed: 1977-07-19
Abstract: A hydraulic system for feeding a plurality of independent hydraulic servo-operated devices, such as servo-assisted brakes, clutch and/or servo-operated steering, in which a single pump draws fluid from a common reservoir and fluid pressure is automatically distributed by one or more modulating valves to the or each of the devices requiring power at any one time. The or each modulating valve comprises at least one piston in a cylinder, the piston being displaced by an increase in pressure due to displacement of one or more operating member such as brake or clutch pedal, or steering wheel, this controlling the flow of fluid through an axial passage in the piston by controlling its proximity to a valve shutter element and thereby controlling the fluid pressure in a chamber of the modulating valve, which pressure is fed to a control chamber of at least one distributor associated with a servo actuator of one of the servo operated devices of the system whereby to control the operating pressure applied to this.

Title: Public key cryptographic apparatus and method
IPC: G06F21/14
Filed: 1978-10-06
Abstract: A cryptographic system transmits a computationally secure cryptogram that is generated from a publicly known transformation of the message sent by the transmitter the cryptogram is again transformed by the authorized receiver using a secret reciprocal transformation to reproduce the message sent. The authorized receiver's transformation is known only by the authorized receiver and is used to generate the transmitter's transformation that is made publicly known. The publicly known transformation uses operations that are easily performed but extremely difficult to invert. It is infeasible for an unauthorized receiver to invert the publicly known transformation or duplicate the authorized receiver's secret transformation to obtain the message sent.

Patent ES-8502041-A1 (ES)
Title: Mouthpiece for divers and its use.
IPC: B63C11/26
Filed: 1984-03-30
Abstract: The mouthpiece (M) differs from hitherto known mouthpieces belonging to diving equipment by virtue of the fact that two diaphragms (4) are stretched between fork-shaped extensions (2) held between the teeth. When the mouthpiece is inserted into the mouth, these diaphragms (4) permit clear speaking. If an air-filled hose (7) is attached to the socket (3), the free end of which hose (7) is closed by a diaphragm (8), a diver can communicate under water with a second diver. To do so, the second diver only needs to hold the diaphragm to his ear. The mouthpiece thus permits both normal breathing and speaking. It can be used in both a demand regulator (6) and a snorkel.

Patent ES-8703380-A1 (ES)
Title: Waste disposal container closure mechanism
IPC: G21F5/00
Filed: 1984-08-23
Abstract: Closure mechanism for hermetically sealing a nuclear waste discharge container. The mechanism allows partial closure of the container after the internal apparatus has been inserted, leaving a smaller hole for introducing the waste material and processing it. Partial closure is effected by inserting, into the container, an inner ring which fits against the container and by tightening an outer ring-shaped cover over the inner ring, access to the container being permitted via the aligned holes. After loading the container with the waste material, a sealing disc joined axially to an internal obturator for allowing rotary but not linear movement is passed through the hole in the outer cover and it rests around the hole in the inner ring.

Patent ES-8606966-A1 (ES)
Title: Multiple rate baseband receiver
IPC: H04B3/14
Filed: 1985-02-21
Abstract: The present invention consists of a multirate data receiver which will recover data at any of N data rates with no predetermined restrictions on the value of N. The data rate at which the receiver operates is selected by a single 1-of-N switch selection. An equalizer section is constructed for each of the N data rates but are all controlled by the same (common) automatic adjustment circuitry, which controls gain and frequency compensation. The output from one of the equalizer sections is selected by an analog multiplexer constructed of field effect transistor (FET) switch circuits. The recovered waveforms from the equalizer sections are processed by common circuitry to recover the transmitted data. Clock recovery may be accomplished, for example, by a digital phase locked loop constructed such that the characteristics of the loop filters and divide-by-M feedback counters are easily modified by logical signals controlled by the 1-of-N switches.
Patent ES-8701433-A1 (ES)
Title: Monolithic integrated planar semi-semiconductor arrangement and process for its production.
IPC: H01L29/72
Filed: 1985-04-30
Abstract: A monolithic integrated semi-conductor arrangement in which the breakdown voltage is adjusted by a cover electrode (7) in the pn junction region. A suitable voltage is applied to this cover electrode (7) via a voltage divider (1) in order to adjust the breakdown voltage. To obtain a breakdown voltage which is essentially independent of temperature it is envisaged that the voltage divider(1) consists of diffused zones, which have differentiated dopings. The different temperature coefficients thus produced for the resistances (R1, R2) of the voltage divider (1) cause a temperature-dependent voltage change in the cover electrode , with the result that the breakdown voltage temperature is stabilized.
