Patent ES-8102945-A1 (ES)
Title: Brake pressure control unit for vehicle brake systems
IPC: B60T8/26
Filed: 1980-06-27
Abstract: The control valve is disposed between the master cylinder and the wheel cylinder for controlling the brake pressure. The control valve comprises a differential piston which has a control force applied thereto and a valve which is controlled dependent on the movement of the differential piston. To achieve a very simple construction and a great variation of different control valve types employing largely identical elements, the control valve of the present invention includes a sleeve inserted into the housing bore and a screw-in cap to close the housing bore. Associated with the sleeve and the screw-in cap are spacer members to keep the sleeve in place. The differential piston is a stepped piston having an axial pressure medium channel with the end of this channel in the smaller diameter portion of the stepped piston cooperating with a valve closing member to provide the regulating valve. The smaller diameter portion of the stepped piston is guided in the sleeve and the larger diameter portion of the stepped piston is guided in a coaxial bore of the screw-in cap.
Patent ES-8206707-A1 (ES)
Title: Rotating sorter.
IPC: B07B1/20
Filed: 1981-02-20
Abstract: The disclosure concerns a rotary screening machine for moving pulp suspension through a screening slot and for separating impurities from the pulp suspension. An annular rotatable drum is surrounded by an annular porous screen basket that is spaced away to define a screening slot. Pulp suspension is delivered to one axial end of the slot and is discharged from the other axial end of the slot. Generally wedged shaped vanes, widening in the axial direction between the leading and trailing ends of the vane, are provided around the drum. The wedge defining surfaces may also be inclined with respect to a respective plane perpendicular to the axis. The space between the wedge surfaces is an open volume. A wall in that space is oriented to help create appropriate vacuum and eddy conditions behind the vane. The drum may have different zones, with the lower zone being provided with vanes and the upper zone being generally smooth. Other types of vanes or projections may be provided in the intermediate zone. Water sprayed into the slot dilutes the suspension. The configuration of the vane causes conveyance of the pulp suspension generally toward the impurities outlet and conveys the impurities to that outlet. The configuration of the vanes also causes the suspension to pulsate across the screen basket which dislodges pulp suspension fibers that otherwise might become matted on the screen.
Patent ES-8301152-A1 (ES)
Title: Method of controlling a power transmission device and control system for carrying out said method
IPC: F16H59/08
Filed: 1981-09-15
Abstract: A method of controlling a power transmission device between a driving engine and a drive axle comprising a torque converter and an automatic step gearbox, and a power transmission device for carrying out the method. In the gearbox, an electric control device with a microcomputer permits the operator to select, by means of a direction selector, the desired driving direction of the vehicle even when moving opposite to the desired direction. When such a directional command signal is sent to the control device, the reversing gear control reverses the working direction of the gearbox to make it work in the opposite direction to the driving direction. This signal is also sent to the drive gear control in the control device which during retardation maintains the engaged gear in engagement. If the highest gear is engaged when the command signal is changed, however, downshifting to the next higher gear immediately takes place which gear is then maintained during retardation. The reversing gear control is prevented from reversing the working direction of the gearbox if the vehicle speed exceeds a predetermined maximum value. The beginning of the retardation is then carried out with the working direction of the gearbox unchanged until the speed has dropped below that maximum, and then the working direction is reversed.

Patent ES-8303925-A1 (ES)
Title: Keyboard-controlled tissue stimulator based on a microprocessor
IPC: A61N1/08
Filed: 1982-04-29
Abstract: The keyboard-controlled tissue stimulator based on a microprocessor has pulse output circuits which emit output pulses at times and with amplitudes pre-determined by a microprocessor control arrangement. A microprocessor operates on the basis of user commands input via keys. The commands comprise a stop order which not only terminates the output pulses but also resets the amplitudes to a safe value, so that generation of unpleasantly high output signal levels is avoided on subsequent renewed starting. The OUT key producing the stop order is sited at a conspicuous point on the tissue stimulator housing, so that the user can stop operation very quickly in an emergency. Furthermore, keys for increasing and reducing the output amplitude are provided, and the microprocessor control arrangement responds to these commands in such a way that it changes the output amplitude continuously by pre-determined small increments for as long as the key is pressed. This permits the user to make gentle and accurate adjustments for optimum results. Another key orders the microprocessor control arrangement to switch over to another operation mode, for example pulse surge mode at a low rate.

Title: Method of generating halogen, an electrode-membrane assembly, an electrolytic cell and a semipermeable ion-exchange membrane for said method.
IPC: C25B9/23
Filed: 1982-07-30
Abstract: Aqueous alkali metal hydroxide is electrolyzed to generate elemental halogen in a cell having a sandblasted membrane (105) or other rough or abraded surfaced ion exchange membrane (105) with the rough surface exposed to electrolyte, While the surface may be on either the anodic or cathodic side lower voltage is attained when it is on the cathodic side, This is especially true when the cathode has an open structure and is in direct contact with the rough surface but unbonded thereto whereby liquid electrolyte is in ready contact both with the electrode and the membrane (105). The electrode is gas and electrolyte permeable and may be in the form of an electroconductive screen (108a, 114) or several electroconductive screens (108a, 114) in face to face contact. These screens (108a, 114) or opposed surtaces thereof may have different hydrogen or halogen overvoltages, Often in such a case the film or screen surface having the higher overvoltage is in contact with the rough membrane (105) surface and the surface or screen having the lower overvoltage is spaced from the membrane (105) with the higher overvoltage surface interposed between the membrane (105) and the lower overvoltage surface. The low overvoltage surface of course is in direct electrical contact with the higher overvoltage surface. Generally the surface having the low overvoltage is greater in area than the surface having the high overvoltage.

Patent ES-8505438-A1 (ES)
Title: Diatomite-modified pavement.
IPC: E01C19/10
Filed: 1984-01-13
Abstract: A method of making and the resulting diatomite-modified pavement. The addition of small amounts (0.5 to 2%) diatomite by weight to conventional pavement mixes, serves to increase density, viscosity, aggregate interlock and temporarily volumetrically extends the asphalt improving compactability resulting in an emplaced pavement that has lower air and water permeability without increased instability. The improved strength of the mixed and abrasion resistance of the mastic enable the thickness of wearing course overlays to be reduced without detrimental effects of wear life. The addition of diatomite makes the pavement mix more forgiving of errors in asphalt and aggregate amounts and can result in significant reduction of cost/sq. yard of pavement.
