Patent ES-2026624-T3 (ES)
IPC: G01D5/34
Filed: 1988-10-26
Granted: 1992-05-01
Abstract: In such a position measuring device for measuring the relative position of two objects (S1, B1), the division (T1) of a division carrier (TT1) is scanned by a scanning device (A1) which consists of a moving scanning unit (AE1a) and of a stationary scanning unit (AE1b). Whilst the moving scanning unit (AE1a) is connected to the moving object (S1), the stationary scanning unit (AE1b) and the division carrier (TT1) are mounted on the stationary object (B1). The stationary scanning unit (AE1b) contains an illuminating unit (BE) and two photo elements (P1a, P1b) and the moving scanning unit (AE1a) contains optical elements (KD, AP, US1, PF). Whilst only an optical effective connection exists between the moving scanning unit (AE1a) and the stationary scanning unit (AE1b), the stationary scanning unit (AE1b) is connected to the evaluating device (AW1) via an electrical cable (KB1) which transmits the two periodic scanning signals (S1a, S1b) of the two photo elements (P1a, P1b) to the evaluating device (AW1) for forming measurement values for the relative position of the two objects (S1, B1). <IMAGE>

IPC: C08G18/80

Abstract: The invention concerns a process for producing aqueous dispersions for subsequent processing to electro-dipcoat enamels with stoving temperatures less than 160 DEG C and stoving times less than or equal to 30 minutes. These dispersions contain binders in the form of modified epoxide and amine adducts and crosslinking agents in the form of polyisocyanates blocked with amino groups. In this process, polyepoxides and compounds containing one or more, preferably two, hydroxyl groups per molecule are converted at high temperatures by catalysis to epoxide-containing intermediate products. A solvent or solvent mixture is added under external cooling and a solution is boiled under reflux, if necessary under vacuum, until the temperature is reduced to between 95 DEG C and 20 DEG C. Amines are then added to the free epoxide groups still present in the epoxy resin and a dispersion is produced after addition of the crosslinking agent by addition of a water-acid mixture or a dispersion is first produced and a crosslinking agent then added.

Abstract: An active four-wheel steering system for motor vehicles, with steering arrangements for the front and rear wheels is described. These arrangements act as a function of driving-condition variables fed to an electronic control unit. A variable steering-lock angle ratio with respect to the front wheels is set, a first function converter of the control unit being supplied with the input signal relating to the steering-wheel angle by a steering-wheel angle sensor and with the further signal relating to the vehicle speed by a speed sensor. This function converter produces a first output signal for the lateral acceleration, which is fed as an input signal, together with the further input signal relating to the vehicle speed, to a second function converter. To allow for a change in the driving speed, the output signal relating to the lateral acceleration is fed, together with a signal derived from the change in the driving speed, to the third function converter. This input signal, calculated in the first function converter, and the input signals relating to the change in speed, calculated in the third function converter, are converted into an output signal for an additional rear-wheel steering angle, which is superposed on the output signal for the rear-wheel steering angle. The sum of these output signals is fed as steering-angle signal to the control unit for the purpose of controlling the hydraulic steering arrangement for the rear wheels. <IMAGE>

Abstract: 50 to 95 parts by weight starch and 5 to 50 parts by weight polyvinyl alcohol with a degree of saponification between 87 and 100% are thoroughly mixed and furthermore the moisture content of the mixture is regulated between 10 and 25 weight %. Subsequently the mixture obtained is subjected to a thermo-mechanical treatment at a temperature situated between 110 and 180 DEG C. During the extrusion the mixture is subjected to shearing forces so that the product obtained when it is dispersed in cold water and subsequently is centrifuged, divides into a watery phase and a coacervate phase without a sediment of undissolved polyvinyl alcohol being formed.

Abstract: A device consisting of a deformable support equipped with at least four independent wheels (5, 55 and 45, 65) and comprising a horizontal transom (3) and two sole bars (4, 44) which pivot and can be inclined relative to the transom (3). 
<??>The two sole bars (4, 44), each provided with at least two wheels (5, 55 and 45, 65), are mounted on articulated elements (7, 47) fixed to the transom (3) on either side of the longitudinal axial vertical plane of the vehicle, such that the articulation pivots (for example 18, 38, 52, 91) of the sole bars (4, 44) have variable relative positions. This results in a compensation of the reduction in distance between sole bars (4, 44) which occurs when they pivot, and hence a constant good match between the spacing of the wheels (5, 45, 55, 65) and the width of the track.

Abstract: After reaching a temperature of about 450 DEG C, the flue gases formed in the fire space (1) of the furnace are brought to a temperature of 200 - 250 DEG C by abrupt cooling (4). This abrupt cooling (quenching) is preceded by utilisation of the heat of the flue gases in a high temperature stage (2) from 1000 - 1200 DEG C to about 450 DEG C and the abrupt cooling is followed by a low temperature stage (6) from 200 - 250 DEG C to about 150 DEG C. This avoids a new synthesis in which dioxins and furans are formed from the components of the flue gases and the fly ash.

Abstract: A device for attaching an accessory (10) to first and second spaced-apart elements (16) affixed to a bicycle and defining an opening between them, which opening has a minor dimension and a major dimension, comprises a support member (20) and a cleat member (18), each of which has a medial portion (20a, 18a) adapted to span the minor dimension of the opening and a leg portion (20b, 18b) extending out from each of the opposite ends of the medial portion (20a, 18a) for engagement with opposite sides of a respective one of said elements (16). The overall dimension between the outer ends of the leg portions (18b) of the cleat member (18) is less than the major dimension of the opening so that the cleat member (18) can be inserted in the opening by aligning it with the major dimension of the opening and then repositioned to align it with the minor dimension and engage the leg portions (18b) with the bicycle elements (16). Components (18b, 22, 24, 26) are included for fastening the cleat member (18) to the support member (20), fastening the accessory (10) to the support member (20), and releasably connecting the support member (20) to a third element affixed to the bicycle to prevent the cleat member (18) and support member (20) from rotating or translating relative to the first and second elements (16).
